157. Ostinops Montezuma, Less. 



Very common at San Carlos and Naranjo, February. The sight 

 of their nests hanging close together at the extremity of the branches 

 on the trees is very peculiar. They select the highest trees left where 

 the forest has been cleared ; so that they cannot escape detection. I 

 have seen as many as thirty nests in one single tree. They make a 

 fearful noise when they come and go out of their nests.

One specimen, from San Jose, March. Killed on the bushes 

 forming the edges of coffee-plantations. I have seen many other 

 specimens.
