They can see in daylight just like other mammals. Bats choose all kinds of dark nooks and crannies for their homes called roosts. They can crawl on all fours, sleep upside down for hours at a time and even give themselves a good cleaning while dangling by one foot. When it is not in flight, a bat's normal position is head down. A bats hold on its roost is so powerful that it may not be broken even when the animal dies.
Bats do drink water.
Bats are pollinators, seed dispensers and pest controllers. Most bats are clean, healthy and not aggressive toward humans. Bats are shy and avoid people. Even sick bats rarely attack, unless they are threatened. Bats do get rabies, as do most mammals.
