Mr. Ellis is very old. He has seen many changes in his hometown.
He knows that things are different now. But he never forgets the old days. He likes to talk about them. He often talks about his favorite birds , the robins (一种小鸟—鸫)."When I was a boy, these houses were not here. There were wide fields and tall trees. Every spring the robins would come. Thousands of them would fly up to the north from the south. They spent the winter in the south. Some would build their nests (巢) in the trees near our houses. Then people started to cut down trees, and built more houses. The robins stopped coming. They couldn't build their nests near our houses because there were no trees."
"Now there are too many houses and too many roads. There are no places for the robins. They don't come any more."
