i^o. 2.] HOFFMAN ON THE BIRDS OF NEVADA. 239 



PICID^. 



Picus villosus harrisi (And.) Allen. — Harris's Woodpecker. 



Not uncommon in the timbered districts over the greater portion of the 

 State. None were seen in the southern regions, however, although Br. 

 Kennerly notes it as descending to the eastern branches of the Colorado 

 Eiver in winter. 



Picus puhescens gairdneri (Aud.) Coues. — Gairdner's Woodpecker. 



Mr. Eidgway states this species to be unaccountably rare, a few being 

 found in September among the thickets by one of the streams flowing 

 from the lofty- Clover Mountains into the Upper Humboldt. 



Pirns scalaris Wagl. — Texan Woodpecker. 



Abundant in the Colorado Valley, and sometimes seen on the bushes 

 covering the neighboring mountains. In habits they are the exact rep- 

 resentatives of P. nuttalU, which they so much resemble. — {Cooper.) 



Xenopicus albolarvatus (Cass.) Baird. — White-headed Woodpecker. 



Was found common by Mr. Eidgway on the eastern slopes of the 

 Sierra Nevada, near Carson City, during the winter, keeping entirely 

 among the pines, though sometimes coming down to the lower edge of 

 the woods. 



Picoides arcticus (Swains.) Gray. — Black-backed Three- toed Woodpecker. 

 One specimen only was found by Mr. Eidgway near Carson City in 

 February. 



Spliyrapicus varius nuclialis Baird. — Eed-naped Woodpecker. 



Eather common in favorable localities throughout the northern regions. 

 Dr. Cooper obtained a female specimen at Fort Mojave in February, 

 which he thinks may have wandered in a storm from the mountains, 

 being the only one he saw. 



Sphyrapicus varius riiber (Gmel.) Eidgw. — Eed-breasted Woodpecker. 



Occurs chiefly on the western slope of the Sierra Nevada, though Mr. 

 Eidgway is under the impression that he saw it once near Carson City. 

 Mr. Heushaw has obtained it at Lake Tahoe since the time of the for- 

 mer's observations. 



Sphyrapicus thyroideus (Cass.) Baird. — Black-breasted Woodpecker. 



Found throughout the elevated coniferous regions. This species was 

 formerly considered a species distinct from S. iciUiamso7Uj when in fact 

 they are female and male of the same species, a fact first pointed out 

 by Mr. Henshaw in 1874.* Dr. Cooper found his first specimen a strag- 

 gler to the Colorado Valley in the winter of 18G1.
