Kapiti Island is a small island just 5km off the coast of Wellington. It is roughly rectangular being 8km long and 2km wide.
The island is home to a number of native birds, mostly re-introduced. These include takahe, North Island kōkako, brown teal, stitchbird(hihi), North Island saddleback (tieke), tomtit (miromiro), fantail (piwakawaka), morepork (ruru), weka and North Island robin (toutouwai). The brown kiwi and little spotted kiwi were released on the island between 1890 and 1910, and the island is now the stronghold for the latter species. Rat eradication has led to increases in red-fronted parakeets, North Island robin, bellbirds, and saddlebacks, and the island is considered one of New Zealand‘s most important sites for bird recovery, as well as a major breeding site for sea birds. In April 2005, the critically endangered short-tailed bat was introduced to the island from a threatened population in the Tararuas, providing them with a separate, safer habitat. – Wikipedia
