The Wilson’s Phalarope (Phalaropus tricolor) and the Yellow-bellied Sapsucker (Sphyrapicus varius) are relatively recent additions to Alaska’s avifauna. The first observations of the Wilson’s Phalarope in Alaska were made in 1962, at the Columbia Creek Flats on 20 May (64° 26′ N, 141° 25′ W) (Kessel and Springer 1966) and at Barrow on 9 June (Pitelka 1974). The Yellow-bellied Sapsucker was first observed in Alaska on 16 June 1976, near Northway Junction (Kessel 1986). Kessel and Gibson (1994) suggested a northwestward range expansion for the Wilson’s Phalarope into Alaska, and we support that conclusion by reporting the first documented evidence for breeding of this species in the state. Here we also report on the westernmost breeding and occurrence records for the Yellow-bellied Sapsucker and suggest a continental westward range expansion for this species.
