One male behind the drum was
heard to give a gurgly-type call which
seems to be the warning note. When
another male entered his territory,
both birds flew side by side, both
giving their aerial display. Three
birds (all ?) were seen in the grassy area
just north of Wohlgeschloss's Slough.
One bird (A) flew to the west and encountered
bird B. These two flew about 40 feet
giving their booming call. Then A flew
back to the east and encountered
Bird C. These two proceeded in the flight
display until A turned back toward
B and the whole thing started over again.
24 June, Barrow, Alaska
One male seen chasing two Baird's Sand-
pipers away from a snow goose
area alongside a pond. These two piper
halfeen fighting (a courting?) - every
display toward each other and lower
call) as he ? darted toward them,
uttering his harsh gurgles. The two birds
immediately took flight and moved
about a hundred yards away. The
male chased them for about 50
yards and then returned to a mound
where he settled.
