We reached the farthest point along the Ucayali River. Early in the morning, we explored the Pacaya River in search of the elusive red howler monkey and many birds. We also went for the famous Amazon plunge in a black water lagoon. It was a really fun morning.
In the afternoon, we explored Zapote River. We observed many birds and a very special species of monkey, the monk saki monkey; this was very unexpected and wonderful.
