When I was 12，something happened(发生)to me that changed my interest．

　　We lived near a wood and every evening birds would sing beautifully in the trees．1 wanted to catch a young bird and keep it in a cage(鸟笼)SO that 1 would have my own singer．

　　I did get one and put it in a cage．At first the bird flew about in the cage．but after a while it became quiet in its new home．I felt very happy and looked forward to some beautiful singing from my little singer．

　　On the second day，its mother flew to the cage with food．The baby bird ate everything．I was pleased to see this．Surely the mother knew better than 1 what her baby liked．

　　The next morning，I found the bird dead．What happened? I had taken good care of the bird．
　　or so I thought．

　　Arthur Wayne told me the reason．“A mother bird，finding her baby in a cage，will sometimes bring it poison berries(毒草莓)．She thinks it is better for it to die than to live in a cage．"

　　Never since then have I caught any living bird and put it in a cage．
