Lesser Black-backed Gull (graellsii & intermedius)

(last update: 22-2-2011)

LBBG 3cyAugust 23 2000, Le Portel, NW France.

This bird has finished the complete moult of under-parts, upper-parts, tail and wing-coverts. P8-10 are still growing. Note that the upper tertial is missing, which may imply the bird has commenced the partial moult of the coverts and upper tertials. During late summer, the initially adult-like colouration of the bare parts changes and  becomes immature-like again.
