Pink-headed Duck - Illustration
The Pink-headed Duck was always considered rare, but it has not been conclusively seen in the wild since 1949 in India and is known from Myanmar from only two individuals. Unconfirmed reports of Pink-headed Duck sightings in 2006 spurred conservationists to continue to look for it and to try to capture the first photos of a live bird, unsuccessfully. In addition to the deep pink head and neck found on male ducks, these birds lay spherical eggs and likely live in tall, thick elephant grasslands, swamps and floodplains. ...

CR Pink-headed Duck Rhodonessa caryophyllacea
... Threats
Its decline likely resulted from habitat loss. Clearance of forest and conversion of wetlands for agricultural land has destroyed much of its habitat, and the invasive alien species water hyacinth Eichhornia crassipes may have contributed to its decline by altering wetland habitats to the detriment of this species (J. Eames in litt. 2006). Additionally, it suffered year-round persecution during the late 19th and early 20th centuries, when hunting levels in India were high ...
https://en.wikipedia.org/wiki/Pink-headed_duck
The pink-headed duck (Rhodonessa caryophyllacea) is a large diving duck that was once found in parts of the Gangetic plains of India, Bangladesh and in the riverine swamps of Myanmar but feared extinct since the 1950s. Numerous searches have failed to provide any proof of continued existence. It has been suggested that it may exist in the inaccessible swamp regions of northern Myanmar and some sight reports from that region have led to its status being declared as "Critically Endangered" rather than extinct.[1][3] The genus placement has been disputed and while some have suggested that it is close to the red-crested pochard (Netta rufina), others have placed it in a separate genus of its own. It is unique in the pink colouration of the head combined with a dark body. A prominent wing patch and the long slender neck are features shared with the common Indian spot-billed duck. The eggs have also been held as particularly peculiar in being nearly spherical. ...

El pato cabecirrosa, pato de cabeza rosada o pato cabeza rosada (Rhodonessa caryophyllacea) 2 es una especie de ave anseriforme de la familia Anatidae que habitaba en el subcontinente indio. Está extinta o en grave peligro de extinción, ya que su último avistamiento seguro fue en 1949, aunque puede que existan pequeñas poblaciones en el norte de Birmania.
Un análisis filogenético mostró que estaba estrechamente emparentado con el pato colorado europeo (Netta rufina), por lo que en ocasiones es incluido en el mismo género que este.3

... El exótico pato de cabeza rosada (Rhodonessa caryophyllacea), cuyo plumaje de color de rosa lo diferenció de cualquier otra especie de aves acuáticas, fue visto por última vez en la naturaleza en la India en 1949. Los científicos nunca descubrieron qué pigmento era responsable de su coloración única y vívida -hasta ahora. Un próximo estudio en The Auk: Ornithological Advances confirma que los carotenoides, pigmentos que brindan los colores brillantes de aves como cardenales y flamencos, pero que son mucho más raros entre los gamebirds, fueron los responsables del rasgo homónimo del extinto Pato de cabeza rosada. ...
