A question  for the list.
My father was inquiring about why different cockatoo species fly the
way they do.  Sulphur-crested Cockatoos have the seemingly
unco-ordinated double flapping (with no apprent pattern) while
Yellow-tailed Black Cockatoos have a very "lazy" gentle flight pattern.
I'm interested in people's thoughts on the matter.
Do the different patterns confer an "advantage" or are they related to
movement and habitat or flock structure.
Is there any explanation at all??

As a top of the head, totally unscientific idea, I
would suggest the flight patterns are linked to the birds' brain
patterns.  It would be interesting to see if there were a correlation
between the way a species
calls and the way it flies - cockatoos with discordant calls fly in an
uncoordinated fashion, while cockatoos with harmonious calls are poetry
in motion!

Indeed LK I totally concur ! 
Has any one else noticed this ?

What I have picked up on lately is when my local Rainbow Lorikeets are
in flight and utter a call they increase their height in flight ? and
the call matches the wing movement ?
anyone ?
