We have two duck ponds in our estate and the ducks are protected.
When Mum and Dad wander around the estate with their ducklings everyone gives them right of way. They know how protected they are:
When I first moved here with my cat Roxanne she watched mum and ducklings with dad on the end, wandering past my house.
She was about to pounce when father duck came charging over, flapping his wings and quacking as he attacked her. She has never challenged the ducks since. In fact she completely ignores them now!
I wish she would at least chase them away as they leave a lot of deposits on my driveway.
Some “quacking” information for you.
