Hi Akos and others
There are a few movie clips of hovering Kestrels on YouTube:
e.g. http://www.youtube.com/watch?v=31Xw75hAwIc
The ones I've found are European Kestrels, but you can get a bit of an
idea of what they look like.
There are also clips of Black-shouldered Kites - some of these are of
the Australian BSK. This one shows several slight maneuvers - more
gliding and soaring than hovering I think.

Watching clips like these should help you with the "jizz" of the bird
- what it looks like when you see it moving in real life. Chris B and
Belinda both described some of the differences in how our 3 main
hovering raptors look. The best thing is to try to observe this a few
times "in the field" - you will soon get a feel for the jizz and be
able to immediately pick which bird is hovering. They really do look
quite distinctive. If you are lucky you might see BSK and Kestrel
fairly close together (in place or time) and that will help you get a
clearer idea of the differences. Brown Falcon is harder because they
don't seem to do it as much, but from memory their attempts just look
a bit "heavier". I was going to say "cumbersome" but I think that is a
value judgement on what is really a remarkable feat. I can't fly at
all!!

Hi All
My observations of birds of prey on Kangaroo Island have me believe
that
Nankeen Kestrel is easily the most accomplished at hovering,
followed by
Black-shouldered Kite and then the Brown Falcon - which hovers much
less
often than the former two.
