Feral Burros

Location: United States

Population: Fewer than 9,000

Wild burros are offspring of domesticated donkeys introduced to North America by early explorers and settlers. As time passed, some of these donkeys either fled or were set free into the wilderness, eventually acclimating to their newfound surroundings. Today, feral burros roam across different areas, notably in the southwestern United States, where they’ve formed communities in dry and semi-arid landscapes. These resilient and adaptable creatures have integrated themselves as a distinctive component of the local ecosystems.
