Appearance:

Large and robust warbler with plain plumage, except for the characteristic cap (black in males, rufous in females and juveniles). Upperparts greyish brown and underparts pale grey. Vent white. No white in tail, as opposed to all other black-capped Sylvias in the region. Easily confused with Garden Warbler if the cap is not seen.

Sound:

Song pleasing, varied and loud. Sometimes very similar to Garden Warbler. A typical phrase starts with soft, staccato chattering and mimicry, which after a few seconds changes to a much louder, pure and resonant stream of notes for about 3-5 seconds. No fixed motif, but may end phrases with recurring notes. Often deviates from the characteristic type of song, and identification from song alone may be impossible. May sing first part of song for extended periods without ever reaching the characteristic ending. Alarm call a hard "check", similar to Lesser White-throat. Sometimes with an additional hoarse and nasal "cherrrr".

Appearance:

A small, compact martin with short, forked tail and pure white rump. Underparts shiny white (including throat and vent). Upperparts dark with shiny metallic glow to head and back. Juveniles overall more dull, with white tips to tertials and dusky, brownish upperparts. Flight determined and steady. Glides more than Sand Martin, with less frequent change of direction.

Sound:

Contact call a rolling "krreet". Similar to Sand Martin but noticeably dryer, more rolling and less raucous. Typically varies the pitch of the call more. Song a merry improvisation of chirping, contact call-like sounds (sometimes recalling a budgerigar). Warning call a sharp and plaintive "tsreee".
