Hairy Woodpecker

The Hairy Woodpecker is a widespread, medium-sized woodpecker native to North America. Characterized by its robust bill and striking black-and-white plumage, this diligent bird is a familiar sight in mature woodlands, parks, and suburban suet feeders. Highly energetic and louder than its smaller counterpart, the Downy Woodpecker, the Hairy Woodpecker plays a crucial ecological role by excavating cavities that are later used by secondary cavity nesters, and by keeping populations of wood-boring forest pests in check.

To successfully identify the Hairy Woodpecker, focus on size, bill proportion, and tail feathers:

• Size: Roughly the size of an American Robin. It is notably larger and more robust than the similar Downy Woodpecker.
• Bill: The bill is long, straight, and chisel-like, measuring nearly the same length as the depth of the head.
• Plumage: Strongly patterned in black and white. The back is mostly white, the wings are black with white spots, and the underparts are clean white. The head has black and white stripes.
• Gender Differences: Adult males feature a small, bright red patch on the back of the head (occiput), which females lack.
• Tail Feathers: The outer tail feathers are completely white and lack the black bars or spots typically seen on the Downy Woodpecker.

Similar Species

• Downy Woodpecker (Dryobates pubescens): The primary confusion species. The Downy is much smaller (sparrow-sized) with a stubby bill that is only about half the length of its head. Downy Woodpeckers also feature black spots on their white outer tail feathers.

Hairy Woodpeckers are widely distributed across North America, from the boreal forests of Canada and Alaska down to Central America. They are year-round residents throughout most of their range.

They prefer mature deciduous, coniferous, or mixed forests featuring large trees. Because of their need for substantial wood volume to search for large larvae, they are less common in young, regenerating forests. They also adapt well to wooded suburban areas, forest edges, orchards, and parks, provided there are mature trees available.

Foraging and Diet

Hairy Woodpeckers feed primarily on wood-boring beetle larvae, ants, caterpillars, and other forest insects. They are expert excavators, using their powerful bills to flake off tree bark and chip deep holes into dead wood to extract prey. They also consume seeds, nuts, and wild berries, and are frequent visitors to backyard suet and peanut feeders, especially in winter.

Vocalization and Communication

Their voice is sharp and commanding. The most common call is a high-pitched, explosive peek or pleek. When agitated, they emit a rapid, rattling whinny that maintains a relatively level pitch, unlike the descending whinny of the Downy Woodpecker. Both males and females drum loudly on resonant tree snags or metal surfaces to establish territories, producing a fast, continuous roll of 20–28 beats per second.

Nesting

Monogamous pairs begin excavating nesting cavities in early spring, usually choosing a dead tree or a dead branch of a living tree. The excavation takes up to three weeks, resulting in a gourd-shaped cavity with a clean, round entrance. A single clutch of 3 to 6 white eggs is laid directly on wood chips left at the bottom of the cavity. Both parents share incubation duties.
