the Rio Pucro in Darien I saw one capture a ringed kingfisher 

 (Megaceryle torquata) . 



In tlie original description of this race, through a typographical 

 error, the type, taken by Morton E. Peck, was listed as from 

 "Manatol" Lagoon. Stephen M. Russell informs me that Peck's 

 field notes state that the bird was collected "in the pine ridge near 

 Manatee Lagoon." Mr. Russell writes that tall rainforest and pine- 

 lands are found in this area. The former is the usual habitat of 

 this eagle. 



The subspecies vicarius is found from southern Mexico through 

 Central America and northern South America to western Ecuador. In 

 northern Colombia it ranges eastward across northern Antioquia to 

 western Guajira (to Riohacha). The typical subspecies, Spisaetus 

 ornatus ornatus (Daudin), which has the brown of the head and 

 neck brighter, more rufous, is found from eastern Colombia, east 

 of the eastern Andes, Venezuela, and Trinidad, south to Bolivia, 

 northern Argentina, and southern Brazil.
