Report on a study of the only known breeding population of the endangered Aleutian Canada goose (Brauta canadensis leucopareia) from 1974 to 1977 at Buldir Island, a western Aleutian island, Alaska.

This report presents the results of the first study of breeding Aleutian Canada geese, the endangered race with a single known breeding population at Buldir Island, Alaska. It was bred on most of the Aleutian Islands, but was reduced to a single breeding site after introduced foxes preyed on these geese on other islands.

"The purpose of the study was to evaluate nesting chronologies, population sizes, and habitat utilization of birds, particularly Aleutian Canada Geese (Branta canadensis leucopareia) and breeding seabirds."--Leaf [1].
