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.
