Imagine taking a dust bath to keep clean! Sparrows have to bathe in dust to keep pests out of their feathers. Tiny bugs such as fleas and lice can be a problem for birds. In order to keep pests away, birds preen themselves. Preening is just a fancy name for keeping clean. Birds preen by running their beaks through their fathers. The beak acts like a tiny comb, picking up dirt, bits of leaves and pesty bugs.
A bird called the starling has the most remarkable way of keeping its feathers tidy. It uses ants! A starling covers its wings with ants. The ants gobble up insect pests that hide among the starling’s feathers.
Most birds like to dip into a lake or a puddle of water to wash off. They splash around like toddlers in a pool, hopping first on the leg, then on the other. Birds like to have fun while washing up too!
