Bob,
The fourth best piece of “equipment” is distance to subject.
The Canon 100-400 4.5L IS zoom is common among bird photographers.
You wont use the 100 end of the range often except for cassowaries.
Being a zoom it is not as accurate as a prime but this is a function
of distance. If the inaccuracy subtends an angle less than the pixel
size then it doesn’t matter, which means you will get a sharper
picture from a $2000 400mm zoom at 2m than you will get from a
$10,000 600 prime at 20m. Filling the frame & using all the pixels is
the secret to high resolution shots so get closer.
I havent used the Nikon but I have found the 100-400 f5.6L focus
sufficiently fast & accurate. I would expect both to 'hunt' on spot
focus if not aimed directly at the subject. This is the main reason
you will have problems with slow focus with any lens.
The Canon 450D will be cheaper & lighter but less capable in higher
ISO range but this would be my trade-off instead of a cheaper lens.

Thanks to you all!!
Much appreciated, excellent information has been forthcoming. And
the issues
I should consider.
It seems that for my needs / desires (budget) the way to go is with
the one
generation ago body, i.e. Canon EOS40D or Nikon D80 together with the
100-400 IS or 80-400 VR lens. Still likely to be just over the
$3000 and
without any spare battery, filter, tele-converter, bag, etc.
Comments I have seen on the Nikon 80-400 VR lens is that it is slow to
focus. Many user reviews have mentioned this. Is this the same
with the
Canon 100-400 IS? Any experience?
Regards
Bob Cook
