Stercorarius longicaudus
1 June Made River Coal Mine, 157°25'W, 69°29'N, Alaska
A nice adult was pushed along the creek
near the village. When it was approached it
flies off to the area where two Parasitic Jaegers
have been hanging out, and was attacked by
the jaegers. It flies off. N only the rleade.
seeming to hover once Kestrel-like over the
creek a mile N of camp.
2 June One seen near the blowing dunes N of camp
about 11:00 AOT and one over camp about 3pm.
Two circling over the "census" plot area and tenable
flies over me silently in the evening, but they
don't appear to be staging around.
3 June One or two present near the village, seen in
flight only. One seen 1 mi. S of camp about 10:24.
5 June Two were scraping the meat off an old Ptarmigan
kill that its quills were working on 1 June. Three overall,
a little skin with meat on the leg bones. One bird would
gulp this and pull, occasionally knocking off bits of
meat which the other bird picked up. When they pull
the tail feathers really bopped up and down. They walked
a funny waddle and one, which seemed nervous, would
"paddle its feet" up and down. The two worked on
the carcass for several minutes. 4 longtails were
chasing the local Parasitic Jaegers near the village,
circling loudly, and diving at and striking downwards the
feed. Later Two longtails were chasing these Parasitic
Jaegers one or two others trying
which were pushed on the village ridge near the cemetery.
