Anas platyrhynchos recorded 8404 individuals (35.47% of the registered total – 23696 individuals). From the ecological point of view, Anas platyrhynchos, Aythya ferina and Larus ridibundus (6.52%) were eudominant species, Anas crecca, Fulica atra and Larus canus (6.52%) were dominant species, Anser albifrons and Larus cachinnans (4.34%) were subdominant species and Phalacrocorax carbo and Aythya fuligula (4.34%) were recedent species.
