Entertained by the cries of howling monkeys and shrieking parrots, we were all stunned to silence by a loud roar.
Suddenly, the rain forest around us was quiet.
Our guide reassured us. "All is well," he said. "It's unusual to hear a jaguar during the day, but he's about five miles away."
But the jungle remained quiet.
"We'll just stay here for a while," our guide said.
Very slowly, the sounds of the jungle around us resumed. We were quite happy to stand at the top of this old Mayan pyramid, peering out into the underbrush that covered the ground, and wondering if we would catch a glimpse of this amazing and feared predator.
