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 […]

The highlight of this season for hihi conservation has been establishing a seventh population, hihi have once again been returned to the mainland; this time to Taranaki. After spending the breeding season on Tiritiri Matangi it seemed like an obvious progression for me to move to Taranaki with the birds. To quote John, I have […]

Please join us in a short history of hihi conservation and the central role that Tiritiri Matangi island has played in the return of hihi to parts of their former range. Our story focusses on these most colourful and charismatic of New Zealand’s endemic birds. We share their history, some of their extreme behaviours and […]
I’m a second year PhD student at the University of Cambridge and Zoological Society of London, researching hihi social behaviour in the population on Tiritiri Matangi Island. One of the most common questions I’m asked by visitors to the island is “what’s a researcher from the UK doing working with a bird on an island […]

A study conducted between research partners at the Zoological Society of London (ZSL) in the United Kingdom and the University of Auckland in New Zealand has revealed the importance of single males in small, threatened populations. Results from a study of endangered New Zealand hihi (Notiomystis cincta), were recently published in the research journal Evolutionary […]
