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 uncommon in relatively undisturbed shrub-steppe habitats of the central Columbia Basin. It prefers alternating patches of shrub-steppe and grassy areas, as opposed to contiguous shrub-steppe areas.

Good habitat in core zones included shrub and shrub savanna in the Big Sage/Fescue, Central Arid Steppe, Canyon Grassland, Bitterbrush, and Three-tip Sage zones.

Throughout all of eastern Washington, Loggerhead Shrikes were undoubtedly more widespread prior to the massive conversion of shrub-steppe habitats to agriculture. Despite this, and the dramatic decline of this species in the eastern United States, unpublished Breeding Bird Survey data show slight population increases from l966 to l991. In neighboring Oregon, this species has had a 25-year declining trend. Some of the data for this map were provided by the Washington Department of Fish and Wildlife.
