Which of the following is an endemic species?

Nicobar pigeon

The correct answer is Option (1)- Nicobar pigeon

The Nicobar pigeon is an endemic species.

Explanation:

• Endemic species are those that are found exclusively in a particular geographic region and are not naturally found anywhere else in the world.
• The Nicobar pigeon (Caloenas nicobarica) is native to the Nicobar Islands in the eastern Indian Ocean.
• It is characterized by its iridescent plumage and is known for its striking appearance and unique habitat.

Unlike species such as the Indian wild ass, desert fox, and Indian rhino, which may have broader distributions beyond specific regions, the Nicobar pigeon is restricted to the Nicobar Islands, making it an endemic species to that area
