There are so many species that can be seen without having to go too far off the beaten path, that birdwatchers, botanists, ornithologists and wildlife experts simply love coming to the Chathams.
For the hardier and more scientific observers, the offshore islands and coastlines provide glimpses of even more rarer and nomadic species.
The birds featured in the slide-show are just a sample of the 50+ species that call these islands home. Some are just passing through on their annual migration. Others are more recent visitors and some 18 species are endemic to the islands.
Below is a selection of information about the bird life on the Chatham Islands.
Much more detail can be obtained from the publication Birds on the Chatham Islands produced by the Department of Conservation and available from the Department of the Hotel Chathams Gift Store.

The Chatham Island black robin is another bird saved from extinction in the late 1970s, when there were only 7 birds remaining on Little Mangere Island (Tapuaenuku) with "Old Blue" being the only remaining productive female. They are currently confined to Mangere Island with a population of some 250 birds.
The Chatham Island Taiko was thought to be extinct for over a century. There are currently around 30 breeding pairs and the entire known population is found in the southwestern forests of Chatham Island.
The Chatham Island red-crowned Parakeet occurs on the 4 largest islands, but their stronghold is on Rangatira Island (Southeast Island).
The Forbes Parakeet is one of New Zealand’s rarest Parakeets and is only found on Mangere Island.
The Chatham Island Warbler is abundant on Rangatira and Mangere Islands and present on Pitt Island and Southern Chatham Island.
The Chatham Island Tui were rarely seen on Chatham Island but are common on Pitt Island. However, after a successful relocation programme to the South Coast they are breeding on the Southern Coast of Chatham Island . They have also been seen recently on the Northern Coast (for the last 3 years) during summer feeding on the flowering Harekeke"
Chatham Island Mollymawk chicks have been transferred to Chatham Island to create a second breeding site to ensure the ongoing safety of the species.
The Parea (Chatham Island pigeon) is one of the worlds heaviest pigeons.
the Parea can be seen occasionally feeding during summer in the North of Chathams as well as their home areas in the South.
The Chatham Island Oyster Catcher population is now estimated to be more than 320 birds. DOC run an ongoing trapping programme during breeding season to save this vulnerable species.
The Chatham Island Petrel population was heading steadily towards extinction, but are now recovering thanks to some innovative management.
A recovery programme for shore plover has restored the populations on Rangatira and Mangere.
The Chatham Islands Blue Penguin are endemic to Chatham Islands and their breeding sites are widely spread amongst the islands. They appear to have benefited from the protection of other birds species on the islands, for example, the Torea (Chatham Island Oyster catcher)
The Chatham Island Shag is a black and white shag that can be found on the coast of Chatham Island, around Te Whanga Lagoon, Rabbit Island, North East Island and Star Keys.

The following lists of birds, presented in their preferred or usual habitat has been collated from public domain information, local knowledge and several publications, both print-based and electronic. This is not a complete list as there are several species now extinct not on the list, and several species that are accidental visitors, but present intermittently or occasionally.
