Sometimes people use the Haedongcheong (Northern Falcon) as proof that Joseon was uncivilized

'They could have easily increased their numbers just by catching a male and female pair and letting them breed, but the uncivilized Joseon people didn't know that and just kept hunting them down'
I have often seen people saying this on the internet.
Of course, it is not that people in the past didn't know something so simple (if they truly didn't, the concept of livestock wouldn't even exist);
a falcon chick that is handled by humans before learning to flap its wings from its mother will never know how to hunt for the rest of its life.
Naturally, a falcon hatched from an egg won't know how, and a falcon taken from the nest too early also won't be able to hunt.
There is a word in French, "niais," which means 'fool.'
However, the etymology of this word is 'a falcon chick taken from the nest too early.'
The term "a chick taken too early" itself can mean 'fool,' and it also implies that the person who took it without understanding such logic is a 'fool.'
To summarize, only 'a falcon that learned to flap its wings from its parents but was taken at an age where it wouldn't reject human handling' could be raised as a hunting falcon.
That is why, whether in Goryeo or Joseon, people were absolutely obsessed with the Haedongcheong.
