It attracts cardinals, woodpeckers, blue jays, goldfinches, purple finches, chickadees, titmice, and nuthatches. I offer black sunflower seeds in the hanging coconut feeders. Get the black sunflower seeds , sometimes called oil seeds. They are softer shelled, hence easier to crack open. Another essential bird seed is niger .
Goldfinches adore niger.
You may have dozens of goldfinches visiting your niger feeder at once, which is quite a cheering sight on a winter day. Niger is a black seed, so tiny and light you can blow away a handful with a gentle breath. Niger is also expensive, over a dollar a pound, so you won't want to waste it. Buy a hanging tube with tiny holes, designed especially for niger, and hang it where you can see it from your best viewing window. Up close to the house, even under the eaves, is fine.
