Authorities say three Michigan duck hunters ended up wounded following a mishap involving another hunter.

MLive.com reports the men were among a group of four hunting Saturday in Lapeer County's Burnside Township about 55 miles north of Detroit.

The sheriff's department says the three were leaving when the fourth hunter took a shot at a duck, hitting the three men with birdshot.

Authorities say the men ages 42, 59 and 65 were treated at a hospital and released.

No charges are expected.

The sheriff's department says the men who were shot were all wearing camouflage and the 43-year-old shooter didn't see them.
