R.B. Hamilton 1965 Calidris alba June 15 Barrow Alaska: One bird was observed displaying in the Barrel area S of ARL. It would hover in one spot about 25 ft. off the ground for 2-3 minutes. The wings were held stiffly and did not rise above the horizontal. They did not appear to move more than an inch with each with each wing beat. No sound was heard but that was almost surely because of the wind. Later this bird was observed being chased by a Baird's sandpiper. The sandpiper had the feathers as its back raised and its neck contracted. The Baird's sandpiper seemed to be in a normal posture. Later the sandpiper was observed chasing the Baird's sandpiper in the air. The sandpiper was collected to make sure of its identification. It is felt that this bird was observed on June 13 with the behavior mentioned above. It was not identified then however. June 17 At least 14 sandpipers were observed feeding in flocks at the N end of the Britton Area. These birds were flighty and difficult to approach. June 18 Two sandpipers were observed in aerial display in the Barrel Area. They were not found in the afternoon. Four more were observed in the Britton Area. June 19 Four sandpipers were observed in the Britton Area. June 20 Two sandpipers were observed in the Britton Area. June 21 One sandpiper was observed in the Britton Area.
