The Muscovy duck is a large duck native to the Americas, from the Rio Grande Valley of Texas and Mexico south to Argentina and Uruguay. Males weigh up to 15 lbs. Females are noticeably smaller. Muscovy ducks hiss, instead of quacking. They also wag their tail similiar to a dog.
 
They are thin-skinned, low in fat, and have deep red, mildly gamey meat which is sometimes compared to roast beef for its flavor, and veal for its tenderness.
