Modelled relative abundance of bird species in Britain and Ireland 2007-2011

This data package describes the modelled relative (not absolute) abundance of Carrion Crow (Corvus corone), Magpie (Pica pica), Buzzard (Buteo buteo) and Kestrel (Falco tinnunculus) in Britain and Ireland.

This was used to produce Bird Atlas 2007-2011 maps of relative abundance at a tetrad (2x2km) resolution. 

Acknowledgement: These data originate from the Bird Atlas 2007–11 project which was run by the BTO in partnership with BirdWatch Ireland and the Scottish Ornithologists’ Club. We are grateful to the thousands of volunteers who undertook and organised the fieldwork for the atlas.

Please refer to the metadata for a more detailed description, and for information on dataset usage.

v1.2 update: added Buzzard (Buteo buteo) and Kestrel (Falco tinnunculus). Changed file structure, creating one file per season (B = Breeding, W = Winter)
