Hot on the heels of two native bird species reappearing on Motutapu, one of New Zealand's best known songbirds - the bellbird - has also been rediscovered on the island. 

The return of the bellbird, after more than 100 years' absence, follows one of New Zealand's largest ever island pest eradication programmes on Motutapu and Rangitoto Islands last year.

Kakariki (parakeets) began breeding on Motutapu in December, and pateke (brown teal) were spotted on the island in early February.

The sighting of bellbirds comes as more than 80 international and national delegates gather in Auckland this week at a workshop led by the Department of Conservation on tackling threats to wildlife on islands around the world.

'Helping Islands Adapt' workshop Chair, Dr Spencer Thomas from Grenada, a councillor on the global conservation network, IUCN, said the return of the bellbird and other native species to Motutapu is hugely significant for all conservationists working with vulnerable island ecosystems.

"It is precisely these sorts of successes that show the importance of island nations sharing strategic and technical skills in the fight to keep their native species alive.

"New Zealand has had some great successes in breathing life back into some of its islands. The UN has declared 2010 the International Year of Biodiversity - by working together we can improve the chances of survival for threatened wildlife and plants on islands around the world.

No rats, mice or stoats have been detected on Motutapu and Rangitoto since the last of three aerial drops of bait containing brodifacoum in August last year. Trapping, hunting and spotlighting to ensure the eradication of feral cats, hedgehogs and rabbits will continue for at least another year.

"It's likely that these bellbirds have come from rodent-free Rakino Island, as it's less than two kilometres from Motutapu," says Richard Griffiths, project manager for the Department of Conservation's pest-eradication project on Rangitoto and Motutapu.

Neil Lorimer, a volunteer for the Motutapu Restoration Trust, was the first to hear one of the bellbirds. He thought at first it might be a tui, but it didn't sound quite right. A few days later the mystery was solved.

"Three other volunteers and I were doing some weeding when the bellbird started singing. This time I managed a good sighting," he says.

Mr Lorimer says the members of the Trust are delighted that three native bird species have returned to Motutapu in just four months.

"It's a credit to all our volunteers who have planted the 500,000 trees that make Motutapu suitable for our native forest birds," he says.

The bellbird, or korimako, has been almost completely absent north of the Bombay Hills since the 1860s. In the Hauraki Gulf Marine Park they survived on offshore islands such as Tiritiri Matangi and Hauturu/Little Barrier. In 2005 they made their own way to Rakino Island and the Tawharanui Open Sanctuary - a predator-free mainland island.

"Now that bellbirds have been seen on Motutapu, there's a real prospect that they may soon start turning up in Aucklanders' backyards," says Mr Griffiths.

He says that visitors to the islands can help these new arrivals survive by checking their boats and gear for rodents before they depart.

"We want to make sure that pests aren't inadvertently reintroduced," he says.

Background information


  • The bellbird is unique to New Zealand, occurring on the three main islands and many offshore islands. Once common, their numbers declined sharply during the 1860s in the North Island and 1880s in the South Island, about the time that ship rats and stoats arrived.

Rangitoto/Motutapu restoration programme

  • With stoats, cats, hedgehogs, rabbits, mice and two species of rat targeted across 3,842ha, the ambitious Rangitoto/Motutapu restoration programme is one of the most complex pest eradications ever attempted.
  • If the eradication is successful, Rangitoto and Motutapu will become the largest pest-free island sanctuary in the Hauraki Gulf Marine Park, and will increase the total area within New Zealand that is pest-free by 15%.
  • While we won't know for sure whether the project has been successful until June 2011, the initial signs are very promising.

‘Helping Islands Adapt' workshop

  • The workshop is being held at the Hyatt Regency, Auckland from 11 – 16 April. Participants include representatives from a number of nations and island states along with government and international conservation groups.
  • The workshop is designed to help strengthen and mobilise capacity on islands across the globe to address the threats posed by invasive species.  
  • The primary focus is on institutional relations and collaboration among key stakeholders.
