I don't think we can all agree to this, sorry.  Sure, Microraptor was utilizing 
its feathers in an aerodynamic fashion, but it is not at all obvious that is 
was the type of flight that you are thinkng of when you say it was incapable of 
a running takeoff.  Everyone thinks that the ground-up origin of flight means 
learning to fly from the ground, rather than just, say, leaping after prey.  As 
for why not trees, because the ARE NOT built for it.  Sure, they could get up 
in trees, just like goats can, but they aren't built to habitually utilize 
arboreal perches in their prey aquisition.
