Appearance:

Very similar to Common Swift, and often difficult to identify in the field. Seeing the birds against a darker background, as opposed to the sky, brings out some of the characters more clearly. Generally paler and more sandy brown than Common Swift. Differs further from C. Swift by: Rounder wing tip (outermost primary shorter than the next), slightly broader wings, broader and flatter head. White throat patch bigger and more prominent. The face seems paler, which brings out the dark eye-mask. Back slightly darker than upper part of wings. More contrast between outer and inner primaries. Underparts with more pronounced scaly pattern. Flight less acrobatic, with slightly slower wing-beats, more frequent gliding and much less twinkling turns.

Sound:

Similar to Common Swift, but usually very helpful for ID. Almost di-syllabic, with marked accent on second syllable which rapidly drops in pitch, "srrrree-aah". Common swift has a more even call, with accents on first part, without the sudden pitch-drop.

Appearance:

Light grey upperparts, black wings and tail with white patches, white underparts and throat. Broad, black eyestripe not reaching above highest point of bill. Bill long and medium heavy (not as heavy as in Lesser GS). White patch at base of primaries varies according to subspecies. Black part of tail most narrow at base. Juveniles less pure in colour, with faintly barred underparts and buff fringes to greater coverts.

Sound:

Alarm call very harsh, nasal and noisy. Dry and not as deep or resonant as crows. Song varied. During breeding season a varied subdued song is heard from both sexes. Territorial call before breeding starts is simple, loud and resonant. Consisting of pleasant sounding single or double syllables, with well defined pauses and peculiar harmonics.
