Moreover, if there are sparrows or some birds with swallows downstairs, potential parents are also very energetic, because this energetic house or family can attract many animals.
So I suggest you don't drive these sparrows away. You should let sparrows nest in your home, which will increase your stress and wealth, and also add some vitality to eating.
And now the sparrow belongs to the national second-class protected animal, you can't hurt it, but if you hurt the sparrow, you are breaking the law and you have to bear the corresponding legal responsibilities.
