The Muscovy Duck (Cairina moschata)

Description:

This duck has a red eye patch on a white or black head and the body is mostly black with what looks like random white spots. They seem to swim in groups of three or four. They were "picking" at each other when they get too close to each other. They would also flap their wings at each other.

Habitat:

The Muscovy Duck (Cairina moschata) is a large duck which is native to Mexico and Central and South America. A small wild population reaches into the United States in the lower Rio Grande Valley of Texas. There also are feral breeding populations in North America in and around public parks in nearly every state of the USA and in the Canadian provinces; feral populations also exist in Europe. Although the Muscovy Duck is a tropical bird, it adapts to icy and snowy conditions down to –12°C (10°F) and below without ill effects.[2][3] In general, "Barbary Duck" is the usual term for C. moschata in a culinary context.
