When does the herd of buffalo choose a knew leader?

A herd of buffalo typically chooses a new leader when the current leader is no longer able to guide the group, either due to age, injury, or death. The herd often looks to a dominant or experienced female, as they usually lead the group in search of food and water. The transition can occur gradually as the new leader emerges, demonstrating strength and protective instincts. This leadership shift ensures the herd's stability and survival in their environment.
