California Condor (Gymnogyps californianus): Facts and Recovery

Appearance: how to recognize a California condor

Adult California condors are mostly black. Underneath each wing is a large white triangle, which is the easiest field mark when a condor soars overhead. The head and neck are almost bare of feathers, with skin that ranges from yellow to bright orange and pink in adults. A ruff of black feathers circles the base of the neck, and the bill is pale ivory.

Young condors look different. They have dark gray heads and mottled gray rather than white wing linings, and they only reach full adult colors at about 6 years old. Many free-flying birds also carry large numbered tags and small radio or GPS transmitters on their wings, which lets biologists follow each bird.

The bare head is a practical design. A condor pushes its head deep inside carcasses, and bare skin stays cleaner than feathers would. The skin can also flush with color during courtship and squabbles at a carcass. Read more in why are vultures bald?.

The feet are surprisingly weak. The talons are straight and blunt, built for walking around a carcass rather than grabbing live prey, which is a key difference from eagles and hawks.

Size: how big is a California condor?

The California condor is a heavyweight. Typical measurements, mostly from birds measured in captivity, are:

No other North American bird has a wider wingspan. Only the trumpeter swan and the introduced mute swan are heavier on average. Claims of wingspans above 3.4 m (11 ft) appear in old reports, but nothing over about 3 m (10 ft) has been verified.

Unusually for a bird of prey, males are slightly larger than females. Its South American cousin, the Andean condor, is heavier and has a slightly larger wingspan, and the wandering albatross beats both in wingspan. See the largest birds in the world for how the condor ranks.

Habitat and range

Before European settlement, California condors ranged along the Pacific coast from British Columbia to Baja California and across parts of the American Southwest. Fossils show that during the Ice Age the genus Gymnogyps lived as far east as Florida, when mammoths, giant bison and other huge animals provided plenty of carcasses.

Today condors live only where they have been released and in the areas they have spread to since:

• California: the coastal mountains around Big Sur and Pinnacles National Park, the mountains of southern California, and the redwood coast of the far north, where the Yurok Tribe began releases in 2022.
• Arizona and Utah: the Vermilion Cliffs and Grand Canyon region, with birds now nesting in Zion National Park.
• Mexico: the Sierra de San Pedro Mártir in northern Baja California.

Condors need open country for soaring and finding food, and cliffs, caves or very large trees for nesting and roosting. They live in rugged mountains, canyons, rocky scrubland, oak savanna and conifer forest, and along wild coastlines where they may feed on dead sea lions and whales.

Diet: what do California condors eat?

California condors are obligate scavengers: they eat carrion, meaning animals that are already dead. They prefer the carcasses of large mammals such as mule deer, elk, cattle, sheep and goats, plus ground squirrels, rabbits and other smaller animals. On the coast they also feed on dead sea lions, seals and the occasional beached whale.

A condor can go several days or even two weeks without food, then eat more than 1 kg (2.2 lb) of meat at one sitting. Wild condors cover huge distances to find food, sometimes traveling more than 250 km (155 mi) in a day.

Condors do not have a strong sense of smell, unlike the turkey vulture, which can sniff out carcasses hidden under trees. Instead condors watch the landscape and other scavengers, such as ravens, eagles and turkey vultures, to find a meal. Their size lets them push most other scavengers aside and tear open tough hides. Golden eagles and bears are the main exceptions.

Flight and behavior

Condors are built for soaring rather than flapping. They flap to take off, then ride rising columns of warm air called thermals and updrafts along ridges and cliffs. A soaring condor may travel for kilometers without flapping, reaching speeds of up to about 90 km/h (56 mph) and heights above 4,500 m (14,800 ft).

Because flight is easier once the air warms, condors often spend early mornings roosting, preening and sunbathing with their wings spread. They bathe often and can spend hours cleaning their feathers.

California condors are social and intelligent. Groups roost together and feed together, and there is a clear pecking order at a carcass, with dominant adults eating first. Condors cannot sing or call like most birds because they lack a voice box (syrinx); they communicate with hisses, grunts and body language.

Reproduction and life cycle

California condors breed slowly, and this is one of the main reasons the species is so vulnerable. Birds usually start breeding at about 6 years old or later and form long-lasting pairs.

A female lays a single egg, usually between January and April, in a cave, a cliff ledge or, less often, a hollow in a giant tree such as a redwood. Both parents incubate the egg for about 53–60 days. The chick can fly at 5–6 months old but depends on its parents for many more months, so a successful pair usually nests only every other year.

If an egg is lost early in the season, the pair often lays a replacement egg. Biologists used this “double clutching” to speed up captive breeding: the first egg was taken to be hatched in an incubator, and the parents laid another. Chicks raised by people were fed with hand puppets shaped like condor heads, so they would not imprint on humans.

Lifespan

California condors are among the longest-lived birds in the world. Biologists expect a healthy wild condor to live for 50 years or more, and lifespans of up to about 60 years have been reported. The full potential is still uncertain because few wild condors have lived long enough to reach old age since the recovery began.

Predators and threats

A healthy adult condor has few natural enemies. Ravens may take eggs, and golden eagles, bears and coyotes can kill chicks or young birds. The real threats come from people:

• Lead poisoning is the biggest problem. Condors swallow fragments of lead bullets in carcasses and gut piles left after shooting. Lead was the leading known cause of death among free-flying juveniles and adults between 1992 and 2013, accounting for more than half of those deaths. California banned lead ammunition in condor range in 2008 and statewide from 2019.
• Microtrash such as bottle caps, glass and wire is picked up by parents and fed to chicks, and it has been a leading cause of death in nestlings.
• Power lines once killed many released birds. Young condors are now trained in captivity to avoid them.
• Disease can strike suddenly. In 2023 an outbreak of highly pathogenic bird flu killed 21 condors in the Arizona and Utah flock, and biologists began vaccinating birds.

Historically, condors were also shot, poisoned by baits meant for other animals and harmed by egg collecting and the pesticide DDT, which thinned eggshells.

Conservation status and recovery

The IUCN lists the California condor as Critically Endangered, and it is protected under the US Endangered Species Act. Its rescue is one of the boldest and most debated efforts in conservation history.

By 1982 only 22 condors were left. After intense debate, the US Fish and Wildlife Service decided to capture every remaining wild bird. The last one, a male known as AC-9, was taken on April 19, 1987, leaving 27 condors in total, all in captivity at the San Diego Wild Animal Park and the Los Angeles Zoo. Captive breeding later expanded to the Oregon Zoo and The Peregrine Fund’s World Center for Birds of Prey in Idaho.

Releases began in California in 1992, in Arizona in 1996 and in Baja California in 2002. The first chick fledged in the wild in 2003, and in 2015 more chicks hatched in the wild than condors died there for the first time. The US Fish and Wildlife Service counted 607 California condors at the end of 2025, with more than half flying free and the rest in breeding centers.

The species still depends on people. Many wild birds are trapped regularly to test their blood for lead, and some need treatment to survive. Biologists say the wild flocks will not be self-sustaining until lead exposure falls much further.

Myths and facts

Myth: The California condor is the biggest bird in the world. It is the biggest flying land bird in North America, but the Andean condor is heavier and albatrosses have longer wings. Ostriches and other flightless birds are far larger.

Myth: Condors kill livestock. Condors are scavengers. Their weak, blunt-clawed feet cannot hold live prey, and they feed on animals that have already died.

Fact: Condors were once found across much of North America. During the Ice Age, condors fed on the carcasses of mammoths and other giant mammals across North America. When those animals disappeared, condor numbers shrank, which is why the species was confined to the West long before modern threats.

Relationship with people

The condor features in the traditions of many Native American peoples of California and the West. Different nations saw it as a creator, a destroyer or a messenger, and condor feathers were used in ceremonial dress. The Yurok Tribe calls the condor prey-go-neesh and leads the reintroduction in northern California.

Today the condor is also a symbol of modern conservation. Its recovery has cost tens of millions of dollars and involved zoos, government agencies, tribes, ranchers, hunters who switch to non-lead ammunition and thousands of volunteers.
