Gang-gang Plumage

["John Leonard" <>]

I've noticed that a lot of the males around here which are in fully
adult plumage, ie complete red head, no orange on breast, have a light
yellow wash over some of the primaries.

Is this a feature of the plumage of all male GGs, or is it a feature
that disappears with further moults and can be used to identify
younger birds?

ps I've just been looking at some of my photos and it seems that
females and immature males have yellowish-white margins to the
feathers on the mantle and on the primaries. In adult males these
margins are whiter, the yellow wash is separate feature across the
main body of the primary and doesn't seem to reach to the mantle.
