A survey of breeding birds, conducted using 3 visits over 3 months to a random 1km square.

Aims:

  • to gather detailed information on all species that breed during the summer within the BOS
  • to record the number (abundance) and distribution of breeding species over time
  • to assess the long term trends of breeding species in our area

This survey began in 1991 and is one of the longest running local surveys of breeding birds in the country.

The survey requires observers to make 3 visits over the space of 3 months to a randomly allocated 1km square and record the breeding evidence of all species observed along with their number.

To participate in this survey, please contact the BOS Bird Recorder: Contacts.

For further details on the survey see Summer Random Square Survey.
