Answer:

Prezygotic barriers:

1. Habitat isolation

2. Behavioral isolation

Explanation:

Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.

The two mechanisms of the pre-zygotic barriers are the:

1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.

2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.

Thus, Habitat isolation and Behavioral isolation are correct.
