straggler about San Jose, while Zeledon and Underwood have both 

 taken it there. 



They are particularly abundant in the northeastern part of the Carib- 

 bean lowlands, in what is known as the Santa Clara Valley, where they 

 are often seen flying about in large flocks, especially late in the after- 

 noon and evening.

The continental range of this species is quite large, extending from 

 Mexico down to northeastern Costa Rica, yet there is no appreciable 

 difference to be seen between Mexican and Costa Rican birds. I did 

 not meet with the species in southeastern Costa Rica, and consequently 

 believe it to be confined to the portion of the Caribbean lowlands 

 north of Port Limon. It is very abundant in the vicinity of Guacimo 

 and Guapiles, in fact the most abundant parrot on the Caribbean 

 slope, associating with the preceding species. They are very destruc- 

 tive to cornfields, attacking the grain just as the kernels begin to 

 harden and what they do not devour is spoilt by water entering the 



husk.
