wings! duuhh!!
A bird has a wing as a forelimb as well as a bat, and the function of both are to help the animals fly
They both fly.
Depends On The The Bat And The Bird
It Provides warmth..and allows the bird to fly
A bat is a type of mammal. It is not a bird.
The external structure is the wing. Its bones are so not heavy that the wind takes the bird up and allows it to fly.
If these are true wings, this is a bird. BTW not all can fly: penguins
the wings both flap they could be the same color they both make the animal fly.
Bat is the mammal that can only fly.
well if a bird look like a bat then it's a birdbat
Its because fly is both a noun and a verb, so it can be done, and in this case a bird happens to be able to fly. But sadly, bird is a noun and not a verb, so you cannot bird.
No it is not but as bold as a bat is
