Mr. G. C. Taylor met what he presumed to be this Hawk in great abun- 

 dance at Comayagua, Honduras, in January. He saw a pair making their 

 nest on the top of a lofty cotton-tree. 



Captain Bendire found this species not uncommon and breeding in" the 

 vicinity of Tucson, in Arizona. He found two nests, one of which was 

 taken June 6, the other a few days later. They were very slightly built

 by 1.60 inches in breadth.
