The only, until then, known population, corresponding to Lake Los Escarchados (some 50 km East Southeast of Lake Argentino, Province of Santa Cruz), has been estimated in 140 to 150 individuals. It is known, though, that the number varies for these grebes migrate in winter, as the lake's surface freezes. Two additional small groups have been found in neighbouring lakes, one of them breeding (trhee pairs). 1983-06 PDF Español info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by-nc-sa/2.5/ar https://hdl.handle.net/20.500.12110/hornero_v012_n01extra_p256
