A Florida chimpanzee sanctuary briefly had to deliver food to one of its 200 apes by drone this week because the property was swamped by heavy rain. But Save the Chimps says the animals stayed safe. By Saturday, the water finally was receding significantly. Rainstorms soaked southeast and central Florida from Sunday through Tuesday. Save the Chimps is near Fort Pierce. The organization says the animals' care houses were secure on high ground, but canals overflowed and submerged the internal roads that staffers normally use to deliver food to the apes by golf cart. Save the Chimps bought a delivery drone some time ago for just such an emergency.
