38 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



Range. — Pacific slope from the eastern side of the Azuero 

 Peninsula east through the lowlands to eastern Darien ; Caribbean 

 slope from the lower Rio Chagres Valley through eastern Colon to 

 extreme western Comarca de San Bias (Puerto Obaldia) ; inter- 

 grades with A', g. costaricensis in western Colon. 



In the original description Lawrence stated merely that his type 

 specimen, collected by McLeannan, came from the "Isthmus of 

 Panama." This collector, who worked near the Frijoles and Lion 

 Hill stations, is known to have taken birds mainly on the Caribbean 

 slope near the place last mentioned. The type locality is here 

 designated as near Gatun. since Lion Hill, less than 4 miles distant, 

 is now submerged in Gatun Lake. The type specimen, in the Ameri- 

 can Museum of Natural History, does not have the sex indicated, 

 but from its size (wing 91.4 mm.) appears to be a female. 



On Barro Colorado Island, Chapman (Life in an Air Castle, 1938, 

 pp. 35-36) found a nest on April 14, 1937, beneath the elevated 

 floor of one of the buildings. The birds carried in over 7000 

 small fragments of bark and dead wood for nesting material, and 

 in a slight depression laid two white eggs. Another nest was found 

 in May 1935 in a hole in a papaya. Goldman records a male taken 

 May 30, 1911, near Portobelo, as breeding. On March 4, 1968, at La 

 Jagua, Eisenmann and Ridgely recorded a mated pair at a nesting hole 

 in a dead tree. 



Beyond Darien this race ranges widely in northern Colombia from 

 northern Choco east through the Sinu, Cauca, and Magdalena valleys 

 to western Guajira.
