Goldfinch Winter Plumage: Why They Turn Drab

American goldfinches turn drab every fall because they molt out of their bright breeding feathers and into a muted winter coat. From roughly late fall to early spring, both males and females are a soft olive-brown or buffy tan, with a faint yellow wash on the face and throat and black or dark wings crossed by bold pale bars. The birds at your feeder have not left; most of them have just changed clothes.

They switch back in spring. By May, males are lemon yellow again with a black cap, and females are a warmer olive-yellow.

What goldfinch winter plumage looks like

A winter goldfinch is a small, pale, unstreaked finch. That last word matters: the body has no streaks at all, which separates it from most of the brown birds it might be confused with.

• Body: olive-brown to grayish-buff above, paler buff below, often with a yellowish tinge on the face and throat.
• Wings: dark, with two bold wing bars, white in males and buffier in females.
• Undertail: white.
• Bill: small and cone-shaped; the orange bill of summer turns dull in winter.
• Size: about 4.5 to 5 inches, smaller than a House Finch.

Males are still easy to pick out if you look at the wings. A winter male has jet-black wings with crisp white bars and a yellowish patch at the shoulder. A winter female has browner, duskier wings, buffier bars and no yellow shoulder. The full breakdown is in goldfinch male vs female.

The goldfinch molt calendar, month by month

American goldfinches are unusual among finches in molting twice a year: a complete molt after nesting, when every feather is replaced, and a partial one in late winter and spring that replaces the body feathers but not the wings and tail. Timing varies with region, weather and the individual bird, so treat these months as a rough guide.

Young goldfinches from late nests are a special case. In late summer and fall they are warm brown with buffy or cinnamon wing bars, and they beg noisily from their parents at feeders, often well into September.

The spring molt is the easiest one to watch. Somewhere around March, the first yellow feathers appear on a male's throat and breast, and for the next few weeks he looks patchy, as if someone flicked yellow paint at him. The black cap comes back and the bill turns orange again. Females brighten too, more quietly, into olive-yellow. Following the same flock through March and April is one of the small pleasures of late-winter feeding.

Why goldfinches change color

Bright yellow is a breeding signal. Males show it off in spring and summer, when they sing, chase rivals and court females with looping song flights. Once nesting ends there is no display to make, and a plainer coat is less conspicuous to predators, which is the usual explanation for the switch.

The fall molt also gives goldfinches a fresh set of feathers before the cold arrives. Worn summer feathers insulate poorly; new ones keep a small bird much warmer through a winter night.

Goldfinches are not the only birds that look different in winter. European Starlings are heavily speckled with white in fall and winter, until the spots wear away in spring, and many warblers wear duller plumage in fall. The guide to why birds look different in winter covers more of them.

Where did my goldfinches go?

This is one of the most common fall questions at feeders, and there are usually three answers.

1. They changed color. The bright yellow birds you are missing may be the plain brown ones already at the feeder. Look for the dark wings with pale bars.
2. They are eating elsewhere. In late summer and early fall, goldfinches feast on natural seed from thistles, coneflowers, sunflowers, asters and other plants. Feeder visits often drop at that time, then pick up again as natural seed runs out.
3. They moved. Goldfinches wander in winter flocks, and many from the northern edge of the range shift south. Across much of the middle of the country they are present all year, but the individuals at your feeder in January may not be the ones that nested nearby. In the far South they are mostly winter visitors, and in the far North many leave for the winter.

Before blaming the birds, check the feeder. Goldfinches will skip a feeder full of stale, wet or clumped nyjer, or one with clogged ports, and come back once it is cleaned and refilled with fresh seed.

Numbers also vary from year to year and week to week. A flock that empties the nyjer feeder one day may be somewhere else the next. For more on their movements, see do goldfinches migrate.

Winter goldfinch ID checklist

If a small, plain bird at your feeder has you wondering, run through these points:

• Unstreaked body, olive-brown to buff
• Dark wings with two bold pale wing bars
• White under the tail
• Small, conical bill
• A yellowish wash on the face or throat, sometimes faint
• Travels in flocks, often at nyjer or sunflower hearts
• A bouncing, roller-coaster flight with a cheerful "po-ta-to-chip" call

If a bird ticks most of these, it is almost certainly a goldfinch. Listen, too: winter flocks keep up a soft twittering as they feed, and between feeder visits they often sit together near the top of a tree.

Winter look-alikes

Feeding goldfinches through winter

• Offer nyjer in a tube or mesh feeder, and sunflower hearts, which they take readily. Black oil sunflower works too.
• Keep nyjer fresh. It spoils when wet, and goldfinches ignore stale seed. Buy small amounts and store it dry; see what nyjer seed is for more.
• Clean feeders every week or two, since winter flocks crowd together and disease can spread.
• Leave coneflowers, sunflowers and native grasses standing in fall. Goldfinches pick the seed heads through the winter.
• Keep unfrozen water available; a heated bath draws goldfinch flocks on cold days.
