The 2017 Maine Bird Predictions Blog

24-l1050633_attw_male1nesowadnahunkrd-7-19-16_edited-1

Yup, it’s that time of year again. Not just time to celebrate the end of 2016 (is anyone really upset to see this year end?) and ring in the new, but reset the ol’ Year List (if you keep such a thing) and look forward to the avian wonders of 2017.

That means it’s time for my annual Predictions Blog, where I view into my crystal binoculars and attempt to forecast some of the “new” birds to grace the State of Maine, and my own personal state list, in the coming year.

But first, let us check in with my 2016 Predictions post, and see how I did.

Two birds were added to the cumulative Maine list in 2016. Incredibly, both were on Seal Island! A Great Knot on July 23rd followed an Ancient Murrelet in May that was later seen (presumably the same bird) at Petit Manan Island and then Machias Seal Island. While Ancient Murrelet was on my radar, and was part of my lengthy honorable mention list, Great Knot most definitely was not! In fact, this was one of the most amazing vagrant records in the state in some time.

My predictions for the next 25 species to be found in the state therefore has not changed too much. The new list is now:

1) Neotropical Cormorant
2) Graylag Goose
3) California Gull
4) Roseate Spoonbill
5) Spotted Towhee
6) Hammond’s Flycatcher
7) Bermuda Petrel
8) Black-chinned Hummingbird
9) Common Shelduck – with a recent spate of records in Eastern Canada, including three birds in New Brunswick in December,a pattern of vagrancy is definitely emerging. Provenance will always be a question however, as this species is kept in captivity. However, we used to dismiss every Barnacle Goose – for example – as simply an “escapee,” but its clear many are of natural vagrancy. Increases in the species in Iceland are a good sign that some of these recent records are of wild birds.
10) Fieldfare
11) Audubon’s Shearwater – on “hypothetical” list, but I think the record is good.
12) Little Stint
13) Anna’s Hummingbird
14) “Western” Flycatcher (Pacific-slope/Cordilleran)
15) Vermillion Flycatcher
16) Common Ground-Dove
17) Allen’s Hummingbird
18) Redwing – one in New Hampshire in March was a “near-miss!”
19) Western Wood-Pewee
20) Spotted Redshank
21) Zone-tailed Hawk
22) Gray Flycatcher
23) Ross’s Gull
24) Black-tailed Gull
25) Common Scoter

Meanwhile, I was very pleased to add six species to my own Maine list this fall. First up was the Black-throated Sparrow in Winter Harbor, which I visited on January 17th. Because it was discovered before I posted my Predictions Blog last year, I can’t count that as a prediction! But you can be sure I was happy to put this stunning southwestern sparrow on my state list anyway.
l1040396_btsp1winter_harbor1-17-15_edited-1

My only self-found addition was my 6th ranked species: Western Grebe. I found one at Simpson’s Point in Brunswick on April 17th. It’s always much, much sweeter to find, rather than chase, a new state bird!

Adding American Three-toed Woodpecker to my list was just a matter of finding the time and putting in the effort. In Mid-July, Evan Obercian and I used it as an excuse to spend a weekend around Baxter State Park, which eventually yielded a pair of American Three-toed Woodpeckers along Telos Road.

A long-staying King Rail near Moody Point in the Webhannet Marsh was my 4th addition of the year. It was very high on my honorable mention list, but I left it off the ranking this year.

My Washington County Tour in August once again produced a Sabine’s Gull, and once again it was in Canadian waters, despite our best efforts to follow it across the border. Therefore, I was elated when one was discovered at Sabattus Pond on October 29th. This was my only “drop what I was doing and rush out the door” twitch of the year. It was worth it. I really like Sabine’s Gulls.

And certainly last but not least was the Bullock’s Oriole in Camden that Luke Seitz and I drove up to see on November 25th. Another bird high on my Honorable Mention list, but it too was not on the official Top 25.

Great Skuas were again seen with regularity off of Bar Harbor, but I missed them on my paltry few trips offshore again this year. The nemesis continues! There was also a one-afternoon wonder Harris’s Sparrow in Belgrade in November.

But with my #1, #6, and #13 “next species” checked off, my updated list for my own next 25 species in Maine now reads:

1) Great Skua
2) Eurasian Collared-Dove
3) Graylag Goose
4) Say’s Phoebe
5) American White Pelican
6) Neotropic Cormorant
7) Fork-tailed Flycatcher
8) Tundra Swan
9) California Gull
10) Franklin’s Gull
11) Black-bellied Whistling-Duck
12) Slaty-backed Gull
13) Yellow Rail
14) Boreal Owl
15) Calliope Hummingbird
16) Cerulean Warbler
17) White Ibis
18) Gull-billed Tern
19) Hammond’s Flycatcher
20) Loggerhead Shrike
21) Ivory Gull
22) Roseate Spoonbill
23) Spotted Towhee
24) Virginia’s Warbler
25) Common Shelduck

GYRFALCON in Wells (January 2015)!

2 Replies

Gyrfalcons are one of those enigmatic birds of the high northern latitudes that are always a favorite among northern birders, and lusted over by those further south. I’ve been lucky enough to see quite a few in Alaska, one in Michigan, and even one in South Boston. And few sightings of mine will ever surpass the eyrie of three white morph juveniles that we saw in Kamchatka.

But I had yet to see one in Maine. Or, at least, seen one for certain: there was this large, dark falcon with shallow wingbeats that screamed by during a snow squall while birding at Fort Halifax in Winslow one winter morning with a friend. It probably was, but…

On January 13th, a dark morph Gyrfalcon was found ravaging a Herring Gull on a ballfield in Kennebunk by Shiloh Shulte. His crippling photos of this beautiful bird can be seen here.

We were in Georgia.

Meanwhile, the plot thickened. Shiloh’s photos were strongly suggestive of the dark morph Gyrfalcon seen in Madbury, New Hampshire on December 15th, with at least one more sighting later at the Rochester Waste Water Treatment Plant. Meanwhile, it came to light the bird was actually photographed in Maine on January 10th, in the Ogunquit River Marsh from Ocean Street in Ogunquit.

Then, yesterday (Saturday, 1/17), Bob and Sandi Duchesne, et al, refound the bird in the Webhannet Marsh, just north of Wells Harbor (via Harbor Road). Quite a few birders were able to make it down to the marsh, and observe the bird in the area through sundown.

Not surprisingly, a lot of birders converged on Wells Harbor this morning. Myself included.

I arrived at Harbor Road at about 8:00am, and a short while later, chatted with folks at the end of the road, at the marina and boat launch of the harbor. No sign of the “Gyr.” Several us decided to split up and search elsewhere, keeping in touch of course.

I walked Community Park, scanning the marsh along the way (9 Horned Larks, 2 Yellow-rumped Warblers). I then went up to Parson’s Beach, where there was a possible sighting a few days ago. No luck, but I was surprised to find a small flock of 6 Savannah Sparrows at the end of the road; unseasonable.

Next up, I drove Drake’s Island Road. A car was pulled over, and seeing that they were looking at a Rough-legged Hawk (also seen earlier by others from Harbor Road), I too pulled over. I watched the hawk for several minutes, before it took off rather abruptly. I thought I saw something streaking low across the marsh, but blocked by trees, I really assumed it was a figment of my imagination. Driving ahead to a better view of the marsh, I scanned to the south, spotting a dark lump in the middle of the marsh – a lump that I had not noticed before. Four Common Redpolls flew over. The lump moved. I scoped Harbor Rd and did not see any birders. It was dark, it seemed small-headed, and it was fairly big. But there was heat shimmer, and it was far, very far.

I called Noah Gibb, wondering where he was, and mentioning I spotted a “promising lump” to the north of Harbor Rd and I was racing over. As I pulled into the parking lot at the end of Harbor Road, at least a half dozen birders were now present, but looking in different directions, and clearly not excited. “Damn it,” I thought. Was my lump just a bona fide lump? My excitement waned.

But I set up the scope anyway, pointed it towards said lump, and turned to the other birders and said, “Do you guys know the Gyrfalcon is sitting out here?” After they all saw it, we enjoyed a good chuckle, but most importantly, we all knew where the bird was, and dozens of birders converged.

Between 9:55 and 10:50, many of us enjoyed this magnificent bird, which, through a scope, afforded more than satisfactory views. During the time, it made two sorties, one low over the marsh, taking a run at an American Crow, and another higher flight over the water, flushing up roosting gulls.

This is one beastly bird, almost certainly a female based on its size. Gyr’s don’t have narrow wings like a lot of falcons, but big, broad (especially at the base) wings that seem to fight tapering to a point. In many angles, they even suggest buteos or goshawks. The flight of a Gyr is incredibly fast and seemingly effortless. Its shallow wingbeats generate a lot of power. It’s really like a Peregrine Falcon on steroids.

After each flight, the bird returned to a piece of driftwood in the marsh, north-northwest of the end of the parking lot at the end of Harbor Road (Wells Harbor), about 1/3rd the way between here and Drake’s Island Road. From the boat launch on the north side of the parking lot, looking out at about 11:00, somewhat in line with a marsh-edge house along the western end of Drake’s Island Road.

This phone-scoped photo was the best that I could muster:

And this was the best flight shot I got of the bird in flight with my Nikon:

On a couple of occasions, the bird took off to the west, and we all lost site of it behind trees and buildings. It crossed the road once, heading over the salt pannes near the beginning of Harbor Road, and disappearing to the south. Several of us failed to locate it in the marsh to the south, and eventually, Luke Seitz and I gave into the call of second breakfast at Congdon’s Donuts.

When we returned to Harbor Road at 12:25, the Gyrfalcon was once again on her low driftwood perch to the north. At least today, the bird seemed to come back to this spot reliably, and it was observed there on and off through a little before 3:00pm. In other words, for birders seeking the bird, spending time patiently looking north from the end of Harbor Road (also, the parking lot at the end Atlantic Road in Wells Beach, accessed from Mile Road off of Rte 1) would likely be a good idea – and keep an eye out for promising lumps! And clearly, the bird covers some ground, so if it is not being seen, spreading out would be useful eventually. Hopefully, my description of the day’s sightings (and lack there of) offers some help in directing the next search, if necessary.

This was my 366th species in Maine, and Gyrfalcon was #5 on my personal “next birds” for my state list, as I wrote about earlier this month. But it was a Gyr, and Gyrs are awesome, no matter what list they are or are not on.

Several dozen birders came and went today, and not surprisingly, with so many birders in an area, and with so many people spread out and looking for the bird, there was a classic “Patagonia Picnic Table Effect” underway: when birders seeking one rare bird start finding others nearby. In addition to the Rough-legged Hawk (not many have been around this winter so far) seen on all three days, 2-3 Yellow-rumped Warblers at Community Park, and scattered Horned Larks, some of the other birds in the area that were reported included:

(Updated, 11:00am, 1/21)

1/18:
– 1 Eastern Meadowlark on Furbish Road in Wells (presumably the same bird that Kristen Lindquist and I found there on the York County CBC in December and has been seen at least once since).
– 6 Savannah Sparrows, Parson’s Beach.
– 2 Bohemian Waxwings, Wells Library.
– 1 Northern Flicker, Drake’s Island Road.
– 1 Snowy Owl, Drake’s Island Beach.

1/19:
– 1 Swamp Sparrow, Eldridge Road.
– 1 Merlin, Wells Harbor.
– 2 Dunlin with 128 Sanderlings, Ogunquit Beach.

1/20:
– Snowy Owl, over Wells Beach.
– 128 Sanderling, Ogunquit Beach.

Meanwhile, the overwintering drake King Eider at The Cliff House in York had quite a bit of visitation during these few days.

While dozens, if not hundreds, of birders from throughout New England were looking for the bird in the afternoon on the 19th and all day on the 20th, the Gyr apparently moved on. Late in the afternoon on the 20th, it was reported back in New Hampshire, in the marshes of Hampton – not far from where it was first spotted last month! Will the bird stick around there? Will it be back in Wells? Who knows, but hopefully, people will continue to enjoy the bird, and when its not being seen, spread out and look throughout all of the marshes of both states. Gyrfalcons travel widely in search of food, and there’s no reason why the entire area from Hampton through Kennebunk can’t be part of this bird’s winter range.

In the meantime, please enjoy Luke Seitz’s photos of the Gyrfalcon from Harbor Road on the evening of Saturday, January 17th (note especially the bird’s massive size and girth, and broad wings in relation to a Red-tailed Hawk that it took a run at).

2015 Maine State List Predictions

2 Replies

It’s that time of the year again! Time for me to look into my birding crystal ball, and make random guesses…err, insightful, educated, prognostications about what the next year will bring to Maine and birders’ state lists.

But first, let’s, as usual, review the previous year. For the full list of 2014 species predictions, you can visit my blog from last January here.

Two species were added to Maine’s all-time list in 2014, a Brewer’s Sparrow on Monhegan in May, and a Crested Caracara in Unity (and later in Norridgewock) in August. While both species were on my “long list” for future additions, neither made the top 25. Following the report in the spring of 2014 of a Crested Caracara in New Brunswick (the 2013 caracara in Nova Scotia – and NJ – was apparently not a fluke…albeit distinctly possible to have been the same individual), there’s little doubt Crested Caracara would have made it onto the list this year. But I don’t update the list as the year progresses, so alas, no credit for me.

Meanwhile, perhaps even more remarkable, was the Tufted Puffin seen sporadically off of Machias Seal Island in June and July. Without getting into geopolitical boundary disputes, I believe both Maine (waters to south and east of island at least) and New Brunswick (definitely when it was on land) can claim this bird. While the puffin was not technically new for Maine, it was the first record – and unequivocal record – since a somewhat-disputed record claimed by Audubon in 1834.

Next, I would like to call attention to #23 – Bermuda Petrel, an annual species that is on my list, but this is the lowest it has appeared. However, it very already occurred in Maine. Geolocator (“data-loggers”)data from researchers puts the birds well into the Gulf of Maine, and even within the margin of error, perhaps several birds have appeared within the usual boundaries association with state bird lists (it is well beyond the 3 mile political zone).

“Conservation and At-Sea Range of Bermuda Petrel” by Jeremy Madeiros, Bob Flood, and Kirk Zufelt in the June-July 2014 issue of North American Birds (V.67, no. 4) includes a map (p.555) of hundreds of locations from around the Atlantic Basin, including about a half-dozen within the Gulf of Maine.

(Members of the American Birding Association can read the article in its entirety here)

Whether or not we “believe” geolocators are accurate enough to document an occurrence is a discussion for another time, but I predict a bird will be seen or confidently tracked into nearby waters in the future. Therefore, that species has moved up the list. Neotropic Cormorant’s continued increase to the north and east, with increasing frequency of vagrants, bumps that species up quite a bit as well. I shuffled things around near the end as well, including replacing Yellow-legged Gull with Black-tailed Godwit

Otherwise, I have made few changes to my list of the next 25 species to appear in Maine:
1) California Gull
2) Graylag Goose
3) Neotropic Cormorant
4) Roseate Spoonbill
5) Ross’s Gull
6) Fieldfare
7) Hammond’s Flycatcher
8) Bermuda Petrel
9) Black-chinned Hummingbird
10) Spotted Towhee
11) Audubon’s Shearwater (on “hypothetical” list, but I think the record is a good one)
12) Little Stint
13) Anna’s Hummingbird
14) Redwing
15) Barolo Shearwater
16) Allen’s Hummingbird
17) Black-tailed Gull
18) Common Ground-Dove
19) Western Wood-Pewee
20) Spotted Redshank
21) Gray Flycatcher
22) Black-tailed Godwit
23) Brown-chested Martin
24) Long-billed Murrelet
25) Common Scoter

Personally, I added two species to my own “State List” this year, the Brewer’s Sparrow (not on my predictions list) during my MonhegZen Spring Migration Weekend:

And, on the MonhegZen Fall Migration Weekend, I finally added Yellow-headed Blackbird to my state list (after moving it out if the top 10 for the first year, dropping it all the way down to #24 for some reason – probably out of frustration about still not having seen one…it worked!)

(And yes, this is why birders go to Monhegan Island!)

Once again, I didn’t make it up north to look for American Three-toed Woodpeckers (#2), which were again reliable near Baxter State Park, and despite Great Skua (#3) being seen regularly off of Bar Harbor this summer, I only made it offshore on a whale watch there once in October – on a skua-free day. I did not see the reported Western Grebe (#9) off of Harpswell last week, and I missed the Crested Caracara three times! I also did not chase a Tundra Swan (#12) in Winterport in October, or a Virginia’s Warbler (long list) on Monhegan. I also did not see a Cerulean Warbler (long list) that was on Monhegan this fall as well.

So, without any further ado, here are my predictions for the next 25 species to be added to my personal list here in Maine (with quite a bit of reshuffling this year):
1) American Three-toed Woodpecker
2) Great Skua
3) Eurasian Collared-Dove
4) Slaty-backed Gull
5) Gyrfalcon
6) Graylag Goose
7) Say’s Phoebe
8) Western Grebe
9) American White Pelican
10) Boreal Owl
11) Fork-tailed Flycatcher
12) Tundra Swan
13) Yellow Rail
14) Sabine’s Gull
15) Franklin’s Gull
16) Black-bellied Whistling-Duck
17) California Gull
18) Ivory Gull
19) Calliope Hummingbird
20) Cerulean Warbler
21) White Ibis
22) Gull-billed Tern
23) Hammond’s Flycatcher
24) Loggerhead Shrike
25) Neotropic Cormorant

So there it is, the annual list. Now, it’s time to go birding!

Fork-tailed Flycatcher in Connecticut!

5 Replies

“I don’t always chase birds, but when I do…”

…And I almost never chase birds away from Maine, and I rarely even chase birds more than an hour away from home. Therefore, it was exceedingly out of character for me to even consider chasing the Fork-tailed Flycatcher that has been present in Lyme, Connecticut.

A vagrant from South America, most Fork-tailed Flycatchers that show up in late spring or fall are notorious “one day wonders:” found one day, and gone the next. That is why I have missed several, including a handful in Maine. In fact, one showed up 15 minutes away in Brunswick the day we left for Russia two years ago. Figures. I even chased one with friends on Stratton Island that involved a boat charter, a borrowed dingy, a rope, and a signpost as a paddle. We missed that one by about an hour.

In other words, this bird was a bona-fide nemesis, so one hanging out for 9 days as of Sunday was tempting my self-restraint. Then, as my friend Phil and I and were planning a birding day, we decided to go for it. Why not? We didn’t have a better idea, it would be a fun drive of listening to music and conversing, and we’d have the Patriots game to pass the time on the trek back. So off we went.

The drive seemed like it took forever! We were anxious – seeing reports that the bird had been seen first thing that morning only made us more excited – and it was a long, often-boring drive. Once the sun got high enough, we counted roadside Red-tailed Hawks to pass the time (17 starting at the 95/495 junction in Massachusetts).

We arrived at the Hadlyme Ferry slip parking lot at 10:40am, with about a half-dozen other birders still present. We were informed that it was seen as of about 25 minutes ago.

Although it usually only disappears for about 20-30 minutes at a time (to feed behind a nearby inaccessible hillside), it wasn’t until 11:20 that it reappeared – an agonizing, and bone-chilling (30F, light northwest wind off the river) forty minutes! The bird was well seen by all going about its business through 11:35.

The flycatcher was surprisingly inconspicuous as it fed on Pokeweed berries on the hillside.

It was far more obvious when it came out to attempt to flycatcher (we did see it go after a couple of small bugs, despite the cold temperatures).

But Phil and I were not yet satisfied – we didn’t come all this way for 15 minutes – so we waited for its return. This time, the wait was merely 15 minutes, and we then had a most-satisfactory and fulfilling time with the bird for about 40 minutes. Quality time with a stunning lifer! And more time for photographs and studying. The birds’ behavior – so far out of place at such an amazing season certainly piqued my interest to see what it was eating to survive.

It was already lunchtime, and Phil and I were definitely getting hungry. Furthermore, I did want to get over to Hammonasset Beach State Park for some fruitful birding to work on my Connecticut state list – a list lacking quite a few common birds, especially winter waterbirds. But it was hard to leave a bird as sexy as a Fork-tailed Flycatcher! “Let’s walk away from this Fork-tailed Flycatcher so I can look for Common Goldeneyes” said no one, ever.

The ferry slip area was quite birdy, with a little flock of Dark-eyed Juncos and White-throated Sparrows that also included a Hermit Thrush. A flock of 8 Common Mergansers were heading south down the river, while a migrant Northern Harrier passed overhead just as we were leaving. But I wanted more than one state bird on the trip, so after spending way too much time trying to find a place to eat: “closed at 1” does not mean “breakfast all day!” were among the examples of our lunch attempts being foiled.

We needed to start to make some progress eastward, and daylight is limited this time of year, so we skipped Hammonasset, and looked for lunch on a way to a park that looked promising on a map that was more or less on our way home. We finally had lunch – despite rather slow service that resulted in our birding time rapidly ticking away – and then rolled into Bluff Point State Park in Groton. There were two impounded back-bays, next to an airport, just a mile or two from the coast. On a map, that looked like a perfect spot to find some ducks…and Snowy Owls.

Unfortunately, we soon learned that we had to walk to the coast, and we didn’t have time to do that. A scan of the airstrip didn’t yield any owls, but the water – that looked good on the map – was nearly devoid of waterbirds! 8 Mute Swans, 7 Red-breasted Mergansers, and 2 American Black Ducks were it – and none of those were state birds.

I was disappointed, but really, I saw a Fork-tailed Flycatcher! The disappointment of only seeing one state bird on the day did not last long…and was completely forgotten as Phil and I cheered on the Patriots during their remarkable and exciting comeback that certainly helped make the drive home feel a lot shorter. As did -of course – the fact that we were successful in our twitch of one of the more charismatic vagrants that shows up in North America. I’d call the day a success, to say the least!

A Day Along the New Hampshire Seacoast

Leave a reply

It was like birding in another world yesterday as Kristen Lindquist and I headed south of the border…to the New Hampshire Seacoast. For one, we saw birders everywhere! Well, everywhere where there wasn’t wall-to-wall development. And goodness, even in winter, there are a lot of people around here (relatively speaking of course). Yup, we weren’t in Maine anymore!

But I have a lifetime listing goal of seeing 200 species in every state, and my goal was to hit that mark in New Hampshire by the end of this year. This goal is not for any “total ticks” target, or submission to any listing competitions, or anything else other than an excuse and occasional extra motivation to see more parts of the country. The 200 number seems a reasonable goal to me for most states (I won’t reach it in Hawai’i!) that involves seeing a fair sample of what a state has to offer, and usually in multiple seasons – whether its scenery, food, or other interests (i.e. Rutgers football bowl games!), there’s always a good reason to travel near and far and lots of fun to be had in the process. And of course I will be birding in between anyway, so long ago I began keeping track of it.

So the 200 goal was born, and it was time to get to know my neighboring state a little better. Outside of the White Mountains (where I love to bird, hike, and of course, guide), I really didn’t know New Hampshire birding and birding sites very well, and I am happy to say that has changed this year. While I joked with friends about “never having to bird in NH again!” after the goal was met, I did learn quite a bit about birding the state in the process. But yeah, I am partial to birding in Maine.

Anyway, I have been watching the NH listserve and plotting my visit. I needed 5 more species, and I kept an eye on when a handful of uncommon to rare birds joined the more expected species that I “needed.” Seeing recent reports from the Seacoast – and seeing that my days off will be limited (aka: likely non-existent) from now to Christmas, I decided yesterday would be the day, despite early morning ice that slowed our drive (lots of cars off the Turnpike yet again) and persistent drizzle and occasional light rain.

We began in the Hampton Marsh, where the high tide was pushing Horned Larks to the edges. Check. We then ran into Ben Griffith and Lauren Kras, and then joined them in a Snowy Owl search. Unfortunately, this was to no avail.

Pulling into Hampton Beach State Park, the two hen King Eiders (197) performed nicely. I teased out a few Purple Sandpipers (199) from the flock of 100 or so Dunlin (198), and ran into more friends.

Compare the “Queen” Eider with the hen Common Eider on the right. Note especially the concavity of the bill, the face pattern, and the cooler, grayer tone to the plumage.

After chatting and enjoying the eiders for a bit, Kristen and I grabbed some lunch and then returned to the coast. Snowy Owl would make a nice milestone bird.

Shortly thereafter, I received a text from Ben “Nelson’s-type Gull on Eel Pond,” followed by “Correction – possible Thayer’s Gull.” And off we went.

Arriving at Eel Pond, the bird in question immediately stuck out, and I set about studying and photographing it. While it seemed that people were at least leaning heavily towards a Thayer’s Gull by this point, I had my doubts. But, I also have limited experience with 2^nd Cycle Thayer’s Gulls. I also did not have a better explanation for this odd bird at the time. But Thayer’s Gulls are tough, 2^nd Cycle gulls are a pain in the ass, and a rarity like this (potential 6^th NH record) of course warranted extra scrutiny.

I began to take notes, and even a little feather-sketching. I took lots of photos. Birders came and went. Ben, Lauren, Jason Lambert, and I continued to work on the bird. Kristen headed to the car to check on the Patriots and to warm up. She was clearly the smart one.

There were a series of things that bothered me about this bird being a Thayer’s Gull, and I scribbled those down in my notes:
–          The primaries were multiple shades darker than any other part of the bird.
–          The tertials were extensively marbled.
–          The bill was so extensively pale with such a finely demarcated black tip for a bird that was otherwise not very advanced in plumage.
–          The bill looked rather large and heavy, especially at the tip.
–          The eye color was orange-yellow, not light, but definitely not dark.
– The legs were dingy pinkish-flesh.

While none of these features really eliminate Thayer’s Gull, they are consistent with “Nelson’s Gull,” the name given to Herring x Glaucous Gull hybrids as well. But try as we might, we could not get the bird to fly closer. I never saw it with the wing fully outstretched, but the bird was photographed well in flight earlier.

It was not a big bird, and looked smaller than most – but definitely not all – of the nearby Herring Gulls. Most Nelson’s I’ve seen are noticeably larger, but large gulls are notoriously variable. But look at this shot – it sure doesn’t look small compared to the 1^st cycle Herring Gull on the left! And see that deep build? It doesn’t look at slim and dainty as many Thayer’s look (speaking of variable – and subjective – gull criteria). The head looks rather blocky, and the bill was rather hefty.

Meanwhile, shortly after my arrival and the beginnings of ponder the mystery gull, a Carolina Wren sang…number 200! Yeah, it was pretty obvious to all that my NH birding has mostly been in the mountains, but this was a silly hole that somehow was not filled on previous coastal trips. Mission accomplished. So I went back to pondering the gull. And, with daylight fading and the long drive (especially for Kristen) still ahead of us, we hurried over to RyeState Park to catch up with a Snowy Owl (201), which was one of our real targets of the day. With at least 12 birds seen along the coast on Saturday, we were surprised that – despite the amount of birders combing the coast – it took us all day to see a Snowy (it sounds like a total of 2 or 3 were seen along the coast by day’s end).

Driving home, we listened to the Pats once again stage a come-from-behind victory, and as Kristen departed, I hit our library and the internet for some gull study time. After reviewing my photos of the standing gull, and comparing that to the photos in references – especially Howell & Dunn – and online, I was definitely leaning more towards Thayer’s Gull, as most of my concerns seemed to be accounted for. But I needed to see the spread wing.

And then Ben forwarded me Jason’s photos. My response was simple, “Ewww.” The extensively dark primaries were as extensive and dark as they appeared in the field. While darker Thayer’s can show dark shading bleeding onto the inner webs of the outermost primaries, the outer three primaries on the Eel Pond bird were clearly wholly dark, and the dark was extensive on the next two as well. I just don’t think a Thayer’s can show that. While no single field mark alone can define any gull, this very well could be enough on its own to eliminate a Thayer’s (or, dare I say it, a pure – whatever the hell that means – one), a bird known for its “picket fence” primaries of dark outer webs contrasting with pale inner webs. Adding that with the other features – including the structure of the head, bill, and body – I’m unable to call this a Thayer’s Gull. Short of a DNA sample, it’s a “Nelson’s Gull” to me, although I think there is some argument to be made for this to not be a first-generation hybrid. I sent the link to Jason’s photos (which are far superior to my own) to a handful of friends, and they have so far concurred that this is a Nelson’s-type gull. But, gulls are one of those birds that everyone can have a different opinion on, so I await responses from others. I just hated to rain on the parade, especially since Lauren and Ben were so helpful in my little listing quest that initiated the day.

Ahh, large gulls. The Snowy Owl was easier to identify. I like Snowy Owls.
