This wide-ranging Oriole is most common in the Subtropical Zone in 

 which it is found on both eastern and western slopes of the three ranges of 

 the Andes. Of our thirty-six specimens only two come from below 3000 feet, 

 a male from Chicoral and a female from Villavicencio. 



Specimens from the Cauca region average deeper in tone than those 

 from the Eastern Andes, but the difference is shght and wholly over-lapped 

 by individual variation.

(4511a) Icterus hondse Chapm. 



Icterus hondce Chapm., Bull. A. M. N. H., XXXIII, 1914, p. 191 (Honda, Col.). 



Char. sp. — Wings, tail, throat and capistrum black, unmarked as in Icterus 

 giravdi, orange areas as deeply colored as in Icterus auratus, with which it agrees in 

 size. 



This species is most closely related to giraudi, too closely one might 

 imagine for them both to breed in the same area. It is important to note 

 therefore that while we have found giraudi to be widely distributed in Co- 

 lombia, it is there a bird of the Subtropical Zone which we have rarely found 

 below an altitude of 3000 ft. Consequently if hondce be a representative of 

 giraudi their apparent distribution in the same area may be explained by 

 their occurrence in different zones, hondce inhabiting the Tropical, giraudi 

 the Subtropical Zone.
