This species is classified as Near Threatened because it is continuing to undergo a moderately rapid population reduction owing to hunting pressure and habitat loss. It is still locally common in certain areas and, with proper protection, would be much more abundant over its wide range.

Geographic Range [top]

Range Description: Neochen jubata remains relatively widespread in South America east of the Andes, from east Colombia and Venezuela (where taken together there are probably 5,000-10,000 individuals [T. McNish in litt. 2007]), Ecuador (previously thought to just be a vagrant (Ridgely et al. 1998), but a small population of 20-30 now known from the Rio Pastaza area), Guyana, Suriname (no recent records and may never have been more than a vagrant [K. Kreise in litt. 2004]), south through Amazonian Brazil (where there are thought to be 2,000-4,000 individuals in the Cantão and Bananal Island region alone [R. Pinheiro in litt. 2007]), extreme east Peru (relatively common [Clements in prep.]), Bolivia (perhaps a few thousand pairs [J. Tobias in litt. 2007]) and west Paraguay (two records, in 1990 and 1992 [Hayes 1995]) to extreme north-west Argentina (either very scarce there now or just a vagrant) (Carboneras 1992a),. Clear declines have been noted in Brazil, Colombia, Ecuador, Peru and Argentina (Callaghan in prep.), and although the population was once estimated at c.25,000-100,000 individuals (P. Canevari in litt. 1993) it is now more likely to be 10,000-25,000 (K. Kreise in litt. 2004). Its strongholds appear to be the extensive, sparsely inhabited area of lakes, marshland and seasonally flooded savannas in north Beni, Bolivia, where flocks of up to 250 were observed in the early 1980s (Scott and Carbonell 1986, Ridgely et al. 1998), the Isla Bananal, Brazil (C. Yamashita verbally 2000) and the Colombian and Venezuelan llanos. It is becoming increasing localised over much of its range and is now scarce, except in remote or protected areas (Carboneras 1992a).

Population [top]

Population: The global population has been estimated to number 10,000-25,000 mature individuals based on the result of discussions on BirdLife's Globally Threatened Birds Forum.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits forest-covered banks of tropical rivers and damp clearings, wet savannas and muddy and sandy margins of large freshwater wetlands, from lowlands to 500 m (Carboneras 1992a), occasionally to 2,600 m (Hilty and Brown 1986).

Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The current decline is attributed to heavy and continuing hunting pressure (Carboneras 1992a); although availability of foraging habitat may limit numbers locally, the abundance of the species on certain private reserves where it is well protected indicate that hunting is the primary reason for its decline. In Venezuela, conversion of former private reserves for rice production may threaten previously well-protected populations of the species (C. J. Sharpe in litt. 2010).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
It occurs in a number of private and public protected areas.

Conservation Actions Proposed
Continue to monitor population trends through regular, coordinated surveys. Monitor levels of hunting pressure. Conduct awareness campaigns to discourage hunting and regulate the number of birds taken. Protect significant areas of suitable forest and wetland habitat in a network of public and private reserves.
