HOUGHTON, MI-- Wolf pups have been born on Isle Royale National Park for the first time since 2014.
Officials from the park and the State University of New York documented the arrival of at least two pups in 2019 and two litters of an unknown number of pups this year.
Seven wolves were relocated from an Ontario island and the mainland to Isle Royale in 2019. One of the females was likely pregnant. This year’s pups were bred on the island.
