How Baby Kiwis in Virginia Will Help Preserve an Ancient Maori Tradition

At the Smithsonian's world-class breeding center, conservationists are working to preserve a beloved New Zealand bird and culture.

Five years ago, Kathy Brader was letting a friend help her feed the kiwis聽at the in Front Royal, Virginia, when she noticed him studying a few of the molted feathers. The man, a visitor from New Zealand and ex-police officer of Maori descent, had taken up weaving in retirement and was learning to make聽kahu-kiwi cloaks from the birds鈥 quills鈥攁 cultural tradition. After receiving a special permit, Brader allowed him to take a few back home.聽

Endemic聽to New Zealand and the symbol of the country, kiwis聽hold a special place in Maori . Special ceremonies honoring the bird were聽held聽before kiwi hunts, and their聽hides and feathers would then be used to create聽elaborate robes鈥攃alled聽迟补辞苍补驳补听(迟谤别补蝉耻谤别蝉)鈥that were worn in weddings, tribal gatherings, and even into battle. While the Maori were careful to moderate their hunting, kiwi populations took a hit聽as聽European explorers聽killed them聽for their skins, which fetched hefty prices at early museums. Today, all five species聽聽in New Zealand聽due to invasive predators and lowland development.

Brader has spent much of her life fighting to reverse that history. She鈥檚 been at the forefront of kiwi conservation for 29 years, working on cutting-edge ways to care for captive populations and expand the global gene pool.聽This spring and summer,聽Brader and her team from a breeding pair聽donated to the Smithsonian by the New Zealand government. The mates were聽the first to leave the island in two decades, and were聽blessed by the Maori before departure.聽

Getting the couple to produce chicks, however, was a six-year endeavor. At a glance, kiwis might look dorky and affable, but they鈥檙e secretive and finicky when it comes to mating. To make matters more difficult, Ngati Hine Tahi, the male kiwi, had a vice: He really enjoyed a good meal. The weight of the father is vital to successfully rearing a chick鈥攊f it鈥檚 too heavy, it won鈥檛 be able to fertilize the egg. Brader and her team found that each time their pair tried to breed, Tahi spent more time eating his partner鈥檚 food than actually mating. At his heaviest, he was nearly seven pounds鈥攖wice the ideal size.

To correct Tahi鈥檚 bad habit, the staff designed a personalized feeder for his mate, Ngati Hine Rua. Female kiwis have longer beaks than their male counterparts; by lengthening Rua's feeding tube, they were able to keep the extra rations out of Tahi鈥檚 reach. This resulted in a fertilized egg, which the staff gave to another male to sit on for 30 days (Tahi was too inexperienced, and he needed to maintain his weight to make more babies). It was then moved into a tightly controlled incubator and monitored closely until hatching. Two more eggs and chicks came soon after.

The birth of even one kiwi is a big victory for conservationists. But for the Maori, there鈥檚 even more聽reason to celebrate.

After Brader聽first found out聽that聽islanders have a way of recycling聽kiwi quills, she聽requested clearance from the Department of Conservation in New Zealand and U.S. customs agencies聽to create a 鈥渇eather pipeline鈥 of sorts between the Smithsonian and the . 鈥淚 really understood the spiritual connection," Brader says. "The [kahu-kiwi] are handed down, so it鈥檚 not like everyone gets a kiwi cloak." 聽Along with establishing the pipeline, she also asked other zoos聽with聽captive-breeding programs to collect fallen feathers and send them to her. Once she collects聽a nice little heap, she boxes them up and ships聽them on a trans-Pacific journey. Over the years the feather program聽has flourished, and soon, Rua and聽Tahi's聽offspring will also be able to聽contribute.聽

Brader still remembers the first feathers that she聽routed聽to聽New Zealand鈥攖hey're now聽part of her own聽mini kahu-kiwi. The ex-police officer,聽Patarika Whihongi, combined them with聽the mementos聽from his visit, and gifted them back to her.聽The cloak is a symbol of聽Brader's best聽intentions for the pipeline: saving聽a peculiar group of avians,聽weaving together聽two distant cultures,聽and forging a new tradition.
