Range. - United States east of the Plains and from North Carolina to Canada.
The Hairy Woodpecker or its sub-species is found in all parts of North America. The nesting habits and eggs of all the sub-species are not in any way different from those of the eastern bird, consequently what is said in regard to the eastern form will apply equally to all its varieties.
Except during the winter months, this species is not as commonly seen about houses or orchards as the Downy Wodpecker. During the summer they retire to the larger woods to nest, laying their eggs in holes in the trunks or limbs of trees at any height from the ground, and generally using the same hole year after year, and often twice or three times during one season, if the first sets are taken. They lay from three to six glossy white eggs; size .95 x .70. This species can be distinguished from the Downy Woodpeckers by their larger size (9 inches long), and the white outer tail feathers, which are unspotted.
