Music of Birds

I am grateful for bird song.  For many reasons.

1.  It doesn't change.  The Baltimore oriole, the wren, the white-throated sparrow, their warbling of 70 years ago is the same beautiful song today.  And I never tire of it.
2.  Bird song has no genres, no categories or sub-categories.
3.  No video.  Always live in concert.
4.  No batteries are required.
5.  It's free.
6.  No singing at night.
