I don't ready think it matters about the difference since I'm not a researchers in birds or anything. What I do know is that a raven wouldn't fit in my pocket like Mark does since their as big as a hawk so Mark is a crow. I met Mark years ago when I left home and like me he was starving so I decided to give him my small piece of bread as a sign of sympathy. I don't know why he decided to trust me but since then we stuck together taking whatever food we could so I didn't complain when he gave me grapes or nuts like that. We worked together since then and we only got stronger as we joined Phoenix wing and the rest is history" Angelo said going he explained it rough fit him on my he got the trust of a crow
