Abstract

Similarly to the 2005 (Kovács, 2008a) and 2006 (Kovács, 2008b) bird censuses, the South-Balaton Nature Conservation Group (BirdLife Hungary) organized a synchronous waterbird survey at 51 plots around Lake Balaton and other wetlands connected to its southern shore on the 10th of November 2007 (Table 1, Map 1). On Lake Balaton 21 waterbird species (belonging to 8 families), while on fishponds and other wetland habitats (7 plots) 37 species were recorded (Table 2, Map 2). 83% of the individuals (18 400 birds) were counted on Lake Balaton, while the number of individuals recorded in the other wetland habitats was somewhat less than 4 000 birds. The biggest flock of birds (2 500 individuals) was observed in Nagyberek (Fehérvíz Nature Conservation Area). The most abundant bird species was the Eurasian Coot (Fulica atra) (6 800 individuals) (Figure 1). The number of individuals counted for the Mallard (Anas platyrhynchos) was also high and this species was the most constant waterbird (Figure 3). Figures 1 and 2 show the remaining dominant (D >5%), accessory (D 1-5%) and accidental (D 0,1-1%) species. The following observers were participated in the count: Zsolt Bende, Ádám Faragó, Szabolcs Gál, Réka Jambrich, Balázs Kárász, Gyula Kovács, Csaba László, Sándor Mogyorósi, ádám Nagy, Előd Szász, Ádám Tamás, Béla Vincze Jr. Special thanks for their help!
