Our lives are persistently affected by these wonderful creatures, with over 10.000 different species of birds worldwide.
But as the human population grows, these helpless creatures that make our lives wonderful are struggling to survive.
While some are celebrated for their immense size, like the large sized birds, others are vanishing before our eyes.
The majority of such threats come from excessive hunting, deforestation, pollution, and land transformation.
Nearly 13% of birds on Earth are on the brink of extinction.
As an awareness initiative, here are the top 10 rarest birds in the world:
10. Philippine eagle
The Philippine eagle is one of the largest and most powerful eagles in the world. Endemic to the Philippines, the species is threatened by habitat destruction, deforestation, and illegal hunting.
The Philippine eagle lives mainly on four major Philippine islands: Luzon, Samar, Leyte, and Mindanao. Among these, Mindanao has the largest remaining population and the highest number of breeding pairs.
The eagle typically measures between 86 and 102 centimeters (2 ft 10 in to 3 ft 4 in) in length, making it one of the world’s biggest forest eagles.
Studies of museum and natural history specimens suggest that some Philippine eagles in the past may have grown even larger.
Often called the “Monkey-eating Eagle,” the Philippine eagle was originally believed to prey mainly on monkeys, although its diet also includes flying lemurs, snakes, birds, and other small animals.
9. Great Indian bustard
The Great Indian Bustard is one of the rarest birds in the world and is now on the verge of functional extinction. The species population has declined drastically, with only around 150 birds remaining in recent years.
The Great Indian Bustard is mainly found in the Indian states of Rajasthan and Gujarat. However, the population in Gujarat has nearly disappeared, leaving Rajasthan as the primary habitat for the remaining birds.
These birds have traditionally lived in the Thar Desert and surrounding grassland ecosystems for centuries.
Their natural habitat consists of open grasslands and semi-arid regions, which are essential for breeding and survival.
Conservationists warn that habitat destruction, agricultural expansion, wind energy projects, and overhead power transmission lines are major causes of the species’ decline.
Collisions with power lines are considered one of the leading threats to the Great Indian Bustard, causing frequent fatal injuries.
Environmental experts have also criticized the lack of large-scale grassland conservation efforts and insufficient measures to reduce bird deaths caused by power infrastructure.
Rapid industrial development and changing land use patterns continue to put pressure on the species’ remaining habitat.
The Great Indian Bustard is now considered a symbol of India’s biodiversity crisis and one of the most endangered bird species in the world.
8. Christmas frigatebird
The Christmas frigatebird is a large and lightweight seabird known for its long, narrow wings, brownish-black feathers, and deeply forked tail. The bird has an impressive wingspan of around 2.15 meters (7.1 feet), making it highly adapted for long-distance flight over the ocean.
The male Christmas frigatebird is recognized by its bright red gular sac, which it inflates to attract a mate, along with an egg-shaped white patch on its belly. The female is slightly larger than the male and has white breasts and a white belly.
Christmas frigatebirds can travel vast distances in search of food and are well known for kleptoparasitism, a behavior in which they steal food from other seabirds.
Their strong flying ability allows them to remain airborne for more than a week at a time, giving them access to a wide feeding range across the sea.
These seabirds spend much of their lives over the ocean, feeding mainly on fish and squid collected near the water’s surface.
7. Bali myna
The Bali myna is a lovely, snow-white bird with black tips and a striking sky-blue skin patch surrounding its eyes.
It is probably because of its beauty that this bird depiction is used in the cultural art of the Indonesian Island of Bali.
In a small area of Bali, an island less than Rhode Island, you find the Bali myna or Bali starling.
Even if they are found only in a small part of the world, they seem to have all they need to prosper, the Bali mynas, also known as Bali starlings.
It’s fascinating to note that in Indonesia, this bird can be found elsewhere, but some Jalak Bali have been discovered in Lombok once.
Unfortunately, there is not a single bird of Bali Myna in its indigenous place of origin. Less than 100 Jalak Bali have left the wild to date, elsewhere.
6. Blue-eyed ground dove
The Blue-eyed Ground-Dove was considered to be extinct hardly five years ago.
Some wildlife researchers found 11 to 12 individuals in the wild after 75 years without a confirmed sighting.
In Brazil, a country where many rare species survive, the Blue-eyed Ground-Dove is one of the rare birds with a confirmed population of sixteen individuals in the wild.
Named after its bright blue eyes, this small dove has spots on its wings and the rest of its rich tawny and rufous plumage.
The ornithologist Rafael Bessa found that the species was extinct until 2015, making a discovery of a lifetime.
5. Kakapo
Kākāpō is the world’s only flightless parrot and one of the rarest birds on Earth. Native to New Zealand, the kākāpō is a large, nocturnal parrot known for its plump body, owl-like appearance, and unique behavior. It is also called the “owl parrot.”
At the other end of the size spectrum, smallest birds in the world face their own survival challenges.
The kākāpō is the heaviest parrot species in the world and is critically endangered. Only around 211 birds remain in the wild, with the surviving population restricted to a few predator-free islands off the coast of New Zealand.
Before humans arrived in New Zealand, kākāpōs were common throughout the country’s forests. However, the introduction of mammals such as rats, cats, and stoats severely reduced their population by hunting eggs, chicks, and adult birds.
By the 1990s, the wild population had dropped to fewer than 50 birds, pushing the species to the brink of extinction.
Despite conservation success in recent years, the kākāpō remains one of the world’s most endangered bird species and continues to require constant protection to avoid extinction.
4. California condor
The California condor is the largest bird in North America and one of the most endangered birds in the world.
Known for its massive black wings and impressive gliding ability, the California condor can travel long distances in search of food.
California condors mainly feed on dead animals such as deer, pigs, cattle, sea lions, whales, and other large mammals.
Their sharp eyesight, intelligence, and ability to soar for hours without flapping make them one of the most remarkable scavenger birds in the wild.
Thousands of California Condors once lived in the wild across the western USA and in Mexico.
However, as human settlements expanded, condors faced major threats from hunting, poisoning, habitat disturbance, and egg theft. Their natural food sources, including elk and antelope, also declined significantly.
By the late 20th century, the remaining condors survived mainly in the mountains of southern California and relied on scavenging livestock carcasses and other dead animals. In the 1980s, the wild population dropped to only 22 birds, pushing the species close to extinction.
Conservation and captive breeding programs later helped increase the population.
Despite conservation progress, lead poisoning from bullet fragments in animal carcasses remains one of the biggest long-term threats to the survival of the California condor.
3. New Caledonian owlet-nightjar
The New Caledonian owlet-nightjar is a rare nocturnal bird related to nightjars and swifts.
It has gray-brown and black patterned plumage, a long, slightly rounded tail, short, rounded wings, and strong legs. Its exact call remains unknown, although similar birds in the same family produce whistling and churring sounds.
According to the International Union for Conservation of Nature (IUCN), the New Caledonian owlet-nightjar faces an extremely high risk of extinction and is considered one of the rarest birds in the world.
The species was first identified in 1880 after a single specimen was collected in New Caledonia. For many years afterward, no confirmed sightings were recorded, leading researchers to believe the bird had become extinct.
However, the species was rediscovered in 1998 when a possible sighting of the New Caledonian owlet-nightjar was reported.
This discovery changed its conservation status and renewed scientific interest in the bird.
Today, very little is known about the species.
Only one confirmed sighting, a few unverified reports, and two preserved museum specimens located in Liverpool and Italy are known to exist.
The lack of data and sightings makes the New Caledonian owlet-nightjar one of the most mysterious and critically endangered birds on Earth.
2. Giant ibis
The giant ibis is the national bird of Cambodia and one of the rarest birds in the world. Although the species is critically endangered, conservation efforts are underway to prevent its extinction and restore its population.
The Giant ibis is a large and striking bird known for being the biggest member of the ibis family. It is also the only surviving member of its genus, making it especially important for wildlife conservation and biodiversity.
Despite ongoing protection efforts, the population of the Giant ibis continues to decline due to habitat destruction, hunting, and environmental changes.
Conservation experts warn that the species remains at high risk unless stronger and more successful protection measures are implemented.
Today, only around 200 mature Giant ibises remain in the wild, with the total population estimated at roughly 300 adults and young birds combined. The species is mainly found in parts of Cambodia, Vietnam, and Laos.
1. Madagascan pochard
The Madagascar pochard is a small brown diving duck native to Madagascar. With its sandy-brown feathers, elegant appearance, and bright beady eyes, it is considered one of the rarest ducks in the world.
For many years, scientists believed the Madagascar pochard had become extinct. However, in 2006, a small surviving population was rediscovered in a remote area of northern Madagascar, making it one of the most remarkable bird rediscoveries in recent history.
The remaining ducks were found living in a deep volcanic crater lake far from their original wetland habitat. Although the species survived there, the environment was not ideal for breeding and feeding.
The depth and temperature of the lake made it difficult for young ducklings to find food and survive, unlike the shallow marshes and wetlands where the species originally thrived.
Habitat loss and environmental changes pushed the Madagascar pochard to the brink of extinction.
The world’s rarest birds face growing threats from habitat destruction, climate change, hunting, and human activity.
From the Kākāpō to the Philippine eagle, these endangered bird species highlight the urgent need for wildlife conservation and habitat protection.
Without stronger global conservation efforts, many rare birds could disappear forever.
