Can you tell a House Finch from a Purple Finch or Cassin’s Finch? These finches are some of our favorite common feeder visitors, but they can make for very tricky IDs! Adult males of all three species sport red plumage in varying shades and intensity, while females and immature males are similarly brown and streaky. But even though these birds look very similar, there are a few visual keys to ID. Check out our quick review below, or explore all the details with a full explanation from Project FeederWatch.
