General: White-breasted Nuthatches are agile birds that can typically be seen walking along a tree and even hanging upside down below a tree branch as it searches for insects and seeds.

White-breasted Nuthatches are common around bird feeders often taking seeds, nuts or pecking at suet. In winter, White-breasted Nuthatches join mixed flocks with chickadees and tufted titmice.

White-breasted Nuthatches typically build nests in natural tree cavities or abandoned woodpecker holes. The eggs are about .7" long are white with light red-brown speckles. The chicks hatch in approximately 13 - 14 days and fledge in about another 14 days.
