   How fast is fast?  Are we talking about speed in a short burst, or
sustained flight over distance?
   We can assess the long-distance speed of those waders which have
have  geo-locators attached to them.
If we could attach such a thing to Swift Parrots, we could trace
departure and arrival on migration (assuming the locators could be
I don't know if Swifties have even been banded, though they should be.
    When we trace a bird's speed by following with a car, this is seldom
over more than a kilometre, often very much less.  Most birds are
capable of bursts of high speed when escaping - or when hunting, in the
case of raptors. Long distance travel is another matter, whether on
migration or commuting between roosts and food, as Galahs and Ibis do.
   On migration, I would back Swift Parrots, and as commuters, Galahs.
Their flight looks easy, rather gull-like, without wild flapping, but
they can keep it up for a long way.
