Amaurornis phoenicurus (Pennant, 1769)
|Common Names:||White-breasted Waterhen|
Found throughout coastal areas in Singapore and its offshore islands.
The White-breasted Waterhen frequents damp swampy vegetation in rural areas, orchards, marshes, mangrove, grassland, gardens, parks, canals. It is not found in the interior of forest. Its loud, repetitive croaky call can usually be heard in the evening. It regularly keeps its feathers in top condition by preening and sunning.
A pair passed a cockroach to and fro for some time before one ate it up, a strange feeding behaviour.
The nest is built at the edge of a pond or ditch. The clutch of 4-9 eggs are incubated for 20 days by both parents; chicks leave the nest as soon as they are hatched; and both sexes care for them (Taylor, 1996). The chicks are initilly all black, to gradually develop patches of white on the underside. It takes about six months before it develops the adult colours. The appearance of the sub-adult can be viewed HERE.
