Today we continued exploring the Ucayali River. October is the last of the dry season in the Amazon basin, and the flood season will soon begin. Along the riverbanks, all houses and lodges are built atop wooden pillars; this is to avoid flooding and unwanted visits from animals.
This morning we rode our skiffs to explore the area and we found a few surprises. There is an island where some woolly monkeys live, so we took a short walk to see these incredible primates. We observed them playing up and down along the vines of huge trees and jumping from branch to branch. They are very agile and use their prehensile tail as a fifth extremity to climb the trees. It was a unique and astonishing experience to share their environment for a short time. Farther along the river we found some local fishermen, catching freshwater fish for their own livelihood.
In the afternoon we motored on the Delfin II to Jose de Paranapura, a small village where a colony of Victoria regia, or large lily pads, are found. We walked into the jungle to a pond where we found many of these unique plants growing and flowering. Frogs, spiders, and some birds like to sit on these lily pads because they create food and shelter for both aquatic and non-aquatic wildlife. They float on the top of the water and make the ponds cooler for other species of animals. Lilies produce natural oxygen that allows fish to breathe and beneficial bacteria to thrive.
Later on we navigated to the conjunction of the Marañon and Ucayali Rivers, which is where the Amazon River officially starts. Our captain offered a cocktail to celebrate this event. It’s not every day you have the opportunity to be in one of the largest rivers of our planet, watching an incredible sunset, and relaxing with the delicious Peruvian Pisco sour. Cheers!

Delfin II
Ucayali and Dorado Rivers
Today we had the great opportunity to start exploring the riverbank of the Ucayali River. We loaded the skiffs right after sunrise. As we cruised along the riverbank, different species of birds were seen. A highlight of that early exploration was the sighting of a tayra, a small omnivorous creature in the weasel family, that didn’t stay long in our view. After breakfast, we walked through Yanallpa flooded forest. Here our naturalist explained to us the importance of the floods for the Amazon forest. They also pointed out the effect of climate change over the area and how it has changed the use of the soils after the floods. It was a morning of learning about how the forest has manage to adapt to the seasonal floods and how fish and other animals depends on those events. Our late afternoon activities were held on Dorado River. Our naturalists brought out spotlights after sunset. Black caimans and spectacled caimans were the major attraction for our guests. Other night dwellers were also spotted by our naturalists, such as fishing bats, boat-billed night herons, night jars, and many other animals were seen by our guests. It was another awesome day exploring the Pacaya Samiria National Reserve.
