Appearance:

Summer plumage unmistakable, with black underparts framed in white, with white and grey-speckled upperparts. Diagnostic in all plumages are the black armpits, which are clearly visible in flying birds. Also shows white wing-bars and very pale tail, with some barring. Winter-plumaged and juvenile birds speckled in grey with white underparts. Can be mistaken for Golden Plover. Especially the juveniles, which may have faint golden tone to plumage. Note instead heavier bill with swollen tip and bulkier body.

Sound:

Contact call diagnostic. A plaintive, drawn and trisyllabic (but continuous) "kleeooowee". Pitch falls on second syllable and rises on last.

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.
