A beloved backyard bird that frequents bird-feeders, the American goldfinch can be found in all the lower 48 states at some point in the year. This acrobatic finch with its signature bouncy flight is easy to spot in open meadows, fields and parks as it forages for food. One of the strictest vegetarians in the bird world, the American goldfinch lives almost exclusively on seeds.
