Of the roughly 1.1 billion sheep on Earth, roughly 1.1 billion have no idea who Barack Obama is. But there are at least eight sheep who can recognize the former president by his face. After a few days of training at the University of Cambridge in England, the animals learned to select the former president's portrait out of a collection of photos.
Recognizing Obama meant the sheep won a snack. The scientists, in turn, were rewarded with better ways to measure sheep brain function.
The woolly critters learned to recognize human celebrities through three training scenarios. In each step, the sheep were presented with two options: a photo of the celebrity facing forward for the camera, or a photo of something else. The farm animals had 15 seconds to approach the celebrity image and trigger an infrared sensor. If the sheep chose correctly, the testing device popped out a treat. The first test was the simplest. The sheep chose between a black screen or the celebrity face. The second round was slightly more challenging. Celebrity profile photos were randomly paired with images of one of 62 objects, all head-sized but lacking faces. (A sheep might have had to select Emma Watson vs. a football helmet or gas lamp, for instance.) The third test pitted the sheep's celebrity targets against unfamiliar humans.

Funny but not surprising in the least. Just your basic classical conditioning, AKA Pavlovian conditioning.

Doesn't surprise me at all. My Koi all come to the surface and expect to be fed when I am near the pond. Anyone else - they go deep. If fish can recognize me, then it certainly makes sense that sheep could.

I always assumed only sheep call other people sheep..
Interesting study though, despite the lowbrow attempt at humour.

Please tell me you didn't dump the entire food box in the water!
