Only birds have bird beaks! (Turtles have beaks too, but not bird beaks).

That sounds like a tautology and it is the way I stated it, but it is true that the particular morphology and ontogeny of the bird beak is found in birds only. This would be trivial were it not for the fact that many other adaptions also key for birds are found in related non-bird dinosaurs.

Question about beaks and this comment

All birds have them, no other species do.

from the article. I’ve read articles about squids with “beak” used as

The mouth is equipped with a sharp, horny beak …

Is “beak” used purely as a descriptor here or does it have some other meaning?

Recent research provides some important information necessary to begin to address this question, but this and other parallel research, on the other end of birds (the tail) also serve to tell us something very important: when it comes to understanding how evolution actually happened (of birds or anything else) we are standing at the very start of a long and uncertain journey. In other words, we are nearly clueless.”
