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.

Appearance:

Dark, pale and intermediate morphs. Pale birds more common in northern parts of species range, darker morphs more common further south. Elongated middle tail feathers (projection comprising about half the total tail length), but not as long as in adult Long-tailed skua. White patches at base of primaries, both on upper and underside of wings. Dark morph chocolate brown with darker hood. Pale morph with white throat and belly and incomplete breast band. Relatively marked transition from pale belly to dark vent (as opposed to Long-tailed). Size close to Common Gull. Flight powerful, elegant and falcon-like. Juveniles with short but pointed middle tail-feathers. Confusion with other juvenile skuas very likely. Differs from Long-tailed in prominent white base of most primaries on upper side of wing (not just the first few feathers). Lacks the double white patch of Pomarine Skua's underwing, and shows less contrast between back and rump. Wings broader than Long-tailed but narrower than Pomarine. Approximately equal to distance from wing rear edge to tail-tip (projections excluded).

Sound:

Mostly heard at breeding ground. Most characteristic call is a mewing, kittiwake-like "aeeeee-ah". First syllable drawn-out and rising in pitch, and followed by a deeper conclusive second syllable "ah". Lacks the introductory double accent of Kittiwakes ("kitti-wake").
