-The Pink-headed Duck (Netta caryophyllacea) is (or was) a large diving duck. The 60 cm long Pink-headed Duck is unmistakable. It is long-bodied and long-necked, with a slightly tufted head in the male, and a peculiar, stiff-necked posture. The adult male has a chocolate-coloured body and a deep pink head and hindneck. The female and juvenile are duller, appearing much like a dark female Red-crested Pochard with a pinkish tinge to the head. Confusion with male Red-crested Pochards stems mainly from observations of swimming birds, as the latter species also has a conspicuous red head (although the color is actually very different from the Pink-headed Duck). Spot-billed Ducks, on the other hand, look similar to female Pink-headed Ducks when in flight and seen from a distance, and if seen from behind, they could be mistaken for males too. The upper side of the wing is distinguishing, with dark green secondaries (speculum) and prominent white tertiaries in the Spot-billed Duck and a pinkish-beige speculum, much lighter than its surroundings, in the Pink-headed Duck. If the upper part of the wings cannot be reliably seen, they are all but indistinguishable except for expert observers in good visibility conditions.+

Rhodonessa caryophyllacea

Contents

[edit] Identification

60. Long-bodied and long-necked, with a slightly tufted head in the male, chocolate-coloured body and a deep pink head and hindneck. The female and juvenile are duller.

[edit] Distribution

Formerly found in Bangladesh, India and possibly Nepal and Myanmar. Last reliable sighting in 1949. However, reports from Myanmar and other parts of the Brahmaputra River system continue. This may be confusions with Red-crested Pochard or White-winged Duck, but there is still some hope that this species may still survive.

[edit] Taxonomy

Recent phylogenetic analysis suggest that this species was closely related to the Red-crested Pochard and may have belonged to the same genus Netta.

[edit] Habitat

Lowland marshes and pools in tall-grass jungle.

[edit] Behaviour

The nest is built amongst grass.

Diet includes aquatic plants.
