Differences between Condor and Rook

Condor and Rook are two classes of birds that belong to the Cathartidae and Corvidae families respectively.

Condor includes two species of New World Vultures, namely, the Andean Condor and the California Condor. They are one of the largest flying birds in the world. The Andean Condor is characterized by black feathers with white patches at the tip of wings. Its neck is covered with white fur, while the head is red and bald. The bird’s talons are straight and blunt and its beak is curved. The California Condor is generally black with white patches below the wings. The neck and head are yellowish orange without any feathers. These birds do not have talons and the backward toe for grasping. The beak is hooked and has an egg tooth.

Rook is a Eurasian bird that resembles the Crow. It has black plumage with purple sheen in addition to bushy feathers on its thighs. The bill is sharp and slightly curved. The legs are black with three forward and one backward toe. The bird differs from Crow and other members of the family by the white bare skin at the base of its bill. It is however as intelligent as other species of the Corvidae family. It can solve puzzles, plan in advance, build and apply tools, mimic human vocabulary, and display sophisticated behavior. The Rook family consists of two sub-species, namely, the Western Rook and the Eastern Rook.

Where are Condor and Rook found?

Andean Condors are found in mountains, deserts, and coasts. They exist in Andes mountains and parts of western South America. On the other hand, California Condors live in rocky shrubs and coniferous forests. They can be found in southern parts of Californian deserts besides Mexico, Utah, and Arizona.

Rooks prefer open grasslands, agricultural fields, and pastures with ample tall trees for breeding. The birds can be found in the fringes of towns and cities. Rooks exist in the UK, Ireland, Iran, northern and central Europe, parts of Asia, and New Zealand.

What do Condor and Rook eat?

Andean Condors and California Condors are both carnivores and scavengers. They eat dead deer, sheep, pigs, cows, and other large mammals. On rare occasions they hunt small creatures like rodents, rabbits, and small reptiles.

Rooks are omnivores. They dig into agricultural fields for insects, larvae, and worms. They also eat beetles, larger insects, mice, small birds, eggs, seeds, grains, carrion, and food waste thrown away by humans.

Size of Condor and Rook?

When it comes to size, Andean Condors are one of the largest flying birds in the world with a height of nearly four feet and a wingspan of 10 feet. California Condors are nearly as large with a height of 3.5-4.5 feet and a wingspan of about 9.8 feet. They are the largest flying birds in North America.. Rooks are 1.4-1.5 feet long. They have a wingspan of three feet.

Condors are also huge in terms of weight. Andean Condors weigh 16.9-33 pounds. Meanwhile, the average weight of California Condors is 18-20 pounds. while The average weight of Rooks is 11.99-18.69 ounces.

Where do Condor and Rook nest?

Andean Condors make their nests with sticks on safe rims of rocks or ledges of cliffs in higher elevation. Their eggs are bluish white with a weight of 9.9 ounces. Both partners take turns to incubate the eggs for 58-60 days. The chicks fledge at around six months but continue to be under the care of their parents for 10 months to two years. California Condors use mountain caves or tree cavities to lay eggs. They surround the eggs with gravel, sticks, or bones. The eggs are bluish green in color and weigh 10 ounces. Both male and female share duties of incubating and nesting the young ones. The eggs hatch after 53-60 days. The young ones fledge in about four months but remain with the parents for a year.

Rooks build large nests in colonies that are known as rookeries. They are constructed with twigs and lined with mud, moss, leaves, grass, hair, and wool. The nests stand freely on tall trees. Both male and female partners involve themselves in the construction of the nests. In some instances, they use old nests from previous years. The eggs are greenish white and sometimes have dark spots on them. They are about four centimeters long. The mother Rook incubates the eggs for 16-18 days. During this time, she does not leave the nest and gets fed by her partner. After the eggs hatch, both partners take turns to feed the young ones. The chicks fledge when they are four weeks old but continue to secure food from the parents for more time.

How long do Condor and Rook live?

Both species of Condors have a long lifespan. Andean Condors live up to 50 years in the wild. The oldest lived bird died at 80 years in January 2010 at the Beardsley Zoo in USA. California Condors have an average lifespan of 60 years. Of the living California Condors, the oldest is a male that hatched in April 1966.

The average lifespan of Rooks is five to 10 years. However, through bird banding it has been observed that some Rooks live up to 20 years.

Are Condor or Rook migratory birds?

Andean Condors and California Condors are not typical migratory birds although they fly long distances. They do not travel in search of new habitats, instead travel nearly 125 miles a day looking for food.

The migration of Rooks depends on their location. The ones living in the southern hemisphere are mostly residents. The birds in the north relocate to the south during winters. They migrate in large flocks along with other species from their family, especially the Jackdaws. They return to their rookeries at the onset of spring. Rooks from northern parts of Europe and Asia migrate to southern Asia, western Europe, and the Middle East for wintering.

Do Condor and Rook fly in flocks?

A group of Condors is called a Condo. Andean Condors are mostly solitary. They live in small groups of three or four having both male and female birds. They may roost in colonies. Contrastingly, California Condors are more social. They spend time with their groups and also follow a social hierarchy. They eat together but following a pecking order.

A flock of Rooks is known as parliament, building, or clamor. Rooks are the most sociable in the Corvidae family. They are always spotted in large groups. They forage in flocks and use various vocalization to communicate. The birds are also known to play amongst themselves. In addition, Rooks sleep in big groups and nest together in large colonies.

Are Condor or Rook protected?

Both Condor species are protected by law in the USA. They are categorized under the Endangered Species Act, under which harming or killing them is punishable.

Rooks are protected under the Wildlife and Countryside Act in the UK. However, they can be killed with a permit to protect crops and livestock, and for the safety of aircrafts. Similar laws exist in other parts of Europe and Asia.

Are Condor or Rook endangered?

Andean Condors are listed as threatened. They are extinct in Venezuela. Their population is under threat because of hunting by farmers to save their livestock and poisoning from pesticides. They also face danger from electrocution, eating trash, and exposure to pesticides. California Condors are listed as critically endangered. Only a few hundreds of them are remaining but their numbers are increasing due to captive breeding. These birds are being reinstated into the wild.

The International Union for Conservation of Nature has classified Rooks as species of least concern. The birds are not endangered. They exist in millions in their territorial countries.

Can Condor and Rook fly?

The Condor species fly by using thermals and flap their wings as infrequently as once an hour. Owing to their large size, they prefer to fly in windy regions. They can reach flying speeds of 55 miles an hour and soar at altitudes of 15,000 feet.

Rooks typically fly in large flocks. They keep their wings stiff during direct flights. They sometimes soar high in the company of Jackdaws. They fly at a speed of 32-45 miles an hour during migration.

Can Condor and Rook swim?

Condors are not built to swim. They are not water birds. They are huge and fly in search of food.

Rooks do not have webbed feet like waterbirds. Their body is not adaptable for swimming.

Mating patterns among Condor and Rook

Andean Condors reach sexual maturity when they turn five or six years. They have the longest breeding cycle among all birds in the world. They reproduce during alternate years. During courtship, the male’s neck changes color to bright yellow. He hisses and coos while dancing and hopping around the female with his wings partly spread out. The partners share a close bonding and raise the young ones jointly for a year. California Condors start mating when they are six to eight years old. They lay one egg every two years. Courtship will include the male performing displays, extending his wings, and dancing by moving his legs. The female also performs displays with her wings. The partners share the responsibility of incubating and tending to the young ones. The female California Condors are known to be able to reproduce asexually without mating.

Rooks generally start mating when they are two years old. The male Rook sets the ground for courtship by bowing to the female, swinging his tail, and crouching his wings. He will also fetch food for her. The female will bow in return, ruffle her wings, and spread out her tail in acceptance. The partners caress each other’s bill and sing while mating. They are likely to be assaulted by other male birds. The female lays three to four eggs every breeding season. She takes the responsibility of incubating the eggs while the male fetches food for her. Once the eggs hatch, the partners feed the young ones during nesting and even for few weeks after fledging.

When is the mating season for Condor and Rook ?

Andean Condors mate during February-June. In the case of California Condors, the mating season is from December to April.

The mating season for Rooks is March-June. The migratory birds return to their territories when spring sets in.

Do Condor and Rook mate for life?

Both Condor species are monogamous and mate for life. They also live with their offspring for longer than most other birds.

Rooks are monogamous and generally mate for life. Nevertheless, there may be instances of bigamy. A nest could be used by multiple females.

How do Condor and Rook sleep?

Andean Condors and California Condors roost in groups on elevated cliffs or tall trees to keep themselves safe from predators on the ground. They however sleep near their nests during the breeding season.

Rooks spend the nights in enormous flocks. As the sun sets, a noisy group of birds return to roosting sites. They sleep on branches in woodlands or even settle down in their rookeries. At daybreak, the birds disperse in different directions in search of food.

Can Condor and Rook be eaten?

Although consumption of scavenging birds is not desired, people are not averse to Rook meat. The meat of young Rooks is said to be more delectable than that of adult Rooks.

Can you hunt Condor or Rook?

Reduction in the population of California Condors has chiefly been attributed to hunting by farmers who killed the birds to save their livestock. Farmers have also killed Andean Condors. Therefore, to save these species that are endangered, laws have been introduced prohibiting any kind of harming or killing.

Shooting young Rooks was a sport in the UK in earlier years. This served the purpose of sport, pest control, and hunting for meat. Rooks are known as agricultural pests. Killing them with with a license is permitted in most parts of the world as they destroy livestock and crops. They also rummage waste bins and cause health hazards to humans.

Can you feed Condor or Rook?
