Pygmy Nuthatch
Sitta pygmaea
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.
