I was eating lunch on the patio at Panera today (March 1) in Colonial Heights, Virginia, and a bird was in a tree close by. It sounded so happy, I decided to catch 30 seconds of it on my phone. You might have to increase the volume a bit, because there's some traffic noise in the background. I never saw the bird, so I don't know what type it was. Can anybody identify it by the song? 

Song bird 3.1.12

Sounds from Saturday afternoon

Sounds from Monday afternoon

I listen mostly to ambient, electronica, chill, neo-classical.
