Goldfinches are common in grassy meadows and weedy areas where they feed on thistle and other seeds. The male American Goldfinch is easily recognized by its bright yellow color and black and white striped wings, whereas the females have a dull, olive color. Their plumage changes to a muted olive green or brown color in winter. Goldfinches are very acrobatic and can land on a grass or thistle stalk to feed. They nest mid- summer once their main food source, weed seeds, are readily available. Typically goldfinches produce one brood of chicks a year. Goldfinches are a year round resident in Teton Valley and are easily attracted to bird feeders, preferring sunflower and nyger (thistle) seed. To attract goldfinches to your yard, try hanging a thistle feeder or thistle sock. Feeders should be placed near other small trees or shrubs so birds have safe cover while they eat.
