Field notes

Appearance

Males are unmistakable with a bright blue bill, white face mask, and dark chestnut body plumage. Females are drab brown with a pale facial patch and lack the pronounced mask; both sexes are small, compact dabbling ducks.

Size and weight

Males 20–23 cm, 340–370 g; females 19–21 cm, 310–340 g.

Habitat

Masked ducks inhabit shallow freshwater marshes, ponds, and lagoons with dense emergent vegetation such as reeds and cattails. They prefer lowland wetlands from sea level to moderate elevations.

Distribution

Found in the southwestern United States (rare vagrant), Mexico, Central America, and South America. Range is patchy and concentrated in shallow tropical and subtropical wetland systems.

Diet

Masked ducks feed primarily on aquatic plants, seeds, and invertebrates (especially insects and small crustaceans) gleaned from shallow water and marsh vegetation.

Behaviour

Highly secretive and crepuscular, they remain hidden in dense vegetation during the day and become active at dawn and dusk. They are strong fliers despite their small size and typically move in pairs or small family groups.

Hunting tips

Look for pairs or small groups in emergent vegetation at marsh edges during low-light periods. Approach slowly from downwind, using vegetation for cover. These ducks flush reluctantly and often dive; positioning near open water channels increases sighting opportunities.
