The WeBS Core Counts scheme is the principal scheme of The Wetland Bird Survey. Counts are made annually at around 2,850 wetland sites of all habitats; estuaries and large still waters predominate. Some sites are large and split into separate count sectors. Monthly coordinated counts are made mostly by volunteers, principally from September to March, with fewer observations during summer months. The success and growth of these count schemes accurately reflects 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.
