The Pygmy Nuthatch is the smallest nuthatch in North America and often the most social — flocks of 10–15 birds roost communally in a single tree cavity in winter, huddling together and entering torpor to survive cold nights. Cooperative helpers assist breeding pairs. It gives a rapid, high-pitched 'pee-dee-dee' call from ponderosa pine tops.
