牛背鹭等待白犀牛移动，共生关系，非洲

nating wildlife clip of several cattle egrets standing alert, waiting for a large white rhino to move through the tall grass. The birds strategically follow the rhino to catch insects stirred up by its heavy footsteps. This footage perfectly illustrates the commensal relationship between African megafauna and birds. Captured in the natural savanna habitat, this shot is ideal for nature documentaries, ecological studies, and educational content on animal intelligence and survival strategies
