cacophony: harsh or discordant sound

I always associate Spring with a cacophony of birds singing out from a great big tree, sprouting out buds of flowers and leaves, and pulsing like a giant heart. But where do you go to get that many birds. Nowadays I feel blessed to hear a thrush, or see a little robin. Mankind cut down the tree, broke the heart, and sent the birds flying. Then it shot them.
