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.
