At 42 years old, Walnut was considered geriatric for her species. She far surpassed the median life expectancy for white-naped cranes in human care, which is 15 years.
(Avg life expectancy of humans without tech is prob 20, but humans could live to 100+ thousands of years ago, nothing changed, we just systemically eliminated the factors in our environments that cause non-old age death (with cancer, neurological, and cardiovascular problems remaining the last lines), eg food quality, vaccines & healthcare overall, killing & sterilising every other ecosystem around us, you know, the usual)
Unfortunately there are many counterexamples, large animals that live long in the wild tend to have shorter lives in zoos, like elephants, hippos, and monkeys.
She lived almost 3 times the average life expectancy for her species!?! That’s genuinely insane! Imagine a human living to 180 years old!

Single women live longest
This happens quite often with animals in captivity. Nature is dangerous (and health care is important!)

15 seems to be the captivity average though, not natural average.
Fair point, I was just speaking generally, and that she actually lived way longer than most of her species since most aren’t in captivity
White napped crane life expectancy in the wild is unknown.
So it sounds like you didn’t know that, either.
