第104期：基因给了起点，童年定了航向 - 你我都是那只被移动过的鸟

身在异乡的你，有没有想过：究竟哪儿才算自己的老家？是你的口味、口音这些？这些习惯又是哪些是刻在基因里，哪些又是后天养成的呢？其实不光是我们人类，鸟也有这个成长的烦恼。

科学家把荷兰斑姬鹟的蛋挪到瑞典孵化，让瑞典鸟当爹妈。结果这“荷籍瑞裔”的小鸟，春天回瑞典安家，冬天去非洲过冬时，落脚点却卡在了荷兰鸟和瑞典鸟的中间。

同窝的黑尾塍鹬，一个在荷兰放飞，一个扔到波兰，最后去的越冬地都不一样。白鹳的幼鸟要是错过了“老司机”的带队，就只能自己瞎飞，还有很多鸟类全有这样的问题。

基因打底，环境塑形，不论是我们人类还是鸟类，最后总会走出一条独属于自己的路。
