land and scattering trees in pastures, as well as the heavy forest, and 

 is almost always seen in small flocks. It is not a shy bird by any 

 means, permitting itself to be closely approached, and the entire flock 

 will often remain in a tree after one of its members has been shot. 

 The note is very peculiar, not unmusical, but with an odd grating 

 or rasping sound. Nutting states that he shot one with a large beetle 

 in its mouth, but I have never found anything but fruit and berries in 

 the crop,. It is supposed to breed in holes in trees, but I have never 



seen the nest.

This species has been recorded by early writers and collectors from 

 San Jose, Angostura, and San Carlos, the two latter localities on the 

 Caribbean slope at a rather low altitude. I have never taken it or 

 seen a specimen taken on the Caribbean slope, and I feel quite sure 

 that early writers must have confused the two birds, or else they were 

 not labelled properly by the collectors. 



From my own experience and from the published records for the 

 species, I am inclined to restrict its range exclusively to the Pacific 

 slope and from the Gulf of Nicoya southward. It very probably does 

 get up on the plateau region in small numbers, but the region where 

 it is most commonly found is between sea-level and 1,500 feet. Its 

 habits are precisely the same as those of the preceding species.
