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

Lyall’s Wren

The tragic story of the Lyall’s wren Like the dodo, the Lyall’s wren, also known als Stephens Island wren, stands as one of the most well-known examples of bird species extinction, as the circumstances of its disappearance are both poignant and tragic. The story of the Lyall’s wren is often

dodo reconstruction in National Museum of Natural History in Paris, France

This reconstruction of a dodo is the result of interpretative work based on historical and scientific research: testimonies, representations, and bones. There is no taxidermized specimen of the species. The bird was created by the artist Camille Renversade and realized in collaboration with the taxidermy workshops of the Museum.

Dodo

Dead as a dodo The dodo, a relative of pigeons (Columbidae), is perhaps the most famous example of a species driven to extinction by humans. Representations of the bird in literature and art are common, such as in the third chapter of the children’s book Alice in Wonderland (1865) by

Tongatapu Rail

The only specimen is now lost Many bird species from the past were described based on a single specimen, which is now lost. One such example is the Tongatapu rail. Historical reports and descriptions of this bird species from the rail family (Rallidae) remain, based on observations and collections made

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

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 have been unsuccessful. However, many scientists believe that it may still survive to this day. The IUCN also lists the bird, belonging to the

Similar to Amsterdam wigeon: Auckland duck (Anas aucklandica)

According to the ornithologists Olson and Jouventin, the extinct Amsterdam wigeon is similar to the Auckland duck (Anas aucklandica; see picture), which still exists today and is also flightless. The picture by John Gerrard Keulemans appeared in the book Buller's Birds of New Zealand (1988). (© John Gerrard Keulemans, Public domain, via Wikimedia Commons)

Amsterdam wigeon

Amsterdam duck was barely larger than a thrush Both Amsterdam Island and Saint Paul are more than 3,000 kilometers away from continents. Yet, or perhaps because of this, the islands were often visited by early sailors and their accompanying animals, leading to the extinction of all endemic birds there before

North Island Giant Moa

The second largest moa species This moa species inhabited bush, grass, and dune lands, as well as forests on New Zealand’s North Island. The North Island giant moa is considered the second largest moa species. The largest species is the South Island giant moa, which was endemic to New Zealand’s

The bush moa is the smallest moa species known to date. It was only slightly larger than today's turkeys and reached a weight of around 30 kilograms. The flightless bird died out around 500 to 600 years ago with the colonisation 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
