Lake Nockamixon

Took off from work a bit early to get some fresh air and look for some birds up at Lake Nockamixon, a large lake about 10 minutes from my house. Juvenile Tree Swallows--sporting Bank Swallow-like chest bands--were active around the lake, as were Eastern Kingbirds near the fishing pier. A distant second year Great Black-backed Gull was late (or early). It and the Ring-billed Gull I saw there were flagged as unusual by the eBird filters. Nice to hear Ovenbirds singing in the woods--don't get those here at the Audubon Science Office.
