WOODPECKERS. Order XV. PICI. Family PICIDAE Woodpeckers are well known birds having sharp chisel-like bills, sharply pointed and stiffened tail feathers, and strongly clawed feet with two toes forward and two back, except in one genus. Their food is insects and grubs, which they get by boring in trees, and from under the bark, clinging to the sides of trunks or the under side of branches with their strong curved nails, aided by the tail, for a prop. They are largely resident where found. 392. IVORY-BILLED WOODPECKER. _Campephilus principalis._ Range.--Locally distributed, and rare, in Florida, along the Gulf coast and north casually to South Carolina and Arkansas. This is the largest of the Woodpeckers found within our borders, being 20 inches in length. But one other American species exceeds it in size, the Imperial Woodpecker of Mexico, which reaches a length of nearly two feet; as this species is found within a few miles of our Mexican border, it may yet be classed as a North American bird. The present species has a large, heavy, ivory-white bill. They can readily be identified, at a great distance, from the Pileated Woodpecker by the large amount of white on the secondaries. They used to be not uncommonly seen in many sections of the southeast but are now found very locally and only in the largest and remote woods. They nest in holes in large trees in the most impenetrable swamps; laying three, and probably as many as six pure white glossy eggs measuring 1.45 × 1.00.

HAIRY WOODPECKER. _Dryobates villosus villosus._ 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 Woodpecker. 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 × .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. 393a. NORTHERN HAIRY WOODPECKER. _Dryobates villosus leucomelas._ Range.--North America, north of the United States. Slightly larger than the preceding. 393b. SOUTHERN HAIRY WOODPECKER. _Dryobates villosus auduboni._ Range.--Southern United States; north to South Carolina. Similar to the Hairy Woodpecker, but smaller.
