Exploring the Dorado and Zapote Rivers

Our wake up call came a bit early this morning as a fierce thunderstorm lit up the sky and rattled us awake. The rain slowed to a drizzle and we set out to explore the Rio Dorado. Some explored by skiff while others again took to the kayaks. Small side channels filled with floating vegetation were the perfect place to sneak up on wildlife. Kingfishers were abundant and some kayakers got very close to the amazing Pygmy Kingfisher. A few sloths were spotted and quite a few monkeys, including two groups of Brown Capuchins.

Returning to Delfin II for breakfast we enjoyed the “dolphin show.” Both Gray and Pink River Dolphins were feeding all around the ship. As we continued cruising up the Ucayali River, more sloths were spotted in the trees, and as the rain ended, birds became very active. Massive flocks of parakeets swirled around, and many hawks and vultures lifted off. The Ucayali River is rising, and some of us watched a pretty large bank collapse. Quite a few trees toppled over, entering the river as it continues to alter its course.

After the rain, the afternoon skiff rides up the Rio Zapote were filled with activity. Two Red-and-green Macaws were stunning in the afternoon light. Many sloths were also drying off and some Green Iguanas were basking. Large groups of squirrel monkeys and a few Monk Saki added to a wide variety of birds.

As it got dark, we listened as the night shift came on duty. Clouds of bats passed overhead, probably exiting from a nearby large hollow tree. We made our way back in the dark, searching for nocturnal critters. The eye-shine of a caiman drew our attention and we approached for close views. Satellites passed overhead and the moons of Jupiter were enjoyed. A few nocturnal birds were also spotted including a potoo, Common Pauraque, and many Boat-billed Herons.

During dinner we continued farther up the Ucayali River to arrive at tomorrow’s destination at the Pacaya River, where we hope to continue our diversity of wildlife sightings.
