Bird having a drink

Like all animals, birds need water to survive. Though they can extract some moisture from their food, most birds drink water every day. Birds also use water for bathing, to clean their feathers and remove parasites. After splashing around in a bath for a few minutes, a bird usually perches in a sunny spot and fluffs its feathers out to dry. Then it carefully preens each feather, adding a protective coating of oil secreted by a gland at the base of its tail.
