Hawks are a group of medium sized birds of prey. The more common ones here in Florida are Red Tailed, Red Shouldered and Coopers Hawk. There's also a subspecies called the Northern Harrier. Female Harriers outnumber the males 20-1. The male is known as the "Grey Ghost" as he's grayish in color compared to the brown females and is a more rare sighting. They all have excellent vision with 5 times more photoreceptors than humans. They even have the ability to see ultraviolet light and can detect polarized light and magnetic fields. The center area of their vision is magnified to make them lethal to their prey from far away.
