Yes, that would be a real, severed female turkey head. On a stick.
In 1965, Pennsylvania State University researchers Martin Schein and Edgar Hale started the experiment reasonably enough by presenting male turkeys with a model of a female turkey. The living turkeys got their sex on, because they're just turkeys, and at the sight of a turkey-shaped object they were like "Close enough for my feathered boner!" The researchers then severed the feet, tail and wings from the model, and the oblivious turkeys kept on doing their thing.
Is anyone else imagining a deep Barry White voice making turkey sounds? "Blblblblblblblb!"
The researchers kept removing sections of the turkey until all they were left with was the head of the model. That didn't discourage the males one bit -- just the fake head was enough. That was all probably good data, and helpful to farmers and such who are looking for the best way to breed turkeys. And then the scientists were like "Well, we've come this far. Let's go put a real turkey head on a stick and see if we can get a male turkey to f**k it."
They did, and then they watched as the males frantically humped the severed heads of their lovers. All while at least one scientist in the room tried desperately to hide his erection.
"Fifty bucks says he fucks this, too."
