A trip to the local duck/gull hang-out revealed four Greater White-fronted Geese (Anser albifrons). While this species migrates over Portland in large numbers, it is always a rare treat to see them here in winter.
These birds are examples of the smaller subspecies (A.a. frontalis). The larger, rarer “Tule” White-fronted Goose (A.a. elegasi) also passes through Oregon, with some spending the winter in the Klamath Basin.
These birds were all immature, lacking the black speckles on the belly seen on adults, and showing a blackish nail on the bill.
