Ten of the region's endemic birds can be seen in Tonga and these include two of it's own endemics, the Tongan Megapode which is restricted to the isolated Nuiafo'ou and the Tongan Whistler which is found only in the Vava'u Group.
The Kingdom of Tonga consists of about 170 islands of which only 36 are inhabited; four main island groups, the outlying northern Nuias'; Vava'u; Ha'apai and the southern Tongatapu Group. Running almost the length of the archipelago on the western side is a string of active and dormant volcanoes such as Nuiafo'ou, Toku, Fonualei, Late, Kao, Tofua and 'Ata. To the east are the older, coralline limestone covered islands.
The original vegetation of Tonga was tropical rain forest – today this has been almost completely lost, throughout the Kingdom. Only small remnants remain on Tongatapu, some of the Vava'u islands and on 'Eua. The 449 ha 'Eua National Park is the sole terrestrial biodiversity protected area in the Kingdom. The Tongan Government is currently considering a proposal to declare the islands of Maninita and Taula in the Vava'u Group as protected areas as both these islands are important seabird nesting sites.

'Eua National Park
The southern cliffs and forests are perhaps most rewarding, as many of the seabirds and most of the forest birds can be seen here. Among seabirds, Grey Noddies are the most unusual species to be encountered. Brown Bobbies and Brown Noddies breed on the cliffs and White Terns and White-tailed Tropicbirds are common over the sea as well as above the forest. Most of 'Eua's land birds are seen in this area such as the introduced Red-breasted Musk Parrots, Pacific Pigeons, Crimson-crowned Fruit-doves, Polynesian Trillers, Wattled Honeyeaters, Polynesian Starlings and the White-collared Kingfisher.
Maninita & Taula
The remote southern islands of Maninita and Taula are important seabird nesting sites with 19 species of birds recorded on or around the islands. There are 3 species of resident breeding land birds – the Wattled Honeyeater, Banded Rail and White-collared Kingfisher. 5 seabirds nest on the islands – Black and Brown Noddies, White Terns, Black-winged Petrels and the Red-footed Booby. In 2002, with assistance from NZAid, a rat eradication programme was successfully conducted on Maninita and Taula.
The ultimate destination for birders in Tonga is the remote northernmost island of the archipelago, Nuiafo'ou, home of the critically endangered endemic Tongan Megapode. This extremely interesting and beautiful island can now be accessed by air. However, bookings well in advance are essential as arrangements need to be made with the villagers from Angaha to organize boat transport to the islands in the caldera to see this extremely rare bird.
Tongatapu - Sopu Mudflats
These fringing mudflats and patches of Mangroves are located west of Nuku'alofa. This is a good site for waders and Pacific Black Duck, Reef Egrets, Black-naped and Crested Terns are normally seen. Both White-faced and Mangrove Herons have been observed here, neither of which is a confirmed breeder in Tonga. On the coast here the ubiquitous White-collared Kingfisher is common and Pacific Swallows, a rare species in Tonga, may be seen.
Tongatapu - Tongan Wildlife Centre
Originally established by the German based Brehm Fund for International Bird Conservation and now run by the Tongan Wildlife Trust. The Centre is actively involved in captive breeding – wild releasing, and in translocation between islands of threatened Tongan wildlife.
