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 x .67). 
NORTHERN PILEATED WOODPECKER. 
405a. Phlceotomus 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 grad¬ 
ually driven farther north or into the mountain regions, where 
they can find the heavy timber in which they make their homes.
