Lesser Black-backed Gull intermedius JAA08 2CY, October 06 2016, Matosinhos Beach, Matosinhos, Portugal. Picture: José Marques.Please visit José's FLICKR PHOTO STREAM and also José Blog "Seabirds Portugal". OBSERVATION REPORT Probably, due to an extensive post-juvenile moult in late winter (1st winter), the complete moult in summer followed a 'jumpy strategy' which now resulted in a more or less random mix of fresh dark grey and worn faded brown coverts. |
