Control functions (turning, braking, etc), leaping, WAIR, etc

In most cases, yes, a jump is more effective.  Even most running launches 
actually end in a leap.  If you want to see quick and easy evidence of this, 
take a look at stills of launching waterbirds - if they were actually building 
up launch speed and transitioning to wing-dominated propulsion gradually, then 
the water displacement (i.e. splashes) would get smaller over the course of the 
run.  In actuality, they tend to be quite consistent, until the last one - 
which is nearly always much larger than the rest.  Animals do not launch like
