The CIncinnati Zoo welcomed a Eurasian Eagle owl chick four weeks ago. Named Caspian, the young Owl could grow to have a wingspan on six feet from tip to tip! Wild Eurasian Eagle Owls are found across Europe, Asia and even in parts of Northern Africa. Their diet consists largely of small mammals, but full grown Eagle owls can prey on larger animals like foxes, and young deer. The Eurasian Eagle Owl (Bubo bubo) is one of the largest owl species in the world.
