In the country there no honking horns(汽车喇叭声)，no diesel trucks, no pollution—just the sounds of wind rustling the tree leaves and red squirrels (松鼠)chattering in the distant oaks and cool creek water rushing down its endless course.

请问老师，是三个并列动名词短语作存在句的真正主语，还是现在分词作定语分别修饰wind, red squirrels, 以及cool creek water?

谢谢老师。
