A mother hyena will do anything to protect her babies -- even, in this case, when she's fighting for her own life.
A pregnant brown hyena was walking along the Savé River in Zimbabwe when she became caught in a hunting snare set by poachers. Reacting to the trauma, the hyena delivered three cubs on the spot -- but she was still stuck (it's worth noting that hyena birth is notoriously painful, and many mothers don't even make it through the experience).
Despite fighting for her own life, the mother's instinct was still to protect her babies, so she dug a small den under herself to keep them safe. This was when rescuers from the African Wildlife Conservation Fund came across her, having been tipped off of a wounded hyena in the area. They darted her with a tranquilizer and approached to find a surprise -- two cubs squirming around in the dirt, just a few days old (sadly, one of the cubs had died before they arrived).
