Minecraft wiki entry for Transportation_methods, associated text: Horses can be found in plains and savanna biomes, and can be tamed by mounting them until they produce heart particles. A saddle is required in order to control the horse, and it can be equipped with tiered horse armor (Both saddles and horse armor are found in various generated structures). Horses have variable colors and stats, with running speed, jump height, and health all being randomized for each wild horse. A horse that spawns with high stats in all categories makes a useful, tough mount for traversing rough terrain.
