How to take part
Fieldwork for the national atlas is now complete. There are c20 local atlas projects continuing for another year or more - please have a look where these are and see if you can help.
There are two ways to help:
Timed Tetrad Visits - record all the birds you see and hear in a 2km x 2km square. Visit for an hour or more in the winter and breeding season.
Roving Records - any bird, anytime, anywhere. If you see it, record it, and we'll map it.
You can request a square to cover for Timed Tetrad Visits without registering for Bird Atlas Online. However, we strongly encourage you to register - then you view maps of your tetrads, submit your records online, and see how results develop.
Any problems, do contact birdatlas [at] bto [dot] org for help.
