In Zimbabwe, I am indebted to subscriber Michael Hamrick for a fascinating note about the use of a North American-type predator call on African game. He mentions this in a report he filed on a lion hunt this past August near Gona-Re-Zhou National Park with Lowveld Hunters. He writes: "Lion were scarce in the area and we weren't able to call one in. But, believe, me - predator-call hunting in Africa is exciting. We called in civet, jackal, leopard and numerous hyena. We were actually rushed by an entire pack of hyena that came to within point-blank range. By all means, if you try this in Africa, be sure you use a remotely operated tape player. Place it 50 to 75 feet away from you to avoid dangerous confrontations. I guarantee you moments of extreme adrenaline rush," he writes. Has anyone else heard of this in Africa? Does it raise ethical issues? Are predator calls the answer to hyena overpopulation in some areas? We are eager to get more feedback.
