The beak, bill, and/or rostrum is an external anatomical structure found mostly in birds, but also in non-avian dinosaurs and some mammals. A beak is used for eating and for preening, manipulating objects, killing prey, fighting, probing for food, courtship and feeding young.

Birds can be of three types based on their foot size as small size leg, middle size leg and large size leg
Explanation:
- the type of natural selection that has occurred in the given population is stabilizing selection.
- There are two types of birds with large feet and small feet. Each type of bird has specific advantage in gaining their nutrition and escaping from the Predator.
- However if there is medium size bird they will die because they do not get advantage in any of the above factor and hence they become less feet and eventually will die due to predation on lack of food. This type of natural selection is known as stabilizing selection.
