The yellow bittern is a small bittern. It is of Old World origins, breeding in the northern Indian Subcontinent, east to the Russian Far East, Japan, and Indonesia. It is mainly resident, but some northern birds migrate short distances. It has been recorded as a vagrant in Alaska and there has been a single sighting in Great Britain, from Radipole Lake, Dorset on November 23, 1962 – however, the British Ornithologists' Union has always considered this occurrence to be of uncertain provenance and currently it is not accepted onto the official British List.
Region
South, East, and Southeast Asia
Typical Environment
This species occupies freshwater and brackish wetlands including reedbeds, marshes, rice paddies, mangroves, and vegetated ponds. It is common in lowland habitats with dense emergent vegetation. During the breeding season it nests over water in thick reeds or tall grasses. Non-breeding birds use similar habitats and may disperse locally. Vagrants occasionally occur on coastal wetlands far north of the usual range.

The yellow bittern is a small, cryptic heron that spends much of its time concealed in reedbeds, where it can freeze with bill pointed upward to blend with vertical stems. In flight it shows striking black flight feathers contrasting with buff wings and body. It breeds from the northern Indian Subcontinent through East Asia to Japan and Southeast Asia, with northern birds making short migrations. It occasionally turns up far outside its range as a vagrant, including records from Alaska.

Temperament
solitary and secretive
Flight Pattern
short rapid wingbeats with brief glides, usually low over vegetation
Social Behavior
Usually solitary or in loose pairs in dense vegetation. Nests are shallow platforms built above water in reeds; small colonies may form where habitat is abundant. Clutches typically contain 3–5 eggs, and both parents share incubation and feeding.
Migratory Pattern
Partial migrant
Song Description
Vocalizations are soft and guttural, including clucks and croaks from within cover. Males give repetitive ticking or clicking notes during the breeding season. Flight calls are brief and harsh.
Plumage
Male is buff to cinnamon with a blackish crown, mantle, and conspicuously dark flight feathers; female and juvenile are browner with strong streaking below. Feathers are sleek and smooth, aiding a slim, reed-like profile.
Diet
Feeds mainly on small fish, aquatic insects and their larvae, frogs, and crustaceans. It hunts by stalking slowly along the water’s edge or standing motionless to ambush prey. The long, sharp bill is used to spear or snatch small animals. Dragonflies and other large insects are often taken from emergent vegetation.
Preferred Environment
Forages along reed-lined channels, pond margins, rice fields, and mangrove edges with still or slow-moving water. Prefers dense cover, emerging briefly to seize prey at openings.
