On the river bank watching the caiman activity. Jaguars like water; they hunt in it, swim in it, fish in it and even play in it. I have read that there are stories that people have seen jaguars dangle their tails in the water to catch fish. The word Jaguar comes from the Indian Yaguar which means "he who kills with one leap". They have the strongest jaws of any of the big cats, 2,000 lbs of force.
Coming down to the water for a possible attempt on a caiman. These powerful cats are drawn to the river for their food during the Brazilian winter, or dry season. Very late afternoon or early evening, the sun begins to sink and the air cools, this is when the cats show interest any interest in moving. This is the only extant panthera species native to the Americas. It is the third largest of the big cats.
No more sun, this cat took a moment to sniff the greenery. No matter the size of the cat, you will see cat positions and activities that are similar to your house "panther".
