Our expedition started in great form, with an early outing before breakfast followed by another right afterwards, and many of us took the option to go kayaking. When in the rainforest or the tropics in general, it is always rewarding to go out with the first light, and today was no exception as the many sightings in our lists demonstrate. In the afternoon we hiked across primeval forest to the hanging bridges of the Amazon National Park. From there, we accessed a different perspective of the forest, that of the many organisms that live in the canopy area. Sailing into the sunset, we continued exploring the Marañón River for the remainder of the day.

Delfin II
Ucayali River and Dorado River
Today we had the opportunity to explore the riverbank of the Ucayali River. The exploration was done early, before breakfast. Different species of birds were sighted. It was a great morning for observing the behaviors of the early birds. After breakfast we hiked through the Illanalpa flooded forest. Here we learned about the strategies that animal and plants must have in order to survive the floods. We encountered troops of common squirrel monkeys and saddle back tamarins. Interesting insects were also seen through the leave litters. Back on board we repositioned Delfin II for our late afternoon exploration of Dorado River. We went to explore just before sunset. A family of Isabel’s saki monkey were seen way up in the canopy. A small troop of brown capuchins together with the common squirrel monkeys were moving alongside the riverbank, having their meals before gathering for the night. As the sun began to set, we started to look for caimans. We learned the difference between the black caimans and the spectacle caimans. The highlight was a small family of capybaras walking along the riverbank, not caring at all about our presence. It was the best ending for our explorations today.
