Breeding Range Map
The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

The presence of this species is uncommon to common in dry, open Ponderosa Pine forests at low elevations throughout eastern Washington. It is local in the Blue Mountains.

Core zones were Ponderosa Pine, Oak, and steppe zones at the edges of the Columbia Basin, and it occurred peripherally in Interior Douglas-fir. In steppe zones mixed and conifer forests and tree savanna were good habitats. Low density development, hardwood forests, and wetlands were adequate. In the Oak and Ponderosa Pine zones, tree savanna and open-canopy canopy mixed and conifer forests were good; low-density development, other forests, wetlands, and pasture were adequate. The Interior Douglas-fir zone was treated like the Ponderosa Pine zone, except that closed forests were excluded.

Few species have such a predictable distribution as the Pygmy Nuthatch. They are very closely tied to Ponderosa Pine, and are rarely found far from it. In northeastern Washington, they can be found along major river valleys, and rarely farther up in the Interior Douglas-fir zone. Curiously, they are very local in the Blue Mountains, despite the widespread presence of Ponderosa Pine there.
