Seagulls do...for sure!
Pigeons do not defecate on the wing, but must be landed to defecate. Their legs grip the base of the tail during flight to increase streamlining, and means they cant defecate on the wing as other birds do, such as seagulls.
Any and all. It is a way of lightening the body for flight.
Birds don't know what a car is, they just need to defecate. Also, they often defecate as they fly so their poop falls just anywhere.
Of course they do.
