V11, Maasvlakte, the Netherlands, April 14 1999. Photo by Pim Wolf.
An adult bird ringed left white V11. In this case the white ring turned slightly orangey-white. The code V11 has a vertical T as well and was used in the early years of the ringing project (early 1990's). Note the dark diffuse bill-band and the relatively small white tips on the outer primaries.
