Does anyone have the iBird app with the mallard duck calls? I was at the lake and played the flirty female and female in flight call. All the males perked right up and listened. Some even came up to me. When I played the male quack-whistle, they got agitated with each other. As soon as I stopped playing the female sounds, all the males started quacking up a storm! I have wood duck calls, too, but I didn't see any wood ducks around. Anyone else do that with their ducks?
