Prehistoric animals varied in size over many different time periods. Most of the largest animals lived millions of years ago during the Jurassic and Cretaceous periods. The Earth is 4.543 billion years old and is home to many animals of all shapes and sizes. In this article, we’ll discuss the giant bird known as the “elephant bird.” This animal is the largest bird that ever lived. It weighs 1,600 pounds. Stands 10 feet tall.
With the help of fossils and knowledge of modern animals, scientists are able to learn about animals that went extinct thousands of years ago. You can discover the approximate size, habitat, and even diet of past animals. While some information may be limited, there are many ways to learn about extinct species. Let’s take a look at the largest birds that ever lived, and what to know about them.

The elephant bird has been described as a very large flightless bird with ostrich-like features. These birds once lived among humans, so there are folktales and even written descriptions of the species. The first complete description of the species was given in the 19th century by the French zoologist Isidore Geoffroy Saint-Hilaire. Remains of this animal are plentiful due to their relatively late extinction.
Fossil remains of elephant birds suggest that the species had relatively small wings, making it incapable of flight. They have two thick, long legs with three-toed feet and a long neck with a conical beak. Despite their long legs, these birds were likely to be slow due to their weight. Their size and speed make them easy to track and hunt.
More than a dozen species of elephant birds have been described, although the validity of most of these species is still debated. There are currently four recognized species; black crown bird, Great Hermit, muller birdand titan. Each species has an average height of about 9.5 to 10 feet, while weight varies.It is believed that V. Titan A maximum weight of 1,900 lbs was achieved.both pheasant Up to a maximum of approximately 1,200 lbs.

Elephant Bird Diet and Habitat
Although these birds are large and appear to prey on smaller creatures, elephant birds are actually herbivores. Studies of smaller birds that resemble elephant birds have led researchers to conclude that the species’ diet may be the same. Their diet consists mainly of low-lying fruits native to their tropical rainforest homes. Experts believe elephant birds played a key role in dispersing fruit seeds on the island, which helped to grow more fruit plants.
Elephant birds live on the island of Madagascar and are believed to have inhabited more remote parts of the island. They lived in the forests of southern Madagascar before humans migrated to the region. Elephant birds also inhabit open areas, although this is less common. Research has led experts to believe that elephant birds, like their kiwi relatives, were likely nocturnal. Since this species lived on more isolated land, they easily evolved to gigantic sizes. This is due to the lack of mammalian predators and the abundance of lush tropical vegetation.
Fossils and Discoveries
Due to the late history of the extinction of elephant birds, many fossils have been found and examined. Madagascar is notoriously poor in the Cenozoic terrestrial fossil record, so there are basically no fossils from the end of the Cretaceous to the Late Pleistocene. Through studies of the mitochondrial genome in recovered Aepyornis eggshells, it is thought that the bird-like species has existed in Madagascar for more than 27 million years.
So far, there is no evidence that elephant birds live anywhere outside of Madagascar. However, there are claims to have found egg remains in the eastern Canary Islands. While these claims have yet to be proven, if they are correct, it would represent a major biogeographical mystery. Today, the eggs are thought to have come from an extinct species of North African bird.
Two whole eggs were identified as being from the species Great Hermit Found in Western Australia. Since the species does not exist in Australia, it is believed that the eggs were brought to Australia from Madagascar via the Antarctic Circumpolar Current. While they’re definitely not as common as the fossilized remains of the species, about a dozen huge fossilized eggs have been found. Some of the eggs were found intact, with the bones of unhatched elephant birds inside.
human-bird interaction
Carbon dating shows elephant bird species, A. hildebrandti, lived on the island of Madagascar until about 1,560-1,300 years ago. This proves that the species likely lived alongside humans after the island was inhabited. Elephant birds are more likely to inhabit remote areas away from humans. However, there have been articles of people seeing what looked like a giant ostrich, now believed to be an elephant bird.
In 1659, Étienne de Flacourt, the French governor of Madagascar, wrote of a very large bird that inhabited remote areas and laid eggs like an ostrich. The 13th-century Italian traveler Marco Polo wrote that he heard many stories about large birds during his travels in Madagascar. At first, scholars thought Polo was referring to a mythical beast that was said to look like a huge flying eagle-like bird. These are now considered descriptions of the subject bird.
How elephant birds became extinct

Elephant birds are known to have been widely distributed in northern and southern Madagascar. These giant birds are known to have lived among humans for some time until they became extinct. Exactly when they became extinct is unknown, but they are known to have existed at least 1,600 years ago. The cause of the extinction is unknown, but a variety of factors likely played a role in the species’ disappearance.
Fossils of elephant birds with tool marks have been found and date back to about 10,000 BC. However, when humans appeared in Madagascar is unclear, and it is still considered a controversial discovery. It is believed that humans not only hunted these animals to extinction, but also brought diseases to the animals that caused them to die more quickly. Climate and vegetation changes have also been blamed for the extinction as well as habitat loss from deforestation.
animals similar to elephant birds
Today, the ostrich is the largest flightless bird. Throughout Earth’s history, there have been many species of flightless birds, many of which are now extinct. There are about 60 species of flightless birds in existence.
Some species today include:
- penguin
- cassowary
- kiwi fruit
- big titan
- emu
- Falkland Steamed Duck
- kakapo
The dodo is one of the most recently extinct flightless birds. A flightless bird has a walking body and smaller wing bones. It is believed that birds may have evolved flightlessness in predator-free habitats. While there are not many species today, there are many examples of flightless birds throughout Earth’s history.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
