Jonich 1953 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.
