34 PACIFIC COAST AVIFAUNA No. 10 



137. Picoides americanus dorsalis Baird. 



Alpine Three-toed Woodpecker. 



Status — A resident of the Canadian zone (pine and spruce belts) of the 

 White, Mogollon and San Francisco mountains (Henshaw, 1875b, p. 391 ; 

 Mearns, 1890a, p. 252). 



138. Sphyrapicus varius nuchalis Baird. 



Red-naped Sapsucker. 



Synonyms — Picas varius; Sphyrapicus varius; Sphyrapicus nuchalis. 



Status — A fairly common migrant, and, in extreme southern Arizona and 

 along the Colorado River, a winter visitant. It has several times been reported 

 as "resident" in northern Arizona, but I know of no authentic breeding record. 



[39. Sphyrapicus thyroideus (Cassin). 



Williamson Sapsucker. 



Synonym — Sphyrapicus williamsonU. 



Status — Common resident in the Canadian zone of the higher parts of the 

 White, Mogollon and San Francisco mountains (Mearns, 1890a, p. 252). Farther 

 south it is a fairly common migrant and winter visitant in the mountains, while it 

 has once been reported from the Colorado River, at Fort Mohave (Cooper, 1861, 

 p. 121). 



140. Melanerpes erythrocephalus (Linnaeus). 



Red-headed Woodpecker. 



Status — A single specimen was taken by Price in the Chiricahua Mountains, 

 in the spring of 1894 ( Bendire, 1895, p. 107). This is the only record for Ari- 

 zona. 



141. Melanerpes formicivorus aculeatus Mearns. 



Mearns Woodpecker. 



Synonyms — Melanerpes formicivorus; Melanerpes formicivorus bairdi; 

 Melanerpes melanopogon, part; Balanosphyra fonnicirora aculeata. 



Status — A common resident of the live-oak regions. In northern Arizona 

 ranges from the Grand Canon of the Colorado ( Merriam, 1890, p. 39), and Bill 

 Williams Mountain (Wetmore, 1908, p. 379) — but not on San Francisco Moun- 

 tain (see Merriam, 1890, p. 92) — west to the Hualpai Mountains (Stephens, 

 1903, p. 101) and Fort Whipple (Coues, 1866a, p. 55); extends southeastward- 

 ly throughout the state, on the southern boundary ranging west to the Santa Rita 

 Mountains. Absent from the arid southwestern portion, all that would be south 

 and west of a line drawn from the Hualpai to the Santa Rita Mountains. Re- 

 ported as a straggler at Sacaton, September 5, 1910 (Gilman, 1911a, p. 35).
