Dispersal across the ocean is difficult for most land [[animal]]s, and Oceania has relatively few indigenous land animals compared to other realms. Certain types of animals that are ecologically important on the continental realms, like large land [[predator]]s and grazing mammals, were entirely absent from the islands of Oceania until humans brought them. [[Bird]]s are relatively common, including many [[seabird]]s and some species of land birds whose ancestors may have been blown out to sea by storms. Some birds evolved into flightless species after their ancestors arrived, including several species of [[rallidae|rails]]. A number of islands have indigenous [[lizard]]s, including [[gecko]]es and [[skink]]s, whose ancestors probably arrived on floating rafts of vegetation washed out to sea by storms. With the exception of [[bat]]s, which live on most of the island groups, there are few if any indigenous non-marine [[mammal]]s in Oceania.
