Wolves recently relocated to the Isle Royale National Park seem to be finding enough to eat.
Scientists who have been observing the wolves released an update yesterday.
More than half of the prey eaten by the wolves have been moose. One of the reasons for rebuilding the wolf pack on the island is to control the moose population, which had exploded as the pack was nearly wiped out by health problems caused by inbreeding.
The new wolves have also dined on hares and beavers.
There are now 17 wolves on Isle Royale. Their movements are monitored by radio collars. Officials hope to stabilize the pack at 20 to 30 with some additional relocations next year.
The summer study was conducted by the National Park Service and the State University of New York – College of Environmental Science and Forestry.
