Bufflehead

It is called amanacoche because of its white feathers placed on both sides of its head. It is the size of the common teal. The crown of its head is ashen; its neck is also ashen. Its breast is white; its back black: its tail black with two white [feathers], one on one side, one on the other. Its wing-bends have white placed on both surfaces; its wings half white, half black, the tips black. Its legs are black. It also migrates; it does not rear its young here. Many come. They are edible.
