American Goldfinch - Spinus tristisAmerican Goldfinches are a common sight at residential bird feeders in the United States, and are well known for their "per-chickory" calls.  They are the only finch species that molt their feathers twice in a year. Males begin molting to their bright yellow breeding plumage in early spring, and even the females become brighter and more colorful for the summer breeding season. Both males and females are much less colorful during the winter months.  American Goldfinch are also unusual in that they nest very late compared to most migratory songbirds, typically not starting to nest until mid-summer.  The delay in summer nesting is thought to coincide with availability of seeds on which American Goldfinch depend, particularly milkweed and thistle.

Habitat:

 Roadsides, residential areas, brushy fields, forest edges, and orchards.

Diet:

Mostly seeds.  Also buds, sap, and only on extremely rare situations, insects.

Behavior:

Often forages in small flocks, clambering and climbing over vegetation and seed heads.  During the start of the breeding season, males can be seen giving a flight display, singing while they fly.

Nesting:

July and August.  The nest of an American Goldfinch is a small cup built of grasses and other plant fibers, spider webs, and downy material from thistles and other plants.  The female lays between 3 and 7 eggs, and she alone incubates them.  When the eggs hatch, both parents help to feed the young.  The young leave the nest after about 2 weeks.

Migration:

Irregular resident in the winter, with large numbers staying one year and very few the next.

Similar Species:

Lesser Goldfinch, Lawrence's Goldfinch. Plumage and bill differences make it possible to easily distinguish between the species. In breeding plumage, American Goldfinches are the only goldfinch species with an orange bill.  Females are generally more difficult to differentiate for the three species, but the white undertail coverts of a female contrast with the yellow of a Lesser Goldfinch, while the Lawrence's Goldfinch has yellow wing bars instead of the white on an American and Lesser Goldfinch.  Click here for a page that describes the differences between American, Lesser, and Lawrence's Goldfinch.

Conservation Status:

Widespread and common, with local fluctuations in populations but no widespread trend.  The IUCN lists the American Goldfinch as a species of "Least Concern".

Bird Feeders:

 Will attend feeders for thistle (niger) and sunflower seeds.
