Code 1957 Buteo lagopus 30 June, Umiat A pair was seen flying around in the vicinity of last year's nest on Umiat Mt, but this nest was empty. Nor indeed could we find an active nest anywhere along the bluff. The birds soared around up high and did not set in the least agitated by our presence. I think it is safe to say this pair is not breeding this year. Last year they produced 2 fledged young. 1 July Colville River - 3 were seen flying at intervals between Umiat and Colville Bar and 4 in the air along the Olaunagokik - these were seen from the plane. None were present at the bluffs or the copper Olaunagokik gyps aerie, where they were last year, or at Stawfish Bluff or at the Double Knife Ridge Bluff - all of which had nests last year. 7 July Colville River - more above Olaunagokik Nest #1 - Lower Hillik Bluff - inaccessible stick nest - 200 ft down below turf on a shale- muck talus and 100 ft above the river on top of a stack of shale. Both birds present, screaming & diving. 1 was flushed off nest when we arrived. About 1/4 mi up river from a Peregrine aerie with one added egg. NW facing
