About Surveys

The BTO has considerable expertise in the design, implementation and analysis of a range of projects from intensive studies to extensive surveys. It runs a number of national, annual surveys through its volunteer network to monitor the status of many of our bird species across a range of habitats. Thus, the BTO possesses an unrivalled historical database of bird populations and distributions for the UK. Surveys are organised and the results analysed by a team of professional scientists based at the Trust's headquarters in Thetford. This unique partnership between volunteers and professional staff makes our work extremely cost-effective for our funding agencies.
