Did you know that birds could be "property owners", too? In spring, the male robin (知更鸟) looks for a
place to build a nest. A tree neara green lawn (草坪) that has many worms (虫子) suits him best. When he
finds the right place, he sings loudly. He tells other birds that this place is his property.
At the same time, other birds are choosing places for their nests. A robin does not mind if swallows nest
nearby because swallows eat insects. They leave his worms alone. But other robins are different. They would
eat the worm supply he needs for his own family.
When another male robin comes near, the robin owner sings to wam him away. The property owner looks
cross and fierce (凶猛的). He raises his head feathers and holds his tail high. If the owner cannot frighten
away the new robin, he attacks. The two fight until one is the winner. The new bird often gives up and flies
away. So the first bird has defended his property. He now has the right to build a nest in the place.
