Brown-headed Nuthatch
At a Glance
A small nuthatch of the southeastern pine forests. Found in pairs or family groups all year, it is often heard before it is seen; the birds call to each other constantly as they busily clamber about on the branches. In winter, small groups of Brown-headed Nuthatches often join mixed foraging flocks including chickadees, woodpeckers, and Pine Warblers.

Behavior
Eggs
Usually 4-6, sometimes 3-7. White, marked with reddish-brown. Typically lays 4 or 5 eggs in Florida, 5 or 6 elsewhere. Female incubates, about 14 days. Male brings food to female during incubation; male roosts in nest with female and eggs at night.
Young
Both parents feed young (and so does additional "helper" at some nests). Young leave nest in 18-19 days. Usually 1 brood per year, rarely 2.
Feeding Behavior
Forages mainly on trunk and large limbs of pines, also on higher branches and twigs. Males may forage lower than females, descending on trunks almost to ground. May use a chip of bark as a tool to pry off other pieces of bark while searching for insects. Sometimes catches flying insects in the air. May store seeds in bark crevices.
Diet
Mostly insects and seeds. Eats more insects and spiders in summer, more seeds (mainly pine seeds) in winter.
Nesting
Some nests aided by "helper," an additional male that brings food to female on nest, also to young after eggs hatch. Nest: Both sexes help excavate nest cavity in dead tree, usually in pine, sometimes in deciduous tree or fence post near pine forest. Pair may begin several excavations before completing one for nest. Will also use birdhouses, old woodpecker holes; sometimes competes for nest sites with Eastern Bluebird. Nest sites average about 5' above ground, rarely more than 15' high. Nest in cavity made of grass, bark fibers, hair, feathers, also "wings" of pine seeds.
Climate Vulnerability
Conservation Status
Probably the least numerous nuthatch in North America. Has lost ground in some areas because of habitat loss, but still common where southern pine forest exists.
