Range DescriptionAratinga brevipes is endemic to Socorro in the Revillagigedo Islands, Mexico. The population was estimated at 400-500 birds within c.35 km2 of suitable habitat in 1991. Numbers were considered stable and did not decline subsequently in the early 1990s (RodrÃguez-Estrella 1995, RodrÃguez-Estrella et al. 1996). However, there may have been some contraction in range since c.1960. Surveys from 2006 and 2007 estimated a population of c.300 individuals, suggesting a population decline from previous population estimates (J. E. MartÃnez-GÃ³mez in litt. 2007).
