Woodpeckers:
The Complete Guide
What they eat, why they peck, every North American species, and a complete guide to woodpeckers by state — including our own pileated woodpecker on film
That sharp, rhythmic hammering echoing through the woods is one of the most distinctive sounds in North American wildlife. Woodpeckers are engineering marvels — birds that evolved to do something that would kill any other creature. On our 30-acre Private Lands Wildlife Habitat in Michigan, we've had the privilege of watching pileated woodpeckers, downy woodpeckers, and hairy woodpeckers work our trees year-round. This guide covers everything you need to know.
🪵 What You'll Find in This Guide
1. What Do Woodpeckers Eat?
Woodpeckers are primarily insectivores — they eat insects, and they're extraordinarily good at finding them inside wood where no other bird can reach. Their entire anatomy evolved around one goal: extracting food from trees that appear solid and impenetrable.
Primary Food Sources
Wood-Boring Insects
Carpenter ants, beetle larvae, and wood-boring grubs are the staple diet. A pileated woodpecker can smell carpenter ants through six inches of solid wood. One colony can feed a bird for days.
Nuts & Acorns
Acorn woodpeckers are famous for storing thousands of acorns in "granary trees." Many other species also eat nuts, seeds, and berries — especially in winter when insects are scarce.
Fruit & Berries
In late summer and fall, woodpeckers supplement their diet with wild fruit, poison ivy berries, and serviceberries. Red-bellied woodpeckers are especially fond of fruit.
Tree Sap
Yellow-bellied sapsuckers drill neat rows of shallow "sap wells" and return repeatedly to lap up the sap and eat the insects drawn to it — a unique foraging strategy among woodpeckers.
Leave dead and dying trees standing on your property when safe to do so. Snags — standing dead trees — are a woodpecker's most valuable food source. A single dead oak can support woodpeckers for years and eventually becomes cavity nesting habitat for owls and wood ducks.
What Woodpeckers Eat at Feeders
You can attract woodpeckers to feeders with the right foods. Suet is the single most effective woodpecker food — it mimics the fat and protein of insect larvae. Peanuts, peanut butter, sunflower seeds, and corn also work well. Downies and hairies will visit most backyard feeders; pileated woodpeckers occasionally visit large suet cages in wooded areas.
2. Why Do Woodpeckers Peck?
Woodpeckers peck for four distinct reasons — and understanding which one is happening tells you a lot about the bird's behavior and what it needs.
Foraging for Food
The most common reason. A woodpecker hammering irregularly, moving around the bark, is excavating for insects. The holes left behind are irregular and exploratory in shape.
Excavating a Nest Cavity
In spring, woodpeckers drill large, deep oval holes for nesting. This pecking is slower and more deliberate. Pileated woodpeckers create cavities large enough for wood ducks and owls to use after them.
Drumming to Communicate
Rapid, rhythmic drumming on resonant surfaces — sometimes your house — is territorial communication, equivalent to birdsong. They seek the loudest surface available, which is why metal gutters and chimneys are favorites.
Storing Food
Acorn woodpeckers and red-headed woodpeckers drill small holes to cache food for winter. A single acorn woodpecker family may store 50,000 acorns in one granary tree over a season.
If a woodpecker is drumming on your siding, it's communicating — not feeding. If it's excavating holes in your wood siding, it has found insects inside. The solution is to treat the insect problem, not harm the bird. Woodpeckers are federally protected under the Migratory Bird Treaty Act.
Why Do Woodpeckers Peck Wood — and Not Hurt Their Brains?
A woodpecker strikes wood at up to 25 kilometers per hour, 20 times per second. The forces involved would give a human a severe concussion with every strike. Woodpeckers survive because of four extraordinary adaptations working together: an extra-thick skull, a brain that fits tightly with almost no cerebrospinal fluid to slosh, a hyoid bone that wraps around the skull like a seatbelt absorbing shock, and a bill where the upper half is slightly longer than the lower, directing impact forces away from the brain.
3. Woodpecker Anatomy — Built to Hammer
| Feature | What It Does |
|---|---|
| Chisel-shaped bill | Drives into wood like a wedge; self-sharpening as it wears |
| Extra-long tongue | Can extend 4x the bill length; barbed tip spears grubs; wraps around skull for shock absorption |
| Zygodactyl feet | Two toes forward, two back — grips bark vertically without slipping |
| Stiff tail feathers | Acts as a third leg, bracing against the tree trunk while pecking |
| Thick skull | Spongy bone structure absorbs impact force before it reaches brain |
| Hyoid bone | Loops around entire skull, acts as a shock-absorbing harness |
4. Types of Woodpeckers in North America
North America has 22 woodpecker species, ranging from the tiny downy woodpecker at 6 inches to the spectacular pileated at nearly 20 inches. Here are the species most commonly seen across the eastern and central US.
The smallest and most common woodpecker in North America. Found in virtually every wooded habitat from Alaska to Florida. Males have a small red patch on the back of the head. Readily visits backyard suet feeders and is often the first woodpecker new birders identify. Range: all of North America except the far Arctic.
Looks nearly identical to the downy but is noticeably larger — about the size of a robin — with a longer, more powerful bill. Less likely to visit feeders in suburban areas; prefers mature forest. Found across North America in similar range to the downy. The bill-to-head ratio is the key ID feature: hairy woodpeckers have a longer bill relative to head size.
Despite the name, the red belly is almost never visible in the field — look for the brilliant red cap that runs from bill to nape on males. One of the most common woodpeckers in the eastern US and increasingly expanding its range northward. Loud and vocal, with a distinctive rolling "churr" call. Loves suet, fruit, and sunflower seeds at feeders.
One of the most striking birds in North America — entire head, neck, and throat are brilliant crimson. Once one of the most abundant woodpeckers in the east, populations have declined significantly due to habitat loss and competition for nest cavities. An excellent flycatcher, catching insects in mid-air. Listed as Near Threatened in some regions.
A migratory woodpecker known for drilling neat horizontal rows of small holes — "sap wells" — in tree bark. Returns to lap up sap and catch insects drawn to it. Found in forests across eastern North America; breeds in Canada and the northern US, winters in the south. Their characteristic well rows on birch, maple, and apple trees are easy to identify.
5. Pileated Woodpecker — Our Habitat Spotlight
🎥 Live on Our 30-Acre Private Lands Wildlife Habitat
Gratiot County, Michigan — Original footage from our property
We recently captured this pileated woodpecker working a tree right here on our habitat. Watch how it hammers with its full body, the chips flying, the characteristic rectangular holes taking shape. This is one of the most exciting wildlife sightings any landowner can have — and it's a sign your forest is healthy and mature enough to support the largest woodpecker in North America.
Pileated Woodpecker Facts
The pileated woodpecker (Dryocopus pileatus) is the largest woodpecker in North America at 16–19 inches — nearly the size of a crow. That flaming red crest is unmistakable. It is the bird that inspired the cartoon character Woody Woodpecker, and its loud, laughing call carries through the forest like nothing else.
- Primary food: carpenter ants — can smell a colony through 6 inches of solid wood
- Creates large rectangular holes, unlike the oval holes of other woodpeckers
- Those cavities become critical nesting habitat for wood ducks, owls, and flying squirrels
- Mates for life and defends a large territory year-round
- Requires mature forest with large diameter trees — an indicator of old-growth habitat quality
- Call is a loud, wild "wuk-wuk-wuk" laugh — often heard before the bird is seen
Seeing a pileated woodpecker on your land means you have mature trees with carpenter ant colonies — a sign of a healthy, established forest ecosystem. Leave large dead snags standing. The cavities pileated woodpeckers excavate are irreplaceable nesting sites for wood ducks, large owls, and flying squirrels.
6. Woodpeckers by State
Woodpecker species and abundance varies by region. Here's what to expect in each state covered — more states will be added as we document them from our habitat and field research.
🌲 Michigan Woodpeckers
Michigan hosts 8 woodpecker species. The downy, hairy, red-bellied, and red-headed woodpeckers are year-round residents. The yellow-bellied sapsucker and yellow-shafted flicker migrate through. The pileated woodpecker is present in mature northern forests — including right here on our Gratiot County habitat. The black-backed woodpecker is found in burned boreal forest in the UP.
🌾 Ohio Woodpeckers
Ohio has 7 regularly occurring woodpecker species. The red-bellied woodpecker is among the most common backyard birds statewide. Pileated woodpeckers are found in mature woodland throughout the state. The red-headed woodpecker, once abundant, has declined significantly but is still found in open woodland and forest edges. Downy and hairy woodpeckers are widespread year-round.
🌿 Minnesota Woodpeckers
Minnesota has one of the most diverse woodpecker populations in the Midwest with 9 species. The three-toed woodpecker and black-backed woodpecker — rare elsewhere — are found in the boreal forests of northern Minnesota. Pileated woodpeckers are common in the Boundary Waters region. The red-headed woodpecker breeds in the oak savannas of the south and west.
🌴 Florida Woodpeckers
Florida hosts 8 woodpecker species including the endemic red-cockaded woodpecker, listed as Near Threatened and found only in old-growth longleaf pine forests. The pileated woodpecker is common in northern Florida's mature forests. The red-bellied woodpecker is arguably the state's most common woodpecker. Year-round warm temperatures mean excellent woodpecker watching in any season.
🌻 Iowa Woodpeckers
Iowa has 7 woodpecker species with the downy, hairy, and red-bellied being the most common year-round residents. The red-headed woodpecker breeds in open woodland and is a sought-after species for Iowa birders. Yellow-bellied sapsuckers pass through on migration. The pileated woodpecker is found in mature river corridor forests in eastern Iowa.
🍑 Georgia Woodpeckers
Georgia has excellent woodpecker diversity with 8 species. The red-cockaded woodpecker inhabits the state's longleaf pine forests and is a conservation priority. Pileated woodpeckers are common throughout the state's mature forests. The red-headed woodpecker breeds in open pine woodland. Georgia's mild winters mean woodpeckers are active and visible year-round.
🌵 Texas Woodpeckers
Texas leads North America in woodpecker diversity with over 14 species due to its geographic range spanning eastern forest, western desert, and Hill Country habitats. The golden-fronted woodpecker replaces the red-bellied in central and western Texas. The ladder-backed woodpecker is common in arid scrub. East Texas shares most eastern species including the pileated woodpecker.
🦞 Maine Woodpeckers
Maine's boreal and mixed forests support 8 woodpecker species. The black-backed woodpecker is a specialty of burned spruce forests in northern Maine. The three-toed woodpecker also occurs in remote northern areas. Pileated woodpeckers are common throughout mature forest statewide. The yellow-bellied sapsucker breeds commonly and its characteristic sap wells are a familiar sight on birch trees.

7. How to Attract Woodpeckers to Your Property
If you want woodpeckers on your land, the key is habitat first and feeders second. Woodpeckers are territorial and need large areas of quality habitat — but the right setup can bring them in reliably.
Leave Dead Trees Standing
Snags are the single most important habitat feature for woodpeckers. If safe, leave dead and dying trees on your property. They provide both food (insects) and nesting cavities.
Offer Suet at Feeders
Suet is irresistible to most woodpecker species. Use a cage-style suet feeder hung on or near a tree trunk. Avoid suet blends with artificial colors or preservatives.
Add Peanuts & Peanut Butter
Peanuts in the shell, peanut pieces, and straight peanut butter (no salt or sugar) are highly attractive to red-bellied, red-headed, and downy woodpeckers especially.
Plant Native Trees
Native oaks, hickories, and fruit trees provide food and insect habitat. Avoid pesticide use — woodpeckers need healthy insect populations in your trees to thrive.

What do woodpeckers eat in winter?
In winter, woodpeckers shift away from insects toward stored food, berries, nuts, and suet. Many species have cached food in bark crevices during fall. At feeders, suet becomes their most important food source in cold months. Red-bellied woodpeckers rely heavily on acorns and other nuts they've stored in tree bark.
Why do woodpeckers peck on metal or my house?
When a woodpecker drums on metal gutters, chimney caps, or metal siding, it's communicating — not feeding. Metal produces the loudest possible drumming, which carries farther and makes the bird sound more impressive to rivals and potential mates. If it's drilling actual holes in wood siding, it has found insects inside and the insect problem needs addressing.
Are woodpeckers protected by law?
Yes — all woodpecker species in North America are protected under the federal Migratory Bird Treaty Act. It is illegal to harm, kill, capture, or destroy the nests of any woodpecker species. If woodpeckers are causing property damage, the legal solution is deterrents, not harm. Contact USDA Wildlife Services or your state wildlife agency for guidance.
How do I tell a downy from a hairy woodpecker?
Size is the best field mark — hairy woodpeckers are noticeably larger, about robin-sized, while downies are sparrow-sized. The clearest ID feature is bill length: the hairy's bill is nearly as long as its head; the downy's bill is much shorter relative to head size. Both have black and white plumage with males showing a red patch on the back of the head.
What is the largest woodpecker in North America?
The pileated woodpecker is the largest woodpecker in North America at 16–19 inches long with a wingspan up to 30 inches. It is roughly crow-sized with a distinctive flaming red crest. The ivory-billed woodpecker was larger but is almost certainly extinct — the last confirmed sighting was in the 1940s.
Do woodpeckers reuse their nesting holes?
Most woodpecker species excavate a new cavity each year, leaving their old holes for other wildlife. This makes woodpeckers what ecologists call "keystone species" — their cavity-excavating behavior creates irreplaceable nesting habitat for dozens of other species including owls, wood ducks, flying squirrels, and small mammals that cannot excavate their own cavities.
How long do woodpeckers live?
Woodpecker lifespan varies by species. Downy woodpeckers typically live 2–5 years in the wild, though the record is nearly 12 years. Larger species like the pileated woodpecker can live up to 12–15 years. Their main threats are predators (particularly Cooper's hawks and sharp-shinned hawks), window strikes, and habitat loss.
