I always chuckle at birdsong, and how pretty it is. Most of it evolved to be some form of "GO AWAY" or "COME HAVE SEX PLEASE" that was loud and distinct enough to be heard over great distances and over the other noises in nature.

So, listening to sweet birdsong first thing in the morning is like going to a rowdy bar on a Saturday night and listening to the singles yell at each other over the music.

It genuinely never fails to make me chuckle when I'm on the porch listening to birds in the morning.
