Passerine birds are the most successful group of birds in Antarctica. Representatives of Suboscines suborder characteristic for New World live here. They belong to families of ovenbirds and tyrant flycatchers (and to family of false swallows descended from tyrant flycatchers). Tiny flightless birds of mousebird family, descended from South American tapaculos, are endemics of Antarctic Region. They lead nonmigratory way of life and replace rodents absent at the continent. From the number of songbirds Antarctic Region is inhabited by pipits, buntings, wrens and New World warblers. At some subantarctic islands birds of families of Old World warblers and Old World flycatchers (and close families), coming from Meganesia and New Zealand, live. The largest passerines of Antarctica are representatives of icterid family (grackles and New World orioles). They occupy niches of corvids and even birds of prey (for example, falcon grackle). Also in summer in Antarctica one kind of larks nests � it is a descendant of European species introduced by people to New Zealand. It winters in New Zealand.
