Stimuli Eliciting Sexual Behavior in Turkeys
Male turkeys aren't fussy. Give them a lifelike model of a female turkey and they'll happily try to mate with it as eagerly as they would with the real thing.
This observation intrigued Martin Schein and Edgar Hale of the University of Pennsylvania, and made them curious about what might be the minimal stimulus required to excite a turkey. They embarked on a series of experiments to find out. This involved removing parts from the turkey model one by one, until the male turkey eventually lost interest.
Tail, feet, and wings were all removed, but still the clueless bird waddled up to the model, let out an amorous gobble, and tried to do his thing. Finally, the researchers were left with a head on a stick. And surprisingly, the male turkey still showed great interest. In fact, it preferred a head on a stick over a headless body.
Schein and Hale subsequently investigated how minimal they could make the head itself before it failed to elicit a response. They discovered that freshly severed female heads impaled on sticks worked best, but if the male turkey had nothing else it would settle for a plain balsa wood head. Turkeys evidently adhere to the philosophy that if you can't be with the one you love, then love the one you're with.
Curious about the mating habits of other poultry, Schein and Hale performed similar tests on White Leghorn Cocks. They published their results in an article with the intriguing title, "Effects of morphological variations of chicken models on sexual responses of cocks."
