Hello,
Welcome aboard. I only just joined myself, plenty of friendly knowledgeable people here. A friend keeps Cockatiels, he had a hand reared one on his shoulder, and after a few frothy chops ( slang for sherberts or beers ) went outsde to take in the washing. Off it went. We put up missing posters at the surrounding shops, and we got him back. He flew a few suburbs away, and saw a man. Landed on his shoulder no doubt thinking he will take me in and feed me. He didnt want a bird, so took him to a local Pet store. Now they all look about the same, but this one had been taught to whistle the Adams Family theme music. Almost, any way someone saw the bird, and heard the tune. When he saw a flyer he rang and the bird was recovered.
