Colourful parakeet back in New Zealand bay after absence of more than 30 years
People urged to contribute to pest control efforts to help boost red-crowned parakeet numbers
One of New Zealand’s most colourful native birds is back in the Bay of Islands for the first time in more than 30 years.
Forty kakariki, or red-crowned parakeets, were released yesterday on Moturua, part of a pest-free chain of islands between Russell and Cape Brett.
The birds were caught on Little Barrier, kept in a purpose-built aviary, then flown to Moturua by helicopter in individual bird boxes.
More than 50 people travelled to the island to see conservation history being made, with many getting a chance to release a bird.
The striking green and red birds are the latest species to be returned to the islands as part of Project Island Song, a joint effort by community group Guardians of the Bay, the Department of Conservation and local hapu Ngati Kuta and Patukeha to rid the eastern Bay of Islands of pests and restore the original flora and fauna.
Dean Baigent-Mercer, conservation advocate for Forest and Bird, said the return of kakariki was “hugely significant”.
“They’ve become extinct on the Northland mainland in our lifetime. Occasionally they do fly over from the Poor Knights or the Hen and Chickens, but as far as we know they haven’t nested on mainland Northland since the early 1980s.”
In the 1880s kakariki were so common their feathers were used to stuff mattresses, he said.
Unlike other birds re-introduced to the islands, kakariki could easily fly to the mainland so they could become a common sight in backyards around the Bay, travelling in flocks and making a “cheerful chatter”. On the mainland, however, they would be vulnerable to predators.
“So it’s up to all of us if we want kakariki back in our everyday lives,” he said.
The mainland Bay of Islands had a chain of pest control projects from Purerua Peninsula in the north all the way around to Rawhiti. However, there were still gaps, and everyone could contribute by trapping rats and possums in their own gardens, or by joining a pest control project targeting the four worst offenders - possums, rats, stoats and feral cats.
That not only benefited kakariki but also boosted numbers of tui, grey warblers, kukupa and ruru (moreporks).
“We have only the crumbs of what there used to be ... With pest control we can increase the number of birds that are around and bring back the ones we’ve lost.”
Kakariki made their nests in holes in trees or banks and could be prolific breeders, laying several clutches of eggs in spring and summer with three to nine eggs per nest.
That meant numbers could increase quickly if predators were absent, as shown by saddlebacks on Urupukapuka and Moturua. They were only re-introduced in 2015 but were “absolutely everywhere” on the islands.
