After termination of the national project "Jaar van de spreeuw" (Year of the Startling) in 2014 VRS het Gooi and VRS de Haar joined efforts to continue the colour ringing research on this species. The birds are ringed at various locations in Utrecht en het Gooi, The Netherlands. Both nestlings as well as flying hatch year birds and adults are included in this project. Using colour rings we hope to increase the number of reports of these bird, thereby allowing us to learn more about migration, dispersal and survival.

Besides numbers and letters 4 special signs were also used: ":" (colum), "*" (asterisk), "#" (hachtag) and "+" (plus).
