Weedy fields, open floodplains, and other overgrown areas, particularly with sunflower, aster, and thistle plants for food and some shrubs and trees for nesting. Goldfinches are also common in suburbs, parks, and backyards.Back to top
Goldfinches eat seeds almost exclusively. Main types include seeds from composite plants (in the family Asteraceae: sunflowers, thistle, asters, etc.), grasses, and trees such as alder, birch, western red cedar, and elm. At feeders prefers nyjer and sunflower.Back to top
Male and female move around together to choose a suitable nest site. The female builds the nest, usually in a shrub or sapling in a fairly open setting rather than in forest interior. The nest is often built high in a shrub, where two or three vertical branches join; usually shaded by clusters of leaves or needles from above, but often open and visible from below.
The nest is an open cup of rootlets and plant fibers lined with plant down, often woven so tightly that it can hold water. The female lashes the foundation to supporting branches using spider silk, and makes a downy lining often using the fluffy “pappus” material taken from the same types of seedheads that goldfinches so commonly feed on. It takes the female about 6 days to build the nest. The finished nest is about 3 inches across on the outside and 2-4.5 inches high.

American Goldfinches are active, acrobatic finches that balance on the seedheads of thistles, dandelions, and other plants to pluck seeds. They have a bouncy flight during which they frequently make their po-ta-to-chip calls. Although males sing exuberantly during spring, pairs do not nest until mid-summer, when thistles and other weeds have gone to seed. Goldfinches do not join other songbirds mobbing predators.Back to top
American Goldfinch are numerous, though populations experienced a small decline between 1966 and 2014, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 42 million, with 91% spending some part of the year in the U.S., 33% in Canada, and 6% wintering in Mexico. They rate a 6 out of 20 on the Continental Concern Score and are not on the 2014 State of the Birds Watch List. Back to top
To encourage goldfinches into your yard, plant native thistles and other composite plants, as well as native milkweed. Almost any kind of bird feeder may attract American Goldfinches, including hopper, platform, and hanging feeders, and these birds don’t mind feeders that sway in the wind. You’ll also find American Goldfinches are happy to feed on the ground below feeders, eating spilled seeds. They’re most attracted to sunflower seed and nyjer. Find out more about what this bird likes to eat and what feeder is best by using the ProjectFeeder Watch's Common Feeder Birds bird list.
To protect American Goldfinches from contagious diseases at feeders, keep the ground well-raked. For more information about keeping feeders clean, see Project FeederWatch’s “Safe Feeding Environment”.
For more information about what to do if you see a sick bird at your feeder, see Project Feeder Watch’s “Diseased Birds”.Back to top
