Studies show that the survival rate for the first year for ospreys is only one-half. Even for those lucky enough to get past the first hurdle, the mortality rate in the second year is near 20 %. You could say that the Creator is very selective about who gets to breed.
根據研究，魚鷹第一年的存活率只有一半，僥倖度過第一關的，第二年的死亡率也達百分之廿，可以說每隻鷹都是造物主百中挑一才得以存活下來。
