For the third year in a row we have a mother duck sitting on her nest in a plant box on our roof terrace. It seems to me to be a strange place to breed ducks as it is 5 stories high. Each time the ducklings hatch they are in danger of falling off the roof.
But as I say this is the third year that she has come back. She probably thinks that it is a safe haven because there is always a crew of humans anxiously waiting for the ducklings to hatch. When they do hatch we dutifully ring Animal Welfare (dierenambulance). They come and catch mother and the babies and then take them all to a park. So Mother Duck seems to think that she is well looked after because she keeps coming back.
The only problem is that Father Duck never knows where the family is taken to (apparently ducks mate for life). After all, they go by ambulance and he has to fly. So after the family has left he returns each morning and evening and honks mournfully for them. But somehow he manages to successfully hook up with her by the time the next Spring rolls around.
