Webb Auction House, which is in charge of the auction, said that a feather of the long-extinct new Zealand gray butterfly bird (H) set a record price of 46521 new Zealand dollars (about 205874 yuan), making it the most expensive feather ever in the world.

H was last confirmed to be seen in the early 20th century, and its feathers previously sold for as much as 8400 new Zealand dollars (approximately 37173 yuan).

As a member of the wybird family, H was cherished by many and ultimately proved fatal to the species.

For Maori, the bird’s feathers are a symbol of lofty status, and its unique white feathers are used for ceremonial headdresses. Only those in the main ranks are allowed to wear H feathers on their hair, or entire skins on their ears, according to the new Zealand Museum.

The auction house said the feathers were often exchanged for other valuables or given as gifts to show friendship and respect.

European new Zealand people have also begun to regard H as a symbol of prestige. According to the museum, they use the animal’s feathers as fashion accessories and install padded H’s as decoration in wealthy homes.

The museum explained that in the 19th century, Maori and European hunters killed the bird in large numbers and sold its skin to collectors and fashion merchants.

According to reports, in 1901, the Duke and Duchess of York were photographed wearing H feathers in their hats while traveling in new Zealand, and the bird’s deadly popularity further increased.

People are a little crazy, everyone wants an H feather.

In the early 20th century, scientists tried to protect the remaining H, but failed. According to the museum, the government planned to transport the birds to offshore islands, but those who collected the birds sold them as dead specimens, adding that it was more valuable than keeping them alive.

The auction house said all potential buyers must provide a permit from the new Zealand Department of Culture and Heritage before Monday’s auction. As an important national item, feathers can only be purchased by registered collectors and cannot be exported without permission from the Ministry of Health. (Reporter Wang Yuehang)
