Jonich 1953 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.
