Appearance:

Small falcon recalling both Kestrel and Hobby at a distance, but most likely to be confused with latter. Adult male unmistakable with ashy grey plumage and rufous red "trousers". Colour of trousers not always obvious, but silvery upperwing often visible in flashes at distance. Adult female also distinct with almost unstreaked buff underparts and under wing-coverts, buff neck and crown, dark mask and white cheeks. Immature most likely to be confused with Hobby but differs in barred upper side of tail, pale forehead, white (half)collar, contrasting dark trailing edge to wing and more striking fringes to coverts. Underparts also less heavy streaked. Flight profile similar to Hobby but tail slightly longer and more rounded. Hunts insects in flight, but in contrast to Hobby, hovers frequently and with deeper wingbeats than Kestrel.

Sound:

Flight call very similar to Hobby, a wryneck-like series of "kew kew kew kew", each call falling rapidly in pitch. Sometimes given in a harsher more staccato version. Very vocal at colony with various squeaky and whimpering begging calls.

Neck with incomplete black band, creating contrasting, jagged edge. Heavy, goose-like flight.
