FAMILY STRIGIDAE l6l 



male in the U. S. National Museum taken January 9, 1889. Another 

 female in the collections of the University of California at Los 

 Angeles was secured January 16, 1938, on the Rio Cricamola about 

 25 kilometers inland from the coast. 



As this owl has not been collected east of Code 2 sight records on 

 Barro Colorado Island, 1 in 1929 and the other in 1948, remain to be 

 verified. To the north this race ranges to southern Mexico. 



LOPHOSTRIX CRISTATA WEDELI Griscom 



Lophostrix cristata wedeli Griscom, Bull. Mus. Comp. Zool., vol. 72, January 

 1932, p. 326. (Perme, San Bias, Panama.) 



Characters. — General coloration darker, duller, with less white in 

 the scapular region; superciliary streak and the feather horns more 

 extensively white, and thus more prominent ; horns longer. 



Measurements. — Males (11 from Panama and Colombia), wing 

 283-306 (294.9), tail 168-189 (177.0), oilmen from cere 18.5-20.8 

 (19.2), tarsus 47.1-51.0 (48.4) mm. 



Females (3 from Panama and Colombia), wing 285-299 (290.6) 

 tail 170-185 (175.1), culmen from cere 17.8-20.1 (19.0), tarsus 45.1- 

 48.0 (46.8) mm. 



Resident. Local in eastern Panama ; recorded in Darien ( Yaviza, 

 taken by P. L. Slattery; Aruza; Cerro Pirre to 600 meters) ; and San 

 Bias ( Perme, Ranchon, Puerto Obaldia) . 



Near Cana, on Cerro Pirre, Goldman secured 2 specimens in the 

 lower edge of the Subtropical Zone, the only record outside the low- 

 lands. In the preserved stomach of one of these I found fragments 

 of several large roaches, bits of locustids, and 3 cerambycid beetles of 

 large size. Goldman's notes record a caterpillar, orthoptera, and bits 

 of beetles in the other. 



Several specimens taken by Wedel in the eastern San Bias make it 

 probable that distant nocturnal calls heard at our camp at Quebrada 

 Venado near Armila, that I did not recognize, may have come from 

 these owls. 



Beyond Panama this race has a considerable range in northwestern 

 Colombia, from Choco and the eastern side of the Gulf of Darien to 

 the middle Magdalena Valley. 



This race is named for Hasso von Wedel who collected the type 

 material.
