BTO Garden BirdWatch

The British Trust for Ornithology monitors the changing fortunes of those birds that use our gardens through the BTO Garden BirdWatch. The project involves more than 16,000 garden birdwatchers, all collecting simple information on the birds using their gardens throughout the year. This information also enables us to find out how birds use different types of gardens and how this use varies across Britain and Ireland. Garden BirdWatch is the largest year-round study of garden birds (and other garden wildlife) anywhere in the World.
