Differences between Crow and Heron

Crow and Heron 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.

Herons are intelligent birds of medium to large size. They are a symbol of beauty with long legs and neck. They are wonderful aviators that can fly at a speed of nearly 30 miles an hour. The Heron family includes several species such as Egrets and Bitterns.

Where are Crow and Heron 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.

Herons live near freshwater and coasts. While most species are found in the tropics, they do exist in lowland and alpine areas. They can be seen in all parts of the world, except Antarctica.

What do Crow and Heron 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.

Herons are carnivores that feed on the boundaries of rivers, seas, ponds, and lakes. They are named as one of the smartest birds for their skills in advanced feeding habits and procurement of food. They usually feed on aquatic animals such as fish, frogs, reptiles, insects, eels, and crustaceans. In winters, when these water animals move down to deeper waters, herons manage to hunt smaller birds, rabbits, and squirrels on the land.

Size of Crow and Heron?

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.. Herons are generally about three feet tall. They have broad wings, usually twice their body size. The wings spread out to measure 5.5-6.5 feet.

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 Herons usually weigh 4.6-7.3 pounds. The males are bigger and weigh more than the females.

Where do Crow and Heron 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.

Herons construct their nests close to feeding areas like wetlands and lakes. The nests are built on tall trees to stay safe from predators. It is the female that builds the nest from twigs, roots, and dead grass gathered by the male. The female generally lays three to five eggs that have an incubation period of around 25 days. Once the eggs hatch, both female and male partners participate in getting food for their young ones.

How long do Crow and Heron 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 life expectancy of a Heron is five years in the wild. Some young ones do not survive after the first year due to scarcity of food, while some of them fall prey to predators. The longest surviving great wild blue heron is known to have lived for 23 years.

Are Crow or Heron 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.

Herons are very mobile, however their migration depends on where they are. They prefer warmer climates, so tend to migrate in winters. After the breeding season, the birds explore new feeding areas and migrate alone or in small groups of 12 during the night. The Grey Herons are mostly residential and stay put in Britain and other parts of Europe. On the other hand, the Great Blue Herons migrate from March to May every year, flying around 7,000 feet above sea level.

Do Crow and Heron 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 Herons is called a siege or colony. Herons are mostly solitary birds – they migrate alone or in small groups. However, during the breeding season in spring and summer, they live in colonies. This practise helps them to nest together and protect their young ones from predators.

Are Crow or Heron 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.

Herons are an important part of the ecosystem at wetlands. Therefore, they are protected birds under the law of the USA, Great Britain, Ireland, France, and many other countries. This means that killing or trying to kill a Heron is a punishable offence.

Are Crow or Heron 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.

Herons are not endangered, however their population may be reducing owing to destruction of their natural habitats and scarcity of food. Meanwhile, some Heron species like Humblot’s Heron and White-bellied Heron are labelled as critically endangered.

Can Crow and Heron 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.

Herons have a wide wingspan that allows them to fly at speeds of nearly 30 miles an hour. Further, they have 12 rectrices that help them maneuver while flying. The bird is known to cover up to 2,500 miles in six days. Their wings open up wide, their long legs trail freely, while their neck retracts into an S shape during flight.

Can Crow and Heron 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.

Herons are not basically water birds. They find their catch on the margins of lakes, rivers, and shores – or hover on water to dive in and catch a fish. They have slightly webbed feet, so they may be able to swim occasionally.

Mating patterns among Crow and Heron

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.

Herons start mating when they are about three years old. During the breeding season, the male and female birds undergo color changes and develop the nuptial plumage. Herons engage in breeding once a year, atop tall trees in case of larger herons and in bushes for smaller ones. The male and female Herons engage in Circle Fight, Greeting Ceremony, and courtship displays for several days to abate their natural aggression, after which the male demonstrates a gesture of acceptance by offering a stick for the nest to the female.

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.

Herons go through extensive mating rituals, which enhance the bond between the male and female. They stay together for an entire breeding season and sometimes for a few years – however not for life. The birds change partners about four times in their lifetime.

How do Crow and Heron 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.

During the day, Herons rest in peaceful and protected places with their neck bent. Sometimes they also sleep standing in water so that vibrations caused by the entry of predators will wake them up. At night, they sleep on high trees to keep themselves safe from the predators on land.

Can Crow and Heron 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.
