never saw it in the same region, during the year I was there. Zeledon 

 also records one from near Juan Vinas (Birris). Taking these records 

 into consideration, the bird is evidently found over the whole of the 

 lower portion of both slopes, up to 3,000 feet, but is not common 

 anywhere. The specimens secured at Boruca (two) were taken in 

 the forest in one of the deep valleys so common in that region.

This is one of the rare hawks, not only of Costa Rica, but of the 

 whole of Central America. Its habits are quite similar to the mem- 

 bers of the genus Falco, as far as I was able to observe, and from 

 what Mr. Lankester told me. A pair was seen at Cuabre, but the 

 male escaped.

Found on both the Pacific and Caribbean slopes, usually below 

 2,000 feet, but much more commonly on the Pacific. Its habits are 

 typical of the genus, perching on a dead stub or exposed branch, and 

 darting out after its quarry.
