This very rare Falcon is a large form of F. rufigularis, and but few specimens are to 

 be found in Museums. In 1860 we secured from Mr. Meany, of Guatemala, a fine 

 adult female, which, he obtained in Vera Paz ; this specimen, which is figured on our 

 Plate, is the only one known to us from that country. In Costa Rica it is apparently 

 of more frequent occurrence, having been procured by several collectors. 



Nothing is known of its habits or breeding.
