A pigeon settled on my balcony. What should I do?

A pigeon is going to build a nest on my balcony. I tried to make it fly away but it comes back. I rent this flat and not sure if I'll stay there till winter. I mean if another person rents the flat he'll definitely get rid of it. In my country people have no respect for animals. Besides the hostess doesn't like that. Should I insist in chasing the bird from my balcony or let him stay there?
