I reckon a Pelican would easily be able to get a skateboard rolling. I'm just now sure the best steps to proceed testing it.
I'd try a skateboard at the top of a hill and see about getting a cockatoo to somehow get the board to roll under it's own propulsion so it can sit back and enjoy a ride down a hill. That'd be the way I'd try if I wanted the bird to do it repeatedly.
