Hello, I'm an expert in animal behavior and ecology. Bats are fascinating creatures that are found all over the world, and their spawning, or rather, where they give birth or raise their young, can vary greatly depending on the species.

In general, bats can be found in a variety of habitats, from caves to trees, and even in buildings. Some species of bats, like the little brown bat, often roost in caves or abandoned mines during the summer months to give birth and raise their young. Others, like the fruit bat, may roost in trees and give birth there.
Urban bats, such as the Brazilian free-tailed bat, can be found roosting under bridges or in attics of buildings.

It's important to note that the term "spawn" is more commonly associated with aquatic animals that reproduce by laying eggs, while bats are mammals that give live birth to their offspring. The process for bats involves finding a safe and suitable location to give birth and then caring for their young until they are capable of flying and foraging on their own.

edit source] Bats can spawn in the Overworld at a light level of 3 or less on opaque blocks below layer 63. Between October 20 and November 3, they only require a light level of 6 or less to spawn. On Superflat worlds, bats spawn below the top non-air layer, ignoring the usual layer-63 limitation.read more >>
