Appearance:

Resembles a big, black Curlew, but can only be confused with Bald Ibis. Differs from this by longer, slender neck, rounded and feathered head, long legs (trailing in flight) and heavier bill. Bare parts greyish, not red. Adults with glossy green wings. Immatures and birds in winter plumage with white-speckled head and neck. Head and legs droops slightly below horizontal plane in flight, leaving a "hunched" impression. Wing beats faster than herons of same size. May glide longer distances, but does not soar like Bald Ibis. Flight formation loose, diagonal or in single file with undulating movements.

Sound:

Generally silent away from breeding ground. Dry, crow-like "garr garr", may be heard occasionally in flight. At breeding ground various guttural grunts, and piping, hissing sounds.

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".
