He's pretty! Sixteen yrs. old is very old for a cockatiel! Their life-span really is 15-15 yrs + but not that many make it to be so old. I'm glad you're taking such great care of your baby! I love the pictures of him with the dog!! That's so sweet & cute. It made me think of my poodle; she's real good with the virds too. I hope my tiels live to be that old! My oldest is only 2 right now.
