Evening Grosbeak

Scientific Name: Coccothraustes Vespertinus

Population Estimate: 6M

Range / Habitat: A North American species, the evening grosbeak is widespread across Canada and the United States, reaching as far south as Mexico. The breeding range of C. v. brooksi stretches south from western Canada to California, Arizona and New Mexico in the U.S., while C. v. montanus occurs from southeast Arizona into parts of Mexico. C. v. vespertinus has a more easterly distribution, breeding from central and eastern Canada south to northern Minnesota, Michigan, Wisconsin, New York, Vermont and Massachusetts in the U.S.

Field Notes: The Evening Grosbeak (Coccothraustes vespertinus) is a large finch. In the past, it was treated in a genus of its own as Hesperiphona vespertina. The male evening grosbeak is quite distinctive, being mostly bright yellow with a brownish-black head, neck and throat, a black tail and wings, and large white wing patches. The dark head is marked by a conspicuous bright yellow forehead and yellow stripes above the eyes. Outside of the breeding season, the heavy bill is off-white or buff, but it becomes pale greenish-yellow in spring. The evening grosbeak’s legs and feet are fleshy pink to brown.
