Vatu-i-Ra Island in Ra could very well be the last bastion of hope in bringing up the numbers of the threatened petrel, locally known as the kacau ni Gau.
Vatu-i-Ra Island was declared an important bird area by bird conservation organisation Birdlife International and is home to nine bird species.
It is also where the latest attempts to boost petrel numbers are taking place.
The island traditionally belongs to the villagers of Nasau in Ra. Nasau villager Akuila Qionibaravi explains they are hoping the kacau will come to nest there.
"Birdlife International installed a solar powered machine to imitate the call of the kacau from six in the night to six in the morning, as this is when the kacau is out flying," he said.
Mr Qionibaravi said there were in-built underground nesting sites by the machine to encourage the kacau to nest on the island.
He said the island had been cleared of rats and other pests that were posing a threat to birdlife thus ensuring safe breeding environment for birds.
Mr Qionibaravi said the villagers of Nasau had always known that Nasau was alive with birdlife and through research conducted by Birdlife International had come to appreciate the importance of the island.
He explained that apart from being a site where they wanted kacau to breed, the island also had the highest number of Black Noddys in the South Pacific.
He added while the villagers had worked hard with non-government organisations to keep the island free of humans, they still faced problems.
"Some people are still coming but in the meantime we have been reporting them to police and we are taking photos of boats that we see illegally fishing in this area to police," he said.
