Sciurus pyrrhinus O. Thomas, 1898 is a rodent commonly called the Juńın red squirrel or ardilla rojiza. This large-bodied, arboreal species is characterized by a rufous dorsum and an orange tail, and is 1 of 28 species in the genus Sciurus. Endemic to Peru, S. pyrrhinus is found on the eastern slopes of the Andes between 600 and 1,500 m above sea level, spanning rain forest and montane forest habitat. Described as common within its limited distribution, the Peruvian Ministry of the Environment classifies S. pyrrhinus as ‘‘Vulnerable’’ and the International Union for Conservation of Nature and Natural Resources considers it ‘‘Data Deficient.’’

Microsciurus flaviventer (Gray, 1867) is a Neotropical tree squirrel commonly known as the Amazon dwarf squirrel. Small bodied with dark brown dorsal pelage contrasted with a gray or yellowish gray venter, and a faintly banded tail. M. flaviventer is 1 of 4 species in the genus Microsciurus. The geographic range of M. flaviventer extends from the Amazon basin of South America throughout western and southeastern Colombia, Ecuador, southern Peru, Brazil west of Río Negro, and Madeira. It is most commonly associated with evergreen lowland tropical rainforest. Status of M. flaviventer is “Data Deficient” under the International Union for Conservation of Nature and Natural Resources Red List of Threatened Species; however, loss of habitat is a major concern.
