Breeding Bird Survey (BBS)

The BBS is the main source of population trend information about the UK’s widespread birds – an important indicator of the health of the countryside. Survey results also feed into Breeding Birds in the Wider Countryside reports.

Getting Involved

The survey involves two spring visits to a local 1-km square, to count all the birds you see or hear while walking along two 1-km transects within the square. Each visit should take less than two hours, and we recommend that you make a reconnaissance visit to set up or check your transect route and access, and complete a habitat recording form. We are also interested in mammal records from your square, and you can even visit your square later in the season to survey for butterflies with the Wider Countryside Butterfly Survey.

Skill level: ability to identify common birds by sight and sound. All birds encountered during the survey should be recorded.

We have a number of vacant 1km squares that are currently available for new volunteers to take on.

Further information about taking part is available from the BTO website.

Please contact Wayne if you’d like to take part.
