Goldman secured his first specimen near Gatun as it sat in the 

 top of a tall tree eating an iguana. His second one circled over him 

 in early morning as he was ascending the Rio Indio, near Gatun, A 

 pair that I saw high in air above Barro Colorado Island were easily 

 identified by the long tail and dark color; and with binoculars I 

 could see the light markings on wing and tail. 



The present subspecies ranges from southeastern Mexico through 

 Central America to northern and western Brazil, The typical race, 

 Spisaetus tyr annus tyr annus (Wied), of eastern and southeastern 

 Brazil, according to Friedmann in his description of serus, is larger. 

 Another difference in the typical race is found in the lesser amount 

 of white on the under wing coverts, and in the narrower barring on 

 the legs, a character, however, that is variable, as immature individuals 

 of both subspecies have more white than the adults. 



When I came to Isla Coiba on January 6, 1956, Capitan Juan A. 

 Souza, Director of the Colonia Penal, showed me the partly decom- 

 posed feet of a hawk, kept as curiosities from a bird killed the week 

 before my arrival. These had the tarsi feathered, and appeared to 

 be blackish in color. Because of their condition I could detect no 

 markings, nor was I able to preserve them. I believed that they came 

 from a hawk eagle, probably from Spisaetus tyrannus, but of this I 

 was not certain. Some of the guards and convicts seemed to know this 

 group of hawks but I did not succeed in finding it.
