Calidris pusilla
13 June Barrow, Alaska - there were at least 6 birds in the
panel area today, including a few birds giving
the flight song, but little ground display was seen.
Saw 3 birds together giving the flight song. Only
three side Family polygon around the same, fewer
individuals evident than yesterday and only a
little flight display. Animal appears to perch more
than anything else and tend to feed in bare,
highly disturbed areas.
14 June Only a few birds seen in the raised areas along
Elson hogon. 1 or 2 flight songs seen.
15 June no change from yesterday; few birds in the panel area.
16 June one seen flying by the AAAC3 area in the A.H., and
two rather silent birds by Elson hogon in the afternoon
17 June almost no display today, but some cool-sounding
vocalizations heard as birds flew around.
Very scarce now compared to June 12-13.
18 June Considerable display late in the day near the
outer part of the panel area. The display differs
from the other Calidris (esp. Bairdi) in that the
bird goes rather quickly into the "tuck tuck tuck" motor boat displays without any other finalized
vocalization; they generally glide with the
wings in a V and the other call notes are
not as grating as the other "peep". Still seen several
0's together.
