     We could all see the Murray River 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 support 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.
