Stercorarius pomarinus
24 June Barrow, Alaska - two seen earlier (both with 2 eggs)
early had the same while the new nests were
both 1 egg nests. Saw no copulation and no fight.
but much aerial display. Glaucous gull success-
fully robbed jaegers of ternning on two occasions.
None of the birds seem bombed me. One of its
pairs have a black 8, the rest of the 5 pairs are
all light birds.
25 June Still good numbers in Central Marsh, and widely
distributed but not very active elsewhere. Not many
on Family hagoon. Found a pair passing over a
scape 6 feet west of a pole left over from last
year.
26 June Saw birds in "regurgitation" postures on 2 occasions
and believe they are casting pellets but couldn't
verify this. Most nests now seem to contain 2 eggs.
See Snowy Owl. Only about 1/2 as many on Central
Marsh Now, due to the flooding there.
27 June Found 2 nests and saw 2 other s. thing 8's which we
didn't check. The nest near Voth Slough had a black 8,
and the nest in the NORTH area was observed by a 9 which
repeatedly dove at me the feet dangling and yelling
wildly. There are about 20 or so out in Fresh Lake
and in S. Salt hagoon but do not seem to be the
territorial birds that were present earlier. Found
3 sets of Pom. jaeger wings dissociated from bodies.
28 June A nest with 2 eggs near a pool in Miceonet Marsh:
Some pairs don't seem to be settled yet. (see journal for today).
