I love listening to birds go off at sunrise in spring. It is like they have been beat down by harsh winter weather and they celebrate the return of warmth and greenery. I live next to a college campus and it is inundated with large old growth trees and songbirds. When I walk outside to go to work I am hit by a deep field of cacophonous echoing happy bird sound that is unlike anything I have heard before. It is like something out of a vast swirling dreamscape where birds are sentient machines and their songs have a secret coded meaning.
