1-5: © Visa Rauste, 28-05-06. Tampere, Finland.
A dark bird showing markings in the renewed wing coverts. The overall impression is that of a dark Caspian Gull. Gull. Note that due to a combination of exposure and extent of wing spread, plates 3 and 5 give a very different impression of how pale the inner webs to P-1-5 are.
