A practical guide to bird watching in Sonoma County, California

(Unless otherwise indicated, all phone numbers are in the 707 area code)

 

Permanent resident in the wooded areas of the county, but appears much more common in the winter months as birds come down to lower elevations and begin to appear in closer proximity to human activity, and birds from more northern populations move south to find warmer weather. Very common in suburban areas and parks in the winter. Less common in the flat, marshy areas in the southern extremes of the county. Generally looks and behaves like a woodpecker, but eats mostly ants and other insects, so much more likely to be seen on the ground than other woodpeckers and relatives--sometimes looking like a Robin as it searches for food in grassy or other open areas. Favors wooded areas with open ground nearby for foraging. Typical, undulating, woodpecker flight with a white rump patch and underwing and undertail color especially prominent in flight. Nests in most parts of Sonoma County. Usually quite wary of people.


Always distinctive, but can be confusing because Northern Flicker takes two forms and intergrades are not uncommon near range overlap and occasionally in our area from Autumn through Spring. However, we normally see the Western form, known as Red-shafted Flicker. Yellow-shafted Flicker is the common variety in the East. The most obvious difference is in the coloring of the underwing and undertail linings visible in flight; our flickers flash salmon pink when they fly or raise a wing (photo below). Eastern birds show yellow under the wings.


Otherwise, Northern Flicker is a comparatively large woodpecker with a proportionately large bill on a smallish head. The bill is slightly decurved. Overall, a beige-brown color but barred with black on the back and spotted with black on the paler flanks and belly. The black crescent-shaped “bib” at the upper breast is noteworthy (visible in photo below). White rump patch is conspicuous in flight and often shows between the tips of the folded feathers on perched birds. Males of the Western, reddish form have a red malar stripe or “mustache” on a somewhat greyer cheek than that of the male yellow form, which has a black mustache on a warmer cheek. Crown in the Western form typically browner than in the Eastern, Yellow-shafted form. The latter also sports a red patch at the nape, not present in the male birds we normally see (see photos below). Females of both forms lack the mustache, but Yellow-shafted females have the red nape patch. In other words, any Flicker you see in Sonoma County with a red patch at the nape is a Yellow-shafted Flicker out of its normal range (or may be an intergrade). The yellow-shafted form does show up here from time to time.


Gilded Flicker (Colaptes chrysoides), currently given full species status, has in the past been considered a subspecies of Northern Flicker. It’s very similar but not usually present in our area (native to southwestern Arizona, Baja California, and extreme northwestern Mexico). Some of the older sources given below (such as The Birder’s Handbook) treat Gilded Flicker as a subspecies of Northern Flicker.


Calls are worth studying, as Flickers can sound like Red-shouldered Hawks (Buteo lineatus), Pileated Woodpeckers (Drycopus pileatus), and even Steller’s Jays (Cyanocitta stelleri), which sometimes imitate the vocalizations of other birds.


Trivia: The pink tail and wing feathers were highly prized by native Americans for ornamental purposes (Fix and Bezener).
