The chimpanzees’ open-top outdoor enclosure always changes a bit overnight. We do a daily morning check to make sure nothing has dramatically changed (like a broken fence wire) or a stray animal who can’t quite find their way out, but there are inevitably little changes that occur each day. This morning the sanctuary was cool and calm. The chimpanzees were eager to eat their breakfast that was being served in the greenhouse. Then through all the peace, came a noisy rustle in the brush above Young’s Hill. Having already done my perimeter check of the fence line, I knew that our neighbor’s horses were grazing the top pastures and consequently making a bit of commotion. The chimps needed to see the cause of the disturbance for themselves, so upon receiving access to their outdoor enclosure, all of them (minus Negra) raced up the hill to investigate.
