'''Condor''' is the common name for two [[species]] of [[New World vulture]]s, each in a [[monotypic]] [[genus]]. The name derives from the [[Quechua language|Quechua]] ''kuntur''.<ref>{{Cite encyclopedia| title=Raven|encyclopedia=Oxford English Dictionary|editor1=J. Simpson |editor2=E.

One species, the [[Andean condor]] (''Vultur gryphus''), inhabits the [[Andean]] mountains. The other, the [[California condor]] (''Gymnogyps californianus''), is currently restricted to the [[Pacific Coast Ranges|western coastal mountains]] of the [[contiguous United States]] and [[Mexico]], as well as the northern desert mountains of [[Arizona]].

==Taxonomy==
{{Further|Andean condor#Taxonomy and systematics|California condor#Taxonomy}}
Condors are part of the family [[Cathartidae]], which contains the New World vultures, whereas the 15 species of [[Old World vultures]] are in the family [[Accipitridae]], which also includes [[hawk]]s, [[eagle]]s, and [[Kite (bird)|kites]]. The New World and Old World vultures evolved from different ancestors. They both are [[carrion]]-eaters and the two groups are similar in appearance due to [[convergent evolution]].

The adult [[plumage]] is uniformly black, except for a frill of white feathers nearly surrounding the base of the neck, which are meticulously kept clean by the bird. As an adaptation for hygiene, the condor's head and neck have few feathers, which exposes the skin to the sterilizing effects of dehydration and solar ultraviolet light at high altitudes. The head is much flattened above. In the male, it is crowned with a caruncle or comb, while the skin of the neck lies in folds, forming a wattle. The head and neck skin can flush noticeably in response to the emotional state and transmitted between individuals.<ref name="Ferguson-Lees"/> In Andean condors, specifically males, there is typically an extra group of skin,{{clarify|date=December 2024}} much like that of a turkey. Alternatively, Andean condors often have a white feather collar at the base of their head. Most California condors are without an extra plumage and display a longer neck than that of the Andean.

[[File:California-condor.jpg|thumb|right|Immature California condor|210x210px]]

The middle toe is greatly elongated, the hind one is slightly developed, and the nails of all the toes are comparatively straight and blunt. The feet are thus more adapted to walking (as in their closely related storks) and of little use as weapons or organs of prehension (as in birds of prey and Old World vultures). Contrary to the usual rule among [[Bird of prey|birds of prey]], the female is smaller than the male.<ref name="Ferguson-Lees"/>

California condors' skin on the neck varies in color, depending on the age of the birds. During the breeding season, adult birds' skin color can be cream, pink, yellow, or orange.<ref name="Ferguson-Lees"/> Most commonly, Andean tend to utilize white or black skin tones, while the California condor leans towards pink.

==Fossil record==

Fossils of both extinct and extant condor species from the [[Pleistocene]] era have been found in various parts of [[North America]], including New York and Florida, leading scientists to hypothesize that California condors (as well as their ancestors and relatives) once lived on the west coast of North America as well as to the eastern coast, until their eventual extinction/extirpation. Some scientists also have found that an ancient relative of the condor, ''[[Argentavis|Argentavis magnificens]]'' from South America, may have been the largest flying bird ever with a wingspan of up to twenty-four feet.<ref>Campbell, K.E. & Tonni, E.P. 1983. Size and locomotion in teratorns (Aves: Teratornithidae). Auk. 1983; 100(2): 390-403</ref>

==Behavior==
{{Further|Andean condor#Ecology and behavior|California condor#Ecology and behavior}}
Sexual maturity and breeding behavior do not appear in the condor until 5 or 6 years of age. Condors are monogamous creatures and will mate for life. They may live for 50 years or more and the world's oldest condor died at 100 in the [[Jardin d'Essai du Hamma]] in [[Algiers]].<ref>{{cite web |url=http://www.ennaharonline.com/en/news/4416.html |title=The world's oldest condor dies |publisher=Ennahar Online |date=2010-07-28 |access-date=2014-06-02 |archive-url=https://web.archive.org/web/20140605053251/http://www.ennaharonline.com/en/news/4416.html |archive-date=2014-06-05 |url-status=dead }}</ref> Condors nest with one chick at a time, laying one egg every year to year and a half. Due to their size, condors require lots of care and nutrition very early on in their chick stage.<ref name=":1" />

These birds tend to be more social than other birds of prey. They often clump in smaller groups and socialize and rest together. They will often revisit the same locations for daily activities and seasonal roosts. 

The young are covered with a grayish down until they are almost as large as their parents. They can fly after six months but continue to roost and hunt with their parents until age two, when they are displaced by a new clutch. There is a well-developed social structure within large groups of condors; a recent study showed the '[[Dominance hierarchy|pecking order]]' is determined by age group and, within age groups, by sex (which contradicts previous findings).<ref>{{Cite journal |last=Handler |first=Ian |date=2018 |title=Andean condor nesting and behavior: A study of a free-living pair and chick as well as population behavior near Antisana Ecological Reserve, Ecuador |url=https://core.ac.uk/download/pdf/232740742.pdf |journal=SIT Digital Collections |pages=18}}</ref><ref>{{Cite journal |last1=Donázar |first1=José A. |last2=Travaini |first2=Alejandro |last3=Ceballos |first3=Olga |last4=Rodríguez |first4=Alejandro |last5=Delibes |first5=Miguel |last6=Hiraldo |first6=Fernando |date=1999-01-01 |title=Effects of sex-associated competitive asymmetries on foraging group structure and despotic distribution in Andean condors |url=https://doi.org/10.1007/s002650050539 |journal=Behavioral Ecology and Sociobiology |language=en |volume=45 |issue=1 |pages=55–65 |doi=10.1007/s002650050539 |bibcode=1999BEcoS..45...55D |hdl=10261/39777 |s2cid=24420560 |issn=1432-0762|hdl-access=free }}</ref>

The lack of a large sternum to anchor correspondingly large flight muscles identifies it physiologically as a primary soarer. The birds flap their wings on rising from the ground, but after attaining a moderate elevation, they seem to sail on the air, transiting from one upstream to the next, often without flapping their wings. One Andean condor was recording maintaining such flight for {{Convert|106|mi|km|order=flip|sp=us}}, for over five hours.<ref>{{Cite news |last=Dvorsky |first=George |date=July 14, 2020 |title=Andean Condor Soared for 100 Miles Without Flapping Its Wings |url=https://gizmodo.com/andean-condor-soared-for-100-miles-without-flapping-its-1844380679 |access-date=2022-05-18 |work=Gizmodo |language=en-us}}</ref> Because of their size, these birds tend to rely on strong [[Thermal current|thermal currents]] to propel them higher into wind currents. <ref>{{Cite web |title=Andean Condor |url=https://abcbirds.org/bird/andean-condor/ |access-date=2024-11-06 |website=American Bird Conservancy |language=en}}</ref>

Wild condors inhabit large territories, often traveling {{convert|250|km|mi|-1|abbr=on}} a day in search of carrion. With such a large wingspan these birds can sometimes can get by with one single wing flap over an hour.<ref>{{Cite web |title=Andean Condor |url=https://lazoo.org/explore-your-zoo/our-animals/birds/andean-condor/#:~:text=IUCN%20Red%20List-,About,hour%20while%20soaring%20and%20surveying. |access-date=2024-11-06 |website=Los Angeles Zoo and Botanical Gardens |language=en-US}}</ref> They prefer large carcasses, such as deer or cattle, which they spot by looking for other [[Scavenger|scavengers]]. However, these rival species cannot rip through the tougher hides of these larger animals with the efficiency of a larger condor. In the wild, they are intermittent eaters, often going for a few days without eating, then gorging themselves on several kilograms (pounds) at once, sometimes to the point of being unable to lift off the ground.{{Citation needed|date=March 2017}}

== Habitat ==
Each condor inhabits a very different set of locations. The Andean condor naturally resides in [[South America]], particularly the Western coast. They range from the entirety of the coast, but tend to live towards the [[Andes]] and [[Patagonia]] mountain chains. California condors make up a different global location. As the name implies, these condors tend to live in California and the Southwest United States. Occasionally, the California condor will take up residence in Northwest Mexico. Both species tend to prefer high altitudes, roughly 16,000 feet, for habitat creation. Most commonly these species will reside on the caves or cliffsides of mountains at this altitude range. Occasionally, California condors will also nest in large [[Sequoioideae|redwood]] tree cavities.<ref name=":2">{{Cite web |title=California Condor (Gymnogyps californianus) {{!}} U.S. Fish & Wildlife Service |url=https://www.fws.gov/species/california-condor-gymnogyps-californianus |access-date=2024-11-06 |website=www.fws.gov |language=en}}</ref> Condors instinctively choose locations that naturally protect their young from predators, like [[golden eagle]]s, given the elevation and isolation. A unique component of Andean condor habitat is their

== Threats ==
Both species of condor have significant threats facing their livelihood. The [[International Union for Conservation of Nature|IUCN]] defines the Andean condor as a near threatened species, while the California condor is considered endangered despite recovery programs.<ref>{{Cite web |last=IUCN |date=2020 |title=Gymnogyps californianus |url=https://www.iucnredlist.org/species/22697636/181151405 |website=IUCN Redlist}}</ref> Human threats are currently the more dire to both species. Andean condors tend to be purposefully shot or poisoned because of prejudice or assumed connections between condors and eating cattle. Another threat to Andean condors is local belief in medicinal properties in the bones and organs of the birds, leading to hunting.<ref name=":3">{{Cite web |title=Andean Condor |url=https://abcbirds.org/bird/andean-condor/#:~:text=Andean%20Condors%20play%20an%20important,ruler%20of%20the%20upper%20world. |access-date=2024-11-06 |website=American Bird Conservancy |language=en}}</ref> Human threats are more indirect to California condors, human use of lead in bullets and other items, have become an unintentional part of the condor diet, leading to a dramatic drop in their population over the years. Currently, California has instated a breeding program to aid in recovery, and all the current wild condors are from a subset of twenty-two bred in captivity.<ref>{{Cite web |title=California Condor Life History, All About Birds, Cornell Lab of Ornithology |url=https://www.allaboutbirds.org/guide/California_Condor/lifehistory#:~:text=As%20of%202022,%20all%20550,but%20successful%20captive%20breeding%20program. |access-date=2024-11-06 |website=www.allaboutbirds.org |language=en}}</ref> Such efforts have led to a rise to much higher numbers for the birds.
