My little feathered baby, Casanova, is gone.

He was just a few months shy of being three years old.
He seemed perfectly fine yesterday, was eating and drinking and talking like normal, but then tonight I find him at the bottom of his cage. I'm really not sure what happened and I can't help but wonder if somehow, I'm to blame.
I know I wasn't the perfect bird mom, but I loved him and I took care of him the best I could.
Goodbye, little sweetheart... I love you and I miss you.
