We have some 'ground birds' as that's what we call them, for you rarely see them on the bird feeders. There's usually 6-15 of them at any given time on the ground. Once in a while you may see 'one' up on a tree limb, but they're usually in the same area together on the ground. They are small fluffy looking birds very similar to the size of the Carolina Chickadee, having a fairly short tail. Will up the pics if I figure out how...
