B) A random large group of a bird population migrates to an island and then returns to breed.
C) A selected small group of a bird population migrates to an island and then returns to breed.
D) A random small group of a bird population migrates to an island and does not return to breed.
E) A random large group of a bird population migrates to an island and does not return to breed.
