觀察細節
An unexpected bird I heard while going in to campus to finish up some work. Flying quite high (100ft+), wheeling around with bobbing flight pattern. Calling almost continuously every few seconds, as in recording-strange sound was what made me look up in the first place. Bird was generally dark from below, with pointed wings, somewhat long tail and a noticeable white stripe along the inside of each wing near the bend.
