Many thanks to everybody how provided us with their images! As you will understand, not everything could be used, but at least 18 ‘gaps’ are filled, so we are very happy with this result so far.
I have update the list in which the filled gaps are marked with ‘COVERED’, but as you will see, there are still quite a few open. So, if you have, or you know somebody how might have images that maybe can filled these final gaps, please let us know. Of course we know that these last 'gaps' are probably the most difficult plumage-types to photograph. So, all help until now is much appreciated!
