Abstrakt | In the waterfowl census carried out in Slovenia on January 15th and 16th 2000 (IWC), 221 observers took part. On the basis of 489 reports, 47,172 aquatic birds were registered in the seven separate count areas. 55 different species were established (Table 1). All water birds were counted. Most important in terms of the birds' numbers were the count areas oF the Drava river, the Slovene Littoral, and the Upper Sava river. The most abundant species during the census was the Mallard Anas platyrhynchos, followed by the Common Coot Fulica atra, Black-headed Gull Larus ridibundus, Great Cormorant Phalacrocorax carbo, Yellow-legged Gull Larus cachinnans, Common Gull L. canus, Tufted Duck Aythya fuliguld, Little Grebe Tachybaptus ruficollis and Common Teal Anas crecca. Only standing waters in the interior of the country were more or less frozen over, while in the Littoral and in the Primorska region there was no ice. Partially frozen over were also the large river reservoirs on the Drava and Sava rivers. | |
Izvleček | Štetja vodnih ptic med 15. in 16.1 2000 (IWC) se je v Sloveniji udeležilo 221 popisovalcev. Na osnovi 489 poročil je bilo na sedmih števnih območij v državi preštetih 47.172 vodnih ptic. Ugotovljenih je bilo 55 različnih vrst (tabela 1). Štete so bile vse vrste vodnih ptic. Kvantitativno so bile za vodne ptice najpomembnejša števna območja Drave, Obale in zgornje Save. Najštevilnejše vrste med štetjem so bile mlakarica Anas platyrhynchos, liska Fulica atra, rečni galeb Larus ridibundus, kormoran Phalacrocorax carbo, tumenonogi Larus cachinnans in sivi galeb L. canus, čopasta črnica Aythya fuligula, mali ponirek Tachybaptus ruficollis in kreheljc Anas crecca. Med štetjem so bile stoječe vode v notranjosti države pretežno zaledenele, na Obali in Primorskem pa ne. Delno zaledenele so bile tudi velike rečne pretočne akumulacije na Dravi in Savi. | |
