CR-BIRDING SUBMIT is a relatively new initiative by Sovon, Vogeltrekstation and Dirk Raes to collect sightings of color ringed birds in a simple way. Readers can add and manage observations of color ringed birds of affiliated projects via the website. After input, they also receive the life history (where and when ringed and where and when observed thereafter). Affiliated project coordinators (person who started and managed a specific project) use the observations entered for their research. The number of participating color ring projects is growing rapidly; currently 22 projects are participating.
