Gözlem detayları
At 0914 2 Least Terns appeared over pond and for the next 16 minutes they flew with erratic grace over the pond, diving repeatedly with absolutely vertical dives into the water. At 0929 they were gone as suddenly as they appeared. Very small, white terns, yellow bill, black cap but with white forehead. Silvery gray on back with darker line along leading primaries in flight; white underneath. Never saw leg color. The tail was not forked, only gently curved. Pictures attached are not great, but the sum of them catches field marks.
