These elusive cats rank among Latin America’s supreme predators. Conservationists seek to connect their isolated refuges.



Get a taste of what awaits you in print from this compelling excerpt.

Poking along the road one day, we intercepted a giant anteater and several crab-eating foxes. Giant river otters barked when they spied us from the Cuiabá River. Howler monkeys reacted to Fião’s calls with roars of their own. But a mother jaguar and cub crossing far ahead of the ranch truck provided only the briefest glimpse of our quarry. Darkness was flooding out the last of an orchid sky when Fião pointed far down the road and whispered “Onça”—jaguar, in Portuguese. Steve Winter checked his cameras, then the cat, and announced, “It’s Bob.”

We had met the same jaguar lounging on the road the evening before, and it reminded someone in our crew of a burly, big-headed, rather unmotivated relative named Roberto. Now Almeida, Winter, and I crouched at the road’s edge behind overhanging brush while onça Bob padded on, unaware or unconcerned that he was less than 100 yards (91 meters) from us, 80 yards (73 meters), 50 yards (46 meters). Pairs of tree-perching waterbirds known as southern screamers noisily marked the jaguar’s progress, a habit that has earned them the alternate title of Pantanal guards. We kept as motionless as sunbathing caimans, though it occurred to me that in parts of the Pantanal those slender crocodiles are jaguars’ principal prey. Don’t bother with me, Bob, I thought, glancing at the mosquitoes coating every inch of my skin, you won’t find any blood left.

At a distance of around 20 yards (18 meters) he paused to stare. All at once, this was no longer Bob or anything else except a massive, intelligent feline met deep in its homeland and taking our full measure. Winter began snapping pictures, flash attachment firing apace. The animal’s only reaction was to slowly turn and amble across the roadway. It eased off the shoulder and into flooded woods, and we could hear footfalls in the water as the cat continued around us and on into the night. Ten minutes later Almeida was playing a flashlight beam over the brush out of curiosity and caught the twin sparks of jaguar eyes, still measuring. Then there were only fireflies casting their phosphor light among the tangles.

I had been entranced by the sway of the beast’s heavy belly as it approached. This cat was dining well; maybe that was why it seemed so patient with us. Whereas other big cats eat primarily hoofed prey, jaguars also take fish, iguanas, anacondas, turtles, unwary birds, and small mammals from monkeys to rodents. It would almost be easier to list what onça doesn’t eat. Introducing livestock to its range is guaranteed to broaden its diet even further. That evening at the house, while bats harried insects near the ceiling, Joaquim Proença, the ranch manager, told me that jaguars have killed as much as 8 percent of the ranch’s cows in one year at São João. Fião said he and his brother lost almost 10 percent of the cattle on their small ranch to the cats. Like São João’s owners they tolerated the kills as the price of Pantanal ranching, but most stockmen respond with dogs and guns. “We are paid to take good care of the herds,” a cowboy elsewhere told me. “We spend a lot of time fixing calves with maggots or disease. Then one night the calf or its mother is gone. It is a hard thing to accept. Jaguars are very beautiful. If it wasn’t for the cattle killing, I wouldn’t hunt them.” As things stood, he had killed about 70.

Researcher Sandra Cavalcanti from Utah State University studies jaguar activity in relation to ranching practices. At Fazenda Sete, one of three related family estates that jointly encompass 308,000 acres (1250 sq. kilometers) in the southern Pantanal, hyacinth macaws commented loudly from an ipê tree while she tied her horse in its shade. Sniffing the air, she led me through the undergrowth to the flyblown remains of a cow. The animal had been reported as a jaguar kill by the cowboy who found it and noticed fresh cat tracks at the thicket’s edge. His horse was unnerved by the shadows and scents, so he did not linger. Cavalcanti, who generally rides the countryside alone armed with a water bottle and a notebook, did. The cow had died giving birth. Like the cowboy, the passing jaguar had never even gone over for a close inspection.

The World Conservation Union (IUCN), founded in 1948, is a group of scientists, government agencies, and other authorities who work to preserve our planet’s biodiversity. For almost 40 years it has been evaluating the conservation status of plant and animal species around the world. Its experts provide information on taxa that are considered extinct as well as information on the relative risk of extinction for numerous other taxa. They are categorized as to whether they are critically endangered, endangered, vulnerable, or at a lower risk. The 2000 IUCN Red List of Threatened Species documents the status of over 9,000 animals and nearly 7,000 plants. If you would like to find out in what category a species falls, visit the searchable database at www.redlist.org.
