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

Crow is a large bird with incredible intelligence. It is characterized by shiny black plumage and dark legs. Its beak, eyes, wings, and tail are all black. The bird has four toes on each foot. Crows are particularly known for their cleverness. They have great discerning abilities and have excellent self-control. They can make their own tools, solve problems, remember faces, mimic sounds, and prank other animals. They are also trainable. There are around 40 species of crows across the world.

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 Crow and Sparrow found?

The natural habitat of Crows include grasslands, forests, mountains, agricultural regions, and deserts. They like locations where there are trees. However, these birds are highly adaptable and exist everywhere. They are common sight even in big cities. Crows can be found in all parts of the world. The exceptions are South America and Antarctica.

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.

What do Crow and Sparrow eat?

Crows are omnivores. They are both predators and scavengers. They can eat anything. They eat rodents, reptiles, small mammals, worms, insects, and eggs besides grains, fruits, nuts, and human food.

Size of Crow and Sparrow?

When it comes to size, The size of crows varies for different species. Jackdaw Crow is the smallest with a length of 13-15 inches and wingspan of 27 inches. Thick-billed Raven is the largest among the species. It is 28 inches long with a wingspan of 45 inches.. The size of Sparrows depends on the species.

The weight of the Chestnut Sparrow is 0.5 ounce and that of the Parrot-billed Sparrow is 1.5 ounce.

Where do Crow and Sparrow nest?

Crows build their nests in colonies. The male and female partners start building their nest about a month before the breeding season. Their offspring from previous breeding seasons assist them in nest building. The nests are constructed intellectually, with stronger material laid at the bottom for reinforcement. Crows use all kinds of material available around them to construct the nests. They would include twigs, sticks, hay, plant material, aluminium and copper wire, plastic threads, and wood pieces. The nests are usually placed in tall trees and hidden between trunks for improved safety. However, in cities, crows make their nests in inaccessible parts of tall buildings and billboards. The female incubates the eggs for about 18 days, during which time her partner and other offspring feed her. The newly hatched chicks fly when they are about four weeks old but continue to be fed by their parents and siblings for a longer time. The younger ones live with their parents until they start breeding on their own and sometimes even until they are five years old.

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 Crow and Sparrow live?

The average lifespan of Crows is 11-15 years in the wild and over 20-30 years in captivity. Again, this is dependent on the species and the location they live in. Crows in North America are known to live over 30 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 Crow or Sparrow migratory birds?

Crows are partially migratory. Those in southern hemisphere are mostly residents. While some birds migrate short distances during winters, some others stay put even in frigid temperatures. Some of them may migrate to breed and some may travel to escape increased urbanization.

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 Crow and Sparrow fly in flocks?

A flock of Crows is called a murder. Crows are sociable birds. They live in groups of varying sizes and always roost in flocks. The birds also have their own families consisting of two to 15 members. Different families communicate and cooperate with each other.

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.

Are Crow or Sparrow protected?

Are Crow or Sparrow endangered?

Crows are not endangered birds although their numbers are reducing owing to habitat loss, persecution by farmers, and widespread urbanization. The Hawaiian Crow is extinct in the wild. Restoration activities to increase their population is in progress. Similarly, numbers of Mariana Crow are dropping since 1960s with only a few of them remaining now. They are listed as critically endangered. Efforts to conserve them are underway.

Sparrows are not endangered but their numbers are on a steep decline. Factors affecting the population of Sparrows are loss of habitat, scarcity of food, urbanization, radiation from mobile towers, pollution, use of pesticides in farmlands, and hunting.

Can Crow and Sparrow fly?

Crows usually fly along the same lines every day. They are joined by their flocks as they fly for hunting or towards their roosting sites. They can fly at a speed of 30-60 miles an hour. During migration, some species travel up to 1,740 miles.

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. On the ground, Sparrows are commonly seen hopping. They jump forward and backward for scraping mud, leaves, or grass with their toes and search for food underneath.

Can Crow and Sparrow swim?

Crows are not waterbirds. They do not have webbed feet and their body structure does not allow them to swim. They may be able to float on shallow waters by flapping their wings.

Sparrows are not regular swimmers. However, they can swim fast to escape from danger. Some species like the House Sparrow can even swim under water. Sparrows regularly bathe in water, sometimes even in a puddle. They wiggle in water to loosen up the dirt on their feathers and to control body temperature.

Mating patterns among Crow and Sparrow

Crows reach sexual maturity when they are two to four years old. The mating displays generally take place on the ground. The male bird ruffles his feathers and makes bowing movements while facing the female. He also makes soft coos to attract her attention. Most partners share their mating territories with their children from previous breeding seasons. The female usually lays two to six eggs in a clutch. The eggs hatch after about 18 days.

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.
