Ostrich Behavior and Adaptations

Ostriches are unique, flightless birds with remarkable adaptations. They belong to the ratite group, which evolved flightlessness independently. Ostriches are the fastest two-legged runners, thanks to their specialized legs and feet. Their large eyes provide excellent vision, and their size helps with energy storage.
