Calidris albes 14 June Barrow, Alaska - The Sanderlings seems to be at it this year again, in the Barrow Area. 3 birds flew up from a grassy area about 1/2 way out; I soon disappeared, went the other two were involved in a long fight, which began as a low chase over the ground about 3 feet up. The pursuing bird called "tsoiq tsioig tsioig....", a low barely audible (from 20 feet) call. The birds landed and one went into a pronounced hunched like the Semipale. I saw on the Cenway prof. at Pleasle River, and would alternate chase with two jump on the 2nd bird, which seemed to be fighting birds. The object of contact seemed to be to jump on the back of the opponent and grab it by the nape, occasionally pecking at the opponent's head. When one bird had had enough, it flew off (after 3-5 minutes of fighting) and then came back about 2-3 minutes later for a 2nd fight about half a minute long. Here, a chase with the pursuing bird giving a rapid "tsoiq" call. They landed about 50 feet apart this time, and no more fighting was seen. The "tsoiq" call is rather semipale like, and the fighting is probably characteristic of many of the calidines. [illegible] aggressive hunched posture
