Char, subsp. — Similar to H. c. cachinnans (Linn.) but smaller and more richly 

 colored; the upperparts and wings externally darker (dark sepia); the underparts, 

 crown, nape, upper tail-coverts and under wing-coverts nearly uniform cinnamon- 

 buff, instead of white washed with light buff; the crown more streaked, the lower 

 wing-coverts more spotted. 



Inhabits the Tropical Zone of the Pacific Coast from Panama southward 

 to Ecuador.

Of general distribution from sea-level up to at least 10,000 feet alti- 

 tude. It occurs singly and is also found in companies. Mr. Outram Bangs 

 calls my attention to the fact that South American specimens (Costa 

 Rica and southward) of this species differ from North American specimens 

 in having the scapulars, and to a lesser extent interscapulars, rich bottle- 

 green instead of dark purplish maroon.
