Today we awoke along the riverbank of the Rio Ucayali, one of the main tributaries of the Amazon River. After a delicious and colorful breakfast, we set out for our first adventure in the small skiffs to look for wildlife in Clavero Lake. We were immediately greeted by fishing river dolphins, pink and gray, making for a great start to the day. Our morning brought us countless bird species, a pygmy marmoset, and long-nosed bats. Back on board the Delfin II, we enjoyed presentations about the natural history of the area and photography in the jungle before setting out in the late afternoon in the skiffs again. This time, we explored the narrow passageways of Supay Caño, seeing many local fishermen in small canoes along the way. We were greeted with more birds, a sloth, and another pygmy marmoset! It was a great start to our week exploring Pacaya Samiria National Reserve.
