Good news from the Landsborough Valley

Postby David Riddell » Tue May 14, 2019 8:57 am

Just seen this:
The once rare mohua is now the most common native bird in south Westland's Landsborough Valley.

Only 14 of the birds, also known as the yellowhead, were counted when monitoring there began in 1998. But after predator control in the valley, 444 birds were noted during the Department of Conservation's last count in November.

Native bird numbers overall have doubled in the valley in the past 21 years.

Department of Conservation principal science advisor Colin O'Donnell said the most recent data from the long-term study of native birds showed seven species were increasing in numbers, four remained stable and two had declined.

"For the first time in 21 years, mohua have become the most common bird counted, which is what they would have been in this valley prior to European settlement," Dr O'Donnell said.

"The results are exciting because year by year we're seeing a re-balance of the valley's birdlife and don't know when population limits will be reached."

Numbers of mohua or yellowhead, tūī, bellbird or korimako, brown creeper or pīpipi, rifleman or tītitipounamu, grey warbler or riroriro and kākāriki or yellow-crowned parakeet had steadily increased over the past 21 years.

Kākā, tomtits/ngirungiru, fantails/pīwakawaka, and kererū/wood pigeons had stable populations that had not declined as would have been expected without predator control.

It's great - but it's a sobering thought that areas like these are only ever one big beech mast away from being back to square one....

Cheers Jim
