V letu 2011 smo v obdobju od 26. 6. 2011 do 14. 8. 2011 opravljali popise izbranih vrst vodnih ptic na Račkih ribnikih v Krajinskem parku Rački ribniki % Požeg (SV Slovenija) na Velikem ribniku, Gajiču, Malem ribniku ter na treh stranskih bazenih. Popis smo opravljali z namenom, da ugotovimo izbiro habitatov izbranih vrst vodnih ptic, številčnost vrst ter število gnezd v času opazovanja. Popisovali smo 9 vrst vodnih ptičev in sicer: labod grbec Cygnus olor, mlakarica Anas platyrhynchos, sivka Aythya ferina, kostanjevka Aytya nyroca, čopasta črnica Aythya fuligula, mali ponirek Tachybaptus ruficollis, čopasti ponirek Podiceps cristatus, zelenonoga tukalica Gallinula chloropus ter liska Fulica atra. Območje raziskave smo razdelili na pet habitatov: rogoz, plavajoče rastline, mešano (plavajoče rastline in rogoz), odprto ter obrežje. Popis smo izvedli šestnajstkrat. Popisovali smo ob različnih delih dneva. Dan smo razdelili na štiri dele. V času od 8.00 do 11.00 (zjutraj) smo popis izvedli dvakrat, od 11.00 do 14.00 (opoldan) šestkrat, od 14.00 do 17.00 (popoldan) petkrat ter od 17.00 do 20.00 (zvečer) trikrat. Ribnike in bazene smo opazovali s kopnega, s ceste, ki poteka med ribniki ter z opazovalnice, ki se nahaja na južni strani ribnika Gajič. Bazene smo pregledali v celoti. Najštevilčnejša vrsta je bila liska, najmanj smo prešteli osebkov laboda grbca. Vse osebke smo opazili v habitatu plavajoče rastline in odprto. Največ osebkov smo popisali v habitatu odprto, najmanj pa v habitatu rogoz. Opazili smo 6 gnezd, štiri so pripadala čopastemu ponirku.

Sekundarni naslov: Habitat selection of selected waterbirds species at Rački ribniki
Sekundarni povzetek: In 2011, a census of selected water birds was performed between 26. 6. 2011 and 14. 8. 2011 at Rače fishponds in the Landscape park Rački ribniki % Požeg (north-eastern Slovenia), at Veliki ribnik, Gajič, Mali ribnik and the three smaller water basins. The census was performed with the aim to determine how the chosen water birds select their habitat, to evaluate the species` population, and to establish the number of nests during the period of observations. 9 different species of water birds were selected for the research: Mute Swan Cygnus olor, Mallard Anas platyrhynchos, (Common) Pochard Aythya ferina, Ferruginous Duck Aythya nyroca, Tufted Duck Aythya fuligula, Little Grebe Tachybaptus ruficollis, Great Crested Grebe Podiceps cristatus, (Common) Moorhen Gallinula chloropus and Coot Fulica atra. The study area was divided into five habitats: reed, floating plants, mixed habitats (floating plants and reed), open habitat and shores. The census was carried out sixteen times at different parts of the day. The day was divided into four parts. Between 8 and 11 a.m. (in the morning) the census was recorded two times, between 2 and 6 p.m. (in the afternoon) five times, between 5 and 10 p.m. (in the evening) three times. The ponds and basins were being watched from embankments, a road that runs between the ponds, and from an observatory tower located at the south side of pond Gajič. All basins were inspected thoroughly. Coot was the most abundant species, the least abundant species was Mute Swan. All species were recorded in the floating plants and open habitat. The highest number of individuals were counted on open water and the least were observed in reeds. Six nests were found; four belonged to the Great Crested Grebe.
