I have been interested and working with hihi since I was involved with establishing the Tiritiri Matangi island population through translocation in 1995. I am now employed as a Research Fellow at the Zoological Society of London and have been here since 2004. My research is multi-disciplinary and focusses on small population biology and management. I use decision science to assist in planning hihi management and drive our applied research with this species and have experience in molecular and behavioural ecology, wildlife health and nutrition and reintroduction biology.

Published in:Â Philosophical Transactions of the Royal Society of London Series B Authors: Kate M. Richardson, Elizabeth H. Parlato, Leila K. Walker, Kevin A. Parker, John G. Ewen and Doug P. Armstrong Abstract: There is growing recognition that variation in animal personality traits can influence survival and reproduction rates, and consequently may be important for wildlife […]
Published in: Conservation Science and Practice Authors: Julia Panfylova, John G Ewen and Doug Armstrong Abstract: Structured decisionâ€making (SDM) has become popular in natural resource management but has been underused in reintroduction programs. We illustrate how conservation managers can use SDM to guide management decisions after initial reintroduction, when data are still limited and uncertainty […]

Ella Wilks-Haper reports.
Published in: Evolutionary Applications Authors: Pierre de Villemereuil, Alexis Rutschmann, John Ewen, Anna Santure & Patricia Brekke Abstract: Many bird species have been observed shifting their laying date to earlier in the year in response to climate change. However, the vast majority of these studies were performed on nonâ€threatened species, less impacted by reduced genetic […]
Published in: Current Biology Authors: Pierre de Villemereuil, Alexis Rutschmann, Kate Lee, John Ewen, Patricia Brekke & Anna Santure Abstract: Threatened species face numerous threats, including future challenges triggered by global change. A possible way to cope with these challenges is through adaptive evolution, which requires adaptive potential. Adaptive potential is defined as the genetic […]
One of New Zealand’s rarest native birds has shown how threatened species everywhere are facing a tougher time adapting to our fast-changing planet. Scientists have already shown how domesticated animals and wild creatures that aren’t threatened can adapt to different environments if they’re flexible enough, could shift ranges, or can simply evolve. But new research […]
A record number of hihi or stitchbird have fledged on pest-free Tiritiri Matangi Island in the Hauraki Gulf Marine Park during the latest breeding season. Hihi breeding on Tiritiri Matangi starts in late September and runs until February. This breeding season 252 new birds were added to the hihi population on Tiritiri Matangi. That beats […]
Published in: Methods in Ecology and Evolution Authors: Oliver C. Metcalf; John G. Ewen; Mhairi McCready; Emma M. Williams and J. Marcus Rowcliffe Abstract: Conservation translocations are an important tool in wildlife management, but monitoring of translocations has traditionally suffered from a lack of techniques for effective postâ€release monitoring. Increasing understanding of postâ€release movements is vital in improving the success of […]
5th February 2019 The hihi team pioneer new method of monitoring hihi reintroductions by listening in on bird ‘conversations’ Remote recording devices used to ‘eavesdrop’ on a reintroduced population of one of New Zealand’s rarest birds have been heralded as a breakthrough for conservation. Scientists from ZSL, Imperial College London and conservationists from the Rotokare […]
