Appearance:

Green upperparts and yellow underparts. Sides of bill yellowish, legs slate grey. Short yellow supercilium which connects to yellow lore. Long wings and relatively short tail. The flat crown and long bill gives it a different head profile from Sylvia warblers. Often raises crown feathers. Very similar to Melodious Warbler, but differs from this in pale wing-panel and longer wings. Folded wings reaches tip of under tail coverts, and primary projection is as long as tertials. Juveniles paler than adults, with whitish supercilium. The pale wing-panel extends to fringes of greater coverts in addition to secondaries. Alert and agile bird. Usually hidden in foliage, also when singing.

Sound:

Contact call distinct. A hard, trisyllabic "che-che-fink" , or "che-che-weet" with upward inflection. Song very virtuous and varied. Most similar to Marsh Warbler, but timbre and attack harder and more powerful. Tempo varied with many pauses, but includes longer, and more flowing sequences than Marsh Warbler. Song frequently interrupted by characteristic, nasal, high-pitched squeaks unlike Marsh Warbler. Master of mimicry. Imitations are often repeated several times before changing to melodious motifs or more "noisy" phrases.

Appearance:

A very large, long and slender bird. Bigger than Grey Heron. Plumage grey, with contrasting black throat and flight-feathers. White sides of neck. Tertials forms fluffed, ostrich-like rear end. Red crown visible at close range. Easily told from herons in flight by the straight neck. Juveniles with rufous head, lacking the marked pattern of adults.

Sound:

Powerful, resonant and bugling "kriiiiioooo" in various forms. Very far reaching. Often heard in duet where the female immediately answers the male call at a slightly deeper pitch. Also very vocal when flocks meet.
