While the diversity of birds we found today in the Pacaya-Samiria National Reserve numbered nearly 50, they were not the only highlight. We covered the reptiles with our spotting of a rosy-tailed boa wrapped up high on a tree limb. Mammal sightings were incredibly diverse, from pink and gray river dolphins to squirrel and red-bellied titi monkeys, a couple of brown-throated three-toed sloths, and a line of seven long-nosed bats doing their best impression of tree bark. Whew! A lovely, exhausting day of sightings as we explore the Upper Peruvian Amazon.
