Calidris puscicollis
25 June Barrow, Alaska - a single bird was seen in a
high polygonized area giving a low flight display and
then landed and fell. A pair was watched for some
time across the gas line W of the Neul of gasoline
ridge. When 1st seen the 7 was chasing a dunlin
and 3X gave a wing up (one wing only) when its
dunlin came near. Sometimes the associated 7 was
involved in the chase. Later a male flew up into the
air to a height of 40 to 60 feet and hovered for 15 to 20
seconds giving a still wing beat, the head level forward,
the tail opened & level, the wing beat rapid and
bluny [illegible], and at the beginning of its
(1 1/4 sec) call "po-oit po-oit po-oit po-oit po-oit
wee-zit wee-zit"
the 'po-oit' note low and rough and the 'wee-zit' high
pitched and buzzy; then it flew down (landing near
a 2nd bird, going into a "grouse posture" and running
at the head (in small circles) of the 2nd bird, calling
"po-oit po-oit po-oit" as it landed; otherwise
it appeared to be silent. The grouse posture was main-
tained for 2-3 seconds, when the 2nd bird flew off, shortly
after which the 7 flew as well.
Shortly after this I flushed the 7 which landed on
a low-polygon ridge. The 7 about 15 feet away got up and
flew over calling "pz-wee-zit pz-wee-zit po-oit it..."
and landed and went into the "grouse posture"
running at and around the 2 for 3-5 seconds, continuing
the call "...po-oit it po-oit it 22222222" the buzz very
soft and the grouse posture lasting longer than the call, and
