节目简介

我们从平常的简单观察和从诗词歌赋里了解到的，鸟儿就是成双成对，忠贞不二的。其实啊，鸟界的“爱情”，本质上是一场场关于能量、基因和生存的精密计算。
咱们别再羡慕朱鹮的“白头偕老”了。当年就剩下了7只的朱鹮能绝地求生，能靠深情解决么？那就是因为高昂的育儿成本逼出来的“双亲合作KPI”。一旦单飞了，娃就得凉凉。在人工繁育基地里，为了防止近亲繁殖导致的一些问题，工作人员还得强行给它们“办离婚”，按DNA档案重新“包办婚姻”。
至于咱们传统文化里的“爱情鸟”鸳鸯，就更颠覆咱们认知了。什么双宿双飞，白头偕老，雄鸟在雌鸟下蛋后就立马“离家出走”，雌鸟也不省心，也是个厚黑的主儿，有时候也会发生巢寄生的行为。
还有中华攀雀，一个钢镚儿沉的小鸟，在繁殖期要面对着“囚徒困境”。为了能多生一窝，爹妈随时准备跑路，导致16%的巢直接变成“双弃巢”。在鸟类世界里，没有海誓山盟，只有“演化博弈”和“适合度最大化”。听完这期，估计你可能无法直视公园里的那些秀“恩爱”的鸟了。
