Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 268 observers took part, 413 sections of the rivers and coastal sea with a total length of 1395.1 km and 226 other localities (178 standing waters and 48 streams) were surveyed. Altogether, 45,346 waterbirds of 62 species were counted. This is the lowest number of waterbirds recorded after the 1997 and 1998 censuses. The greatest numbers of waterbirds were counted in the Drava count area, i.e. 20,217 individuals (44.6% of all waterbirds in Slovenia). By far the most numerous species was Mallard Anas platyrhynchos (43.0% of all waterbirds), followed by Black-headed Gull Chroicocephalus ridibundus (10.1% of all waterbirds), Coot Fulica atra (7.9% of all waterbirds), Yellow-legged Gull Larus michahellis (6.0% of all waterbirds) and Cormorant Phalacrocorax carbo (4.6% of all waterbirds). The number of 1,000 counted individuals was also surpassed by Mute Swan Cygnus olor, Pochard Aythya ferina, Tufted Duck Ay. fuligula and Teal An. crecca. Among the rarer recorded species, the Black Stork Ciconia nigra (registered for the first time during the January Waterbird Censuses; only the second winter record in Slovenia), Cattle Egret Bubulcus ibis and Flamingo Phoenicopterus roseus (both registered only for the second time during the IWC) should be given a special mention.

Also, the total number of C and E category species/taxa was the highest to date, although still quite low with 70 individuals.
