Differences between Crow and Starling
Crow and Starling are two classes of birds that belong to the Corvidae and Sturnidae 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.
Starlings are resplendent song birds that are short and stout. There are about 110 species of Starlings across the globe. The birds have short tails and flat wings. Their bills are slender, pointed, and yellow. They are fierce, aggressive, greedy, and smart birds. The plumage of these birds is a sparkling purple green during summers, while they turn brown with white spots in winters. The feet are strong and bright orange or brown in color. Starlings are known as noisy birds. They can produce a plethora of sounds, like chirping, chattering, whistling, and rattling. Further, they can imitate the calls of other birds, human voices and words, mobile ringtones, car honks, and several other sounds.
Where are Crow and Starling 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.
Starlings are commonly seen in agricultural lands, parks, gardens, grasslands, and cities. The bird is native to Europe and Asia. Having been introduced to other parts of the world, they can also be found in South Africa, Australia, New Zealand, North America, Canada, and Caribbean Islands.
What do Crow and Starling 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.
Starlings are omnivores. They forage mainly on the ground. So, they chiefly eat larvae, worms, insects, beetles, grasshoppers, snails, seeds, nuts, and fruits.

Size of Crow and Starling?
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.. Starlings are tiny birds. They are about seven to nine inches long with a wingspan of 12-17 inches. Nias Hill Myna is the largest in the family with a length of nearly 14 inches.
Thick-billed Raven is the largest among crow species. It weighs 2.5-3.3 pounds. On the other hand, the weight of Jackdaw Crow, the smallest Crow, is eight ounces. while Starlings weigh about 2.04-3.5 ounces. Nias Hill Myna weighs the heaviest among all Starling species at 14 ounces.
Where do Crow and Starling 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.
Starlings make their nests in scattered colonies. The nests, made of grass and twigs, are mostly built in holes and cavities of trees and buildings. They are usually located 10 to 30 feet above the ground. The eggs are oval and a soft green or blue in color. The female bird largely incubates the eggs for about 12 days. The chicks get fed by both parents in the nest for three weeks, after which they fledge.
How long do Crow and Starling 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.
The average lifespan of Starlings is two to five years in the wild. They live longer in captivity. The wild birds roost in groups and migrate in winters to extend their lifespan. The life expectancy of Starlings is affected by high mortality of baby birds, scarcity of food, hunting, and predator attacks. The oldest lived starling was nearly 23 years old. It was found in the wild in Denmark.
Are Crow or Starling 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.
Migration of Starlings depends on their geography. The ones living high up in the northern hemisphere move southward during winters. In the UK, they relocate from the west coast to the east coast. The birds from North America and Canada usually move to the USA. The Asian species travel from northeastern regions towards the south and west. Some species also stop over in the Middle East and North Africa.
Do Crow and Starling 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 flock of Starlings is called murmuration. The birds are extremely gregarious and live in large flocks comprising of several hundreds to thousands of birds. Flocking helps the birds to stay safe from predators and keep themselves warm at night. It also gives them an opportunity to communicate with each other about sources of food.
Are Crow or Starling protected?
Crows are protected in many countries under various schemes and laws for wildlife conservation and protection of migratory birds. Harming Crows or their nests is a punishable offence in these places. However, in countries like Canada there is no law to protect Crows.
Starlings are not protected in major parts of the world. Only a few countries like the UK and Canada have laws prohibiting harming and hunting of the birds. Starlings are largely considered as pests because they destroy crops like grapes, strawberries, apples, and figs besides many other fruits and seeds. They also consume water and feed kept for livestock, while contaminating the feed with their droppings. To save their crops and livestock from the nuisance, farmers kill Starlings by shooting and poisoning them.
Are Crow or Starling 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.
Starlings are not endangered birds. However, their population is falling drastically in several parts of the world, especially the UK.
Can Crow and Starling 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.
The flight of the Starling murmuration is a sight to behold. The birds fly in massive groups that could even consist of over 10,000 birds. The swarm could include other Starling species and other bird species as well. Starlings fly in different patterns to maintain fluid formation. As the birds swoop and swirl, the shift in pattern is seamless, synchronous, and swift. The avian behavior is a result of extreme coordination. Each bird always aligns itself to the immediate seven birds around it. The murmuration is intended to keep the flock safe and intimidate the predators with the enormity. It also helps the birds to conserve energy during long flights. Starlings are known to be able to fly at speeds of 37-50 miles an hour. During migration, they travel up to 620-930 miles in a day.
Can Crow and Starling 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.
Starlings are not regular swimmers although they can manage to swim. They regularly bathe in water to keep their plumage clean and reduce body temperature in summers.
Mating patterns among Crow and Starling
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.
At the onset of the breeding season, the male Starling birds find a nesting location and prepare the base of the nest using grass and leaves. He then perches at the nesting site, singing and waving with his wings to attract the female. The male and female are said to have paired when they partner to complete the construction of the nest and carry out other activities together. The partners raise one to two broods each year. Each clutch typically consists of three to six eggs.
When is the mating season for Crow and Starling ?
The mating season for Crows is usually March-July. It varies slightly in different continents.
The mating season for Starlings depends on the geography. Typically, it is during April-June. Starlings could make breeding attempts more than once a year.
Do Crow and Starling mate for life?
Crows are monogamous. They mate with the same partner each year. Only in the case of death or indisposition of one partner does the other seek a different mate.
Starlings are monogamous during each breeding season. Nevertheless, the male could look for a mate when his partner is incubating the eggs. Female birds who have not mated during the season could be aggressive towards those who are mating the second time.
How do Crow and Starling sleep?
Crows usually roost in colonies. They sleep on top of tree while standing up. The birds generally sleep when the sun sets and wake up little before sunrise.
Starlings choose roosting sites that are safe from predators and shielded from harsh weather. They tend to sleep more during winters. They sleep for less than five hours in summers and around three hours on full moon nights. When the flocks gather at roosting sites, they perform avian stunts and spend time in communication before resting for the night.
Can Crow and Starling be eaten?
Crows are eaten in some cultures. Native Americans and Lithuanians eat them in frenzy. Eating Crow meat is permitted in many countries across the world.
Starlings are widely consumed by people. Their meat is cooked in different ways. They are a regular meal in countries like France. Killing the birds for meat is allowed in several nations.
Can you hunt Crow or Starling?
Crows are hunted for different reasons, such as for sport and meat. They are also killed by farmers for destroying their crops. The birds are not protected everywhere. Countries like the USA allow killing of Crows with a permit or outside of the nesting season.
Starlings are not protected in most countries. They are hunted for sport and meat. They are also hunted and killed for the destruction they cause to agricultural lands and livestock.
Can you feed Crow or Starling?
Feeding Crows in public is discouraged in places like Singapore, Canada, and Dubai. However, feeding Crows is a ritualistic practise in some cultures of south Asia. In captivity, Crows are given worms, mice, eggs, and meat.
Starlings eat worms, berries, and fruits. At agricultural lands and livestock farms, people often have feeding stations for Starlings to prevent them from attacking crops and the feeds reserved for livestock. The birds are fed with peanuts, sunflower seeds, mealworms, egg powder, and leafy greens.
