This seems one of the most common and widely distributed species 

 of birds in Cisandean South America. There is some variation in 

 the length and thickuess of the bill, and amount of white on the 

 wings. Prince Bonaparte has nanied a Yenezuelan bird exhibiting 

 some differences in these respects, Tachyphonus beauperthuii, but I 

 have not recognized that species as disrinct, because I have observed 

 such differences in specimens brought from the šame locality.
