I literally just told you, size. You can go look up the exact ship specifications if you want, the Raptor is a small scout ship, the BoP is a mid-size warship, and the Warbird is a full-sized warship.
Also what are you even talking about, what came into canon first? Of course the Bird of Prey, its from ToS, I do not understand how that is relevant to the discussion.
Uh huh.
Which do you think was introduced to the canon first?
And what is the difference in Klingon between a Raptor and a Bird of Prey? Or do they simply go on context?
