It is estimated that there are more than 400 species of birds in the reserve, with 358 on the reserve bird list as of June 2020. Some of the most endangered birds in Ecuador, such as the critically endangered Black-and-Chestnut Eagle are here, as well as Tanagers, Hawks, Eagles, Parrots, Owls, and Toucans to name but a few. Over a dozen species of hummingbirds whizz around throughout the forest, some only an inch long. The stunning Andean Cock-of-the-Rock, the Toucan Barbet, and the colorful Golden Headed Quetzal make their home here too.
Evidence in the form of scat, tracks, and the occasional sighting provide the assurance that our six species of felines roam their territories here in the reserve. Common names are the Jaguarundi, Margay, Ocelot, Oncilla, Puma, and the western subspecies of Jaguar. In the morning, along with the chorus of birds, you are likely to be woken by the Ecuadorean Mantled Howler Monkey. He is the loudest, so can often be heard, and sometimes seen, in the canopy. The two other primates are the White-Headed Capuchins and the critically endangered Brown-Headed Spider Monkey. The only species of South American bear, the Spectacled Bear, inhabits the higher elevations of the reserve and is seen on occasion.
