Owls are a type of bird that is bird of much interest and has been for some time. They are often associated with wisdom which dates back to ancient Greece where the Goddess of Wisdom, Athena, was often depicted or symbolized as an owl. Owls are often considered to be a bad omen as well, which may be a result of their solitary nocturnal nature. Their most disctint feature is their head and face shape. They have a flat face with forward facing eyes combined with a hawk-like beak. They also usually have some sort of prominent disc of feathers surrounding each eye. Most owls can turn their heads to a significant degree, as much as °180, giving them a full view of their surroundings without the need to turn their body. There are two living Families of owl: Tytonidae – or Barn-owls, and Strigidae also called “Typical” or “True” owls.
