Macky (short for Mackenzie), is our 5 year old male african grey. Often times at night, we hear him whispering or talking softly to himself as he's falling asleep. My husband and I call it night-time voices as he seems to say all the things he normally says, only at a lower volume. He does this while we are watching tv at night. Not after all the lights are out, and it's quiet. I was just wondering if anyone else has an african grey that does this.
