WILLIAMSON SAPSUCKER.
404. Sphyrapicus thyroideus. 9 inches.
A great variation in the plumage of this oddly marked bird is found. The male is mostly black on the back and breast, with a white rump, and with only a narrow patch of red on the throat; the under parts are bright yellow. The female is entirely different, being brownish in place of the black on the male, has no red on the throat, and on the back is barred with black and white.
Their nesting habits are the same as those of the family previously mentioned. Four to seven white eggs (.97 × .67).
NORTHERN PILEATED WOODPECKER.
405a. Phlœotomus pileatus albieticola. 17 inches.
This is one of the largest and strongest of the Woodpeckers; they are a sooty black on the upper parts and breast; the crest is long and bright red, and the male has a red line back of the eye; sides of the neck pure white, and patch of white on the wings. Female is more of a grayish black color than the male. As the large trees are being cut away in many localities where these birds were to be found, they are gradually driven farther north or into the mountain regions, where they can find the heavy timber in which they make their homes.
RED-HEADED WOODPECKER.
406. Melanerpes erythrocephalus. 9½ inches.
