No Artist - Sound Effects - Birds Mp3

Cited on Wikipedia as the source of bird song on "Cirrus Minor" on Pink Floyd - Relics: "The opening birdsong is from a 1961 recording entitled "Dawn Chorus" and the single bird featured over the organ part is a nightingale also from 1961. Both featured on an HMV sound effects single (together with a recording of owls) but presumably the band just borrowed the originals from the EMI sound effects library as EMI owned HMV."
