This species is partially migratory or nomadic, making short migratory movements in China, India and Japan, and irregular seasonal short-distance movements in Africa corresponding to feeding- and breeding-habitat requirements1. The timing of breeding varies geographically although the species is known to breed during or immediately after the rains in Africa1. It usually nests and forages in solitary pairs, although nests may be grouped together in wetlands (due to its polyandrous mating system) and it is occasionally observed in small parties or larger groups of up to 100 individuals during the non-breeding season1. The species is crepuscular2 and roosts in cover by day and night singly or in groups of up to 3 individuals3.
The species shows a preference for recently flooded areas in shallow lowland freshwater temporary or permanent wetlands4 in the tropics and subtropics, its patterns of habitat use being governed by the rains1. Suitable habitats include extensive swamps and marshes2, reedbeds, overgrown rice-fields1, inundated or waterlogged grassland and saltmarsh4, the muddy margins of pools, freshwater lakes with grassy islets, sewage pools, reservoirs, mudflats overgrown with marsh grass and mangroves1, and thickly vegetated banks of slow-flowing rivers3. It requires emergent vegetation in shallow water for nesting2 and occasionally forages on open grassland adjacent to wetlands1.
The species is omnivorous, its diet consisting of insects1 (e.g. crickets and grasshoppers)3, snails, earthworms, crustaceans and seeds1.
The nest is a shallow cup1 in a mound of vegetation2 on the ground1, concealed amongst thick emergent vegetation in shallow water2. Alternatively nests may be placed in more open environments such as on dense mat of floating water-weed1.

LC
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
<Population justification> Previous estimate of 36,000 - 1,000,000 (Wetlands International, 2006) revised, decreasing the population minimum by 5,000 individuals representing the newly-split species R. australis.
<Trend justification> The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2006).

The Asian Waterbird Census (AWC) was initiated in 1987 and runs in parallel with other waterbird censuses carried out in Africa, Europe, Central and West Asia and Latin America under the umbrella of the International Waterbird Census (IWC), which is organised by Wetlands International.
The AWC takes place annually, during the second and third weeks of January, and is carried out by volunteers interested in collecting information on waterbirds and wetlands as a basis for contributing to their conservation.
