Huge, wide-ranging vulture of the Andes, but also ranges into lowlands in southern Chile and Tierra del Fuego. Locally fairly common in Chile and adjacent Argentina, less numerous northward. Mainly seen as singles or pairs, sailing high over ridges, but tens can gather at roosts and to scavenge at carcasses. Size alone is diagnostic, but can be difficult to judge at a distance: note very long “fingers” at wingtips and white collar of adult. Adult also has diagnostic big white panels on upperwing, visible as birds bank. Immatures dark overall, becoming like adult in about 5 years.
