DNR revises moose study after finding high rates of abandoned calves

Moose calf
A moose calf less than a week old sits with newly applied deer tags and a GPS collar in northeast Minnesota. The Minnesota Department of Natural Resources is placing the collars on 50 moose calves this month as part of a study to determine what's caused the moose population in the Arrowhead region to plummet by two-thirds since 2006 to fewer than 3,000 animals in 2013.
