Bat Pooping Mechanics 101
Often people believe that bats must poop and pee out of their mouths because they hang upside down so much. Though some animals do expel waste from the same opening that they ingest their food (starfish, for example), bats are not one of these animals. Bats are just like all other mammals — and most other wildlife — in their pooping mechanics. They expel waste from their anuses, and they don’t do it while hanging upside down. That would be very messy.When Do They Poop?
This winged mammal usually takes care of its business while in flight. While it’s true that much of a bat’s resting time is spent suspended from a branch, rock, brick or rafter, not all of it is. Bats sometimes fly around during daylight hours within their roost or even out in the open on occasion. Bats also spend a great deal of time in the air during the nighttime hours when they’re out catching dinner. Bats spend a lot of time upside down, but they also spend a lot of time flying. Pooping in flight makes sense for them. While bats hang from their feet for a good portion of their day, they are also capable of standing on their feet. They are more vulnerable in this position because they can’t get enough lift to take flight, which is why they hang upside down. It’s easier and faster for them to get up in the air when they drop from an inverted position. Sometimes a bat perches on top of an object to relieve itself. It is more likely to do this in the safety of its roost.
