however (as for instance Nos. 15,268, Field Museum of Natural 

 History, Achotal, Vera Cruz, 37,053, Field Museum of Natural

 Cruz, and 106,321, U. S. National Museum, Yucatan), is absolutely 

 indistinguishable from typical rufipennis, but the Mexican series as a 

 whole is obviously different. Guatemala birds seem referable to the 

 southern form, as well as those from Honduras and Nicaragua, while 

 specimens from Costa Rica and Panama are exactly like those from 

 Colombia. On the other hand, some of the southern birds are almost 

 pale enough to be referred to C. r. eluta; they are, however, apparently 

 all immature birds. Everything considered, this is probably as good 

 a subspecies as many others which have been admitted to recognition.
