When I was a kid growing up on the Gulf Coast, I remember what the atmosphere and the weather would be like as a hurricane approached. Cloud cover would envelop the sky, and a strange quiet would settle on us. I supposed the birds and beasts all knew what was coming, and they'd already made their way to shelter in the face of the approaching storm. I never got to experience a direct hit, complete with eye of calm, that I can recall, but those hours just before the storm hit were as calm and quiet as a tomb--and it was like being in a weird dream. The sky was a weird color, and everything glowed in this surreal way, and there were no birds singing. Freaky.
I guess that's what a life without birds would be--like a tomb. I can't imagine going outside in the backyard now and not hearing my birdy friends calling and singing to one another. Sometimes the noise of all the birds is almost deafening; you can feel your eardrums vibrating with the overwhelming high-pitched sounds.
Life without birds would, in a word, suck. Let's hope we never have to live such a life.
