I hung up a thistle seed sock to see if I could lure in goldfinches and saw a little male like this in his drab winter plumage. -American goldfinch male in winter plumage. He loses the black patch on his head as he fades to a dun colour.
American Goldfinch Habitat: Open areas like yards, fields, fencerows and groves. Diet: Seeds and berries. Backyard Favorites: Supply nyjer (thistle) in a tube feeder with multiple ports, or in a nylon stocking. They also will come to a sunflower feeder.
