Corbin, one of our 2 cockatiels, often whistles long tunes. Unfortunately, no one can tell what he’s whistling.
You can tell that he’s mixing multiple songs together as I’ve definitely heard Jingle Bells mixed in to most of his songs since Mom taught him that last winter. Mom also swears he whistles the Death March in his remixes (not the one on this post though). Since I have friends all over the world and it is possible that Corbin is not singing an “American” song, I’m hoping one of you will know what it is!
