If it’s a hot, sunny day, as little as 10 minutes. The droppings can bake on the paint making it difficult to remove. Also heat might make the uric acid in bird dropping work faster. Certainly leaving the droppings on overnight isn’t going to help things.

A good coat of wax may help matters. If nothing else, the wax makes getting the crap off easier.

Agreed, but getting it on the bird’s ass could be a problem…
