DENDROCOLAPTES PICUMNUS Lichtenstein: Black-banded 

 Woodcreeper, Trepador Rayado 



Dendrocolaptes Picwnnus Lichtenstein, Abhandl. Kon. Akad. Wiss. Berlin for 

 1818-1819, Phys. Kl., 1820, p. 202. (Cayenne.) 



Similar to the Barred Woodcreeper, Dendrocolaptes certhia, but 

 with crown, side of head and neck, and foreneck streaked with pale 

 buff to buffy white. 



Description. — Length 240-260 mm. Adult (sexes alike), crown 

 and hindneck grayish brown, with narrow shaft lines of buffy 

 white ; back, scapulars, and wing coverts olive-brown, the upper back 

 usually with shaft lines of buffy white; rump and upper tail coverts 

 cinnamon-rufous; secondaries and inner primaries similar, but 

 darker ; outer webs of outer primaries olive-brown ; tail chestnut, 

 with the shafts much darker ; side of head blackish brown, streaked 

 with white or buffy white ; chin and throat white to clay color, the 

 feathers edged with brown ; lower foreneck olive-brown to grayish 

 brown streaked with buff, these streaks lined narrowly on either side 

 with black ; rest of under surface buffy brown, barred narrowly with 

 black ; the streaking lighter on tibiae and flanks ; under tail coverts 

 varying from the paler hue of the abdomen to cinnamon ; under wing 

 coverts cinnamon-buff, barred with black ; under surface of primaries 

 and secondaries light cinnamon-rufous, tips of the primaries dusky 

 gray. 



The species is widely distributed from Guatemala and Honduras 

 through Central America and South America to northern Argentina, 

 Paraguay, and Brazil. Two geographic races may be recognized in 

 Panama. 



Little is known of the life of these birds except that their tree- 

 climbing habits are typical of the family. Sclater and Salvin (Proc. 

 Zool. Soc. London. 1879, p. 523) cite a note from Salmon made in 

 Antioquia, northwestern Colombia, that the nest "is made in a hole 

 in a tree, and the number of eggs two." The two eggs in the set 

 collected, now in the British Museum, identified as Dendrocolaptes 

 picitmnits mitltistrigatus, a form slightly larger than those found in 

 Panama, are white and measure 29.2 X 21.6 mm.
