Meet the American Goldfinch

The American Goldfinch is a small, colorful finch that is a familiar visitor at backyard bird feeders across North America. It is also the official state bird of New Jersey, Iowa, and Washington.

During spring and summer, male American Goldfinches are especially striking, with brilliant yellow plumage contrasted by a shiny black forehead and wings with touches of white. Females and winter birds are much more subdued in color, but their distinctive shape and markings still make them easy to recognize.

American Goldfinches commonly gather in flocks with Pine Siskins and Redpolls. During molting, their feathers can become surprisingly patchy, giving them a very different appearance for a short period.

How to Identify Male and Female American Goldfinches

The easiest way to distinguish American Goldfinches is to look at their plumage and body shape.

Male American Goldfinch

In spring and summer, adult males are typically bright yellow with a shiny black forehead and black wings. Small areas of white can also be seen on the wings and tail.

Their vivid breeding plumage makes them one of the most recognizable backyard finches.

Female American Goldfinch

Females are considerably less colorful. They are generally dull yellow, olive, or brownish, with darker wings and subtle markings.

Winter males also lose much of their brilliant yellow appearance and can look more similar to females.

Quick Identification Guide

Regardless of season, the conical bill, pointed notched tail, wingbars, and lack of heavy streaking are useful clues when identifying an American Goldfinch.

How to Attract American Goldfinches to Your Backyard

American Goldfinches are easy to attract because they will use many different types of feeders. Hopper, platform, and hanging feeders can all work, and goldfinches are not particularly bothered when a feeder moves in the wind.

Their favorite feeder foods include:

• Sunflower seeds
• Nyjer seeds

They will also happily feed on the ground beneath feeders, picking up seeds that have fallen onto the ground.

For a more natural food source, plant native thistles, other composite plants, and native milkweed. These plants can provide seeds that American Goldfinches naturally seek out.

Why Do American Goldfinches Change Color?

American Goldfinches are unusual among finches because they molt their body feathers twice every year—once in late winter and again in late summer.

This seasonal molt explains the dramatic difference between their bright spring appearance and their much duller winter plumage.

The return of brilliant yellow feathers in males each spring is one of the most noticeable signs that warmer weather is approaching.

American Goldfinches Nest Later Than Most Birds

American Goldfinches have a surprisingly late breeding season compared with many other North American birds. They typically wait until June or July to begin nesting.

One reason is food availability. By this time, milkweed, thistles, and other plants have produced the fibrous seeds that goldfinches use when building their nests and feeding their young.

This close connection to seed-producing plants makes native vegetation especially valuable for goldfinches during the breeding season.

One of the Strictest Vegetarian Birds

American Goldfinches have an unusual diet compared with many other birds. They are among the strictest vegetarians in the bird world and rely almost entirely on plant foods.

They may accidentally swallow an insect while feeding, but insects do not form a normal part of their diet.

This plant-based diet also affects what they feed their young.

Why Brown-Headed Cowbird Chicks Struggle in Goldfinch Nests

Brown-headed Cowbirds sometimes lay their eggs in the nests of other bird species. A cowbird egg placed in an American Goldfinch nest may hatch successfully, but the young cowbird usually survives for only about three days.

The main problem is food. Goldfinches feed their nestlings an almost entirely seed-based diet, which does not provide the type of nutrition a young cowbird needs to survive.

Where Do American Goldfinches Go in Winter?

American Goldfinches generally move southward during winter. Their movements appear to be associated with regions where the average minimum temperature in January remains no colder than 0°F (-18°C).

As temperatures drop, many goldfinches head toward warmer areas where food remains more readily available.

Goldfinches May Recognize Their Partners by Their Calls

Paired American Goldfinches produce flight calls that are remarkably similar to one another. Researchers have suggested that these nearly identical calls may help goldfinches recognize members of different pairs.

This subtle form of vocal communication provides another example of the social complexity of these small finches.

How Long Do American Goldfinches Live?

American Goldfinches can survive for many years in the wild.

The oldest known American Goldfinch was 10 years and 9 months old when it was recaptured and released during a bird-banding operation in Maryland.

Why American Goldfinches Are Backyard Favorites

From their brilliant yellow spring plumage to their preference for sunflower and nyjer seeds, American Goldfinches are a favorite among backyard birdwatchers.

Their dramatic seasonal color changes, nearly vegetarian diet, late breeding season, and close relationship with native seed-producing plants make them especially fascinating to observe. A few well-placed feeders combined with native thistles, milkweed, and other plants can turn your backyard into an attractive year-round stop for these beautiful little finches.
