Northern pudu
The northern pudu (Pudu mephistophiles, Mapudungun püdü or püdu, , ) is a species of South American deer native to the Andes of Colombia, Venezuela, Peru and Ecuador. It is the world's smallest deer and is classified as Data Deficient in the IUCN Red List. Description
The northern pudu is the smallest species of deer in the world, standing  tall at the shoulder and weighing . The antlers of the northern pudu grow to about  long and curve backward. Its coat tends to be lighter than that of the southern pudu, but the face is darker compared to the coat. Range and habitat
The northern pudu is found at higher altitudes than its sister species, from  above sea level. It has a discontinuous range across the Andes of Colombia, Ecuador, and Peru. It inhabits montane forests, high-elevation elfin forests, and humid alpine páramo grasslands above the tree-line. The Marañón dry forests are a gap in the species' range, separating the Ecuadorian population from the Peruvian population in the Peruvian Yungas south of the Marañón River. References
