First record of parasitism of Black-headed Duck with the host. (See Brood Parasitism). The Black-headed Duck is the only obligate parasite. It parasitizes many aquatic species and in this case the host is a Rosy-bille Pochard. Since July there have been frequent records of thd Black-headed Duck, which makes us presume there may appear more cases. So, when you spot any water bird family, check all chicks are the same. There may also be facultative parasitism.
According to the literature these ducklings leave their host parents very soon. It would be interesting to follow it and count its story. This photo was taken in the Duck Pond from the burnt viewpoint. Send any information you can collect.

Shorebirds blend very well in the ground so it is very difficult to find them. In many cases we detect them when they are driven away by neighbours and fly away as is the case of this Great Kiskadee in the photo below.
