Background

At the RSPB I have worked on a wide variety of projects, including monitoring seabird numbers and breeding success on Orkney, estimating red kite numbers in Spain and co-ordinating national surveys of hen harriers in 1998 and 2004, black grouse in 2005 and upland birds during 2000-02. I have also researched factors influencing buzzard numbers in the West Midlands during 1994-96 and co-ordinated local surveys of ring ouzels in southern Scotland in 1997.

Since 1998, I have carried out a detailed demographic study of ring ouzels in Glen Clunie, Aberdeenshire in conjunction with my colleague Graham Rebecca. We have also fitted geolocators and GPS tags to breeding adults there since 2013, in order to discover more about migration routes, stopover sites and wintering areas.

Since 2006, I have lead on a project aimed at understanding the causes of ring ouzel declines at the UK scale, and completed my PhD on this topic at the University of Aberdeen in 2013.

In 2014, I lead a three-year project aimed at manipulating habitat conditions on two reserves in north England, in order to increase ring ouzel breeding numbers.

Finally, since 2015 I have been working on a project examining the home range size of pine martens using GPS tags at the Abernethy Reserve in the Cairngorm National Park.

Postfledging survival, movements and dispersal of ring ouzels (Turdus torquatus)

Recent evidence suggests that avian population growth rates may be constrained by low postfledging survival. Therefore, quantifying postfledging mortality and understanding the ecological factors that...
