Hi Rui,

It still is a 1cy LBBG, albeit with largely replaced wing-covert panel. This sometimes happens, already as early as within the colony. We did some research a few years ago to explain this phenomenon; have a look at the 1cy May, June, July sections of ORG:

The 1cy birds even made it to get into a real "movie". ;-)
