They differ due to adaptations that the birds have made to their environment. For example, some birds have adapted to a fish eating diet and so generally their beaks become long and thin, useful for catching lots of small fish at once. Whereas other birds may live on a diet of seeds and nuts, requiring a stronger beak, which is capable of cracking open the shells of nuts and seeds.
Differences in a bird's beak size and shape produce differences in fitness that cause natural selection to occur.

Birds can differ from each other in many ways. Different species differ in both size and appearance along with instincts and ways. Birds of the same species can differ from each other just the same way as humans. E.g each person is different in their own way due to attitude, colour and thought. It's exactly the same. Many birds have hooked beaks, many have beaks for siphoning water and others have beaks for catching insects. Their diet varies beyond group species as do their appearance. Many birds may look the same but they each differ in thought, language, colour, size and diet.
Birds of paradise use their beaks to eat fruit.
Birds need their beaks to obtain prey and defend themselves.
