<< Now, maybe I'm misunderstanding something here, but I thought that this
behavior was being postulated for the early evolution of flight as would
have occurred in, say, basal dromaesaurs, and that Archaeopteryx would
have already progressed "past" this stage in flight evolution. Thus, I
didn't really see how this was a relevant point. >>
I don't really see how flying-up-the-treetrunk must be considered a "stage"
in the evolution of flight. It is a behavior open to any bird with suitably
developed wings, whether it was on the way to acquiring flight, secondarily
losing flight, or fully capable of flight. Oh, well, I'll have to wait until
the journal arrives in my mailbox next week.
