Condors prefer nest sites high on cliff ledges or cave openings with sand on the bottom.
Holes in very large trees, like sequoias or redwoods, also make for great condor nest sites, although no nest itself is constructed for the egg and the condor pair doesn't add any nesting material. Vulture culture. California condors are vultures. Like all vultures, they are carrion feeders, not predators.
They eat anything that is already dead, ranging in size from mice to beached whales. Condors do not have talons like hawks or eagles do; instead, their nails are more like blunt claws.
They also do not have a toe that faces backward opposing , so they cannot grasp or carry prey with their feet. Condors prefer to eat large, dead wildlife like deer, cattle, and sheep, but they also eat rodents, rabbits, and even fish. These large birds gorge themselves on 2 to 3 pounds 1 to 1. Without them, things could get pretty messy! When a condor finds a food source, it often cases out the situation for days, safely perched on a hillside watching the carcass, or it flies in a circle for a long time before landing.
Eventually, the condor flies down to the feeding site to dig in. At the San Diego Zoo Safari Park, the adult condors eat either rabbits, rats, beef spleens melts , trout, or a ground meat specifically made for carnivores four days a week. They are not given the same items every time, as they would encounter different types of food in the wilderness. Condor etiquette. California condors have a complex social system.
Condors, like other vultures, are social birds that share food and spend time resting near one another. They use a variety of body postures to communicate with one another to maintain social hierarchies. Adults may grunt, wheeze, or hiss. Chicks can make a high-pitched, scraping squawk, usually when begging or when out from under the parents for too long. The adult female lays a single whitish or pale green-blue egg directly on the substrate of dirt, pebbles, or woodchips between January and March.
Both parents incubate the egg and care for the chick, and they may only raise one chick every other year. If that egg is lost predation, accident, etc.
Although adult condors have no predators other than humans , eggs and chicks may be attacked in the nest by ravens or golden eagles. Pipping forth. It uses a sharp point on its beak called an egg tooth to crack through the shell, but it can still take many hours, or even days, for the chick to completely break free. The chick hatches with bare skin on its head, neck, belly, and underwings.
Both parents brood the chick, keeping it warm after hatch. They may squabble with each other for brooding time, but they soon settle into a routine, and the nest exchanges become much calmer. After about a day, the chick can hold its head steady, and the parents then start providing food.
