Flickers Tapping Love Codes on my Roof

Flickers Tapping Love Codes on my Roof

Have you ever woken up to this sound [Flicker pounding on a roof] and wondered what in the world was going on? This is the sound of the Northern Flicker, a large, ant-eating woodpecker found in open woodlands, savannas, and forest edges throughout North America.
The western subspecies, the Red-shafted Flicker, can be found year round in Utah. Its largish brown body with spotted breast, and thin dark bars across its back are unmistakable. Both sexes have a black collar and a red spot on the head—males on the back of the head and females on the side.

Breeding season is when you’d be most likely to hear the flicker drumming loudly on your house or nearby trees. Flickers—like other woodpeckers–drum to attract mates and defend territory—they are not looking for food. Both sexes drum and you’ll usually hear the drumming in conjunction with their Long Call, [ play long call]

Flicker drumming is produced by rapidly and sharply beating the tip of the bill on some sort of resonating object, usually a dead tree, limb or branch, sometimes a metal surface. They will use aluminum siding, as well as the trim and fascia boards of wood, brick, and stucco homes. They’ll also go for metal downspouts, gutters, chimneys, and vents.

Scientists have measured just over one second as the average duration of drum roll, with averages of 22 to 25 total beats in drum roll.

Does it hurt the little fellow to bang his head repeatedly across a hard surface? No. Flickers and other woodpeckers have thickened skulls and powerful neck muscles that enable them to deliver sharp blows without damaging their internal organs. A spongy, elastic tissue connects these flexible joints between the beak and the skull acting as a shock absorber. Bristly feathers around the nostrils help filter out the wood dust created as the flicker pounds away.

Luckily for homeowners, holes made by drumming activities are usually just small, shallow dents in the wood. And the drumming usually stops once breeding begins in the spring. For the most part, flickers spend their time digging in the ground slurping ants with their long tongues. If a flicker really starts to get on your nerves—there are some things you can do to discourage his behavior–like hanging Mylar reflective tape or streamers to the area where he likes to drum. Personally, the sound doesn’t bother me once I know the source is an attractive bird whose taste in real estate just happens to be the same as mine.
