Legs & Feet

Pine Siskin Feet Perching birds have three forward toes and one pointing backward for grasping.
Spotted Towhee Feet Ground feeders like sparrows and juncos scratch the ground for food. They also have three forward toes and one hind toe.
Cooper's Hawk Feet Birds of prey like eagles, hawks and owls have strong legs and feet with sharp, hooked claws to grasp and carry prey.
Hairy Woodpecker Feet Woodpeckers have two toes forward and two toes backward with sharp, down-curved claws.

Factoid: Putting pressure on the inside of the foot causes the toes to lock around a perch. This is how birds can sleep without falling off branches.
