A Great May Week of Birding in Review, and Some Predictions for More Feathery Fun.

Simply put, it has been a helluva week of birding in Maine! Strong flights of migrants occurred on 5 of the last 7 nights, producing a whole lot of new arrivals throughout the region. And then there were rarities, but we’ll get to that shortly.

As for regularly-occurring migrants, birds are arriving right about on time now. By week’s end, some of the latest arriving warblers, like Blackpoll have begun to trickle in, while the early migrants like Yellow-rumped and Palm have thinned out considerably. Some locally-breeding Pine Warblers are rarely singing now, as breeding season for them is well underway.

Almost anywhere you went this week, 12 or more species of warblers was possible. I enjoyed 15 species at Florida Lake on Monday and 17 species at Evergreen Cemetery on Thursday, for example. The third week of May is when the coveted 20-species morning total is most likely around here, so you know I will be gunning for that in the coming days.

I added Lincoln’s Sparrow, Lesser Yellowlegs, White-crowned Sparrow (#126, 127, and 128 respectively) to my Bradbury Mountain patch lists this week, and a Lincoln’s Sparrow was the first in our Pownal yard (#116) on Sunday. Meanwhile, a spiffy male Orchard Oriole was the 114^th species at our store, a one-day wonder at our feeders on the 10^th. So it’s been a great week for patch listing as well!

And Scarborough Marsh was just awesome on Tuesday morning, when Katrina and I had unbelievable numbers (for spring) off of Eastern Road, including 1500+ Tree Swallows, 500+ Least Sandpipers, 400+ Barn Swallows, ~125 Greater and ~100 Lesser Yellowlegs, 75-100 Bank Swallows, 6++ Semipalmated and 2++ White-rumped Sandpipers (both FOY), 2 adult Dunlin, and the continuing Tricolored Heron. Nothing rare per se, but the biomass of birdage was impressive, and was definitely the highlight of the week.

Following the “Mega” rarity Northern Wheatear that was last seen last Saturday in Scarborough Marsh, rarity news has been decidedly southern in nature. Although small numbers of “overshooting” southern vagrants are typical in Maine every spring, the number of White-eyed Vireos (I caught up with one at Capisic Pond Park on Thursday with my friend Lois), Summer Tanagers (I saw one in Georgetown last week with Katrina; see above), and Blue-gray Gnatcatchers (they’re everywhere!) is most impressive. Then there was a Painted Bunting on Monhegan this week, a Swallow-tailed Kite at the Bradbury Mountain Hawkwatch on 5/7, and a Mississippi Kite also at The Brad as the grand finale on the 15^th. The widespread smattering of Orchard Orioles is a little more typical.

This pattern of southerly vagrants is not caused by birds being “blown” here in a simple sense, but instead we believe it is caused by southerly winds facilitating their arrival beyond their normal range – perhaps by causing a bird to travel much further (in relation to the ground) in each night’s flight thanks to a favorable tailwind. Perhaps others were entrained by strong winds off the South Atlantic Bight and were pushed northwards until they made landfall in the Northeast (I wonder if the Boston Fork-tailed Flycatcher arrived this way?).

Less fitting of any particular pattern is the remarkable adult Black-headed Grosbeak that was on Monhegan this week – at the SAME FEEDER as the Painted Bunting, 2 Summer Tanagers, a Lark Sparrow, and a Dickcissel. <expletive deleted> And, not to be overshadowed, a dapper male Ruff was found in Bangor.

With a deep southerly flow continuing, and some very unsettled weather coming for the weekend, I think things will be getting quite interesting in the coming days. (I don’t want to know how many “Island Birds” Kristen Lindquist will pick up over me on Monhegan this weekend!). Check out this wind map from the 15^th, showing a very strong southerly flow originating all of the way from Florida and the Caribbean.

For those of us not on Monhegan this weekend, I sure hope you’ll be birding hard – not despite the weather, but because of the inclement weather. At the very least, keep an eye on those feeders. Both here at the store and at home, we’re stocked up with mealworms, jelly, oranges, insect suet, and nut blocks. Not only will the cool, wet weather limit natural food sources, but the slow progression of the season continues to put a lot of important food sources well behind the birds’ required schedules.

For example, apples and cherries are only now starting to bloom. Early-arriving nectavores and insectivores flock to these (and other early-season bloomers like Shadbush, azalea, and quince) for both nectar and the insects attracted to that nectar. The lack of a lot of flowers so far this season has pushed many orioles (including some Orchards in addition to the regular Baltimores), Gray Catbirds, and Scarlet (and some Summers) Tanagers to feeding stations in above-average numbers. I expect that trend to continue through the middle of next week, as a stubborn upper-level low remains locked overhead producing unsettled weather.

So keep an eye out the window, get outside, and find some good birds! And regardless of rarities, it’s just a great time to be birding!

Three Days of Migration Watching in May -Day and Night.

3 Replies

In my blog last Wednesday, I made some prognostications about what we might expect for birds in the coming days. Let’s see how I did so far.

Rain began to fall Wednesday evening, and continued, heavy at times, through Thursday morning. With a persistent easterly wind, overnight migration was non-existent. In the rain on Thursday morning, Katrina and I checked out Florida Lake Park, but found only about 20 Yellow-rumped and 10 Palm warblers – fewer than in recent days. The local River Otter pair, however, put on a great show. Nothing new under the feeders at home (or at the store), either.

Afterwards, I took a spin through the local farms and fields, but found nothing out of the ordinary; it’s too early for most shorebirds anyway. Admittedly, however, I had vagrants on my mind (and still do! As usual). Although the southerly winds conducive to southern overshoots (as I discussed in the aforementioned blog) had yet to kick in, the deep easterly flow that we have been ensconced within could offer up its own surprises. With reports of the “largest incursion of Icelandic/European birds to Newfoundland in recent memory,” including amazing tallies of European Golden-Plovers, 9 Black-tailed Godwits, North America’s 4^th (or so) Common Redhank…yeah, the “Rarity Fever” in me can’t help but kick up. Perhaps something will ride one of those Iceland-Portland cargo ships that are in service these days!

Light rain continued through Thursday morning, diminishing to drizzle and fog until the afternoon, when a shift to westerly winds began to clear things out. Overnight, light and variable winds suggested a good migration should occur, but the radar wasn’t showing more than a light flight.

However, it was foggy for much of the night, and fog can obscure the image of birds on the radar, especially if they are flying low. “Birding by radar” is not infallible, and I had a feeling it might have been a little misleading this morning. A steady trickle of Yellow-rumped Warblers moving over the yard at dawn confirmed this. The weather was just too-not-terrible for there not to be a lot of birds on the go.

So off to Florida Lake I went. And, for a change this spring, I was not disappointed. 100+ Yellow-rumped Warblers, 20+ Palm Warblers, my first Northern Waterthrush and Black-throated Green Warbler (finally!) of the year, a singing migrant Greater Yellowlegs, and much, much more. I caught the lingering pair of Green-winged Teal copulating; are they going to breed here? Ring-necked Ducks had increased to 16 and there is still a pair of Common Mergansers here.

As the fog burned off, the sun shone brightly, and heat began to rise in swirling thermals, hawks took to the skies on the light westerly wind. I had to pull myself away from the hawkwatch kicking and screaming at 12:30, but by then we had eclipsed (at 10:35) our all-time record count of 4,474 birds when a Merlin streaked by. 388 Broad-winged Hawks and 22 Sharp-shinned Hawks were included in the total of 429 migrant raptors when I departed.

Last night’s passerine migration – yup, the fog on the radar definitely obscured the intensity of the flight! – was still evident well past noon, as Yellow-rumped Warblers were still on the go, reorienting inland after last night’s flight. Well over 200 had passed the summit by the time I departed, as did my first two Chimney Swifts and Eastern Kingbirds (also 2) of the year. And by day’s end, 705 raptors led by 583 Broad-wings were tallied, adding to our record totals. Around 4:00pm, our 5000^th raptor had passed – a milestone we never thought we would reach.

Come nightfall, the radar was active once again. Here are the 1am reflectivity and velocity images for example:

Notice the dark greens in the center of the return, but overall the rather narrow diameter of the image? My guess is that mostly overcast skies and a light westerly winds, perhaps including some turbulence from the passing cold front, kept birds low once again. But, without fog around, it was certain that this was birds – confirmed by the distance SW-NE pattern of the velocity image, and its speed. I think it was actually a lot of birds.

And come morning, Yellow-rumped Warblers were overhead as I stood on the back porch at dawn, and the Saturday Morning Birdwalk group and I headed over to Florida Lake. Yeah, it was good. Very good.

In the past few days, we’ve also finally had the first couple of reports of Ruby-throated Hummingbirds and Baltimore Orioles, so that those have just begun to arrive. As I mentioned the other day, food is in short supply for these backyard favorites, so feeders are going to be important for the first arrivals.

But no vagrants from the south, or East …yet!

Biddeford Pool Snowy Owl and Weather Discussion

1 Reply

This was the birding highlight of Tuesday morning’s visit with Katrina to Biddeford Pool.

The first photo was taken shortly after our arrival to The Pool, while the second two -with much more pleasant skies – was taken as we departed around noon. Although its plumage is much more faded and worn now, it is likely that this is the same Snowy that has spent the winter near the western end of mile stretch. Today, it was hunting voles once again on the incoming tide from one of its favorite rooftop perches.

While this was my latest Snowy in Maine, it is far from unprecedented following a massive irruption year. But seeing a Snowy Owl a mere two days away from May is still special; it could be a lifetime before we see an irruption of this magnitude again.

A little further down the road, where the second of the Mile Stretch Snowies overwintered, we found a pile of pellets below one of that bird’s favorite perches. Most were full of small mammal fur and bones, and the skulls were all of voles. One pellet, however, was pure thick, downy feathers – probably from a duck.

But with migration still at a virtual standstill, the rest of the day’s highlights were rather few and far between; very few migrants were around. A pair of Blue-gray Gnatcatchers around the beach parking lot was a nice, and I had my first House Wren of the year in the neighborhood, and my first Laughing Gull off of East Point. 1-3 Black-crowned Night-Herons were also my personal “FOY’s,” but they have probably been present here for at least a couple of weeks now.

The seas and skies sure looked like winter today, and the raw winds and low temperatures – and Snowy Owl! – sure made it seem more like early March than late April!

But yeah, migration has been kinda slow. Although, interestingly enough, the House Wren and Laughing Gull were right on time for me, most of the usual late April arrivals (Black-throated Green Warbler, Northern Waterthrush, Black-and-white Warbler, etc) are nowhere to be seen, and really, have I only heard one Blue-headed Vireo so far this season?

We all know spring has been running late this year, and I would say bird migration is now about 7-10 days behind schedule (catching up from the 2-3 weeks behind schedule of early April). Recently, our onshore winds (not conducive to facilitating migration for birds heading north) in this stubborn blocking pattern (a pattern that has seemingly become more and more regular recently) have not helped matters. Here, for example, is the wind map from Sunday, showing the low pressure system just south of Nova Scotia that was pumping in those onshore winds since late last week.

But take a look at today’s wind forecast…

Here we see the massive low pressure system marching across the Great Plains. But now, on the leading edge of it, we see a deep southerly flow, originating all of the way from the Gulf Coast. This southerly flow is expected to last for at least the next 48 hours.

Although the weather will remain unsettled – and we’re about to get a pretty good soaking tonight and tomorrow – through at least the weekend, I would expect quite a few migrants to begin to trickle in over the next few days. Simply put, some birds are running low on time to wait! And, as evidenced by the 73 and 110 raptors tallied passing The Brad over the last two days, respectively, despite easterly winds, it is clear that some birds simply have to make some progress, and will do so when conditions are at least somewhat favorable (or, at least not completely unfavorable).

Furthermore, these deep southerly flows at this time of year can facilitate the arrival of annual spring “overshoots” from the south (see Chapter 4 of my book, How to Be a Better Birder for a full explanation of this phenomenon). When I see weather patterns such as this, I begin to think about things such as Summer Tanagers, Blue Grosbeaks, and Hooded Warblers!

At least potential food sources (insects emerging from ponds; insects attracted to blooming trees) are getting a little chance to catch up before the bulk of migrant birds arrive. This phenology, or timing, of the plant and insect cycle is critical for migrant birds that need to refuel and/or then fuel up for the next leg of their journey. “Weird” weather such as this doesn’t bother birds as much as it bothers us, but it becomes a real problem when the weather results in the lack of specific food sources.

I haven’t seen much in the way of nectar-producing flowers yet – but Ruby-throated Hummingbirds and Baltimore Orioles often begin to arrive in the first week of May. This is going to be one of those seasons where well-stocked feeding stations are critically important to migrants, especially those that need insects and nectar. Our hummingbird and oriole feeders are out and ready for business, and our feeder is stocked with insect-laden suet blocks (check out our “Photos from Friends of the Store” gallery on our Facebook Page to see what one particular feeding station in Brunswick has been seeing eating insect suet) and live mealworms. It lies in wait for the first hummers, orioles, or any other migrants in need of assistance…oh yeah, any vagrants from the south, too!

White-faced Ibis Have Returned to Scarborough Marsh

4 Replies

For the 7^th consecutive spring, White-faced Ibis have been found in Scarborough Marsh. I found the state’s 5^th record in 2008 – a single adult bird – and in each of the next three years, a single adult bird was seen. It is more than likely that this was the same adult returning for each of those years, and likely beyond.

Things became a little more muddied in 2012, however, when three different White-faced Ibis (WFIB) were documented (that spring, I wrote an extensive blog summarizing the difference and the previous records. Although that was posted to my old Mainetoday.com blog that has since imploded, if anyone would like a copy of that synthesis, please let me know).

Photos from 2012 can be seen here.

Additionally, some earlier photos of the sub-adult bird can be seen here, although they are not of high quality.

In 2013, at least three individuals were identified once again.

So the question becomes are these birds all related? How many of these individuals have shown up for home many consecutive years? And, are they breeding?

Last year, WFIB were spotted on occasion through the end of the summer, confirming that the birds are not just spring overshoots or drift vagrants. Although the detection of – and ability to study the – ibis becomes much more challenging as the season progresses due to the growing marsh grasses, last year WFIB was a semi-regular sighting in the marsh. Some of my photos from July and August of last year can be seen here.

Juvenile WFIB are impossible to separate in the field from juvenile Glossy Ibis in the late summer and fall (by late winter, the development of the red eye and perhaps even facial skin coloration would at least tip us off to the possible identification). Therefore, if breeding is to be confirmed, it would likely have to be on Stratton Island – where they would likely breed within the large colony of Glossy Ibis (GLIB) – or, by conjecture as a population increases. Figuring out exactly how many birds are seen each year, and their ages, could help us track potential breeding (and perhaps eventual colonization?). It’s also fun – if you like this sort of thing.

Each year, WFIB show up in late April, about the time that the majority of the GLIB arrive, and this year, the birds were first reported on Saturday (4/19). Two to three birds were reported, and over the past week, we have tried to determine exactly how many birds they are, and, if possible, what ages they are.

On Sunday, Jeannette and I were planning on heading to the marsh in the afternoon anyway (to take advantage of the high tide on our rare extra day off), so looking for the WFIB first reported on Saturday added extra incentive. And luck was with us. As soon as we arrived at the marsh, we found a group of about 70 GLIB foraging close to Pine Point Road. We jumped out, and immediately found two White-faced Ibis within the group, along with one other bird of interest (a bird that looked absolutely fine for a pure GLIB, but with distinctly reddish-pink knees, and perhaps a pinkish hue on the rest of the leg. Jeannette, unfortunately, was unable to get photos of this individual).

Most obvious, there was this “bright-faced” bird.

Although the facial skin, especially right at the base of the bill, has a slight grayish tint, I see no reason to argue that this is anything other than an adult bird (or very near-adult, perhaps).

Secondly, there was this “pale-faced” bird.

Note the greatly reduced amount of white around the face, with no white behind the eye. In the field, I called this bird a sub-adult, but on close inspection of the photos, I don’t feel comfortable calling its age – other than it is definitely more than a year old. Although there isn’t much white on the “face,” the pure red eye, pink facial skin, and pinkish legs with brighter red-pink knees are all fine for an adult, in fact, as are the spiffy, glossy tertials. Perhaps a spread-tail shot could help confirm this. It might simply be a dull (facial-marking-wise) adult.

Meanwhile, photos from other folks suggest that a third WFIB, or perhaps a hybrid, is present. If it is, perhaps we will be able to compare these birds to those of last year, and perhaps even conclude that the same three birds are back. Regardless, it will be an interesting exercise, and quite the challenge, as ibis are a real challenge to age. In fact, we might not even know for sure how to age them! Of course, you know me, that doesn’t necessarily stop me from trying.

What intrigues me is that we have not yet documented a hybrid, even after an adult was present for 4-5 years. Since out of range WFIB are well known to hybridize with GLIB (and visa-versa), we often expected to see hybrid kiddies running around (at least by next spring when they would have been noticeable). Perhaps it did not breed, or the young did not survive. And/or perhaps it waited long enough for another WFIB to arrive. Whatever is going on, it will be most interesting to watch, this summer and beyond.

Common Teal to Northern Lapwing; American Woodcocks to Wood Ducks: 5 Great Days of Spring Birding!

1 Reply

Well, that was a helluva good five days of birding! And, I covered a heckuva lot of ground in the process. Yes, spring – and spring birding – is finally upon us.

After checking local hotspots on Thursday morning (lots of Killdeer and my first Eastern Phoebes), I began my trek eastwards after lunch. I was giving a presentation and book signing at the Maine Coastal Islands NWR headquarters in Rockland, thanks to an invite from the Friends of Maine Seabird Islands. On the way, I hit a handful of water overlooks, with the only birds of note being my FOY Fish Crows in downtown Brunswick and FOY Double-crested Cormorant in Damariscotta Harbor.

But then I arrived at Weskeag Marsh, and that was most productive. Highlighted by two drake “Eurasian” Green-winged (aka “Common”) Teal, a nice diversity of waterfowl also included two pairs of American Wigeon and a pair of Northern Pintail. I flushed two American Woodcocks and four Fox Sparrows from the short trail that leads to the viewing blind. Afterwards, I found a single 2^nd-Cycle Glaucous Gull with four 1^st-cycle Iceland Gulls still at Owl’s Head Harbor.

Here’s a poorly phone-scoped image of one of the Common Teal, showing the bold horiztonal white bar across the wing and the lack of a vertical white bar on the side of the chest.

Spending the night with friends, I then met up with staff from the Coastal Mountains Land Trust for a walk around their Beech Hill Preserve to discuss and offer suggestions as to augment and improve bird habitat there. A spiffy male Northern Harrier and a Northern Shrike (my 11^th of the season!) were me rewards.

I then took the (very) long way home, checking farm fields on my way to the Hatch Hill Landfill in Augusta. Although 900-1000 gulls were present at the dump – a nice number for here – all but 5 were Herring Gulls (plus three Great Black-backed and 2 Ring-billed). At least 10 Bald Eagles were still present however.

Working my way down the Kennebec, I checked the mouth of the Abagadasset River in Bowdoinham, which I found to still be frozen. Nearby Brown’s Point, however, had open water, and duck numbers were clearly building, including 44 Ring-necked Ducls and 50+ Green-winged Teal. Back at the store soon thereafter, I found our Song Sparrow numbers had grown from four to 12 overnight.

As the rain and drizzle ended on Saturday morning, the birdwalk group convened, and we headed inland (for the first time since December!) to work the “Greater Yarmouth Goose Fields.” Highlighted by two Cackling Geese that were first located on Thursday (a couple of hours after I checked the fields in the fog, dammit!) and yet another Northern Shrike (our third week in a row with a shrike on the birdwalk!), this very productive outing is fully covered on our website, here – as are all of our birdwalk outings.
One of the two Cackling Geese, phone-scoped through the fog.

Normally, the birdwalk’s return to the store is the end of my birding on Saturday, but not this week. Soon, Kristen Lindquist, Barb Brenneman, and I raced off to Jordan Farm in Cape Elizabeth to twitch a real “mega,” the stunning Northern Lapwing! Discovered Friday evening, the bird was enjoyed by many throughout the day on Saturday, but it was not seen again on Sunday despite much searching. This is the 4^th record of lapwing in Maine, and the third in just three years! I consider myself exceedingly fortunate to have seen the last two. My distantly-phone-scoped photos of the Cape Elizabeth bird hardly do this stunner justice.

Yet even still my birding day was far from over, as Saturday night was our annual “Woodcocks Gone Wild at Pineland Farms” dusk trip. Keeping an eye on the weather (the rain had cleared, but increasing winds were a concern), Jeannette and I wondered if we should postpone the outing. Moments after we decided to give the go-ahead in the afternoon, the winds began to gust – a lot. Then, at about 5pm, they died. When our walk got underway at 6:30, there was a little breeze once again, but it was not enough to keep the woodcocks from going wild! In fact, it’s possible that a little wind kept the birds’ display a little lower – especially the first handful of flights – which resulted in quite possibly the best show we’ve ever had here! At least 7 males were displaying, including one repeatedly right over our heads – and at least two more silent birds were observed flying by. Add to this lots of American Robins and a Northern Shrike before the sun set, and the group was treated to a wonderful spring evening performance!

Next up was Androscoggin County on Sunday with my friend Phil McCormack. While our primary target was a pancake breakfast at Jillison’s Farm in Sabattus, we were also hoping for a Redhead that was discovered on the outlet stream at Sabattus Pond a few days ago. Well, the pancake chase (the more important one!) was successful, but the Redhead chase was not. However, a very good day of birding was enjoyed nonetheless.

Scattered ducks on the river including Ring-necked Ducks and Common Mergansers, a couple of pockets of Tree Swallows, and other assorted species were trumped by two flooded fields along Rte 136 in Durham. With ponds and marshes still frozen, ducks are stacking up at more ephemeral – but unfrozen – habitats. Thousands of ducks and geese were present, mostly Canada Geese, Mallards, and American Black Ducks. However, between the two fields, we tallied an unbelievable 273 Wood Ducks (probably about quadruple my previous high count in the state). Two immature Snow Geese were my first of the year, and very rare away from the coastal marshes in the spring. 18 Green-winged Teal, 12 Ring-necked Ducks, 10 Northern Pintail, and two pairs of American Wigeon were also among the masses.

Although these phone-scoped photos hardly do the scene justice, they should at least give you a taste of what things looked like.

After brunch, we birded the west side of the Androscoggin River (more Ring-necked Ducks and Common Mergansers, etc) before spending our last hour of our birding (half) day at Bradbury Mountain. Our disappointment over missing an unprecedented 9 Sandhill Cranes was alleviated when #10 was spotted, along with my first two Ospreys of the year.

After four days of extensive birding, my Monday agenda at the store was lengthy, but the weather in the morning was just too good to pass up! A spin of the local waterfowl hotspots was fruitful. The Goose Fields yielded the two continuing Cackling Geese along Greely Road, along with my first American Kestrels of the year, and my FOY Wilson’s Snipe, also along Greely.

No luck finding a lingering Barrow’s Goldeneye in the Harraseeket River, but at Wharton Point, a group of 7 Northern Shovelers was one of the largest flocks of this species I have seen in Maine. My first Greater Yellowlegs of the year was also present, as were 60+ Green-winged Teal, 16 Ring-necked Ducks, about 30 distant scaup, 8 American Wigeons, and 1 Northern Pintail among several hundred American Black Ducks.

Two joyous hours at the Brad were full of raptors: 127 birds had past the watch when I departed at noon, including 4 Osprey. Red-tailed and Red-shouldered Hawks continue to add to their all-time record tallies. Hundreds of Canada Geese were sorted through, hoping for a rarity, while other migrants included Tree Swallows, American Black Ducks, Common Mergansers, and Great Blue Herons.

Furthermore, signs of a good flight last night included the return of Golden-crowned Kinglets to the area – after we were virtually devoid of them this winter, and an increase in Red-breasted Nuthatches (relatively few and far between this winter as well), Song-Sparrows, and at the store, a Fox Sparrow – a bird we don’t get here every spring due to our open habitat.

So long story short, it’s been a great few days of birding! But now, I should probably get some work done!

Yup, More About the “Westbrook Gull.”

1 Reply

A great day of birding on Friday included new arrivals and migrant waterfowl around Scarborough Marsh (oh yeah, and two more Snowy Owls), continuing good numbers of white-winged gulls in Portland Harbor, and “quality time” with “Westie,” the still unidentified white-winged gull in Westbrook (highlights posted to the store’s Facebook page as usual).

As for this frustrating, fun, and challenging obsession of mine with the “Westbrook Gull,” I won’t rehash the entire story here, but for that please visit this blog entry from January.

During our outing on Friday, Kristen Lindquist and I enjoyed my best photo session of the season with the bird. I’ve posted a variety of photos of the bird into the growing gallery of photos of this bird on our store’s Facebook page, here.

But here I want to discuss a few of the more pertinent images, and explore some of the still-unanswered questions about this bird. First and foremost, and perhaps the single most critical factor in being able to simply dismiss this as an Iceland Gull – likely (due to its pure white wingtips and pale mantle) of the nominate subspecies glaucoides – is the fact (not subject to interpretation) that the wings are short: only two primaries extend beyond the tail, as with Glaucous Gull, and unlike the long, four-primary extension of Iceland Gull of either subspecies. No photo of this bird in four years has shown the typical “long-winged” appearance of Iceland Gull of either subspecies.

It’s impossible to ignore this significant structural feature, but of course, we never base an identification (or lack thereof!) on any one particular characteristic. Unfortunately, nothing else is this clear and distinct.

As the bird reached adulthood, I had hoped that the orbital ring – the narrow band of bare skin that surrounds the eye – might yield a clue, and now that we are in late spring, the bird’s head is pure white and the brighter bill suggests that it is now in “high breeding” (or at least close to it), the color should be as true as possible. Howell and Dunn list the orbital ring of Larus glaucoides glaucoides as pinkish to red, turning brighter reddish by spring. L.g kumlieni is described as purplish-pink to reddish, brightening by spring. As for Glaucous Gull: orange to pale pink flesh, brightening in spring to “orange or chrome yellow.” As for Westie?

I call that simply “pink.” But does that only mean that this bird is not in high breeding yet (which is suggested by the still-brightening yellow of the bill)? If this is as colorful as it gets, it’s a significant strike against a Glaucous Gull, or at least a pure one, but it is not clinching for Iceland Gull of either subspecies, either.

Westie’s dominance of the park leads to aggressive behavior towards other gulls, especially anything of similar size or larger. While the aggressive behavior is more typical of Glaucous Gulls, I think the rather unnatural environment, along with the decided “home-turf’ behavior negates the value of this circumstantial evidence. What it does mean, however, is that it is a royal pain in the ass to get this bird next to something else other than a smaller Ring-bill. I would like to see it next to an adult Herring Gull to compare grayscale, but especially an Iceland Gull of any shape, size, or variety! This was the closest I have come to that goal.

As for Herring Gulls, this youngster was tolerated for a few seconds.

In other words, I still don’t know what this is. But at least it gives me something to do in the winter, and offers a really good exercise in studying the finer points of the endless variation in “large white-headed gulls.” Oh yeah, and it’s a pretty bird, too. Might just have to leave it at that…for now.

And believe it or not, there are other birds at Riverbank Park and the adjacent Westbrook Riverwalk. On Friday, this included one of the continuing Canvasbacks (a rarity in Maine), and a handful of ultra-cooperative Cedar Waxwings!

The Decline of Barrow’s Goldeneyes in Freeport and Beyond.

3 Replies

I like Barrow’s Goldeneyes! And I like getting to see them every winter, and sometimes in numbers…and only a few miles away from home. But I wish I could see more of them.

Unfortunately, with each passing year, I am seeing fewer and fewer. My local Barrow’s Goldeneye (BAGO) “patch” is the Lower Harraseeket River here in South Freeport. A couple of miles of river between Winslow Park and Bartol Island hosts the southernmost wintering flock on the East Coast…or at least what nowadays passes for a flock.

One of just a handful of locales in the state that regularly hosts more than one or two birds, this once-impressive flock has declined dramatically in the past ten years that I have been watching them. Scanning the river once a week, from early December through the middle of April from a variety of locations (Sand Beach, the Town Wharf, the Harraseeket Yacht Club, Winslow Park, and/or Wolfe’s Neck Woods State Park) I have kept track of arrival and departure dates, and perhaps most importantly, overall numbers.

“High counts” are the maximum number of birds seen at one time in a given time period. While some individuals come and go over the course of the winter, it seems to me that the seasonal high count is a reasonable way of estimating the local population (as keeping track of individual birds is impossible). And my high counts for each of the last nine winters show an alarming pattern:

2004-2005: 23
2005-2006: 15
2006-2007: 10
2007-2008: 2
2008-2009: 9
2009-2010: 2

It has become readily obvious that the less ice there is, the fewer Barrow’s concentrate in the Lower Harraseeket. A deep channel and strong tide combine to keep at least a stretch of the gut at the mouth of the river (between Winslow and tiny Pound of Tea Island) open in the coldest winters. Back in 2004-2005, the river was almost completely frozen, and the narrow strip of open water was so thick with ducks, especially Common Eiders, that it looked as if you could almost walk across the river on their backs!

We also know that the climate, and the temperature of Casco Bay, is getting warmer (yes, that is fact, and yes, this year’s cold winter/spring weather does nothing to disprove this – note that “climate” and “weather” are actually different words that describe different things!). Therefore, I optimistically wondered if the apparent decline in the population of BAGO was nothing more than a lack of ice-caused concentration. The less ice, the fewer BAGO I see.

Therefore, when about 90-95% of the Harraseeket froze this winter (the most extensive coverage since 2004-2005) and ducks concentrated in numbers not seen since then, I was cautiously optimistic that BAGO number would spike:

2013-2014: 5

Not the spike I was hoping for. I searched long and hard to find BAGO elsewhere in the vicinity, but I did not see any (the closest was an overwintering bird in South Portland that has returned to the Fore River for the last two or three years now). That’s a 78% decline from the 2004-2005 high.

Unfortunately, Christmas Bird Counts occur too early in the winter to adequately gauge seasonal high counts of BAGO, although the graph does reflect a decrease in the past ten years (the long-term data set is clouded by low birds-per-party-hour totals as a whole, along with misconceptions about identification in the past).

But this decline is not just apparent in the Harraseeket. Birders have detected a decline in all other known wintering concentrations, especially in Belfast Bay. They are now longer seen on most visits in mid-winter there and it’s been a long time since I have seen a report from Bucksport. However, according to the 1996 A Birder’s Guide to Maine, *1 aggregations of 15+ birds are “regular features in most winters” at these two sites.

In other words, at least in Maine, the decline is real. And it’s time for the Department of Inland Fish and Wildlife to do something about it. No more half-assed, non-action policies that bow to the hunting lobby. No more “please tell us if you shoot one and then say you’re sorry and it will be OK” (with only a disincentive to do so) state policy. *2

In 2009 IF&W listed the Barrow’s Goldeneye as “Threatened.” …And has done almost nothing since, other than set up surveys that are conducted every four years. Oh, and they hung up some posters at boat launches asking people to not shoot them (might as well put a target on them, in my mind).

Let me be clear, there is no evidence to suggest that hunting is causing a decline in BAGO. I think much larger factors are at play. There’s acidification and warming of the ponds and lakes in their limited and narrow eastern Quebec breeding range to changes in winter food sources. Forestry practices could be reducing the availability of suitable nesting cavities as well. There’s lead ingestion and heavy metal bioaccumulation. Then there’s reduced ice in most winters in their primary wintering areas of the St. Lawrence estuary (thereby reducing how many birds come further south) to competition with other native and non-native species (BAGO eat small mollusks, especially mussels – could invasive Green Crabs be impacting the food supply for ducks here, too?). In other words, there are a lot of possible proximate and ultimate causes to the species’ decline. But if hunters shoot one or two (by accident, of course) of the remaining 5, well then the decline becomes even quicker. Even repeated disturbance from concentrated hunting pressure on other species could be impacting where the birds tarry, where they feed, and how much energy they waste fleeing boats and shots.

I am not opposed to waterfowl hunting. But I am opposed to hunting that impacts an endangered species (see, for example: Conservation and Management/Effects of Human Activity in the Birds of North America entry referenced below). The closure of a handful of tiny areas will affect very few hunters, and with more than 99% of the state still available to them, this rates as a minor inconvenience at most. However, this fraction of a percent of water closed to hunting could protect a significant majority of the wintering population – or at least what’s left of it. At the very least, this could buy us some time to find out what the root of the problem is.

I like Barrow’s Goldeneye, and if you do too, it’s time to pressure IF&W and politicians to act. Otherwise, there is a very legitimate chance that this bird will no longer be a part of Maine’s winter avifauna.

A Vermont and Montreal Roadtrip In Photos

6 Replies

Jeannette and I made a run for the border in our annual pre-hawkwatch roadtrip getaway. We’ll be covering Katrina’s days off at the Bradbury Mountain Hawkwatch through the end of the season. Then, my guiding season kicks off in full force through early July. In other words, it’s a good time for us to get a little break.

This year’s destination was a visit with family in Vermont, followed by a few days in Montreal. I had not been to Montreal before – no excuse for that, really – so this was a good incentive to head (mostly) west. Sure, the weather could have been a little more seasonable, but we enjoyed a really great trip nonetheless.

While this trip wasn’t necessarily a “birding trip,” we obviously were going to do some birding. And there were a few “goodies” around that, if nothing else helped guide us in fruitful directions. First up was the Northern Hawk Owl that has been spending the winter in Waterbury, Vermont. Since we had to pass through the intersection that the bird has been frequenting on the way to see the fam, I don’t think this counts as a chase, does it?

Although most hawk owls are notoriously tolerant of people, this bird was ridiculous! People were walking back and forth on a trail right below it, and it didn’t care.

Then, spotting something of interest, it dove through the line of admirers, and landed in the snow. It scuffled around for a bit, and then came up with a White-footed/Deer Mouse, which is proceeded to devour on a nearby snag…in clear view of everyone. Returning to its original perch, it flew between two photographers, right at head-level!

The lighting and the proximity were so good that I believe these are the best phone-scoped photos that I have ever taken!

After visiting friends and family, we departed the next day. Of course, we couldn’t help but stop at the hawk-owl once again. “Let’s just drive past this Northern Hawk Owl,” said no one, ever.

After lunch in Burlington…

…we dipped down to Charlotte to board the ferry over to Essex, NY. With such extensive ice on the lake, the only open water is limited to the ferry channels. Ducks have concentrated in this narrow band of open water, including some very good birds. The Tufted Duck being seen here was nothing more than an excuse to take the ferry, and we are very glad we did.
This was a great little “mini-pelagic!” In fact, after we took the car across to NY, we hopped back on as round-trip passengers to have another look. Good thing we did, because as we began the half-hour journey back to Vermont, the Tufted Duck was right in front of the bow! And Jeannette “nailed” it, I think it’s safe to say.

In addition to the Tufted, impressive numbers of Common Goldeneyes and both Greater and Lesser scaup were enjoyed and extensively photographed. Mallards, American Black Ducks, a small number of Common Mergansers and Buffleheads, 3 Ring-necked Ducks, 2 female Long-tailed Ducks, and 1 White-winged Scoter (the latter three only in New York, and the final two being good birds for the season here) were also present, and early in the third leg, we spotted a female Barrow’s Goldeneye among the masses for a nice addition to my paltry Vermont state list. Jeannette very nicely augmented here library of waterfowl –especially flight – photos, and this fun little ride turned out to be a real highlight of the entire trip.

How many species can you identify in this photo?

A quick stop to look for coffee in Plattsburgh, NY resulted in what was perhaps the best cupcake we have ever had (a butter cream-iced tres leches cupcake at Delish), and eventually we made our way across the border and arrived in Montreal in the evening.

The next morning, we walked from our downtown hotel to Parc du Mont Royal, the expansive park in the heart of the city. There’s been a Black-backed Woodpecker here all winter, but we did not know exactly where. We did find a grove of Scotch Pine that had the classic sign of foraging Black-backs, but we didn’t see it…or much else, really. Just like at home, deciduous-dominated forests are awfully quiet right now.

After lunch, we visited the Botanical Gardens, including their impressive Insectarium and extensive greenhouse biomes. Stealing the show, however, was the free-flying butterfly (and some moths) exhibit.

A stroll around Olympic Park…

…Was followed by dinner, at a place with 30 kinds of poutine on the menu: Poutine la Banquisse!

The next day, another walk at Parc du Mont Royal (which was actually less birdy than our first visit) …

…was followed by exploration of Old Montreal and the OldPort. Unfortunately, the weather had taken a turn for the worse.

The storm was fully upon us…

…as we ventured out for our “splurge” dinner of the trip at the famous Au Pied de Cochon. Because we didn’t have enough poutine the night before, we shared the intriguing and tasty fusion of a poutine temaki, and the duck carpaccio. Entrees were outstanding as well, with Jeannette getting primal with a Bison rib as I went all in with what may have been the best sandwich I have ever eaten – and by far the most expensive! With 10 grams of truffles and an apparent three pounds of butter, this was not your everyday grilled cheese!

The snow was piling up as we departed the restaurant…

…and about 8 inches had accumulated by morning. Now that we actually knew where to look for the Black-backed Woodpecker at Mont Royal, it turned out it was rather east to find after all!

Before hitting the road, we took a walk around Ile Sainte-Helene, which was actually quite birdy; the birdiest place in the city during this short visit. In addition to the usual woodland residents, goodly numbers of Cedar Waxwings and American Robins were present. Waterbirds in the fast-moving river were limited to four Common Mergansers and a single Common Loon, however.

It was a long and slow drive home, in large part due to the heavy snow in the mountains. With about two feet in some places, a few of the passes in northern New Hampshire and Maine were a little interesting. I think it’s safe to say it was a good idea to have taken our Subaru on this road trip!

Back to work early in the morning on Friday, we were very pleased to be greeted at the store by some Red-winged Blackbirds. The hawkwatch is underway, with a goodly 38 birds on the first day (6 Red-shouldered Hawk!), spring is definitely here…even if, once again, it doesn’t feel like it!

A (Very) Early Spring Week in Review

Our Saturday Morning Birdwalk surveyed the waterfront in Freeport and Yarmouth. On Sunday, Kristen Lindquist and I enjoyed an epic white-winged gull show in Portland, before working our way around the Cape Elizabeth shoreline. Then, on Monday, we birded from Biddeford Pool through Scarborough Marsh with Snowy and Great Horned owls, Rough-legged Hawk, and Ruddy Turnstones among the many highlights.

Further south, Jeannette and I covered Kittery through Wells, as is our tradition on the first Tuesday in March. Another exceptionally productive day was enjoyed, including two more Snowy Owls and a Common Eider of the northern subspecies, borealis.

Wednesday was spent dealing with various car issues and seed delivery, so birding was limited to the woods near our house, and the feeders of course. Same for Friday, where at Hedgehog Mountain Park, a mere 7 species was actually the most that I have detected in a couple of months there. In between, I was back in Portland and Westbrook on Thursday, and although the Westbrook riverfront was a disappointing, the continuing white-winged gull show in Old Port more than made up for it.

While “new arrivals” were few and far between this week as bitter cold continues, there were definitely signs of the season. Waterfowl are obviously on the move: Brant, Canada Geese, Mallards, and American Black Ducks are returning in numbers, while the concentrations of seaducks, especially all three scoters, was greatly reduced as these birds have begun to disperse – if not actually migrating north.

For the first week of March, I recorded very few “first-of-years” this week: Great Horned Owl, Yellow-rumped Warbler, and Fox Sparrows. Of those, only the sparrow is likely a true migrant; the owl is a resident, and the warbler likely wintered locally. American Robins were definitely on the move, however, with several flocks noted moving northbound (at least at the given time), and American Tree Sparrows also seem to be on the go.

New reports of Snowy Owls – especially inland – likely included northbound migrants. While all three of the individuals that I saw this week seemed to be birds that were continuing in a specific area for several weeks or more now, the fact that Kristen and I only saw one bird in a very thorough search at Biddeford Pool (four had been present for a couple of months now) suggests birds are already departing. Northern Shrikes – such as the one that briefly visited the yard here at the store on Thursday (our second of the season) are also likely migrating right now.

In the woods there is a different story, however, as even the local residents are a little less active vocally right now than we would expect. I have yet to hear a Brown Creeper sing – although I am seeing them on regular basis – and Golden-crowned Kinglets remain very few and far between. And other than goldfinches and resident House Finches, finches remain virtually non-existent.

But all of this is about to change, and my guess is that it will change rather rapidly. In fact, with the winds turning south today, I wouldn’t be surprised if a few Turkey Vulture and Red-winged Blackbird reports trickle in this weekend. And once the snow really begins to melt (especially to our south), expect those floodgates to really open! (Any day now…any day now…)

Snowy Owl, The Cliff House, York, 3/4/14. As you have seen on this blog, our store’s Facebook and Flickr pages, etc, most of our Snowy Owl photos this winter have been of relaxed birds, often with their eyes closed. Few have been “perfect” shots, whether in lighting or resolution. And we’re proud of that! To us, the birds ALWAYS comes first, and we pride ourselves in minimizing any chance at disturbance. Unfortunately, this bird was sitting close to the parking lot and we spooked it before we knew it was present. A pair of crows likely also affected the bird’s immediate response. As it flew away from both us and the crows, Jeannette snapped some photos, as the bird first flew straight out to sea – thereby ditching the crows – before returning to land a short distance away. We backed off and left it alone. With a lot of unethical and selfish behavior occurring – as always – around charismatic owls around the country, we support the idea that the circumstances of photos be explained when it shows a behavior that may have been modified by our presence or behavior.

A White-winged Gull Convention in Portland Harbor

3 Replies

On Sunday, Kristen Lindquist and I worked Portland Harbor for gulls. In my usual routine, I started at the Maine State Pier and worked my way west, checking all of the piers and roosting locations in Old Port. I was pretty happy with the 4 first-winter Glaucous Gulls and a healthy handful of Iceland Gulls from the state pier, and we continued to see Iceland Gulls here and there as we continued along.

It was a good day for gulls in the harbor, but we didn’t realize just how good it was until we got to the end of the “Fish Pier.” There, everywhere we looked we saw white-winged gulls! Out by the dredging barges there were white-winged gulls. Feeding at the rips around the channel markers there were white-winged gulls. And all around the fish pier there were white-winged gulls!

I was very conservative in my counts, and yet tallied an exceptional 12 first-winter Glaucous Gulls – an all-time state high count for me. But it was the abundance of Iceland Gulls that stole the show; 4 adults (all with completely different wing-tip patterns of course), at least three 2^nd-winter, and an astounding (for southern Maine, anyway) THIRTY-TWO 1^st-winter birds. With that many, it was not surprising that the whole range of variation of “Kumlien’s” Iceland Gulls was to be seen, but try as I might, I couldn’t find a single bird that even allowed for an attempted stringing of a Thayer’s.

Despite starting the day by saying, “I am not taking any more first cycle Iceland Gull photos this winter,” with this many birds around, I couldn’t help myself. Here’s a selection of photos, starting with two phone-scoping using an iPhone 4S, Phone Skope adapter, and a Zeiss Diascope FL, followed by “better” photos using my Nikon D80 with a 300mm lens.

At the aforementioned outflow pipe.

Adult and 1st/2nd Cycle “Kumlien’s” Iceland Gulls.

1st cycle and adult “Kumlien’s” Iceland Gulls.

Wait, that’s not an Iceland Gull…sorry, I got distracted…

After second breakfast, we checked in at Mill Creek Cove, where the outgoing tide was attracting gulls to the mouth of the creek as usual. With birds heading to and from the Old Port, we didn’t add to our earlier counts, but there were at least 4 1^st-winter Iceland and 2 1^st-winter Glaucous Gulls present. Oh, and this rather confiding female Green-winged Teal was dabbling with the Mallards.

showing a little more green speculum than usual on one side.

Then we worked the Cape Elizabeth shoreline, highlighted by 3 Greater Scaup at Kettle Cove, 11 Brant at Dyer Point, and these 28 balls of awesomeness (aka Harlequin Ducks; phone-scoped photos).

]

But back to those gulls…why so many? While the number of Herring and Great Black-backed gulls (and the expected relatively small number of Ring-bills) were average (at least by recent winters’ standards), this is by far the most total white-winged gulls that I have seen in PortlandHarbor in the 13 years I’ve lived here. Some of these gulls are probably northbound migrants, but clearly there was something more at play here.

For one, there’s a dredging operation ongoing in the main channel of Portland Harbor. While we didn’t see any gulls obviously foraging on the dredge spoils being pumped into the barge, or immediately around the buckets scooping up the muck, there were birds standing around on the new moving “islands.” I wondered if a lot of these gulls were following/riding the barges in from where they are dumping the dredge spoils seven miles offshore. But in today’s Portland Press Herald, I read that the occasional dynamiting of underwater bedrock would kill some fish, and then the “seagulls’ (sic… ahem!) were feeding on the dead fish. That would certainly augment the already-occurring food sources in the harbor.

But most of the Iceland Gulls today were centered around the outflow pipes of various lobster-related facilities, as usual. Meanwhile, the high tide limited roosting and foraging opportunities along the coast, and here in the harbor.

So my guess is that the time of year (migrants), the dredging operation, and the tides all helped to greatly increase the volume of white-winged gulls present today to numbers not seen in recent years – at least not since Portland had a thriving year-round fishing industry. Obviously, this is just conjecture, but whatever made it happen, I was happy to be there to enjoy it!
