观察细节
Thinking Common on this one. Seems to be a 2nd year bird with worn outer primaries, fresh inner primaries and worn secondaries. The black worn outer primaries contrast with the gray fresh inner primaries and seems different than what I’d see for Forster’s. No pale primaries like on a Forster’s. Spread tail shot looks a little black on outer retrices. Bill seems pretty dark than what Id expect for Forster’s.
