Can anyone state definitively what the speed hierarchy is w/ these forms (plus condor)? Is it just a dex check? My mental ordering (backed up by zero data) has always been roughly:

Hummingbird
Falcon
Golden Eagle
Vulture

But I've no idea where vampire bat, wasp, owl, and condor fit into that list. If it truly is just a dex check, then (absent condor) it should be:

Hummingbird
Tie: Falcon/Eagle/Bat/Vulture
Owl
Wasp

Also: what are the restrictions on final-tier air forms with respect to seeing into (and/or flying into) rooms from high altitude? Feel like I heard certain forms have restrictions while others don't?
