American Goldfinch,
common name for a small songbird found year-round throughout the United States and Canada,
and during the winter in northern Mexico.
-
A member of the
finch family, the
American goldfinch is one of the most abundant birds in the United States, common to
parks, farms, and suburban gardens.
-
It is the state bird of Iowa, New Jersey, and
Washington.
-
Males and females, which are
both about 13 cm (about 5 in) long, have very different plumage patterns.
-
In the spring
the male has bright yellow plumage with a black cap, while the female has grayish-yellow
plumage without a black cap.
-
During the winter both sexes assume a brownish plumage. With
its broad, strong beak, the American goldfinch is able to eat a variety of hard seeds.
-
It
feeds primarily on thistles and weeds, but will eat insects when available.
-
The male goldfinch waits until
it has its bright spring plumage before courting the female with song while he flies in
front of her.
-
The American goldfinch nests later than most other birds to take advantage
of abundant ripe thistle seeds to feed its young.
-
During the late summer, the female
builds a small nest in a shrub or tree and lays four to six bluish-white eggs.
-
The male
feeds the female during the two weeks that she incubates, or warms, the eggs, and both
parents feed the young.
-
The young leave the nest about two weeks after hatching and spend
the fall following their parents as they feed in flocks with other goldfinches.
