This is a very common bird throughout the greater portion of Costa 

 Rica, although very rare below 1,000 feet on the Caribbean lowlands. On 

 the Pacific side it is commoner lower down, but seems to be entirely absent 

 from the Terraba Valley, being found only in Nicoya and Guanacaste 

 in small numbers. 



In the plateau region it is common in all of the cultivated districts, 

 abounding in the pastures, coffee-plantations, and scrubby woodland.

 collector, following him about and screaming so loudly that it frightens 

 away all other birds. It is usually seen in small flocks.
