Twelve birders spent a delightful morning at Cupsogue Beach County Park with Eileen Schwinn, an expert Suffolk County birder who has logged many hours at this location. We started the day with a scan of the saltmarsh from the parking lot. Both Saltmarsh and Seaside Sparrows were seen, as well as a Willow Flycatcher taking advantage of a large hatch-out. We then did a brief sea watch from the platform leading out to the beach; it yielded a few shearwaters, likely Greater or Corey’s, but they were too distant to identify with certainty. On the roadway out to the bay, a Merlin was observed, along with several passerines.

We arrived at the bay about two hours before dead low tide and found an abundance of terns, gulls, and shorebirds on the sandbars and mud flats. Hundreds of Common Terns and about a dozen Royal Terns were present, in addition to a good variety of shorebirds. We were delighted to see a Marbled Godwit foraging on the edge of Spoil Island, and a Pectoral Sandpiper was spotted near the area favored by the Royal Terns. Aware of an approaching storm, we wrapped up around noon and enjoyed lunch together at the snack bar before departing.
