Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Babarskas, M., Benstead, P., Capper, D., Pilgrim, J., Sharpe, C J, Symes, A.
Justification:
This species has a moderately small global population which may be declining owing to habitat degradation and hunting. It is consequently classified as Near Threatened.

Geographic Range [top]

Range Description: Fulica cornuta is known from a few high altitude Andean lakes in south-west Bolivia (Oruro in 1903, Potosí), north Chile (Tarapacá, Antofagasta, Atacama), and north-west Argentina (Jujuy, Salta, Catamarca in 1918, Tucumán, San Juan) (Haene and Montañez 1996). Large concentrations have been recorded only occasionally, most notably 8,988 in the Vilama and Pululos area of Argentina in October 1995 (TWSG News 9 1996: 34-39), and 2,800 birds on Laguna Pelada, Bolivia, in November 1989 (Cabot and Serrano 1982). It normally occurs at low densities, with 1-10 nesting pairs at most sites, and up to 70-90 at a few (Taylor 1996, TWSG News 9 1996: 34-39). The Chilean population is estimated at 620 birds (Glade 1988), and Bolivia seems to hold a healthy population (Rocha and Quiroga 1996). The global population is likely to be in the range of 10,000-19,999 individuals. There is no definite evidence of a recent decline (Taylor 1996), but local populations are believed to fluctuate greatly between periods of drought and inundation.

Population [top]

Population: A total of 8,988 individuals were counted in Argentina in 1995, 2,800 in Bolivia in 1982 and 620 are estimated in Chile. The total is probabaly in the range of 10,000-19,999 individuals, and probably fluctuates greatly. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits high altitude Andean lakes, with dense submerged aquatic plants, primarily at 3,000-5,200 m but as low as 2,000 m in harsh weather.

Systems: Freshwater

Threats [top]

Major Threat(s): Its fresh and brackish lakes are susceptible to contamination and vegetation trampling by cattle, and water is pumped from some to coastal towns and mines. It also suffers from hunting, egg-harvesting, and some predation by Andean Gull Larus serranus.
