Distribution: Neotropical. Southwestern COLOMBIA (Cauca, Narino) and northwestern ECUADOR (Esmeraldas, Pichincha). more....

Subspecies: Monotypic.

Taxonomy: Formerly considered to be a race of M. gilvicollis (Meyer de Schauensee 1966, Stresemann and Amadon 1979), but treated as a full species by subsequent authors, including Sibley and Monroe (1990), Thiollay (1994), and Ridgely and Greenfield (2001). Published details on the basis for the latter treatment appear to be lacking.

Movements: Non-migratory (Bildstein 2006).

Habitat and Habits: Occurs in very wet lowlands, foothills, and premontane forests to 1,500 m in the Chocó region of Colombia and Ecuador, inhabiting the dark interior understory of humid primary forest (Bierregaard 1994, Salaman 1996).

Food and Feeding Behavior: Feeds on small, ground-dwelling animals, primarily small mammals, reptiles (especially Anolis lizards), and insects (Salaman 1996, Renjifo et al. 2002). Forages by using still or perch-hunting techniques in the dark forest understory and by running and hopping along the ground for short periods, occasionally alighting on low vegetation, e.g., the stilt roots of palm trees (Salaman 1996).

Breeding: Little is known, but nests are probably placed in tree cavities, as with other species in the genus, and breeding apparently takes place from January to July (Salaman 1996, Márquez et al. (2005). Salaman (op cit.) observed a prey exchange between members of a pair in December. more....

Conservation: Threatened mainly by habitat loss from deforestation, which has resulted in small, localized populations (Collar et al. 1992). Considered to be Endangered by Collar et al. (1994), but probably overlooked and not at grave risk, according to Ridgely and Greenfield (2001), who recommended Vulnerable status. Also categorized as Vulnerable by BirdLife International. more....
