You will only get a minimal gain at 200hz with a parabolic.
I don't even use my 32" on the large owls.
I use my mkh-110's for the big owls mounted within a shopvac filter
element. The me-62 will work fine for you mounted under an umbrella
to give it water protection. For leaving unattended I would favor a
less noticed mic and smaller to make ease of water protection such as
the wl183 lav omni.
For in the field at night the senn shotgun me-66 or 67 will be your
favorite.
You don't have to be too shy about walking up to a Great Grey as they
are not that timid.

will get an increase in directionality, Which is fine when you are
there and can direct the rig at the owl, but not for passive
recording. Unless you can identify somewhere the owl is likely to call
from I would guess most of the time your mic maximum gain axis won't
be in the direction of your target.
