SOURCE: Black smoke coming from tail pipe when

You say when starting, I presume you mean when the engine is cold? Black smoke is usually a sign that the engine is burning too much fuel but when it's cold this quite normal as the choke richens the fuel/air mixture to start the cold engine.
If it's still smokey when warm then it could be numerous things from a dirty air filter to a faulty cold air sensor giving the ecu a false reading. I would have the car serviced & if no improvement then leave it into a garage with diagnostics & they should be able to where the fault lies.

its due to the dew or the wet condition prevailing in your area, idle the car for sometime, then you can notice the white smoke disappearing.. :)
