The Kura on Ātiu – the 10th anniversary

The Kura on Ātiu – the 10th anniversary

Ten years ago, on 24th April 2007, Air Rarotonga flew 27 Kura (Rimatara Lorikeets, Vini kuhlii) on a direct flight from Rimatara to Ātiu, where the bird had been absent for 200 years.

This was the first transboundary reintroduction of a bird in the Pacific and was reported by more than 130 major news outlets around the world. TVNZ showcased the event with Greg Parker’s “Spirit of the Queen” documentary, which is on YouTube at www.youtube.com/kokamedia.

In pre-historic times the Kura were found throughout the Southern Cooks and eastward to Rimatara and Rurutu in French Polynesia. It had been lost on all islands, except Rimatara, by the over-harvesting of its red feathers for personal adornment.

The purpose of the reintroduction project was to establish a second population to maintain the Kura within its former natural range in case it were devastated on Rimatara by an invasion of Ship Rat(Rattus rattus). The Natural Heritage Trust and MANU, the Ornithological Society of French Polynesia, took six years to negotiate approvals with government agencies and the Rimatara community, which gave the birds into the care of Rongomatane Ariki and the Ātiu community.

The Bottle Gourd (Hue, ‘Ue) of ancient Polynesia

The Bottle Gourd (Hue, ‘Ue) of ancient Polynesia

Gerald McCormack, CINHT

The ancient Polynesians brought many plants into Polynesia from Melanesia and Asia. Was this the source of the Bottle Gourd or did it come from the Americas?

In the Cook Islands there are 39 useful, or formerly useful, plants that were purposefully introduced by the Polynesian settlers before contact with Europeans. In addition there are 17 weedy plants that were probably accidentally introduced in those ancient times, although some are used in herbal medicines and might have been purposeful introductions. In total: about 56 Polynesian Introduced plants.

Among the Polynesian Introduced plants there are two that probably came from the Pacific coast of South America: the Sweet Potato (Kūmara, Kūara, Ipomoea batatas) and the Bottle Gourd (Hue, ‘Ue, Lagenaria siceraria).

Frigatebirds – Our Vulnerable Pirates

Frigatebirds – Our Vulnerable Pirates

Great Frigatebird Courtship – Donna O’Daniel

Gerald McCormack, CINHT

Frigatebirds are the largest seabirds residing in the Cook Islands, with wingspans of 180-220cm. They are uniformly black above, and black or black with a white breast below; their wings are long, angled, and sharp tipped; their tails are long, and deeply split into two sections. They do not nest on Rarotonga, or on any inhabited Southern Group island, although they often soar over the coast of inhabited islands when there is a storm at sea. As a result they are sometimes called Storm Birds or Hurricane Birds. It is not clear why frigatebirds congregate at islands during storms, but it is probably because they find flying at sea more difficult and if they land on the water they usually die.

The Status of Cook Islands Birds -1996

The Status of Cook Islands Birds -1996

Gerald McCormack, CINHT

The Cook Islands is fifteen small islands (total land area 240km²), scattered over an area approaching the size of Western Europe, in the tropical South Pacific. Although the 18,000 residents, almost all Polynesian, carry New Zealand passports, the country has been internally self-governing since 1965, and is independently responsible for all environment matters.

Two divisions of Government are specifically concerned with the environment: (1) the Environmental Service (formerly the Conservation Service) implements the environment act, with a special emphasis on Environmental Impact Assessment; and (2) the Natural Heritage Project undertakes research, and prepares publications, to integrate traditional and scientific knowledge on all aspects of the environment. The latter project, formalised in 1990 by the Prime Minister, Sir Geoffery Henry KBE, is unique in the South Pacific.

The limited availability of specialist staff, and of financial resources, has meant that overseas volunteers and funding have been of fundamental importance in monitoring and maintaining the inherently fragile terrestrial and coral-reef ecosystems. Land is under family-inherited ownership and, although it cannot be sold, a small amount is leased to the Government and to non-family people.

The fifteen islands divide socially and physically into a Northern Group of six islands and a Southern Group of nine islands. The five atolls and one sand-cay of the Northern Group, support extensive Coconut Palm plantations for a fickle copra industry. The only resident landbird is the Pacific Pigeon (Rupe, Ducula pacifica), which lives on three atolls, feeding mainly on the fruits of the indigenous Beach Gardenia(Ano, Guettarda speciosa).

Rare Seabirds on Aitutaki and Rarotonga

Laughing Gulls

Adults (right & top), Juvenile (bottom) – Cook Islands, Aitutaki – Gerald McCormack

Seagulls are such common seabirds in New Zealand, Australia and America, that it always comes as a surprise for visitors to find no seagulls in the Cook Islands, assuming they ignore the two plastic ones at the Deli in Foodland. Although seagulls seem like the most adaptable scavengers we can imagine, they have not managed to establish themselves on the islands of tropical Polynesia. The nearest island to have resident seagulls is New Caledonia.

It was therefore surprising when people reported a dull brown seagull at Avatiu and at Muri in April 1992. It stayed a few weeks and then disappeared. Since then a similar type of seagull has been reported during the early months of 1995, 1997 and 1998. These birds were all first-year Laughing Gulls (Leucophaeus atricilla). This means that on each occasion it was a different bird that was seen, and only on one occasion did two birds visit together.
