Passage Four
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!
After reading this passage, we can see that () A. all birds live water B. birds get very dirty C. staying clean is very important to birds D. preening takes a lot of time
