Either camera can do the trip you plan. Personally I would take a waterproof pocket Nikon on the rafting tour.
As far as wildlife goes and birds in flight, the D500 is a perfect match. I have used mine for years using the Nikon 200-500 lens.
The dual focusing system in the D500 is also in the D850 and D5, it is not in the D7500. Also you get 10 fps with the D500 which is advantage ous for BIF to get just the wing positioning necessary, yes, fps is very important.
Just the information I wanted to hear Bill. Love your photo. I want to be ready for mating and nesting season.
