The jaguar or panthera onca has to be one of the most magnificent animals on Earth. Maybe the most magnificent. Only the tiger and lion are larger cats. Our Maya friend Aniceto says we have a jaguar den on our ranch; probably some shallow limestone cave covered by dense growth. Part of our ranch is virgin rainforest.

We’ve never seen our jaguar but he has. One evening coming back from his “milpa” he saw it in the middle of the road. Usually they don’t come out at all when it is light, but this one did. The jaguar or “el tigre” as he is called by the Maya, probably was hungry and looking for a tepe, tejon or javalina. Humans eat the same food, though we barbecue tepe and the jaguar chomps it down raw.

Polychlorinated biphenyls (PCBs) are mixtures of up to 209 individual chlorinated compounds (known as congeners). There are no known natural sources of PCBs since PCBs are no longer produced in the United States, but they are still found in the environment. PCBs are either oily liquids or solids that are colorless to light. Some PCBs can exist as a vapor in air. PCBs have no known smell or taste. Many commercial PCB mixtures are known in the U.S. by the trade name Aroclor. PCBs have been used as coolants and lubricants in transformers, capacitors and other electrical equipment because they don’t burn easily and are good insulators.
