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 a rare and local breeder in freshwater ponds and lake in eastern Washington. There are no recent breeding records of this type of grebe.

None of its habitats were modeled.

Horned Grebes prefer lakes with low salinity, a factor which limits their utilization of eastern Washington water bodies. The limited breeding season records are likely non-breeders. Within the BBA period, no nests were reported. Historically, this species has occasionally bred in eastern Washington at Turnbull National Wildlife Refuge in Spokane County and Rock Lake in Whitman County.
