Finches (Fringillidae)

Evening Grosbeak (Hesperiphona vespertina) - HBW 15, p. 615

French: Gros-bec errant German: Abendkernbeißer Spanish: Picogordo Vespertino

Taxonomy: Fringilla vespertina W. Cooper, 1825, Sault Sainte Marie, Michigan, USA.
Geographical variation slight. Other proposed races in USA are relatively somewhat shorter-billed californica (described from Crane Flat, in Yosemite National Park, in east California) and narrow-billed warreni (from Bear Creek, near Colorado Springs, in C Colorado), both a little paler than, but synonymized with, brooksi; some vocal differences apparent, however, and further research required. In Mexico, proposed race mexicana (from Las Vigas, in Veracruz), is considered inseparable from montana. Three subspecies recognized.
