The pigments in their feathers are carotenoids that are directly linked to immune system functions. Goldfinches, like most small songbirds, molt twice each year. Could that be right? We have goldfinch at our feeder daily. A few weeks back I noticed a lot of yellow feathers blown into a corner on our patio.
I pointed them out to my husband and it remained a mystery to us until I read the color change David explained. David, I live in Georgia and enjoy goldfinches greatly. One observation I have made is a very small yellow spot at the base of the tail in late winter. These birds look like goldfinches, yet I am unsure. I would love to supply a photograph, but alas, I have been unsuccessful.
Please advise if possible. I have heard that the hormonal response is triggered by the goldfinch eating certain berries. Is there anything to that? David, I live in Toronto. We have been feeding goldfinches all winter on Niger seed. Today I have seen a gold?
The black cap looked almost fake, but not quite a crest, and the eyes seemed to protrude… almost as if he were wearing a mask.
He looked like he needed some preening, a bit tousled. Sat Apr David, I noticed a big change at my feeders over the weekend all of a sudden there is less activity. My orioles I assume have left for warn climes. May I assume the absence of my goldfinches is they are molting? I sure am missing seeing all the birds every morning!
Thanks for a useful site. Just wondering if this hormonal change that causes drab vs. We are watching the goldfinches at our 2 feeders scrappy little birds! And yes, the males are just beginning to brighten up. Pingback: Waiting for Joaquin… Kite Dreams. Pingback: Visit Joplin Missouri Blog. Her theory is that it was a juvenile born late in the season and missed molting. I have what i think is a female goldfinch,but might be a male.
This is called an eclipse plumage, and it may last anywhere from just a few weeks to many months. In male Mallards, eclipse-ing means the iconic green head softens to a dingy gray or brown between June and September. During the molt they keep an intermediate plumage, with a few green feathers still visible, though scruffy-looking.
By October the males should be back in their classic plumage. The timing on the return to breeding plumage varies, so between June and November keep a close eye on any groups that look to be all female.

Some species such as the Cardinal or the Chickadee merely use the annual moult to refresh their plumage; the feather colours remain the same all year-round. Others, however, use the moult as an opportunity for change. Vibrant breeding colours are swapped for camouflage, either adapted to the winter conditions for those that stay, or for the long journey and winter habitats of migratory species.
And that means going through a second moult in the spring, to regain the breeding colours. American Goldfinches are an example.
Most warblers will do the same; the bright blues, oranges, yellows, stripes and patterns of the summer are exchanged for drab greens, olives and yellows that make most species appear very similar to one another. Many birds will have this pattern of being colourful in the summer and camouflaged in the winter.
