Andean Puma
The Andean puma, also known as the mountain lion, is the fiercest feline of the Andes and one of the top predators in South America. This feline in South America has a coat ranging from black to brown, adapted to the changing climates of the Andes.
Pumas typically inhabit rocky and grassy slopes, where they forage and feed on raccoons and deer. Although extremely elusive, they live in the remote mountain valleys of the Machu Picchu Inca Trail area. Encounters are very rare, as they avoid humans.
Andean Condor
It has the scientific name of Vultur gryphus, it is one of the most impressive and largest birds in all of South America. Males can reach a wingspan of up to 3 meters and weigh between 11 and 15 kilograms, while females are slightly smaller. They are characterized by having a long neck and a bare head with rough, wrinkled skin that is pink to red. Its natural habitat is the Andes Mountain range (mountains of Peru, Ecuador, Bolivia, Colombia, Chile, Venezuela and Argentina), it is a scavenger bird.
It is characterized by its large size, black wings and its great sense of smell and sight. It is not very common to see condors on the Inca Trail, although it is possible, especially on the first day of the trip. Historically revered in many Andean cultures as it is a symbol of power and freedom, the Andean condor unfortunately faces threats due to hunting, habitat loss and accidental poisoning from the consumption of poisoned bait intended for other species and is listed as «near threatened» on the IUCN Red List.
The Taruka or Andean Deer
It has the scientific name of Hippocamelus antisensis, it is a species that is in danger of extinction due to indiscriminate hunting, this animal lives in the Andean forests, it moves from 1,500 meters above sea level to 3,200 meters. It is a slender animal that can reach 80 centimeters in height and has short fur and small horns, known for its agility, it uses its hooves to climb through the Andean forests.
They are animals that are shy around people and very cautious, generally avoiding the proximity of humans and if they feel threatened, they quickly flee. They can live up to 14 years, the human presence and the loss of their natural habitat have endangered this species. During the Inca Trail, especially in the last days of the walk, it is possible to see them hidden in the forests. This animal is the symbol of the fragility of the Andean ecosystem, and its sighting is a reminder of the importance of protecting the species that still inhabit these territories.
Cock-of-the-Rock
It has the scientific name of Rupicola peruviana, also known as tunki or tunqui, it is one of the most emblematic birds of South America, it lives especially in the tropical forests of the Andes and is a symbol of Andean biodiversity. The cock-of-the-rock is frequently seen on the route of Aguas Calientes and the Mandor waterfalls. It measures approximately 32 centimeters long, the male has very bright colors between red, orange and black, while the female is only gray.
It is a solitary and silent bird, something very curious is that during the mating season around 50 males gather on the rocks to be chosen by the female, these rituals are one of the most impressive sights of the Andean fauna. During the Inca Trail, it is possible to observe them in the last and penultimate days on the cliffs of the mountains hidden among the vegetation. The cock-of-the-rock is one of the most sought-after species by bird watchers and is one of the jewels of biodiversity that lives in the Historic Sanctuary of Machu Picchu and its surroundings, which is why the protection of its habitat is crucial.
Royal Cinclodes
It has the scientific name of Cinclodes aricomae, it is an endemic bird of Peru which lives in the Polylepis forests on the slopes of tropical forests and mountainous regions of Peru and Bolivia,. This bird prefers mountainous regions of 3,500 to 4,800 meters above sea level which makes it a species that adapts to the cold environments of the Andes. It is brown and has white spots on its eyes. This characteristic distinguishes it from mountain birds, as it gives it a unique appearance.
IIt measures approximately 22 centimeters and is in critical danger of extinction, as its population is small, as well as because its habitat has a limited extension and the extinction of polylepis, which are essential for its survival. Although it is difficult to spot, this bird is frequently seen along the Inca Trail and throughout the Historic Sanctuary of Machu Picchu. The conservation of this bird is important, as it is an indicator of the environmental health of the Andean mountains.
The Torrent Duck
It has the scientific name of Merganetta armata, it is a species of aquatic bird that lives in fast and cold rivers of the Andes. Torrent ducks are medium-sized, with an average length of about 40 to 45 cm. They have distinctive and striking plumage, their head is iridescent green, with a long, pointed crest in males.
The body is mainly reddish brown, with white spots, while females have duller and less bright plumage than males. During the Inca Trail, it is possible to observe them from a distance over the waters of the Vilcanota River, especially in January, February or March, when they can be seen swimming or resting on the banks of the rocks. The conservation of these species is vital to maintain the balance of the ecosystems surrounding the Inca Trail and the historic sanctuary of Machu Picchu.
The Andean Squirrel
It has the scientific name of Bothrops andianus. It is an endemic species of poisonous snake. Adults normally measure between 60 and 70 centimeters. It lives in the tropical mountainous regions of Cusco and Puno in Peru. It prefers habitats between 1,800 and 3,300 meters above sea level. They have a brown and leaden color that camouflages them easily. However, they do not usually crawl along the paths of the Inca Trail, but they do crawl in the forests restricted to visitors. If you come across one, it is best not to disturb it and simply follow the path.
Andean Frog
It has the scientific name of Telmatobius, a genus of amphibians that includes more than 64 species, many of which are endemic to the Andes. These aquatic frogs are usually small, measuring 53 to 67 millimeters, and are easily recognized by their orange or brownish coloration, which helps them blend into the mossy streams and wetlands they inhabit. They live in swamps, springs, rivers, and mountain streams, preferring clean, oxygen-rich waters at high altitudes.
In the Sanctuary of Machu Picchu, several species of Andean frogs can be found, many of which are threatened or endangered due to habitat loss, pollution, and climate change. Their presence is a key indicator of ecosystem health, as they are highly sensitive to environmental changes.
Along the Inca Trail, hikers can observe these frogs in their natural habitat, particularly in streams and small ponds during the rainy season, mainly in January, February, and March. They are more active during this time, often seen near moss-covered rocks and flowing water.
These amphibians play a crucial role in the Andean ecosystem. They help control insect populations and serve as a food source for larger animals, including birds, snakes, and small mammals. Conservation efforts focus on protecting their habitats, monitoring populations, and raising awareness about the fragility of high-altitude aquatic ecosystems.
The Andean frog also has cultural significance for local communities, who have long recognized amphibians as part of the natural balance of the Andes. Ecotourism along the Inca Trail provides an opportunity for visitors to learn about these unique creatures while supporting conservation initiatives that help protect both the wildlife of the Inca Trail and the fragile watersheds they depend on.
