30. Crax alberti Fraser. 



Crax alberti BANGS, Proc. Biol. Soc. Wash. XII, 1898, 132. Santa Marta. 



Three specimens, i adult and 2 chicks, Bonda, July 21 and 26, 

 and Naranjo, July. 



Young birds in first plumage show little resemblance to the 

 adults, and may be thus described : 



Frontlet and broad superciliaries dark rufous, with a similar line running 

 from the angle of the mouth beneath the ear-coverts, which are deep buffy ; top 

 of the head blackish with a median and a broad lateral stripe on each side gray, 

 the gray occupying only the tips of the feathers ; nape blackish, more or less 

 rufous on the median line ; back mixed chestnut and blackish with many buffy- 

 tipped feathers on the anterior portion, and posteriorly a broad white band on 

 each side passes from the middle of the dorsal region to the base of the tail ; 

 tail black, tipped and varied with pale rufous ; wings with the lesser coverts 

 uniform rusty brown, the middle and greater coverts black broadly edged with 

 rufous ; quills black, the primaries broadly edged with rufous, the secondaries 

 conspicuously barred with rufous ; chin, throat, abdomen and thighs buffy 

 white ; breast dark ferruginous on the sides but lighter on the middle line ; bill 

 and feet flesh color. The only resemblance to the adult is the color pattern of 

 the wings, in which the narrow white crossbars in the adult are replaced by 

 broader rufous bars in the young.
