Status and distribution in Luxembourg

Distribution map of Alopochen aegyptiaca L. in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2020-01-27.

The first documented observation in Luxembourg was made by R. Gloden in late December 1984 in Bech-Kleinmacher (Municipality of Schengen) on the Moselle; the first successful breeding attempt took place in 2007 in the nature conservation area, Haff Réimech, near Remerschen (Bastian 2016: 7). Some 20 to 30 breeding couples can now be observed every year. Outside of the breeding season, the species can be seen in large numbers on rivers or stagnant waters (Lorgé & Melchior 2015). Today the species is widespread in the country. It occurs less often north of the Sure river (Bastian 2016: 13) although a small population of 3 individuals were observed on the Our lake during summer and autumn 2016 (Ries 2016, own observation). A recent survey estimates the actual breeding population as a total of 39 breeding couples (Bastian 2016: 13).

The Egyptian goose is found in a diversity of wetlands, usually supplied with a belt of trees or shrubs. The species seems to be in strong expansion, Belgium is one example. During the nesting period, it develops aggressive behaviour leading to nest usurpation and decrease of offspring number in several bird species (see also Konter 2015), namely herons and raptors. Post-breeding flocks are responsible for overgrazing and for the alteration of banks and quality of water bodies (Source:
