Image Two: Muscovy Duck

The duck in the video above recently began visiting the duck pond at The Reserve at Forest Hills at the corner of Darlington Ave and Covil here in Wilmington NC February 11th 2018. This particular pond is a home to many waterfowl that come and go. Spotted in this community include; Canadian geese, Greater white geese, Mallard ducks, Blue heron, Snowy egrets, Hooded merganser, Little blue heron, and the occasional Sandpiper.

Cairina Moschata more commonly known as the Muscovy Duck originate in South America but can be found naturally in the wild in Southern Texas since the 1980s. The Muscovy Duck is widespread throughout the world in domesticated settings for their meat and eggs. They resemble a goose in size and the male can reach up to 7 kg. Small feral populations throughout the United States but particularly in Florida are reported, and are considered to be invasive by the Florida Fish and Wildlife conservation Commission. An invasive species is a species that is not native to an area, and is more popularly defined as a nonnative species that is harmful to the native wildlife or environment. Although Muscovy ducks are not that different from your typical mallard, and have even been bred with mallards to increase mallard size . However they can have a very negative impact on bird species that they share their wetland ecosystems. Not only do they often displace native species but they also are known to carry a disease called duck viral enteritis. This disease is not normally encountered by native birds and can cause devastation to their communities. Consider the competitive exclusion principle, where Muscovy and other wetland birds compete for the same resource. Unfortunately Muscovy are well adapted to their wetland environments and as an invasive species often displace or exclude the native species. We could predict a inter-specific competition to be scramble exploitative, where both species have access but Muscovy are better adapted to use more of the resource, pushing out other species out . The result in Southern Florida has been many debates on the best method to rid themselves of Muscovy ducks, and demand for laws to address humane ways to do so. Considering the effect the Muscovy duck can have on local bird populations finding an appropriate way to contain them as domestic species and reduce their feral populations.
