2025 Monhegan Fall Migration Weekend Tour Report

An American Bittern sitting in the open in a tree, just a handful of yards away could have easily been the highlight of any birding weekend. But, this stellar start was just the tip of the iceberg of the weekend’s birding excitement.

It has been quite a few years since we had a weekend like this. Lots of birds, “mega” rarities, warm weather, and tons of excitement. It was truly a special weekend. We were honored to have been there for it.

The tour began on Friday, with only one participant joining me on the Hardy Boat. The island greeted us with a Lesser Black-backed Gull, which we scoped from the wharf, and several warblers at the usual spot uphill. But after getting the inside scoop from birders already on the island, we made a bee-line for the Ice Pond where an American Bittern was sitting all morning. Remarkably, however, it was sitting in a bush (see above)!

How’s that for starting a tour off right? We also immediately encountered Dickcissel and Blue-gray Gnatcatcher, and there were plenty of Yellow-rumped Warblers and Palm Warblers here and there.

After lunch, with our group now complete, the surprisingly good birding continued. Despite such a warm afternoon and few birds on the radar overnight on mostly a southwest wind aloft, we enjoyed an excellent introduction to Monhegan birding in the fall:  2 Clay-colored Sparrows with 2 immature White-crowned Sparrows, a Dickcissel, and several White-throated Sparrows in one field of view; a dozing Common Nighthawk trying to stay camouflaged on a wood pile, and another visit to the still-confiding American Bittern at the Ice Pond for those who arrived later. It was a solid afternoon overall, with bird activity continuing right up until dinnertime.

Cape May Warblers in a wide variety of plumages is always one of the highlights
of any fall weekend on Monhegan

.Unfortunately, our best bird of the day was almost the one that got away. Almost! While viewing an Indigo Bunting in the Community Garden, a second bunting snuck into view, skulking. It briefly popped out, and I yelled “get photos” and then it popped back into the weeds and was not to be seen again.

“Did I see green?” I exclaimed, but it was so fleeting, and the light was so harsh, and the bird was so, so pale, I couldn’t be sure. I looked at photos on the back of cameras in the sun, and we had a good discussion on why this could have been a Painted Bunting. Unfortunately, I have little experience with first fall female (presumably) Painted Buntings and had no idea they could be this unbelievably drab. So I talked myself out of it.

Overnight, I received photos from Bill Thompson, who, an hour or two after we saw the bunting, also briefly saw and photographed it. “Is this a Painted Bunting?” he asked.

Yup, that really does have green on it, and on more than one side – in other words, not a reflection. Darn it. It counts for us – we all saw it – but in hindsight, we should have gotten the word out about a “possible/probable” Painted Bunting and had more eyes looking. Luckily, Bill was in the right place at the right time once again! But I felt like I had blown this one. I was too quick to dismiss it and so I decided I would have to make up for it over the rest of the weekend. Maybe the dry cold front that passed through on Friday evening and shifted the winds would help.

A very strong flight Friday night into Saturday morning on a diminishing northwesterly wind was idea for bringing birds to Monhegan Island come sunrise. And at first light, it was clear it was on!

The Morning Flight featured tons of Yellow-rumped Warblers with the occasional Palm and Blackpoll Warbler. Between the morning flight and our pre-breakfast stroll, we had a lot of birds: a couple of waves of Dark-eyed Juncos, bunches of Red-breasted Nuthatches, more Golden-crowned Kinglets and Purple Finches, insane views of Peregrine Falcons, 2 Dickcissels, 4 Baltimore Orioles, and lots of great views of lots of common species.

After breakfast, it remained fantastic. Just birds everywhere, and not surprisingly, some notable species began to be turned up.  Our first “chase” was a Yellow-throated Warbler, our group arriving just in time before it took off.

Luckily, Dan Gardoqui and I stumbled upon it again while foraging for lunch, and I was able to round up several of the group members for improved views and photographs.

The American Bittern was now in the marsh, there were now three Dickcissels, 8 Baltimore Orioles, and a second, but definitively identified Indigo Bunting. No green one, unfortunately.

Not surprisingly on such a nice day, the afternoon was slower, as birds had departed the island early, or had now sought refuge in the shadows, especially with the continuing activity of Peregrines, Merlins, and Sharp-shinned Hawks. So, we checked some nooks and crannies, turning up a Nelson’s Sparrow at Lobster Cove and enjoying gliding Peregrine Falcons passing right in front of us from Burnt Head. We also took the time to enjoy butterflies, plants, and all other walks of life.

It was a delightful afternoon, but we returned to town to find we had missed out on a Western Kingbird. Luckily, a few of us caught up with it at dusk when it was refound near the Mooring Chain.

(phone-binned photo under low light)

So, it was a great day, and given the winds and weather, we expected it to be such. Then, with little to no movement overnight (at least visible on the radar), on a light south to southwest wind, we hoped for some birds to stick around from Saturday and perhaps be augmented by a rarity or two. At the very least, I wanted to show the Yellow-throated Warbler and Western Kingbird to the rest of the group, especially with a big turnover in participants for the second half of the weekend.

What we didn’t expect was to run out of superlatives before breakfast. We certainly did not expect it after viewing the Morning Flight, which consisted of exactly one American Pipit (and the big wandering flock of Cedar Waxwings, of course).

Once again, a bird was identified from photo review (what did we do before Instant Replay?!) and Bill Thompson and Jess Bishop had apparently discovered a Mega rare Bell’s Vireo on Saturday with only 4 accepted previous records for Maine. With such a slow morning flight, I decided to mix things up from my usual routine, head clockwise through my usual dawn loop, and give it a try to find the Bell’s. We stopped near where it was seen on Saturday, and chatted about the rarity, the identification, etc. “Holy shit, there it is!” I tried not to exclaim too loudly as the bird popped out right in front of us.

We observed it for about 10-15 minutes as it popped in and out of a brushy edge, focusing on feeding in young cherry trees with fall webworm clusters. Birders began to arrive from all directions, as the vireo kept coming in and out of view before flying right over our heads and disappearing deep into a dense thicket.

I’ll steal Bill Thompson‘s (with permission of course) Bell’s Vireo
from this morning since he was standing next to us.

It was getting too crowded for our tastes, so we moved on and let others have the edge to monitor. We enjoyed Cedar Waxwings, Northern Flickers, and then took a moment to pause at our usual starting spot, at the spruces behind the Yew.

It was slow, and quiet, and so I was making sure we looked at everything, like the one solo warbler flying towards us from across the sky over the Trailing Yew. It then landed a short distance away, and I brought my binoculars up to it, assuming we had a close Yellow-rumped Warbler to talk about.

<expletives deleted>

A Black-throated Gray Warbler, with only 5 previous records from Maine, was there. Right there. We had some great looks and photo ops, called over a friend, and then watched it the herd of birders arrive and head out to follow it. What a lucky find! We were ecstatic. And we still hadn’t had breakfast! (See photos from tomorrow),

Wondering if the day could get any better – and pretty content if it did not – we reconvened after breakfast and headed in the opposite direction from the searching masses, as I am wont to do.

It worked again: we found one Lark Sparrow, and then another. How many Clay-colored Sparrows – 4? 8? More? An Orange-crowned Warbler at the Ice Pond, a fly-over Red-bellied Woodpecker, a Pine Warbler, a Yellow-bellied Sapsucker on every tree. So much for it being a slow day.

Another warm afternoon sent us into the woods for shade, immersing ourselves in a cacophony of Red-breasted Nuthatches, sprinkled with Golden-crowned Kinglets, and the occasional Red-eyed Vireo or other migrant. We took in the Fringed Gentian, the scenery, and finished strong with the 2 Lark Sparrows and 4 Clay-colored Sparrows together.

Today was a good day.

Monday, the fourth and final day of the tour began with excited anticipation with another strong flight overnight on a diminishing NW to W wind. But today, it was just too nice, and a lot of last night’s birds passed overhead resulting in just a light Morning Flight come sunrise. But there was a turnover of birds, and our morning walk added several things to our list including the Eastern Kingbird we finally caught up with, and another Orange-crowned Warbler. The highlight, however, of our pre-breakfast jaunt was a juvenile Sharp-shinned Hawk that flew to a spruce, plucked a cone off of an outer branch, and then proceeded to play with it! It would move it from its bill to its talons, and then it dropped it, chasing it down the tree. It then flew back up and grabbed another! What a remarkable insight into how a kid Sharpie gets better at hunting on its own.

After breakfast, the good Merlin show of the day continued, and we took time for a short gull identification workshop. Our first Ring-billed Gull out here was good to practice on, and we conveniently had three Lesser Black-backed Gulls: an adult and 2 first-cycle birds. But mostly, we worked through the difference between each age class of the common Herring and Great Black-backed Gulls.

We finally picked up a Northern Waterthrush- our 20th species of warbler on the weekend! But otherwise, it was pretty slow.

It was slow in the afternoon, too, but the Black-throated Gray Warbler had been refound just before we reconvened after lunch, and eventually we were all treated to much, much better views and photo ops than the morning before.

We then twitched a rare Common Buckeye butterfly and Lady’s Tresses orchids.

 Our last new species of the trip was one of the last birds we observed together: a Yellow-billed Cuckoo eating American Dagger Moth and/or Hickory Tussock Moth caterpillars. Watching it whack the caterpillar on a twig to beat off its irritating hairs, we had another moment of insight into a bird’s world.

With the tour now complete, Jeannete and I enjoyed a delicious sunset and delightful food with friends and spotted an American Woodcock on our walk back.

And finished with another meal of Monhegan indulgence.

As usual, Jeannette and I then spent our Tuesday off together on the island. After a light morning flight, but another turnover of birds, we decided to spend most of the morning in the woods, ostensibly looking for a previously reported Black-backed Woodpecker. But mostly, we wanted to take a hike along the island’s less-visited north end. We added Winter Wren and an Ovenbird to our weekend list, enjoyed the silly amount of Red-breasted Nuthatches, and encountered several pockets of White-throated Sparrows and Dark-eyed Juncos. Later, after lunch, we ran into a Black-billed Cuckoo, and a Spotted Sandpiper at the dock turned out to be our 100th and final bird of a truly exceptional weekend on Monhegan. We already cannot wait to return in May!

2023 Down East Adventures Birding Tours.

Freeport Wild Bird Supply is very excited to partner with Down East Magazine’s Down East Adventures for our third year. In 2023, we are expanding our offerings to include two exclusive overnight trips, along with our popular ½- and whole-day targeted workshops.  Focused on skill-builder rather than list-building, there will be plenty of “life birds,” but also more knowledge and education about birds, habitats, birding, and much more about the natural world.

The full list of upcoming tours can be found here.   At the conclusion of each tour, I’ll post the trip report here.

  • Winter Waterbirds Workshop, January 15.

This Purple Sandpiper was about as cooperative as it gets for us at Sohier Park in York.  Later, it was joined by its friends (photo below).  This is really a lovely shorebird when viewed as well and as close as we experienced.

Extremely strong winds and very high seas presented a challenge as we sought out wintering waterbirds along the southern York County Coast. We worked hard to find sheltered water where we could observe birds well, but when we did find that secluded cove, peninsula lee, or rivermouth, we were treated to incredible looks at many of the birds we had hoped for.

We looked down on Red-breasted Mergansers at Perkin’s Cove, and you’ll never be closer to a Common Loon than we were at the Ogunquit Rivermouth. We checked a few more locations than I usually need to on this tour, but our most productive spot was the southern shoreline of Sohier Park at The Nubble. There, we were treated to close views of Black and White-winged Scoters, Harlequin Ducks, and a most-cooperative flock of Purple Sandpipers.  We then ended the day at hidden Abbott’s Pond, where we enjoyed a break for the wind, close comparisons to study details between Mallards, American Black Ducks, and hybrids thereof. 

Meanwhile, a group of 8 or so Black-legged Kittiwakes were feeding off of Short Sands Beach, and a stunning adult Iceland Gull passed by at The Nubble. Unfortunately, the seas were just a little too rough to find any alcids today, but we knew they were out there!

  • Spring Migrant Songbirds Workshop, May 14.

This stunning Blackburnian Warbler nicely demonstrated the value of blooming oak trees for seeing warblers in the middle of May.

Four hours later we had not left Evergreen Cemetery in Portland…a very good sign. There was just no need to move along, the birds kept coming to us. In the end we tallied a respectable 16 species of warblers, even though growing a list was not our goal. What made this workshop successful, however, was how well we saw just about all of the warblers and other songbird migrants throughout the morning.

Warblers were a highlight of course, including repeated quality time with favorites such as American Redstart and Black-and-white Warblers, the two most plentiful migrants this morning. We also enjoyed great looks at several Chestnut-sided Warblers, Magnolia Warblers, and Northern Parulas, with fantastic studies of Black-throated Blue Warbler, Black-throated Green Warbler, Yellow Warbler, and Wilson’s Warbler. We also saw two newly-arrived Tennessee Warblers which aren’t always easy to get looks at. There was a good amount of song this morning, so we had chances to listen and learn many of these species as well.

Shortly after hearing a Red-eyed Vireo and my describing it as “high up and often hard to see,” we found one in the lower branches of a nearby oak, and watched it sing, forage, and do all things vireo for almost 10 minutes!  Likewise, after hearing distant Ovenbirds, we had two walking around right in front of us! Beginning with a view of a Veery on the ground in the open, we saw it again as the walk ended, only a few feet in front of us for another great view and chance to observe and study.

During the morning, we chatted about migration, habitat, and the process of building the necessary toolkit to build birding skills. Finishing the walk with a quick overview of some references (we had too many birds to leave much time for anything more), we recapped a very productive and instructive morning of spring birding.

  • Rangeley Birding Workshop, June 6-8.

Our first overnight tour together, the Rangeley Birding Workshop was based at Bald Mountain Camps in Oquossoc, nestled on the shore of Mooselookmeguntic Lake. Common Loons greeted us, but so did the rain. June of 2023 was one of the rainiest Junes on record in Maine, and we were very thankful for the wood stoves in each cabin!

Our first morning, 6/7, began at Hunter Cove Wildlife Sanctuary, with lots of singing Blackburnian Warblers. A large flock of Red Crossbills flew over, two Yellow-bellied Flycatchers were heard clearly and then glimpsed, and a variety of common warblers were detected. A confiding pair of Canada Jays was the highlight – as they often are – but even the common warblers were tough to see today, so we focused on practicing our birding by ear skills.

Enjoying our delicious boxed lunches at the Rangeley Waterfront Park, with more Common Loons offshore, we delved into an impromptu gull workshop, using each age class of Ring-billed Gull as an introduction to molt, feather topography, and identification. A 3rd-cycle Herring Gull kindly dropped in for comparison as well. In inclement weather, we take advantage of whatever learning opportunities the birds are willing to provide!

After lunch, we poked around the Mingo Spring Birding Loop, with good looks at the likes of Least Flycatcher, Alder Flycatcher, and Dark-eyed Juncos among others. But as rain returned, we called it a day and settled in to dry out in front of our stoves instead of an afternoon of lake-watching from the BMC property.  And dinner was absolutely delicious!

Day 2 began with a brief walk around the BMC property (American Redstart, Ruby-throated Hummingbird, etc) followed by a foray over to the famous birding destination of Boy Scout Road, looking to build on the identification toolkit we worked on the previous day. We parked half the cars at one end and then walked the length of the road, birding along the way. But it was rather quiet here too – the ongoing story of June 2023. We did have some more Red Crossbills, a fantastic view -finally – of a Blackburnian Warbler, several Alder Flycatchers, and once again more Canada Jays. But this time, it was a family group of a pair with 2 juveniles in tow!

And then it began to rain. Again. A lot. But I give this group credit – they soldiered on! Of course the rain began in earnest when we were as far from either set of cars as possible, so there wasn’t really a choice, but still, spirits remained high and the birding continued. A pair of Hooded Mergansers, a singing Palm Warbler, and a Spotted Sandpiper were among the last birds of the outing, before the water had penetrated our clothing and it was time to call it a day and hope for better conditions next year!

  • Shorebirds Workshop, August 10.

The best way to learn shorebirds is to see them in their preferred habitats, feeding, moving, and mixing with other species, such as these Short-billed Dowitchers (a sandpiper) and Semipalmated Plovers here at Hill’s Beach in Biddeford.

An absolutely perfect day of summer weather (finally!) greeted us for this annual favorite outing. And the only thing better than the weather this day was the birding!  Recent insane rainfalls have led to very high water in many of our favored high-tide, upper-marsh locales, so we focused on tidal habitats including beaches and mudflats, altering our usual routine from the start.

Beginning in Biddeford Pool, we introduced shorebirds with several Spotted Sandpipers along Ocean Avenue before jumping into the mixed species flock on Biddeford Pool Beach on the outgoing tide. There we estimated over 1,250 Semipalmated Sandpipers and 200 Semipalmated Plovers as we learned the basics of shorebird (sandpiper vs. plover) identification and began to work our way up to teasing out a couple of White-rumped Sandpipers and Ruddy Turnstones from the masses. 2 Killdeer in flight overhead were our only two of the day.

Kicking off our shoes to spend the rest of the morning on the sandflats of Hill’s Beach, we compared a Piping Plover to the many (400+) Semipalmated Plovers and 30 Black-bellied Plovers. A single juvenile Least Sandpiper was out of place on the beach, but offered a perfect opportunity to closely study the differences in shape, size, and overall structure to the 150 or so Semipalmated Sandpipers that were scattered about. 59 Short-billed Dowitchers gave us the chance to really observe shape and feeding styles, practicing identifying these birds both near and far.

Over at The Pool, a distant “Western” Willet joined 7 “Eastern” Willets, as we advanced into subspecific identification just briefly before stopping for lunch as the tide began to roll in.

The afternoon was spent at Scarborough Marsh, where our first two stops offered little (other than a calling Greater Yellowlegs to at least practice our shorebirding by ear) due to the very high water in the salt pannes from the recent rains. Pine Point more than made up for it on the rapidly incoming tide, however, with one heck of a shorebird show: 1500-2000 Semipalmated Sandpipers, 400-500 Semipalmated Plovers, a few more Short-billed Dowitchers and White-rumped Sandpipers, better looks at “Eastern” Willets, and the icing on the cake: a cooperative Whimbrel – our 13th species of shorebird for the day.

Practicing with our identification tool kit, we tested ourselves on finding the uncommon species among the masses, and took a moment or three to simply sit back and enjoy the show. Now that we know how approachable shorebird identification really is, we can more fully appreciate these most marvelous migrants!

  • Monhegan Birding Workshop, September 23-25.

Northern Gannets and two Green-winged Teal flying with 6 Surf Scoters from the ferry and an adult Lesser Black-backed Gull greeting us upon our arrival seemed like a great sign for what would be a bird- and fun-filled weekend on the Migration Mecca of Monhegan.

Unfortunately, it turned out to be one of the slowest (for both species and diversity) fall weekends I have ever experienced on the island. That being said, a big list wasn’t our goal. It was to learn birds – their ID, their migration ecology, and everything else that makes the island so special for birds and birders. And this is not tour guide spin: a slower day is better for that as we had ample opportunity to view almost everything we encountered, study them, discuss them, and luckily, what the island failed to provide in quantity, it certainly delivered in quality of observations.

On each day, we would find pockets of warblers here and there, but we kept coming back to  one particular willow and a nearby thicket that constantly hosted 4-5 Cape May Warblers (photo above), 4 Yellow Warblers, a Yellow-bellied Sapsucker, and a smattering of others. The Cape Mays put on a clinic: all four plumages from pale, 1st-fall female, to bright and spiffy adult male were on display.

Over the first day and a half, we took what the island offered, besides exceedingly pleasant weather! There was the hen Green-winged Teal feeding within three feet of us, fly-over Rusty Blackbirds in the morning, and Great Cormorants on the cliffs on an afternoon short hike to name a few highlights. The skies were punctuated by the occasional migrant Peregrine Falcon and the constantly-hunting Merlins.

Granted, we were really just looking at birds to fill the time between the incredible meals at the Monhegan House!

On our final morning, a good migration overnight produced a new arrival of birds for the “morning flight;” the concepts and nuances thereof were topics of regular discussion.

The group’s high spirits earned them a great morning, with a taste of what Monhegan birding has to offer. There were American Pipits and Yellow-rumped Warblers in Morning Flight, a flock of 10 truant Bobolinks circling around, an immature male Belted Kingfisher displaying to a very-uninterested female, more Cape May Warblers, and a surprising fly-by Wilson’s Snipe.

At one point we had four juvenile Sharp-shinned Hawks dogfighting, exemplifying the difference in sizes of male vs female raptors. And the workshopping continued with Great and Double-crested Cormorants side-by-side, migrant raptors including several Northern Harriers, and more species before breakfast than we had most of the previous weekend! Speaking of breakfasts, goodness, they were good as well.

We finished up with a gull workshop on the shoreline, opening eyes to just how easy most gulls are most of the time. The advanced course was the fly-by 1st winter Lesser Black-backed Gull amongst Herring Gulls on the ferry ride back! And yes, we looked at butterflies, too!

The first of the 2024 Down East Adventures tours are already booking, with more to be announced soon. And since these Down East Tours fill up fast, don’t forget we offer a wide range of other tours, as well as private guiding services.

2017 Monhegan Fall Migration Weekend Tour Report.

IMG_6811-edited-edited
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.

Pine Warbler

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.

Peregrine Falcon

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.

Black-throated Green Warbler

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.”

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.

That chase and discussion of the vireo was exhausting!

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.

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…
