When new islands appear above the surface of the ocean their colonization usually follows a standard pattern. The initial living things to grow there are plants, germinating from seeds and spores borne on the wind. The first animals are always insects, again because they can be blown on the wind from distant continents. The first vertebrates to arrive are the birds and pterosaurs, winged vertebrate creatures that are able to fly over the intervening ocean areas. Very often these winged creatures give up their powers of flight and take up a ground-dwelling existence, eating the plants and the insects on an island that is free from any dangerous predators.
