How far do bats travel to feed?

The Goblins are a neutral race in the World of Warcraft and tend to do everything for profit. However prior to that, during the great wars they sided with the Horde and still currently favour the Horde. They are green-skinned and the same height as Gnomes. Most goblins are engineering geniuses, but appear to have an insane side to their personality. Goblins are not always neutral; many are employed by the Black dragonflight and were responsible for welding plates onto the scales of Deathwing. More recently, they assisted Nefarian in his creation of the Chromatic dragonflight.
