She still needs a name.

Those bit claws up on her arm can flick up like dromaeosaur kill-claws to look more menacing and maybe do some damage if you get too close.

Again, only her uber half-dead form. Changes would include air sacs to facilitate more efficient oxygen extraction -Wendigo probably still needs it- but the increase in activity means an increased metabolism. Which means more food, so she'd only fly if she had to and after would have to get dinner. A lot of it.
