Biodiversity in the young Hawaiian islands was low due to their isolation. This was highly advantageous to introduced species that could exploit the extremely specialized adaptations of the species there.

The cattle egret must continue to do what it already does best in order to compete and survive, with little opportunity for dramatic adaptations as is seen in the silversword.
