Confidence: I'm as sure as I can be.
Notes: This pair of ducks,female Mandarin and male Carolina were on my garden pond. They are escapees, living in the wild. I haven't seen these two breeds pair before, and I assume, even if it wasn't too late, that they cannot breed.
The pond was constructed in April, and given the drought conditions, has become a veritable watering hole ! On the negative side, visiting mallards have eaten 80 bunches of oxygenating plants ! That's frustrating.
