MISSOULA, Mont. -

State wildlife officials say seven bighorn sheep have been killed on western Montana highways over the past week.
    
Fish, Wildlife and Parks officials said Thursday that five bighorns were killed along Montana Highway 200 east of Bonner, one in Lower Rock Creek and one on U.S. Highway 93 near the East Fork of the Bitterroot River.
    
No people were reported injured.
    
Wildlife biologist Vickie Edwards says several roadways cross through bighorn sheep habitat and the sheep are attracted to roadways for salt. They also are attracted to irrigated pastures and lawns for green vegetation.
    
FWP urges motorists traveling through areas with bighorn sheep to anticipate sheep merging onto roadways without warning. Edwards says the animals are not always wary of traffic.
