Pond Boss Forums INTRO Questions & Observations First ducks on the new pond

I have ducks that sound similar to that on my pond in Missouri too Adam Klaus. I don't know what they are, but the wing beats sound like they are whistling. I like watching them too. I have had a few before this year, but seem to have many more this year and they have been around longer I think.
Best of luck with your new pond.
