Wildebeest migration crossing river.

A large herd of wildebeest is crossing a river. Many wildebeest are in the river, wading and drinking, while others are on the banks and in the grasslands leading up to the river. The scene suggests a significant migration, likely part of the annual wildebeest migration in the Serengeti or similar African savanna ecosystem. The dry, grassy plains and the riverbed indicate a dry season or a time when water sources are scarce.
