65. TANAGRA GLAUCOCALPA ( Cabanis). 

 GLAUCOUS BLUE-WINGED TANAGER. 



Native name ^' azulejo." 



These two taiiagers were equally abundant around EI Yalle. Their 

 favorite food was the ripe papaya fruit, but they also fed on mangoes 

 and copey seeds. 



[Between two Margarita exami)les and two froui kSabanilla, Colombia, 

 there is some color difference, the former being somewhat brighter blue 

 on breast and sides, and brighter in color generally, which, however, 

 may be due to their fresli condition, the othcir specimens being old 

 skins. The Margaritau exami)les are slightly larger, with more robust 

 (but not longer) bills. The differences in dimensions may be seen in the 

 following table :

67. VIREO CHIVI AGILIS ( Lichtenstein). 

 • AGILE VIREO. 



Common in the forests around El Valle. Its resemblance to a highly 

 colored red eyed vireo is strengthened by a portion of its song, which 

 is indistingaishable from that of our bird.
