Interesting theory......I would say that birds have wings mainly as an aid to almost evrything they do. Carnivorous birds need their wings to swoop down on smaller birds. All birds( that have wings and are capable of flying) use their wings to evade predators and humans. They use them to hunt, to migrate, to collect materials for their nests....many things would not be available to brids if they did not have wings, and most of those things neccesary, hence the answer. They just need them.
Their beaks developed to cater for their different diets. A vulture, for example, needs a beak that is capable of tearing flesh off dead animals. In contrast, a hummingbird needs a long, slender beak to enable it to probe into flowers to sip nectar.
yes they do. the reekatine pilgrims had feathers scales and horns.the feathers sprouted just above the rear end and the scales most of their feet. the horns only grew on the children and came off around their 4th year of life. as near as we can figure about them and were they went is they used to live in southern chad. they seem too have migrated too shikland.
To eat, drink and carry food to their young
they have beaks because they need the beaks to get their food.
So they can eat different foods.
Because they're birds.
Not all animals have beaks or bills. Think of dogs, cats and cattle. Definitely animals, and definitely not a beak in sight.
The beak of a pigeon is smaller than the beak of a hawk.

Birds
The Oystercatcher (family Haematopodidae, with a single genus, Haematopus) is a bird with a slender beak.
In Aesop's tale of The Fox and The Crow the fox saw that the crow had a piece of cheese in its beak.
That's what they are called.....
All birds have that, it is to give their beak some flexibility. It's not a hole, it is covered with skin. If the beak was solid, when they opened their mouth it would cut into their throat. With the gap there, the sides of the beak can move past the head and let them open their beak.
Galapagos finches showcase natural selection principles: variation in beak size reflects genetic diversity among individuals; those with beaks suited to the available food sources survive (survival of the fittest); over time, the population's average beak size may change as those with advantageous traits pass them on to offspring (reproductive success).
If it has a beak they tap until the egg cracks and they toddle out.
there big yellow beak
animals use their fangs,beak,sharp teeth and claws
