Historical depiction of elephant bird
Historical depiction of Aepyornis maximus. Our knowledge of the elephant birds’ external appearance is incomplete: there are no preserved specimens, only bone finds and eggshells. Reconstructions therefore rely on anatomical inferences and comparisons with modern ratites. (© http://www.50birds.com/gextinct5.htm, Public domain, via Wikimedia Commons)

Aepyornis maximus – the largest elephant bird and the mystery of when it went extinct

There wasn’t just one elephant bird The elephant bird is probably one of the best-known of all extinct birds. Hardly any other animal so strongly embodies gigantism, enigmatic traditions, and the fascination of a world of animals that humans now know only in fragments. But the name already misleads: there

Dodo reconstruction at the National Museum of Natural History in Paris, France
This replica of the dodo is the result of interpretative work based on historical and scientific research: accounts, depictions and bones. No taxidermied specimen of the species exists. The bird was created by the artist Camille Renversade and realised in collaboration with the museum’s taxidermy workshops.

Dodo – Dead as a dodo

The dodo, related to pigeons (Columbidae), is probably the best-known example of an animal species exterminated by humans. References to the bird in literature and painting are common—for example in chapter three of the children’s book Alice in Wonderland (1865) by Lewis Carroll or in the paintings of the Flemish

Truffles (Gallacea scleroderma) and moas

What links extinct moas, colorful truffles, and climate change?

New Zealand, known for its unique wildlife and flora, holds many secrets from the past. One of them was revealed by a recent study in Biology Letters: the extinct upland moas (Megalapteryx didinus) were not only majestic birds, but also played a central role in dispersing colorful, truffle-like fungi such

Stephenschlüpfer
The Lyall’s wren extinct less than ten years after humans settled Stephens Island. It is considered a classic example of the extinction of an island endemic with no natural defense mechanisms against invasive predators. (© Vertebrate Zoology Curator, CC0, via Wikimedia Commons)

Human-Caused Species Loss: Global Impact Far Greater Than Expected

A study published in early October in the journal Science suggests that human-caused species loss has far-reaching consequences that were previously underestimated. The scientists highlight the fact that the extinction of bird species has not only wiped out ecological roles but also billions of years of unique evolutionary history. In

Stephens Island Weevil

From isolated paradise to endangered habitat Stephens Island, a small rocky island in the Cook Strait, is renowned for its unique wildlife. Despite covering only 1.5 square kilometers, the island boasts a remarkable ecosystem that was once home to numerous endemic species, including many land and seabirds. Among its notable

Georg Forster: Image of the Tongatapu rail?

Tongatapu rail

The only specimen is now lost Quite a few bird species of the past were described from only a single specimen that is now lost. One of them is the Tongatapu rail. Of this rail species (family Rallidae), historical reports and descriptions have survived that are based on observations and

Jagd auf Moas
New Zealand’s unique bird life evolved in isolation over millions of years. The image, created at the end of the 19th century, shows a hunting scene of moas. (© Joseph Smit, Public domain, via Wikimedia Commons)

In the Footsteps of Moas: Where New Zealand’s Flightless Birds Find Refuge

The settlement of the Pacific Islands by humans led to rapid waves of extinction for many animal species, whose dynamics are difficult to reconstruct. Among the affected species were the wingless moas, which were only found in New Zealand. These often massive birds went extinct in the 14th or 15th

Himalayan quail (Ophrysia superciliosa) or mountain quail by Gould
Painting of a pair of Himalayan quails by John Gould from 1883. Females are smaller and lighter; males have darker feathers, a white forehead, and white spots near the eyes. The genus name is derived from Ophrys, which refers to the eyebrow. (© John Gould, Public domain, via Wikimedia Commons)

Himalayan Quail

A mysterious bird The Himalayan quail is one of the mysteries of avian fauna. It was last conclusively sighted, in 1876, and all subsequent search expeditions were unsuccessful. Nevertheless, many scientists believe it could have survived to this day. The IUCN still lists the bird from the pheasant family (Phasianidae)

Buschmoa-Genom rekonstruiert (Anomaloptery didiformis)
The bush moa is the smallest moa species known to date. It was only slightly larger than today’s turkeys and weighed around 30 kilograms. The flightless bird went extinct about 500 to 600 years ago with the settlement of New Zealand. (© Auckland Museum, CC BY 4.0, via Wikimedia Commons)

Deciphered Bush Moa genome provides insights into New Zealand’s extinct avian world

A team of evolutionary biologists has reconstructed the nearly complete genome of the bush moa (Anomalopteryx didiformis), a flightless bird from New Zealand that went extinct 500 to 600 years ago. Researchers from Harvard University, East Carolina University, Osaka University, and the University of Toronto sequenced ancient DNA from a

anas aucklandica
According to ornithologists Olson and Jouventin, the extinct Amsterdam duck was similar to the still extant, likewise flightless Auckland teal (Anas aucklandica; see image). The illustration by John Gerrard Keulemans appeared in Buller's Birds of New Zealand (1988). (© John Gerrard Keulemans, Public domain, via Wikimedia Commons)

Amsterdam duck

Barely larger than a thrush Both Amsterdam Island and Saint Paul are more than 3,000 kilometers away from continents. Nevertheless—or perhaps precisely because of this—the two islands were frequently visited by early seafarers and the animals that traveled with them, so that all endemic birds there had already been wiped
