Description

A survey for nests of Aleutian Canada geese Branta canadensis leucopareia was conducted at Agattu Island in June 1990. The coastal fringe on the eastern and southeastern portions of the island contained at least 5356 nests, and we estimated that over 200 nonbreeding geese may have been present. Most pairs began incubation during the last week of May and the peak of hatch occurred the last week of June. The average clutch contained 6 eggs, and at least 77 of the eggs hatched. At least 1 egg hatched in nearly 95 of the nests, so overall productivity in 1990 was excellent.
