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.

Locally common in irigated hayfields in northeastern Washington and at Toppenish National Wildlife Refuge in south-central Washington (Yakima County).

Good habitat in core areas of use included riparian wetlands with emerfgent vegetation, rivers, and irrigated agriculture, limited to areas with known colonies.

Bobolinks nest in loose "colonies" in Washington which is the westernmost end of their known distribution. The colony at Toppenish Nainal Wildlife Refuge is probably the westernmost Bobolink colony in North America. It was the first in Washington with confirmed nesting activity, with eggs discovered in 1977.
