This paper presents the results of the ornithological surveys performed on the reservoirs situated on the Some$ul Cald Valley during the years 1977-1998. Due to the fact that these reservoirs freeze only partially during winters they become a proper wintering site for water birds. A total of 21 species were recorded on the lakes, including some common species, like Anas platyrhynchos, as well as some species rare in Transylvania and also in Romania, like Phalacrocorax pygmaeus, Egretta alba, Aythya marila and Somateria mollissima. Few passage birds occur during spring and autumn.
