I used to have a lovely cockatiel, He used to let me know when someone was at the door by screaming his lungs off He copied the dogs barking lol.
He could talk very very clear and said a number of words like hello baby and good morning darling, He did the wolf whistle alot aswell lol, He used to sing this terrible tune only he thought was fab

Sadly he died with a chest tuma wile under anisthetic at the vets, He nearly made it but as they was sewing him up he passed away
The vet team was upset because they said he was quite a charming little man, They said they never had one in the vets as clever freindly and talkative as him. I still have he's fav braclet that he always carted around with him .
