The guide to the ageing and sexing of common European ducks, first published in 2014 by ONCFS, is now available in English and can be downloaded from the DSG website. The guide, translated by Matthieu Guillemain and Richard Hearn, covers the ten ducks most commonly observed, ringed and hunted in France (Red-crested Pochard, Common Pochard, Tufted Duck, Gadwall, Teal, Mallard, Pintail, Shoveler, Garganey and Wigeon).
The text is supplemented by tens of original photographs of wings and other specific plumage features for each species, with a concise text explaining which specific criteria to consider in each case.
The guide can be downloaded here (note the file is 75 MB) and can also be found in the Resources section of the DSG website.
Thanks to financial support from BASC, printed copies are available to purchase from ONCFS using this form.
Great document!
In case someone does not know, I think a good complement to this new publication is the ‘old’ book:
Suomen sorsalinnut (1983) by Aarno Salminen and drawings (black/white) by Dick Forsman.
It is a general guide for aging and sexing 34 Finnish waterbird species. Unfortunately, it is only in Finnish.
What is the proper citation for the English version of this guide?
The correct citation is:
Mouronval, J.B. 2016. Guide de détermination de l’âge et du sexe des canards. Office National de la Chasse et de la Faune Sauvage, Paris. English edition, translated by Guillemain, M. & R.D. Hearn, 2017.
