Birds in savanna grasslands are often flightless due to evolutionary adaptations that favor ground-based living. These environments provide ample food sources and nesting opportunities on the ground, reducing the need for flight. Additionally, the open terrain may favor birds that can run quickly to evade predators rather than relying on flight for escape. Flightlessness can also be a result of reduced predation pressure, allowing these birds to thrive without the need for flying.
