Ducks families

At this time of year more and more ducks families are observed on lakes and rivers. Apart from Mallards, all kinds of wild ducks are monitored by the "monitoring of selected species" program for which the total number of brood is counted. In order to obtain an accurate synthesis at the end of the breeding season we need precise information. For these observations it is therefore important to mention specifically the number of families present and, for each family, the amount of chicks and their size has to be specified (remarks field). The following link gives indications on how to estimate the size of chicks relatively to the size of adults: Altersbestimmung bei Jungenten / Détermination de l'âge des canetons).

Thanks in advance for these precisions. They simplify the data analysis and the monitoring of rare species.
