opmerkingen 6 Octo­ber, Westkapelle, Veere, Zeeland, fourth calendar-year, wearing colour-ring, photographed (I Meulmeester; Dutch Birding 31: 396, plate 54, 2009). The fourth calendar-year (with black ring with white inscription J781 on its left leg) had been ringed as a pullus in Somna, Nordland, Norway, on 27 July 2006. Only birds ringed at a nest in a 'pure' Baltic Gull colony are currently considered acceptable but this may change when the CDNA decides to follow the recommendations by Altenburg et al (2011), who argue that unringed second calendar-year individuals meeting a strict set of criteria based on plumage and moult are safely identifiable in the field.
