Lesser Black-backed Gull intermedius J976Z 2CY, May 16 2017, Leixões harbour, Matosinhos, Portugal. Picture: José Marques.Please visit José's FLICKR PHOTO STREAM and also José Blog "Seabirds Portugal". OBSERVATION REPORT All visible coverts were replaced in the post-juvenile moult, last winter, the MC row now already bleached. All rectrices and primaries (at least P5-P9) replaced in winter as well. This is what can be expected for fuscus fuscus, but in general the pattern on coverts and posture point to intermedius. New 3rd gen scaps growing in, rather ashy grey, not blackish. |
