Nuttall's Woodpecker

Nuttall's Woodpecker is closely tied to oak woodland and adjacent riparian growth in California and northern Baja California, occupying a range that mostly complements rather than overlaps that of the similar Ladder-backed Woodpecker. The two species can be confused, but subtle differences in barring and underpart cleanliness help separate them.

It shows the same general black-and-white barred back pattern found in many small Dryobates woodpeckers, paired with a distinctive solid black band across the nape.

• Back: black-and-white barred, similar in general pattern to Ladder-backed Woodpecker
• Nape: solid black band, a useful mark separating it from Ladder-backed Woodpecker
• Underparts: cleaner white with little to no flank spotting
• Crown: red patch on males, confined to the rear crown; females show plain black
• Vs. Downy Woodpecker: Nuttall's is larger with more extensive back barring and lacks the crisp white back stripe of Downy Woodpecker

Males show a red patch on the rear crown while females have an all-black crown. Juveniles are duller with softer barring and, in young males, a less defined red crown patch. The species undergoes one complete annual molt following breeding.

Resident in oak woodland, oak-conifer edge, and riparian corridors across California west of the Sierra Nevada and into northern Baja California. It is largely non-migratory, remaining on territory throughout the year.

Forages on oak trunks and branches, gleaning bark-dwelling insects and their larvae, and will also visit riparian willows and cottonwoods. It nests in cavities excavated in dead limbs or trunks, often in oaks. Its calls include sharp rattling notes similar to Ladder-backed Woodpecker, and it drums in short, quick bursts.
