Lesser Goldfinch (Spinus psaltria) Is a small songbird, only 11 cm (4.5 inches) long. It is smaller and darker billed than the American Goldfinch. Both male and female have white wing patch at base of primaries. Adult male has and entire black crown. Underside, starting at lower bill, is bright yellow. Adult females and juveniles have dull yellow underside. There are several subspecies. Two color patterns occur in the United States. Males in some areas may be either green-backed or black-backed. Lesser Goldfinches gather in scrubby oak, cottonwood, and willow habitats of the western U.S., or visit suburban gardens for seeds and water. These finches primarily eat the seeds of plants. In bird feeders, they especially enjoy Nyger seeds.

COMPARED TO

American Goldfinch (Spinus tristis) Larger and lighter billed than Lesser Goldfinch. It is a small, migratory songbird that displays sexual dichromatism: the male is a vibrant yellow in the summer and an olive color during the winter, while the female is a dull yellow-brown shade which brightens only slightly during the summer. The male displays brightly colored plumage during the breeding season to attract a mate.

COMPARED TO

Lawrence's Goldfinch (Spinus lawrencei) is a small, migratory songbird in the Siskins and New World Goldfinches (Spinus) genus. It is "unique among goldfinches because of its mostly gray body. Male has black forehead and throat, yellow breast, and complex black and yellow pattern on wings. Female is duller. It is found in open grassy woodland. It is uncommon, but sometimes travels in large flocks, especially in fall and winter. Highly erratic, moves around a lot from year-to-year; difficult to track down with much reliability. Feeds on seeds. Sometimes visits feeders."
