ClincherThe odd one out — brown, barred back, black-spotted belly, a black chest crescent, and a white rump that flares in flight over salmon-red underwings.
White rumpGround-feederRed malar (♂)
"Red-shafted" is the resident form here — grey face, brown crown, red moustache on males. Feeds on ants on lawns and trails as often as on trunks. Loud "klee-yer" and long rolling "wik-wik-wik." Intergrades happen — see §05/§06.

ClincherTiny, with a short stubby bill (~⅓ of the head) and barred/spotted white outer tail feathers. The bill and the tail, not the size.
Stubby billBarred outer tailRed nape (♂)
The default backyard woodpecker — feeders, weed stems, thin twigs a Hairy would never work. Gentle, small-headed look. Soft "pik"; whinny descends. Full split in §03.

ClincherA bigger Downy with a long chisel bill (~a headlength) and clean, unmarked white outer tail feathers. Starched, big-headed, "serious" look.
Long billClean white tailBig-headed
Prefers larger trunks and canyons over feeders; more wary. Sharp, emphatic "peek"; rattle stays on one pitch. The Downy/Hairy pair is this key's whole reason for §03.

ClincherStriped face, a long white wing-slash, red forecrown and a small red nape spot — the "naped." Throat sexes the bird (see §05).
Red nape spotWhite wing-slashSap wells
The regular sapsucker here — aspen and mixed woodland, drilling tidy horizontal rows of wells. Male's throat is fully red; female shows a white upper throat/chin. Nasal, cat-like mew.

ClincherTwo birds in one species. Male: glossy black, white face lines, white wing patch, red throat, yellow belly. Female: brown head, zebra-barred back, black chest patch — no red at all.
Extreme dimorphismConifer/aspenMontane
The female was once described as a separate species — she looks nothing like the male (§05). A higher-elevation conifer-and-aspen bird; countywide frequency undersells it (§06). Drums an irregular, stuttering roll.
Uncommon · 3.5% at peak (Jul) — montane, see §06
ClincherNo white stripe down the back — instead a barred/laddered black-and-white back — a yellow crown patch (male), and a face with less white than a Hairy. High spruce-fir and burns.
Yellow crown (♂)Barred backSpruce-fir / burns
Flakes bark off dead conifers, often quietly, in the upper canyons. Habitat is the finder: not a valley bird. Countywide frequency undersells it where the habitat exists (§06).

ClincherUnmistakable when seen well: dark green-black above, a silvery-grey collar and breast, a rosy-pink belly, and a slow, crow-like flight. Sallies out to catch insects like a flycatcher.
Pink bellyFlycatchesOak / cottonwood
Perches upright and conspicuous on snags and wires — doesn't act like a woodpecker. Irregular and local; fall/winter movements peak here in Oct–Nov. Mostly silent.
