Like other mobs that burn in sunlight, burning occurs at dawn when the sun is 15degrees or greater above the ground, unless the skeleton is within shade or water. They will attempt to find shade or water to keep from burning.
Skeletons are the most readily available source of bones, and thereby bone meal, a useful resource. They can also drop arrows. Each skeleton will drop 0-2 bones and/or 0-2 arrows upon death. Although skeletons' fired arrows can often be seen stuck in blocks, those cannot be picked up by players. Because of its valuable drops, dungeonscontaining skeleton spawners are sought for mob grinding purposes.
Skeletons also have a 1/40 chance of dropping a bow, only when they are killed by the player. There is a 1/5 chance that a dropped bow isenchanted with Power I, with rarer chances of Power III, Flame I, or Infinity I. Although extremely rare, it is also possible for a bow to drop with all three of these enchantments.
Killing a skeleton from 50 meters away is necessary for the achievement "Sniper Duel". (See below.)
