What is a condor?
Condors are New World vultures, with the Andean condor and the California condor being the largest flying birds. The Andean condor has a wingspan of up to 3.2 meters (10.5 feet), while the California condor reaches about 2.9 meters (9.5 feet). From beak to tail, they are about 1.2 meters (4 feet) long.
Adult California condors are mostly black, with white wing linings and a bare red-to-orange head, neck, and crop. They nest in cliffs or natural cavities and breed every other year, laying one greenish-white egg. They forage in open country and feed on dead animals. The Andean condor is a black bird with grayish-white wing feathers and a red or pinkish head.

Where do condors live?
Condors include the Andean condor (Vultur gryphus) and the California condor (Gymnogyps californianus). Andean condors live throughout the Andes Mountains of South America, but they are rare in the northern part of the continent. In Peru and Chile, they inhabit the Pacific Coast. California condors primarily inhabit the California deserts, though there are established populations in Mexico, Utah, and Arizona. Fossil records suggest that they once roamed as far east as Florida and New York.

What do condors eat?
Condors are carnivorous scavengers that feed on carrion (the carcasses of dead animals). Both the Andean condor and the California condor search for the carcasses of large animals such as cattle and deer. The Andean condor also feeds on dead marine animals such as seals and fish along the Pacific coast in Peru and Chile. California condors can travel hundreds of miles daily in search of food.

How can you tell condors apart from other large birds?
Condors are New World vultures, with two species: the Andean condor and the California condor. They are among the largest flying birds; the Andean condor has a wingspan of up to 3.2 meters (10.5 feet), while the California condorās wingspan typically reaches 2.9 meters (9.5 feet).
Adult California condors are black with a white triangular mark on the underside of each wing. Andean condors are mostly black, with grayish-white wing feathers, a white neck fringe, and a bare red or pinkish head and neck. Male Andean condors have a fleshy protuberance on their forehead. Condors have bare heads and necks, which prevent scavenged meat from sticking to their feathers.

Why are condors considered endangered?
California condors are endangered due to factors such as settlers killing the birds, decreasing food supply, and environmental pollutants. Lead poisoning from consuming carcasses with bullet fragments also contributes to their endangerment.
Conservation efforts started in 1980, with researchers capturing condors and placing them in zoos for breeding. In 1987, the last wild adult condor was captured. The captive breeding program led to the release of condors back into the wild. By 2020, the California condor population numbered around 500, with approximately 330 in the wild.

What is being done to help protect condors in the wild?
The California condor population declined sharply as settlers moved into the American West. Habitat protection and protective custody have been essential to the condor's recovery.
Conservationists initiated a large conservation project in 1980, capturing condors and placing them in zoos with the hope that they would reproduce and later be released into the wild. By 1987, the last wild adult condor was captured. Captive condor chicks began hatching in 1988, and the first two were released into the wild in 1992.
In 2020, the U.S. Fish and Wildlife Service estimated that there were about 500 California condors in the world, with approximately 330 in the wild.

Condor, either of two large New World vulturesāthe Andean condor (Vultur gryphus) and the California condor (Gymnogyps californianus)āthat are two of the largest flying birds. Wingspans up to 3.2 metres (10.5 feet) have been reported for male Andean condors, and adult California condors typically reach 2.9 metres (9.5 feet). From beak to tail, the body of each is about 1.2 metres (4 feet) long. Male Andean condors may weigh up to 15 kg (33 pounds), and female Andean and both sexes of California condors may reach 11 kg (24 pounds) in weight.
Andean condor
The male Andean condor is a black bird with grayish white wing feathers, a white fringe of feathers around the neck, and a bare red or pinkish head, neck, and crop. Males have a large caruncle, or fleshy protuberance, on the forehead and top of the beak, and turkeylike neck wattles. The species ranges throughout the Andes Mountains of South America, frequenting open country and feeding on carcasses. When hunting for prey, the Andean condor soars on thermals (warm updrafts that rise from the land below) and upslope winds to remain aloft and can glide for more than 160 km (100 miles) without flapping its wings. In Peru and Chile it descends to the Pacific coast, where it feeds on dead marine animals such as seals and fish.
Andean condors are rare in northern South America but still relatively common in the southern part of their range. About 6,700 adult Andean condors remain, and the International Union for Conservation of Nature and Natural Resources (IUCN) has classified the species as near threatened.

They breed every other year unless the hatchling dies, in which case the pair breeds again the following year. The young are raised on remote ledges and in caves at altitudes above 3,000 metres (10,000 feet), using no nesting material. The white egg measures about 12 cm (4.5 inches) long.
California condor
Adult California condors are mostly black, with bold white wing linings and a bare red-to-orange head, neck, and crop. Young birds have a dark head that gradually becomes red as they near adulthood at about six years of age. They forage in open country and feed exclusively on carrion. California condors nest in cliffs, under large rocks, or in other natural cavities, including holes in redwood trees. They generally breed every other year, laying a single unmarked greenish white egg measuring about 11 cm (4 inches) long. Although most California condors reproduce sexually, some female birds have been able to reproduce asexually through parthenogenesis. In 2021 researchers reported that two captive female birds produced chicks that hatched from unfertilized eggs.
The California condor is critically endangered. By 1982 only 20 remained in the wild, and efforts were made to establish a captive breeding flock in zoos. Because of excessive mortality from lead poisoning and shooting, the wild population continued to decline, and in 1987 the last free-flying survivor was trapped and taken into protective captivity. The first successful captive breeding occurred in 1988, and numerous captive progeny were released to the wild beginning in 1992. These conservation efforts enabled the total California condor population to reach 289 by mid-2006, including 138 wild birds in southern and central California, northern Arizona, and northern Baja California, Mexico. In 2002 the first egg to be laid in the wild by captive-raised condors hatched, and by mid-2010 44 adults had produced viable offspring in the wild. By 2020 the wild population numbered more than 300, with some 180 living in captivity.
