Meet the black sheep of the woodpecker family: the Northern
Flicker. They’re decked out in spots and bands instead of the typical black-and-white
plumage, and they prefer to eat ants and beetles off of the ground instead of drilling
for insects in rotting wood. However, like other woodpeckers they excavate their
nests in trees and drum on hollow objects to defend their territory from other
birds. Wild Flickers will drum on hollow trees, but urban ones take advantage
of human metal, including ventilation pipes on houses and abandoned vehicles.
Because of their gaudy outfits, flickers are easy to
identify. In flight, their wings show bright red and their bums are bright
white, and when sitting their black and brown markings are unmistakeable. This one I saw November 11 at Sunset Beach Park. He was very
interested in this hole in the tree, maybe feeding on insects inside of it. (He’s
male because of his red moustache—the lady Flickers have plain gray faces.)
East of the Rockies, Northern Flickers have yellow wings
instead of red. The two colour morphs used to be considered separate species
before orithologists “lumped” them into one in the 1970s. The ‘70s was an era
of lumping for birds (Audubon and Myrtle Warblers both became Yellow-Rumped
Warblers, and six Junco species all became the Dark-eyed Junco) but scientists
have recently turned the tables and done more species splitting than lumping. I
wouldn’t be surprised if one day we were again calling this bird the Red-Shafted
Flicker. While we fret over the definition of a species and which birds belong
to which group, the birds continue to go about their daily lives unaware of our
struggle with systematics.
A flicker drumming on our ventilation pipe several years ago in Delta. The sound echoed through the whole house and was especially loud in the bathroom. |
