Pygmy Nuthatch

About the Pygmy Nuthatch

The pygmy nuthatch (Sitta pygmaea) is a tiny songbird, native to western North America. The pygmy nuthatch is 9–11 cm (3.5–4.3 in) long and with a wingspan of 19.7 cm (7.8 in), and weighs 9.3–11.4 g (0.33–0.40 oz). It ranges from southern British Columbia south through various discontinuous parts of the western U.S. (northwest U.S., Sierra Nevada range, southern Rockies, etc.), to central Mexico. It is usually found in pines (especially ponderosa pine), douglas-fir, and other conifers. Pygmy nuthatches clamber acrobatically in the foliage of these trees, feeding on insects and seeds; less often they creep along limbs or the trunk like bigger nuthatches.

Pygmy nuthatches nest in cavities in dead stubs of conifers, lining the bottom of the cavity with pine cone scales, plant fibers, and other soft plant and animal materials. They may fill cracks or crevices around the entrance with fur; the function of this behavior is unknown. The female lays 4–9 eggs, which are white with fine reddish-brown spotting. She does most of the incubation, which lasts about 16 days. The young leave the nest about 22 days after hatching.
