Habitat

These bird species inhabited lowlands, ponds, swamps and marshes with dense vegetation.

Feeding habits

These bird species might have fed on aquatic invertebrates, aquatic plants and vegetation.

Breeding

These duck species might have bred during summer months. The eggs of these birds were nearly spherical.

Distribution

The pink-headed duck was recorded to occur in eastern India, Bangladesh and northern Myanmar.

Movement Patterns

These duck species were resident birds in the areas of their distribution. They might have taken local movements in search of feed.

Status and conservation

The last recorded observation of pink-headed duck in wild was in 1949. Even the captive birds also existed around the same time. There were reports of unconfirmed sightings in Kachin State, Myanmar. Several surveys had been done to confirm its existence.

A. W. Tordoff et al. concluded in their study that "On balance, therefore, there are several reasons for believing that Pink-headed Duck may still persist in the lowlands of Kachin state and, perhaps, elsewhere in Myanmar." Hunting and habitat degradation were the main reasons in losing these bird species.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these duck species and has listed them as of "Critically Endangered".
