Red deer = are not always strictly vegetarian.
Originally uploaded to YouTube on May 16, 2010, but is now viral again, it is a short video captured by Linda Ford of the United States. He films in his own garden the macabre scene of a deer blithely picking up a young bird from the ground with its teeth, chewing the helpless creature in its jaws, and then swallowing it, while the two birds sway helplessly but helplessly in the face of the deer devourer.

A deer that devours birds? Amazing, impossible. but perfectly true, but apparently it is not the only case.
