We had to have barriers set up to stop pigeons nesting under our PV panels. Warning that pigeon chicks have mites. The mites fall/crawl through the roofing tiles get into loft. Seeking food they then find a way through light fittings and before you know they will be in your bed linen & mattress. The guy who fitted our barriers had further stories of damage pigeons can do.
