Have you tried Playbird magazine? (Rim shot.)
But, all seriousness aside, I've seen nature books that contain such photographs openly displayed on the shelves of morally upstanding bookstores. And nature shows on TV feature mating birds and animals quite regularly.
I've never seen a calendar or poster that showed birds doing the wild thing, though.
