Annual counts

Counts are made annually at around 2,850 wetland sites of all habitats; estuaries and large stillwaters predominate. Some sites are large and split into separate count sectors.

Monthly counts

Monthly coordinated counts are made mostly by volunteers, principally from September to March, with fewer observations during the summer months.

Success and dedication

The success and growth of these count schemes accurately reflect the enthusiasm and dedication of the several thousands of volunteer ornithologists who participate. It is largely due to their efforts that waterbird monitoring in the UK is held in such international high regard.
