The osprey is a very interesting raptor. They are sometimes called the fishing hawk, because they are almost 100% fish eaters. However the osprey is not a hawk at all, they are in their own family. They are the only diurnal raptor, one that is active during the day, that has the ability to shift a toe so that they can have 3 toes forward and one back or two facing forward and two facing behind. The only other raptors that have this ability are owls and the Osprey definitely is not an owl.
