This black and white species may be known from any other because of the uniform black crown and nape, the male having a small dot of red on either side of the crown, back of the eye. They are quite abundant in the Gulf States and Florida, where they nest during April and May, and in some localities in March. They build in hollow trees or stumps at an elevation from the ground, laying from three to six glossy white eggs; size .95 × .70.

TEXAS WOODPECKER. _Dryobates scalaris bairdi._ Range.--Southwestern United States from southern Colorado south to northern Mexico. This species is brownish white below, has the back barred with black and white, and the male has the whole crown red, shading into mixed black and whitish on the forehead. Its habits and nesting are just the same as those of the Downy, but the three or four white eggs, that they lay in April, are larger; size .80 × .65. 396a. SAN LUCAS WOODPECKER. _Dryobates scalaris lucasanus._ Range.--Lower California, north to the Colorado Desert, California. Very similar to the last; less barring on the outer tail feathers. Eggs the same. 397. NUTTALL'S WOODPECKER. _Dryobates nuttalli._ Range.--Pacific coast from Oregon south to Lower California. Similar to the Texan Woodpecker but whiter below, with whitish nasal tufts, and the fore part of the crown black and white striped, the red being confined to the nape region. They nest in holes in trees, either in dead stumps or in growing trees, and at any height above ground. During April or May they deposit their white glossy eggs upon the bottom of the cavity. The eggs measure .85 × .65. 398. ARIZONA WOODPECKER. _Dryobates arizonæ._ Range.--Mexican border of the United States, chiefly in Arizona and New Mexico. This species is entirely different from any others of our Woodpeckers, being uniform brownish above, and soiled whitish below, spotted with black. The male bird has a red crescent on the nape. They are said to be fairly abundant in some sections of southern Arizona. Their nesting habits do not vary from those of the other Woodpeckers found in the same regions, and they show no especial preference for any particular kind of a tree in which to lay their eggs. The nesting season appears to be at its height in April. The pure white eggs average in size about .85 × .60. [Illustration 254: Red-cockaded Woodpecker.
