Authorities are investigating the deaths of two cows – one a calf – on a wildlife refuge in Minnesota.
Sherburne County Sheriff's Office said the two animals were found dead near 293rd Avenue Northwest in Blue Hill Township on Tuesday.
They were discovered on land within the Sherburne National Wildlife Refuge by the cows' owner, who said his cattle graze on the refuge.
Judging by their decomposition, they are likely to have been dead for several days.
The cow was in a creek and the calf was found about 15 feet away, a quarter mile north of the Blue Hill Cemetery.
Anyone with information about the incident should call the sheriff's department at 763-765-3500.
The Sherburne National Wildlife Refuge is run by the federal U.S. Fish and Wildlife Service, having been established in 1965 to promote the health of migratory birds and their habitat.
It is a mixture of grasslands, oak savanna and forest, interspersed with wetlands, river habitats and marshes.
