Hawks are some of nature's most efficient predators, possessing razor-sharp beaks and talons that are perfectly adapted for hunting prey. They are found on every continent in the world except Antarctica.
The term "hawk" has many meanings, but it generally refers to any member of the order Falconiformes, also called raptors or birds of prey. Members range in size from 4 ounces to 13 pounds. Hawks' diets range from fish, invertebrates and fruit to other birds and bats. Some hawks, such as the bald eagle, are also scavengers. Most hawks are monogamous and mate with the same partner for life.
Hawks can see about eight times more clearly than humans. Hawks have more than 1 million photoreceptors per square millimeter compared to the 200,000 photoreceptors per square millimeter found in human eyes.
