Summary: | Since the first occurrence of the Egyptian Goose (Alopochen aegyptiaca) in Slovakia in 1993, a significant increase in its abundance has been recorded, until end of 2019 as many as 103 observation records were found, from year 2007 several new records appear almost annually. The first breeding was confirmed in 2014, next two cases in 2015 and 2017. In 2019, the fourth breeding was documented in the city of Bratislava – at the Kuchajda lake, with recorded agonistic behaviour against Mallards (Anas platyrhynchos). Further spread of the Egyptian Goose, considered an invasive species in the EU, is envisaged also in Slovakia. Possible negative influence of the species on autochthonous avifauna is discussed. |
