Osprey are a type of Hawk, which can kill small rodents, other birds and possibly small pets like cats. Although Osprey usually stay away from humans as most feral birds do if provoked they can fight back. They have claws and a sharp beak so it is recommended to leave them alone due to this. You should stay away from all wildlife regardless of how friendly they appear to be because they could carry dieses that make that act differently.
