* Scavengers: They are all primarily scavengers, meaning they feed on dead animals. This is an important role in the ecosystem, as it helps to remove carcasses and prevent the spread of disease.
* Opportunistic eaters: While they primarily scavenge, they can also be opportunistic predators and will eat a variety of food sources, including small animals, insects, and even plants.
* Social animals: While their social structures differ, all three are social animals, living in groups or flocks. They cooperate in various ways, such as raising young, defending territory, and finding food.
* Highly intelligent: All three species are known for their intelligence. Crows are famous for their problem-solving skills, buzzards have excellent vision and can navigate long distances, and hyenas are known for their complex social structures and communication methods.
