Range Description

Grallaria alleni is known from the west slope of the Central Andes in Colombia, and both Andean slopes in north Ecuador. The nominate subspecies was collected near Salento, Quindo, in 1911, and has been recorded in nearby Ucumar Regional Park, Risaralda, Colombia, several times during 1994-2000 (P. G. W. Salaman in litt. 1999, C. Downing verbally 2000, Krabbe and Coopmans 2000). The subspecies andaquiensis was described from a specimen taken on the west slope of the southern East Andes in Cueva de los Gucharos National Park, Huila, Colombia, in 1971 and, during the 1990s, has been found at single sites in Napo and Cotopaxi (Freile and Chaves 2004) and at four sites in Pichincha, Ecuador (J. Lyons in litt. 1998, N. Krabbe in litt. 1998, Krabbe and Coopmans 2000). Suitable habitat covers an estimated 3,500 km2 in Ecuador (Krabbe et al. 1998), but it is unclear how much of this is occupied. Recent surveys in Ecuador found at least 4-6 territories along three 1 km transects (J. F. Freile in litt. 2004, 2008). There are several new localities where the species has been recorded in Ecuador, mostly concentrated on the western slopes of Pichincha province (J. F. Freile in litt. 2004, 2008), and the species has recently been discovered to be much commoner and more extensively distributed in Colombia than previously thought (F. G. Stiles in litt. 2005). The paucity of earlier records is related to the fact that its vocalisations were unknown until recently.
