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.

Local and uncommon in very high alpine habitats. Normally above 6500 feet in the Olympics and above 6000 feet in the Cascades. Foraging occurs on alpine meadows, ice, snow, and rocks.

Good habitat in core areas included alpine meadows, parkland, rocks,and ice in Alpine/Parkland and Permanent Ice/Snow zones.

This species was formerly considered conspecific (of the same species) with other North American and Old World forms, but recognized as a full species in l993. It formerly bred on Mount St. Helens, but there have been no records since the l980's. In the Olympics, Rosy-finches are not widespread breeders and are limited to the highest peaks: Mount Olympus, Mount Carrie, Mount Deception and Mount Anderson. In the Cascades, this species is most common in suitable habitat north of Snoqualmie Pass. Primary productivity is low, but so is competition for resources. Rosy-finches are certainly more widespread than is indicated by the low number of records reported in the Breeding Bird Atlas; little of their breeding range is readily accessible.
