观察细节

Flying over the pond. In comparison to adjacent swallows, slightly smaller with dark gray above paler below, especially the throat, upper chest and rump. Slim pointed wings with a faster stiffer wing beat than swallows; occasionally fanned tail. Three was the most seen at once. Species present here the last three summers. Poor photos
