After two years of struggling to study moose calves, Minnesota wildlife researchers plan to give the moose calves study another try this year after working out a few issues. Last summer, researchers collared 25 calves to determine the cause of die-offs, but most of them were abandoned by their mothers and had to be rescued, or their collars fell off. The remaining calves were eaten by wolves. This year, researchers plan to study why the Minnesota moose population is dwindling by capturing a larger sample size and tracking the calves’ early years of life.
