26.
24 Dec (cont.) Kittiwakes, two in adult plumage, one
in imm. plumage, and also saw another gull, either a
Herring or Western Gull in Imm. plumage. Checked the
Laysans and Blackfeet. The gull skinned out. Try that
again - The gull was skinned out. The rain continued
on into the night. Cold.
25 Ded. Christmas. We rest, read, and generally relax
all day, only checking the goonies. A new storm is
upon us - rain less today.

26 Dec. Shore-bird and seal census, Laysan and Black-
foot nest checks. The Blue-faced Boobies are much
more active now, and sky-pointing is a commonly seen
event, whereas it was never seen in November. Mated as
well as unmated birds sky-point, and the functions are
different de ending on the status of the birdx. Mateed
birds call their mares from a short distance away to the
cleared platform, whereas unmated birds sky-point to any b:
bird flying over the colony to attract them. If one
bird flies over, as many as 6 or 7 birds may sky-call to
it as it circles overhead. U. pt. - 4 Glaucus-winged gulls, 1 ad.
Black-legged Kittiwakes.
27 Dec. We bagan blood work today and have worked out a
reasonable system, carrying enough equipment for doing 24 1
birds. The work is complicated by the fact we are also
doing weigts, measurements, and ectoparasites on the
Laysans we are weighingx bleeding, so it takes many
operations to complete one bird. We found one Laysan
with an oozing sore on back, and the skin was eaten away
exposing the bones of the pelvic region. Two birds
were seen this way yesterday, one was killed as it was
almost dead, one being able to look down into the insertio:
of the humerous in the pelvic girdle. The whole looks
gnagrenous and smells badly. We collected blood from the
sick bird and collected it as a specimen for later auto-
psy.
After dayk we walked to south point and there caught
a Glaucus-winged Gull, got a Mckbee card on him,
collected reams of lice from the head just behind the eyes
and kept him overnight. He regurgitaed a rat in the
lab, and remains of another were later voided. He was
weak and very light, having come in with the other 3
after the big storm. There are 5 Glaucus-winged Gulls
now on the island (one was collected and skinned), and
