Tiels do love to beak and if you do a rhythm on a jar lid, he will learn it. My tiel, Penny is two and 1\2 years old. He is a master at rhythms. He sounds just like a human drummer! He beaks on the cage floor and his food cup. He is very intelligent. He beaks a rhythm and then waits for me to repeat it exactly as he did it. When I do repeat it, if it is like his exactly, he will do a different one. If I don't do it like he did, he quits playing and goes and sits on his perch. If I do it right, he creates another different rhythm. Sometimes we can get to 5-6 rhythms. It is a fun game for us!!
