Breeding and wintering bird distributions in Britain and Ireland from citizen science bird atlases

Since fieldwork started in early 1968, bird atlases have been a periodic feature of the bird surveying landscape in Britain and Ireland. They have provided countless hours of enjoyment for their volunteer participants and yielded data crucial for conservation and research activities. BTO and our collaborators have been working with these data for many decades, but now BTO is taking the bold step of making the full archive of distribution data freely available for anyone to use, as described in a new ‘data paper’ published in the journal Global Ecology and Biogeography.
