Abstract

Az elmúlt évekhez hasonlóan (KOVÁCS, 2008a, 2008b, 2008c, 2013a, 2013b, 2013c, 2013d, 2015; KOVÁCS & HAJDU, 2015a, 2015b; KOVÁCS & BRUCKNER 2022a, 2022b, 2022c) az MME Dél-Balatoni Helyi Csoportjának szervezésében vízimadár-felmérést végeztünk a teljes Balatonon és a környező vizesélőhelyeken 2020 év elején. Waterbird census was carried out on 58 survey plots around Lake Balaton and its surrounding wetlands on 19th January 2020, like in previous years (KOVÁCS, 2008a, 2008b, 2008c, 2013a, 2013b, 2013c, 2013d, 2015; KOVÁCS & HAJDU, 2015a, 2015b; KOVÁCS & BRUCKNER 2022a, 2022b, 2022c) by BirdLife Hungary South-Balaton Local Group. A total of 38 waterbird species from 8 orders and 8 families were observed (Table 1.). The highest number (>3300 ind.) was counted at Balatonszemes, the highest species richness was found at Balatonkenese. We counted more than 1000 individuals in further 8 plots (Table 2., Map 1.), while species richness was exceeded 10 in 23 survey plots (Map 2.). On the fishponds and marshes, the dominant (D>5%) species were the Black-headed Gull, the Greylag Goose, the Greater White-fronted Goose, the Mallard, the Yellow-legged/Caspian Gull and the Eurasian Teal. On Lake Balaton the Eurasian Coot, the Mallard, the Common Pochard, the Common Goldeneye, the Tufted Duck, and the Black-headed Gull. Interesting faunistic result was the occurrence of the Greater Scaup (7 ind.), the Long-tailed Duck (1 ind.), the Velvet Scoter (5 ind. at Bélatelep); the Red-throated Loon (2-2-1 ind. at Balatonkenese, Balatonfűzfő, Balatonalmádi); the Black-throated Loon (1 ind. at Balatonkenese, Balatonkenese-Balatonfűzfő); the Red-necked Grebe (1-1 ind. at Balatonkenese, Káptalanfüred) and the Black-necked Grebe (2-1-1-1 at Fonyód, Balatonboglár, Balatonlelle, Balatonszepezd).
