The sixth annual Garden Bird Survey starts on 30 June 2012. Anybody who can identify the common birds in their garden can participate. Simply watch out for birds in your garden for one hour (and just one hour) sometime between 30 June to 8 July, and for each species you encounter, record the largest number you see or hear at any one time. The reason for recording the largest number seen or heard at one time is so that individual birds are not counted twice.
