I agree entirely. This is why, in a phylogenetic analysis, *all* of the
relevant information is considered simultaneously. The dinosaurian nature
of birds is supported by several independent analyses relying on a large
body of data, not on single characters that, as you state, can be
misleading in the wrong context.
