Statement 1: It is conserved under the agreement on the African-Eurasian Migratory Waterbirds (AEWA).
The African-Eurasian Migratory Waterbird Agreement (AEWA) is an international treaty that aims to conserve migratory waterbirds and their habitats in Africa, Europe, the Middle East, and parts of Central Asia. It was adopted in 1995 and came into force in 1999. The agreement includes a list of waterbird species that are considered to be of conservation concern, and the crab-plover (Dromas ardeola) is one of the species listed under the agreement. Therefore, statement 1 is correct.
Statement 2: It is found mainly in coastal regions of the Indian Ocean.
The crab-plover is a bird species that is primarily found in coastal regions. It is distributed along the coastlines of the Indian Ocean, from eastern Africa to the Indian subcontinent and Southeast Asia. It inhabits sandy and rocky shores, sandbars, and estuaries. Therefore, statement 2 is correct.
Conclusion:
Both statement 1 and statement 2 are correct. The crab-plover is indeed conserved under the AEWA, and it is found mainly in coastal regions of the Indian Ocean. Therefore, the correct answer is option C - "Both 1 and 2".
