100-400mm f/4.5-5.6 L IS ? .
Depends on the body. The outer AF points on Canon 1-series bodies are spec'd to AF with a maximum aperture of f/8 or better (so you could get away with a 1-stop teleconverter and retain AF), but exceed your budget; the outer AF points on a 40D are not spec'd to AF at anything worse than f/5.6, so you'd be using manual focusing with any teleconverter..
Better. will spend over $100o for camerabut not several thousand..
Same issues with nikon 80-400 VR lens..
Also f/4.5-5.6, with similar issues. f/5.6 appears to be the spec'd limit of the Multi-CAM 1000 module that seems to be found in the D80, for instance...

A 1.6 crop sensor body, 400D or 40D, will give you the most 'reach' with the 100-400 mm lens, but as Leejay has pointed out, they are not spec'ed to AF beyond f/5.6. A 1.3 crop sensor body will AF to f/8 (lens plus 1.4x teleconvertor), but even a used 1D II or 1D II N maybe more expensive than you are looking for..
With some non-Canon teleconvertors, the conversion factor isn't reported to the camera and a 400D or 40D will autofocus, although not as effectively as it would with wider aperture lenses. It is also possible to tape some of the contacts on teleconvertors that do report info to the camera and have the camera attempt AF..
You could also look at the Canon 400 mm f/5.6L. At the shutter speeds needed to shoot birds IS isnt a necessity. The AF problems are the same with a 1.4x extender, but the prime is sharper fully open than the zoom..
It will autofocus (not very quickly, and will hunt a lot if not in good light). You just can't use Canon/Nikon teleconverters..
Pick up a Kenko 300 DG teleconverter. Optically just as good, and they don't report aperture so you can AF...

So just for the information. what model camera would work with teleconverters and auto focus with the 100-400 lens or the 80-400 lens? never mind the cost..
I have seen people using teleconverters with these lenses but not sure which model camera they have. 1.4 teles I guess...
This would be a good combo, and the total price is within your $15,000 budget.
1,500 each for lens and camera. for a total of $3,000 plus teleconverter and other stuff. not $15,000!..

Any Cannon 1-series camera: 1D, 1D II, 1D IIn, 1D III, 1Ds, 1Ds II, 1Ds III..
I misread the 1500 vs. 15000.Still, for 15,000 that would be an awesome combo (LOL)Warm regards,DOF..

40D will NOT auto focus beyond f5.6 even with non-Canon converters or tapped contacts - this is discussed in several threads on the 40D foru..
That said, for birding I'd recommend the 400 5.6 L - the IQ from a prime lens is a big plus and it's the only prime long enough within the specified budget...
