In spring, they begin to acquire their summer plumage. In fall, the birds molt again into the duller winter garb.
The plumage of a goldfinch changes color due to the molt process, where they shed old feathers and grow new ones. During breeding season, male goldfinches often develop brighter and more vibrant plumage to attract mates. The diet of a goldfinch can also affect the intensity of its yellow coloring.
If you mean American goldfinch, they go through a molt in early fall and resemble females, then regain the bright colors in Spring.
