Getting to Cupsogue County Park required a 2hr40 drive in the early morning via that least desirable of roads - the Belt Parkway in NYC. Nevertheless at 5am on July 4th the traffic moves fairly well and I was one of the first birders at Cupsogue, although by no means the first person in the parking lot - the bay side is also popular with fishermen. It was extremely foggy, so I left the camera in the car and just took the scope. While waiting for the fog to clear I was watching Short-billed Dowitchers, Willets, a Spotted Sandpiper, Common (many) and Black (1) Terns, and a hybrid Dunlin. This hybrid had been named as a White-rumped x Dunlin hybrid. To me while one parent was definitively Dunlin the other could have been White-rumped or Western especially since the hybrid showed some arrow-shaped spots on the flanks. Nevertheless that hybrid is not unprecedented.
Adult Red-necked Stint, NY, July 4th 2013
An excellent look at a rare shorebird that I'd only seen once before as an orange dot on the far side of the East Pond at Jamaica Bay WR the same day that I found the adult Sharp-tailed Sandpiper (August 3rd 2008). Given that we've had the wettest June on record, Jamaica Bay itself is going to take a very long time to draw down - long enough to perhaps eliminate chances for Asian shorebird vagrants there this year.
This is an eBird data query of RN Stint sightings for July-Sept in the last decade.
Other birds of interest: first summer Arctic Tern; Roseate Terns; several basic-plumaged Red Knot; Dunlin; Least Sandpiper; Semipalmated Sandpiper; Semipalmated Plover; Black-bellied Plover; Black Skimmer. The Arctic Tern is a NY state list bird for me.
Then all that was necessary was a 2hr45 drive home via the Verrazano Bridge ($15 toll these days).
