Photos of bald eagles have virtually no commercial value because the birds are so common. But everytime I see one, I can't help but stop and at least try to get a picture. This one is up the North Fork of the Flathead River, taken on Sunday. Glacier has about 13 nesting pairs of bald eagles. When shooting birds, it is imperative that there's a blue sky background. Gray skies with white heads don't cut it — the head of the bird will almost disappear.
