Rakiura Māori muttonbirding diaries: monitoring trends in tītī (Puffinus griseus) abundance in New Zealand
Rakiura Māori seek robust population monitoring to guide sustainable management of the annual take of muttonbird (tītī, Puffinus griseus), in southern New Zealand. Analyses of eight muttonbirder harvest records spanning ...
Using artificial nests to explore predation by introduced predators inhabiting alpine areas in New Zealand
Many bird species endemic to alpine New Zealand are now at critically low densities and restricted in range, making predator‐prey research difficult. We used artificial nests in the Borland Valley, Fiordland National Park, ...
Detection probability for estimating bird density on New Zealand sheep & beef farms
Factors influencing detection probability in line transect distance sampling were investigated to estimate the abundance of four common farmland birds on 12 sheep & beef farms in the South Island of New Zealand. Our primary ...
Satellite tracking of sooty shearwaters (Puffinus griseus) during their pre-laying “exodus” and incubation
Platform terminal transmitters (PTTs) using the CLS:Argos System were attached to adult sooty shearwaters (Puffinus griseus) at Taiaroa Head, South I, New Zealand. Three PTTs were attached to adults during the pre-breeding ...
Denning behaviour of ship rats (Rattus rattus) on Taukihepa, a seabird breeding island
Den sites of 14 ship rats (Rattus rattus) were located daily during the rat breeding season on Taukihepa (Big South Cape), a seabird island southwest of Rakiura (Stewart Island). In contrast to other New Zealand studies, ...
Changes in sooty shearwater (Puffinus griseus) abundance and harvesting on the Rakiura Titi Islands
We estimated the change in abundance of sooty shearwater (titi, Puffinus griseus) at six Rakiura Titi Islands, New Zealand, by comparing historical and recent surveys of the density of entrances to breeding burrows. We ...
Enhancing our heritage: Conservation for 21st Century New Zealanders: Ways forward from the Tahi group of concerned scientists
New Zealanders are constantly reminded of their degraded environment and the threatened status of their unique plants, animals and ecosystems. Instead of presenting these as symptoms of unsustainable living and the ...
Estimates of adult survival rate for three colonies of Sooty Shearwater (Puffinus griseus) in New Zealand
The Sooty Shearwater (Puffinus griseus), also known in New Zealand as tītī or muttonbird, is an abundant, long-lived, trans-equatorial migrant that breeds in colonies in the southern hemisphere during the austral summer ...
Estimating regional population size and annual harvest intensity of the sooty shearwater in New Zealand
Recent comprehensive survey data from multiple New Zealand offshore islands were combined with demographic population models to produce the first formal estimate of the total population of sooty shearwaters within New ...
