Could be dog pee. Don't worry about it.

Re: rusty or yellowish on stucco
Thank you, Possible. My thought is the poor stucco finish & high humidity around vent, which caused rusty spots from metal mesh or vent screen, is it possible?

Re: rusty or yellowish on stucco
Around here it'd most likely be due to iron from well water that is sprayed onto the siding from a yard sprinkler.
