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 locally common in eastern WashingtonÕs large ponds and lakes at lower elevations throughout the Columbia basin and Okanogan valley.

Good habitats in core areas of use were larger lakes or reservoirs in the Central Arid Steppe, Big Sage/Fescue, Three-tip Sage, Palouse, Ponderosa Pine near Turnbull in Spokane County, and throughout the channeled scablands. However, the Eared Grebe is apparently not present in much of the western Columbia basin especially eastern Yakima and Kittitat Counties.

The exclusion of this species from southeastern Washington is based on a lack of records. BBA data are scarce, but the Eared Grebe probably nests in many large ponds and lakes throughout southern and southeastern Washington. Eared Grebes have a high tolerance of salinity which allows them to nest in most eastern Washington water bodies. Developing vegetation is necessary for nesting as this GrebeÕs nest is a floating vegetation mat in shallow water. Like other grebes, this species is not found nesting in flowing rivers.
