During the mating season, Pygmy Nuthatches eat 60-85% of insects, including beetles, wasps, ants, and caterpillars. Their diet also includes pine tree seeds and other plant components. Pygmy Nuthatches use their bills to probe wood crevices and remove the bark to reveal insects hidden inside.


Pygmy Nuthatches enjoy Ponderosa, Monterey, and Jeffrey pines. They thrive in undisturbed old-growth woods with plenty of dead pines. Pygmy Nuthatches inhabit slopes and mountains up to the tree line where old-growth pine trees are abundant.


Pygmy Nuthatches walk, hop, or climb rapidly. They always climb up or down a tree headfirst. Pygmy Nuthatches rarely fly over long distances; they usually fly between trees to find food. A Pygmy nuthatch mating couple inhabits a territory all year but defends it only during the breeding season. Pygmy Nuthatches bathe in rainwater and melting snow ponds, and preen and allopreening in flocks.
