To determine whether Pacific Golden-Plovers Pluvialis fulva and Black-bellied Plovers P. squatarola were nesting on the Alaska Peninsula, we conducted field surveys at several sites in 2004. We found both taxa breeding on the peninsula, with fulva in greater abundance. Our findings indicate that fulva nest from at least King Salmon–Naknek southward to Port Heiden, and squatarola from at least Kukaklek Lake southward to Port Heiden. Breeding range extensions (i.e., from previously known nesting grounds nearest the peninsula to the most distant peninsular nest sites) exceed 300 km in both species. We suspect that further ornithological exploration will reveal these plovers breeding more widely on the peninsula than we describe here, and that peninsular breeding grounds will prove to be contiguous with non-peninsular parts of each species’ nesting range.
