About the Nuttall's Woodpecker
Endemic to oak and missed woodlands in California and northwestern Baja California, the Nuttall’s is closely related to the ladder-backed. Monotypic. Length 7".
“Ladder-back” pattern; spotted sides; barred flanks; auriculars almost wholly black; uppermost back black. Sexes similar but females lack red patch on nape and hindcrown.
Compared with ladder-backed, Nuttall’s shows more black on face; white bars on back are narrower; more extensive black on upper back below nape; white outer tail feathers sparsely spotted rather than barred. Nuttall’s underparts are purer white below, more cleanly spotted and barred with black; ladder-backed’s underparts are washed with buffy, and markings are finer but often extend across the breast as short streaks. Nuttall’s nasal tufts are usually white (buffy to dusky in ladder-backed). Red of male is restricted on Nuttall’s; in ladder-backed red covers most of crown, but is spotted with black and white on forecrown. Calls differ markedly.
Call: a short, rolling prrt or pitit that may be followed by a longer trill, prrt prrt prrrrrrrrrrrrr; also a loud kweek kweek kweek series. Drum: A steady roll of about 20 taps over a second.
Status and Distribution
Common. Year-round: oak woodlands, mixed oak-conifer and oak-riparian woodlands, and tall dense chaparral; sea level to about 6,000 feet. Small populations extend onto deserts along riparian corridors. Vagrant: a few wander to deserts of south-central California, casually to Imperial Valley; southwestern Oregon, western Nevada.
