This deer must’ve forgotten it’s supposed to be a vegetarian during this encounter with a bird. Either that or it was just branching out and trying some new food groups.
According to Linda Loo, she noticed birds flying around the buck and running into its head. She was trying to figure out why they were attacking the deer through her window, then she saw the bird on the ground. Apparently, the birds had been trying to distract the deer to protect the other bird.
