JPHugers 1976 Calidris melanotos GRID 3, Barrow, Alaska 25 June 0430 - tracking & 6/25/76-1. writing now. The resting & characteristically settled down as is this individual in a sheltered spot behind a clump of Poa or his around, face to the wind, and tucks his feet to bill in his scapulars. Although he will close his eyes, he is actually, aware - perhaps not circumspectly, but certainly much attentive, of going on about him. Two events are sure to elicit some sort of response - low overflight by a jaeger, in which case the bird ducks; or vocalizations by other waders - be it a loon or a schrunk. The vocalization usually provokes an alert posture, the & abruptly coming out of the resting posture and looking about with neck upraised [illegible sketch] GRID 2 140 - photographing border interaction between 2 & on grid 2 ((10, 19 region). The parallel hover- maneuver entails repeated forward motion, often alternated between birds such that one moves for a second or two, then the other, and the inch forward like the navigating aid course - charting instrument used by nautical men to plot their courses. The & (move) and move forward, sweeping their head up with them as they move. Then one will pivot about and match the other wing. Occasionally they will, either one or both, break off with displacement feeling, poking at the surface within a meter or two of the other bird, only to begin again on parallel march if the other bird continues forward. CHASE flight - very characteristic of vauid powerful wing beats, fly low, and in a very direct path. 28 June Flux !! & 6/28/76-1 was inordinately active this am. - see tracking acct. An unestablished & was trying, it seemed, to gain a foothold between 6/28-1 and its neighbor to the NW. Much hooking, incredible chasing, fights, border displays. RG tracked during run on GRID 2 - South central area, and reports that there have been large charge flurries in semitomy size + shape
