Re: Quetzalcoatlus ecology (was T. rex vision)
I agree with Mike. I just don't see any way that quetz could be capable of
a rapid strike. Plus, the 'beak' doesn't have a sharp or pointed tip.
I too, have noticed a lot of confusion between convective and dynamic
soaring, and the morphological biases associated with them.

Like Jim, I also find the stork analog unlikely. I think Darren (despite
being quite an insightful guy) has overlooked how storks actually feed;
their feeding behavior actually has a lot of similarities to that of
herons. In fact, storks sometimes snap up small birds that are airborne.
Storks are rapid strike predators. Opportunistic yes, but not dippers.
It is also worth noting that Dr. Naish pins some of his conclusions on
assumptions about Quetzalcoatlus flight parameters (and flight mechanics
in general) that are in error. For example, he seems to confuse the
adaptations for gliding and convective soaring.
