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:

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
39F, light NNW to calm, partly cloudy to clear

323 Yellow-rumped Warblers
105 Ruby-crowned Kinglets
71 Unidentified

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!

Yet Another Great Morning Flight at Sandy Point!

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

2 Replies

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,

Derek Lovitch

Huge Morning Flight at Sandy Point!

My last blog entry ended with a little bit of foreshadowing, did it not? But before we get to Sandy Point this morning, let us take a moment to review the radar images from the weekend for comparison.

This is the 12:00am image from Sunday. This is what “no migration” looks like on the radar. You can also see the rain approaching from the west.

Now this is the midnight image from Saturday. This is what “I have no idea what’s going on” looks like on the radar. While anything from some weird warping of the radar beams from changes in air temperature to a simple malfunction could result in this, what it is NOT is a lot of birds. It’s too irregular…and bird’s don’t “explode” in narrow bands!

So, compare those to what “a whole boatload” of birds looks like. Here are the 10pm, 12am, 2am, and 4am base reflectivity and velocity images from last night.

Yeah, it would have been nice to be on Monhegan this morning. But I was in my other sanctuary – my office at Sandy Point. And this is what happened:

6:28 – 10:05am.
43F, increasing W to NW, clear.

1338 Unidentifed (*2^nd highest)
416 Northern Parulas (* Seriously, how are there any more parulas to come through! This is the second highest count of all time, and now all three of the highest tallies are from this year!)
281 Northern Flickers
179 Black-throated Green Warblers (*2^nd highest)
163 Blackpoll Warblers
91 Yellow-rumped Warblers
43 Black-and-white Warblers (*record high)
39 Red-eyed Vireos
35 American Redstarts
29 Blue Jays
29 Ruby-crowned Kinglets
23 Yellow Warblers
22 Blue-headed Vireos
21 Scarlet Tanagers (*record high)
21 Dark-eyed Juncos
19 Cedar Waxwings
18 Magnolia Warblers
17 Nashville Warblers (*record high)
17 American Goldfinches
13 Black-throated Blue Warblers
12 Eastern Phoebes (* ties high)
11 Swainson’s Thrushes
9 Palm Warblers
6 Rusty Blackbirds
5 American Robins
4 Unidentified vireos
4 Chestnut-sided Warblers
4 White-throated Sparrows
3 Least Flycatchers
3 Cape May Warblers
3 Bay-breasted Warblers
2 Common Loons
2 Broad-winged Hawks
2 TUFTED TITMICE (rarely seen crossing)
2 Unidentified thrushes
2 Golden-crowned Kinglets
2 Blackburnian Warblers
2 Common Yellowthroats
1 Osprey
1 American Kestrels
1 Yellow-bellied Sapsucker
1 Eastern Wood-Pewee
1 Common Raven
1 Philadelphia Vireos
1 Veery
1 Tennessee Warbler
1 CONNECTICUT WARBLER (My third of the season here; it’s the fall of the CONWs in Maine!)
1 Northern Waterthrushes
1 Rose-breasted Grosbeak
1 DICKCISSEL (third of the season here)
1 Baltimore Oriole

Total = 2, 905 (4^th highest tally all time for me)

Some of the migrants pause long enough at Sandy Point to do a little snacking. Here’s a Red-eyed Vireo eating Alternate-leafed Dogwood fruits, and a Swainson’s Thrush stepping out into the sun to dine on Winterberries.

A little post-Sandy Point birding yielded two Wilson’s Snipe trying to stay hidden along the edge of a puddle along Greely Road in Cumberland.

And tonight looks just as good…perhaps even a little better with a more northwesterly flow. See ya at the bridge at sunrise!

Monhegan Island, 9/20-22/2013

1 Reply

On a morning with a big overnight migration in the fall, there’s no where I’d rather be than SandyPoint. I just wish there was a direct ferry from there right to MonheganIsland. Any other time, I would just rather be on Monhegan.

While our annual MonhegZEN Fall Migration Weekend coming up this weekend (still some space available), Jeannette and I headed to the island Friday through Sunday for a few days of birding and visiting with friends. It was kinda odd being there without a group! Not surprisingly, I did not bird much less hard.

I’ll post some radar images from the weekend on a forthcoming blog entry that I hope to post by day’s end. A decent flight Thursday night into Friday produced a fair amount of birds on the island, even after our late (relatively speaking) arrival at 10:00am, and even though it seemed – as is often the case on calm mornings – birds that arrived at dawn continued on to the mainland. Three of our first handful of species, however, were Philadelphia Vireo, Cape May Warbler, and Yellow-billed Cuckoo. Welcome (back) to Monhegan.

The birding improved in the afternoon, highlighted by a Western Kingbird.

A Lark Sparrow and two Dickcissels – all present for a few days – were enjoyed (here, one of the Dickcissels with the Lark Sparrow and a White-throated Sparrow in the background). Typical “Monhegan Trash Birds:” birds that are noteworthy anywhere else in the state but are fully expected in an autumn visit here.

We ended up with 67 species of birds on the day, including 11 species of warblers. Yup, a slow day of birding on Monhegan beats a good day of birding almost anywhere else. Light southerly winds that developed over the course of the day became calm by nightfall, and call notes early in the night were suggestive of birds departing the island.

With a southerly flow aloft, I didn’t have high hopes of a lot of new arrivals for the next morning. The radar image was, simply put, was weird – some sort of temperature anomaly or perhaps a malfunction, so I couldn’t use that to confirm or alleviate my concerns. A mere handful of bird overhead at dawn on Saturday morning confirmed it though – there was not much on the move overnight.

Fog rolled in and out for most of the morning, clearing out in the afternoon on an increasing south to southwesterly breeze. We beat the bush hard, and covered a lot of ground, but birds were hard to come by. There were quite a few more Yellow-rumped Warblers around than on previous mornings, Kristen noted, and we added plenty of species to our trip list over the course of the day. While the Dickcissels apparently departed, the Lark Sparrow continued, and the island was now up to three Clay-colored Sparrows.

Clay-colored Sparrows, Dickcissels, and Lark Sparrow, check: the triumvirate of Midwestern regular-rarities out here. Two adult Lesser Black-backed Gulls, a tarrying Eastern Kingbird, a Semipalmated Plover, and a good afternoon Northern Gannet show were the other highlights of what amounted to be an exceptionally slow day of birding for Monhegan in the fall. Nevertheless, complaints were not uttered – we were on Monhegan! – and besides, I got to mooch a TV (Thanks Paul and Sue!) to watch Rutgers come from behind to defeat Arkansas in an exciting finish, and we visited the Monhegan Brewing Company. Yup, tough day.

This young Peregrine Falcon – with a bulging crop from its last meal – also had a good day.

Unfortunately, an increasing southerly wind overnight precluded much in the way of any migration. Take a look at the next blog to see what “almost nothing” looks like on a radar image. Clouds were thick by dawn, too, but the rain held off until after breakfast. After another fulfilling and scrumptious breakfast at the Trailing Yew, Jeannette, Kristen, and I headed down to Lobster Cove for a bit of seawatching. We could see the wall of rain on the radar, and we could now see it on the horizon. But as it marched closer, tubenoses joined the gannets. In a mere 15 minutes or so, 20+ Great Shearwaters and 6+ Sooty Shearwaters zoomed through my scope. And then the skies opened up. This is what a line of rain – ahead of a cold front – looks like on the radar.

The southerly winds were diminishing as the rain tapered off rather quickly over the course of the morning, but seawatching was less productive before lunchtime – apparently those tubenoses were all on the move just ahead of the precipitation. But with the sun beginning to peak out after lunch, at least more birds were more visible again: two of the Clay-colored Sparrows, a Philly Vireo, etc. Joined by Paul and Doug, we encountered a – or the – Yellow-billed Cuckoo, and then a calling flyover Lesser Yellowlegs became my 202^nd species on Monhegan.

Moments later, Paul spotted a night-heron in a narrow drainage, and Doug soon relocated it. A juvenile Yellow-crowned Night-Heron! Once a more regular bird in Maine, and even on Monhegan, it had been about a decade since one had made an appearance on the island. But this bird showed up a couple of weeks ago, and was often seen foraging on grasshoppers in lawns. Rumors of its continued presence were circulated, but there were no confirmed sightings for over a week. Until today.

Monhegan bird #203! And two island birds in about 10 minutes. Now that’s the way to finish strong.

When it was time to go, we were very happy to see the waves were rapidly dropping off. Seven foot seas this morning had been reduced to 3-4 at most as we hopped on the Hardy Boat for the trip back. A Great Cormorant on the Outer Ducks was our 88^th species for the Monhegan tally for this trip, but 88 –including a mere 13 species of warblers – was a fairly low total for three days out here at this time of year. That being said, it could have been much lower had we not continued to beat the bush.

Two juvenile Lesser Black-backed Gulls joined some hopeful Herring Gulls following the boat to shore, and westerly winds were increasing as the cold front pushed through. There would no doubt be a lot of new birds come morning on Monhegan. While I would be sorry to miss them, I knew fun was going to be had at SandyPoint, so I was not upset.

And I was right…

Two Fun Mornings at Sandy Point

With a busy tour and travel schedule once again this fall (every year I say I will schedule fewer things in my favorite season to bird in Maine!), my time at Sandy Point is at a premium. Since it takes certain conditions to make birding here worthwhile, I get quite excited when conditions line up for a good flight.

I was very anxious to arrive at “my office” on Tuesday morning. Moderate northerly winds overnight turned to the northwest, resulting in an exceptional flight over and through SandyPointBeach come dawn. Here is the morning’s scorecard:

Simply put: wow! That was one heck of a flight. In fact, it was downright overwhelming at times – flocks of flickers, waves of warblers, packs of waxwings. It was almost too much to count, and thankfully, Jenny Howard agreed (OK, so maybe I didn’t exactly ask, but beg) to tally flickers for the busiest part of the morning for me. That helped a whole lot.

After a flood like yesterday morning, I am not disappointed by the slow, but steady trickle through the point this morning. It was a more manageable number to count, with quite a few birds lower than yesterday, and often only a few at a time; it was easier to sort through.

Here’s this morning’s scorecard, then, we’ll compare the different flights as viewed on the radar.

I’ll admit, I wasn’t expecting it to be quite this good. And despite really only a “good” flight, parulas had their second highest tally – I didn’t think there would be any left after yesterday’s flight! And yes, this more manageable flight was more “enjoyable,” if considerably less awe-inspiring.

So, what made me have lower expectations for today? Let’s go to the radar!

First, the massive flight overnight Monday into Tuesday that led to all of the records yesterday. I have included the 10pm, 12am, 2am, and 4am radar and velocity images:

Combined, these images show a very strong flight all night long, with a lot of birds offshore come twilight, and likely a lot of birds arriving at the coast come dawn. Looking at that image when I went to bed, and when I awoke, coupled with the light northwesterly winds all night left no doubt that things would be hopping at Sandy Point. And, as we now know, there most certainly was. If you see a radar image that looks like this – go birding in the morning!

In fact, it was a good day all-around for migrants, and everywhere we looked up yesterday, raptors were on the move.

Now, let’s take a look a the radar and velocity images from 10pm, 12am, 2am, and 4am last night:

As night fell Tuesday night, clear and mostly calm conditions let birds take to the air once again – but not nearly as many as the night before. Notice how much smaller the area of return is, and how much less dense? Meanwhile, the velocity image was much less distinctly fast-moving, north-to-south as the previous night (of course, with little to no wind, the ground speed of the birds would be less anyway) – a little more ambiguous than the night before. Furthermore, with a forecast for westerly winds (not as good as northwesterly), and the chance that they would become southwesterly by dawn, I did consider skipping Sandy Point this morning, but with the rest of the week looking even less productive, I knew I had to give it a go.

And, obviously, I am glad that I did. But upon returning to the store, and checking those above radar images once again, I find it a bit odd that the radar image (small in diameter, but very dense) did not translate to a more distinct velocity image. Perhaps there was a lot of slow-moving stuff up there (insects, pollen, dust, etc) that clouded the motion of the birds. Either way, it was a good night for flying, and if it’s a good night for flying, it’s a good morning to be at Sandy Point!

Yesterday’s record high temperatures (92 in Portland shattered the old record of 87) were ushered in on a strong southwesterly flow. Unseasonably warm air continues today, as the southwesterly winds aloft are picking up ahead of tonight’s cold front (more on that shortly).

Here are the continental wind maps from yesterday afternoon, and this afternoon. Yesterday, you can see the south-southwesterly flow originating from under a broad area of high pressure over the Southeast…

…but notice that by today, cool, Canadian air was pouring down into the Upper Midwest (which resulted in some big flights over the last two nights in that region).

In addition to hot and very muggy conditions, this strong southerly flow has the potential to usher in some hot new rarities to our neck of the woods. While it appears that the Biddeford Pool Kentucky Warbler has moved on, I am expecting some more southern strays to turn up in our region. Keep in mind, however, that these winds are not “blowing” birds north, but instead facilitating birds to arrive here that are either wandering (post-breeding dispersal, prospecting for new territories, etc) or area already flying in the wrong direction (e.g. “180-degree misorientation”).

In other words, if a Kentucky Warbler – for example – was “miswired” and began to fly north instead of south, a strong southerly wind would push it even farther the “wrong” way. Then, with tonight’s cold front, the strong northwesterly winds that follow could push the birds towards the coast. There, they find a coastal migrant trap – i.e. a dense thicket full of fruiting bushes in the woods of Biddeford Pool – to seek shelter in while they refuel. There, they are more likely to be found by an alert birder than say somewhere in the valleys of the western Maine mountains. Many migrants spend 3 to 7 days to “refuel.” I don’t think it was a coincidence that the Biddeford Pool KEWA was seen for five days…and that it disappeared after a night of light southerly winds. Of course, it may have just moved to a richer food patch, or one without birders unnecessarily blasting a tape at it all afternoon.

Anyway, what will the weekend produce? I might be thinking more along the lines of birds like Summer Tanagers and Hooded Warblers based on this recent weather pattern. Unfortunately, I won’t be around to find them! Instead, I will be helping out at the Leica Sports Optics booth at the Cape Cod Birding Festival in Hyannis (I’ll also be signing copies of “How to Be a Better Birder,” which of course covers many of the vagrant-producing and Mega-finding topics that I have touched upon here).

Ahead of tonight’s cold front, and before the forecasted thunderstorms of the afternoon, I – not surprisingly – was out birding this morning. It’s September – there’s really no such thing as a night with “no” migration. However, what was flying last night was not being noticed on the radar; likely a limited number of birds were flying below the clouds, however.

Here’s the midnight radar image for example:

That would be thunderstorms. Not birds. And we can verify it from the velocity image:

…A distinct west to east movement, unlike the northerly to southerly movement of southbound fall migrant birds. Therefore, I was not surprised to have very, very few birds overhead at dawn over our yard this morning, or later on at Hedgehog Mountain Park. I did, however, find a lot of birds in the woods. While some of these might have been new arrivals that snuck in below the clouds and between the storms, the mixed-species foraging flocks working through the woods was much more indicative of birds that have been around for a day or two. The flock that moved through our yard shortly after sunrise, consisting mostly of Blackpoll Warblers, also contained not one, but two new Yard Birds for us: Cape May Warbler and Philadelphia Vireo! Also, at least two Tennessee Warblers.

Multiple mixed flocks were encountered at The Hog, led by Blackpoll Warblers, along with a healthy serving of Black-throated Greens. A Lincoln’s Sparrow foraged at the edge, and a mixed-species flock consisting of 40+ Chipping Sparrows, 6 Eastern Bluebirds, and 1 Pine Warbler worked the edge of the transfer station and out through the ballfields.

Afterwards, I zipped down to Pine Point for the low tide. Shorebird numbers are down considerably, as expected by the middle of September. And, I would expect a lot of the birds I saw today to clear out behind this next cold front. About 180 Semipalmated Sandpipers led the way, punctuated by a juvenile Red Knot, and two continuing American Oystercatchers (they were too far to determine age, visible over on Western Beach as viewed from Pine Point Beach). Four juvenile Dunlins were a sign that their migration – one of our two latest migrant shorebirds – is just now picking up. The highlight, however, were side-by-side “Eastern” and “Western” Willets. Unfortunately, I was only able to get the two in the frame together by phone-scoping, here with a Greater Yellowlegs for a convenient reference.

I then carefully approached with my “real” camera, but I never again saw the two birds in the same field of view. However, I did get solid photos of both the juvenile Western…

…and the juvenile Eastern.

Even from the lousy phone-scoped photos, you can see how distinctive these two subspecies (for now!) are. The smaller, “dumpier,” browner Eastern nicely contrasts with the larger, lankier, and much grayer Western. Also, note how the darker brown scapulars of the Eastern contrast with the rest of the wing; Western is more uniform. The head of the Eastern is also more contrast-y, and in this individual, the bill is so distinctly shorter and blunter.

Elsewhere, I finally got a chance to look for – and find – the juvenile Hudsonian Godwit that has been frequenting the river behind the Scarborough Marsh Nature Center for about a week now. This is the first “Hud-wit” that I have seen in two years here in Maine – this once-common migrant has definitely declined dramatically in the state.

Now, my eyes are on the weather maps, and after dusk, the radar, to see if I will be at SandyPoint at sunrise on Friday. This is the wind map as of 5pm. The northwesterlies behind the front are barely peeking into the region north of the St. Lawrence River in Quebec.

Currently, forecasters are suggesting that the cold front won’t pass through until tomorrow morning. However, with very light winds overnight, perhaps with a westerly component, there could be some birds on the move…depending on when this latest batch of rain and thunderstorms (the storms last night and this afternoon were wicked, weren’t they? And very un-September-like) moves through. Will the front get here soon enough? Will birds be moving directly behind the front? Will they be pushed offshore enough to need to reorient in the morning? I’ll let you know tomorrow!
