My Sister Used to have a Cockatiel and as I Whistled the Theme Song from THE GOOD, THE BAD AND THE UGLY, He Would Cock his Head and Listen, Then He would Pace Back and Forth on the Top of the Couch Trying to Repeat this Relatively Complex Tune.
I Also Taught Him to Crow Like a Rooster. He Wouldn't Do It for Anyone Else But Me; I Could Be Gone for a Month and When I came back and Crowed LIke a Rooster, He Would Answer Me!
Birds and Animals are Far More Intelligent than We have Been Taught!
God Created the World. And it was GOOD! (How Could it be Otherwise if God Created It?)
