That poor girl and her family. We had a chat about this with our vet. We have pigeons who nest on our roof, and I donāt have a ladder tall enough or the expertise to know how to shoo them away (and I must admit, I rather like them). She laughed and said while pigeons are like rats and can be disease vectors, the more serious risk is waterfowl. I hope this holds true, because Iām not sure how avoid the little guys; theyāre everywhere here in the city, and they nest on the neighborsā roofs as well. Iāve never seen one sick thankfully; we even had one fledge in our yard.
