Weekend Birding: Goldfinch Plumage

American GoldfinchThe American Goldfinch is a familiar sight across much of North America. They are year-round residents in most of the Midwest and Eastern US, are friendly, don’t mind people, love backyard gardens and readily come to feeders and birdbaths.

The males are bright yellow and black in the summer with the females a more subdued color. In the winter they are both a drab, dull, grayish brown.

I’ve often wondered why some birds molt into brilliant breeding plumage and other do not. Turns out there isn’t a simple answer and it varies by species. The goldfinch, though, is an exception to its own species rule. They are the only finch that molts, or completely replaces its feathers, twice a year. Other finches, such as the House Finch and Purple Finch, only molt once a year and retain the same coloring year round.

Autumn

I have noticed that their change in plumage often matches their natural food source. In autumn, the flowers turn brown and so do the goldfinches. A few weeks ago a flock of about 50 goldfinches filled the prairie, flitting among the dying Coneflower and Goldenrod, munching on seeds.

An interesting note, goldfinches are vegetarians and only eat seeds. If they do eat an insect it’s probably by accident. A sure way to attract goldfinches to your backyard is to put up a thistle feeder.

Summer

The photo above is Yellow Coneflower growing in my backyard. There is a male goldfinch in there eating seeds. I saw him fly in but if I wasn’t watching I may not have noticed him. I’m sure there is an evolutionary reason more complex than just camouflage, but it is convenient for them that they can hide in plain sight.

    Between you and Louise I learn so much about birds on Saturday Snapshot each week 🙂

    I had no idea that some birds had completely different plumage depending on the time of the year.
    I love the story you told with this week’s photos – fascinating.

    Great photos. I love the way they are camouflaged in the photos. I have also noticed the goldfinches are one of the few birds that I sometimes see squished in the road. They must be a little slower than other birds. Here’s Mine

    I had no idea that birds molted to change colors like that. Thanks for the wonderful photos and the education.

    I’d consider it a rare delight if I got the pic of a goldfinch, which I did only twice this summer, having had to hunt for them. Thanks for sharing these beautiful photos.

    It is amazing how well they blend. I always loved the “goldfinch” and the book by Tartt is awesome as well:0

    Took me quite a while to spot the goldfinch in the cone flowers. I do love cone flowers. I think it must be my bed time.
