Shortly after the 4 month old pup howled I heard rustling in the bushes just ahead of me. Peering up the avalanche chute, through all the bent aspen saplings I spotted the movements of another wolf. As it entered a clearing it was clear that it was the mother. She was making her way through the trees  carrying the back end of a lamb in her mouth! She made her way to the pup hiding in the forest and shortly afterwards I heard the excited cries of the reunion and then growls over the meat. If you look closely you can see the hooves of the lamb near the base of the radio-collar.  Survival of the fittest in its purest form.
