Bighorn Sheep Pneumonia May Be From Smoke

“Another pneumonia outbreak has killed bighorn sheep in the Skalkaho area, and a veterinarian thinks smoke from wildfires may be to blame,” says an article in the Montana newspaper the Ravalli Republic. “If it spreads, the outbreak would be the 7th major die-off of bighorn sheep in western Montana since 2009.”

Bighorn sheep use overpass

Bighorn sheep have already been photographed using a wildlife highway overpass in Arizona, south of Hoover Dam. The overpasses were completed in January.

Arizona Game and Fish officials were concerned when they heard that Highway 93, in northwest Arizona, was going to be widened. The area is home to the nation’s largest contiguous population of bighorn sheep. Experience had shown that big horn sheep are wary of wildlife underpasses, which are much more popular with the sheep’s predators. Since bighorn sheep like to stay high, and were approaching the highway from the ridgelines anyway, four overpasses were incorporated into the 15-mile-long highway expansion project.
