Many animals have become extinct in the last 100 years. Today, there are many remarkable animals is facing such fate. There are many reasons why these animals are gone, and others are pushed to extinction; among these are the loss of genetic variation, the loss of habitat, and other threats, especially humans.
Humans have driven already a considerable number of plants and animals to extinction for the past 100 years. These fascinating animals that no longer exist can now be seen only in documents, fossils, old photos, museums, and history books.
By the year 2100, researchers have predicted that the number of 558 mammals will become extinct. This will happen if there’s no improvement and further conservation efforts.
See the 12 list of animals that have become extinct in the last 100 years, and find out the causes that lead them to extinction over time.

List of Animals That Have Become Extinct in the Last 100 Years
1. Paradise parrot
It is among the animals that no longer live and exist; the parrot species is formerly found in the meandering river valleys, with eucalypt woods, including continuous native grasses in eastern Australia. Paradise parrot was small that had a length of 27 to 30 inches.
This remarkable bird has a crimson scapular and a long tail; a male Paradise parrot has a vivid red forehead and an ebony crown on its head. The underbody of this species comes with an emerald-green to a turquoise hue. It has a wonderful upper wing earthy brown hue and a vivid blue-tinted underwing.
Sadly, it has not been spotted since 1928. According to the International Union for the Conservation of Nature (IUCN), the reason it went extinct is due to a mixture of severe drought, predation, loss of habitat, the cutting of eucalyptus trees, and the overgrazing of farm animals.
Most of the cause is by a human. The unique parrot species is now tragically can only be seen in textbooks and documents.

2. Passenger pigeon
This bird species, which was once found in large numbers soaring over the skies of North America and was considered to be among the most populous birds, but is now extinct.
The passenger pigeon, also known as the Ectopistes migratorius scientifically, has been gone from the earth for more than a century. It used to be one of the most common birds in North America, and it still is.
However, the migratory bird was far larger than the mourning dove and the Old World turtledove. It has a pinkish body, a blue-gray head, and a longer tail than the average cat. It can grow up to 32cm in length and fly at speeds of up to 60 mph.
The native Americans depended on passenger pigeons for food that added to the species population fall. When Europeans arrived in North America, hunting for these pigeons became rampant.
The human-induced hunting of passenger pigeons has played a significant role in the slowing of the species’ population and its near extinction and other factors that have contributed to the species’ decline.
Years of hunting, habitat degradation, and predation have resulted in the mass extinction of this species.
The fact that this species is no longer able to fly freely in the skies is a tragedy. Still, it leaves a wonderful legacy to humanity in the form of raising awareness and igniting a conservation movement for various species.

3. Sicilian Wolf
Several local grey wolf packs have seen significant declines in population or have even gone extinct for various reasons like the loss of its habitat.
Among these local grey wolves are the wolf population that previously existed in Sicily, known as the Sicilian Wolf. Once, this wolf species thrived on the largest island in the Mediterranean Sea until it was destroyed and eventually became extinct.
Although this distinct subspecies of the gray Wolf is endemic to the Siberian steppes, it is essentially identical to the Wolf’s in Italy except that it has a lighter tawny-colored coat and the dark band throughout its forelimbs either missing or just barely marked, as is the case with the Italian Wolf.
Because of human activity, the extinction of the Sicilian Wolf has occurred. According to a study, humans are responsible for wolf extinction because of its voracious appetite for livestock owned by farmers.
In addition, it is believed that the environmental crisis on the island and the environmental disaster on the island has contributed to the population’s decline and eventual extinction on the island.

4. Japanese sea lion
The Japanese sea lion, which used to be able to freely swim in the ocean and bask by the bay in the Japanese Archipelago and on the Korean Peninsula, is now a living memory. This animal is not found in the water but rather in textbooks, museums, and legends, because it is one of the animals that have gone extinct in the previous 100 years.
Before 2003, it was regarded to be a subspecies of the California sea lion, which it is linked to.
It was a part of the eared seal group, which other sea Lions. They differed from real seals in that they had little permanent earflaps and rear flippers that could be twisted to face forward. The Black sea lion and its other names demonstrate that adult males had a dark coloration, and females had a paler shade, comparable to brown.
According to estimates, 30,000 to 50,000 Japanese sea lions roamed freely throughout the shore, but they are now gone. The amazing mammal is on the verge of extinction as a result of several factors.
This species did not have any natural enemies, with the exception of humans, who hunted them for their skins, whiskers, and internal organs. Japanese sea lions were also captured to sell them to circuses. Aside from that, it is a victim of fishing-related persecution and harvesting.

5. Bubal hartebeest
There are a variety of extinct species on the planet. One of these species is the bubal antelope, which is also known as the bubal hartebeest or the bubal hartebeest antelope. In the previous century, this intriguing species, which was last seen roaming freely in the northern reaches of the Saharan Desert, has been extinct.
The bubal hartebeest was described as having a body that was consistently sandy in color. It bears a patch of grayish color on each side of its muzzle above its nostrils, which is distinctive. When viewed from the front, it measured 43 inches at the shoulder and had horns that were shaped like a ‘U’.
During the nineteenth century, the subspecies suffered a significant fall, particularly during the French conquest and extermination of this species. It is mostly due to overhunting on humans’ part that this subspecies of hartebeest is being driven to extinction.

6. Tasmanian tiger
Native throughout Australia’s large continent, including the islands of Tasmania and in the country of New Guinea, the Tasmanian tiger was formerly observed strolling as a free-ranging animal that is now among the animals that no longer exist.
The Tasmanian Tiger, also known as the Thylacine and Tasmanian Wolf, has an intriguing property in that it has 15 to 20 distinctive dark stripes throughout its back from shoulders to tail, which is visible from the shoulders to tail.
In addition to the black eye, there are two small brown triangles with orange fur on the outside that sit opposite it. It has a robust jaw with a considerable number of teeth (46 in total).
The Thylacine was primarily active at night or in the early morning hours, but it was also active during the day. The Thylacine hunted alone or in couples, and it did it primarily at night. Kangaroos, smaller animals, and birds make up the bulk of its food.
European colonists and farmers hunted down the Tasmanian tiger because they feared it would prey on their sheep, resulting in the extinction of the endangered species. Another factor contributing to its demise is competition for food with Dingo.
Today, no Tasmanian tigers are roaming the Australian plains; instead, they can only be seen in museums and in the literature about the animal. The final movie made of a live Tasmanian tiger was taken in 1936 at the Hobart Zoo, which is the only place where the species is still living. The tiger died in 1936.

7. Heath hen
Once abundant along the east coast of the United States, this animal is now extinct. It is believed that the Heath hen went extinct in the last 100 years for a variety of causes. It is a subspecies of the larger prairie chicken that is only found on Martha’s Vineyard, which is located in the United States.
Because of its morphological traits, this species is quite similar to the Greater Prairie Chicken of the Plains in appearance. Even though the Heath hen is slightly smaller in size, with a length that can reach roughly 17 inches and a weight of approximately two pounds,
Heath Hens were quite prevalent in their natural habitat during colonial times, but because they were gallinaceous birds, settlers heavily hunted for food to supplement their diet.
Aside from hunting, wildfires and a shift in the location of this chicken’s population were factors in its dwindling population. Following the extinction of the heath hen species in 1933, Booming Ben is the last known surviving member of the species’ lineage.

8. The Golden Toad
The Golden Toad once live in a great population in Monteverde Cloud Forest, and now it is one of the animals that have become extinct in the last 100 years. It is a notable frog with a vivid burnt-yellow coloration that is almost identical to gold, which is where its name comes from.
For most of its existence, the species remained underground, surfacing only for a few days in order to reproduce. Seeing these frogs must have been a fantastic sight to behold due to their bright gold color, but it is now only available in textbooks and on the internet because they will never longer be found in the forest as well as in years ahead.
The little toad was last observed in 1989 in a Costa Rican rainforest, and it was officially extinct in 1994 after not being discovered. In the decrease of the toad’s population, it is suspected that Chytridiomycosis, which is a lethal skin illness and an infectious disease that kills amphibians, was among the cause of the extinction.
Due to a lack of suitable habitat, global warming, and a limited population, the species’ numbers have steadily declined over the years, and it has now been unfortunately proclaimed extinct.

9. Carolina parakeet
From southern New York and Wisconsin all the way to the Gulf of Mexico, its brilliant feathers of the only species of parrot native to the eastern United States and formerly flew in were found in old forests along rivers from southern New York and Wisconsin to the Gulf of Mexico.
On February 21, 1918, a male named Incas died within a year of his mate Lady Jane at the Cincinnati Zoological Garden, officially bringing the species to an end. The last wild living of this bird was killed in Florida’s Okeechobee County, and the last captive pair perished at the Cincinnati Zoological Garden in 1918.
The vivid feathers of the Carolina Parakeet, which come in a variety of colors, including green to yellow and red, were highly regarded as ornaments for women’s hats in the early 90s. As a result, the number of people hunting and killing this rare species increases while its population decreases.
Natural catastrophes such as fires and floods, in addition to human hunting, could have fragmented the birds’ habitat, resulting in extinction. Aside from that, deadly diseases have decimated the population of these once-prolific birds.

10. Caspian tiger
Among the animals that have become extinct in the last 100 years is the Caspian Tiger. It is a magnificent tiger that used to inhabit the lands of eastern Turkey, the Caspian Sea, and northern Iran and is now extinct. A variety knows the tiger of names, including the Persian tiger and Turan tiger, among others.
Like any other tiger, the Caspian tiger was distinguished by the sheer size of its legs, which were significantly longer than those of other members of the large cat family, emphasizing the animal’s immense size even further. Even though it featured the characteristic striped tiger stripes, its real color was very different from that of other tiger species.
During the nineteenth century, according to National Geographic, the Russian Army was ordered to eliminate the tigers as part of an agricultural development initiative. This drives these big cats to extinction, and they are now only remembered through stories, memories, and historical documentation.

11. Helena Darter
St. Helena Darter is a species of fish found only in St. Helena, a volcanic island in the Atlantic. It is a species of dragonfly that is now considered extinct, belonging to the Libellulidae family.
There are a lot of factors that have contributed to the dragonfly’s extinction. There are no specific threats to this insect; however, habitat degradation is the most likely threat to this species survival.
Following the island’s colonization by Europeans in the late sixteenth century, the island’s natural ecology has been severely altered, resulting in the extinction of the island’s original vegetation.
The extinction of the African clawed frog was also aided by the introduction of new and invasive species by humans in its habitat. The final sighting of St. Helena Darter was in 1963, marking its extinction from the face of the earth.

12. Guam flying fox
Guam is a tropical island in the Pacific Ocean, namely the tropical islands of the Marianas, which include Guam. According to the International Union for Conservation of Nature, the conservation status of these bats has been proclaimed Extinct since they have not been sighted since the 1970s.
It has been 100 years since the last of these tiny fruit bats was killed by hunters, and they have not been reliably sighted since then.
These are little herbivores that can grow up to 14-15 cm in length and weighs only 152g. They are herbivores that eat plants.
When this species was still living, it faced the most serious challenges from predators and humans alike. It has a hairy appearance and a color ranging from brownish-yellow to gray or dark brown. They are also nocturnal that is most active at night.
Humans have played a significant role in the extinction of this flying fox species, both by introducing humans into its habitat and by hunting these flying foxes for consumption.
