Blackpoll Warblers were pleasantly ubiquitous over the weekend, with endless opportunities to view them without neck strain for a change.

I just can’t walk away from a male Blackburnian Warbler in the sun, especially at eye-level. Just can’t do it. While Blackpolls were the most numerous migrant of the tour, as expected for the end of May, Blackburnian Warblers consistently stole the show.
Our 14th annual Monhegan Spring Migration Weekend was highlighted by three days of insanely gorgeous weather, 18 species of warblers, and loads of crossbills. But what set this year’s tour apart was how consistently amazing the looks were at so many birds, especially both crossbills and some of our favorite warblers.
The tone was set on our Friday crossing from New Harbor, with lovely weather and 2 fly-by Atlantic Puffins. And once again, we hit the ground running after our 10:15 arrival, taking nearly an hour just to walk up Dock Road. One of our favorite corners was just hoppin’, with our first stellar looks at both Red and White-winged Crossbills and Blackpoll Warblers, as well as our only Canada Warbler of the tour.

I ate a lot of hummus toasts for lunch at the Trailing Yew in an attempt to make up for copious breakfasts and decadent feeders.
The afternoon, and the next three days were filled with crippling view after crippling view. Blackpoll Warblers were everywhere, both males and females seen in close proximity repeatedly for good studies. American Redstarts were abundant, as were locally-breeding Common Yellowthroats and Yellow Warblers. But it’s been a long time since we have seen crossbills, especially White-winged, so well and so often everywhere around town and beyond. It’s hard not to name this species the bird of the tour this year.

In that first afternoon, some of our other highlights were a fleeting glimpse of a Black-billed Cuckoo, and later we found a female Purple Martin. Birds were just unusually low and cooperative, despite the gorgeous weather, so that really set this first day apart.

My days started even earlier than I would have liked as pheasants took to calling from the railing right outside my bedroom window. At 4am. 4am.
Unfortunately, the NEXRAD radar archive was down for the duration of our stay, so I can’t do my usual analysis here, but on Saturday morning, a light morning flight of mostly Blackpoll Warblers and American Redstarts suggested at least some birds had arrived on the light westerly wind overnight. There were also more Magnolia Warblers around, but overall, our two morning walks were slower than yesterday’s birding, but we would repeatedly find pockets of good activity with more great views of most of what we encountered.

This Cape May Warbler showed himself nicely, feeding on little midges/flies buzzing around the buds of this Red Spruce.
A Black-billed Cuckoo was as cooperative as they get, freezing on a bare branch for several minutes. Prolonged scope views of Red and White-winged Crossbills offered the chance to watch their amazing feeding behavior. The afternoon was a little slower, as expected, but still low and close Blackpoll Warblers and crossbills all around. Friends found a Blue Grosbeak that afternoon, which confirmed what I thought “had to be one” that flew across the marsh early in the morning but disappeared into brush before we could confirm its identity.




Of course we took some time to enjoy Rose-breasted Grosbeaks at Donna’s feeders, along with the omnipresent Ring-necked Pheasants.

Despite southerly winds overnight, Sunday morning was quite a bit slower, likely due to rainfall cutting off the flow of migrants from the south. We started the day with a bang though, as we moseyed down to the harbor to enjoy an up-close-and-personal Razorbill that ended up spending much of the day foraging in the harbor.
There was some passerine turnover overnight, however, and new birds this morning included an Alder Flycatcher, a calling Olive-sided Flycatcher, and finally a Tennessee Warbler – perhaps our first uncooperative warbler of the trip! The bird of the morning, however, was Blackburnian Warbler, as we started the day with amazing views just as we started and finished the morning with repeated great looks at males and females. Again, we were just in awe of the repeated great views we were getting of so many species, even if, yes, it was slow by Monhegan standards.


A nice selection of flycatchers over the weekend afforded the opportunity to learn how to break them down via primary projection, such as in this long-winged Eastern Wood-Pewee.
In the afternoon, we took the obligatory walk up to the lighthouse, both for some hawkwatching and snapshots. However, we ended up being enthralled (OK, I was enthralled) by a massive gull feeding frenzy that broke out over the lighthouse hill and beyond. It became clear that the gulls were not just enjoying the weather to soar on thermals but were feeding on some unseen flying insect. While a common event on the mainland, none of the birders present out here has ever seen anything like this over the island. The numerous Herring Gulls attracted a growing number of Laughing Gulls – the most I have ever seen out here (it’s usually just a few pairs around the harbor or fly-bys).

Monday, the last day of the tour, unfortunately, did not see us go out with a bang. With light easterlies overnight and developing clouds and fog, not only did a new wave of migrants not arrive, but it seemed like just about every single passage migrant had departed! Even Blackpolls were few and far between, and the number of American Redstarts seemed only on par with the number that remain out here to breed.

But once again, White-winged Crossbills stole the show, with the pre-breakfast walk highlighted by incredible views of a feeding family group. And although slow all day, we covered some ground and slowly built up our triplist with everything from a Purple Finch to a calling fly-over Black-bellied Plover. We studied a Great Cormorant (and later, a second), and finally caught up with the long-staying Green Heron in the ice pond. Three tarrying Black Scoters were a surprise in Deadman’s Cove, but not nearly as surprising as the drake Green-winged Teal loafing with Common Eiders on Neigh Duck!

After lunch, an unusual-for-here assortment of swallows over the marsh included two Bank, one Cliff, joining the 2 Tree Swallows and more Barn Swallows that have been out here all weekend. Seawatching at Lobster Cove produced a hen Long-tailed Duck right off the rocks that somehow disappeared in front of our eyes.

Black Guillemots were all around the island, including some close ones off of Lobster Cove that were close enough to see those vivid red feet.

“Lefty” the Red-winged Blackbird has returned for at least his third summer on territory in the marsh.

With the tour coming to an end at about 3:00pm as just about everyone readied to board the Hardy Boat, rain began to fall, bringing our tour to an official close. However, it wasn’t until dinnertime that a few downpours arrived, and so we squeezed out one more comfortable day of birding.
It was just Jeannette and me now, but “FOMO” was unwarranted. While a White-throated Sparrow outside of the Monhegan House after dinner was unexpected for the date, we didn’t add anything new to the trip list that evening, or the next morning. Rain, heavy at times overnight and a strong south wind with fog in the morning precluded any movement of birds, and our pre-breakfast walk was dreadfully slow. Passage migrants were few, just about 9 Blackpoll Warblers, 1 Canada Warbler, and 1 Northern Waterthrush, and it felt downright June-like with birdsong being almost exclusively breeding birds. We did have another look at uncommon Monhegan birds like the Blue-winged Teal, Green Heron, and Bank Swallow, but it wasn’t the hardest day to walk away from.

…. Which was good, as we were forced to depart earlier than planned due to the cancellation of the afternoon Hardy Boat. With a low pressure system moving along the stalled front that likely reduced our flow of migrants over the second half of the weekend was also building the seas. Our 10:15 trip, however, featured following seas that made for a reasonable ride, but the fog remained thick until New Harbor. We did have 4 Red-necked Phalaropes materialize out of the fog, however, with one remaining on the water just long enough for Jeannette to reach for and get her camera ready.
So, while Monday – and our usual day off together on Tuesday – was lackluster overall, it was really hard to beat the weather, birding, and learning opportunities that this year’s tour offered. Hopefully, everyone will now know how to identify Blackpoll Warblers at least! Oh, and my goodness the crossbills…
We tallied a respectable 93 species, including 18 species of warblers, over the four-day tour. Although below our long-term average, this was slightly above recent spring weekends. The following counts are simply guesstimations of the number of each species we encountered each day. Not the number of observations (eg every time we passed the same singing Yellow Warbler) or even a guess as to how many were on the island on a given day, but some crude attempt to quantify how many individuals of each species we think we saw each day. The ebbs and flows and daily changes are more interesting than the undoubtedly inaccurate numbers. For species such as the two crossbills that move around, back and forth, all over each day, it was impossible to really know how many there were. “A lot” should suffice.

The above birds follow the “guide plus one” rule, meaning both me and at least one client need to see the bird for it to go onto the list. I saw a Northern Mockingbird on three occasions, for example, but somehow never saw it during the tour! Likewise, an American Woodcock over the Island Inn after sunset on the 26th and the White-throated Sparrow that Jeannette and I heard after the tour ended on Monday, along with our Red-necked Phalaropes on our way home on Tuesday did not count for the official tour list.

We didn’t care how common Yellow Warblers are…they’re still always beautiful! As are the sunsets from the Trailing Yew.
