Or, I suppose, it could just tilt itself, so that its forestroke becomes an 
upstroke. The tail base is flexible enough to prevent the tail from touching 
the ground.

Well, yes; it's 20 years old. :-) And the specimen it announces is not a parrot 
either. Last I heard, it could technically be a parrot if it's specifically a 
lory, but it's far, far too old for that; it can't be a stem-parrot, because 
those (known from the Eocene) didn't have parrot-style beaks in the first place.
