A common winter resident over the higher parts of the country and 

 the region of the plains of northwestern and southwestern Costa Rica. 

 I never saw it on the Caribbean lowlands, for the reason, I suppose, 

 that there are few or no suitable conditions for it. I saw a pair in 

 October flying about the marsh at El Alto (Ochomogo).

Dr. Richmond informs me that the now accepted name for this 

 species is that here used, that Sparverius semitorquatus Vieillot, does 

 not refer to this bird, nor does melanoleucus. 



This Micrastur seems to be sparingly distributed over nearly the 

 whole of Costa Rica, up to 6,000 or 7,000 feet. In spite of the fact 

 that it has such a wide range it is not a common bird anywhere, while 

 its habitat renders it more difficult to find and collect than most hawks. 

 It keeps entirely within the forest, and like all of the genus is to be 

 found low down.
