Overview
The Pink-headed Duck is a distinctive waterfowl species characterized by its rose-pink head and neck, contrasting with a dark brown body and lighter underparts. Males display more vibrant coloration than females, with a pronounced pink hue extending from the bill to the upper neck. This medium-sized duck measured approximately 60 centimeters in length and inhabited shallow wetlands, where it fed on aquatic vegetation, seeds, and small invertebrates.
The species played a role in wetland ecosystems as both herbivore and prey for larger predators.
Historically, the Pink-headed Duck occurred across the Gangetic plains and Brahmaputra valley, ranging through northeastern India, Bangladesh, northern Myanmar, and southern Nepal. It preferred tall grassland pools, oxbow lakes, and swampy areas within or adjacent to forest regions, particularly favoring secluded wetlands with dense vegetation cover.
The species faces multiple ongoing threats that have driven it to near-extinction. Hunting pressure has been significant, with the duck targeted for food and sport. Habitat conversion to agricultural cropland has eliminated crucial wetland areas, while logging activities have degraded surrounding forest ecosystems. Invasive species and diseases have further compromised remaining populations and habitats.
Conservation efforts remain limited due to uncertainty about surviving populations. Sporadic surveys continue across the historical range, though no confirmed sightings have occurred in recent decades. Wetland protection initiatives in the region may benefit the species if populations persist.
The Pink-headed Duck's current outlook remains critically uncertain, with many experts considering it possibly extinct despite its Critically Endangered classification.
The Pink-headed Duck faces multiple ongoing threats including hunting and trapping by people, competition and disease from non-native species that have been introduced to its habitat, conversion of its wetland areas to farmland for growing crops, and the cutting down of forests for timber. These combined pressures have severely impacted the species' ability to survive in its natural environment. All of these threats are currently ongoing with no clear indication of improvement.
