ucasanus._

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 x .65.

398. ARIZONA WOODPECKER. _Dryobates arizonae._

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 x
.60.

399. WHITE-HEADED WOODPECKER. _Xenopicus albolarvatus._

Range.--Western United States from southern California to southern
British Columbia.

This odd species is wholly a dull black color, except for the white head
and neck, and basal half of the primaries. They are quite abundant in
some localities, particularly in California on mountain ranges. They
nest at any height, but the greater number have been found under twenty
feet from the ground and in old pine stubs. They lay from four to six
glossy white eggs, measuring .95 x .70. They are said to be more silent
than others of the Woodpecker family, and rarely make the familiar
tapping and never drum. It is claimed that they get at their food by
scaling bark off the trees, instead of by boring.

400. ARCTIC THREE-TOED WOODPECKER. _Picoides arcticus._

As implied by their name, members of this genus have but three toes, two
in front and one beh
