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 2019 őszén. Waterbird census was carried out on 54 survey plots around Lake Balaton and its surrounding wetlands on 17th November 2019, 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 44 waterbird species from 9 orders and 11 families were observed (Table 1.). The highest number (>2500 ind.) was counted at Balatonboglár, the highest species richness was found at Fonyód and at Balatonszemes. We counted more than 1000 individuals in further 4 plots (Table 2., Map 1.), while species richness was exceeded 10 in 15 survey plots (Map 2.). On the fishponds and marshes, the dominant (D>5%) species were the Greater White-fronted Goose, the Black-headed Gull, the Greater White-fronted Goose, the Mallard, and the Northern Lapwing. On Lake Balaton the Eurasian Coot, the Mallard, the Greylag Goose, the Common Pochard, and the Black-headed Gull. Interesting faunistic result was the occurrence of the the Black-throated Loon (2-3-2-1-1 ind. at Szántód, Balatonföldvár, Balatonszabadi, Balatonaliga, Alsóörs), the Common Scoter (3-1 ind. at Balatonszabadi, Balatonakarattya), the Red-necked Grebe (2-1 ind. at Balatonfűzfő kikötő-Tobruk, Balatonakali), the Red-breasted Merganser (1-1 ind. at Bélatelep, Balatonaliga), the Horned Grebe (1-1 ind. at Szántód, Balatonszabadi), the Red-throated Loon (1 ind. at Fonyód), the Red Phalarope (1 ind. at Balatonszabadi) and the European Herring Gull (1 ind. at Alsóörs).
