At different locations in the Netherlands Jackdaws are provided with yellow color rings with an inscription starting with the letter E. The purpose of adding these rings is to gain more insight into the survival and spread of Jackdaws. The birds are mainly ringed in different places within built-up areas. With this research we hope to find out whether the birds that live in urban areas also use the countryside or whether these are different populations. Every observation, especially outside our own research area, is therefore of great importance.
