SEPT., 1910. BIRDS FROM COSTA RICA FERRY. 279 



Chlorospingus regionalis Bangs. 



1 8 specimens. Coliblanco 12 d\ 6 9. 



In company with C. pileatus and much like it in habits. 



Chlorospingus pileatus Salv. 



26 specimens. Coliblanco n c?, i 9 ; Vol. de Turrialba 9 o 1 , 5 9 . 



The most abundant bird about Coliblanco, and nearly as common 

 at base of Ash-cone. They are ubiquitous, scarcely a bird haunt 

 seems without them. Shrubbery and vine-covered trees are their 

 favorite places. 



Chlorospingus olivaceiceps Underwood. 

 2 specimens. Guayabo 2 cT. 



Icteridee. 



Zarhynchus wagleri (Gray}. 



3 specimens. Turrialba Station i 9 ; Guayabo cT ; Coliblanco 9 . 

 Common at Turrialba Station but not elsewhere. 



Gymnostinops montezuma (Less.}. 



9 specimens. Guayabo 4 cT, 4 9 , i sex?. 



Abundant at Guayabo but not positively identified elsewhere. 

 No nesting site was discovered and dissection showed the birds were 

 not breeding. They roved about in large, noisy bands. Their great 

 variety of notes is absolutely indescribable. Screeches, grunts, 

 groans and whistles all can be recognized in the discord emanating 

 from a flock. This species and the preceding possess a peculiar 

 strong, musky odor. 



Icterus prosthemelas (Strickland). 



i specimen. Guayabo d\ 



This specimen was taken in a vine-covered stub standing in the 

 heavy forest. 



Icterus gal hula (Linn.}. 



3 specimens. Guayabo cT, moulting into the fully adult plumage; 

 C? immature; 9 in winter plumage. Dates: January 16, February 

 5, February 5.
