The feet of birds are adapted to the lives which they lead. Birds which spend their time in the water have
webbed feet ; those which spend their time in the trees have feet for perching; climbing birds like the parrot
and woodpecker have two toes in front and two behind and can thus climb with ea se; those living in marshy
districts, such as the stork and heron, have long stilt-like, legs ; those which spend most of their time on the
ground have feet suitable for walking.
