For more than forty years, Sovon has been active in developing and expanding a monitoring network to account for all the wild bird species in the Netherlands. The dataset is based on the observations of more than 10,000 volunteers and trained field biologists.

Due to the expansive network of bird watchers as well as the close collaboration with various institutes and organizations we are in a position to report on yearly changes in population dynamics and distribution for most of the bird species present in the Netherlands. The results of the bird censuses which Sovon organise form the basis for the nature conservation and management and are currently being utilized for diverse applications.

Quality is a cornerstone in Sovon’s fieldwork.
