I'm 99% those definitions are from a book called Dragonology (as in 100% they are in that book, 99% sure OP got them from there). I used to have a copy when I was young and still use those same definitions.

It's written like a textbook/victorian field notes thing. Actually a pretty good book for imaginative kids (and, if I'm being honest, adults too. I might actually go see if it's in the house somewhere.)

EDIT: I assume most of the "information" in that book is generated by the author, but I'm not sure how much of it is just written up from general folklore/mythology. I'd say very little based on how specific and categories the stuff is compared to folklore and mythology, which are almost always HUGELY unspecific about descriptions on... anything.

This was the first. They've covered a number of topics since. The books are kid-friendly, but the sheer amount of going the extra mile for the sake of making something cool and artful I feel would grab anyone's attention.
