Ad Herring gull (L. argentatus). 26-09-09

After beeing out at Holidays and some days in the Tarragona festivals, today I've been back to the harbour. Many Lesser black-backed gulls, decreasing numbers of Yellow-legged gulls and the first Herring gull. The last looks the same individual observed in the area last 8 winters. According to other years phenology, the individual should be in the area for about one month.

Ad Herring gull (L. argentatus). 26-09-09. Note the differences between Herring and Yellow-legged gull.
Out of the leg colour, note the differences in size and structure, back grey tone, iris colour and primary moult stage.
