Stercorarius longicaudus
20 June Barrow, Alaska; - one seen flying from the FATE
Tower area tower the S end M. Salt lagoon; I landed on the rim of its lagoon for a short time
and then took off by NE across the lagoon
out of sight. The back was a little darker than the
other two long-tails I have seen briefly; tail feathers
vibrated up & down in typical fashion as it flew.
21 June In contrast to the other shearbirds, this species
appeared to be somewhat more numerous today than
yesterday. (Applies to Red Phalarope ?).
21 June A single bird in plumage similar to the one seen yesterday
flew in and landed between M & S Salt lagoons; it flew in from the W and remained 3-5 minutes;
it first preened, then walked over to a polygon and began
to pick up something that looked by cobalt guts
to a bird (carion) and dropped it; I went to this spot chasing
its jaeger away before it had been able to eat this and
was unable to find anything except clumps of
reddish-brown lichen or moss. The tarsi are almost
bluish-white and the rest of the legs & feet are black;
24 June Saw one over family lagoon and one carrying
a lemming high in the air (above), dropped the
lemming, then gobbled it again and swallowed it,
in the AM and two together near the S entrance
to Wohlgeschlag Slough in the afternoon.
25 June A short-tailed individual was seen on two occasions
(about noon & 10 P.M.) near ATE.
26 June A "no tail" bird allowed very close approach on Dr. Pickel's plot.
