I live in a small block of flats by the sea and the residents have sought the advice of a sea gull removing service who recommend the removal of these birds nests in every season. I am not happy with this, least because I am sure it is against the law but that it is not the right thing to do. Is there another way these birds can be less inclined to want to nest there than to remove their nests?
After they have bred you can try to deter them from nesting in the same place again next time

Gull nests started appearing in my neigbourhood during lockdown, when people were feeding them with their leftovers. Aside from the noise and mess, they were deterring all the smaller birds. The trick is to stop the nesting early, when they start hanging around in March and April, encouraging them to go elsewhere. Two wanders around the area a day, early morning and afternoon, armed with a catapult and snaps has been totally effective. No great proficiency necessary. The bang in their general area is sufficient.
