Brown-headed Nuthatch

The Brown-headed Nuthatch is a small, active nuthatch endemic to the pine forests of the southeastern United States, with a warm brown cap, blue-gray back, and pale grayish-white underparts. It shares the compact body and straight, chisel-like bill typical of nuthatches, and is closely tied to mature pine woodlands, particularly longleaf pine ecosystems that have declined significantly across its range.

This species is notable for being one of the very few North American birds documented to use tools: individuals have been observed holding a loose flake of bark in the bill and using it as a lever to pry up other bark scales in search of hidden insects.

Key Field Marks

• Small size, warm brown cap extending down to the eye
• Blue-gray back and wings
• Pale grayish-white underparts
• Small pale spot on the nape
• Short tail, straight thin bill

Similar Species

• Pygmy Nuthatch: very similar in size and structure but occurs in western pine forests with essentially no range overlap; slightly grayer-brown cap.
• Red-breasted Nuthatch: shows a bold black eye stripe and rusty underparts, quite different from the plain-faced Brown-headed Nuthatch.
• White-breasted Nuthatch: larger, with a solid black cap and bright white face.

Habitat

Brown-headed Nuthatches are closely tied to mature pine forest, especially longleaf, loblolly, and shortleaf pine stands with open understory maintained historically by periodic fire.

Range

The species is found throughout the coastal plain and piedmont of the southeastern United States, from Virginia and Maryland south through Florida and west to eastern Texas and Oklahoma.

Migration

Brown-headed Nuthatches are non-migratory residents, remaining within pine forest habitat year-round and generally not wandering far from their home range.

Behavior

Active and social, Brown-headed Nuthatches forage in small flocks or family groups, moving rapidly over bark and pine needle clusters, often hanging upside down in typical nuthatch fashion.

Voice

The call is a distinctive, high-pitched, squeaky chatter often likened to a rubber duck or dog toy — a useful and memorable way to locate the species by ear.

Feeding

Diet includes insects and spiders gleaned from bark and pine needles, along with pine seeds, which are cached in bark crevices for later retrieval; the species is notable for using bark flakes as tools to pry off other bark in search of prey.

Nesting

Nests are built in cavities excavated in dead or decaying pine snags, sometimes assisted by helper birds at the nest, similar to the cooperative breeding seen in the closely related Pygmy Nuthatch. Clutches typically number 5-6 eggs.
