JPMcNas 1980 Colidris melanotus GRID 3, NARL, Barrow, AK 28 June (cmt'd) one receptive Q (1c. with swollen vent) in tree (3,5) area - M'Caffrey later found her nest (PS21). Limp was there with her, remaining quiet. 1410 - Y:VM feeding near (-3,11), ~300 m from her nest 1630 - Another new PS nest, then me near (6,8). This nest has only 3 eggs but nevertheless the Q is putting up to a local P who is displaying to her, and hooting over her. Q 1550 Y:VM:- chased C. algina away from her nest (~15 m away) 1630 - I finally found 6W:6M and began tracking 1747 - an intruding transient P? close beside 6W:6M. He starts L16C/RC and quickly begins RC. She puts her tail down, ruffles feathers, much like winter hooting display. Limp came in and chased him off. Limp has a real limp + has difficulty in displays because it is so pronounced. If Zahavi's handicap principle is correct then can we expect all P? to show a limp in the future? Not only that - he rarely hoots, and finally, he has a 2? that is arched+ so badly so that he is readily recognizable in flight.] Summary - 6W:6M spent 2 hrs cruising rapidly by foot over much of Limp's territory. She spent the 1st 27 minute, however, on P? 's area. For the duration Limp remained with her. He hooted once, reached SQUAWK once, and RC once. 6W:6M investigated 2 separate nest areas. In their interaction several times she came to him from 10-20 m away as he gave L16C/RC. 29 June While I found Limp as soon as I arrived at 0400 this am, I did not find 6W:6M until 0526. Most likely she was just roosting quietly quickly because I found her right where Limp was all along. Began tracking immediately. By 0505 about all I saw was one [order fight involving Limp, plus two high P? ? chased away in the sky over the grid. Otherwise [illegible] quit.
