Childs 1958 Falco peregrinus 13 June Pitnuzea River, Cape Sabine, Alaska when we ran the kaylins at 2200 we saw a 67 (?) chasing a longspur but he could not get it. He would dive and then drive and repeat but the prey eluded him. 24 Jun One seen with mottly prunian along the bluff east of river mouth 5 July Pitnuzea River, 16 miles SE Cape Sabine, Alaska Again is using an old nest across the river from our camp in a V-shaped canyon in the bluff overlooking the old river bed. There were no eggs in the nest yet. We wasted our usual number of shells without apparent damage. 6 July Still present at nest. See Roughley's note. Trial again to shoot these birds with no success. They are very wary now. Found their nest to contain 4 very small young located about 15 ft away from the above old nest. These well hidden in the edge of the bluff, not down on the slope as others have been. Our predator could get to it. old nest 21 July Pitnuzea River, 2mi SE Cape Sabine, Alaska Tote shot one several miles upstream 23 July - another one at same spot and missed a third.
