When sounds hit nature what it produces seems like vibrations. A synthetic wave coming from both sides and crashes into one another and causes the wind to blow.

The bird in question is gainfully at odds with the sounds around it. The sounds/the word around it that generated everything. It's a wheel and the WORD is placed on it so when it is spun, it keeps repeating a statement consistently and coherent and with greater speed.
In this case the word is "pretty Bird" and the birds are flying within the harmony of the sound.
