Ah, I love birdsongs. We have a lot of mockingbirds in the area, and they do such a good impression of a car alarm that sometimes you see people run out to their cars or look outside, looking for the idiot who can't shut off the alarm. Oops, no, it's just the birdies.
Now that we leave the windows open a lot, and since the sunrise is very early, we hear 'em all getting up and greeting the day. Sounds like a tropical rain forest half the time.
