观察细节
Flying with the swallows over pond, fairly high (100-300 feet). -- distinct fluttery swift flight (burst of fluttery flapping punctuated by fast gliding) -- long scimitar-shaped wings -- short body and tail (which it often spread in a round fan) -- hair-like extensions to tail feathers visible in flight & photos -- all dark with slightly but noticeably paler throat area (fading to background dark by belly) -- rump noticeably paler -- silent the entire time it was flying Photos. [NOTE: I will check photos to see if I can 100% eliminate Chimney swift, but I think the extent of pale on breast indicates this species.] [P]
