Differences between Bald-Eagle and Heron

Bald-Eagle and Heron are two classes of birds that belong to the Accipitridae and Ardeidae families respectively.

Bald Eagle is a type of Sea Eagle with two sub-species. It is a bird of prey with brown plumage and white tail. The bird is not actually bald, it has white colored feather on its head. It is characterized by yellow eyes, beak, and feet. The beak is hooked and is used for capturing the prey and preening. The bird has four toes and talons on each foot. One of the toes faces backwards and helps in holding the prey with extreme grip. According to scientists, the grip of a Bald Eagle is 10 times stronger than that of an average human’s hand. The bird also has exceptional hearing and vision. Bald Eagle is famous as the national bird of the USA.

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 Bald-Eagle and Heron found?

Bald Eagles live around water sources surrounded by forests. They can be found near rivers, reservoirs, lakes, and coasts. They are native to North America. They exist in Mexico, the USA, Alaska, and Canada.

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 Bald-Eagle and Heron eat?

Bald Eagles chiefly eat fish. They also hunt snakes, turtles, small ducks, gulls, geese, lambs, foxes, dogs, rodents, rabbits, and crabs. These birds are also known to eat dead animals and abduct the prey from other animals.

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 Bald-Eagle and Heron?

When it comes to size, The overall size of a Bald Eagle is 2.8-3.5 feet. It has a wingspan of six to eight feet.. 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.

Bald Eagles are enormous birds. They weigh 7-15 pounds. while Herons usually weigh 4.6-7.3 pounds. The males are bigger and weigh more than the females.

Where do Bald-Eagle and Heron nest?

Bald Eagles build the largest nests among all birds in the world. Known as eyries, these nests are four to five feet wide and about two feet deep. They weight up to one ton. Some nests can be double this size. They are made by interweaving sticks and branches, while soft material like grass, feathers, and moss are used inside. Nests are generally positioned on top of large trees in the vicinity of water sources. The eggs are a pale white and shaped oval. Both partners share the task of incubating the eggs for about 35 days. The young ones fledge when they are eight to 14 weeks 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 Bald-Eagle and Heron live?

The average lifespan of Bald Eagles is 20-30 years in the wild. Their life is threatened by illegal hunting, lead poisoning, electrocution, and loss of habitat. The oldest lived Bald Eagle was 38 years old. It died in 2015 due to collision with a car.

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 Bald-Eagle or Heron migratory birds?

Bald Eagles usually reside in their territories throughout the year. The ones living in Canada and Alaska travel south to spend the winters in central and southern parts of USA.

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 Bald-Eagle and Heron fly in flocks?

A flock of Bald Eagles is called a congregation or convocation. The birds are solitary. In winters, they may roost in groups to keep themselves warm. They fly alone even during migration.

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 Bald-Eagle or Heron protected?

Bald Eagles are protected in the USA under the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act. The laws prohibit harming and killing the birds or owning their body parts. The birds are also protected in Canada.

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 Bald-Eagle or Heron endangered?

The population of Bald Eagles had declining to about 450 nesting pairs in 1960s in the USA. The bird was listed as endangered in 1978. However, the banning of DDT and other conservation efforts have yielded good results. With an increase in the numbers of Bald Eagles to about 4,500 nesting pairs in 1995, the species was re-classified as threatened. With further increase in their population to over 6,300 nesting pairs in 2000, the species has been removed from the endangered and threatened species list.

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 Bald-Eagle and Heron fly?

Bald Eagles fly by soaring high with the use of thermals and wind currents. They manage their speed by altering the position of their wings. During long migration, the birds rarely flap their wings in order to conserve energy. The average flying speed of Bald Eagles is 75-100 miles an hour.

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 Bald-Eagle and Heron swim?

Bald Eagles can swim but seldom do. They are mostly airborne birds. They also dive into water to catch their prey.

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 Bald-Eagle and Heron

Bald Eagles reach sexual maturity when they are four or five years old. During the breeding season, the birds become aggressive to defend their territory. Of their mating rituals, the prominent is the cartwheel courtship flight where the male and female soar high, lock their talons, and fall to the ground in a cartwheel spin. They also chase each other and perform aerial dances. The partners may copulate more than once a day. When the eggs are laid, both male and female take turns to incubate them for 34-36 days. The partners also share the responsibility of feeding and protecting the young ones. The eaglets are ready to fledge when they are about 12 weeks old.

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.

How do Bald-Eagle and Heron sleep?

Bald Eagles roost communally during winters. They sleep on large trees to stay sheltered from severe wind and cold. During the breeding season, they sleep closer to the nests. The birds have a locking mechanism in their legs that allows them to maintain their standing posture while asleep.

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.
