Breeding conditions:

At Old Chevak where we made observations on 1-5 June, two Arctic Foxes were seen on 2 June and one River Otter Lutra canadensis on 4 June. No Mink was were observed. Several pairs of Long-tailed Skuas were present at Old Chevak including 2 found nests with one egg each. One pair of Short-eared Owls was seen copulating at Old Chevak on 3 June. No other bird predators seen.
At Old Chevak Bar-tailed Godwits were present with possibly 6 pairs on the Church Island, and 2 or 3 pairs across the creek by the Fishing Camp. It was difficult to determine territorial boundaries - although extensive aerial displays and chases were seen, birds not infrequently travelled more than a kilometre and included areas both on the Church Island and the other side of watercourses. A nest with a single egg was found on 3 June. No data on bird nest survival is available.
