This duck is beetle-green-black in color. The bill is also black. Honestly, this is one of the most distinctive breeds of duck there is, and it looks really stunning. That's why it's always surprising that this bird is in danger of extinction.

It is worth noting that as the Cayugas age their coloration changes slightly over time. Some people have noticed that their ducks take on a slightly more orange coloration as they age. If you look at the duck in certain lighting conditions, it also has a slightly green hue.
