Description
Size: 80 cm

Common winter visitor to north India. This bird is found in large wetlands.

Identification: It is mainly brown with a gray rump and white tail. Flesh pink colored bill is diagnostic.

Habitat: Breeding- During the breeding season the species inhabits wetlands surrounded by fringing vegetation in open grassland, sedge or heather moorland, arctic tundra, steppe or semi-desert from sea-level up to 2,300 m. It nests near streams, saltmarshes, river flood-plains, reedy marshes, grassy bogs, damp meadows, reed-lined freshwater lakes and estuaries close to potential feeding sites such as meadows, grasslands, stubble fields and newly sown cereal fields. It requires isolated islands in lakes or on along the coast out of reach of land predators for nesting. In the autumn (before migration) the species also frequents agricultural land (e.g. sugar-beet, maize and cereal fields). Non-breeding In the winter the species inhabits lowland farmland in open country, swamps, lakes, reservoirs, coastal lagoons and estuaries.

Breeding season- May or April. Nest- The nest is a shallow construction of plant matter placed among reedbeds, on the ground , in or at the base of trees, under bushes or in sheltered hollows on isolated wooded islands on lakes or along coasts, as well as on rafts of vegetation in rivers. Although the species is only semi-colonial, nests may be concentrated within a small area (e.g. placed 11 m apart on small islands).

Economic Importance and Threats
Threats:  Anthropogenic
(This species is threatened by considerable hunting pressures across much of its range and is susceptible to poisoning from lead shot ingestion. It is also persecuted by farmers as it can cause considerable crop damage. The destruction and degradation of wetland habitats due to drainage, conversion to agriculture, petroleum pollution, peat-extraction, changing wetland management practices (e.g. decreased grazing and mowing in meadows leading to scrub over-growth) and the burning and mowing of reeds is also a threat, especially in breeding areas.)
Threats:  Natural threats
(The species is susceptible to avian influenza so may be threatened by future outbreaks of the virus )
Importance:  Dangers
(It can cause considerable crop damage)

Ecology
Habitat:  Estuarine, Coastal
