Chris Thaxter

Position

Research Ecologist, Wetland and Marine Research

Role

My principal role is undertaking research into changes in the abundance and foraging behaviour of seabirds and waterbirds in relation to both man-made impacts and environmental processes. I take a central role in conducting and developing marine research projects at the BTO.

Qualifications

BSc (Hons) Geography, University of Reading, 1999-2002.
MSc Wildlife Conservation and Management, University of Newcastle, 2002-2003.
PhD Foraging and Breeding Ecology of Guillemots and Razorbills, University of Leeds, 2005-2008.

Research Interests / Responsibilities

My post entails a broad spectrum of research projects. Current key research includes the use of bird-borne logging devices to understand foraging behaviour, distribution and interaction of seabirds with offshore windfarms.  I recently completed a review into the foraging ranges of UK breeding seabirds with a view to such data being used as a preliminary tool in identifying candidate marine protected areas (MPAs).  Recent work has also explored the use of sea-watching data for monitoring the non-breeding movements of species past our coasts.  I am also involved in environmental impace assessments of renewable energy developments on waterbird and seabird populations.  I am involved in numerous other projects investigating the impacting of offshore developments on birds, and have previously completed a review of the use high definition imagery technology for surveying seabirds and marine mammals.

Other Information

I have a broad interest in the natural sciences with a research background in seabird ecology.  I have a keen interest in seabird foraging behaviour, population ecology, and life-history environment interactions.  I am an ordinary Member of the Seabird Group, and am a guest lecturer as part of BSc and MSc University modules.
