You're welcome! The more people know that it's okay to do so, the more little fledglings get put in safer places after falling. :)

The only danger comes to you if mom or dad takes umbrage to you trying to move them, but that's generally minimal (unless you're dealing with blue jays). Most birds recognize that dive-bombing a human is a silly endeavor, and will stay out of the way whilst you move the fledgie to a safe spot :)
