| Name |
|
| John Calladine |
| Position |
| Research Ecologist, BTO Scotland |
| Role |
| Developing, managing and undertaking research in or relevant
to Scotland. I have particular remit for projects that involve
ringing, those involving upland, moorland and marginal upland
habitats, and those involving the effects of habitat change. |
| Qualifications |
BSc (Hons) Ecology, University of Lancaster, 1979-1982
MSc (by research) ‘Colony attendance, nest site selection
and breeding performance in the Herring and Lesser Black-backed
Gull: implications for conservation management’, University
of Stirling, 1993-95. |
| Research Interests/Responsibilities |
| Recent and current research includes: studies
on movements of farmland birds in winter; reviews of populations
and impacts of predatory birds and the ecology of urban gulls
in Scotland; development of methods for surveying and monitoring
Short-eared Owls; development of volunteer-based monitoring
of montane birds (Ptarmigan in particular); survey and monitoring
of moorland and woodland birds. I am particularly interested
in ‘uplands’ and how land management affects bird
populations. |
| Other Information |
