Dunlin on the run

On the way to work this morning I found a nice breeding plumage Dunlin at Pine Run. This sandpiper, formerly known as Red-backed Sandpiper or Black-bellied Sandpiper, is a rare migrant in Bucks County, seen only a couple times a year if that, so a nice way to start the week. Also saw my first Solitary Sandpiper of the year at Pine Run, and a lingering Bonaparte's Gull at Peace Valley. (photo: USFWS)
