The Cambridgeshire Bird Atlas 2007–2011 provides a comprehensive overview of the summer and winter distribution and abundance of birds in the county. It contains 500 detailed maps showing where 167 bird species can be found breeding or wintering. Facing the maps are expert species accounts interpreting the maps and placing them in historical and national context. The atlas was compiled from data collected for the British Trust for Ornithology's national UK Bird Atlas 2007–2011. That project, perhaps one of the largest examples of 'citizen science' ever undertaken, involved over 40,000 enthusiastic volunteer surveyors over four summers and winters.
For the Cambridgeshire Bird Atlas, almost a thousand contributors provided details of the birds they saw, either during timed visits to specific Ordnance Survey squares, or as roving records through the seasons. Species were mapped at the scale of 2 km squares (closer detail than for the national atlas); there are just short of one thousand such squares within the county boundary. Records were received from 90% of these squares.
It is hoped that the Atlas will be used by schools, local government, and other agencies, institutions and organisations involved with planning, land-use, ecology, the environment and nature conservation in Cambridgeshire and Peterborough.
The atlas is authored by Louise Bacon, Alison Cooper, Hugh Venables and can be purchased from the Cambridgeshire Bird Club or Amazon.
