Prairie dogs are both an annoyance and a danger for ranchers. They dig boroughs in pastureland that cattle graze on, and also eat grass that is needed for livestock. 

Deer and antelope can eat or damage grain in the field, grain piles, and haystacks.  This mainly happens during a harsh winter. They also eat newly sprouting crops. 

Coyotes and fox often prey on weaker small cattle, sheep, or chickens.  

Farmers are most annoyed by black birds. They flock through Lyman County in early fall, when sunflower heads are dry, and the seeds are easy for the black birds to eat.  They eat mostly sunflowers, but also feed on milo and millet.
