You think so. But after 2 hours in the field you begin to re-train your eyes to look for movement rather than the animal itself. It comes back fairly quick. Some fields to the layperson seem barren.. to a varminter they are teeming with targets. When gopher season starts, and i am driving, i really have to concentrate on the road. The urge is that strong
I can totally relate...
I went ground hog shooting some years back near Owen Sound Ontario with a friend who ran a local gun store. He kept pointing out ground hogs in the fields but it took me quite a while to "see" them.
Once I got it, I can now spot them anywhere. I once saw a ground hog in a vacant lot in Detroit on 8 mile road of all places.
I had another friend in the car with me one day as we drove over the train tracks where I spotted one.
I pointed to it but he could not see it, so I stopped the car and we got out.
As we walked toward it I pointed to it and he still could not see it.
We got closer and closer and still he couldn't.
We finally got to about 10 feet away when he finally saw it because it moved and ran into its hole.
It's funny but you just need to learn how to see them.
The same goes for deer.
Like Got Juice~varmint hunting IS my main "gig", and I spend more time at it than anybody I know. lol Alberta gophers when time/$ allows...but Ontario groundhogs every spring/summer. Never a big numbers game, but like anything...stick with it, you learn allot along the way and success rates trend upwards.

As for spotting them~with gophers...it's mostly movement. With groundhogs, it's either color (THEIR color vs. the lush/green hay or soybeans) but more often, inconsistencies in the field itself. Hay cutting equipment rides-up on the pile of rocks left when a groundhog digs a hole...so look for patches of taller hay to reveal where there is (or was) a groundhog hole. They're FAR more wary than gophers in the west, so glass a field looking for either groundhogs themselves..or patches of taller hay. If you find the latter, get set-up and study the patch of hay (with a higher-power spotting, or rifle scope) for at least 10 minutes. Just showing up on a field (even 200+ yards away) can scare them down their holes but eventually...9/10 of them will "periscope" up partially within 10 minutes to see if the perceived threat is still there. This is the toughest part for impatient groundhog hunters, and why some people I invite only ever GET the one invite. lol The waiting period is the wrong time to be fidgety, you want to be nearly motionless...which is why I run a higher-magnification scope. I can study a hole/mound through it...with my finger close to the "go" button.

Laying still in dried-up cow patties, in a hot sun, often humid conditions~not everyone's cup of tea.

It's how you get it done though.
Trade secrets revealed! lol
