Cape Neddick through Wells – Snowy Owl!

Jeannette and I birded from Cape Neddick through Wells on Tuesday, seeing a really pleasant variety of birds in the process in the calm before the storm. Delayed by a snowy start and somewhat slick roads (OK, not slick if didn’t drive like it was a dry race car track – 7 cars were off the road between Freeport and York, however) that backed up traffic (“Hey, there’s a car in the ditch, let me look!”), we didn’t reach the Nubble neighborhood until almost 9:00, but by then the snow had ended, the ceiling lifted a bit, and a very light wind made for decent  – albeit a bit raw – birding conditions.  Although we didn’t have anything earth-shattering, we did have a fair number of “good birds.”

Without a day off together in December (the store is open seven days a week from Thanksgiving to Christmas), our annual late November run through our usual route is the last time we focus on thickets and migrant traps in the hopes for lingering migrants and rare passerines.  Next time, waterbirds will be more of a focus.  And the limited number of non-resident passerines that we detected today (other than Dark-eyed Junco, White-throated Sparrows, American Tree Sparrows, and a scattered few Yellow-rumped Warblers) confirms that – as did the impressive, and growing, quantity of waterbirds.

Three Carolina Wrens was the highlight of a thorough check of the Nubble neighborhood thickets, although we did have a group of about 40 Snow Buntings fly over.  45 Black Scoters, 13 Purple Sandpipers, 8 Great Cormorants, 6 Harlequin Ducks, etc at The Nubble were a sign of things to come along the shoreline.

Passerines were few and far between along Marginal Way and the adjacent neighborhood, but great numbers of waterfowl along the shoreline more than made up for it.  As with everywhere we looked at the ocean today, all three scoters were present in numbers, including a close and talkative group of about 100 Black Scoters.  Lots of Long-tailed Ducks, Common Eiders, and a total of 20 or 21 Harlequin Ducks were also present, along with a half-dozen Purple Sandpipers.

OgunquitBeach was a hotspot today, with a flock of 75-100 Sanderlings being joined by 32 Dunlin.  200+ Mallards and a handful of American Black Ducks were in the river, and a Belted Kingfisher hunted from its shore.  One of the surprises of the day was two Ruby-crowned Kinglets actively foraging in four Dwarf Alberta Spruces in planters in front of the motel.  A Winter Wren at Beach Plum Farm was a very good bird for this late in the season (they’re the “All but in winter wren” in Maine), and we had two Peregrine Falcons and an immature Northern Harrier in and around Harbor Road and Community Park in Wells.

We checked WellsHarbor and the jetties from a couple of vantage points (wouldn’t this be a perfect place to find a Ross’s Gull!?) and then scanned the offshore rock ledges still above water on the incoming tide from the parking lot at the end of Mile Road.   Six more Dunlin were within the scattered flock of 75+ Purple Sandpipers, and there were a lot of the expected waterbirds, including 6+ Red-throated Loons and at least four Red-necked Grebes.

All day long we were scanning the marshes and shoreline rocks in the hopes of seeing a Snowy Owl.  There have been a rash of reports in the past 7-10 days, as it looks like an irruption is underway.  I have not heard any reports of lemming and vole populations on the tundra, but a southward push of Snowies means there are either too few rodents (a natural cyclical crash, especially in lemmings) or too many owls (good breeding productivity thanks to a boom year in lemmings).  Either way, there are a lot of hungry owls around Maine right now.  It was surprising that based on the recent uptick in reports, we did not see one all day…until our very last stop with the light rapidly fading.  One immature female-type (extremely heavily barred throughout the body, other than the face) was standing guard on the last of the rocking ledges that I scanned.  Any day with a Snowy Owl is a good day in my book!

Please remember that these birds are not down this far south by choice!  The birds are here because they are hungry, or even starving (one emaciated bird was found dead at Prout’s Neck the other day, for example).  While this charismatic and captivating species is sought by birders, photographers, and almost everyone else, we must be mindful of the dire straights that many of these birds are in.  Too often we have heard stories of birds harassed, flushed repeatedly, or otherwise bothered by supposed fans.  In the case of a Snowy Owl perched on a rock 100 yards or more offshore, there is little harm that can come from gawking at them from land.  But when they are in the marsh, in the dunes, out in a field, on a building, etc, how about we remain just as respectful to these magnificent creatures and admire them from a safe distance.  Besides, the birds’ natural behaviors will be more fascinating than watching it fly away from you.  No, you really don’t need to see the bird a little better, or get a photo a little closer . . . admire them from a distance and let’s not make life any more difficult for these birds – or ruin it for other birders!

Rarity Season-to-date in Review

I hope you didn’t think that my lack of blogging of late equated to a lack of birding!  Quite the contrary, actually – it is Rarity Season afterall!  I’ve just been posting more frequent, shorter updates on our store’s Facebook page (you can scroll through the timeline here to see recent posts), especially since I have found myself a bit over-extended with a variety of other projects at the moment – I’ve been working late most nights recently to make up for my morning birding gallivanting.

In fact, I have been birding even harder than usual – if you can believe that!  Spurred on by extraordinary late October finds of an “Audubon’s” Yellow-rumped Warbler at Fort Foster and a Bell’s Vireo (a state bird for me!) on Bailey Island, I found myself somehow even more motivated to beat the bush through the first half of November.  In addition to the 10th Annual South Coastal Maine Rarity Roundup that I organize every year, I worked hard at various traditional hotspots, favorite late fall patches, and various attempts to think “outside the box,” such as walking the 4.5 miles into work today to check a handful of swales and thickets en route (not very productive, except for the exercise, for the record)

While Audubon’s Warbler and Bell’s Vireo are going to be tough to beat – the early-rarity-season bar was set awfully high! – I have had some outstanding birding in November, even if there has yet to be another “Mega.”  Personal highlights in the first half of November include a very nice variety of lingering (pioneering?) warblers, a Yellow-breasted Chat, multiple Orange-crowned Warblers (I’ve had four this season to date), huge numbers of Ruddy Ducks on Sabattus Pond, and overall just really good birding with good diversity.

Elsewhere around the state, current highlights include a Northern Hawk-Owl in Lincoln – not a vagrant in the “Rarity Season” sort of way, but exciting nonetheless!  And perhaps that, along with an early Snowy Owl report from Biddeford Pool, portends a decent owl irruption this winter?  There certainly won’t be any winter finches around this year.).  Other birders have detected a variety of late warblers around the state (wow, November Chestnut-sided in Falmouth!), and lots of lingering shorebirds – especially in Scarborough Marsh.  But as far as the first half of November usually goes, there have been no truly exceptional birds.  Looking around the region, we see goodies such as a Calliope Hummingbird in New Hampshire, A Black-chinned Hummingbird in Connecticut, and the usual fun array of rarities in Massachusetts (Scissor-tailed Flycatcher, Yellow-headed Blackbirds, Western Tanager, American Avocet, etc).  However, it is an ultra-spiffy adult Ross’s Gull near Montreal that is the real headliner of the fall in the Northeast so far (and yes, I am being tempted to chase this, I have to admit).

So there are some good birds around the region, and no doubt there are some good birds still to find in Maine.  Other than a couple of days, it has been fairly temperate to mild all fall, and I can’t help but wonder if birds that arrived in the state through various vagrancy mechanisms (see Chapter 7 of my book, How to Be a Better Birder) have yet to concentrate along the coast as they seek out more favorable microclimates or seasonal food sources.  Also, as the season progresses, more rarities turn up at feeding stations as natural food supplies diminish.  December rarities, for example, are often discovered at feeders.  Two tardy Chipping Sparrows are at our store’s feeders as I type this, by the way; I’m hoping they pick up a clay-colored cousin.  A lot of folks are reporting very busy feeders right now, which is a good sign, especially considering the lack of irruptive finches.

The last few days have seen a nice southwesterly flow aloft.  Look at Friday’s wind map, for example:
wind map,11-15-13

That extensive southwesterly flow early in the month would have surely deposited stuff like Cave Swallows in New England, but I wonder if that window has already closed.  A couple of Caves in Connecticut as recently as the 9th gives me some hope, however.  Contrast that map with the more zonal flow that we have seen for much of the month, such as on 11/10:
wind map,11-10-13

Although few birds are “blown” out of range, certain winds facilitate the arrival of more vagrants in certain areas than others.  And southwesterly winds in late fall are definitely the desired winds here in Maine.  With a fairly complex weather system on its way – including some really severe storms in the Midwest – I remain hopeful for some more out-of-range treats.  Interesting weather does have the tendency to produce some interesting birding, even without facilitating the arrival of rarities.
surface map, 11-17-13

At the very least, behind this system, we should see a return to colder, seasonable weather (as opposed to the 50’s of the last two days for example), and this should help push birds to feeders, warmer coastal and urban areas, etc.  Also, hopefully it will bring some snowfall to points north, as this year’s Goose Rarity Season has been lackluster, especially in the Greater Yarmouth Goose Fields.  A Greater White-fronted Goose that has been in Scarborough for a couple of weeks, and another in Berwick earlier in the month, along with a couple of Cackling Goose reports have been the only geese-of-note in southern Maine.  While “The County” saw single Barnacle and Pink-footed Goose in October, I have not had a single “good” goose in the fields of North Yarmouth, Cumberland, and Falmouth all season.  A Bean (!!!) Goose, Barnacle, and Pink-footed all in Nova   Scotia right now give me plenty of hope, and last year, things really didn’t pick up locally until mid-November anyway.  I will continue my thrice-weekly circuit.

So the short version of this is: go birding!  There are rarities out there to be discovered.

South Coastal Maine Rarity Roundup TEN!

BLPW,SheridanStreet,Portland,11-3-14
This Blackpoll Warbler was one of the record 9 species of warblers tallied on the day, and one of the top birds in my Portland territory. It was only the third time that this species was spotted by Rarity Roundup teams.

Each year on the first weekend of November, a group of us get together to scour the Southern Maine coast for vagrants, lingering migrants, pioneers, irruptive, and other seasonal highlights.  Coinciding with the peak of “Rarity Season,” we set out to use the geography of the Maine coast, coupled with knowledge of the best habitats and vagrant traps in order to find as many “good” birds as possible.  While this year failed to produce any “Megas,” we once again had a great day in the field, found lots of fun stuff, and enjoyed good food and beer at the Great Lost Bear at the end of the day (the real reason we all get together for this event!)

119 species were tallied by the 8 teams of the TENTH Annual South Coastal Maine Rarity Roundup, six species above our 10-year average, despite somewhat more limited coverage than in the past few years. The continuing “Audubon’s” Yellow-rumped Warbler was added to the cumulative checklist, while we also had our second-ever Snowy Egret, Prairie Warbler, and Nelson’s Sparrow.  Blackpoll Warbler and Clay-colored Sparrow appeared for the third time.

Most teams experienced a decidedly “birdy” day, especially from Portland through Scarborough.  A fallout of Dark-eyed Juncos, White-throated Sparrows, and Hermit Thrushes occurred with overnight northwesterly winds and a line of pre-dawn showers, with the fallout especially evident on the Portland Peninsula.  I’ll have more about the fallout on a blog entry later today.

Record high tallies were set for Pectoral Sandpiper (13), Northern Flicker (10), Carolina Wren (11), Hermit Thrush (52: the 26 in Portland alone was only one short of the previous all-time high), “Western” Palm Warbler (3), Chipping Sparrow (12), Field Sparrow (3; tie), and Lapland Longspur (37).  9 species of warblers was a new record as well, and Painted Turtle was added to our non-feather species list.  All but the longspurs can likely be explained by the unusually warm season to date.

Territory Highlights were as follows:

– Area 1, Kittery-York: Davis Finch.
1 NASHVILLE WARBLER, Legion Pond, Kittery.
1 Pine Warbler, Fort Foster.
1 PRAIRIE WARBLER, Fort Foster.
1 “AUDUBON’S” YELLOW-RUMPED WARBLER, Fort Foster.

– Area 2, Ogunquit/Kennebunport: Turk Duddy.
2 American Wigeon, Phillip’s Cove, Ogunquit.
1 Northern Pintail, Phillip’s Cove, Ogunquit.
1 Lesser Yellowlegs, Goose Rocks Beach.

– Area 3, Wells/Kennebunk: Doug Suitor, David Ladd, and Slade Moore.
2 Semipalmated Sandpipers, Webhannet Marsh
2 Gray Catbirds, Laudholm Farm.

– Area 4, Biddeford-Saco: Pat Moynahan, Marian Zimmerman, Joanne Stevens, et al.
1 NASHVILLE WARBLER, Saco Yacht Club.
1 CLAY-COLORED SPARROW, Timber Point.
1 NELSON’S SPARROW, Day’s Landing.
2 Lapland Longspurs, Day’s Landing.

– Area 5, Scarborough: Ed Hess, Noah Gibb, and Leon Mooney.
8 Great Egrets
1 SNOWY EGRET, Pelreco marsh
12 American Coots, Prout’s Pond.
8 LONG-BILLED DOWITCHERS, Eastern Road.
35 Lapland Longspurs

– Area 6, Cape Elizabeth: International Man of Mystery, Claudia, Robby Lambert.
2 “Western” Palm Warblers, private property
1 “Yellow” Palm Warbler, private property
1 DICKCISSEL, Higgin’s Beach.

– Area 7, South   Portland: John Berry and Gordon Smith.
1 Ring-necked Pheasant, Fort Williams Park.
1 Yellow-bellied Sapsucker, Calvary Cemetery.
1 Pine Warbler, Bug Light Park

– Area 8, Portland: Derek Lovitch and Kristen Lindquist; Jeannette Lovitch (Capisic and Evergreen); and a cameo by Doug Hitchcox.
2 Eastern Phoebes, Eastern Promenade.
1 BLUE-HEADED VIREO, Mercy Pond.
1 ORANGE-CROWNED WARBLER, Eastern Promenade.
1 BLACKPOLL WARBLER, Sheridan Street.
1 White-crowned Sparrow, West Commercial Street.

As usual, I exhaustively cover the Portland Peninsula and once again the most urban block in the state produced some great birds.  Kristen joined me for the second year in a row, while Jeannette (and Sasha) helped out with a few outlying patches.  Doug joined us just long enough to find the only White-crowned Sparrow of the entire day.  In addition to the goodies listed above, Kristen and I amassed 9 species of sparrows.

The fallout that I mentioned above was very evident in the morning, as we birded Portland’s East End. 150+ White-throated Sparrows and 100+ Song Sparrows littered the Eastern Promenade.  While Dark-eyed Juncos were fewer there, we encountered some big groups elsewhere, such as 60+ behind the East End School and 50+ in the lot on Sheridan Street, with 70+ later in the day in Western Cemetery. White-throats were everywhere: 50+ on Sheridan   Street for example.  And once again there was a decidedly disproportionate number of White-throated Sparrows in gardens and landscaping of downtown Portland.  A short loop from One City Center through Monument Square, behind Portland High, and back through Post Office Park yielded 35 White-throats, with the only other native migrant being 7 Hermit Thrushes.  Like the sparrow, Hermit Thrushes appear in a wildly disproportionate number to other migrants – especially all other thrushes – in downtown Portland.  I’m convinced that something causes White-throated Sparrows and Hermit Thrushes to either a) become disoriented by urban lights more often/more readily, especially under low ceilings (it was cloudy for most of the night and morning) or perhaps b) they simply don’t leave these lots in a morning flight as species such as Dark-eyed Juncos might.  In fact, I just read in an article in the Brown Alumni Magazine that a friend of the store dropped off about collisions in New York City that since 1997, more White-throated Sparrows have been found dead than any other species.  Coincidence?

Our sum of 26 Hermit Thrushes was truly amazing, as was our overall diversity on the day.  While the mild weather certainly has a lot to do with the number of lingering/pioneering birds that we, and other teams, encountered, the late-season fallout earlier in the morning certainly helped our cause.

Here are the overnight reflectivity and velocity images, with 10pm, 1am, and 4am once again used as an example.

At 10pm, there’s mostly rain in the area, but birds are mixed in.  By 1:00am, birds are on the move, as the rain has mostly moved into the Mid-Coast and offshore.  Birds were still on the go at 4:00am, as a narrow line of showers moved through the coast.  About an hour later, a steady rain developed (not shown) that continued until a short time before the 6:20 sunrise.  I believe this is why there were so many sparrows in and around the city come dawn.

In other words, it was another great day of birding in urban Portland in the heart of “Rarity Season!”

AUDUBON’S WARBLER at Fort Foster!

Yesterday, I had the pleasure of leading our annual “York County Rarity Roundup” Field Trip for York County Audubon today. With no rarities to “round up,” we set out to find our own, birding from Kittery through Wells.  We followed a very similar route to what Jeannette and I always do on our monthly south-coastal run.  The difference today was that with a group, and with so many birds at FortFoster, we never made it out of Kittery by lunchtime.  Too bad that meant we just HAD to have lunch at Loco Coco’s Taco (mmm, chili relleno burrito…)!

It was a very birdy day overall, even in the windy afternoon.  A preliminary total of 63 species of birds included 9 species of sparrows, 5 species of shorebirds, and 4 species of warblers.  Excellent-for-the-season bird diversity was augmented by 5 species of butterflies, 3 species of mammals, 2+ species of dragonfly, 1 reptile (Garter Snake), and 1 amphibian (Spring Peeper).

The bird of the day by far was “Audubon’s” Yellow-rumped Warbler that I found at FortFoster.  This western subspecies of Yellow-rump (it once was, and I believe will likely once again be considered a full species) has only occurred – or should I say, been detected – in Maine a few times.  I can only think of one recent record, an adult that nearly-overwintered at Dyer Point in Cape Elizabeth a few years ago.

If anyone wants to look for it, the bird was flycatching and occasionally eating Red Cedar berries along the west edge of the park. Follow the entrance road into the park, until the large gravel parking lot opens up on the left. The bird was loyal to the right (west) edge here, especially around the big cedars in the mowed lawn.

Noah Gibb and I photographed the bird extensively, and I was also able to borrow a phone to get a voice recording.  All aspects of the bird – from plumage to voice – fit perfectly with a pure “Audubon’s” Warbler.

I first glimpsed the bird sallying for insects in and out of shadows.  The overall extremely cool gray plumage tone – top to bottom – brought to mind a first fall female Pine Warbler. But something wasn’t right.  The bird began to call, and that was definitely not the call of a Pine Warbler…but what was it?  We saw the bird briefly a few times, the pieces began to come together, and then as it flew to another tree the bright yellow rump became evident.  “Audubon’s Warbler!!!!” I exclaimed.

DSC_0057_AUWA5,FortFoster,10-27-13

We studied the bird extensively for at least a half hour, occasionally in perfect light for prolonged periods.  I scribbled notes, and encouraged others to do the same before we discussed the bird any further.  Plenty of “Myrtle” Warblers (the Eastern subspecies of Yellow-rumped) were nearby for convenient comparison.

– Obvious “Yellow-rumped” Warbler with bright yellow rump, overall size and shape, bill size and shape, etc.
– Exceptionally cool gray overall plumage tone, not suggesting the brownish tones of even the palest Myrtles.
– Very diffuse streaking below.
– Very restricted and pale yellow “blobs” on sides of chest.
– Very subtle and restricted yellow on throat, not visible in all light conditions, but quite obvious in good sunlight.
– Lacked the extension of pale on the throat that “points” up around the back of the auriculars as on Myrtle.  Therefore, throat patch appeared rounded, or encircled by the cool gray of head.
– Auriculars only marginally darker than rest of head, often looking concolorous.
– Call note very different from surrounding Myrtles, much sharper and not as “blunt.”
– Exceptionally dull plumage highly suggestive of a first fall female, but the lack of a definite molt limit within the greater coverts prevents us from clinching the age. (reference: The Warbler Guide, Stephenson and Whittle, 2013)

Good bird!  And yes, Rarity Season is most definitely in full swing!  Good thing it appears that, after a prolonged drought, I have finally refound my rarity-finding mojo.  Phew.

Other highlights over the course of the full-day tour included the following:
– 1 pair Wood Ducks, Legion Pond, Kittery.
– Fort Foster: 1 “Western” Palm Warbler, 2 “Eastern” Palm Warblers, 6 Brant, 15 Hermit Thrushes, 1 Brown Thrasher, 1 Red-bellied Woodpecker, 2 Carolina Wrens, 32 Great Cormorants…
– Seapoint Beach, Kittery: 1 Saltmarsh Sparrow* (see photos and notes below), 1 Common Yellowthroat, 1 Eastern Towhee, 2 Long-tailed Ducks (FOF)…
– 1 Gray Catbird, Rte 103, Kittery.
– 1 Nashville Warbler (late), 1 Indigo Bunting (late), 2 Carolina Wrens, etc, Beach Plum Farm, Kittery.
– 24 Pectoral Sandpipers, 1 White-rumped Sandpiper, 3 Dunlin, 10+ Greater Yellowlegs, Harbor Road, Wells.
– 4 Semipalmated Plover (late), Community Park, Wells.

Now, about that Saltmarsh Sparrow – which I admittedly called an “Interior” Nelson’s Sparrow in the field…  Expecting to see an “Interior” Nelson’s Sparrow based on the timing, micro-habitat, and behavior, I reached for my camera before I fully studied the bird. After firing off some photos, and making sure everyone got on the bird, it took off and we never saw it again. Although I mentioned that the malar looked “quite dark,” I didn’t second-guess the call until I looked at photos on the computer this afternoon.  Yeah, it’s a Saltie.  The malar is not only dark and distinct, but it frames a clear white throat.  The breast streaking is dark and extensive, the bill has a fleshy-pink cast, and it is simply too long-billed for an “Interior” (subspecies alterus or nelsoni; I don’t believe they are identifiable in the field).  As a final clincher, note the fine streaks towards the rear half of the supercilium.  Behavior and timing wise: odd for a Saltmarsh.  Plumage: essentially textbook for a Saltmarsh.  Therefore, “After further review, the call (in) the field is overturned.”

My Last Good Flight of the Season at Sandy Point?

A strong, if relatively homogenous, flight passed over and through SandyPointBeach, Cousin’s Island, Yarmouth this morning.

7:03-9:00
39F, mostly clear, light-moderate but rapidly increasing W wind.

708 American Robins
88 Yellow-rumped Warblers
45 Dark-eyed Juncos
34 American Crows
22 Unidentified
8 American Goldfinches
7 Palm Warblers
6 Golden-crowned Kinglets
5 Savannah Sparrows
3 Hermit Thrushes
3 Ruby-crowned Kinglets
3 Chipping Sparrows
3 Rusty Blackbirds
2 Brown Creepers
2 Unidentified sparrows
1 Common Loon
1 Eastern Phoebe
1 Tufted Titmouse (they keep on coming this year)
1 American Pipit
1 AMERICAN REDSTART (very late)
1 White-throated Sparrow

Total = 945

I actually expected more juncos and especially White-throated Sparrows (at least in the parking lot, they almost never cross the water here), but the American Robin count was actually my third highest here.  The redstart, one of the first birds of the morning, was definitely unexpected – it has been several weeks since I have seen one.

Unlike Tuesday night into Wednesday, last night’s radar was unambiguous (I posted briefly about yesterday on the store’s Facebook page).  This was a solid late-season flight.  Here are the 10pm, 1am, and 4am reflectivity and velocity images for example.  You can see the rain mostly remaining well offshore.
a -10pm radar, 10-23-13 b - 10pm velocity, 10-23-13

c - 1am radar, 10-24-13 d - 1am velocity, 10-24-13

e - 4am radar, 10-24-13 f - 4am velocity, 10-24-13

So was this my last good flight at Sandy Point?  I sure hope not, but the calendar is getting late.  There’s no doubt there is still a big push of juncos at least.  But we’ll see if the weather conditions cooperate.

Meanwhile, as SandyPoint winds down, “Rarity Season” starts to pick up.  There’s our Bell’s Vireo in Harpswell, an Ash-throated Flycatcher on Monhegan, a Pink-footed Goose that was up in The County, and the usual smattering of fun fall stuff like a White-eyed Vireo or two, a couple of juvenile Red-headed Woodpeckers, and a sprinkling of “late” birds in no doubt partially due to the mild season.  I believe there are symptoms of Rarity Fever welling up inside me!

BELL’S VIREO in Harpswell!!!

Yesterday, Jeannette and I discovered a Bell’s Vireo on Abner Point Road, Bailey Island in Harpswell.  There are only three previous records of Bell’s Vireo for the state of Maine. 

In other words: MEGA!  And needless to say – especially since I missed the two from last year, despite my best efforts – this was a thrilling find, capping a very productive morning of birding Bailey Island that included a Yellow-breasted Chat (my first of the year) at Land’s End, and a total of 5 species of warblers on Bailey Island this am:  Hundreds of Yellow-rumps, and one each of Black-throated Blue, Black-and-white, Common Yellowthroat, and Blackpoll.  Song Sparrows, Dark-eyed Juncos, White-throated Sparrows, and other seasonal migrants made for a very birdy visit.

In what turned out to be our last stop of the morning, Jeannette and I walked Abner Point Road.  Upon reaching a promising thicket (see directions below), I began to pish.  Yellow-rumped Warblers and a Winter Wren responded immediately, and as Jeannette attempted to photograph the wren, I sorted through the yellow-rumps, hoping to find one with a yellow throat.  A handful of minutes later (about 10:35am), we heard a harsh, scolding chatter emanating from the dense vegetation.  “Vireo?” Jeannette asked quizzically as we both looked at each other, unsure of the sound – it sounded like nothing we are used to hearing.  I wondered out loud about a Carolina Wren making some odd sound (they’re good at that, and there was one in that particular thicket), and the nasal quality led me to consider a funky Red-breasted Nuthatch.  We looked hard but could not turn up anything that fit the sound.

About 5 minutes later, a small vireo pops out of the brush in front of me.  At first I called “White-eyed Vireo” due to the bright yellow flanks and overall shape, but then I got a clear look at the head.  “BELL’S VIREO!” I exclaimed, as Jeannette, a few yards away still working on photographing the wren rushed over.

As is often the case for Bell’s Vireos, it quickly ducked back into the cover.  I continued to pish, and the bird popped back up.  I had a second brief, but unobstructed view of the whole bird.  Jeannette went for the camera, and prepared to fire away, only to see the bird dive back into the shadows once again.  One last brief glimpse of the bird was all we would have for the next hour.

We searched hard, but could not relocate it.  A Blue-headed Vireo was more cooperative, and permitted us some comparison.  We listened to a recording of the call of a Bell’s, and there was no question in either of our minds’ that is what we had heard earlier.

We thought we heard that call in the distance of the thicket one more time, and perhaps even a snippet of a song, but background noise and an increasing southerly wind made us unsure of that.  And that wind was clearly not making this skulker any more likely to show itself.  At 11:50, we heard the distinctive call once again, but from thick shrubs behind a house across the street.  We hustled over, but unfortunately only managed to pish in a cat (one of at least five in this immediate area; it was worse than Monhegan!), which was likely the object of the vireo’s recent ire.  We worked the area as best as we could, and eventually saw the homeowner in her yard and received permission to wander around.  No luck.  We had also received permission earlier from the homeowner adjacent to the first thicket to check her yard, so we did another circuit, but we came up empty, and it was getting breezier and cloudier.  Lunchtime was calling us, too.

While I left with almost three pages of field notes, it was rather frustrating to not get a photo, especially since Jeannette was so close to snapping it!  However, as a firm believer in the value of written field notes for documentation of rare birds, I scrawled away in my notebook.  Here are the particulars, after seeing the entire bird well a couple of times, with notes entered in rough order of observation, not in order of relative importance (edited only for context, not content):

–  Overall relatively dully-marked, small vireo.  Body shape and size, and brief glimpse of the body color first suggestive of White-eyed Vireo, the expected rarity here.

– Fairly bright and extensive yellow on sides, from chest through undertail (suggestive of the Eastern subspecies?)

– Dull olive-gray back.  Dull greenish-gray wings.  Lack of contrast anywhere except the bright yellow of the flanks and undertail.

– One fairly bright whitish wingbar, on the tips of the greater coverts.  An indistinct second wing bar, presumably on the edges of the lesser coverts, was discernable, but did not stick out.  Not the bold, bright white double-wing bars like Blue-headed Vireo.

– Head grayish, perhaps with a hint of an olive cast.

– White or off-white throat contrasting with gray head and face and yellow on the rest of the underparts.

– Very dull face pattern consisting of a partial eye-ring (or perhaps best described as two eye-crescents) and indistinct supercilium restricted to in front of the eye.  Maybe a small hint of a supercilium a very short distance behind the eye, but I am unsure of this.  A darker line, or narrow smudge, through the eye gave a subtle hint of a face pattern reminiscent of a darker Warbling Vireo or very pale Philadelphia Vireo.

– Perhaps due to the angle, I though the bill looked relatively long compared to the size of the head, but it was clearly rather narrow for a vireo, and was diminutive compared to the Blue-headed Vireo observed a short time later.

– Relatively long-tailed (NOTE: although in comparing photos later, I wondered if it was actually suggestive of the shorter-tailed Eastern subspecies).

– The first view was of a “sleeker” or slimmer vireo, not the chunky, broad-chested shape of Blue-headed.

– Very active, and did not come out into the open for very long (NOTE: tail movement not seen, or not noticed, which could have been a good key for subspecies), always disappearing into low, dense brush.

In comparison to other species:
– Wingbars and bright yellow underparts distinguish it from Warbling Vireo.

– Lack of yellow in the throat and pale face pattern, along with wing bars and fairly long tail and slim shape help distinguish it from Philadelphia Vireo.

– Incomplete eye ring and lack of broad and bright yellow spectacles separate it from White-eyed Vireo.  Wings paler and less contrasty, and no contrasting pale gray nape as on WEVI.

Directions to the bird (although I have not heard any reports, positive, or negative, about the bird as of 4:00pm today):
To reach the thicket we first found it in, take Rte 24 from Cook’s Corner in Brunswick south through Orr’s Island and onto Bailey’s.  Make a right onto Abner Point Road at the Johnson Field Preserve.  Park on your left in the gravel parking lot for the beach.  Walk down Abner   Point Road a couple hundred yards, around the bend.  On the right, you’ll see a small parking lot with little white signs with people’s names on them.  The bird was in the thicket behind these signs, along with a Blue-headed Vireo and a mess of Yellow-rumps.

Sandy Point on 10/9, Goose Fields Redux, and More.

After three nights with little to no migration, birds took to the skies en masse come nightfall last night.  It was a big flight.  For examples, here are the 10pm, 1am, and 4am reflectivity and corresponding velocity images:
10pm radar, 10-8-1310pm velocity, 10-8-13
1am radar, 10-9-13 1am velocity, 10-9-13 4am radar, 10-9-13 4am velocity, 10-9-13

That’s a heckuva flight!  But as October goes on, more and more of the migrants are sparrows. Most sparrows (juncos and Chipping Sparrows are the exceptions) do not partake – or barely so – in the morning re-determined migration (“morning flight”), at least at Sandy Point, so I have been disappointed with the tally come dawn at Sandy Point on more than one occasion in mid-October.  While this morning’s flight was still good, it was not as busy as I would have expected based on the density of those radar returns.  But there were a lot more sparrows around in the bushes at Sandy Point and elsewhere this morning; I wonder what percentage of last night’s flight were White-throated Sparrows?

At the bridge at Sandy Point, the morning’s flight started out quite slow.  By 7:30, I had even considered packing it in and going to look for sparrows.  But then things picked up a little bit, and a steady trickle of birds slowly added up to a respectable tally.  Both kinglets spent a lot of time swirling around the point this morning (as usual, I was conservative in my count of how many were actually crossing, as many would turn around, come back, and try again), and the sparrow tally was probably a lot higher.  However, by the time I left the bridge, most White-throats had already dispersed into the woods.  Song Sparrows – which I do not attempt to tally due the number of breeding birds in the powerline cut – were definitely more abundant than they have been as well.

Here’s the scorecard:
6:45-9:15

Afterwards, I did a circuit of the local “goose fields.” As with everywhere to our south, the resident, non-migratory population of Canada Geese is burgeoning in southern Maine.  This resident population begins to coalesce in the fields of Yarmouth, Cumberland, and Falmouth in early August, and by the middle to end of September, the flock includes a sizeable percentage of the local breeders.  The percentage of local breeders that are in the fields on any given day increases with the onset of early Canada Goose hunting season in early September.

This year, the number of geese among all fields has varied between 200-300 total birds since early September. This number of pre-migrant birds has grown steadily over the past five years in particular.  This week, the first real influx of geese arrived, presumably from some points north.  It is the flock of resident geese that know the safe fields (no hunting, less Bald Eagle activity) and travel corridors to and from the bay where they roost that attract the migrants, including those occasional rarities.

My high count this week of 445 Canada Geese today was my highest tally since the spring.  A couple of Eastern Meadowlarks and up to 8 Killdeer were also present at Thornhurst Farm this week, and Eastern Bluebirds have been rather widespread. A Pied-billed Grebe was once again in the pond on Woodville Road in Falmouth, as is often the case at this time of year.

The goose numbers and the chance for finding rarities should only increase (well, with various ebbs and flows) from now through the first heavy snow.  In fact, I often find my first “good” goose in the second week of October.  It’s also primetime for sparrows.  And this is why I hate leaving the state in October, but once again, I am off!

Early tomorrow morning I depart for Iowa, where I will be speaking at the Iowa Ornithologist Union’s Fall Meeting.  I’ll be giving the keynote presentation on “How to Be a Better Birder” using my SandyPoint case study program and I will also be showing my Russian Far East travelogue.  Finally, I will be joining the 2009 Bradbury Mountain Hawkcounter, Danny Akers, in leading a field trip.

After my weekend in the Hawkeye State, I head to Wisconsin to visit the Urban Ecology Center in Wisconsin.  In between and thereafter, I’ll be spending a couple of days birding and visiting with friends.   I’ll post the occasional update about migration in the Midwest, my birding, and other musings on my book’s Facebook page should you be interested in following my travels.

Now I am just left to wonder what state bird I will miss here in Maine while I am away (there’s always one!)

Black Skimmer at Sandy Point!

Well, I sure wasn’t expecting this on my Sandy Point Patch List!
DSC_0021_BLSK1,SandyPoint,10-4-13
Black Skimmer, SandyPoint #180!

An otherwise slow morning flight (more on that shortly) was interrupted by an odd call emanating from upriver of the bridge. “Hmm, sounds like a Black Skimmer, I thought.”  Uh, wait…but alas, there it was!  It alighted on what was left of a small sandbar with a couple of gulls, and as that sandbar became inundated, it took to the wing again and began to forage.  I lost sight of it as it moved up the bay, but a little pocket of Palm Warblers moving through distracted me.

Looking at the radar last night, the flight seemed strong, but the Morning Flight was decidedly slow.  Here are the 1am radar and velocity images for example:
1am radar, 10-4-13 1am velocity, 10-4-13

A couple of things are noticeable.  For one there’s the fairly narrow diameter of the flight reflection which would suggest a low flight (the radar beams well out from the tower are above the height of birds; the “angle of elevation).  This definitely happens when birds, such as sparrows – and they’re definitely on the move right now – which tend to fly relatively low dominate the flight.  So perhaps a lot of the flight last night was of the sparrow variety.

However, the velocity image suggests the north to south motion was rather slow.  Perhaps it was just because it was so calm and slower-flying migrants were in the air and therefore were making less progress (ground speed).  Or maybe there’s a lot of dust and bugs up there; it has been warm and dry after all.

Regardless of the explanation, or lack thereof, the flight was slow.  But did I mention I had a Black Skimmer?

– 6:38-8:20

Afterwards, I decided to check on my “lots of sparrows moving last night” hypothesis, so I visited Old Town House Park.  There were an ample amount of sparrows (30+ Song, 20+ Swamp, a small number of White-throated, 2 Lincoln’s, 1 Savannah, and 1 White-crowned), but not enough to conclude much about the composition of last night’s flight, or lack there of.  But it was pleasantly birdy, with a nice sprinkling of other migrants, including 11 Eastern Bluebirds, 2 Pine Warblers, and the first Purple Finch that I have had in a couple of weeks.

Meanwhile, in the goose fields, things have not yet begun to heat up.  While there may be some bona fide migrants around, my tally of 283 Canada Geese today fits right there within the 200-300 that have been present since late August, when the local resident birds began to flock up post-breeding.  This will change soon.

Yet Another Great Morning Flight at Sandy Point!

k -DSC_0024_PIWO,SandyPoint,9-26-13
I do love it when the big ones fly by, especially on mornings like this.  They’re easier to identify and tally…especially when they are Pileated Woodpeckers!

It’s also nice when more birds pause in the trees at the point, allowing for identification as a “sample” of what’s going overhead.  It’s especially nice when they land in front of my face…like this Philadelphia Vireo did.  If only there weren’t a few twigs between us!
i -DSC_0008_PHVI,SandyPoint,9-26-13

I usually leave the bridge before raptors begin to get going, but today, I was treated to an early-morning Peregrine Falcon flight.  A couple of the birds didn’t even blink and eye and kept going.  Others terrorized migrant flickers.
j -DSC_0017_PEFA,SandyPoint,9-26-13

Normally, I start off with the overnight radar analysis to describe why there were (or were not) so many birds come morning.  But today, let’s cut to the chase and get right to the numbers:

Total= 3523 (*third highest total)

So there you have it.  Wow.  <Insert various superlatives and/or swear words>   I just wish I could have whittled down that unidentified total a little bit more – who knows how many single-species records I might have set?

There were two reasons the unidentified tally was so high.  One is that early-morning cloud cover once again reduced many of the birds to silhouettes.  Secondly, the intensity of the first two hours of the flight was really exceptional.  On multiple occasions, I could do nothing more than step back look up, smile, and click off a cloud of unidentified warblers – no point of even lifting the binoculars.  Bunches of birds high overhead; I’d follow one bird into the Magic Elm, and 20 would shoot out.  Birds were sneaking below me.   It was, at times, a bit overwhelming!  But it was also exceedingly fun; I like the challenge, and since my interest lies in quantifying the flight as much as identifying the composition of it, the high unidentified tally only bothers me a little…OK, maybe a little more than a little, but anyway…

I couldn’t resist taking a few photos, such as the Philadelphia Vireo landing in front of me, or the majestic Pileated Woodpecker cruising by.  16 species of warblers, a bunch of new records and near-records, and some “good” birds.  Yeah, that’s a good flight.  But I actually think my highlight was one little female American Redstart.  She dropped in from high overhead, straight down into the regenerating cherry that stands directly in front of me (and perfectly blocks the sun from my eyes for the first hour of the day) – the one the Philly V was in – and hopped her way to the near edge.  She looked at me, and cocked her head to look at the camera lens that was lying down next to me.  I am guessing she saw her reflection.  She looked at me, chirped in a gentle contact call – not the harsh alarm call or even the sharp flight call – and then hopped back into the brush.  We had a moment.  I enjoyed that.

OK, back to business…the radar.  Save these images for future reference.  This is what “GO BIRDING IN THE MORNING!!!” looks like.  Here are the 10pm, 12am, 2am, and 4am radar and velocity images for example <insert “boom” sound>:
a-10pm radar, 9-26-13 b -10pm velocity, 9-26-13 c -12am radar, 9-27-13 d -12am velocity, 9-27-13 e -2am radar, 9-26-13 f -2am velocity, 9-26-13 g -4am radar, 9-26-13 h -4am velocity, 9-26-13

Even at 6:00am, with light more than peaking into the eastern sky, birds were still on the move.  If I had not expected to go to SandyPoint for sunrise this morning, and I had seen this image, I would have flown out the door.
6am radar, 9-26-13 6am velocity, 9-26-13

When there are this many birds in the air so close to sunrise, there are going to be a lot of birds taking part in the “morning redetermined migration” come dawn, along with crepuscular migrants that are moving in the early light.  The radar provided all of the suggestions of a big flight.  And, with a light northwesterly breeze, many more birds were low and in the trees than on the westerly breezes of the last few mornings.  Here’s the wind map, showing that low moving off of the Maritimes, ushering in a north to northwesterly flow behind it – as I postulated on my blog yesterday.
wind map, 9-25-13

While I am rarely even at Sandy Point for four days in a row, it is exceedingly rare that the fourth day would be so busy.  But I think that upper level low finally pulling out of the way re-opened the floodgates.  And it looks like tomorrow should be good as well, continuing a most impressive string of good flight nights.  But I will give my neck a break tomorrow from staring straight up and spinning back and forth at Sandy Point.  Instead, I’ll just have to see what the flight will be like with my tour on Monhegan Island.  Yeah, I know, tough life.

On Sandy Point, Winter Finches, and Portland’s Congress Square Park

I’ve spent each of the last three mornings at Sandy Point, and it is a rare treat indeed (but not for my neck!) that the winds tonight will likely be conducive to yet another morning in my “other office.”  Yesterday’s moderate flight produced two Patch Birds: Western Kingbird and Gray-cheeked Thrush while today’s better than expected flight yielded 15 species of warblers.  (Tallies from both days are on our store’s Facebook Page as always).

While I can’t believe there are more Northern Parulas left to migrate through, I am optimistic about tomorrow morning.  The upper-level low spinning over Atlantic Canada that has produced rain to our northeast and the clouds overhead that have reduced the flight – and my ability to identify it! – is expected to move out, and I wonder if that will open up another wave of birds to head south from that region.  It is exceedingly rare for me to have four days in a row of good Morning Flights at Sandy Point, so I look forward to another early start tomorrow.

With each passing flight, the changing season is becoming more obvious.  Fewer early warblers and growing numbers of Yellow-rumps and sparrows, for example.  And of course, as a season progresses, we birders often think ahead to the next season.  The near-complete dearth of Red-breasted Nuthatches, Purple Finches, and Pine Siskins (zero) that have passed SandyPoint is an early indicator that it will be an “off” winter for northern finches as expected.  Few Blue Jays and Black-capped Chickadees passing through also suggest an abundance of food to our north.

These observations reflect what I am seeing elsewhere in Maine, and reflect the information contained in this year’s “Winter Finch Forecast” by Ron Pittaway that just came out this week.  This venerable resource is posted each fall, and reflects a lot of effort by the author to bring together various tidbits of information.  Its arrival each fall is highly anticipated – even if it does not portend the arrival of lots of highly anticipated finches.

But today, I wanted to take a moment to discuss one of the local issues that we have decided to wade into.  As most Portland – at least – residents may know, there is a proposal to transfer a portion of Congress Square Park to private development for a conference center.  The city needs a conference center, and the park needs some attention.  I’ll leave it to the residents of Portland to weigh the costs and benefits of this particular plan, but one aspect that concerns me greatly is the current blueprints that show a massive glass wall facing a smaller park with limited vegetation.

Here’s a link to what I believe to be the most recent development proposal; I don’t think any significant updates have been made.  Jeannette and I believe that we can use our store as a vehicle to promote bird conservation, and although we certainly don’t stick our nose into every project, sometimes we feel that we need to be the voice for birds, birding, and bird conservation.  Capisic Pond Park, the Eastern Promenade, Sandy Point, and now development at the fringes of Florida Lake have been projects we have worked on.  While we may not go too much further with our efforts in this case, we thought it was best to offer expertise to point out a potential issue with this projects design.  I have sent this letter to city officials and the new group, Friends of Congress Square Park.  I post it here for your information, and if anyone has suggestions on whom else to send this to, don’t hesitate to let us know.

RE: Congress Square Redevelopment plans

To whom it may concern:

I am writing you today not to take a stand for or against the current proposal at this time, but instead to bring to your attention a couple of aspects of urban parks, construction, and wildlife interactions that has raised a significant amount of concern with me.

First, a little bit of background.  Migrating birds that stream over Portland every spring and fall face a myriad of risks.  Many of our favorite songbirds, such as warblers, orioles, and tanagers all fly at night.  For reasons unknown – likely due to the use of stars for navigation – birds can become disoriented by lights.  Lights on communication towers, lights on buildings, lights at stadiums, lights left on in office buildings, and even lights in people’s homes.  Especially on cloudy and foggy nights, birds will be drawn to this artificial lighting, and many will meet an untimely death as they collide with structures or even drop dead from exhaustion as their bodies metabolize their muscles in order to fuel the last gasps of flight as the bird circles, and circles, and circles, confused by the light, drawn in by its grasp.  The cumulative light pollution of cities, towns, and even single-family homes, results in perhaps hundreds of millions of deaths of migrating birds each year.

However, not every bird disoriented by city lights will die.  Some find refuge in a well-landscaped park and find enough food to survive, refuel, and eventually move on. Most others find just enough refuge to move on come sunrise, when the direction of the sunrise and visual landmarks can usher a bird in the right direction.  In order to avoid predators, many of these birds will fly low through the city streets, dropping in to the next tree, the next park, or even the next garden as these birds – in what is termed “redetermined migration” attempt to correct for the errors of their ways overnight.  These errors could result from disorientation from lights, “groundings” from severe weather, or even from drifting too far on strong winds behind a cold front.

Especially for those birds exhausted from their travels or their disorientation, every single tree in an urban environment can be a life-saver.  A place to rest, a place to forage for just a little food or at the very least a place to avoid predators.  Working from some part of the city, the birds will work their way inland (in the case of a coastal city such as Portland) looking for more extensive habitat where they can refuel.

I have watched flocks of White-throated Sparrows winging it down side streets, landing in potted plants at the first sight of a possible threat.  I’ve seen an American Woodcock walking down a sidewalk near Monument Square.  I have seen waves of Blackpoll Warblers streaking by just over the treetops of Deering Oaks Park.

As the birds work their way to quality habitat, such as Evergreen Cemetery, many of these birds are more than strong enough to avoid predators, avoid traffic, and fly at full speed over the course of the first couple of hours of daylight.

Thud.

The migrant lays still on the sidewalk; dead.    It has hit a window.

It has flown hundreds of miles from the forests of Canada.  It has survived ever-changing weather, dodged hawks at every turn, and found enough food to pack on enough fat to fuel an epic journey to the rainforests of South America for the winter.   A shift in the wind the prior night resulted in foggy conditions as it arrived in the airspace over Portland.  Attempting to orient itself, it circles the red blinking light on the top of a building until it is too tired.  But this bird is lucky.  Below this building there is a small park with a handful of trees.  Good enough, and the bird alights.  The sun rises, and the bird, not finding much food in a few ornamental plantings, decides to head further inland.

Flying from tree to tree, the bird sees the next tree just ahead.  But that tree was only a reflection in glass.  Its journey ends.

Glass kills as many as 1 billion birds per year in North America. Urban light pollution may kill as many as 31 million birds per year.  Lighted communication towers may kill upwards of 100 million.  Only free-roaming cats are estimated to kill more birds per year than any of these other anthropogenic causes.  You can see why glass in lighted urban areas is such a problem.

The current proposal for a new Event Center in what is now Congress Square Park includes a massive glass façade, with “doors” that open, putting glass walls out at multiple angles.  All of this glass will be reflective.  Architects and admirers like that about glass.  But whatever trees remain will be reflected by that glass.

Thud.  Another migrant is dead.  How many dead birds will people pick up on the sidewalk before anyone takes notice?  Or will the rats clean up the mess before the morning rush?

Is the new CongressSquareEventCenter going to be a death trap for exhausted and confused migrants?  Probably.  Can this risk be minimized or avoided?  Yes.  Does anyone care?  That, to me, is always the toughest question.

But there are solutions out there.  There are treatments that make glass less-reflective, or ways to break up the reflection so birds will not be drawn to it.  Glass can be positioned to reflect the ground, and trees can be positioned to minimize reflection.  There are certainly plenty of materials that don’t cast a reflection as well.  There are even city-wide efforts to reduce bird collisions that range from lighting standards to simple programs to get people to turn off the lights as they leave their office for the night.

My only goal with this letter is to raise awareness about a significant problem, but one that might well be avoided.

For the sake of brevity – I think you will agree that this letter is long enough already – I will simply point you towards two sources for more information, from background to solutions.  The first is the “Birds and Collisions” page from the American Bird Conservancy: http://www.abcbirds.org/abcprograms/policy/collisions/glass.html

The second is the home page of the Fatal Light Awareness Program: http://www.flap.org/

I sincerely hope that you will recognize my concerns and take them under consideration.  I would be happy to offer more first-hand observations to describe why this issue is real in Portland, and why a glass façade facing some of the few trees that exist in the center of an urban area could result in significant avian mortality.

I thank you for your time and consideration.

Sincerely,
