Burros are small domesticated donkeys, known for their strength and endurance. They are often used as pack animals in rugged terrains, making them valuable for transportation in areas where vehicles cannot easily go. Burros typically have a calm temperament and can be found in various colors, including gray, brown, and black. Originally brought to the Americas by Spanish explorers, burros have adapted well to different environments. They are often associated with wild burros, which are descendants of domesticated animals that have returned to the wild. Burros play an important role in agriculture and tourism, especially in regions like the Grand Canyon.
