I really thought that I was just imagining things. But YES! My Saxony duck, Cinnamon whistles at me. It's not a sexy whistle, but more of a beaconing whistle. As if to say, "Come back, don't go!" He did it once. He did it twice... thrice! And now he's doing it all the time. Every time I go to leave Cinnamon calls after me with a distinct whistle! I had no idea!
Does anyone else's duck whistle? I didn't know ducks did this.
My male black bibbed/snowy call duck cross will whistle when he does his little mating dance, where he arches his back and tries to impress the ladies, but that's the only time I've hear a true whistle.
