OP is shooting in RAW and using Topaz denoise software.
OP is getting ISO pushed to 5000 to 8000 with his desired shutter speed and aperture using the DFA 150-450.
OP is looking for ideas, things proposed have included getting closer (always a challenge) to use a faster lens, using a flash perhaps remotely triggered in a flight path that is commonly used, etc.
It has also been suggested that the OP post a couple of files and links to RAW files and full EXIF to help people see the noise problems he is seeing to verify these are in line with expectations.
In short - he seems pretty aware of what he's doing just a bit less familiar with the K1 than he likes and he is not happy with the level of noise at the current settings. ISO 5000-8000 is pretty challenging but for his shots he isn't happy with lower shutter speeds which would permit lower ISO.
I'm stumped - other than faster long lenses (400 f2.8, 600 f4) there's not much I can imagine that will help. Maybe the EXIF if samples are posted will help point people to some solutions.
Nice summary...thanks for going to the trouble of sorting it all out. The solution matrix is as you noted, with the possible addition of considering support options such a gimbal to allow lower shutter speeds.
As noted above, ISO is no substitute for light and without adequate light, noise dominates.
Addendum: On the bookshelf upstairs is a fine art coffee table book titled "The American Eagle". It dates from the late 1980s and contains bald eagle photography by my friends Tom and Pat Leeson. Photos for the book were taken in all seasons with Nikon F3 manual-focus bodies and Nikkor lenses in the range 20mm to 600mm with occasional use of a 1.4x TC with the 600mm. Films used were Kodachrome 64, Fujichrome 50, and Fujichrome 100 slide films. Most of the tight shooting was done using blinds, both tree-mounted and ground level with almost all work done on-tripod. When working in the blinds, the two would alternate 3-4 hour shifts. Tom and Pat had no concerns about noise, though they had severe constraints regarding light, compounded by shooting at "low ISO" with no option to push in post. As might be imagined, most of the photos were taken at shutter speeds somewhat below 1/1000s, depending on weather and required DOF. I have no idea what their keeper rate was, but do know they typically shot about 30,000 frames per year back then.
Why bring my friend's work up? Without high ISO, skill in the craft and time with the subject produces results.

(...can't remember the last time I shot 1/1000s or above...seldom uses auto-iso...has ISO ceiling on K-3 set to 3200...)
