Long-winged and elegant, but looks less powerful than Eurasian Hobby, with which it may associate while hawking for insects. Males unmistakable, females distinctive. Juveniles can be confused with young Hobbies, but note juvenile Red-footed's barred uppertail. Often seen perched on telephone wires and posts. Nests in colonies mostly in old corvid nests, often of Rooks. Hunts over open and semiopen habitats, often near water.
