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

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

2 Replies

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:

-6:23-10:45am.
-37F, Clear, Light northwest, increasing.
-Jenny Howard and Jeannette Lovitch assisting with the count.

1 Northern Waterthrush
1 Red-winged Blackbird

1 Monarch butterfly

Total= 4,134 (*2^nd highest count of all time!)

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.
– 6:21-9:05
– 41F, Clear, Calm becoming very light west.

Total: 801

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!

Current Birds, Weather, Predictions . . . and Pretty Shorebird Photos

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!

A Record-setting First Day of the Season at Sandy Point

A MEW GULL in Thomaston!

4 Replies

On August 3^rd, Don Reimer found Maine’s Third State Record of a Mew Gull in a parking lot in Thomaston. While it was seen in the area for most of the day, it was not seen by anyone on the 4^th – myself included – despite extensive searching. However, a few days later, Don relocated it, and it has been seen regularly since, although it is not always in the same place at the same time, and it seems to feed somewhere unknown at low tide.

After returning from Hawai’i on Friday, I was happy to see the bird has kindly awaited my return. Today was the first chance I got to head over, and at 7:45 I met Kristen Lindquist in the parking lot behind downtown Thomaston. Kristen was studying about 30 Ring-billed Gulls in the parking lot until a birder drove by and flushed them. Apparently, a few gulls from rooftops and/or a nearby field joined the flushed birds, and as they settled back down or flew off, I noticed a single, seemingly darker gray bird sitting atop a basketball hoop in the adjacent playground.

And sure enough! I snapped a few phone-scoped images, including this one.

Boy, that was easy, for us anyway (the gull is hard to see atop the basketball hoop here)!

A short while later, it flew to a nearby field next to the Oceanside High School. There, a jogger was doing laps around the track. Although the bird was never too perturbed by this, it did fly a short distance when the jogger would be a little too close for comfort. This afforded me a perfect opportunity for exactly what I wanted: flight and spread-wing photos. Shortly thereafter, it flew off the field and onto the roof of the elementary school where we left it at about 9:00.

(Click on the photos for a larger image)

Side-by-side with a Ring-billed Gull:

So, what is this? Other than a big, fat, mess?

It’s definitely a bird in the Mew Gull (Larus canus) Complex, which here in the States, we refer to as composing four subspecies. There’s “Mew Gull,” L.c.brachyrhynchus that is common in the west, breeding from Alaska to extreme northwestern Manitoba and south through the coast of British Columbia, and wintering along the Pacific Coast from Washington into Baja California. However, vagrants that have been recorded on the Eastern Seaboard have mostly (I believe) been assigned to the expanding European population, L.c.canus, or “Common Gull.” There’s also the “Kamchatka Gull” (L.c. kamtschatsensis) of the Russian Far East that is a regular rarity in Western Alaska, with perhaps a few claimed elsewhere on the continent (I am vaguely recalling one in Massachusetts?). Finally, there is L.c.heinei of Siberia, which may just be an intergrade between Common and Kamchatka Gulls and I am unaware of any possible records of this in North America.

In short, the European “Common Gull” actually seems to be more likely on the East Coast than the North American “Mew Gull.” But most records are from winter, and most birds do not have a plumage as trashed as this individual.

The bird appears small to me, with a relatively thin bill (although it’s on the long side), and a relatively dark mantle, all of which would be points in favor of Mew Gull. However, the plumage is so ravaged, that it’s hard to even age the bird. Is it an advanced 2^nd cycle, a retarded 3^rd cycle, or an adult that had some really bad days? Intermediate-aged birds in the complex are notoriously, well, complex – and very difficult, at best, to identify.

But what can we actually see?
–          Fairly broad white windows in outer two primaries (primaries 10 + 9)
–          Little to know white between the black and gray on P8 (although this is probably only of value on an adult.
–          P7 is trashed
–          Is that a new P6 growing in? (One primary is definitely missing as well, could it be P1?)
–          The four new primaries have a fairly broad white tip.
–          The legs are dull olive-y (subadult-like).
–          The bill is fairly bright yellow at the tip with an olive-y base (adult-like).
–          The tail is too trashed too look for black spots at the tip (expected in a 2^nd cycle Mew Gull, but not in a Common)
–          The eye is fairly dark.

So, we have an odd time of year for a vagrant gull, and we have a trashed plumage. Can we narrow it down to a probable subspecies? I will be sending this blog out to those who know various members of the Mew Gull Complex better than I do, and I will let you know what I learn. Whatever it is, I got myself a state bird today!

Shorebird Pseudo-Big Day

2 Replies

Luke Seitz and I embarked on a semi-serious “Shorebird Big Day” on Wednesday. I say “semi-serious” because we didn’t exactly try too hard to build our list…at least not after our first stop. Instead, we spent more time watching shorebirds, studying, and photographing them. We still, however, tallied 14 species of shorebirds, but instead of heading inland to pick up Killdeer, Spotted Sandpiper, Solitary Sandpiper, and Upland Sandpiper, we just splashed in the water and studied dowitchers at Hill’s Beach. It wasn’t a bad way to spend a gorgeous summer day.

We began in the morning at high tide by scouring Scarborough Marsh from the Eastern Road Trail. If we were to have a chance at 20 species of shorebirds on the day, we would need to add a rarity or two from the pannes. Unfortunately, high water levels from all of the recent rain minimized habitat, and shorebirds were not as plentiful as we would have preferred. We did, however, see 2 or 3 Stilt Sandpipers, a decent bird in the summer. Other than Greater Yellowlegs, with about 55 individuals, numbers were relatively low: 75 Semipalmated Sandpipers, 40 Short-billed Dowitchers, 25+ Least Sandpipers, 8 Lesser Yellowlegs, 3 Black-bellied Plovers, 2 Semipalmated Plovers, and 1 Willet.

Making up for the low shorebird totals, however, were the high wading bird totals: 85 Snowy Egrets, 60 Great Egrets, 40 Glossy Ibis, 39 Little Blue Herons, and 9 Great Blue Herons. In addition to teasing out one of the continuing White-faced Ibises and spotting the continuing full Tricolored Heron, we also saw BOTH of the presumed Tricolored Heron x Snowy Egret hybrids. Yup, there are two of these beasties out there!

The first is the bird that has been present all summer, with a ghostly cast to an otherwise Tricolored-like pattern. Pure white is confined to the belly, the throat, and a thin line in the foreneck.

However, recently, a second bird has appeared, which is very reminiscent of the first, but has some splotchy areas of white, including mostly white wingtips. I believe I saw this bird on July 18^th when I was out with a client and sans camera; I remember commenting (and my field notes confirm) that I didn’t remember so much white in the wing

Meanwhile, it was nice to see that at least one of the White-faced Ibises continue, although at this stage of molt, it was impossible to age. It was also not very close. Here’s Luke’s best shot (mine were not passable at all).

After spending more time with waders and a little time of sparrows, such as this Nelson’s Sparrow…

…we attempted to regain our shorebird focus over at Pine Point, as the tide was rolling out. The mudflats had plenty of birds, including a few birds that would be important for a Shorebird Big Day, such as the pair – now, featuring two fledglings! – of American Oystercatchers (the only breeding pair in the state!). We also had four Whimbrel, along with 296 Semipalmated Sandpipers, 124 Semipalmated Plovers, 25 Willets, 25 Short-billed Dowitchers, 19 Black-bellied Plovers, 3 Ruddy Turnstones, and 2 each of Lesser and Greater Yellowlegs.

But with a morning total of a mere 11 species of shorebirds, we elected for a leisurely lunch at Saco Island Deli instead of heading inland to work on our shorebird list – it is really too early in the season for a true Shorebird Big Day, but I am not sure if I have ever hit 20 in July, and since this was a day we both had a chance to get out all day together, we figured it was at least worth considering. Anyway, on the incoming tide, we visited Hill’s Beach, where once again, we elected to forego shorebird listing for shorebird “quality” time, and therefore just spent close to three hours playing in the sand.

While the two Red Knots…

…4 Piping Plovers (a pair fledged two young here for the first time in recent memory), and 8 Sanderlings brought our count to 14 species on the day, we became distracted by photographing terns and studying dowitchers. While our goodly count of 155 Semipalmated Plovers were augmented by about 65 Semipalmated Sandpipers, 8 Black-bellied Plovers, 4 Ruddy Turnstones, and 1 Least Sandpiper, it was the 120 or so Short-billed Dowitchers that kept our attention.

We were looking for individuals of the interior subspecies hendersonii, as I did on Sunday with Phil. (See blog and photos here:

https://mebirdingfieldnotes.wordpress.com/2013/07/28/biddeford-in-shorebird-season/). We had what was possibly the same bright bird as Sunday (see above) fly-by, it was the paler birds that had us intrigued.

We thought the combination of a bright orange chest, and a fair amount of orange between the legs and on the undertail coverts, compared with the paler face and lightly, but distinctly spotted flanks and side (especially the side of the breast) of this bird made it look “good.”

But we were pondering how extensive of color a hendersonii “needs” to have, as most of the individuals of the expected Eastern subspecies griseus, also were showing at least a touch of peachy-orange color in the undertail, etc.

Here are some typical, and typically variable, griseus for comparison.

In the end, we simply said, “who knows!?” and went back to photographing other fun stuff, such as this Bonaparte’s Gull…

And this juvenile Roseate Tern…which was actually one of my targets to photograph today.

Ok, so we really quit on the Big Day attempt by about 10:33 in the morning, but 14 species of shorebirds included Stilt Sandpiper, American Oystercatcher, and two hendersonii Short-billed Dowitcher, along with two Tricolored Heron x Snowy Egret hybrids, White-faced Ibis, Tricolored Heron, a mid-summer marsh Merlin (these birds have simply got to be breeding in coastal Cumberland County!), it was hardly a bad day of birding. In fact, it was actually a spectacular day!

Biddeford in Shorebird Season

“Shorebird Season” is in full swing, and the greater Biddeford Pool area is one of the best places in the state to observe and study shorebirds. Although numbers usually pale in comparison to the Lubec Flats and Scarborough Marsh, and diversity usually lags well behind the latter as well, the area often provides some of the best opportunities to study shorebirds, between Ocean Avenue and Biddeford Pool beach on the high tide, and Hill’s Beach at low tide.

Today, Phil McCormack and I birded the area thoroughly, beginning with viewing of the extensive mudflats of The Pool itself. Birds were already well dispersed by the time we arrived this morning, so it was a challenge to really study and sort through the masses, but our tally was as follows:
196 Short-billed Dowitchers
~75 Semipalmated Sandpipers
57 “Eastern” Willets (plus one distant bird that may have been a “Western”)
~ 20 Black-bellied Plovers
~10 Semipalmated Plovers
4 Whimbrels (first of fall for me)
4 Least Sandpipers
2 Greater Yellowlegs
1 Lesser Yellowlegs
1 Ruddy Turnstone

At dead low, Biddeford Pool Beach was shorebird-free (which is often the case, as birds take advantage of the ephemeral mud and sand flats of The Pool and Hill’s Beach), but as we birded the neighborhood and Ocean Avenue, we picked up a few birds of note, led by 2 breeding-plumaged Red-necked Grebes. Three Black-crowned Night-Herons and a few migrant passerines such as two Eastern Kingbirds and an Indigo Bunting were also noted.

As the tide began to turn, we headed over to Hill’s Beach, and hit it perfectly! Here, the rapidly approaching water pushed birds towards us, and concentrated them in the highest spots for last-minute feeding. We were able to carefully and critically sort through each individual, checking for rarities and studying variation. Our effort turned up a few “good” birds, led by a trio of “Hendersonii” Short-billed Dowitchers (the prairie subspecies), a fairly-rare-but-regular stray to Maine.

The third bird we found, was the brightest of the lot, and was very obvious with its rufous coloration throughout its underparts.

The other two were quite a bit paler, so were a little tougher to tease out. I managed a crummy photo of one of them.

Another highlight was a single adult Stilt Sandpiper, along with an adult Red Knot. The complete tally was as follows:
119 Semipalmated Sandpipers
114 Short-billed Dowitchers (ssp griseus)
6 Black-bellied Plovers
3 SHORT-BILLED DOWITCHERS (ssp HENDERSONII)
2 Ruddy Turnstones
2 Sanderlings
2 Least Sandpipers
1 STILT SANDPIPER
1 Red Knot

So if the shorebird show was quite good, the tern show was simply great. At least a hundred Common Terns, including many begging juveniles were present, along with at least 30 Roseate Terns. A few Least Terns also joined the fray, including this adult standing watch on its fledgling.
