2018 Monhegan Spring Migration Weekend

The most abundant songbird throughout the weekend, a flock of 125 Cedar Waxwings would ball up each morning and then spread out through the island to feed.

My annual “Monhegan Spring Migration Weekend” battled highs seas (seriously, it was rough and we were all thankful it was only a 1-hr ride!) to arrive on the wonderful island of Monhegan on Friday, May 25^th. Five days later, I had two new birds for my Monhegan list, a total of 97 species including 18 species of warblers, and way too much of the best pizza in Maine.

After regaining our legs and equilibrium, we hit the ground running as always, birding our way to and from our hotel, lunch, and eventually dinner. No daylight was spared, and in doing so, we caught up with a few things, including the flock of 30 or so Red Crossbills, three of which perched nearby by close studies. Personally, however, I was most excited about 2 Eastern Bluebirds (at least one had been present for a while), my 210^th species on Monhegan! We had our first sighting of Warbling Vireo, which, like the 1-2 Field Sparrows – we saw everyday; both very uncommon on the island in spring. Apparently, I either started coming after – or perhaps only took better notes after – they last bred on the island. An island bird is a great way to start off the trip!\

Friday calmly eased us into the weekend, but Saturday blew us away. It was just one of those great days, with birds seemingly everywhere, and many of them low and easy to see. Following a moderate flight overnight on light westerly winds, there were a lot of new arrivals. Five Tennessee Warblers heard singing from one spot while tarrying at the Trailing Yew awaiting the coffee pot were a sign of things to come.

As is often the case on such flight days, we didn’t have to cover a lot of ground, as waves of birds were passing through the island and around town, pausing at just about every apple tree. It was hard to estimate the number of birds around, but there was a consistent south to north flow on the island, and several relatively-large flocks of the most common migrants of the day. I finally settled on 80 Red-eyed Vireos, 50 Blackpoll Warblers, and 20 Tennessee Warblers – impressive numbers of birds normally relegated to the tops of the highest oak trees, but today, more often than not, in low brush and short apple
trees.

While it wasn’t the kind of day that Monhegan legends are made of, it was one of the “good ol’ days” where migrants were plenty, views were crippling, and birding was easy. And all of that was punctuated by a few goodies, including an immature male Orchard Oriole, three Eastern Bluebirds together (two appeared to leave the island shortly thereafter), a lingering immature Great Cormorant, my first Common Nighthawk of the year fluttering off the high cliffs of White Head, 14 species of warblers including 4 Cape May and 2 Bay-breasted, and much more. And the day ended with two American Woodcocks heard calling and twittering from the lawn chairs of the Trailing Yew. That’s what Monhegan in migration is all about!

On Monhegan and elsewhere, a good birding rule of thumb is that if you see a blooming apple tree, you should look in it.

And that sunset from the Yew!

Not surprisingly, Sunday was slower, as light northeasterly winds precluded much in the way of overnight migration. And while it seemed that a lot of yesterday’s migrants had departed or melted into the woodlands, there were plenty of birds around, with a slight improvement in diversity, still plenty of Blackpoll Warblers, and a few highlights including a cooperative Green Heron, more Red Crossbills, a fly-by Black-billed Cuckoo, a Carolina Wren (finally; good to know one is here again), and a Northern Mockingbird (uncommon to rare out here) that we witnessed fly onto the island from behind, or perhaps over, Manana.

The afternoon was rather slow overall, but we just kept seeing birds well: the Warbling Vireo at eye level, a Lincoln’s Sparrow in the garden, and continued good views of Tennessee Warblers.

Monday the 28^th was the last day of the tour, and with a smaller group in tow, we covered a lot of ground. While there was virtually no visible migration on the radar overnight on very light easterly winds once again, there were clearly a lot of new birds around (or at least, birds not seen the previous days) and we ended up with the best diversity of the trip – 71 species by day’s end.
Sunday am

In fact, by days’ end, we added 14 new species to our cumulative weekend list – not bad for a “slow” day and the end of a tour. And there was some quality to it, too: a continuing very late drake Long-tailed Duck that we finally caught up with…
IMG_9570-edited-edited

…a Brown Thrasher, a Red-bellied Woodpecker, Sharp-shinned Hawk, and especially the Brant that we found on Nigh Duck – my 211^th all-time bird on Monhegan, and a new “island bird” for just about every birder on the island.

On Tuesday, it was just Jeannette and I on a one-day vacation, mostly on our own, but meandering in and out of contact with several friends on the island. We awoke to dense fog, but that rapidly lifted, and the strong (for the date) flight overnight produced another new arrival of birds. It sure wasn’t Saturday, but there were plenty more Blackpoll Warblers around, and warbler diversity overall was the best of the weekend with a total of 16 species, highlighted by the Mourning Warbler we found by the Mooring Chain, and an impressive 15 Blackburnian Warblers.

IMG_9833-edited-edited IMG_9844-edited-edited

…and we added a few new birds for the trip list including Great-crested Flycatcher, Northern Flicker, and had more species of butterflies today than total butterfly individuals all weekend, including an early Monarch. It was also a really, really nice day!
last-day_view

The afternoon was slower, and Jeannette and I winded down our visit with good conversation, one last slice (or two) of Novelty pizza and another pint (or two) of Monhegan Brewing beer, and caught up with some good friends who had just arrived with tours of their own. It was a relaxing finish to a great weekend, and the gentle boat ride home was more relaxing than we really needed before driving – just a little different than our outbound trip!

So yeah, it was a good trip. And, after one day at work, I am definitely ready to go back! At least I have two tours out here this fall. First, I have a full week with my WINGS tour, space on which is still available.

And there’s a little room left on our store’s annual Monhegan Fall Migration Weekend tour, which is only four months away!

beets
I forgot to take a photo of the pizza – I ate it too quickly as usual – so here are some beautiful beets from the Island Inn.

And as migrants were passing through, many of the island’s breeding species were well underway, such as this Song Sparrow gathering food for its nestlings.

Yellow-bellied Sapsucker, one of the more common and conspicuous migrants all weekend.

After spending what was probably the slowest week of birding I have ever experienced in fall on Monhegan with my WINGS tour a week prior, I was even more anxious to get back to the island. I know what this island can offer (well, besides great food, beer, and friends, that is)!

Because of ferry schedules, we added a new wrinkle this year, meeting for a birdwalk in Port Clyde before the mid-am ferry to the island (9/29). Golden-crowned Kinglets were particularly abundant and some Yellow-rumped Warblers were around, hinting at the amount of birds that arrived overnight. On the trip out, Northern Gannets were scattered about, and a flock of 7 probable American Pipits zipped by. When passerines are encountered on the ferry, as they return to the mainland, it’s usually a good sign that there are a lot of newly-arrived birds on the island.

When several Yellow-rumped Warblers were darting around near the dock, I thought it might be worth swinging into The Barnacle for a quick, early lunch so we could hit the ground running. And we are all glad we did, as it took us 2 ½ hours to walk from the dock to our lodging at the Trailing Yew!

It was fantastic…birds were everywhere. While it wasn’t a fallout with birds dripping out of the trees, every cluster of trees and bushes had some migrants in it. The “Cape May Spruces” on dock road hosted several Cape May Warblers and an immature male Pine Warbler – a rarity on the island. We soon tracked down a continuing Orange-crowned Warbler, and we slowly made our way through town, pausing at every apple tree and every weedy garden.

A lot had changed in the 5 days between my visits, with many more sparrows, and a much greater percentage of Yellow-rumped Warblers and both Ruby- and Golden-crowned Kinglets. Overall warbler diversity was down, but Yellow-bellied Sapsuckers were everywhere! The raptor show wasn’t half-bad, either.

I think I saw more birds today, even though we didn’t arrive until 11:30 than I did all week with my other tour! And 60 species by day’s end wasn’t too shabby either.

Friday night featured a very strong flight on the radar, but with a light winds becoming northeast after midnight, many fewer birds were around come morning (thanks to Hurricane Jose, this was the bane of our existence during the aforementioned tour), and the morning flight was very light. The afternoon was quite slow, but we continued to encounter new birds here and there. An unexpected surprise was a Wood Thrush calling at dusk. Although we never saw it, the calls are distinctive, and they were close by, and this was my 208th Monhegan bird (They’re usually long gone by the time I get here in mid-September).

Red-eyed Vireo

But this was only a fraction of the day’s excitement. First, a Bell’s Vireo was reported just as we arrived at breakfast. I thought about skipping the meal (it’s really a good bird if I consider passing on a Trailing Yew breakfast!) but after hearing about how chaotic it was (lots of owl calls and counter-productive tape use – tell me why a bird, exhausted from migration and without any hormonal urge to breed would come out in the open because you are playing an adult male’s territorial song? Especially when vagrants are often immature birds, the last thing they are looking for is a conflict; it’s amazingly ignorant…but I digress) down there, we decided to let the masses subside and fuel up for the hunt.

By the time we arrived, almost everyone had dispersed, and no sign of a Bell’s Vireo. But Pumphouse Road and the nearby yards were birdy, so we just started working the thickets. We had dispersed up and down Pumphouse Road, joined by several friends and fellow birders, including Kristen Lindquist and Bill Thompson. I was with just two members of our group, when a small flock of five or so vireos came in. There were three Red-eyed, but then I spotted what I thought could have been the Bell’s -a very pale, dull vireo creeping around the understory, with its tail cocked. With no one else around, I took off to assemble the group, and to get Bill to secure the documentation photos. When guiding, a bird doesn’t count unless the group is with you, so before I had anything definitive, I started running (only then remembering my ankle was still in a brace)!

Barb and Terez were still on what she thought was the bird in question, but as we all returned, it was clearly just a normally-pale, immature Blue-headed. Did I screw this up that badly? But wait, where was that 5th vireo?

I don’t remember who spotted it next, but when we did, it was clear it was not a Bell’s, but wow, that was pale. Like really, really, pale, and as we began studying it, we realized this may be even rarer!

At one point, I made eye contact with Marshall Iliff, and we both kinda smiled and nodded. We were on to something. Bill began to fire away. We watched. And then we began to discuss. And discuss. And at the brewery later, discuss some more. And the next day, yup, we were still talking about this bird. Almost two weeks later, as well.

Bill sent me his photos the next day, and on Sunday evening – at the brewery, of course, it’s where all great conversations occur – we realized that every single feature of this bird was consistent with Cassin’s Vireo, the member of the “Solitary Vireo Complex” that breeds in the west, and can be virtually indistinguishable from our regular Blue-headed. However, this bird had every feature perfect for Cassin’s, and as we sent around photos, everyone agreed that “if this isn’t a Cassin’s, then we can’t identify a bird as a Cassin’s.”

DullVireo3_edited-1 DullVireo4_edited-1

This would be the first record for Maine, and one of very, very few records for all of the East Coast. See, this is what a “slow” day on Monhegan should be like.

Anyway, back to the actual birding on Sunday. After only a surprisingly moderate flight overnight on light westerly winds, only a light morning flight was over the island, and it was almost exclusively Yellow-rumped Warblers. Increasing south winds helped keep activity reduced through the afternoon, when most of the group slowly departed on their respective ferries. We had great looks at the two continuing Dickcissels, more great views of Cape May Warblers, and finished the day off with the last member of the group by enjoying the long-staying Yellow-crowned Night-Heron at the Ice Pond.

L1100886-edited

It was just me and group-holdover John Lorenc on Monday morning, when Jeannette joined us for the day on the early Port Clyde boat. Her visit during my WINGS tour yielded fog and little else, so she was anxious to see and photograph some birds!

Interestingly enough, despite a rather light flight on the radar overnight (which really surprised me) on a light northwesterly wind, a strong morning flight developed come sunrise. As expected by the date, it was mostly Yellow-rumped Warblers, but there were many more kinglets and sparrows around. It was very busy before breakfast, and quite birdy – if rather homogenous – through lunch, with “new” birds scattered about. Even the early afternoon was pleasantly birdy, with pockets of activity here and there.

At least 4 Dickcissels were now present, and likely a new Clay-colored Sparrow. We had a fly-by of a Northern Pintail at Lobster Cove, one of very few records for the island. A calling Greater Yellowlegs, a flushed Wilson’s Snipe, and large flocks of southbound Canada Geese high overhead were among the additions to the weekend’s checklist.
IMG_6805-edited-edited
Two Dickcissels

When all was said and done, and Cassin’s Vireo was (fairly) confidently added to the list, a total of 89 species (including 15 species of warblers) were recorded in these four days, a respectable if not overwhelming total for a long weekend on the island.

And the food, beer, and conversation were great as always. And the butterflies, my goodness the butterflies. Monarchs were common, but Painted Ladies were downright abundant…

A Record-Shattering 5 Days at Sandy Point!

3 Replies

NOPA
Northern Parulas were certainly the “bird of the week” at Sandy Point.

It was a special five-day run at Sandy Point Beach on Cousin’s Island in Yarmouth. It was a record-shattering run in fact, in which I tallied nearly 18,000 migrants engaging in the “Morning Flight,” or “morning re-determined migration” when nocturnally-migrating passerines relocate (to drastically oversimplify things) come sunrise.
SandyPoint_sunrise,9-13-17

(To learn more about Sandy Point, check out the site entry in Birdwatching in Maine: A Site Guide, and for more on nocturnal migration, interpreting the radar, and the “morning flight” phenomena, check out Chapter 5 in my first book, How to Be a Better Birder. Whaddya mean you don’t have these two books!?)

I’ve had a handful of four-day runs, but I cannot think of a time when conditions were favorable – and I was actually present, and not leading tours on Monhegan for example – for five straight days. But I have most certainly never had five days like this!

I recorded 72 species “deemed migrating” through here, not including migrants that were in the bushes, such as the Gray Catbirds and Song Sparrows that are so abundant in the brush here. It does not include species like Osprey, in which some of the many I saw this week were likely southbound, but impossible to separate from the still-locals. And this tally did not include all of the waterbirds, from Common Eiders to herds of dabbling American Black Ducks, and from Bald Eagles to hunting Great Blue Herons, as well as resident species.

I tallied 25 species of warblers, including a single Connecticut Warbler, one of the most sought-after parulids in Maine. A Northern Mockingbird was only my 5^th ever noted here, and two passing Dickcissels are always a treat. But certainly the icing on the cake of this great week was the Lark Sparrow found by the group in the parking lot on the relatively quiet morning of 9/13. This was a first record for Sandy Point, and my personal 184^th species here.
LASP, Becky

But it was the morning of the 11^th that will go down in Sandy Point history! 8,185 migrants was not only a new record, but almost doubled the previous record (4,346 on Sept 21, 2010). It was incredible. More on that epic morning later.

A number of records for high counts for individual species were set, and I am sure even more would have been shattered if I had a higher rate of identification during the onslaught of the 11^th. Other trends, typical of the season, were evident, such as the slow but steady change in the composition of the flight. The early migrants like Magnolia Warblers were giving way to a growing percentage of Yellow-rumped Warbles and Blackpoll Warblers for example.

Now, let’s take a look at the radar. Here are the density and velocity images from 1am (as a sample) on 9/9 and 9/10. That’s a ton of birds on the radar.
1amRadar,9-09-17
1amVelocity,9-09-17

1amRadar,9-10-17
1amVelocity,9-10-17

And even as late as 4:00am on each day, a lot of birds were visible, and a lot of birds were offshore.
4amRadar,9-09-17
4amRadar,9-10-17

The night of 9/8 through 9/9 featured light westerly winds, shifting to northwest by sunrise. And on the next night, light north winds became northwest overnight. Both, as expected, produced great flights over and through Sandy Point some dawn.

Weather patterns, especially at this time of year, rarely produce three great nights for migrants in a row. And when they do, it often results in fewer birds overnight (and therefore at Sandy Point) come sunrise; essentially, the well temporarily runs dry.

And as you can see by the 1:00am radar image from September 11^th, the density was nowhere near the previous two nights, despite mostly light westerly winds overnight.
1amRadar,9-11-17
1amVelocity,9-11-17

And by 4:00am, it was rather quiet.
4amRadar,9-11-17

Light northwesterly winds in the evening slowly gave way to light north, before becoming light and variable. After midnight, they became west but didn’t really increase until after 2:00am. Coupled with a lackluster radar return, this was not a recipe for a huge flight.

Nonetheless with a light westerly wind at sunrise, I was heading to Sandy Point anyway. If only because it was a day off, and I won’t have many more chances to visit “my office” this month. A milky sunrise further clouded (sorry) my optimism for a big flight, but there were plenty of birds in the air.
Sunrise_on_big_day_atSP,9-11-17

And then all hell broke loose.

It was incredible. It was frustrating. It was beautiful. It was painful. It was amazing. It was indeed overwhelming, and at times, my only hopes at quantifying the flood was to skip attempting identification and just click my unidentified clicker as fast as I could.

And I really can’t explain it. It “shouldn’t” have been this amazing.

Come nightfall, with high pressure remaining in control, and with light westerly winds and clear skies once again, a moderate to strong flight occurred overnight. Here are the 1:00am and 4:00am radar images from the wee hours of 9/12:
1amRadar,9-12-17
1amVelocity,9-12-17

4amRadar,9-12-17

With light westerly winds come dawn, I was once again stationed at the bridge, and what was – prior to three days ago! – considered a very good flight passed over and through. It was even downright relaxing – and manageable – after the chaos of the previous morning. I had fun.

Not surprisingly, after four consecutive nights, the flight was much lighter overnight on the 12^th into the 13^th, as evidenced once again by the 1:00am and 4:00am images.
1amRadar,9-13-17
1amVelocity,9-13-17

4amRadar,9-13-17

And despite very light westerly winds in the morning, and clear skies, only a light flight was to pass through the point. Of course, that Lark Sparrow more than made up for it. It was also nice to enjoy a slower flight – and identify many more birds than not!

So almost every morning made sense: radar plus weather conditions correctly predicted the intensity of the flight. Except for one. The Big One. And I can’t explain it. But, I am OK (mostly) with that – it’s one of the fascinating and flabbergasting aspects of documenting the morning redetermined migration!

Winds turned to the south during the day on the 13^th, and continued light and southerly overnight, bringing the streak of five great nights of migration to an end. Come morning, I also slept in – relatively speaking – and then went for a massage. As my therapist began to work on my aching neck, she simply uttered, “Wow” and got to work. I felt the same on Monday morning when the greatest flight I have ever recorded passed through Sandy Point.

Species, such as this Swainson’s Thrush, that can be rather secretive in migration, are sometimes seen really well at Sandy Point!

Monhegan Spring Migration Weekend, 5/26-30/2017

OCWA_day5
Our group found a singing male Orange-crowned Warbler, one of the best birds of the weekend.

For the 7th year spring a row (fall tours since for over a decade), I spent my Memorial Day Weekend with a tour group visiting the magical and magnificent Monhegan Island. Exactly 100 species (including birds seen offshore during the ferry crossing) later – including 18 species of warblers – I was forced to depart, already counting down the days to my two fall tours (and perhaps making some plans for a summer visit…just because).

But the usually stress-free tour (compared to the logistics of much of the rest of my summer slate) got off to a rocky start (pun intended) with the early boat from New Harbor cancelling their morning trip late in the evening on Thursday. We made plans to head up to Port Clyde instead, and early in the morning, we received confirmation that all was well with the 10:30 am departure and we were reserved on it. Phew!

The whole group rendezvoused in Port Clyde, where based on the ride, well, let’s just say we were glad we were taking a big, heavy boat with a route that is sheltered for the first half. Because once we cleared the islands, well, things got a ‘rollin! But as always, the captain of the Monhegan Boat adeptly chose the route, and we basically tacked our way to Monhegan to avoid taking the swells on broadside. It was breezy enough that we were able to avoid the rain but remain in the fresh air outside on the stern (without diesel fumes), and we even spotted two Atlantic Puffins on the trip! But as for that small gull that was wheeling off in the distance just as we hit a trough and I hit John in my scramble for a view…well, we’ll never know.

Not surprisingly, the trip took longer than usual, but it allowed us to miss the rain! We arrived shortly after noon, with just a little lingering drizzle and mist. With diminishing northeast winds, we were prepared for worse, so we were fine with merely cool, only damp, and rather slow birding. Sure was better than steady rain and wind! And there were a few good birds to track down, led by the three Cattle Egrets that had been frequenting the island – my 206th species on the island, and a state bird for most of the group, at least. They were not hard to find, and were in fact pretty hard to miss for the better part of the next two and a half days. Really, until Jeannette arrived on Sunday, but that’s a story for a different day.

Good looks at Philadelphia Vireo, a very vociferous Sora, and a dusk vigil which resulted in very close encounters with Common Nighthawks rounded out a productive first day.

Eastern Kingbirds spent most of the weekend foraging low along the shoreline.

5/27: Day 2.
Well, that was a cold night in the rooms! Clearly the buildings of the island didn’t have a whole lot of ambient warmth built up, and extra blankets were at a premium. And with light northeast winds overnight, little to no migration was visible on the radar or in the dawn flight, but it was our first morning on the island, so we had a lot of birding to do.

A few pockets of migrants here and there slowly built up the checklist, with occasionally goodies including the Cattle Egrets, an immature male Orchard Oriole, a good look for most of a singing Mourning Warbler, and a fleeting White-eyed Vireo. We finally caught up with a female Summer Tanager (a bona fide one, not the female Scarlet with some missing feathers near the base of her bill), and we once again finished the day with feeding nighthawks, the incessantly calling Sora, and last but not least, a displaying American Woodcock.

In between, we feasted on delicious pizza at The Novelty, fueled ourselves with coffee at the Black Duck, and relaxed in the late afternoon with a beer at Monhegan Brewing (including ginger beer and root beer, too). Yeah, a slow day of birding on Monhegan is better than most days most anywhere else!

5/28: Day 3
With some people departing on Saturday, and others joining us for Sunday, we started Day 3 with a great find: A singing Orange-crowned Warbler right outside the Trailing Yew. Well, OK, it found us, and I’ll admit to taking way too long to identify it by sound with my pre-coffee and poor-night’s-sleep foggy state. Eventually, we had great looks at it, and those who were not yet with us were able to catch up with it later in the day or early Monday morning. This is a great bird in Maine in spring. In fact, it may have been my first in Maine in this season.
OCWA

Clearing skies and calm winds overnight allowed for an impressive migration, and the Orange-crowned was just the start of a great day of birding. The first half of the day was very birdy, with lots of new arrivals and new species. It was one of those mornings that were hard to break for breakfasts…but those breakfasts are all so damn good!

We found a second White-eyed Vireo, had unusually good looks at several Swainson’s Thrushes and Yellow-bellied Flycatchers, and slowly built up our triplist. It was a very good day, featuring a goodly total of 70 species.

5/29: Day 4
Light southerly winds at dusk had me optimistic as birds took to the air en masse come sunset. However, overnight, the winds shifted more easterly, shunting the flight inland, and overall, many more birds departed than arrived. With dense fog and a little mist come morning, my hopes for fallout conditions were dashed by the light to moderate easterly.

And accordingly, birding was very slow. I had a private tour for the first 2/3rds of the day, and we clawed our way through scattered small migrant flocks to find the goodies. There were definitely more Yellow-bellied Flycatchers around – including several unusually well out in the open. But the skies cleared up as the fog lifted, and we had a decent morning, a good part of which was simply spent exploring the woodlands of the interior of the island.

In the afternoon, Jeannette and I joined with several friends for some casual birding and conversation. Of course, once “off the clock,” my luck returned. After two of our friends had spent the weekend desperate for a good look at the Mourning Warbler, I walk by Donna’s lawn and calmly proclaim “umm, the Mourning Warbler is in Donna’s lawn.” We received permission to enter her yard, and followed it around the house for a while as it foraged around the foundation. This is not where I usually expect to see a Mourning Warbler, but we’ll take it. Unfortunately, all of Jeannette’s photos of it are of its butt.

Although it remained very slow overall, we had some really great looks at several birds we never did see on the tour, like a male Indigo Bunting, a Northern Waterthrush, and two very cooperative Olive-sided Flycatchers. We also caught up with the immature male Summer Tanager that was hanging out with the female and at least three Scarlet Tanagers – an impressive swatch of color and splendor, let alone offering good studies and comparisons.

And in the afternoon, after everyone else departed, Jeannette and I happened upon a female Bay-breasted Warbler at Fish Beach that needed some help. Several mealworms later (a new species for my fed-mealworms list!) she hopped off into cover to digest. And I am happy to report that by the next morning, she didn’t need any handouts as she was actively foraging on her own.

Jeannette and I enjoyed dinner at the Island Inn as our 24-hour vacation got underway, with Common Nighthawk, Sora, and American Woodcock serenading us on the way home.

Willets spotted earlier in the day by Jeannette and several others as they briefly alighted on the island.

Day 5: 5/30.
It was just Jeannette and I today, and with no visible migration on the radar and expansive fog, our main plans were to sleep in for a change – and for the last time for me until July! So we did not expect to be woken up by sun shining into our windows.

Not surprisingly, I popped up and outside, and began birding with another great look at the continuing Orange-crowned Warbler. There were not a lot of new birds around, not surprisingly, but with sun shining, birds were out at edges and easy to see. The female Bay-breasted Warbler was busy catching seaweed flies at Fish Beach, joined by a companion male Blackburnian Warbler and later, a young male American Redstart.

We finally saw a Bald Eagle after five days on the island, and 4-7 Great Blue Herons dropped in for a visit. It was extremely quiet after breakfast, but again birds were just pleasantly visible in the sun, especially in blooming apple trees. Things like the Eastern Kingbirds, which spent most of the weekend feeding in and around patches of seaweed on the beaches were up and about, flycatching “normally” from treetops. We also slowly padded the triplist, with a Yellow-bellied Sapsucker (incredibly, the first woodpecker of my five days here – how did I miss the resident Downies?) and great look at a Yellow-billed Cuckoo (my first of the year, and later, a very good look at a Black-billed as well). The male Summer Tanager, at least, continued to frequent a feeding station, and a Garter Snake was my third snake of the weekend (Smooth Green on a couple of occasions, and a single Red-bellied on Monday morning).

A little wave of presumed migrant swallows increased the number of Barn and Tree Swallows by 2-3 each, but also including 3 Bank and 1 Cliff Swallow, the final two new species of our stay.

The afternoon was quite slow otherwise, but admittedly, we spent a decent portion of the last couple of hours of the afternoon involved in conversation at the brewery, and about everywhere in between.

But alas, it was time to go, on the late boat back to Port Clyde. We said our goodbyes, for now, wondering if we’ll be back next spring (depending on if that misguided wind project gets underway), but also how soon we can get back this summer!
departure,5-30-17_edited-1

While we didn’t have any puffins – or any other seabirds – on our smooth ride back, we did have a couple of Roseate Terns as we approached Port Clyde. And then it was time for the drive home, and back into entry into the real world!

Just a typical Memorial Day Weekend full of birders on Monhegan!

Gray-Cheeked Thrush, Hooded Warbler, and Other April Rarities thanks to this Storm.

3 Replies

While outdoor enthusiasts, those with yardwork to do, Zane at the Bradbury Mountain Spring Hawkwatch, and many others bemoaned the coastal storm that made for inclement weather from Tuesday through Friday morning, birders from the Mid-Atlantic to Nova Scotia were gearing up.

With the large (if not overall strong) area of low pressure riding up the Atlantic seaboard in late April when numerous species are now on the move, “Rarity Fever” symptoms were reported widely. As if recent “Megas” like Vermillion Flycatcher and Fieldfare here in Maine weren’t enough to stoke the fire, friends in Cape May began posting their “wish list” of possibilities. Storms such as these, sometimes called “slingshot” events can deposit birds further north than usual, facilitate the arrival of record-early migrants, and perhaps produce some astounding vagrant.

This far north, I simply had daydreams of southern “overshoots” that occur in most years – but especially following such storm systems – such as Blue Grosbeak, Summer Tanager, and Hooded Warbler. But I also started thinking about things from further afield like Swainson’s Warbler, all sorts of terns, and maybe even something from even further away like a South American Fork-tailed Flycatcher who overshot its goal and then got caught up in the system. Maybe a Magnificent Frigatebird? Or perhaps something else on one of my predictions lists for next birds for Maine, and myself.

While weather isn’t truly the ultimate cause of many vagrants, it certainly facilities their arrival in far-flung places. And weather can certainly impact migrants and displace them slightly further afield than they usually range. And storms like this, moving out of the Bahamas, strengthening in the South Atlantic Bight, and marching up the coast has quite a history of producing some great birding. (I wrote more in depth about some of these factors and causes of vagrancy in Chapter 4 of my first book, How to Be a Better Birder).

Here are the wind maps and surface maps from Tuesday through Thursday.

So, I cleared my schedule, kept an eye on the listserves to our south during the rain on Wednesday, and hit the field on Thursday, starting at Biddeford Pool. A few years ago, one similar (but stronger) storm system yielded a Summer Tanager, Blue Grosbeak, and Hooded Warbler in the neighborhood, and I had similar hopes for this morning.

I got really excited when one of the first birds I saw was a Magnolia Warbler (very early, perhaps by as much as 10-14 days!). Surprisingly, it was the ONLY warbler I saw all morning, and its early arrival is undoubtedly related to the storm. My first House Wrens were right about on schedule, however, and my first Veery was only marginally early.

However, in the same yard on Third Street, and loosely associating with said Veery, was not a bird I expected at all! In fact, I have a rule that I like to instill on my birdwalk participants: if it’s April in Maine and you see a dark-spotted Catharus thrush, it IS a Hermit Thrush. This was the exception to the rule.
L1090495_GCTH1 L1090520_GCTH3

There’s no doubt it was either a Gray-cheeked or a Bicknell’s Thrush, but those birds can be very challenging to ID. Generally very secretive in migration, getting good looks – let alone good photos – is often impossible. And neither is expected to be walking around front yards in a neighborhood!

It is also incredibly early, as neither of these species is usually detected in Maine (if at all, especially Gray-cheeked) until the third week of May, and sometimes not until even later. This was beyond early, and certainly suggests its arrival here was at least partially influenced by the storm system.

The overall cool gray appearance without any hints of reddish-brown anywhere (no matter what light angle I viewed it in) immediately suggested Gray-cheeked Thrush, but the date and circumstances warranted careful study. I even posted the photos online, sent them directly to friends, and added them to at least one forum, hoping for additional feedback.
L1090565_GCTH6

However, other than the seemingly “dumpy” shape of the bird, nothing here suggests Bicknell’s Thrush to me. There’s just nothing warm anywhere in this bird’s plumage, and the cheeks are finally streaked gray, not more even washed warmish-brown as in most Bicknell’s. There’s no contrast within the wings, or especially between the uppertail and the rump, either.

Although this bird’s bill is fairly extensively pale, it isn’t as bright yellow as many Bicknell’s – although I can admit to not really being a fan of this fieldmark – and even has a hint of pinkish.

In other words, as several commenters mentioned, this really looks like a “classic” Gray-cheeked Thrush, with perhaps the appearance of a smaller size and more compact shape suggestive of the subspecies minimus that breeds mostly in Newfoundland and Labrador (it’s also the subspecies whose breeding range makes the most geographical sense to appear in Maine in spring). Of course, without measurements or vocalizations, there is still a little tinge of doubt in coming to a conclusive identification.

Now, a Bicknell’s Thrush, wintering somewhere in the northern West Indies or perhaps Cuba, beginning its trek to the mountains of the northeast, could have been entrained or “slingshot” by this storm. In fact, it would make a lot of sense. But Gray-cheeked Thrushes winter mainly in northern South America, and head north through Central America. That route would not seem to be effected by this storm. Perhaps it’s just a coincidence, and the storm was only a proximate cause of its arrival in Biddeford Pool.

Anyway, elsewhere in Maine, a White-eyed Vireo was in Cape Elizabeth (present through Friday) and a Summer Tanager was reported in Southwest Harbor. Early migrants included a Scarlet Tanager in Ogunquit and one found deceased in Cape Elizabeth, along with a few scattered Indigo Buntings as far inland as North Yarmouth.

Meanwhile, to our south, birders in Cape May had a White Ibis (and, even more excitingly, a –our!? – Little Egret, a first state record that may not have anything to do with the storm); a Red Phalarope and a smattering of birds just beyond their normal range, such as Summer Tanager, were in Manhattan, and a Kentucky and Yellow-throated Warbler were on Cape Cod among some of the widespread reports of “early” migrant arrivals.

During the day on Thursday, the low pressure system continued to weaken and dissipate over the Gulf of Maine, with a snotty easterly and drizzly onshore flow continuing. A weak, slow-moving cold front finally cleared things out mid-day on Friday.

In the dense fog on Bailey Island in Harpswell early Friday morning, I found pockets of migrants (mostly Yellow-rumped Warblers and White-throated Sparrows) but also several surprises, led by 1 male Hooded Warbler and a White-eyed Vireo, both along Elden Point Road – the kind of southern “overshoots” we have come to expect here in Maine from these type of storms.
L1090659_WEVI,BaileyIsland,4-28-17_edited-1

There were quite a few other migrants around, as well. A total of 9 Blue-headed Vireos included a flock of 6 together, and there were scattered other migrants such as Ruby-crowned Kinglets, Hermit Thrushes, and Savannah Sparrows.

An early Yellow Warbler was also present, as were marginally-early (based on the current progress of the season) included 1 Common Yellowthroat and 1 Great-crested Flycatcher, while other personal FOY’s included more on-time Black-and-white Warbler (7) and Ovenbird (1-2). 11 Palm Warblers were my seventh species of warbler on the morning (plus Pine Warblers singing at home).

Elsewhere, another Hooded Warbler was found at Timber Point in Biddeford, and smattering of other early migrants included a Warbling Vireo on the Eastern Promenade (where a goodly number of birds were reported in the fog this morning)

I can only imagine what might have been found if every peninsula and island was covered over the past few days! So, with more birders hitting the field this weekend, and more people home from work to check on their feeders, I wonder what will be found. Maybe a Painted Bunting at a feeder? A Purple Gallinule in a marsh? But you know what I would like the most? A Swallow-tailed Kite over Bradbury Mountain during my hawkwatch workshop as part of the annual Feathers Over Freeport events!

2016 Rarity Season Part I

3 Replies

In my last blog, I predicted some great birding was in store for us here in Maine. Our entry into “Rarity Season” coupled with an active weather pattern was undoubtedly going to make for some exciting birding in the near future. It certainly started off with a bang!

Immediately following the Nor’Easter that drenched us on Friday, October 28th…

…a Sabine’s Gull was discovered on Sabattus Pond.
l1080338_sagu1_edited-1 l1080346_sagu2_edited-1
l1080280_sagu3_edited-1

This gorgeous gull was my 373^rd species in Maine, and while I knew I was going to see one sooner than later, I expected to finally get one in Maine waters during my Washington County Weekend tour (we were close!), and not well inland on a small lake!

Whether blown inland by the strong winds or “grounded” as it cross-cut over land, this pelagic is not what one expects while scanning the ducks at Sabattus. An early 1^st Winter Iceland Gull (later, two), and a rare-inland sweep of all three species of scoters (9 Surf, 4 Black, and 1 White-winged) were all related to the weather as well.
l1080288_icgusabattus10-29-16_edited-1

Similarly, an adult Black-legged Kittiwake out of place in a pond at Fortune’s Rocks Beach on Sunday was likely storm-related. Although regular to downright common offshore, this is not a bird we usually see onshore in southern Maine.
l1080409_blkifortunesrocksbeach10-30-16_edited-1

One can only imagine what else was on the 2,600+ lakes in the state of Maine during and immediately after the storm! Jeannette and I did check a few spots around Sebago Lake on Halloween, but it was surely too long after the storm, and the only birds of some note we turned up were single Dunlin and Black-bellied Plover (fairly rare inland, especially this late) at Raymond Town Beach.

I bird hard this time of year, doing my best to finish projects and keep my schedule as clear as possible to afford as much time in the field during these fruitful weeks. While I skipped birding in Portland, I did cover a lot of ground, and searched for odd birds in odd places, as well as focusing on the seasonal “migrant trap” hotspots.

In doing so, I found a few good birds, including this Lark Sparrow (always a treat away from Monhegan) at Pott’s Point in Harpswell on 11/10:
lasp1pottspoint11-10-16-edited

As for wayward vagrants seen around the state by others, there were quite a few from the south: a Blue Grosbeak in Portland on 10/31, a couple more Yellow-breasted Chats were found here and there, and most surprisingly, a Blue-winged Warbler in Saxl Park in Bangor on November 7^th – this early migrant simply has to be a reverse-migrant or 180-degree misoriented migrant from points south; right? And the headlines, from the southwest, as a Cave Swallow reported from Cape Elizabeth on the 12^th.

From the west (and/or mid-west) came a Clay-colored Sparrow at Two Lights State Park on 11/6 and a few scattered Dickcissels around the state (but where are the Western Kingbirds this year?). A Cattle Egret in South Thomaston on 11/6 and another in Pittston on the 13^th could have come from either direction.

But it’s not just rarities that make this time of year so much fun. There are all of the regular migrants that are still “lingering.” Some of the late birds that I have seen in the past weeks included a Red-eyed Vireo along the Saco Riverwalk and 1 Semipalmated Sandpiper at Biddeford Pool Beach on 10/30, a Red-eyed Vireo at Sandy Point on 11/1, a Pine Warbler and a late-ish Winter Wren on Bailey Island in Harpswell on 11/4, a slightly tardy Yellow-bellied Sapsucker with Jeannette at Beaver Park in Lisbon on 11/8, a Turkey Vulture over Falmouth on 11/11, two Winter Wrens on Peak’s Island on 11/14, and a smattering of Hermit Thrushes.

Other birders also reported the usual slew of truant migrants, such as a smattering of Baltimore Orioles, a couple of Scarlet Tanagers, and a decent variety of late warblers here and there. There’s still a Marbled Godwit, 4 American Oystercatchers, and 2 Red Knots at Hill’s Beach in Biddeford Pool; I enjoyed them on the 30^th, but they continued to be reported through at least 11/2 with the godwit still being reported as of 11/12! A few Long-billed Dowitchers were reported, with the one at Sabattus Pond on 11/5 being at the most unexpected location.

The winner, however, is the immature female Ruby-throated Hummingbird that appeared at a feeder on Cousin’s Island in Yarmouth on November 10^th! I viewed it the next morning and it continues through today, the 14^th. Although the photos taken by the homeowner looked good for “just” a Ruby-throat, I hoped I was missing something from the still images. Any lingering questions/hopes I had were dashed however.

That being said, it’s still a great record. Through our store we have been promoting keeping up hummingbird feeders into November for over a decade, and our database of observations after early October is growing. When I first got a call yesterday, I was sure this was going to be “a good one.” It was Nov 10th after all!

Amazingly, this is the same house that hosted a Selasphorus hummingbird last fall! In other words, it sure does pay to keep those feeders out, even if it’s “just” a Ruby-throat!

Other, more seasonal, highlights for me over these two weeks included the following. Jeannette and I had 100 Horned Larks along Mayall Road in Gray/New Gloucester on 10/31; 18 Snow Buntings and 13 Horned Larks flew over Bailey Island on 11/4; a Lapland Longspur with 6 Horned Larks were at Stover’s Point Preserve in Harpswell on 11/10; two Ruddy Turnstones were at Winslow Park in Freeport on 11/12 with the Saturday Morning Birdwalk group – one of only two or three places in the state we regularly see them during the winter.

l1080470_badobaileyisland11-4-16_edited-1
This Barred Owl on Bailey Island on 11/4 was a treat. Any day with an owl is a good day!

Meanwhile, the new arrivals – including many species that will be spending the winter with us – continue to arrive, my “first of seasons” this week included 2 Common Goldeneyes at Sabattus Pond on the 29^th, 2 “Ipswich” Savannah Sparrows at Timber Point in Biddeford on 10/30…
l1080390_ipsp1timberpoint10-30-16_edited-1

…lots of Horned Grebes arriving all over, 2 Harlequin Ducks at East Point in Biddeford Pool and 3 Purple Sandpipers at Hill’s Beach on 10/30.

l1080426_sand_and_dunl1biddpoolbeach10-30-16_edited-1
There were also plenty of Dunlin and Sanderlings around this week, such as this one Dunlin nestled amongst the Sanderlings on Biddeford Pool Beach on the 30^th.

Waterfowl migration is in full effect, and not just at Sabattus Pond (although that is certainly one of the top spots in the state). Scoters, Long-tailed Ducks, Red-breasted Mergansers are all piling in, and dabblers are also on the go, such as the single drake Northern Pintail and American Wigeon at Great Pond in Biddeford on 10/30. Common Mergansers are also now arriving; I saw my first migrants at Sebago Lake on 10/31.

Jeannette and I visited Sabattus on a gorgeous, warm day on the 8^th, with glass-calm conditions allowing for careful combing through the masses: 649 Ruddy Ducks, 510 Mallards, 176 Lesser and 119 Greater Scaup, 104 American Black Ducks, 73 Buffleheads, 69 Hooded Mergansers, 40 Common Mergansers, 13 Northern Pintails,11 Common Goldeneye, 8 Green-winged Teal, 5 White-winged and 1 Surf Scoter, 4 American Wigeons, 4 Common Loons, and a very-rare-inland Red-necked Grebe.

On 11/13, I returned with a Birds on Tap – Roadtrip! tour with our partners at the Maine Brew Bus. Although I didn’t count everything as carefully as I do when on my own, “Fall Ducks and Draughts” did record 600+ Ruddy Ducks, 3 Gadwalls, AND 2 White-winged Scoters amongst the 14 species of waterfowl present.

The “Greater Yarmouth Goose Fields” have been slow this year so far, likely also due to the mild weather and lack of early snowfalls to our north. In fact, the only “good” goose so far has been a “Blue” Snow Goose that showed up during the week of October 17^th continuing through at least 11/11. Canada Geese numbers remain rather low however; I have still not surpassed even 600 total birds this season.

There’s still some passerine migration a’happening, as well. For example, my last two days at Sandy Point for the season yielded 221 birds on 10/31 (led by 123 American Robins and 18 American Crows) and 131 on 11/1 (led by 59 Dark-eyed Juncos and 44 American Robins). Common Grackles and a smattering of Red-winged Blackbirds are still heading south, although their numbers are greatly reduced over the past week.

Sparrows also continue to move through, with lots of Dark-eyed Juncos and White-throated Sparrows on the move, and my first American Tree Sparrow arriving at the Yarmouth Town Landing on 11/5 during our Saturday Morning Birdwalk, followed by more as the weeks progressed. A White-crowned Sparrow at Biddeford Pool on 10/30 was getting late, but there are still scattered Chipping Sparrows here and there as usual, including one still here at the store’s feeders.
cistmontanus_type_dejuyard11-6-16 cistmontanus_type_deju_yard211-6-16

This junco on our back porch on November 6^th appears to be of the inter-mountain subspecies/hybrid swarm often labeled as “cistmontanus.” It’s definitely not a pure “Oregon” Dark-eyed Junco, and the curved hood with buff of the sides traveling up to below the fold of the wing, however, suggest that this is not a pure “Slate-colored” Junco either.

And speaking of feeder birds, a recent spate of Evening Grosbeak reports (I have heard or seen several 1’s and 2’s recently, but 6 were at Old Town House Park on 11/3), along with an uptick in Purple Finches and Pine Siskins are suggestive of a decent winter around here for at least some of the finches. I also had a few single Red Crossbills fly over in a handful of locations recently. And the first Northern Shrike reports have started trickling in.

But overall, we’re off to a fairly slow start to the November Rarity Season. My guess is the lack of cold fronts early in the fall ushered fewer birds east (e.g. Western Kingbird) but also it remains fairly mild. I’m just not sure birds have begun concentrating yet in places that birders find them (like coastal migrant traps, city parks, etc). But as temperatures continue to drop, this might change. Afterall, after a very slow November last year (also very mild), December was simply incredible.

As the shorter days get colder (maybe), I would expect more birds to begin turning up, especially at feeders and along the immediate coast. The coming weeks always produce something remarkable.

wind-map-11-11-16
A blast of cold, Canadian air finally arrived this past weekend, as evidenced by the wind map of 11/11.

However, it might be hard to top the incredible and unprecedented White Wagtail that showed up in Rye, New Hampshire on 11/2 through early the next. You know I’ll be trying though!
