2026 Spring Monhegan Migration Weekend Tour Report

What’s better than a Blackburnian Warbler at eye level in an apple tree?
Such are the thrills of birding Monhegan in spring!

Another remarkable Monhegan Spring Migration Weekend is in the books. Every day out here is different in migration, and every tour is unique. But this one was particularly full of superlatives.

It seemed slow. Low numbers, low diversity, but yet with new birds being seen every day we ended up with a very good, above-average tally of 95 species, with the 18 species of warblers being just about the long-term average.

While numbers of individuals, especially warblers, were dreadfully low, we more than made up for it with quality. Quality of species, but especially quality of sightings. Just about everything was seen so well. A recurring theme of the weekend was definitely “wow, that was a great view!” or “what a fascinating behavior!”  The bird-watching was simply divine!

Northern Parula

Due to ferry schedules, we now begin the weekend with a casual birdwalk at the Marshall Point Lighthouse (and up the road) in Port Clyde. Friday morning was pleasantly birdy, with great views of American Redstarts, Black-throated Green Warblers, Yellow Warblers, and Northern Parula. We also picked up a few species we won’t see on the island – like House Finch and Turkey Vulture – and introduced our visitors from the west to the likes of Common Eider and Black Guillemots.

A pleasant boat ride (it sure beat last year!) was very productive, with 2 pairs of Atlantic Puffins seen very well on the water, an immature Great Cormorant, and most notable: 10 truant Purple Sandpipers on Shag Ledge.

We arrived at the island, soon greeted by a calling Sora. We expected that call would torment us for the next several days. After checking in and having lunch, we began our island birding. It was pretty slow overall, but we started having such great experiences.

Female Common Yellowthroat

The two Green Herons at the Ice Pond were unusually conspicuous and confiding (as they were all weekend). While talking about eiders and Black Guillemots, a spiffy drake Long-tailed Duck pops up right in front of us. Then, while scanning the Outer Duck Islands, a pair of American Oystercatchers fly through my field of view – my 232nd species on Monhegan, and only about the 7th or so Island Record!

Red Crossbills were one of the stars of the weekend, and we began our good fortune with observing them really well each day, starting with 2 females and 2 juveniles feeding next to the Ice Pond. And remember that Sora, starting its annual taunt? Well, it (or as it turns out, one of at least 2) was surprisingly close to the pumphouse when we arrived, so we used the time to wait patiently for the outside chance of an appearance.

And about 15-20 minute of tantalizingly close, incessant calling, there it was – a Sora! In the open! Foraging for about a minute in a narrow chunk of marsh grass, and then flying across a patch of open water. Everyone in the group saw a Sora!

Then, a text from a friend came through, and the continuing Lark Sparrow was in her yard. A private yard, but we were granted the privilege to access it, and when we did, the Lark Sparrow was nearly at our feet!

We learned the value of dandelions, too, as they are the first fresh seeds of the year.

Quality views of the notable birds on the island, our self-found rarity, Red Crossbills everywhere, and yeah – we saw a Sora!  Not bad for the first day, and we didn’t even arrive until 11:30am.

Wilson’s Warbler

On Saturday morning, we awoke to an ambiguous radar image overnight, but there wasn’t much overhead after dawn, other than a small migrant flock of Blue Jays. We took the time to learn a little about the radar, decipher that it was probably a lot of pollen in the air overnight rather than birds, and ground-truthed that with our copious sniffles.

Our pre-breakfast walk was also rather slow by Monhegan morning standards, but observations and species were slowly building. Once again, we continued to comment on the quality of the observations and bird experiences. There was the three-pair Yellow Warbler brawl that took place inches from us. Cedar Waxwing flocks eating apple blossoms, great views of colorful Magnolia Warblers and American Redstarts, a Merlin hunting robins and grackles (unsuccessfully), etc.

Although Yellow Warblers are one of the most abundant breeding birds on the island, and they were often all around us, we never tired of observing them, watching their behavior, and seeing what they were eating.
The “Octopus Apple”

After breakfast, we watched a displaying Sharp-shinned Hawk and then found another notable bird out here: an adult Broad-winged Hawk! It was circling low overhead to really show off for us, too. I don’t know if I have seen one out here in spring before. And we finished with a Rose-breasted Grosbeak and Indigo Bunting, always crowd-pleasers.

The mid-day break was anything but a break – at least for me, however. I had just finished crushing a couple of slices of Novelty pizza and was walking back to the Yew when a group of birders from Rhode Island flagged me down. “I think we just had a kite!” Jen Leito says. She showed me the photos, and sure enough – it was a Mississippi Kite! I grabbed my phone to get the word out, and at the same time, Mik Oyler was reaching for his – the Mississippi Kite was near the brewery. It then perched, and then he saw it flying off to the east.

I of course had turned around and was walking up Horn’s Hill and began to hawkwatch. It was time for me to meet the group though, so I started walking downhill. I had just about reached the Novelty once again when Paul Dorion and Kristen Lindquist texted that they had the bird from the top of the hill. I then sprinted up the hill (scope, boots, back-pack…and my Fitbit tracked it all, the spike offering a chuckle later!) and scanned again. Catching a quick glimpse of it through the treetops, it was the world’s least satisfactory view of such a Mega rarity. In fact, even though I saw it “well enough to count,” it was so underwhelming that I wondered if I would even bother putting it on my list!

I then jogged back to the Yew, met the group, and the search began. Focusing on the southern end of the island, we kept one eye on the sky, but no more reports of kites were to come. Instead, we enjoyed the occasional pockets of warbler activity, slowly adding new species to our trip list as we basked in more great views of Red Crossbills. But alas, the kite was gone. Or was it?

Somehow, I never thought of taking a photo when all 11 of us were together, but I am still happy to see people taking advantage of the flexibility of our tour itinerary to enjoy other aspects of the island…including rest!

On Sunday, the weather forecast had greatly improved, and we awoke to cool and cloudy conditions, but no precipitation would fall before dusk except for a few very light afternoon showers. An easterly wind overnight appeared to have shunted the overnight migration well inland, and it was once again a non-existent morning flight, and therefore another relatively slow morning.

But once again, great looks and notable birds: a continuing female Long-tailed Duck that we finally spotted, a Tennessee Warbler or two, and a very intriguing and thought-provoking study of the world’s dullest and somewhat-streaked female Pine Warbler for yet another rewarding teaching moment.

With a near-complete turnover in the group between Saturday and Sunday, we set out to “clean up the dirty birds.” Needless to say, we didn’t expect that to include more visuals of the Sora though! But once again, patiently waiting as a bird called (this time, on the other side of the marsh just off the road) was rewarded when not one, but two(!) Soras popped up from the grass, taking flight, fluttering a short distance, gangly legs dangling, before plummeting back into the meadow. Another Sora sighting!? Incredible!

The rest of the morning, and the afternoon, were exceedingly slow, but we enjoyed more Red Crossbill quality time, had some more instructive moments, and spotted an Arctic Tern off of Lobster Cove.

Indigo Bunting

There was fear of a wash-out on Monday, but after showers, mist, and drizzle overnight with periods of heavier rain, we awoke to only mist and drizzle as we stepped outside. Great views of two different Indigo Buntings highlighted the first walk, while after breakfast we enjoyed some time with a Blackburnian Warbler, before settling into a requested gull workshop. 3-4 age classes of both Herring and Great Black-backed Gulls were before us, so we began the lesson.

And then the skies opened up. A soaking downpour didn’t last long, but it was efficient. I give everyone credit for powering through, but during a lull in the rain, I finally called it quits at around 11:00am – still more birding time in the morning than we expected. In fact, by the time we got together again at 1:00pm, the rain had stopped and there were already peaks of sun!

Rain delay.

Bluebird skies returning.

As the skies cleared, we enjoyed a pair of Blackburnian Warblers and Red Crossbills yet again, heard a very uncommon for the island Prairie Warbler, and then heard the report of another rarity: a Yellow-throated Warbler! We weren’t far away, but the bird, found by Mackenzie McKnight along Pumphouse Road, had gone AWOL. We began to search but soon thereafter, Bill Thompson relocated it on Wharf Road, so we raced around the corner and were treated to delightful views – even some in the scope!

(Poorly phone-scoped photo)

What a great way to cap a wildly successful tour, but with time remaining, we tried to re-find the Lark Sparrow for the second half of the group (it was not seen since Saturday) but instead finished with a glorious Rose-breasted Grosbeak singing in the sun!

Six of ten til’ the end of Day 3.

As usual, Jeannette and I spent a day off together the next day, enjoying the birds, food, beer, and friends of Monhegan. The birding wasn’t too shabby either, thanks to a light flight overnight. We began with an Olive-sided Flycatcher at dawn behind the Yew (and 1-2 more later), more Tennessee Warblers (6+), an increase in Blackpoll Warblers, an arrival of Swainson’s Thrushes, and a few other species new for the weekend.

Southwest…rarity winds are a’blowin!
Traditional gratuitous food porn photo of the tour. This year’s entry: the coffee-crusted filet
at the Monhegan House.
2-3 Olive-sided Flycatchers arrived overnight.

It was a day off, so we dallied at breakfast (I must confess to having a second breakfast sandwich!) and enjoyed a little more coffee. Jeannette was photographing the Eastern Bluebird feeding around the lawn, as I stepped back out of the cabin at 9:40, but I looked up to see a raptor coming right for us. Low. Fast.

“WHAT’S THAT?! THE KITE! LOOK UP! RIGHT OVER YOUR HEAD!” And other indecipherable words and perhaps a few colorful ones, too. Incredibly, after a 2.5 day absence, it was back!

The bird proceeds to glide low over our heads and disappears behind the spruce line where we always start our day. Hustling over that way, we are near the “chat causeway” when the kite appears. We watched it for several minutes as it soared, and yes, kited, directly over our heads. Jeannette had to zoom out with her camera. I had never made eye contact with a kite before, but it clearly looked down, directly at me (literally and perhaps figuratively!), cocking its head to analyze. An absolutely crippling view. Yeah, this made up for my dissatisfying view from two days before, to say the least!

We got the word out, and Bill Thompson came jogging in from the other end of town, picking up birders as he went. We saw it over the Wyeth driveway, heading toward Lobster Cove. We were so happy many people had now seen it, too!

Interestingly a short time after our initial sighting, I spotted the adult Broad-winged Hawk, too. While that bird was gaining altitude and apparently departing, it could not be a coincidence. But where were these two raptors hiding for more than two days?

It turned out the kite would be seen all afternoon (and at least through the next two days, too!), by us, and many, many others, including four arriving bird tour groups. It was often kiting over Lighthouse Hill, catching some insects (bees?), and while attentions were often turning elsewhere, I could not stop myself from watching and enjoying it every time one of us saw it. Jess Bishop had arrived just in time, and as Jess, Bill, Jeannette, and I wandered town – often in the opposite direction of the masses – we always paused for kite watching.

Magnolia Warbler

What an incredible way to end the weekend! It’s always tough to leave Monhegan, and I expected more notable birds would arrive (they did), but the 1st island record of Mississippi Kite would be hard to top (it wasn’t), and my second fulfilling experience with it may never be surpassed. I am mad I didn’t get it on the official trip list and share its glory with my group though!

Interestingly, although the weekend was “slow” by May on Monhegan standards, and the numbers of individuals were low (except for Ring-necked Pheasants. My goodness, they have had a productive year!), the weekend’s tour birdlist added up surprisingly nicely! And unlike some tours, where fleeting glimpses seen by half the group were the norm, almost everyone saw almost everything on the list. Here’s the scoreboard.

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. In addition to the above, birds that I only saw on my own, before or after hours, or during breaks included:

  • MISSISSIPPI KITE, 5/23 (with m.obs…see above and below).
  • 1 GLOSSY IBIS, 5/23 (with Mik Oyler; flying past harbor at dusk)
  • 1 Wood Duck, 5/25.
  • 10 Greater Yellowlegs, 5/25 (with Bill Thompson)
  • 1 Alder Flycatcher, 5/25 (with Jeannette)
  • 1 Dark-eyed Junco, 5/25.

New species for the weekend seen with Jeannette included:

  • 2-3 Olive-sided Flycatchers
  • 6 Swainson’s Thrushes
  • 1 Spotted Sandpiper
  • 1 Willow Flycatcher
  • 1 White-crowned Sparrow
  • 3 White-winged Scoters
  • 1 Solitary Sandpiper (with Bill Thompson and Jess Bishop)

This made a very respectable weekend tally of 107 species!

Their “countability” might be in question, but their photogenic-ess never is!

This Week’s Highlights 5/22– 5/29/2026.

A Mississippi Kite was discovered by a group of visiting birders from Rhode Island on Monhegan on Saturday morning. Moments later, it was seen by two other parties, and then the chase was on. I did a wind-sprint up Horn’s Hill and managed to catch a most unsatisfactory view of it as it disappeared behind trees. Unfortunately, my tour group could not relocate it in the afternoon, and it was considered a 1.5 hour-wonder. Then, on Tuesday morning, right after breakfast, I stepped out of our Trailing Yew cabin and started yelling across the lawn to Jeannette, who was looking down, photographing an (uncommon on the island) Eastern Bluebird. It then proceeded to pass right over our heads, and a few minutes later, it was even lower and closer.
This was most definitely not an unsatisfactory view!

I spent 5 of the past 8 days on Monhegan, first with a tour from Friday the 22nd through Monday the 24th, and remaining with Jeannette through the next day. I’ll have a trip report, chock full of photos, by next week, but for now, here are some of my daily highlights. We had a total of 107 species, but only 18 species of warblers. But the rarities and the overall quality of observations and experiences, really did make up for it.

Bicknell’s Thrush Weekend

June 12-14, 2026

The latest incarnation of our Bicknell’s Thrush weekend offers more chances to see the enigmatic Bicknell’s Thrush and even better boreal birding opportunities!

With two full mornings in the area, we’ll have flexibility to offer two visits to the realm of the Bicknell’s. While Bicknell’s Thrush is the primary target, this enhanced itinerary will also give us an even better chance at other boreal species, including Canada Jay, Boreal Chickadee, Black-backed Woodpecker, Olive-sided and Yellow-bellied Flycatchers, Palm and Blackpoll Warblers, and especially Philadelphia Vireo and Mourning Warbler.  By staying in Colebrook, NH we have the opportunity to look for additional boreal targets anywhere from Vermont’s Northeast Kingdom (the famous hotspots are only 30 minutes from Colebrook!) to the Umbagog NWR area.

This Week’s Highlights, 5/23-5/30/2025

This Lark Sparrow – always a treat in spiffy spring plumage – was among the notable birds form a
stellar weekend on Monhegan.

Five days on Monhegan Friday the 23rd through Tuesday 5/27 yielded a total of 106 species, including 22 species of warblers. It was the best Memorial Day Weekend on the island in several years, and at times, it really felt like “the good ol’ days” with a flock of warblers in every tree. Back in the real world, I was mostly guiding for local breeding specialties, but did have a few observations of note. But mostly, of course, my highlights were from my time on the island.

  • 3 Blue-winged Teal, Weskeag Marsh, 5/23 (with Evan Obercian).

2024 Spring Monhegan Migration Weekend Tour Report

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.

Male White-winged Crossbills.

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.

Pink Lady’s Slipper in the woods.

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.

Juvenile White-winged Crossbill

…. 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.

This Week’s Highlights, 5/26 to 6/2, 2023

This first summer male Blue Grosbeak was present on Monhegan for at least a week, and unexpectedly, was flycatching for seaweed flies in shoreline rocks for most of the time, including the two days we looked at it with my Monhegan Spring Migration Weekend tour group.

With 5 days on Monhegan and one (half) day offshore, I enjoyed a lot of great birds this week. My observations of note over the past seven days included:

  • 1 Mourning Warbler, our property in Durham, 5/26 (Yard Bird #137!)
  • Monhegan Island with our Monhegan Spring Migration Weekend Tour group (full trip report and photos to come).

Daily:

  • Impressive numbers of Red Crossbills swirling around the island and tough to quantify, including many juveniles. High counts of largest flock(s) in the mid-20’s.  Three WHITE-WINGED CROSSBILLS were present each day at least through the end of the weekend. Rare for the island, a pair of HOUSE FINCHES appeared on the 27th and continued through the end of our stay.  Here are my group’s other daily highlights.

5/26:

  • 11 Bay-breasted Warblers (FOY)
  • 1 Cape May Warbler (FOY)
  • 1 female Evening Grosbeak
  • 1 Black-billed Cuckoo
  • 1 continuing ORCHARD ORIOLE
  • 1 Philadelphia Vireo (FOY)

5/27:

  • 1 continuing male DICKCISSEL
  • 1 continuing female/imm male SUMMER TANAGER
  • 1 female ORCHARD ORIOLE
  • 1 Olive-sided Flycatcher (FOY)

5/28:

  • 9 GLOSSY IBIS – circled the island early in the morning but did not land. My 225th Island Bird!
  • 1 probable immature male PURPLE MARTIN
  • 1 continuing 1st-year male BLUE GROSBEAK
  • 1 immature BROAD-WINGED HAWK
  • 1 continuing male DICKCISSEL

5/29:

  • 1 pair ORCHARD ORIOLES
  • 1 continuing SNOWY EGRET – Jeannette and I finally caught up with it for my 226th Island Bird!
  • 1 continuing 1st year male BLUE GROSBEAK
  • 5/30 (With Jeannette):
  • 1 continuing male ORCHARD ORIOLE
  • 1 Field Sparrow
  • Did not try to catch up with continuing rarities, although two quick checks did not turn up the Dickcissel or the Blue Grosbeak.
  • The Zeiss Pelagic with Cap’n Fish’s Cruises out of Boothbay Harbor, 6/2. This special mini-pelagic, sponsored by Zeiss Optics visited Eastern Egg Rock before heading 20 miles offshore. Trip report to come, but for now, the highlights:

1 Razorbill at Eastern Egg Rock

1 COMMON MURRE (between Eastern Egg Rock and Murray Hole)

350-400 total Wilson’s Storm-Petrels (FOY)

12 RED-NECKED PHALAROPES

  • TOURS AND EVENTS:

I’ll see you next week at the Rangely Birding Festival! Most (but not all) tours are sold out, but everyone can join me for the free and open to the public Birds on Tap! Event at Parkside and Main (beverages not included)!
