Bats are the only mammals capable of true flight. Their wings are like hands with skin stretched between modified finger bones.Bats and most birds a capable of sustained flight, and they are vertebrates
Bats are unusual mammals because they are the only mammals capable of free flight. Creatures such as the various species of possum known as gliders are not capable of free flight - they can only glide between high points. Bats are therefore the only true "flying mammals".
There is only ONE thing that is noctournal AND is a mammal, and that is a bat. Currently, this is the only known MAMMAL in the world that is capable of flight for however long it wishes. There are sugar gliders, but they can only GLIDE. Of course, there are owls, but they are birds.
The only mammal capable of true, natural flight, is the bat. 'Flying' Squirrels are gliders rather than being capable of true flight. It's more accurate to say they prolong the process of falling. Lastly, the other main mammal species that flies, is we humans, in our aircraft.
