BTO Research Report 715 cover

Investigating wader breeding productivity in the East Cairngorms Moorland Partnership Area using collaborative methods

2019 | Jarrett D., Calladine J., Milner J., Wernham C., Wilson M.

Breeding wader populations have declined significantly in recent decades in the UK. During this time, areas of moorland managed for grouse shooting and adjacent areas of rough pasture have been identified as persisting strongholds.

Peer-reviewed papers
Peregrine, by Philip Croft / BTO

The breeding population of Peregrine Falcon Falco peregrinus in the United Kingdom, Isle of Man and Channel Islands in 2014

Breeding Peregrines on the up thanks to growth of lowland populations

2018 | Wilson, M. W., Balmer, D. E., Jones, K., King, V. A., Raw, D., Rollie, C. J., Rooney, E., Ruddock, M., Smith, G.D., Stevenson, A., Stirling-Aird, P.K., Wernham, C. V., Weston, J. M. & Noble, D.G. Bird Study

The return of breeding Peregrines to former haunts, and the colonisation of urban sites such as industrial buildings and cathedrals, has not gone unnoticed by birdwatchers. It is only now, however, with the publication of the results from the latest national Peregrine survey, that we can put figures on the changing fortunes of this stunning bird of prey.

Scanning for Scottish bats

2017 | Newson, S.E., Evans, H.E., Gillings, S., Jarret, D., Raynor, R., Wilson, M.W. Biological Conservation

The decline of a population of farmland breeding waders: a twenty-five-year case study

Waders in decline in Strathallan, Scotland

2017 | M.V. Bell, Calladine, J. Bird Study

The breeding populations of many different wader species are in decline across the globe, and there is an urgent need for information on how such changes in land management, particularly within farmland, may affect breeding waders. This study by a long-term BTO volunteer explores wader decline in Strathallan, Scotland over a period of 25 years.
