Would you be able to grasp a tree branch with your toes and then fall asleep, without falling? No, because your feet are not made for living in trees.
Birds have feet that suit their way of life. Birds that perch on branches have toes that curl around the branch to give a tight grip. The grip is so tight that the bird doesn’t fall off even when it sleeps.
Birds that find their food in the ground have short, blunt toes like tiny rakes. They scratch the ground to turn up insects and seeds. Ducks, geese, and swans have feet like paddles to help them swim in water. Birds of prey, which eat small animals, have sharp, curved claws – just right for grabbing the creatures they hunt.
Climbing birds, like parrots and woodpeckers, have two toes pointing forwards and two toes pointing backwards. Cassowaries and most other fast-running birds have three toes on each foot.
