In a desperate effort to burn away what little spare time I
have, please fwd the following to DML. I don't think
anyone else 'properly' answered the question.

I was wondering if anyone knows if the above extinct parrot
was flightless or not? The info I have seen says both
flightless and could fly.
The real :) answer to the question is somewhat complex, in
that parrot experts have been divided over the answer.
Hachisuka (1953), Holyoak (1971) and others assumed
flightlessness on the basis of the sketch provided by
Newton & Newton (1876) where short wings were depicted.
But Hume (2003) was able to show that the original
drawing reveals longer wings - and wings long enough to,
theoretically, enable the bird to fly. The osteology also
indicates a flight ability, plus there are illustrations showing
the birds in flight (see Hume 2003).
So, despite contentions that _Lophopsittacus_ was kakapo-
like (and, in any case, kakapos aren't completely flightless),
the evidence does not favour flightlessness. I say all of this
with an illegally borrowed copy of Julian Hume's phd thesis
to hand: it includes tons of new data on Mascarene parrots,
most of which will see publication soon.
