This, the western form of the Hairy Woodpecker, is the prevailing and 

 most abundant member of its tribe in the Middle Region, as also in all parts 

 of New Mexico and Arizona. In the summer, it retires to the mountainous 

 districts, finding its home chiefly among the pines, where also it is a resi- 

 dent species through the year; though in fall a partial migration takes place, 

 the birds not only in many instances removing to districts somewhat farther 

 south than the ones in which they passed the summer or were reared, but 

 also in fall a more or less general descent from the elevated pine region 

 takes place, and the species may then be observed among the deciduous 

 trees of the low valleys, and of the streams generally. 



They have a full share of the restless industry and indefatigable 

 energy so characteristic of the family, and from daylight to dark are busy 

 in their constant and oftentimes laborious quest for insects; the noise made 

 by their vigorous hammering on the dead limbs being a characteristic 

 sound in the pine woods of the West, where the numbers of this as well as 

 of several other species are very great. They are more or less terrestrial in 

 their habits, and, though less often seen moving about on the ground than the 

 Golden-winged Woodpecker, are not infrequently started from among the 

 bushes, where they find seeds, insects, etc.
