Photo 17: Second winter LBBG, October 22 2001, Westkapelle, the Netherlands.

An example of what seems to be a random moult strategy. This sequence can be found in LBBG's pretty often: note e.g. the median coverts. The inner 4 medians have been replaced by new feathers. Number 5 and 6 are still old and the outer wing-coverts are replaced in a descendant order. The same sequence holds for the greater coverts, while the lesser covert moult often lacks a true strategy, though starts with the inner lower lesser coverts.

It's hard to pin down the exact origin of this bird, but some Icelandic LBBG's may resemble this plumage.
