Breeding Range Map
The Western Pipistrelle is at the northern limit of its range in Washington. Washington records for this tiny bat are associated with deep river canyons and large water bodies in arid terrain. It probably forages over many habitats as long as cliffs are nearby for day roosts. Its primary night roost may be sagebrush.
The range of this bat was limited to within a few miles of the largest rivers through the central and eastern Columbia Basin (the Columbia and Snake Rivers and the lakes and rivers along the Grand Coulee), with its northern range limit in southern Okanogan County. The Central Arid Steppe and Canyon Grassland zones were core, all others were excluded. All habitats were good except agriculture, which was adequate. All development was excluded as habitat.
