The Purple Finch is the bird that Roger Tory Peterson famously described as a “sparrow dipped in raspberry juice.” For many of us, they’re irregular winter visitors to our feeders, although these chunky, big-beaked finches do breed in northern North America and the West Coast. Separating them from House Finches requires a careful look, but the reward is a delicately colored, cleaner version of that red finch. Look for them in forests, too, where you’re likely to hear their warbling song from the highest parts of the trees.
