Billie · Answer 1

Have similar niches.

Explanation:

The species that share the similar niche and other resources cannot co exist together and one species may completely exclude the other species. This is known as competitive exclusion principle.

Two species of cuckoo birds lives on different island. 14 islands have one species, 6 islands have the other species, 13 islands have neither, and none has both this is because they share the similar niches and later get separated into the different island due to the competition.

Thus, the correct answer is option (b).
