Woodpecker, Picoides scolaris
The Ladder-backed Woodpecker resembles the Nuttall's, but its preferred
southwestern habitat is desert rather than oak woods; the species' territories
are mostly distinct, with some overlap in Southern California. The Ladder-backed
male's crown extends further forward, to the eyes, sometimes manifested only
by scattered red feathers. Ladder-backs have buff or brown forehead and
underpart base, where Nuttall's are white.
