It would seem so, re the skies.  Weather that will result in the death
of an albatross or pterosaur won't faze a pigeon.

Not as true as one might think.  The wingfinger is folded up inside the
elbow and doesn't stick out.  The outer phalanges can hug the sides and
back fairly closely (whether capable of active flexure or not).  There
really aren't all that many loose bits fluttering about.  It is true
that they do not become totally invisible as with a bird.
