3cy Lesser Black-backed Gull from the Netherlands, ringed at Maasvlakte, Rotterdam on July 01 2001. Classical 3cy showing typical features for Dutch intergrade / graellsii LBBG:

  1. The basal half of the bill is yellowish while there is still much dark on the bill, often a complete bill-band;
  2. The iris is densely speckled, or, as in this individual, clouded;
  3. The lower tertials show obvious dark centres;
  4. The greater coverts show dense pale brown barring;
  5. The primary coverts have a brownish-whitish tip and have a brown-hued grey centre;
  6. The tips of the outer primaries are relatively small, hardly visible and there is a very small mirror on P10.
