The only way to tell these two drakes apart is this beautifully curled tail feather. They travel in a trio with the female and are seldom seen alone but I was able get this while the hen was on the nest at sunrise this morning. I love the first rays of sunlight catching his back and beak.
@jan11 They are very racist! The rest of the ducks are mascovy and these Indian Runners won't mix with them and forage together. The curly tailed one is actually the boss but as long as the other one keeps his place all is peaceful.
