案例简介：查理·汉密尔顿·詹姆斯的照片 | 一只成年雌性欧亚翠鸟带着一条鱼飞向她的巢。翠鸟在隧道中筑巢，他们用尖锐的喙挖掘到河岸。他们的小鸡在隧道尽头的一个房间里长大，由父母喂养不到一个月。在这里，母鸟已经把鱼放好了，这样她的一只小鸡就可以把它整个吞下，然后先去。

Kingfishers nest in tunnels that they excavate into river banks with sharp beaks. Their chicks are raised in a chamber at the end of the tunnel and fed by their parents for just under a month. Here the mother bird already has the fish positioned so that one of her chicks can swallow it whole and head first.
