Default Pigeon poo protection

I was looking well feeling, an old aerial a person had taken of their roof a

There was a bridge in America which collapsed to the detriment of the
motorists using it at the time, and the official explanation was that
the metal had been rotted over time by pigeon poo.

It does seem to be a recognised effect.

Maybe some parts of an aerial were more susceptible than others to such
damage, but all metal parts will eventually succumb to corrosion caused
by pigeons.
