New Zealand is an island nation composed mainly of two large landmasses, the South Island and the North Island. Because these islands have remained isolated from other continental landmasses for approximately 52 million years, the country developed an exceptionally distinctive ecosystem.

Apart from humans and the species they later introduced, the only native terrestrial mammals in New Zealand are bats belonging to the family Mystacinidae. As a result, birds have long played a dominant ecological role in the structure and function of New Zealand's ecosystems.
