Good day, Tom, nice to visit with you here.
Yes, I love those ducks. They have been good to me, and good for me. A friend once told me he did not see how anyone could stay depressed around this flock.
You are absolutely right about the volumes that could be written on communication between species. It was Duckyfromoz and a few others here, years ago, who advised me on some specifics, though I already knew a few things just based on my experience with animals. Duckyfromoz told me about not approaching from above, and making gentle noises before coming into sight. I read somewhere else that cornering a duck is terrifying to it.
Take care.
