Habitat

These teal species inhabit water bodies with abundant emergent and submergent vegetation such as ponds, streams, marshes, swamps, coastal wetlands and flooded grasslands.

Feeding habits

The marbled teal species are omnivorous and feed on aquatic plants, seeds, shoots, roots, tubers, aquatic invertebrates, molluscs and crustaceans.

Breeding

The breeding season is from mid April to late June. The marbled teal species nest on the ground, near the water edge under vegetative cover. The nest may contain 7 to 10 cream eggs.

Distribution

Movement Patterns

These teal species are partially migratory. Breeding populations occurring the northern parts move southwards for wintering. These teals disperse widely for feeding grounds after breeding.

Status and conservation

The global population is estimated to be 50,000 to 55,000 individual birds. The fragmentation of the population, habitat degradation and hunting are the main conservation concerns.
