Chaetocercus bombus has historically been recorded from central
Peru (seven departments from La Libertad and Huánaco in the south), on both slopes of the Andes north through Andean and west-central lowland
Ecuador (14 provinces) to south-west
Colombia (Nariño), where it was recently discovered and is thought to be seasonal (Salaman and Mazariegos 1998). It was once common, but has declined significantly, and very few have been recorded in recent years
(Fjeldså and Krabbe 1990), although several were reported recently from northern Peru (T. Marks
in litt. 2003). During the 1990s, it was considered uncommon in Machalilla National Park, Manabí, Ecuador (Parker and Carr 1992), and common in the newly established Loma Alta Ecological Reserve (7.5 km
2), Guayas, Ecuador (Becker and López Lanús 1997), but recent reports relate to single individuals (e.g. at least one at Dos Mangas Communal Reserve, Guayas in 2005 [Ágreda 2007]) and it is not known to be present regularly or in large numbers anywhere in the country (Gurney 2006).
