Stercorarius longicaudatus
27June Barrow, Alaska - 2 single birds and a "flock" of 3
were seen over the Barrow area and 1 was seen over the
VOTh area, another over Family Lagoon. It (the last)
was in a chase involving a Br. Pomarine and called
loudly, the calls much higher than Pomarine and longer,
like the protests Pomars give near the nest. All seen today
had fairly good tails except the 1st bird which was rather
dirty below and had short "tails".
28June One seen towards the N end of Family lagoon was
going after a very dead, small Lemming, and was
bothered (but not actually attacked) by a pair of
Pomarines in the area. A medium-light and a
very light individual were seen near the barrow
area.
29June Only one seen in the morning but at least 8
(3 over this lead, 2+ near Family lagoon, and a group
of 3 including one subadult near Bullton's area).
I Toured a call which sounds like a Amer. [illegible]
(whistled "wee kee") to an individual of this species
being chased by a Pomarine J. near Micomet
in the evening.
30June An adult + subadult seen over Central
Marsh in the morning.
2July An adult and a slate-tailed subadult seen over
Micomet Marsh in the afternoon.
4July at least 5 sitting on the ground between S+H. Salt Lagoons
and 2 seen over VOTh slough. 2 were seen along this ice
on this lead, flying slowly about 10 feet up and dropping
