Living in southeast Missouri (bootheel) I've seen plenty of fudging on limits of all kinds of animals/fish/ birds, though not to the extant others have written here. Most generally, the excuse is "I eat all that I kill, unlike out of staters." I have seen more than one out of state dove hunters spend big money on gear, ground, & vehicles & dogs. Shoot their limit in 30 minutes, take a bunch of hero photos, then pack up, drive down the road, dump their birds in a ditch and drive off. Sometimes they come back, sometimes not. Rabbit hunters with thousands in their dogs go to an abandoned homestead and massacre rabbits, tossing any they can't give away. Duck and snow goose hunters as well. It is what it is.
