Wildebeest crossing a river; large herd.

A large herd of wildebeest and zebras are migrating across a river. The wildebeest are wading through the shallows of the river, while some are already in the water. The dry, grassy plains are dotted with the animals, and a lone acacia tree stands out in the distance. The migration is a seasonal event, driven by the need for fresh grazing land. The animals are traveling in large groups for safety and to find food.
