Northern Flicker

October 13, 2011 by buffalostevep

A large woodpecker that spends much time on the ground rooting through brush and grass here in the Murray Valley. The pair I photographed last year was picking berries from a Hackberry Tree:

Northern Flickers are large, brown woodpeckers with a gentle expression and handsome black-scalloped plumage. On walks, don’t be surprised if you scare one up from the ground. It’s not where you’d expect to find a woodpecker, but flickers eat mainly ants and beetles, digging for them with their unusual, slightly curved bill. When they fly you’ll see a flash of color in the wings – yellow if you’re in the East, red if you’re in the West – and a bright white flash on the rump.

Although it can climb up the trunks of trees and hammer on wood like other woodpeckers, the Northern Flicker prefers to find food on the ground. Ants are its main food, and the flicker digs in the dirt to find them. It uses its long barbed tongue to lap up the ants.
The red-shafted and yellow-shafted forms of the Northern Flicker formerly were considered different species. The two forms hybridize extensively in a wide zone from Alaska to the panhandle of Texas. A hybrid often has some traits from each of the two forms and some traits that are intermediate between them. The Red-shafted Flicker also hybridizes with the Gilded Flicker, but less frequently.
The Northern Flicker is one of the few North American woodpeckers that is strongly migratory. Flickers in the northern parts of their range move south for the winter, although a few individuals often stay rather far north.
Northern Flickers generally nest in holes in trees like other woodpeckers. Occasionally, they’ve been found nesting in old, earthen burrows vacated by Belted Kingfishers or Bank Swallows.
Like most woodpeckers, Northern Flickers drum on objects as a form of communication and territory defense. In such cases, the object is to make as loud a noise as possible, and that’s why woodpeckers sometimes drum on metal objects. One Northern Flicker in Wyoming could be heard drumming on an abandoned tractor from a half-mile away.
The oldest known “yellow-shafted” Northern Flicker lived to be at least 9 years 2 months old, and the oldest “red-shafted” Northern Flicker lived to be at least 8 years 9 months old.
Look for Northern Flickers in woodlands, forest edges, and open fields with scattered trees, as well as city parks and suburbs. In the western mountains they occur in most forest types, including burned forests, all the way up to treeline. You can also find them in wet areas such as streamside woods, flooded swamps, and marsh edges.
Northern Flickers eat mainly insects, especially ants and beetles that they gather from the ground. They also eat fruits and seeds, especially in winter. Flickers often go after ants underground (where the nutritious larvae live), hammering at the soil the way other woodpeckers drill into wood. They’ve been seen breaking into cow patties to eat insects living within. Their tongues can dart out 2 inches beyond the end of the bill to snare prey. Other invertebrates eaten include flies, butterflies, moths, and snails. Flickers also eat berries and seeds, especially in winter, including poison oak and ivy, dogwood, sumac, wild cherry and grape, bayberries, hackberries, and elderberries, and sunflower and thistle seeds.
