Jaguars are the largest cat in the Americas but across most of their range they are much harder to see than the big cats of Africa. Only in Brazil's great wetland, the Pantanal, can they easily be observed and photographed. The young adults in this image are brother and sister, known to biologists as George and Patricia. Pantanal jaguars are active during daylight and spend much of their time patrolling, hunting and resting along riverbanks, making photography possible from a boat. Shortly after I made this image, George swam across the river and successfully hunted a capybara. For more jaguars, see my Big Cats Gallery.
