Turkey love

When it comes to affinities for particular female body parts, turkeys are face men.

In the 1960s, turkey biologists at Pennsylvania State University found that, when placed in a room with a lifelike model of a female turkey, males mated with it as eagerly as they would a living one. Intrigued by this, the researchers then removed parts of the model, one piece at a time, to determine the minimum stimulus it would take to excite the birds before they would lose interest. Missing tails, wings, feet — the amorous males couldn't care less. Even the absence of the body itself, they didn't mind: When all that remained of the model female was a head on a stick, the males still tried to mate with it.

The researchers speculated that male turkeys' head fixation relates to their mating style. When they mount a female, they cover her completely, except for her head. Because it's all they can see, the head thus becomes the focus of their erotic desires.
