Answer: Doves place one foot in front of the other and walk. Cardinals， like other perching[棲息的]

song birds， cannot walk – they hop. Notice the footprints are side by side， a result of hopping.

答案：鴿子是前后腳走路的，而紅雀跟其他會唱歌的鳥一樣不會走，只能跳。注意觀察腳印是并排的，是在地面跳躍產(chǎn)生。

One of these two birds left footprints in the fresh cement. The cardinal[北美紅雀] accused the dove， and the dove accused the cardinal. The birds are wearing identical[完全相同的] sneakers[運動鞋]. Why does Slylock Fox strongly suspects the cardinal is guilty?

這兩只鳥中有一只在還沒干透的水泥上留下了腳印。紅雀指責(zé)是鴿子干的，而鴿子則把矛頭指向紅雀。它們都穿著同樣的運動鞋。為什么狐貍偵探深信紅雀應(yīng)該負責(zé)呢？
