The record of a probable wild branta canadensis parvipes from Japan

Abstract

A vagrant individual Branta canadensis visited Hokkaido on migration in spring 2006. We present details of its eventual identification as Branta canadensis parvipes and our observations of this rare visitor, which has not been formally described from Japan. We describe its staging at two separate locations in southern and northern Hokkaido, its association with other geese, and its length of stay. © Yamashina Institute for Ornithology.
