I agree with Dr Todd.. go with the Ring Teal! I have both Mandarins and Ring Teal, along with several other species and the Ring teal are one of my favorites.. The drakes never lose their color and they make noises that to me and my dad sound like cats. Plus they are small to. This was our first year having birds to breed and the Ring teal and the Manadarins did the best. We had good luck with the Wood ducks to but you need a permit if you are every going to sell and trade them.
