Bats because they have wings they flap to get going unlike gliding squirrels!
The bat is the only mammal that has 'true' flight. All other 'flying' mammals are gliders.
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".
Bats are the only mammals capable of true flight, they are all nocturnal, and they emit high-pitched sounds.

The only reptiles capable of true flight were pterosaurs.
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.
The only animals capable of true flight are birds, bats, and insects.
There is one group of mammals that fly. They are called bats. A number of other mammals can glide, but this is not true flight. Many insects, which are not related to mammals or birds, can also fly.
Bats are the only mammals that have true flight (distinct from the extended glides of animals like the flying squirrel), and the only land mammals that use echolocation.
