Range Description

Tachyeres leucocephalus was previously considered to be restricted to the south coast of Chubut province, Argentina(Madge and Burn 1988, Carboneras 1992a). It is now known to have a larger range, with occasional sightings along the coastline from the Valds Peninsula to the Beagle Channel in Tierra del Fuego (Imberti 2003, M. Pearman in litt. 2003), but its distribution is restricted to approximately 700 km of coastline (Agero et al. 2011). The population has been estimated to not exceed 5,000 birds (S. Imberti in litt. 2003), and surveys along the coast of Chubut province from 2006-2008 gave a total estimate of 3,400-3,700 mature individuals (G. Borboroglu in litt. 2008, Agero et al. 2011), with key populations at Baha San Gregorio, Baha Melo and Caleta Malaspina, all located at northern San Jorge Gulf. It appears to occur at very low densities throughout its range, and is inferred to be declining (Agero et al. 2011).
