What is the atlas?
Atlases give us the opportunity, about every 20 years, to visit all 10-km squares in Britain and Ireland and tell us what is there and approximately how common they are. It’s a snapshot of bird distribution and abundance in time. Atlases have provided vital information for bird conservation. One of the important findings from the last breeding atlas in the late 1980s was the widespread range contraction of many of our farmland birds. This led to detailed research into the causes of these declines.
What can I do to help?
Thousands of birdwatchers will take part in fieldwork throughout the Britain and Ireland. We need all your records – whatever you see, whenever, wherever! There are two components to the fieldwork: Timed Tetrad Visits (TTVs) and Roving Recorders. TTVs involve two visits in the summer and two in the winter to a tetrad (2 km x 2 km square). Each visit is for a minimum of one hour and the idea is to record species you see and hear along with numbers, so we can calculate the relative abundance of species in the 10-km squares. We are aiming to cover a minimum of eight tetrads in every 10-km square (there are 25 tetrads in a 10-km square). Of equal importance are general birdwatching visits to 10km squares (Roving Recorders) where the aim is to compile a species list of everything you see and hear.
How do I get involved?
The Atlas needs both casual observations that can be submitted online via Birdtrack [1] and specific visits over the seasons.
