Demography and Populations


We have no information about survival and dispersal of the Brazilian Merganser. Filling this in our knowledge is fundamental to establishing effective conservation strategies for this species (see Priorities for Future Research).

The largest currently known population is in Serra da Canastra region. At least 50 territories were mapped by Terra Brasilis Institute (unpublished data) in that region. Significant populations seem to occur in other parts of Brazil, as for example, in Jalapão State Park region, where researches on this species are in initial phase. Further studies will allow a better estimate of the populations size.
