What makes birds sucessful in the wild?in the wild
In addition to the above answer, consider the simple concept of flight, and how that enables birds to much more easily and successfully obtain the food they need to thrive and reproduce. It also allows them to migrate so that they can adapt to changing weather patterns/seasons and survive in a wider variety of locations, again making food more consistently available to them.
Depending on the bird species, many are scavengers, and can survive on a wide variety of food types, again increasing their long term viability as species. The ability of flight also allows them to live in locations less vulnerable to predators, such as high in trees or cliffs.
Birds have many characteristics that make them successful in the wild. One characteristic that makes birds successful is that they have hollow bones. The reason that they have hollow bones is to make them more lightweight for flying. In addition, birds have air sacs within their bodies that are connected to their lungs. These air sacs make it possible for them to obtain more oxygen. They need this extra oxygen because it takes a lot of energy to fly. Birds also have very good eyesight. For example, they need exceptional eyesight in order to land successfully.
