Rissa tridactyla 26 July Barrow, Alaska - all birds on the Chuckchi Sea flying east, one right along the shore and the others farther out. All were adults. They were mostly in groups, widely scattered, of 3-5 but a group of 13 saw and 1-2 of up to 10, and one of its large groups was quite vocal, calling "it-a-ake" loudly and repeatedly as they flew. 27 July Most were seen between 4 and 5 pm, about 3/4 flying west, the rest east. The largest group was 32. All but one immature good plumaged adults. Two flocks of about 12 calling as yesterday. One seen to circle as if to feed, flight down then continue on out. None as close to shore as the one yesterday but the wing tips could be seen on all. 28 July Flock of 8 adults flying east fairly far out, 29 July one adult flying east fairly well out.
