The project is a Retrapping Adults for Survival project at the former island of Wieringen on the most northern point of Noord-Holland. Since 2000 several hundreds of birds are ringed. The survival rate differs per year, but is normally between 75 and 95% for adults. Most birds are seen in the breeding area, but there are also some interesting ring readings along the flyway between Netherlands and Africa.

All birds have a wihite ring on the tibia (with a letter followed bij 2 digits). Some birds also have a green flag on the other tibia.
