If I wake him up too early in the morning, he says “night Diesel” which means Im not ready to wake up yet. He gets about 12 hours of sleep every night.I find it interesting that yall are getting these pictures of your birds sleeping. I never see Diesel’s eyes closed. I catch him yawning, and when he gets sleepy he says “night Diesel”. But when we uncover him, his eyes are wide open and stay open all day long. I have never caught him sleeping like that. Its super cute. Diesel is wide eyed and wide open from dawn to dusk
