Northern Hawk Owl.  A rare owl of  Canada that is sometimes found in northern Minnesota in the winter.  This relatively small-medium sized owl (15-17 in.tall) prefers bogs and woodland edges for its rodent hunting habitats.  Unlike most owls, it often hunts during the day.  Its long tail gives it a somewhat hawk-like look.  I have only seen one of these, and oddly enough it was in northern Iowa.
