Pygmy Nuthatch — size comparison — facts and sources
The pygmy nuthatch is associated with pine forests of western North America. It particularly selects long-needled stands, feeding on trunks, branches and cones. It is sociable, and outside breeding several families often join into active groups moving through a shared feeding area.
During rearing it eats mainly insects, spiders and other invertebrates. Pine seeds are important in winter in some regions. Throughout the year it may hide seeds beneath bark, using stores later when fresh food is harder to obtain.
It nests in a cavity or nest box. Some pairs receive help from relatives, often males from earlier broods, supplying food and defending the nest. On cold nights many individuals rest together in a sheltered hollow, and communal roosting helps them survive the cold.
