1. General Description
The American goldfinch (Carduelis tristis) is a small bird in the finch family. It is the only species under the genus Carduelis to molt twice a year – in spring and autumn.
To prepare for the winter, the bird sheds all its bright feathers for duller ones. In spring, the goldfinch changes into a vibrant yellow for males and a yellowish brown for females, with its tail and wings staying the same.
The Iowa state bird name comes from the color of its dazzling yellow plumage that shines like gold. This color is more prominent on the male eastern goldfinch during the mating season.
The striking color in male goldfinches is meant to catch the attention of potential partners. In contrast, the female goldfinch’s feathers are more muted and in a dull shade of olive to brown on the body, tail, and wings.

Carl Linnaeus, the pioneer of natural taxonomy, first classified the American goldfinch into the genus Fringilla, where it was grouped with the common chaffinches and the bramblings.
Another naturalist, Mathurin Jacques Brisson established the genus Carduelis into the naming system for birds where the American Goldfinch and the European goldfinch were reclassified in 1760.
It was then regrouped to the genus Spinus which was added in the nomenclature in 1816 along with the species of siskins and other types of goldfinches such as the lesser goldfinch and Lawrence’s goldfinch.
3. Habitat and Distribution
American Goldfinches are found predominantly in North America, such as California, where weeds are abundant. You can spot them in the peripheral forests, open woodlands, meadows, residential areas, and backyards. They are rarely seen in the deep forests.
They are found all year in Iowa, no matter what the season. These birds may reach as far south as the woodlands of Florida during the winter season from December to February.
4. Diet and Feeding
Goldfinches are granivores, which means their diet is composed mostly of seeds. They have a penchant for sunflower seeds, elm seeds, and Niger seeds. They are mostly vegetarians – a unique trait among birds. Once in a blue moon, goldfinches, especially younger ones, might eat insects.
They usually feed during the day, and they also like to consume native milkweed. They like to hang around thistle plants for the seeds and use this plant’s fuzz to build their nest.
The American goldfinch is a social animal. They can be found in flocks during the non-breeding season. When it’s time for mating season, they spread out into smaller groups.
Both sexes are very territorial when they are building a nest. Males protect their territories against other male finches by attacking those who come near the nest.
6. Bird Call
The American goldfinch is known for its “po-ta-to-chip” bird call, but they have other varieties of vocalization. One notable example is a courtship call, which sounds like “tee-yee,” the male usually makes during the mating season.
Compared to other North American birds, the goldfinch tends to breed later in the year. Usually, their breeding season starts in June or July. The reason for this is the availability of seeds during the summer month.
Plants such as sunflowers, milkweed, coneflowers, and thistle are abundant in the late summer. The availability of the seeds from the flower during this season provides a favorable condition for the goldfinch to build its nest and have enough food supply for its babies.
