These specimens have somewhat more black on the head than 

 those m a series from the lower Orinoco, but agree with them in 

 other respects. They thus show no approach to the green-backed 

 T. c. coloreum of southern Brazil. The white-throated T. sduteri, is 

 evidently confined to the Pacific coast region.

An adult female has the head and throat somewhat paler than in 

 Colombian specimens, but aside from this I am unable to find any 

 difference between it and a Colombian series.
