Differences between Rook and Sparrow

Rook and Sparrow are two classes of birds that belong to the Corvidae and Passeridae families respectively.

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.

Sparrows are one of the most commonly found birds in the world. They are petite birds with a round head and small beak that is shaped like a cone. Their plumage is either brown or grey with white streaks. The feather on their belly is usually white. The birds have a long and stiff tail. An interesting fact about Sparrows is that they have a bone in their tongue. As these are perching birds, they have clawed feet with three forward-pointing and one backward-pointing toe. Sparrows are songbirds that make chirping sounds. There are over 140 species of these birds in the world. They are generally classified as Old World species and New World species. Sparrows are mentioned in mythology and the Bible. Their earliest fossils, found in caves in Israel, are dated back to over 100,000 years.

Where are Rook and Sparrow found?

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.

Sparrows prefer thick forests, open fields, agricultural farms, and fringes of forests. However, a large population of Sparrows also live in the parks, gardens, and buildings of cities. The Old World species of Sparrows originally belong to Asia, Africa, and Europe. The New World species have been introduced in North America, South America, Australia, and New Zealand.

Where do Rook and Sparrow nest?

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.

Sparrows build their nests in holes and cavities of small trees, in shrubs, and buildings. They prefer their nests to be closer to the ground. The nests generally look spherical and measure eight to 10 inches in diameter. The female and male partners construct the nest using straw, twigs, roots, leaves, grass, paper, thread, wool, and feather. The eggs are completely white, or bluish white, or greenish white with brown spots. Both partners incubate the eggs. The eggs hatch in 10-14 days. The young ones that are fed by both parents fledge in about two weeks.

How long do Rook and Sparrow live?

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.

Sparrows are known to live for four to seven years. Some species can even live up to 20 years. The House Sparrows live until 23 years in captivity.

Are Rook or Sparrow migratory birds?

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.

Not all Sparrows are migratory. The ones from Canada, North America, northern parts of Europe, and east Asia migrate during winters. The House Sparrows typically do not migrate as they do not encounter harsh weather or scarcity of food in any time of the year. Among the migratory species, American Tree Sparrow migrates from North America and Canada to the USA, while the Savannah Sparrow travels from Alaska to the USA. In northern and central Europe, migration takes place among Eurasian Tree Sparrow that relocates to Africa. The Russet Sparrow is a species from Himalayas that spends its time in south-east Asia during winters.

Do Rook and Sparrow fly in flocks?

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.

A group of Sparrows is called a flock. The birds are highly sociable. They live in colonies of about 20 birds, which may even extend to about a 100. The birds are always found in groups, foraging, flying, and roosting together. Their nests are also built next to each other during the breeding season. Sparrows are also intelligent birds. They are known for cooperation and teamwork. The birds work together to find food, build nests, preen feathers, and remove lice and parasites from their skin. They chirp incessantly to let their group know about where they are. As Sparrows are tiny birds, living in large flocks also helps in intimidating the predator and also mobbing the predator if required.

Can Rook and Sparrow fly?

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.

Sparrows fly by taking off directly, flapping their wings, and folding their legs. Their average flying speed is 24-31 miles an hour. The altitude range they can fly at varies for different species. While most of them normally fly at around 500 feet, some fly at around 2,000 feet. During migration they fly 5,000-20,000 feet high and cover 15-600 miles in a day. Sparrows fly in flocks because they are tiny birds and flying in groups supports energy conservation. It will also help them spot and threaten predators.

Mating patterns among Rook and Sparrow

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.

Depending on the species, Sparrows start mating when they are five to nine months old. The birds mate in small colonies. During courtship, the male hops around the female with inflated chest, raised tail, and slouched wings. He also chirps and sings for her. The partners copulate until the female can lay eggs. They produce nearly four broods in a breeding season. The female lays one to eight eggs in a clutch. Both partners incubate the eggs and raise the chicks.
