Question

Whether bat is a bird or an animal?

Answer 1

Hint: One thing to clearly clarify at first is that bat is surely an animal. Obviously, it shows a wide range of characters to signify that it is an animal and not a plant.
Bats are animals that fall under the category of vertebrates. The vertebrates have 5 main classes:
1. Fishes
2. Amphibians
3. Reptiles
4. Birds
5. Mammals
Now we would be placing bats in the relevant category by learning its characters.

Complete answers:
Bat is a mammal that is able to fly and is a nocturnal creature. The main characters that bats show so as to fit them in the class of mammals are:
1. They give birds directly to the young rather than laying eggs.
2. They take care of the young ones very closely. They have mammary glands and feed the young ones their own milk.
3. They have their bodies covered with hairy fur, unlike birds who have their bodies covered with feathers.
4. These are the basic characteristics which separates bats from the classes of birds and places them under mammals.

So bats are mammals and not birds.

Note:
The point to be noted here is that bats are the only mammals that can fly. They are nocturnal which means that they sleep during the day and are most active during the night. They hang upside down the ceiling of old apartments and caves. They feed on insects, pests, blood of other mammals, fruits, etc. depending on the species. There are as many as 14000 species of bats found worldwide. The bats that feed on the blood of humans are often known as ‘vampires’.
