Asio flammeus
June 8 Point Barrow, Alaska
Going up to Bemidji and a little beyond tonight
I saw 5 individuals, mostly about the supply
area, where two females were collected. Both
were nearing time of egg-laying for one had
oocytes (largest one) 12 mm, and the other bird 5 mm.
The first of these two was a young owl and the
second an old one, heavier and with hard bones.
The nasal septum could not be pierced by a
needle to hold in the fingers; a sharp probe had
to be used. In the young bird the septum was
readily pierced with a needle.
June 10 Have seen this morning on trip to central marsh.
June 12 Three over drum stakes, and later one on the
ground in drum area. Birds now seem to
be generally territorial. Two nests found, one
east of L-W and one in L.E. and beach.
June 14 New nest with 3 eggs discovered on beach ridge.
Like the other it is in the relatively rough
edge toward the marsh, on the highest ground,
but locally speaking not at the peak, but beside
a shallow pass in the ridge.
June 15 None at Nuvuk or along the gravel spit,
suggesting that the birds have moved
off the beach to nest and that the non-
breeding group will be small if any are in
this category. A high percentage of nesting
is indicated by the several nests found.
