The Mergus octosetaceus (Brazilian Merganser) is very demanding in choosing its habitat. It depends on clean and transparent waters, since they feed only on fish, they need to have a clear view underwater to be able to dive and hunt. That’s why the name, which means Diving Duck in Portuguese. They enjoy rivers with rapids, vegetation on the banks and are extremely affected by the degradation of the waters. For this reason, they are considered BIO-INDICATORS, where there is the presence of the species, indicates that the ecosystem is in proper balance.

To save the species from extinction, the Chico Mendes Institute for Biodiversity Conservation (ICMBio), a Brazilian federal agency, linked to the Ministry of the Environment (MMA), which manages endangered species, created the National Action Plan for Conservation of the Mergulhar octosetaceus (Brazilian Merganser), in order to save the species from extinction, where several private and public entities perform actions in several areas in order to help the species.

Due to the great importance of the conservation of this species, the Mergus octosetaceus (Brazilian Merganser) received the title of Ambassador of the Waters of Brazil, a title more than deserved at the 8th World Water Forum in March 2018 in Brasilia. Because when we talk about the conservation of the duck we are talking about the conservation of all biodiversity, the conservation of the main sources of rivers that supplies our homes every day with drinkable water!
