Why might birds that swim a lot have webbed feet?
The primary use for webbed feet is paddling through water. Here’s how it works: as the bird pulls its foot backwards through the water, the toes spread apart, causing the webs to spread out. Webbed feet are useful on land as well as on water because they allow birds to walk more easily on mud.
