This species has an exceptionally wide range in Colombia occurring in 

 every fauna of the Tropical Zone from the Pacific coast to the eastern plains 

 though it has not been taken in the Cauca Valley. As Hellmayr has said 

 in Pacific coast specimens the head averages slightly duller, but they can be 

 exactly matched by others from farther east. This constancy of color in 

 birds from regions so widely separated and so different in climatic conditions, 

 renders all the more surprising the fact that in western Ecuador a distinct 

 form {T. p. molarvata Berl.) of this bird should be found.
