Species Spotlight: Chiloé Wigeon
Alex Levitskiy
During these cold winter months I have selected to discuss a tropical duck species: the Chiloé Wigeon (Mareca sibilatrix). These ducks are native to South America, but they can be kept in northern climates as long as they are provided with some sort of winter protection. The Chiloé Wigeon is one of three wigeons, and breeds primarily in Argentina, Uruguay, and Chile. Their population is fairly large in the wild, so the Chiloé Wigeon is classified at Least Concern. The classification of Least Concern denotes that the species has a relatively low risk of extinction. This species of duck is also common in captivity. A distinguishing feature of this wigeon is their whistling sound, which is a pleasure to hear.
The sexual dimorphism is subtle between the sexes of the Chiloé Wigeon. The male is slightly larger with more iridescence on his head, and his plumage is brighter than that of the female. As with other South American ducks, the Chiloé Wigeon does not have an eclipse plumage. An eclipse plumage is the nonbreeding plumage of male ducks after they molt shortly after breeding season, making them appear similar to the hens of the species. As a result, the Chiloé Wigeon keeps its color all year round making it a nice choice to brighten up the summer months, when other drakes are in nonbreeding plumage.
