First of all, yes I did forget Gargwa, so I commend you for reminding me of that lovable fellow.

Secondly, I'm starting to think maybe I should keep my opinions to myself. Most Bird Wyverns are more wyvern than bird (hence the name Bird Wyvern, and not Wyvern-like Bird), with predominantly reptilian features with a few avian characteristics here and there. However, monsters such as Hypnock, Forokururu, and Qurupeco are distinctly more avian than reptilian, especially Forokururu as I previously mentioned. Forokururu is entirely covered in feathers, leading me to believe that it has lost most of its reptilian traits and is now on the path to evolving into an entirely avian branch of monsters. Similarly, of course, to the progression of reptile to bird as seen in today's fossil record.
