In this I tend to agree with Dr. Martin.  I do not think that
a ground-level origin of flight is plausible.  (The *best* such
scenario I have ever seen is the one suggesting that the proto-
bird used its "wings" as nets to catch insects - and that one
is none too convincing).

All known mammalian flyers and gliders are arboreal to one
degree or another, or at least show signs of arboreal ancestry.
