Netta peposaca
The Rosy-billed Pochard, *Netta peposaca*, is a strikingly handsome waterfowl species native to southern South America, renowned for the male's distinctive appearance. Adult males boast a glossy black body, a vibrant rosy-red bill with a knob-like base, bright red eyes, and a prominent white flank patch visible in flight or when resting, contrasting sharply with their dark plumage. They typically measure 53-57 cm (21-22 in) in length, have a wingspan of approximately 75-80 cm (30-31 in), and ...
Rosy-billed Pochards primarily inhabit freshwater wetlands, including large permanent lakes, ponds, slow-moving rivers, and marshes, particularly those with abundant emergent and submerged vegetation. They are typically found in lowland areas, rarely exceeding 1000 meters in elevation.
Their diet primarily consists of aquatic vegetation, including seeds, leaves, and stems of grasses and aquatic plants, supplemented by a significant intake of aquatic invertebrates such as insects, crustaceans, and mollusks. They forage by both dabbling and shallow diving.
Active primarily during the day, Rosy-billed Pochards spend their non-breeding seasons in large, gregarious flocks, often forming dense rafts on open water for communal roosting. Foraging involves a combination of dabbling and shallow dives, often head-dipping to reach submerged vegetation and in...
The Rosy-billed Pochard is endemic to South America, primarily inhabiting the temperate and subtropical regions of the continent. Its core breeding range extends across Argentina, Uruguay, Paraguay, southern Brazil (notably Rio Grande do Sul), and eastern Bolivia. During the austral winter, many ...
Least Concern
- The Rosy-billed Pochard is the only member of the genus *Netta* found in the Americas; its closest relatives are Old World species like the Red-crested Pochard. - Despite its classification as a 'pochard' (typically diving ducks), it frequently employs dabbling techniques, often head-dipping to...
