A curious deer was spotted peering through the windows of a biology lab at the University of Alberta.

Footage from February 11 shows the mammal gaze through the lab's windows while eating some grass.

The filmer wrote on their Reddit post: "A deer kept looking people during my bio lab, like a reverse zoo.

"They were very distracting. They actually came up at the other side of the building at the opposite windows, then quickly wandered around to this side lol. We thought they left and then they came out of nowhere again."

Deer at university eats grass beside window because there is less snow there, and watches biology students who are inside while munching on grass. Alberta, Canada.
