Arjen Dwarshuis shows us the Oostvaardersplassen. He hears many species, and I see some of them too. The nicest for me were Pontic gulls, a species that look very much like herring gulls to me. Not for Arjen, he was able to explain to me that I compared it to herring gulls based on the light underside and the relatively flat head.
