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: Oecologia Authors: Elizabeth H. Parlato, John G. Ewen, Mhairi McCready, Kevin A. Parker & Doug P. Armstrong Abstract: A key goal of ecological research is to obtain reliable estimates of population demographic rates, abundance and trends. However, a common challenge when studying wildlife populations is imperfect detection or breeding observation, which results in […]
Check out the latest from the Hihi Recovery Group and Hihi Conservation Charitable Trust. It has been another big year and we report on our progress recovering this most amazing bird.
Published in: Proceedings of the Royal Society B: Biological Sciences Authors: Victoria R. Franks, John G. Ewen, Mhairi McCready and Rose Thorogood Abstract Early independence from parents is a critical period where social information acquired vertically may become outdated, or conflict with new information. However, across natural populations, it is unclear if newly independent young […]
We are very happy to share that Caitlin has submitted her PHD. This is a truly global PHD effort with a focus on hihi dietary variation. It included field study on multiple hihi populations (Tiritiri Matangi, Rotokare, Bushy Park Tarapuruhi and Zealandia) and even some sites where we hope to see hihi in the future […]
Published in: Evolutionary Ecology Authors: Alexis Rutschmann, Pierre de Villemereuil, Patricia Brekke, John G. Ewen, Neil Anderson and Anna W. Santure Abstract: In heterogeneous habitats, individuals sharing a larger part of their home-range are also likely to live in a very similar environment. This ‘common environment’ effect can generate phenotypic similarities between neighbours and lead to the […]

Published in: Animal Conservation Authors: Victoria R. Franks, Caitlin E. Andrews, John G. Ewen, Mhairi McCready, Kevin A. Parker and Rose Thorogood Abstract: Reintroductions, essential to many conservation programmes, disrupt both abiotic and social environments. Despite growing recognition that social connections in animals might alter survival (e.g. social transmission of foraging skills, or transmission of […]
Published in: Animal Behaviour Authors:Â Victoria R. Franks, John G. Ewen, Mhairi McCready, J. Marcus Rowcliffe, Donal Smith and Rose Thorogood Abstract: Animal sociality arises from the cumulative effects of both individual social decisions and environmental factors. While juveniles’ social interactions with parents prior to independence shape later life sociality, in most bird and mammal species […]
Twenty female and 20 male hihi were released on Friday 3rd June by members of Auckland Council, Hihi Conservation Charitable Trust, NgÄti Manuhiri, the Navy and Shakespear Open Sanctuary Society Incorporated (SOSSI) onto Defence Force land within the park. For full coverage of the release, along with a really neat video please see the media […]
