122 PICI: Woodpeckers 



BATCHELDER WOODPECKER 



(394b. Dryobates pubescens homorus) 6^ in. 



The Rocky Mountain form of Downy Woodpecker. Slightly 

 larger and whiter than the Willow subspecies, from which it 

 is separated by the lofty Sierra Nevada northward and by 

 deserts southward. Identical in general appearance and hab- 

 its, except as affected by different habitat. 



These small Woodpeckers often work near the ground, some- 

 times on large weed-stems and even on standing dead corn- 

 stalks. 



ARIZONA WOODPECKER 



(398. Dryobates arizonae) 8 in. 



A brown Woodpecker, the only one in North America answer- 

 ing this description. Upper parts solid plain brown; below dark 

 brown spotted on soiled white; a white line on cheek ends in a 

 patch on sides of neck. The male has a red nape-band; the 

 female none. 



Said to be less suspicious, or perhaps more stupid, than most 

 birds of its tribe. 



ALPINE THREE-TOED WOODPECKER 



(401b. Picoides americanus dorsalis) 9| in. 



A rather large Woodpecker, chiefly black above; a narrow stripe 

 of black-and-white cross-barring extends from neck to rump, 

 generally not well defined, but in extreme cases almost solid 

 white; cheek largely white; croww-patch bright yellow in male, in 

 the female black, speckled with white. 



Said to be a very silent bird. 



SOUTHERN WHITE-HEADED WOODPECKER 

 (399a. Xenopicus albolarvatus gravirostris) 9 in. 



Black, with white head, white wing-patch, and red nape. The 

 wing-patch is very conspicuous in flight, and with the white 

 head is distinctive. Female lacks the red nape. 



Uses bill more to pry off the loose bark, in search of food, 

 than to peck. Feeds young largely on ants. Rather silent except 

 in flight, or when just about to take flight.
