Which of the following is NOT a member of the Aves (birds) class?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Pteropus.
Pteropus, also known as the flying fox, is a genus of megabats, which belong to the order Chiroptera (bats), not the class Aves (birds). While bats can fly, they are mammals, not birds. Aves includes species with feathers, beaks, and the ability to lay eggs. Bats, like Pteropus, are mammals due to characteristics like warm-bloodedness, giving live birth, and having hair. Therefore, Pteropus is not a member of the Aves class. Examples of true birds include sparrows, eagles, and ostriches.
