Resident. Known only from lowland forest in southeastern coastal 

 Darien and adjacent northwestern Colombia, both on the Pacific slope 

 and the Gulf of Uruba, Choco. The type was brought to Oustalet at 

 the Paris Museum in 1877 by Dr. C. Viguier (Salvin and Godman, 

 Biol. Centr.-Amer., Aves, vol. 1, p. 246) with "coast Gulf of Darien" 

 as the locality. In April 1946, Watson Perrygo and I collected a male 

 and female in the forest at El Brazo, near Jaque. These are the only 

 other specimens I know of from Panama. There is a sight report of a 

 male seen near El Real, Darien, on January 13, 1978, by Howard P. 

 Brokaw and Nicholas Brokaw. Nothing is recorded as to the life his- 

 tory of this species.
