Crows in Brussels

Today I got the chance to spend some time in a city parc in Brussels, resulting in the reading of 10 c-ringed Carrion crows. These birds are all ringed somewhere in Brussels (I am waiting for the details), with white or yellow rings with 2 codes. No pictures today (I didn't take my camera since I didn't know how easy it would be te read rings), that's something for the next time there...
