The ambition was fair, even promising. Two days previous a Black-tailed Gull had been spotted and nicely photographed at Herring Cove Beach next to Provincetown. Look up this gull in a reference, if you can find it at all, and you will be impressed with how little likelihood there is of one showing up anywhere near Massachusetts. I was told this one was probably the third or fourth record in the state. A lot of small pinkish shrimp, like krill, were either in the shore waves or already washed up on the beach there and around the corner at Race Point and lots of gulls of many sorts had shown up to devour them with little effort. Lots of gulls would translate, according to one observer, as about fifteen hundred birds.
Anyway, I wanted to attend a monthly meeting for serious birders held in a small auditorium in a biology lab building at Harvard. The principal speaker was someone I wanted to meet, because she orchestrates a lot of the research on Red Knots (please go to the “Crusade” page above) that happens out at Monomoy, just south of the elbow of Cape Cod. Her crew actually censuses the knots feeding in certain measured plots, checks them for identifying leg bands, tests what their proximity tolerance is for human activity; and they even take core samples of the top few inches of the sand/mud to ID and count what prey items lie within.
Since I was headed off-Island anyway, it made perfectly good sense to make a run up to P’town to find the Black-tailed Gull. A no-brainer, if I could find the time.
This is becoming a shaggy-dog story, because I did not see the sacred bird, even though I know it was in the ‘hood that day. I also went back the morning of the following day en route – if you can call it that - from Cambridge to Woods Hole and the Vineyard. That’s how it goes in birding. I gave it my best shot under the circumstances. But my blogging is an excuse to put up bird photos anyway, so, as I waited for the rare one to cruise by or land at my feet, I took some shots of Ring-billeds at the parking lot and of the overall gulls-on-the-beach scene.
From the reports of others on site and from my own observations the following seabirds were logged from shore:
Pomarine and Parasitic Jaegers
Greater, Cory’s and Manx Shearwaters
Common Terns
Gulls – Black-legged Kittiwake, GBBG, HEGU, Lesser BBG, Ring-billed, Laughing, Black-headed, Bonaparte’s, Little and, somewhere, a single Black-tailed to round out the numbers. Ten species at one spot! Actually, I think it’s eleven, because someone mentioned a Kumlien’s/Iceland Gull in the mix as well. (Subsequent reports of the profusion of gulls on and off the Provincetown beaches include a Glaucous Gull - so it’s a dozen gull species - and both Forster’s and late Roseate Terns.)
There were also small numbers of White-rumped Sandpipers mixed in with the Sanderlings, as well as two flocks of Snow Buntings and a few pipits and siskins overhead.
