We generally turn on our red lensed head mounted lights the minute we shut the truck door and turn to walk away. That has caused us to kill foxes as we walked to our setup by virtue of just seeing them mousing along a fence row down the field or somewhere along the way, you will pick up their eyes at a tremendous range then just sit down right there and call em to you. Once you hit them with the light, keep it on them, that way you are shielded, sort of hidden behind the light curtain. The red won't bother them.
It also helps if you stumble upon some skunks in their mating process(been there, done that). This actually happened to myself and two other guys this past Feb. Walking up a powerline road in the middle of the night, they assumed they had the right of way, so we let em have it.
