Gulls Gone Wild!

17th-19th April – West Haven, CT (click images for larger view)


First-cycle Thayer’s Gull, West Haven, CT 19th April

After Nick Bonomo refound the adult Kamchatka Gull at Oyster River on the West Haven, Milford border, (first found in Southport, CT by Mayn Hipp and Mike Warner a week previously), Oyster River had been given a good going over by a few locals, mainly because it was a great loafing spot for gulls and hosted CT’s only Ross’s Gull in the 80s.

The birds are frequently disturbed here by Joe Public and when flushed, frustratingly often fly off into the sound and despite checking the area, the Kamchatka Gull had not been seen since. Nick and I did find a surprisingly late Snowy Owl along the same stretch of coast. Later that night, amazingly enough, Keith Mueller, birding the same spot an hour before Nick refound the Kamchatka, had unwittingly photographed another Mew Gull while taking shots of Bonaparte’s Gulls. The images appear to show the Eurasian race of Mew Gull, known as Common Gull.

On Friday 17th, I had left work early for a Dentist appt. Deciding to head down to Oyster River on spec, I was just leaving New Haven, when Nick called to tell me Keith had relocated the Kamchatka Gull back at Oyster River. Panicking, I set off only to hit rush hour traffic. Halfway there I got a call that the bird was flushed by a clammer and was not on view. AAARRRGGGHHHH!!! Relief came when Keith called back and said he had it out on the flats. A mad sprint later and the bird showed excellent roosting on the flats.

I spent Sunday afternoon 19th April birding, but  there was no sign of the Kamchatka Gull or any other gulls for that matter. Taking my usual route back to the house, I stopped at the West Haven boat ramp, as I often do to check out any gulls. There were few birds in evidence but I did spot a first-cycle Iceland Gull on the water.


_P9A4672After shooting it for some time, I left. As I was reversing back, I caught a glimpse of a bird landing below the dock, but the metal barricade obscured everything but the underside of the wingtip. It looked surprisingly silvery, but didn’t strike me as Iceland. My spidey sense was tingling, so I stopped the car, got my bins and peered over the barrier to find a first-cycle Thayer’s Gull staring back at me. Holy !!!@@$$$$.


Doing a double-take, I checked off the short primaries with nice silvery fringes, brown, pale-tipped tail and overall bleached, cafe-au-lait plumage. Structurally it was all thayeri with short legs, a slight pot-belly and a disproportionately small, but pear-shaped head. The bill was mostly dark, just beginning to get some flesh-color at the base. Thayer’s retain their juvenile mantle feathers until later in the winter and upperparts seemed to be all worn first generation feathers, again supportive of Thayer’s Gull.

_P9A4882In flight, coffee-coloured (not blackish, or dark brown) tail, secondary bar and outer webs to the outer primaries all screamed..RESULT!!

_P9A4778Nice pale underside to primaries, here the light showing through illuminating the “venetian blind” effect on the primaries.

_P9A4845Note color of primaries and tertial centres being rather uniform and not contrastingly darker as some of the similar, bleached Herring Gulls nearby. What a cracking bird! I’ve always dreamed of finding something like a Mew Gull or a Franklin’s Gull here, but Thayer’s was not really on my radar.

A fantastic few days of birding on my local beaches!
