P. D. Bevendicht 1965 Colidius alpinus 24 June Barrow, Alaska - the amount of wind. One was chased for some time by a Golden Plover, g.p. 25 June Birds seen in the morning were widely spaced and seemed to be either in pairs or singles. A little arrival display was seen and heard, this being one of the more vocal species encountered on a very quiet morning. On one occasion 3 birds were beginning seen in a prolonged chaced. Several birds begun the primary molt were seen in the afternoon - a displaying ♂ missing the 1st inner primary, 2 displaying ♂ (separated) missing both inner primaries, and 2 silent birds (except for short flight and flight call-note) missing both inner primaries. The molting birds all seemed to be alone, but several non-molting singles were also seen; one of the molting displaying's was with a non-molting bird that gave a very short display, and one chase involving a "good" pair + a molting ♂ was seen. The flight display consists of two segments: the bird flies to 30 to 80 feet up and hovers giving a low, rough, fry like "drroooos"; 3 to 6 turns (at present), then glides or flaps like a Spotted Sandpiper moving usually down giving a rough, descending call "Wreeeeeeee" of variable length (0.5 - 1.5 sec.) and thus repeats or lands. One was seen being chased by a White-camp, and did not fight back.
