Birds have evolved different methods of locomotion based on their body structure and the environment in which they live. Birds that frequently inhabit trees or bushes tend to hop or jump to move between branches, while birds that live on the ground or in open spaces often walk or run. Each method of movement is adapted to help the bird navigate its specific habitat and find food efficiently.
Animals which walk on just 2 legs are called bipeds, they are bipedal.
i guess that they are just light
Birds that cannot fly often rely on alternative methods for keeping themselves safe from danger. Some common strategies include camouflage, living in inaccessible habitats, forming large groups for protection, such as in the case of penguins, or using mimicry to imitate other harmful species and deter predators.
