California condor6/5/2023 This long period of dependence means that the whole nesting cycle takes more than a year, so after successfully raising one young the condors must skip one nesting season before trying again. Young capable of flight about 5-6 months after hatching, may remain dependent on parents for at least another 6 months. Adult condors harass or chase away potential predators, such as ravens, Golden Eagles, and large mammals, from vicinity of nest. This long period of dependence means that the whole nesting cycle takes more than a year, so after successfully raising one young the condors must skip one nesting season before trying again.īoth parents bring food for young bird. By 1982, there were only 22 of the iconic birds left in the wild. Adult condors harass or chase away potential predators, such as ravens, Golden Eagles, and large mammals, from vicinity of nest. The number of California condors dropped dramatically in the mid-20th century, leading the Service to designate the species as endangered under the Endangered Species Act. Its wings may stretch nearly 10 feet from tip to tip. A holdover from prehistoric times, the great condor is one of our largest and most magnificent birds - and one of the rarest. Young: Both parents bring food for young bird. The California condor is the largest flying bird in North America. Members of pair trade places on the egg once every 1-5 days, rarely taking shifts up to 9-10 days. Despite recovery program success in saving the species from extinction, condors remain. Incubation is by both sexes, about 56 days. The endangered California Condor (Gymnogyps californianus) is the largest New World Vulture in North America. May find much of its food by watching actions of other scavengers (such as vultures or ravens). Forages by soaring, often less than 2000' above ground, looking for carrion. Generally forages only in warmer hours of day, spending morning and evening perched at night roost.

On its last stand in California, the condor foraged over open grassland and savannah, and nested in rugged mountainous terrain with forest and steep cliffs. At one time, ranged over much of the west, from mountains and valleys to the coast. By the mid-1990s, attempts were being made to introduce some of the captive-bred condors into the wild. This breeding program succeeded quite well in raising the numbers of captives, suggesting that it might be possible to reestablish a wild population again. In mid-1980s, all remaining wild condors were caught for captive breeding. Numbers remaining were estimated at about 60 in 1965, fewer than 25 in 1982. In more recent years, poisoning (including lead poisoning), shooting, and collisions with power lines were among causes of death. Early causes included shooting also, many condors died in traps or at poisoned carcasses put out to kill large predators. Decline in numbers was already evident to observers by 1890.
