The world’s most expensive feather is a glossy black, white-tipped tail feather in excellent condition that originated from a now-extinct species of New Zealand wattlebird known as the huia (Heteralocha acutirostris). On 20 May 2024, it sold at Webb’s Auction House for NZ$46,522 (£22,409; US$28,417), including buyer’s premium. It had initially been expected to fetch c. NZ$3,000 but went on to break the previous record (also a huia feather, sold at Webb’s in 2010) by some 450%.
Restricted to New Zealand’s North Island, the huia was last definitively observed in 1907, though a few unconfirmed sightings were reported for at least two decades beyond that (and possibly even as recently as the early 1960s). This species was sacred to the Māori people, whose chiefs and their families often wore its tail feathers in their head-dresses. Its extinction is poorly understood, but habitat destruction and over-hunting, coupled with predation by introduced rats and infection by those non-native mammals’ parasites, all likely played a part.
A feature that distinguished the huia was the unparalleled degree of sexual dimorphism exhibited in the beak between males and females. Whereas that of the male was short, stout, straight and sharply pointed at its tip, that of the female was long, slender, and downward-curved, the two shapes having evolved to fulfil two very different functions. The male’s was used to chisel out grubs (especially those of Prionoplus reticularis, a longhorn beetle commonly called the huhu) from decaying wood like a woodpecker does, and the female’s was used to secure grubs from deep woody crevices that her mate’s shorter beak could not reach. Until recently, it was thought that the possession of a sexually dimorphic beak was unique to the huia, but it is now known that a second, unrelated species of vanished bird, the Réunion crested starling (Fregilupus varius), extinct since 1837, also sported such a beak, but not to so pronounced a degree as in the huia.
