This article spoke about a particular bird, the jackdaw, who has very similar eyes to the human. Dark pupils and very silvery irises. It is thought that the bird uses their eyes to communicate in the same manner as humans. We already knew that we as humans shared the ability to communicate with our eyes, but it was not known whether or not any other species can do the same thing. It is now known that this particular bird, the jackdaw, can do just that. The question remains if they can utilize what they understand about their eyes to interpret what we, humans, are thinking or communicating.
