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

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
