I have captured these photographs for La Vanguardia’s Readers’ Photos of these geese that have parked in the Sau reservoir. The truth is that I didn’t know them, they are very big and colorful.
These birds have become an added attraction in a reservoir that has been the center of attention throughout the drought period, when its landscape has been gradually changing, with new vegetation around it.
These days the presence of the Nile goose or Egyptian goose (Alopochen aegyptiaca) is surprising, a species of anseriform bird from the Anatidae family native to Africa, the only one of its genus currently not extinct. What is he doing in the Sau swamp?…
Well, it turns out that this bird has great colonizing potential and constitutes a serious threat to native species, habitats or ecosystems, according to the Spanish Catalog of Invasive Exotic Species.
So much so that, in Spain, its introduction into the natural environment, its possession, its transport, its trafficking and its trade are prohibited, so it is to be assumed that these specimens of Nile goose that have settled in the swamp of Sau are the fruit of their own migration.
