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.

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.”

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.

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…

2016 MonhegZen Spring Birding Weekend PLUS Birds on Tap – Monhegan!

As I do most Memorial Day weekends, I head to Monhegan Island with a tour group for my “MonhegZen Spring Birding Weekend.”  But this was not going to be “just” a weekend on this wonderful, joyful, and bird-filled place. This was going to be truly special – it was “Birds on Tap – Monhegan!

A small group arrived with me on Friday, and boy did we hit the ground running. The first bird we saw off the boat was a Purple Martin zipping overhead – a nice rarity to get things started. As if my usual Monhegan-stoked Rarity Fever wasn’t already in full effect, the next bird we saw was a wet Empid. And let the games begin! Of course, this one was a pretty straightforward Alder Flycatcher after we got good looks at it and heard it call.
ALFL

American Redstarts, Northern Parulas, and Blackpoll Warblers were common and conspicuous as it took us over an hour just to walk up Dock Road!  A great look at a male Bay-breasted Warbler near the Ice Pond was a treat, and we caught up with part of the small flocks of Red and White-winged Crossbills that have been wandering around the island. We saw at least 8 Red and at least 6 White-winged, including fresh juveniles of each – likely having bred out here in the late winter and early spring.

A Sora calling in the marsh didn’t really stop all weekend, and Yellow Warblers were particularly conspicuous around town.

And our FOY Novelty pizza.

While I – and the group – were hearing a little too much “you should have been here yesterday,” we were pretty content with the leftovers of the fallout, with 16 species of warblers by day’s end, including impressive numbers of Northern Parulas.
NOPA

A rare-in-spring Dickcissel flew over the Trailing Yew as we awaited coffee, soon followed by a close-passing Yellow-billed Cuckoo. After a strong flight overnight, there were a lot of new birds around. Fueled by the delicious Birds & Beans coffee being brewed by the Trailing Yew all weekend, we began our birding, soon picking up lots of new arrivals including Cape May Warbler and Swainson’s Thrush.

Apple trees in full bloom all around town were one of the major draws for birds and birders. In fact, you could basically pick an apple tree and sit in front of it long enough to see at least one of all of the common migrants that were about, such as Magnolias Warbler…

Jeannette met up with the rest of the tour group arriving on the first boat from New Harbor, and caught up with us after catching up with two of the most cooperative Philadelphia Vireos you’ll ever meet that we all enjoyed along Dock Road.
PHVI

In town, we heard a White-eyed Vireo, another rarity (although one of the expected ones out here), ran into a few more of both species of crossbills behind the Ice Pond, and spotted the young Humpback Whale that has been making regular appearances close to shore off the island’s western shore!  And this Scarlet Tanager…which seemed an appropriate find since we have been consuming the coffee named for it!
SCTA

After hearing a singing Mourning Warbler earlier in the day for our 20th species of warbler on the trip, we had a handful of glimpses of a skulking female near the Yew. I turned around to follow a flitting Yellow-bellied Flycatcher. Training my bins on the flycatcher, I first focused on the branch behind it, which turned out to be hosting a roosting Common Nighthawk!

83 species of birds on the day, including 19 species of warblers made for one helluva day, but the fun was just beginning! In addition to my annual tour, this was the weekend of Birds On Tap – Monhegan!

A collaboration between our Freeport Wild Bird Supply, Trailing Yew, Birds & Beans, and Monhegan Brewing, we took our “Birds on Tap” series of events offshore to celebrate birds, migration, bird conservation (especially through consumer choices like what coffee to drink), and, yes, beer!

And one of the truly special events was a limited, 31-gallon batch of a special coffee-infused milk stout from Monhegan Brewing, featuring a pound and a half of the dark roast Scarlet Tanager coffee from Birds & Beans!
MARY POUR

I had the honor of announcing the official release, taking some of the first sips of this delicious light-bodied stout featuring a subtle sweetness from lactose perfectly balanced with a bitter roastiness from the coffee.

ON PORCH

Of course, we were also still birding. I promise!
GROUP AT BREWERY

In fact, we momentarily cleared out the brewery when a possible Orange-crowned Warbler (one was seen by others over the past two days) was spotted nearby. Rushing over, we carefully studied the bird before reaching the conclusion that it was indeed a pale Tennessee Warbler.
TEWA

After an unfortunate but necessary cancellation from our original speaker, Dr. Steve Kress arrived to save us – admittedly a feat marginally less heroic than what he did for puffins and endangered seabirds all over the world!

 

Giving the weekend’s keynote presentation on his work to bring Atlantic Puffins back to nearby Eastern Egg Rock, Steve explained the challenges he and the puffins faced before finally realizing his novel approach finally bore fruit, or should I say, pufflings.

Overnight, a back door cold front sagged southward, shifting the winds to an easterly direction and limiting the arrival of new migrants to the island. Our “Morning Flight Watch” with plentiful free Birds & Beans coffee for all at the Trailing Yew wasn’t too eventful, but things definitely picked up for the post-breakfast walk.

 

Jeannette led my tour group, and the birding was still a bit slow, relatively speaking. But, they finally made their way down to the pump house to see Eastern Kingbirds flycatching in the marsh. And, up to the lighthouse for the first time which was highlighted by a fantastic view of a female Blackburnian Warbler.
BLBW female

Meanwhile, Kristen Lindquist assisted me in leading the free, open-to-all birdwalk as part of the weekend’s special events. A nice mix of birders, residents, and visitors enjoyed a casual stroll. We chatted as we went, covering a variety of topics from bird migration to conservation to coffee to the ill-conceived industrial wind development scheme for the island’s southern waters.

 

Some folks, new to birding, may have left with the impression that Red-eyed Vireos were about the most common bird in the world, as quite a few were calmly and methodically foraging through apple trees in and around town.
revi

But perhaps this male Blackburnian Warbler would end up being a “spark” bird for someone! Because male Blackburnian Warbler!
BLBW male

With a light easterly wind continuing, and our group back together after more Novelty pizza, we walked up to Burnt Head, where we enjoyed some nice close passes from Northern Gannets
NOGA

Jeannette and I spent an extra night on the island, knowing we would need a little time to unwind after the even-more-chaotic-than-expected weekend of events. After a great dinner with friends, we listened to two Soras calling from the marsh and an American Woodcock still displaying somewhere overhead before turning in.

We awoke on Monday to dense fog and no visible migration on the radar, but the birding was actually quite good. We found a Nelson’s Sparrow in the Lobster Cove marsh, but also enjoyed how the damp weather (mist, drizzle, and a few showers) were keeping activity low and close, easily viewed in the blooming apple trees around town once again.
As a warm front passed through, with only a little more drizzle but rapidly warming temperatures and clearing skies, we took a post-pizza hike, heading deeper into the woods, which netted more of the island’s breeding species, such as many more Black-throated Green Warblers.
BTNW

Somehow – now how did this happen? – our hike ended at the brewery, where another pour of the Birds & Beans-infused beer was in order.
CLOSE UP POUR

Unfortunately, especially since the sun was now shining brightly, it was indeed time for us to head back to the real world, so Jeannette and I begrudgingly plodded down to the dock and boarded the Hardy Boat for the return.  It’s never easy saying goodbye to the island – its birds and our friends there – but today was especially challenging as we know a fight about the future of the island – including many of the migratory birds that pass over and through here – is looming.
