Blackbird and Janis Joplin
Rock band was playing somewhere in the neighborhood. Suddenly a Common Blackbird with a nest in a nearby garden arrived and started to sing. First gently as he was shy but suddenly just before the band started to play Jimmy Hendrix and Janis Joplin the bird began to sing very loud a fabulous song (this following Audio Boo), something I have never heard it sing before, but this bird has been around my house for some years now.
