120 APPENDIX 



Southern Oregon and California west of Sierra Nevada 

 and Cascade Ranges; most common in the oak belt of 

 the foothills. 



Easily distinguished from Downy Woodpecker by being 



barred on the back, instead of striped. 



7. DRYOBATES ARIZONA, Arizona Woodpecker. 



Upper parts plain brown, not spotted nor streaked; primaries 

 dotted with fine white dots; outer tail feathers barred; 

 under parts white, thickly spotted (except throat), with large, 

 round, brown spots. $ with red occipital band. 7.5-8.5 

 inches. 



Southern Arizona and southwestern New Mexico; among 

 oaks of the foothills from 4000 to 7000 feet elevation. 



8. XENOPICUS A^BOLARVATUS, White-headed Woodpecker. 



Glossy black all over, except showy white patch on prima- 

 ries, and head and throat pure white (forehead and crown 

 sometimes grayish). $ with broad occipital band of scarlet. 

 9 inches. " Iris pinkish red " (Bendire). 



Mountains of Pacific coast, east to western Nevada and 

 western Idaho, usually in the pine and fir forests above 

 4000 feet altitude. 



9. PICOIDES ARCTIC us, Arctic Three-toed Woodpecker. 



Glossy black above, unmarked except by fine white spots on 

 primaries; under parts grayish white, sides thickly barred 

 black and white; three outer pairs of tail feathers white, 

 sides of throat with broad white stripe. $ with large crown 

 patch of deep yellow. 9.5 inches. 



British America, south into the northern tier of States 

 and into the Sierra Nevada Mountains to Lake Tahoe. 

 Most commonly seen in the track of forest fires, where it 

 is usually abundant for about two years ; rare outside of the 

 extensive soft wood tracts, and usually found singly or in 

 pairs except when on burnt land. I have found this species 

 far more common than the next, and the best mark in life 

 to be the white stripe on the neck, in distinction from the 

 white line of P. americanus.
