AMERICA generally, from Colombia, Trinidad, and Guiana to Paraguay. 
All specimens from the lower Rio Grande Valley and North-eastern Mexico examined 
by us have the tail of the ordinary hepatic type as seen in southern examples, but the 
head and back are not nearly so rufous nor are they so grey as southern birds in that 
phase. In the State of Vera Cruz dark-tailed birds begin to appear and are found 
everywhere to the southward of that State. 
Dr. Sharpe separated the Mexican and Central American bird under the title of 
G. ridgwayi, keeping the South-American bird and that of the island of Trinidad 
distinct subspecies, calling them G. ferox (Vieill.) and G. phalenoides (Daud.) 
respectively. But admitting, as everyone must, a large amount of variation between 
individuals of this Owl, we are not able, with the very large series of specimens before 
us, to select any characters by which these races can be satisfactorily distinguished. The 
range would appear to be quite unbroken from the Rio Grande of Texas to Paraguay. 
Daudin’s name G. phalenoides, bestowed upon the bird of the island of Trinidad in 
1800, is the oldest !.
