Asio Flammeus
June 4 Point Barrow, Alaska
There is much variation in the manner of
flight of the short-eared. At times the wing-
stroke is especially deep and the body seems
to move up and down. At other times the
body remains steady and the stroke is not
so deep. Sometimes the bird sails. The deep
stroke is used in more powerful flight, as
in gaining speed and altitude.
June 5 One over the drum area this afternoon.
June 6 When two were over the drum area in the
early afternoon I was attracted to them by
a sudden clapping of wings, 3 or 4 strokes
in rapid succession. Looking up I saw
the two birds circling and moving away
from one another. They continued to fly
about, drifting out over the tundra.
June 7 Two or 3 seen on trip to Nenrich; more there.
June 8 Two this morning along beverage line 5. of
Brittonwanigan. Along this route and to Khonik
Lake this afternoon I saw 6 or 8 short-eared.
When one pair was flying about, one bird
suddenly clapped its wingtips together in a
rapid irregular vibrant clappaty-clap, per-
haps 4 strokes given, when the wings were
at the bottom of a deep flight stroke.
The birds perch here and there on the
tundra and seem to be settling to nest.
