This species has an extensive but narrow and altitudinally restricted linear distribution on the coastal ranges of north-central
Venezuela (Carabobo and Aragua) and north-eastern
Colombia (Santa Marta Mountains), and from the subtropical slopes of the Andes from Venezuela (Mérida and Perijá Mountains) through Colombia,
Ecuador and
Peru to west-central
Bolivia and north-western
Argentina (Fjeldså and Krabbe 1990, Thiollay 1994, Roesler
et al. 2008). It is thought to be rare and patchily distributed but its status is very poorly known (Thiollay 1994
, Ferguson-Lees and Christie 2001). The total population is precautionarily estimated to include fewer than 1,000 mature individuals (Ferguson-Lees and Christie 2001, C. Márquez
in litt. 2014), with no more than 250 mature individuals in each sub-population.
