Does it show a partial change from a reptile toward being a bird or is it a bird with what you think are reptile characteristics. A fully developed critter ain't a transition. Sorry. I know you want to confuse the two things and point to this as transitional; but, it ain't transitional. I believe this is a repetition at this point.
You cannot impose this upon evolution. All evolving creatures are fully developed, even while their populations are gradually morphing under environmental pressure into something utterly new. All the forms along the way are adapted to their environment, competitive, functional, "fully developed." People who suggest that a transitional has to be some kind of obviously unfit freak do not know what the theory of evolution says.
Don't be dense. Regardless of what a critter's ancestors or its descendents look like, it is "fully developed" for its particular ecological niche at its particular time. All organisms, lest they go extinct, are "transitionals" because the demands of the environment change. That you cannot wrap your mind around these simple concepts does not bode well for your taking anything new out of these discussions.
