Differences between Crow and Egret
Crow and Egret are two classes of birds that belong to the Corvidae and Ardeidae 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.
Egrets are birds that symbolise purity and strength. They belong to the species of Herons. These birds have white plumage that were used in earlier times for dress and trade. Egrets differ from other species of Herons by their mating displays and the pure white plumes they develop in the breeding season.
Where are Crow and Egret 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.
Egrets live close to wetlands, be it fresh or salt. You can find them near seas, rivers, marshes, ponds, and thick forests. They were originally found in Europe, Asia, and Africa but have later spread across the world. As they cannot survive colder weather, they are not distributed in Antarctica and the Arctic.
What do Crow and Egret 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.
Egrets are carnivores that source their feeds generally from water systems. So, their diet mostly includes fish, water insects, frogs, snakes, and crustaceans. However, Egrets sometimes also hunt on land and eat insects, grasshoppers, and rodents.

Size of Crow and Egret?
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.. Egrets are smaller than Herons. They are a little less than three feet tall and have wings that measure 1.3-1.7 metres.
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 An adult Egret usually weighs 1.1-3.3 pounds.
Where do Crow and Egret 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.
Egrets generally build large and messy nests in their colonies that even consist of birds of other species. The nests are usually constructed on shrubs or lowly trees, typically 10-40 feet from the ground. It is mostly the male egret that establishes the nesting area by creating a nest platform. Both the male and female egrets incubate the eggs for a period of around 24 days.
How long do Crow and Egret 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.
Lifespan of an Egret is up to 15 years in the wild. The younger ones could face high mortality due to climate, migration, predators, and siblicide. The oldest Great Egret lived for almost 23 years in the state of Ohio.
Are Crow or Egret 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.
Egrets become residents in warmer locations. However, in regions where they cannot withstand the cold, they tend to migrate after the breeding season. Migration usually happens from Europe to Africa and south Asia and from northern parts of the USA to central and southern America.
Do Crow and Egret 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 Egrets is known by different names, such as colony, siege, skewer, wedge, and congregation. Egrets are sociable and hunt in flocks. But they can also remain isolated. They generally gather during sunsets and roost in colonies.
Are Crow or Egret 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.
Governments across the world have taken measures to protect Egrets under wildlife conservation and migratory bird laws. Egrets are protected in various countries like the USA, UK, China, Taiwan, China, Russia, India, and France.
Are Crow or Egret 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.
The population of Egrets dwindled to near extinction in the 19th century owing to devious hunting of the birds for their plumes. However, introduction of protection and conservation laws have helped in resurgence of their population. Egrets can now be commonly found in wetlands and coasts across the world. They are not an endangered species.
Can Crow and Egret 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.
Egrets start flying when they are six to seven weeks old. They are dynamic flyers with an ability to cover 25 miles in an hour. They tuck their neck in and hold their legs freely in flight. They are capable of flying long distances during migration.
Can Crow and Egret 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.
Egrets are generally wading birds. They rarely swim to catch their preys. Further, they have non-webbed feet that makes swimming difficult for them.
Mating patterns among Crow and Egret
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.
Egrets acquire heightened beauty during the breeding season – the reason for which bird watchers yearn to catch a glimpse of them during this time. The birds start mating when they are two or three years old. Each breeding season of the year, the male egret selects a nesting area where it builds a nest platform. It then displays its special long white plumes to find a mate for courtship. Egrets generally breed in their colonies and seldom in solitary pairs.
When is the mating season for Crow and Egret ?
The mating season for Crows is usually March-July. It varies slightly in different continents.
The mating season for Egrets is usually October-December in the southern hemisphere and March-May in the northern hemisphere. They breed only once a year.
Do Crow and Egret 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.
Egrets are monogamous during each breeding season. However, they may not stay with the same partner every year. They are known to have multiple partners in their lifetime.
How do Crow and Egret 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.
Egrets sleep at night while standing on one foot in water to sense vibrations from predators. They keep their heads retracted under a wing. They generally roost in flocks to stay safe from attacks.
Can Crow and Egret 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.
Egrets used to be eaten in earlier times in some parts of Africa. However, they no longer can be hunted for their meat. It is illegal and will invite hefty fines.
Can you hunt Crow or Egret?
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.
Egrets were hunted ruthlessly until late 19th century for their plumes. This led to their near extinction. Nevertheless, new anti-hunting, conservation, and migratory laws adopted across the world have saved the species. Egrets are widespread and a common sight now.
Can you feed Crow or Egret?
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.
Feeding wild animals and birds in public places is not permitted in places like USA, Singapore, and Dubai. In captivity, Egrets can be fed with fish, eggs, insects, earthworms, and meat.
