Do yellow finches go south for the winter?
There is a resident subspecies in California that does not migrate. Most of these goldfinches migrate southward out of Canada in winter. They move to the United States, as far south as Florida, the Gulf Coast and the border with Mexico.
Should I feed finches in the winter?
Keep feeders full when winter is toughest.
Birdfeeders are most attractive to birds in winter, when natural food supplies are least available. Seed eaters such as finches, sparrows, titmice and chickadees may flock to feeders--in higher numbers than natural food sources alone in the immediate area could support.
Do yellow finches lose their color in winter?
American Goldfinch follows this pattern. Beginning in September, and continuing for six to eight weeks, they molt all of their feathers, ending up with a completely new and pristine set of feathers (and drab colors) as they head into the winter. And in September another complete molt begins.
Birds are well equipped to survive the coldest of temperatures. They store fat during the short days of winter to keep themselves warm during the long nights. During those freezing nights, they fluff their feathers to trap heat and slow their metabolism to conserve energy.
