BIRDS OF THE REPUBLIC OF PANAMA PART 4 



Azul/Jefe area of the Province of Panama, where, in 1911, E. A. 

 Goldman found it common from 750 m to the summit of Cerro Azul. 

 Ridgely (in Htt.) notes that this is one of the more numerous species 

 in the windswept elfin forest near the summit of Cerro Jefe. 



On November 12, 1970, Eugene S. Morton collected a juvenile male 

 on Cerro Jefe; it had little fat, weighed 49.5 g, and the skull was not 

 ossified. It was still being fed by an adult; the stomach contained small 

 reptile bones and much gravel. 



Though known only from two widely separated mountains, it is pos- 

 sible that these birds are distributed locally along the higher ridges of 

 the Serrania del Darien and the Cordillera de San Bias between the 

 two points in question. 



ATLAPETES TORQUATUS ATRICAPILLUS (Lawrence) 



Buarrcmon atricapillus Lawrence, 1874, Ann. Lyc. Nat. Hist., New York, 10, p. 

 396. ("Bogota," Colombia.) 



Characters. — Crown nearly entirely black. 



Measurements. — Males (6 from Darien and Colombia), wing 81.2- 

 91.0 (87.3), tail 73.0-85.7 (81.7), oilmen from base 16.0-18.4 (17.7), 

 tarsus 29.7-32.2 (30.8) mm. 



Females (7 from Darien and Colombia), wing 80.0-85.7 (82.4), tail 

 71.8-82.6 (77.8), oilmen from base 16.7-18.2 (17.7), tarsus 27.5-31.0 

 (30.0) mm. 



Resident. Known in Panama only from Cana, Darien, where birds 

 were collected between 600 and 670 m by E. A. Goldman in 1912 and 

 R. R. Benson in 1928. It is also found in northern Colombia. Griscom 

 (Bull. Mus. Comp. Zool., vol. 69, April, 1929, p. 185) assigned the 

 specimens collected by Benson to the race tacarcunae , but all 4 of Gold- 

 man's skins in the Smithsonian have only the faintest traces of the gray 

 superciliary stripes and only 2 retain a hint of the median crown stripe. 

 Although they can be considered intergrades, they are closer to atrica- 

 pillus than to tacarcunae.

 brown, bordered by thin brownish yellow stripe; rest of upper surface 

 olive-green; undersurface mostly white, with black pectoral band and 

 gray sides and flanks.
