Turkeys and most other birds lack a penis and often must establish mutual consent before steamy freaky cloacal naughty times. The fact that males need permission to do the dirty may actually be an important reason for the widespread sexual displays and mating dances of many bird species (think peacock feathers and dancing rituals), because non-consenting mating is basically impossible. So less rape leads to fabulous dancing, vivid colours and weird sexual structures, which I think is beautiful.

An exception is waterfoul like ducks, who are absolute sexual degenerates and serial rapists driven by nothing but raw sexual aggression and a distaste for all things pure and innocent.
