Nice to see this new high-quality publication by the Office National de la Chasse et de la Faune Sauvage (French National Office of Hunting and Wildlife) in its English version on the Duck Specialist Group website.
I had only a quick look through it, and it looks great. Nice intro with generic ageing and sexing features, and then detailed species accounts for most common European duck species.
Very useful reference for ringers and for field birders too.
The guide can be downloaded here.
