Summary:Altogether 23 species of waterbirds were registered during the middle of January in 2009–2016 on Váh River in Liptov region (northern Slovakia). Neither total number of species nor number of birds correlated with the temperature (free or frozen water surface of a large water dam Liptovská Mara). However, the proportion of diving birds registered on the river was positively associated with the ice extent in the water dam. The most numerous bird species was Mallard (Anas platyrhynchos) representing more than 80% of all wintering waterbirds of region and registered on all parts of the river and during all seasons. Constant and frequent species were also Water Dipper (Cinclus cinclus), Grey Heron (Ardea cinerea) and Kingfisher (Alcedo atthis).
