While many ducks have webbed feet that are used to propel them through the water, geese and ducks usually have stiff toes that prevent them from slipping through the slits of the shallows. The lack of webbed feet helps to conserve energy. Diving birds rely on their sharp senses to locate food, which is why they are usually found in thick cover. They also usually have bright feathers that allow them to reflect sunlight. These characteristics help the birds stay warm even in cold waters.
