American Goldfinch: Summer vs. Winter Plumage & What They Eat

Every fall, someone asks: "Where did all my goldfinches go?" Usually, the answer is that they never left. American Goldfinches trade their lemon-yellow summer feathers for a soft olive-brown winter coat, and they're easy to overlook at the feeder. Here's how to recognize goldfinches in every season.

Quick ID

  • Size: about 4.5–5 inches — small, with a short, conical pinkish bill.
  • Wings: black (male) or blackish-brown (female and winter birds) with crisp white or buffy wing bars in every plumage.
  • Tail: short and notched, with white under the tail.
  • Flight: bouncy and roller-coaster-like, often with a cheerful call that sounds like po-ta-to-chip.

Plumage through the year

Bird Spring–summer Fall–winter
Male Brilliant lemon yellow; black forehead cap; black wings with white bars Olive-brown to buffy; yellowish throat; black wings with buffy bars; no cap
Female Duller yellow below, olive above; no black cap Grayish-brown, hint of yellow on throat
Juvenile (late summer) Warm brown with cinnamon-buff wing bars

Goldfinches molt their body feathers twice a year: once in late summer and fall, and again in late winter and spring. Watch your feeder in March and April and you'll see males looking patchy and mottled, like they're halfway through changing clothes — because they are.

The late bloomers of nesting season

American Goldfinches nest later than almost any other North American songbird, usually starting in late June or July and carrying on into September. The timing lines up with the peak of seeding thistles, milkweed and other plants: goldfinches line their nests with soft plant down and feed their young regurgitated seeds. They are among the most strictly vegetarian songbirds on the continent.

What goldfinches eat

  • Nyjer (thistle) seed in a fine-mesh or small-port tube feeder.
  • Sunflower hearts (hulled chips) — no shells to crack.
  • Garden seedheads: coneflowers, black-eyed Susans, sunflowers, asters, zinnias and native thistles. Leave the seedheads standing into fall.

Nyjer goes stale and can spoil when wet, so buy small amounts and keep feeders dry. If goldfinches suddenly ignore a full feeder, the seed is the first thing to check.

Look-alikes

  • Lesser Goldfinch (West and Southwest): males have dark green or black backs, and yellow undertail.
  • Pine Siskin: brown and heavily streaked with yellow wing flashes; often mixed into winter goldfinch flocks.
  • Yellow Warbler: all-yellow with a thin bill and no black cap or black wings; eats insects, not seed.

Songs and calls

Goldfinches are chatty. The flight call, given with each bounce of their roller-coaster flight, is often remembered as po-ta-to-chip or per-chic-o-ree. Their song is a long, lively series of twitters and warbles, and males sometimes sing while flying in slow circles during courtship. In late summer, listen for begging young: a persistent, wheezy chee-wee from fledglings following their parents through weed patches.

Behavior at the feeder

Goldfinches are social birds that travel in flocks for most of the year, especially in winter, when flocks may include Pine Siskins and, in some years, redpolls from the far north. They are agile feeders that cling to swaying seedheads and can feed upside down. At feeders they tend to tolerate one another better than many species, so a long tube feeder can host a whole row of them.

They also have a clever defense against cowbirds, which lay eggs in other birds' nests: cowbird chicks raised by goldfinches rarely survive, likely because a strictly seed-based diet doesn't suit them.

Turn your garden into a goldfinch café

Want goldfinches without a feeder? Plant a sunny bed of native seed producers and leave the heads standing:

Plant When goldfinches eat it
Purple coneflower Late summer into winter
Black-eyed Susan Late summer and fall
Native sunflowers Late summer and fall
Asters and goldenrods Fall
Native thistles Mid-summer (also a source of nest-lining down)

Avoid treating the bed with pesticides, and be patient: goldfinches often find a new seed source within days of it ripening.

A goldfinch year at a glance

Season What you'll see What to offer
Late winter–spring Patchy yellow as birds molt into breeding plumage Nyjer and sunflower chips
Early summer Bright yellow males, flocks still at feeders Nyjer; a shallow bird bath
Mid–late summer Nesting begins as thistle and other plants go to seed Leave coneflowers and sunflowers standing
Fall–winter Dull olive-brown birds, often in mixed flocks Keep feeders filled and dry

Tip: nyjer goes stale and can mold if it sits wet. Fill tube or sock feeders only partway in damp weather, and shake out clumped seed.

Telling male from female in winter

Winter goldfinches can look nearly identical, but a few clues help. Males usually keep jet-black wings with bold white bars, and many show a hint of yellow at the throat. Females have browner-black wings with buffier wing bars. In spring, males start showing bright yellow patches before females do, so a "patchy" bird in March is often a male mid-molt. American Goldfinches are among the few North American songbirds that molt their body feathers twice a year, which is why they change so dramatically.

FAQ

Where do goldfinches go in winter?

Across much of the US they stay put — they're just wearing drab winter plumage. Birds from the far north do shift south.

Why are my goldfinches turning brown?

That's their normal fall molt. The bright yellow returns in spring.

Which states have the goldfinch as state bird?

Iowa, New Jersey and Washington.

What is the best feeder for goldfinches?

A tube or mesh feeder stocked with fresh nyjer or sunflower hearts. They're comfortable clinging, even upside down.
