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.
