Had a chance to visit the Assateague OSV zone for an hour or so late 
Monday morning on the way back from a North Carolina pelagic trip. 
Visibility was limited by fog, making seawatching for distant Brown 
Boobies problematic, so I focused my attention on closer birds. Notable 
were:

-- An adult Sandwich Tern with a juvenile still begging for food from 
the adult. Both sitting up close on the beach (around kilometer marker 25).

-- four breeding plumage Black Terns flying over the ocean and one 
flying over the marsh/flats at Fox Hill Level.

-- six Lesser Black-backed Gulls

-- two Caspian Terns among many Royal Terns on the marsh/flats at Fox 
Hill Level

-- I sighted 17 Cattle Egrets altogether in Worcester County at three 
locations (including two at Fox Hill Level).

-- Piping Plover, Whimbrel, Western Willet

-- Roseate Tern candidate (only a brief distant look, unfortunately)

Tried to swing by Skimmer Island but torrential rains intervened that 
overwhelmed the drainage system and briefly flooded some Ocean City 
streets with 6 inches of water (!).

Good birding!
