The American Goldfinch (Spinus tristis, previously Carduelis tristis) is an American songbird in the finch family. Due to its physical resemblance to the Canary, the American Goldfinch is often called "Wild Canary".

Description

American Goldfinches are tiny, 5 in (13 cm) long, yellowish finches with tiny, thin bills adapted for extracting seeds from tight spaces. The male American goldfinch undergoes a dramatic transformation each spring, exchanging khaki-brown body plumage, similar to the female's, for brilliant yellow with black wings, tail, and forehead. Both sexes have a white rump and white or yellowish wing bars. The juvenile is similar to the adult female.

Sounds

High pitched trills and twitters, along with plaintive chirps.

Behaviour

These birds are often seen in flocks of up to 20 and are common backyard birds throughout most of their range.

Diet

Seeds of thistles (most commonly nyjer), dandelions, and other members of the sunflower family, grass seeds, small tree seeds (birch, alder), buds, young leaves, small fruits, insects. This finch is a common seed feeder visitor.

Breeding

Nesting occurs in late summer. The female builds a cup-shaped nest lined with thistle down and then lays 4-6 pale blue eggs that she incubates for 10-12 days while the male feeds her. The chicks are fed by both parents, and fledge within 11-17 days. One annual brood.

Distribution and habitat

The American Goldfinch inhabits weedy open fields and roadsides, particularly with sunflowers or thistles, woodland edges, all throughout the contiguous United States as well as in parts of northern Mexico and southern Canada.
