Can Any Flightless Birds Climb Trees?

Question

Silly question...
but...
me and some friends were discussing weather a penguin, a duck, or a flamingo could actually physically climb a tree...

Answer 1

Yes - the kakapo (no, I'm being serious)
Check out this for a list:
Flightless
nocturnal
the only flightless parrot
the heaviest parrot
climbs trees
has almost no flight muscles, so it parachutes (badly) from
tree to tree (or from tree to ground if it gets it wrong)
the can live for more than 60 years

and if you don't believe me, try
