Re: Flightless pterosaur question:



Of course, but that's the easy answer. Some flightless birds do not have 
absurdly short wings. 

What's the threshold for flight/flightlessness?

Could it be found in the pectoral girdle, rather than the wings?

Witness the Kagu:

"The wings are not reduced in size like some other flightless birds, but they 
lack the musculature for flight."
