A bird's beak is evolved for the sort of food the bird eats. For example, birds who eat hard seeds have strong beaks to crack them open. Birds who drink flower nectar have long skinny beaks to fit inside the flowers.
Depends on the bird really. Hummingbird beaks have gotten longer & Skinnier to fit in flowers, while other birds got shorter and fatter so the blunt beaks can crack shells.
yeah its a bird so it does have a beak.
