Hairy Woodpecker

The larger of the two black-and-white woodpeckers, with a bill roughly as long as its head is deep. It is warier than a downy, needs bigger trees, and takes longer to trust a feeder.

The Hairy Woodpecker (Dryobates villosus) is a black-and-white woodpecker about 9.5 inches (24 cm) long, roughly robin-sized, with checkered wings, a broad white stripe down the back, and a red nape patch on males. Its plumage is close to identical to the Downy Woodpecker, and the difference that matters is the bill: a hairy's is roughly as long as its head is deep, a genuine chisel.

Feeder owners meet it less often than the downy, and not because it is rare. Hairies hold large territories in mature woodland, avoid small fragmented woodlots, and are noticeably warier around houses. A yard that gets three downy visits an hour may get one hairy a week.

This profile covers the identification in detail, what hairies need in a landscape, how they feed, the suet setup most likely to bring one in, their nesting requirements, and why dead wood is the limiting resource for the species.

How to identify a Hairy Woodpecker#

The plumage is the standard small-woodpecker pattern: black crown, white stripe above and below the eye, a broad white stripe down the center of the back, black wings spotted with white, clean white underparts, and black wings and tail. Males have a red patch at the back of the head; females have none. Young birds may show scattered red on the crown.

What identifies a hairy is proportion and bearing. It looks front-heavy and long-billed, with a large angular head, a solid neck and a substantial body. Where a downy suggests a small bird wearing a woodpecker costume, a hairy looks like a working tool.

The voice is louder and sharper. The call is an emphatic peek, higher and more forceful than a downy's soft pik, and the rattle call runs at an even pitch rather than descending. The drum is fast, long and ends abruptly.

Regional variation is real but rarely confusing: Pacific coast birds are smaller and dingier below, northern and Rocky Mountain birds are larger and whiter. Bill proportion holds across all of them.

Hairy or Downy: use the bill against the head#

The two species overlap across nearly all of North America, so this is the most common woodpecker identification question there is. Work through it in this order.

1. Bill length against head depth. This is the reliable mark, and the only one that works on a lone bird with nothing to compare it against. Look at the bill, then at the depth of the head from crown to throat. A hairy's bill is roughly as long as the head is deep. A downy's is markedly shorter, about a third to a half of that depth, and looks like a small chip stuck to the face.

2. Overall size. A hairy is about 9.5 inches (24 cm) and weighs two to three times what a downy does. Size is convincing when both species are at the same feeder and unreliable on a distant lone bird, which is why the bill comes first.

3. Outer tail feathers. A hairy's white outer tail feathers are plain. A downy's carry black spots or bars. You need a spread tail or a view from below, but the mark is decisive when you get it.

Where and when you will see one#

Hairy Woodpeckers live in mature forest of almost every kind: deciduous, coniferous and mixed, plus older woodlots, wooded swamps, mountain pine and fir, and larger parks. They generally avoid small isolated stands of trees, which is where downies thrive.

They do not migrate. A pair holds a large territory year-round, often on the order of tens of acres, which by itself explains why your neighborhood supports several downies and perhaps one hairy.

They join mixed winter flocks loosely rather than closely, and they turn up at feeders most reliably from November through March. Visits are short. A hairy typically feeds hard for half a minute and leaves, and it is quick to abandon the feeder if you move behind a window.

What Hairy Woodpeckers eat#

Roughly three quarters of the natural diet is animal matter, and the specialty is wood-boring beetle larvae. A hairy chisels through bark and into sound wood to reach grubs that shallower foragers cannot get at, and this is where the heavy bill earns its keep. Ants, caterpillars, spiders and bark beetles fill in the rest, with seeds, nuts and berries making up the plant portion.

Two habits are worth watching for. Hairies follow pileated woodpeckers and feed on insects exposed by their much larger excavations, and they drink sap from the neat rows of wells drilled by sapsuckers.

At feeders, the order is predictable:

• Suet, the most effective food by a wide margin.
• Shelled peanuts, taken readily, especially in cold weather.
• Black oil sunflower and sunflower hearts, taken steadily.
• Homemade suet or peanut butter dough in winter, useful when temperatures stay low.

The feeder setup that works#

The feeder is not the hard part. Getting a wary bird from a large territory to include your yard in its route is.

Use a sturdy suet feeder with a tail prop, the extended panel below the cage that lets the bird brace its stiff tail as it would on a trunk. A hairy is heavy enough that a swinging cage in open air is genuinely awkward for it, and mounting the feeder flat against a tree trunk or a pole at 5 to 6 feet (1.5 to 1.8 m) roughly matches its natural feeding posture.

A peanut feeder is the second food. Whole or halved kernels are worth more per trip to a large bird than sunflower seed, and mesh tubes are stable enough for a hairy to work.

Behavior worth knowing#

Hairy Woodpeckers work vertically and methodically. A bird lands low on a trunk, hitches upward in short jumps, taps and probes, then flies to the base of the next tree and repeats. Compared with a downy's twitchy work on twigs and stems, it looks deliberate.

Excavation is the difference that matters ecologically. A hairy can dig into wood hard enough to reach larvae several inches deep, and the holes it leaves are used later by insects, fungi and other birds. Outbreaks of bark beetles, and burned stands full of dying trees, can draw hairies in unusual numbers for a few years.

Drumming starts in late winter. Both sexes drum, and the roll is faster and longer than a downy's and stops abruptly at the end. Like all woodpeckers they favor resonant surfaces, so gutters and metal flashing get used as amplifiers. This is signaling, not damage.

Nesting#

Hairy Woodpeckers excavate a fresh cavity each spring, most often in a live tree with decayed heartwood or in a large dead limb, typically 10 to 30 feet (3 to 9 m) up. Both sexes dig, and the entrance is a neat hole about 1.5 inches (4 cm) across, often placed under a limb or on the sheltered side of the trunk.

The cavity gets no lining beyond woodchips. Clutches usually run 3 to 6 white eggs, incubation takes about 12 days, and the young stay in the nest roughly four weeks, which is longer than a downy. One brood a year is the rule.

Nest boxes are almost never used. Because they excavate and prefer to, the only useful thing a yard can offer is large trees and standing dead wood. Abandoned hairy cavities go on to house nuthatches, chickadees, bluebirds, kestrels and flying squirrels, so a single nest tree pays out for years.

Population and outlook#

Hairy Woodpecker numbers are broadly stable across North America, and the species occupies a very large range in a wide variety of forest. It is not of conservation concern at the continental scale.

Local abundance tracks dead wood closely. Salvage logging after fires and insect outbreaks removes exactly the standing dead trees that produce peak hairy densities, and clearing snags out of suburbs has the same effect on a smaller scale. Fragmentation matters too, since hairies use large woodlots and skip small ones.

A setup that brings a Hairy Woodpecker in#

• A sturdy suet cage with a tail prop, mounted on a trunk at 5 to 6 feet (1.5 to 1.8 m).
• A quiet corner of the yard, on the side nearest mature trees, away from doors.
• Whole shelled peanuts as the second food, in a mesh feeder that will not swing wildly.
• A second suet feeder several yards off, so the smaller birds still get fed.
• Patience, measured in weeks rather than days.
• Large trees and standing dead wood kept wherever it is safe, which is the one thing no feeder can replace.
