Learn why geese's feathers stay dry when they swim, explained in a simple way for young children.
Hi there! Did you know that geese are great swimmers? When they swim in the water, their feathers don’t get all wet like our clothes do. This is because geese have a special trick!
Geese have a tiny gland near their tail called the preening gland, which makes oil. After swimming, the goose uses its beak to spread this oil all over its feathers. This oil acts like a waterproof jacket and keeps the feathers dry.
Because of this oily coating, water slides right off their feathers, so they can stay warm and dry even while swimming. Isn’t that amazing?
