Habitat Comparison
Mauritius Duck
Historically restricted to the Mascarene Islands (Mauritius and Réunion) in the Indian Ocean. Now extinct. Presumably inhabited freshwater wetlands and coastal areas before human colonization.
Stockente
Nearly any wetland habitat including lakes, rivers, ponds, marshes, estuaries, and urban park ponds.

Die Stockente ist die Stammform der meisten Hausentenrassen und die häufigste und am weitesten verbreitete Schwimmente der Welt. Erpel zeigen aufwendige Balzrituale, darunter Kopfnicken und pfeifend-grunzende Rufe. Stockenten sind äußerst anpassungsfähig und gedeihen sowohl in der Wildnis als auch in städtischen Lebensräumen.
