We could all see the Murray Uiver slowly moving back, but now all the water was gone . I couldn’t believe that the Murray had dried up, not one drop of water left.
One morning I went down to the river to try and catch some fish when I saw my boat high and dry (搁浅) on the bank . I rushed down the river and saw all mud—no water . The fish were just lying there, dying . I looked up to see if my friend was there . There was the nest but no eagle（鹰）. I called out to her with my special whistle which I made out of steel.
Suddenly a big shadow came over to me and the eagle landed in her nest and gave her young the food she was out getting while I whistled. But then I suddenly noticed she was getting thinner and had a bit of sheep’s wool in the side of her talon（利爪）. It was deadly quiet by the river bank , except for some sound from my dog. And also I couldn’t see one native animal or bird.
When I walked inside the kitchen. Mum and Dad had sad looks on their faces. “It’s time for us to move ,Son, because the river can no longer provide for（养活）us,” said Dad . I ran out of the kitchen door with tears in my eyes , and down to the river bank, to my favorite spot. I said goodbye to my eagle , crying.
When it was time to go , I saw my eagle fly up into the air with her chicks in her talons , going away to try and find another home ,just like us.
