Birds have the greatest mobility of all terrestrial creatures and form the principal fauna of small oceanic islands, including Lord Howe, which has substantial breeding populations of land and seabirds. One hundred and eighty five species of birds have been recorded on Lord Howe Island, of which 32 are regular breeders today - fourteen species of seabirds, and eighteen species of landbirds. There are also a number of regular visitors that return at the same time each year on migratory paths.
