Last time it was arguing Piping Plovers -- this time cranky American Oystercatchers!

After spending a morning looking for terrapins without luck, I ventured back to the Arverne Piping Plover Nesting Area with higher hopes.  I wasn't disappointed.  Immediately I heard -- then saw -- an incredible display between three oystercatchers, and soon realized the possible reason for the scuffle: appears that a breeding couple were protecting their fledgling.  Never saw a young oystercatcher and it was quite a treat!
