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.

This species is fairly common in freshwater marshes and wet meadows on both sides of the Cascades. They were limited to lowlands in western Washington where they are less common, but they are more common in eastern Washington, breeding up to 4000 feet. Also occurs in lesser numbers in brackish marshes. They will utilize wet areas in agricultural fields.

The core areas of use were all east-side zones below Subalpine Fir and, on the west side, Puget Sound Douglas-fir, Woodland Prairie Mosaic, and locally in Western Hemlock. Fresh water/wetlands were good and estuarine grasslands were adequate. Irrigated fields in steppe, Ponderosa Pine, and Oak zones, and all agricultural fields in other forested zones were included knowing there may be smaller pockets of habitat suitable for the Sora if the appropriate habitat (wetlands) below our mapping resolution was present within the larger mapped habitat.

Soras are often found in the company of Virginia Rails at lower elevations, though Soras can occur in habitats with less water and at higher elevations than Virginia Rails. They can occupy marshes of many different types, including cattail-dominated sites at low elevations, such as at the Toppenish National Wildlife Refuge, and moist sedge meadows in cooler, higher areas, such as near Mount Bonaparte.
