Sheep can remember faces: study
Sheep have demonstrated a celebrity-spotter's ability to recognise faces of famous people, including former US President Barack Obama.
Scientists showed how they could be taught to recognise screen-shot images of celebrity faces using food rewards.
The team trained eight sheep to recognise the faces of four celebrities - TV journalist Fiona Bruce, US actor Jake Gyllenhaal, Harry Potter star Emma Watson and Barack Obama - from photos on computer screens.
Lead scientist Professor Jenny Morton, from Cambridge University, said: "Anyone who has spent time working with sheep will know that they are intelligent, individual animals."
