The factors most often associated with speciation in these areas are dispersal and colonization.
Dispersal and colonization.
- Dispersal of the bird populations can happen for a variety of reasons and is essential to speciation.
- Through dispersal, the birds find new homes to colonize.
- Once this has occurred, the birds will then adapt to their new environments, and will often evolve traits to suit their new needs.
Given that through this process the birds evolve new traits and become a different species than the ancestor from which they originated, we can confirm that the factors most often associated with speciation in these areas are dispersal and colonization.
