Strange, but missing GJFields library for /home/www/elephantvoices.org/plugins/content/autoreadmore/autoreadmore.php

An individual rumble from F1200310 in the following context: Lion stalks Amy's 2003 calf who looks unwell; Mother Amy is facing into the palms about 5 m beyond her infant; A second adult female, Alison, is also within 5 m around a palm. The lion pounces on the calf who screams; The females respond with 9 minutes of rumbling which keeps the lion at bay and calls in more distant family members as reinforcements.
