Hi sg, I think that might be kakapo you're thinking of, kea are great fliers altho they do a lot of walking about as well. I loved rockdoc's description of them as rolling along like sailors, that describes perfectly their hilarious rocking gait. They are incredibly cheeky and curious and will peel the rubber off your wind screen wipers and window seals in no time at all if they feel like it.
Farmers used to kill them in the bad old days, in fact the govt actually paid a bounty for their skins at one point because they have been known, very occasionally, to peck at the backs of sheep to get at the fat, which results in a most unpleasant death for the sheep. Wisdom has prevailed for a long time now and they are fully protected- recognition that they have been here for 20 million years, and humans and their livestock for 200...
Kakapo are another matter, they must be among the most bizarre and lovable birds on the planet. They are unique both in being a flightless parrot, and nocturnal. They are very friendly(not a good idea when humans, cats, rats and ferrets turn up!), and have the most ridiculously elaborate and impractial courtship rituals imaginable. In short, they could only possibly have evolved in a crazy, isolated ecosystem with no mammalian predators at all.

to see a kakapo that was accidently imprinted on humans when it was raised as a chick many years ago. Techniques have since improved, so that this doesn't happen anymore, but as a result of his upbringing Sirrocco the kakapo is not interested in other kakapo at all, only humans, and takes a particularly amorous interest in the unfortunate biologist in this clip
Well I guess I have derailed threads worse than this before, but surely not by much. Apologies, and back to the pressing matter of some frozen rocks in the south atlantic
