Well, did you know that in several laboratory experiments scrub jays, relatives of the blue jay, hid their extra food more cautiously when other jays were around?

对了，你知道吗？在进行的一些实验中我们发现当有其他鸟在的时候，蜂鸟——蓝鸟的近亲，会将他们剩余的食物非常小心的藏起来。

In fact, if another scrub jay was visible when the first jay buried its food, the first jay was more likely to dig up the food later and rebury it in another location.

事实上，如果另一只蜂鸟看到了第一只蜂鸟藏食物，那么第一只鸟则很有可能随后把食物挖出来在重新埋在其他地方。
