This is my point,
If you have one body dedicated to your long prime, there are also going to be opportunities to get other things with a shorter lens.
Having both bodies along will allow you to get those other shots without switching lenses.
I've never shot sandhill's before, but used to live along the Missouri River and get Canada's and snow geese (huge flocks), long lens was OK for picking individuals out, but the flock needed wider lenses to capture the scope. I'd not want to be locked into one focal length for much of my time there, you've got the gear, go prepared.
