Fauna of Machu Picchu: Birds, Viscachas, Vicuñas, and the Animals That Share the Citadel

Machu Picchu is not just an archaeological site. It is also a living ecosystem in which wildlife is not a decorative element or an accident of the landscape: it is a constitutive part of the place, and in some cases it has lived alongside visitors for so long that it has lost much of its distrust of human beings. The viscachas sunning themselves on the stone terraces, the hummingbirds moving among the flowers along the walls, and the condor that on favorable days glides over the Urubamba Canyon without seeming disturbed by anything happening below are, for many visitors, moments just as memorable as the view of the citadel from the Guardian’s House lookout.

The Historic Sanctuary of Machu Picchu has recorded more than 420 species of birds, dozens of species of mammals, amphibians, and reptiles, and a diversity of insects that entomologists are still cataloging. This post focuses on the animals most easily seen during a standard visit to the citadel and on the conditions that favor those sightings, while also mentioning the most notable species that inhabit the sanctuary even if they are not visible from the tourist trails.

Viscachas: the Most Visible Residents of the Citadel

If there is one animal that visitors directly associate with Machu Picchu, it is the viscacha. This Andean rodent, which belongs to the chinchilla family and looks like a mix of rabbit, squirrel, and chinchilla, lives in the cracks and gaps between the rocks of the terraces and walls of the archaeological site, and over generations has developed a tolerance toward humans that makes it the easiest animal in the entire citadel to photograph.

The mountain viscacha (Lagidium viscacia) is the species found at Machu Picchu. It has a sturdy body between 30 and 45 centimeters long, covered in grayish-brown fur that camouflages it almost perfectly against the granite rocks of the terraces, and a long, furry tail that it curls over its back when resting. Its long ears, large eyes, and upright posture when alert give it an appearance that many visitors describe as a rabbit disguised as a squirrel.

The best time to see them is early in the morning, between 6:00 and 9:00 a.m., when viscachas come out of their shelters in the rock crevices to sun themselves on the terraces. During those first hours of the day they are very active and relatively trusting: it is common to see groups of two or three individuals just a few meters from the main trail, apparently unbothered by the presence of visitors. At midday, with the sun high and the site more crowded, they tend to retreat to the less trafficked areas of the agricultural sector and the enclosures at the northern end of the citadel.

Viscachas are considered a non-threatened species in Peru, but within the sanctuary they are protected under the general regulations that prohibit disturbing, feeding, or capturing wildlife. Feeding them something some visitors try to do with snack leftovers is a practice that alters their natural feeding behavior and can cause digestive problems, in addition to being a violation of site regulations.

Birds of the Sanctuary: 420 Species in a Single Territory

The Historic Sanctuary of Machu Picchu has between 420 and 430 recorded bird species, representing approximately 40 percent of all bird species known in Peru and around 5 percent of all bird species in the world, in an area of less than 33,000 hectares. This concentration of bird diversity is the direct result of the sanctuary’s altitudinal gradient, which ranges from the low tropical forests of the canyon to the puna above 4,000 meters, and of the variety of habitats available within that elevation range.

For visitors who are not specialized birdwatchers, the species easiest to see in the citadel and its immediate surroundings are also some of the most striking in the sanctuary. You do not need to be an ornithologist to stop in your tracks at the sight of a long-tailed hummingbird or a cock-of-the-rock perched on a branch just two meters from the trail.

The Cock-of-the-Rock: Peru’s National Bird at Machu Picchu

The Andean cock-of-the-rock (Rupicola peruvianus) is Peru’s national bird and one of the most spectacular animals that can be seen in the Machu Picchu area. The adult male has bright orange plumage covering the head, chest, and back, with black and gray wings that contrast sharply with that orange color. On its head it has a permanent semicircular crest that covers part of its bill. It is a bird that, once seen, is impossible to confuse with any other species.

The cock-of-the-rock inhabits humid mountain forests between 1,000 and 2,400 meters in elevation, and the Machu Picchu area falls within that range. The most frequent sightings occur on the forested slopes below the citadel, especially along the hiking route from Aguas Calientes, on the trail descending toward the Urubamba River, and on the slopes of Putucusi. It has also been seen along the forest edges in the northern sector of the archaeological site, near the Sacred Rock.

Male cock-of-the-rocks perform elaborate courtship displays in spaces called leks, where several individuals gather and show off their plumage to females. These leks are located at fixed points in the forest that the males use year after year, and local guides who know their location can take visitors interested in birdwatching to observe this behavior, which is one of the most remarkable natural spectacles in the Andean region.

Hummingbirds: the Pollinators of the Cloud Forest

Hummingbirds are the most active animals and the most constantly present in the visual landscape of Machu Picchu. The sanctuary has recorded more than twenty species of hummingbirds, a number that reflects both the diversity of the ecosystem and the abundance of flowering plants adapted to pollination by these birds. At any time of year, in any part of the site where flowers are blooming, there is some species of hummingbird moving among them.

The most common species in the immediate surroundings of the citadel include the giant hummingbird (Patagona gigas), the largest in the world at up to 21 centimeters in length, which frequents open areas and the higher slopes of the sanctuary; the long-tailed hummingbird or marvelous spatuletail (Loddigesia mirabilis), a species endemic to northern Peru that is occasionally recorded in the area, whose male has two tail feathers ending in discs that are among the most elaborate ornaments in the animal kingdom; and several species of the genera Metallura and Aglaeactis, medium-sized hummingbirds with iridescent plumage that in males changes color depending on the angle of the light.

The hummingbirds of the citadel are completely indifferent to human presence as long as visitors do not make sudden movements. It is common to see an individual feeding on flowers growing along the edges of walls or on trailside plants less than a meter from passing hikers. That proximity, combined with the speed of their movements and the characteristic hum of their wings which in some species reaches 80 beats per second makes watching them an experience that requires neither specialized equipment nor exceptional patience.

The Andean Condor: Master of the Urubamba Canyon

The Andean condor (Vultur gryphus) is the largest flying bird in the world, with a wingspan that in adults can exceed three meters. It is not a regular resident of the immediate Machu Picchu area its range extends across hundreds of kilometers but the Urubamba Canyon is one of the flight routes it uses regularly, and sightings from the citadel, from Huayna Picchu, or from Machu Picchu Mountain are frequent enough that many visitors see it during their visit without having planned for it.

The condor uses the warm air currents rising from the bottom of the canyon to glide effortlessly for hours, covering great distances without flapping its wings. From the terraces of the citadel or from the summit of Huayna Picchu, seeing an adult condor soaring above the Urubamba River at the same height or even below the observation point is an experience no visitor forgets. The featherless red head of the adult, the white collar around the neck, and the disproportionate size of the bird in flight are unmistakable even for someone with no prior bird identification experience.

Sightings are more frequent in the early morning, when warm air currents begin to form over the canyon, and on days when the sky is partly clear with wind coming from the east. Guides experienced in wildlife spotting at the site usually know which observation points offer the highest probability of sightings under each weather condition.

The Mountain Toucan and Other Forest Birds

The sanctuary’s bird diversity goes far beyond the best-known species. The Andean toucan or mountain toucan (Aulacorhynchus prasinus) is one of the most striking: a bird about 35 centimeters long with entirely green plumage and a disproportionately large bill in shades of green, yellow, and black that frequents the canopy of the cloud forest between 1,800 and 2,800 meters. Its call a series of hoarse, repetitive notes is one of the most common sounds of the cloud forest at Machu Picchu, although the bird itself can be difficult to locate among the foliage.

The masked trogon (Trogon personatus) is another species that appears relatively frequently in the sanctuary’s forest. The male has a bright red chest, metallic green back, and a black mask around the eyes that gives it its name. Like all trogons, it has the habit of remaining motionless on the same branch for extended periods, which makes it difficult to detect but relatively easy to observe once found.

Tanagers, represented in the sanctuary by several dozen species, are the most colorful birds of the cloud forest in terms of sheer color density: combinations of electric blue, red, orange, black, and yellow that in some cases seem almost unreal to anyone used to the more subdued palette of birds from temperate latitudes. The multicolored tanager (Chlorochrysa nitidissima) and paradise tanager (Tangara chilensis) are two of the species most frequently recorded in sanctuary birding lists.

Mammals of the Sanctuary: the Ones You See and the Ones You Sense

The mammal diversity of the Historic Sanctuary of Machu Picchu is remarkable but much less visible than its birdlife. Most of the sanctuary’s mammals are nocturnal or crepuscular and live in areas far from the tourist trails, which makes sightings from the citadel or the main paths sporadic and highly dependent on luck.

The spectacled bear (Tremarctos ornatus) also called the Andean bear or ukuku is the only bear in South America and one of the sanctuary’s emblematic species. It inhabits forested areas between 1,900 and 3,500 meters in elevation, with a mainly vegetarian diet that includes fruits, shoots, tubers, and to a lesser extent small animals. Its presence in the sanctuary has been documented by camera traps in areas farther from the tourist trails, and sightings from the authorized paths are extremely rare. It is, however, a real and constant presence in the sanctuary ecosystem, and its conservation is one of the priority goals of the protected area’s management plan.

The puma (Puma concolor) also has documented records in the sanctuary, although with a very low population density given the size of the territory and the level of human disturbance in accessible areas. Tracks footprints, tree markings, prey remains are the most common evidence of its presence. A direct sighting from the tourist trails is practically exceptional.

The mountain tapir (Tapirus pinchaque) is perhaps the sanctuary’s most surprising mammal in terms of the contrast between its size it can exceed 200 kilograms and its ability to go unnoticed in the forest. Its nocturnal habits and preference for dense vegetation make it one of the hardest animals to see in the sanctuary despite its size. It is also one of the most threatened species: it is classified as vulnerable on the IUCN Red List, and the Machu Picchu sanctuary is one of the few protected territories in the Andes where its population remains stable.

Llamas in the Citadel: Domesticated and Functional

The llamas grazing on the terraces of Machu Picchu are not wild fauna: they are domesticated animals introduced to the site by the Ministry of Culture as part of the agricultural terrace maintenance program. Their function is practical llama grazing helps keep the grass short on the terraces without the need for machinery that could damage the underlying archaeological structures but their visual effect is also to restore to the site an animal presence that was a constitutive part of daily life in the Inca citadel, where llamas were pack animals, a source of fiber, and key participants in the most important ritual sacrifices of the calendar.

The llamas of Machu Picchu are used to human presence and are generally calm around visitors who keep a respectful distance. The recommended distance for photographing them without causing disturbance is at least two meters: llamas that feel cornered or invaded in their space may spit, a defense that can unpleasantly surprise anyone not expecting it. With the proper distance, they are one of the most photogenic subjects at the site, especially in the early morning when side light illuminates the terraces from the east.

How to Maximize Wildlife Sightings During Your Visit

Your arrival time at the site is the factor that most influences the quality of wildlife sightings. The first two hours after opening between 6:00 and 8:00 a.m. are the period of greatest animal activity in the citadel and its surroundings: viscachas are sunning themselves, hummingbirds are actively moving among the flowers, forest birds are calling from the site’s edges, and llamas are grazing on the terraces without the disturbance of tour groups that arrive later. The same archaeological site that at 10:00 a.m. is full of visitors has at 6:30 a.m. a stillness that favors observation of everything that is not stone.

Moving slowly is the second most important recommendation. Groups that move quickly through the circuit with a guide create a level of disturbance that causes more sensitive animals to retreat before they can be seen. Visitors who walk alone or in small groups, who stop frequently, and who do not make loud noises have a radically different wildlife experience from someone who moves through the site at the pace of a two-hour tour.

Bringing lightweight binoculars even a compact 8×25 model transforms the site’s birdwatching experience. Many of the most striking cloud forest birds move at distances that make it difficult to appreciate plumage detail with the naked eye, and binoculars turn a patch of color in the foliage into an identifiable species with recognizable characteristics. For visitors with a specific interest in birdwatching, hiring a certified birding guide and Aguas Calientes has several is the option that makes the greatest difference in the number of species seen and the quality of sightings.

The wildlife of Machu Picchu is not separate from the archaeological experience: it is part of it. The viscachas resting on the same walls built by the Incas, the condor gliding over the same canyon that priests once observed from the temples, and the llamas grazing on the same terraces where corn grew five hundred years ago are reminders that Machu Picchu is not a site frozen in the past, but a living ecosystem in which history and nature continue to share the same space.
