    Yellow-legged Gull michahellis  2CY, October    22 2001, Westkapelle, the Netherlands. 
The common moult strategy in the coverts
  is shown by quite some birds depicted in this October Section: the
  innermost median and greater coverts are actively moulted, some lesser
  coverts are moulted randomly  and most of the outer and central
  median coverts are replaced.  
Here is an example of a different, random
  moult sequence in the greater coverts. The inner 7 greater coverts show
  bold contrasting patterns, #8-9 are grey-brown, moulted more recently, as
  were #11-14 and probably more outer greater coverts. The median coverts
  and tertials are all well-patterned and the fringes show extensive wear.
