The present species is one of the rarest of the Central American 

 hawks, but three specimens being known from Central America pre- 

 vious to the taking of those recorded above, two from Panama and one 

 from Greytown, Nicaragua (A. Alfaro), the latter being in the Museo 

 Nacional de Costa Rica. This specimen was reported by Mr. Cherrie 

 (Proc. U. S. Nat. Mus. , XIV, 1891, 537). It seems to be restricted 

 to the northeastern parts of Costa Rica, for although I always hunted 

 for it in other places I never saw it outside of that region. It is an 

 inhabitant of the dense forest, with habits very similar to those of 

 Micrastnr interstes. The male taken at El Hogar in March, 1907, 

 was eating a freshly killed ant-thrush (^Ramphoccemts semitorquatits) , 

 and allowed me to approach within thirty feet of it without showing 

 signs of fright or ceasing to feed on its prey.
