![]() Not all ducks have orange feet and they can also be blue and gray. The change in color is caused by hormones. Once breeding is over their feet return to a paler orange. This is thought to help them attract a mate. Mallards’ feet are orange and when breeding season starts their feet go a bright orange color. The toes are then folded together on the forward stroke to minimize water resistance. Ducks push their feet both backwards and downwards on each strokeĭucks use their feet to swim and they push both backward and downwards with their feet which the webbing stretched out to provide maximum forward motion. They will also use their feet for steering when swimming to quickly change direction.ĭiving ducks also have extra lobs of skin on their back toe to provide more webbing and better underwater swimming efficiency. Ducks use their feet to help them swim underwater and for steeringĭucks will paddle their feet when feeding underwater to counteract the buoyancy and so stop them floating to the surface. Their arteries and veins are intertwined and before the blood pumps into the ducks’ feet the heat is transferred to the blood coming back into the body from the vein in the feet. Researchers have found that ducks do not lose much heat from their feet.ĭucks do not lose much heat from their feet and they are able to stand on cold surfaces by using countercurrent exchange. Ducks’ feet don’t freezeĭucks use their feet to regulate their temperature. ![]() This section sits above what we would consider their toes. Some of the lower bones of the foot are fused to form an extra segment of the leg called the tarsometatarsus. Most birds are digitigrade, which means they walk on their toes rather than their whole foot like humans. There are over 400 species of birds that have webbed feet.Īudubon explain that these webbed feet evolved independently as they are such a good way to swim through the water. Many animals found the advantage of webbing including birds. Webbed feet evolved independently in many types of birds This is also used to help with swimming and can expand and contract when the duck swims. Some diving ducks also have a lobed hind toe, which means a lobe of skin sticks out on either side of the toe. This means that the front three toes are joined by skin between them, creating two webs. The webbed toes of ducks are in fact called palmate. This occurs normally in many animals such as ducks and has evolved in ducks to help with swimming. ![]() Syndactyly is the name given when two or more fingers or toes are fused together. This is similar to many birds and this arrangement of toes is called Anisodactyl.ĭucks also have claws on the end of each toe. Three toes point forward and one much smaller toe points backward in ducks. They have specially adapted waterproof feathers and amazing webbed feet which enable them to swim through the water with speed and grace.įind out more about these amazing ducks’ feet.
