Andean condor. The Andean condor (*Vultur gryphus*) is a massive South American bird in the New World vulture family Cathartidae. It is the largest flying bird in the world by combined measurement of wingspan and weight, serving as a significant national symbol for several Andean countries and playing a vital role in local folklore and ecology as a scavenger.

Description and taxonomy

The species was formally described by Carl Linnaeus in the 1758 edition of his Systema Naturae. It is the only accepted living member of the genus *Vultur*, distinguished within Cathartidae by its immense size and pronounced sexual dimorphism. Adults possess a distinctive featherless head, which can flush red during periods of emotional excitement, and a broad white ruff of feathers at the base of the neck. The plumage is primarily black with striking white patches on the upper wing coverts, a feature more prominent in males. The male is larger and has a large, dark caruncle and comb, absent in the female. Its taxonomy has been debated, with some studies suggesting a closer relationship to storks rather than to other birds of prey like eagles and hawks.

Distribution and habitat

The Andean condor is found along the entire spine of the Andes mountain range, from Venezuela and Colombia in the north, through Ecuador, Peru, and Bolivia, to Chile and Argentina in the south. Its range extends to adjacent Pacific coastal regions in Peru and Chile and over lowland Patagonian steppes in Argentina. It primarily inhabits open, non-forested areas, including high-altitude páramo and punal grasslands, rocky cliffs used for nesting and roosting, and coastal deserts where it exploits marine mammal carcasses. Occasional vagrants have been recorded in Panama and the Falkland Islands.

Ecology and behavior

As an obligate scavenger, the Andean condor plays a crucial ecological role by consuming carrion, primarily from large ungulates like guanaco and domestic cattle, and occasionally beached sea lions. It relies on its exceptional eyesight to locate food, often soaring for hours on thermal updrafts with minimal wing flapping. It is a social species, often gathering at large carcasses, though a strict dominance hierarchy is enforced, typically with adult males dominating. Breeding is slow, with a clutch of one egg laid every other year in a cliffside nest; both parents share in the lengthy incubation and fledgling care period, which can exceed a year. Its flight is aided by the mountain range's topography, which generates the necessary air currents for its immense wings.

Relationship with humans

The condor holds profound cultural significance, featuring prominently in the mythology and art of pre-Columbian civilizations like the Nazca, Moche, and Inca. It is considered a symbol of power and health in Andean cultures and is a national symbol of Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru, appearing on their coats of arms, currency, and postage stamps. Historically, it has been used in the ritual ceremony of the Yawar Fiesta in Peru. However, it has also faced persecution from ranchers who mistakenly believe it preys on livestock, leading to widespread poisoning and shooting.

Conservation status

The Andean condor is classified as Vulnerable on the IUCN Red List. Primary threats include secondary poisoning from carcasses intended for predators like pumas and foxes, direct persecution, lead poisoning from ingested ammunition, and habitat loss. Conservation efforts are multinational, involving captive breeding and reintroduction programs, such as those led by the Buenos Aires Zoo and organizations in Colombia and Venezuela. It is listed on Appendix I of the CITES and is protected by national laws across its range, including within numerous protected areas like Los Glaciares National Park and Sajama National Park.
