Could a bird propel a skateboard by flapping its wings?
That is to say, could they get enough forward thrust to push themselves along, without taking off? Maybe with like a little perch to hang onto...

I'm sure an eagle could even pick it up and fly away with it. I've seen eagles pick up mountain goats.
Yea, but I was talking about taxiing like a plane on the runway.
Surely you can see the energy required to pickup and fly with a skateboard is orders of magnitude greater than simply pushing the skateboard?
Yes, and that's not the question I'm asking.
I'm asking whether they could sustain forward thrust in a standing position, and without actually taking off.
Most likely, yes. If anything, a bird may stand in reverse and flap the wings in front of itself.
But I would expect that its maneuver ability would allow it to do so in different ways ¯\_(ツ)_/¯
