My bird neighbors love easy listening music.

I live in a wooded area with a very vocal bird population. I swear that on days when I go out and relax and put on my outdoor speakers, the once quiet birds around my yard suddenly perk to life in song. On many occasions I noticed this behavior. After much testing, I find that they prefer 70s easy listening yacht rock as well as any 45 minute rendition of Dark Star from the 83 European tour. Michael McDonald tracks usually stir up quite a bit of conversation.
