It’s been an extraordinary rarity season in Maine this fall. Perhaps it’s been the weather patterns, widespread drought, increasing use of neonicotinoid pesticides, or perhaps – according to a recent paper – geomagnetic storms!

But whatever it is, it’s made for an active month for vagrants here in Maine. Monhegan was epic at the end of September, October was pretty good on the mainland, and November has been exceptional. And, we still haven’t fully entered the rare-birds-at-feeders season, although there have already been quite a few noteworthy feeder visitors.

2025 Monhegan Fall Migration Weekend Tour Report

Personally, I’ve had a great fall, especially on Monhegan, and as you have read in my This Week’s Highlights blog (if you’re the one or two people who actually read it!), I’ve had quite a few notable finds, some fun chases, and overall great birding recently. But I hadn’t turned up a “mega” to add to the tally. On Monday, 11/24, I continued my search by taking a day to bird Peak’s Island, one of my favorite late fall birding destinations.

Arriving on the 7:45 ferry from Portland, I began my usual circuit, working around town to Picnic Point. The wrack line here always looks prime for a vagrant!

A short while later, at about 8:30am, I paused at one of my usual thickets on Seashore Ave, diagonally opposite the 5^th Regiment Museum. There are always birds here, augmented by a dense tangle, some tall trees, and a few small feeders behind it.

On Monday, it was very active as usual, with numerous Northern Cardinals, a lot of House Finches, and other typical residents. Movement caught my eye in a stand of still mostly-still-leafed willow trees towards the back right of the thicket, approximately 25 yards from the roadside.

Three warbler-like birds were chasing each other. One appeared to be an aggressor, and I was hearing repeated short, high-pitched call notes that were either, or very similar to, Nashville Warbler. It’s been an extraordinary fall for “late” Nashville Warblers (although they are likely drift vagrants, mirror vagrants, or even reverse migrants rather than just behind schedule), so this was not too surprising. But three non-Yellow-rumped Warblers in one tree? That’s notable on November 24^th!

The first bird I saw well was a bright, adult male-type Nashville Warbler (NAWA). The birds, still chasing each other and not sitting still, were not easy to see, but the second bird I got my binoculars on was rather confusing. I observed it for as long as I could, but the distance was just a bit too far.

A very drab Orange-crowned Warbler (OCWA) first came to mind, especially with the yellow undertail coverts, but the bird was really, really gray. A flat, cool, not at all yellowish or greenish gray. It was flicking its tail like a NAWA, but even more emphatically. It turned around, and I saw its breast, and there was a small amount of yellow there. Wait, what!? The patch was smaller and more isolated than a drab female Northern Parula, but there were no wingbars are at all, and it was too long-tailed.

I noted an eye-ring, but the distance made it hard to tell how bold it was, whether or not it was complete, or even if it was really white like a NAWA. I went for my camera, hoping to zoom in to see detail, but the birds were far too active and in too dense of a twiggy tree, so coupled with the distance, this was a complete fail.

Two birds departed to the right, but the bird of interest remained for another minute or three, calling very similarly to a Nashville Warbler, but quite emphatic. I then lost it, too.

By now, I was putting the pieces together and was under the suspicion that this was a Virginia’s Warbler, but I was not convinced. With all three birds departing as of 8:48, I opened up my Sibley app to refresh my memory (it’s been quite some time since I have seen a VIWA!) and listen to the call. The call recording on the app included two pitches of calls, the second of which was spot-on for what I was hearing from this very drab, gray, not-quite-Nashville warbler.

Hmm…but why didn’t I notice the yellow rump? Or was I just focusing on the rest of the bird? All of the views were so painfully brief, and I never saw the complete bird at one time.

About 10-15 minutes later, the trio returned: the adult male-type NAWA, a second, drab immature-female-type NAWA, and the likely VIWA. In a brief view, I noticed the all gray head, reminiscent of a female American Redstart, and confirmed the presence of yellow in the center of the breast.

The birds departed again, to the right, across Ryefield Street, but I only glimpsed one bird and it was likely the VIWA. I walked around the block, noticed a few feeders on New Island Avenue, but I did not find any warblers. Since they had returned to the original stand of willows three times now, I stood in place now, about a full hour after my original observation and I started sending out texts and scribbling notes.

I noticed that the recycling container at the house adjacent to the thicket had been taken in. Damn; I missed the homeowner! I needed to get closer to the thicket if the bird returns, but I am absolutely unwilling to trespass or enter yards without being invited/given permission. Many of you have understood this from my tours to Monhegan, but I stand by this elsewhere. But did it cost me today?

Happily, a short while later, the homeowner was in his yard and after a brief chat, allowed me to hang out in his backyard. It was now 10:28. He even brought me a comfy chair! I was so appreciative, now that I was camped out next to the willows, no warblers reappeared. I took another loop around the block, then returned to my chair. A single Evening Grosbeak dropped into the thicket, and I glimpsed what was almost certainly a Lark Sparrow within a House Sparrow flock, but I did not pursue it to confirm.

By 11:15, I was cold and needed to get a real walk in, so I departed, birding my usual circuit out to and through Battery Steele (found a Common Yellowthroat there) and otherwise enjoyed a rather birdy day on the island. A Hermit Thrush, a couple of Swamp Sparrows, a growing cadre of Red-necked Grebes offshore, and tons of Red-breasted Nuthatches in the woods. Song Sparrows were also unusually abundant.

I walked into town for lunch to go (the wraps at Unruly Girls’ Peaks Cafe are fantastic as always, but the hot chai was even more clutch!). I was back to the thicket at 1:36. The sun that broke through while I was far away had mostly been enveloped by clouds once, and the wind was picking up. Neither was particularly helpful. I departed at 2:25 to catch the 2:45 departure (I had planned on leaving before lunch!)

I was frustrated. I knew what I saw, but was bothered by what I did not see, and how unsatisfying and conclusive my views were. I felt confident that it was indeed a VIWA, but I don’t like birding by default or identification by the sum of all parts!

I thought about going back the next day but couldn’t. I must say, the oral surgery may have been less painful than having this bird get away!

I looked at guides, viewed photos online, and concluded there was little doubt that I had seen a VIWA. But the mind can play tricks on you, and memory can be affected by the post-observation studies, so it was bothering me. Jeannette asked if I was going to “count it?”

I didn’t know. So, on Wednesday morning, I decided to be a little late for work and go back to Peak’s Island. I couldn’t help it; I had to! Jeannette agreed.

Walking to the ferry terminal, I stumbled upon a Nashville Warbler on Commercial Street, near the cruise ship terminal, which I took as a good sign. 7:45 ferry, 8:05 arrival on the island, and I was to the thicket by 8:30, after a thorough check on Picnic Point on the way (the foggy conditions had me hoping to refind the bird on the wrack line like so many late-season insectivores find sustenance).

I stared at the thicket, but overall bird activity was much slower than two days prior. At 8:55, I began walking down Seashore, towards Maple Street. I soon heard warblers! I first heard a Yellow-rumped Warbler from quite some distance, but then heard NAWA, or NAWA-like, calls.

In the side yard of 66 Seashore, I found not three, but 5 warblers: 2 NAWA, a YRWA, and a drab Orange-crowned. Very drab. Hmm…could I have blown this mystery warbler? Was this all I had seen? No, no way! And then warbler #5 popped out: Virginia’s Warbler!!!!!

Between this yard, and the first yard on Maple Street a minute later, I had several perfect views at varying distances, and all field marks were observed. With a good look, there sure wasn’t any mistaking this bird!

I followed the flock back towards the original thicket and willow trees, but I lost their tail. I decided to be responsible and head back for the 10:00 ferry and get to work. I also had left my Tylenol in the car. Besides, my job here was done! This is the 4^th or 5^th record for Maine, and the first away from Monhegan.

Addendum: Several friends arrived on the next ferry, and after a short while found the bird in the same area, often returning to the original thicket from Monday. I was so focused on identification of the VIWA that I probably didn’t take a full inventory of all of the warblers that were around. They had at least 4 OCWA now, 2-3 NAWA, 2 YRWA, and crushing views of the VIWA. The bird was seen by many through the afternoon. And thanks again to the homeowners who accepted my presence in their yard and invited others in later that day!

I also can’t help but wonder if there will be a “Patagonia Picnic Table Effect” as birders descend upon and follow this possibly-growing flock of unseasonable warblers. Could I be heading back to Peak’s soon? I’ll at least be able to grab another Mediterranean wrap this time.

12/1 UPDATE: The VIWA has not been seen since the afternoon of 12/29. Birders searched for it on 12/30 and had 1+ NAWA and 4 OCWA in the area. Today, Jeannette and I spent the morning looking for it to no avail. In the Seashore Avenue area, we had 2 NAWA and 2-3 OCWA. As we widened our search, Jeannette and I had a continuing COMMON YELLOWTHROAT in the same spot as last Monday and another OCWA, both near Battery Steele.
