Isn't it called tumbling ? It is with pigeons, in fact some are sold on
the basis of their tendency to tumble.

I've often seen domestic pigeons do similar things in flight. Most of
them don't do it very often, so I've assumed the ones that do are at
least partly descended from the roller and tumbler varieties, which are
selectively bred for these traits, and I assume the ability to perform
tight loops and sudden swerves were originally for escaping raptor
attacks.
I could believe that might apply to a cockatoo, but maybe not a goose.

I've often seen Sulphur-crested Cockies do this sporadic movement when
they are coming into land where they have this jerky movement from side
to side. Could this be them whiffling to reduce speed?
