Cayuga ducks are a fantastic breed to look at - Often shimmering blues, purples and greens. 
Cayugas are a true black duck, not a dark brown. 

As the birds get older, they fade out to white through multiple molts, often taking on a dalmation appearance. Just as pretty!
 
Cayugas are terrible fliers. They're apt to stick around your property and not wonder off.
