Field notes

Appearance

This duck is highly distinctive with a long neck, long legs, and reddish bill. Plumage features a chestnut head and neck, black belly, white eye-ring, and bright red legs; sexes are similar in appearance.

Size and weight

Adults typically weigh 0.5–0.7 kg (females slightly lighter) and measure 45–53 cm in body length.

Habitat

Black-bellied whistling-ducks inhabit freshwater and brackish wetlands, marshes, ponds, and shallow lakes with emergent vegetation. They favour lowland areas from sea level to moderate elevations, preferring open water with nearby trees or shrubs for roosting.

Distribution

Found from the southwestern United States through Central America and into South America, with populations expanding northward. They occupy permanent and semi-permanent freshwater wetlands in warm lowland regions.

Diet

Black-bellied whistling-ducks feed primarily on aquatic vegetation, seeds, and invertebrates, with preference shifting toward seeds and plant matter during dry seasons.

Behaviour

Highly social and vocal ducks, most active at dawn and dusk but also feed during daylight and night. They roost communally in trees or on water and are often seen in small flocks; pairs are monogamous.

Hunting tips

Look for their distinctive three-note whistling calls, droppings around shallow water margins, and clustered roosting sites in trees at dawn or dusk. Approach shallow wetlands quietly during low-light periods, using vegetation or terrain contours for concealment. These ducks are wary and will flush readily; glass open water edges before entering to locate feeding birds.
