Wolves show great interest in lairs – those periodically empty or already abandoned by bears after the lairing period. During the monitoring of the winter dens’ usage, I was able to observe twice the use of bear lairs by wolves as a dry and safe hideaway for their offspring. I found week-old wolves in the lair for the first time on May 8, 2017. I left this place quickly without touching anything – it was also impossible to record the event. This year, in another lair where at some point the bear took the cubs out, 1-month-old wolves brought by she-wolf were accidentally recorded. You can watch it on the video material.
