Just as the microraptorids would start gliding out of trees when
acting as groomers and using a stiff tail to flip clear of the feet of
their host when detaching.
A large and highly pointed claw makes for a relatively poor climbing
crampon on bark, but should work well on hide and integument. One might
even be able to dig enough of a gash to get some blood (if one wanted
to move from symbiotic to parasitic feeding)...
The true origin of flight...?
