The American Goldfinch is one of the last birds to breed in the summer, from late July to September. Goldfinches usually only produce one brood per season of four to six eggs. The female builds the nest, and incubates the eggs by herself. The eggs hatch in about 13 to 14 days, with the young staying in the nest another 14 days. The male does help the female in raising the young.

Nests are built in trees or shrubs 15 to 40 feet above the ground the average being 15 to 17 feet. These birds will not use old nests and will not use nesting boxes or platforms. Nests are often lined with thistle down and timing of breeding is based on the availability of thistle down.

Sounds:

Canary like. When the bird flies its unique up and down flight, it often sings t—dee-di-di.
