The American Museum of Natural History houses a small wooden doll, nestled within its vast Native American halls, that holds sacred significance for the tribes whose ancestral lands once encompassed Manhattan.

For more than six months now, the ceremonial Ohtas, or Doll Being, has been hidden from view after the museum and others nationally took dramatic steps to board up or paper over exhibits in response to new federal rules requiring institutions to return sacred or culturally significant items to tribes – or at least to obtain consent to display or study them.

The doll, also called Nahneetis, is just one of some 1,800 items museum officials say they’re reviewing as they work to comply with the requirements while also eyeing a broader overhaul of the more than half-century-old exhibits.

But some tribal leaders remain skeptical, saying museums have not acted swiftly enough. The new rules, after all, were prompted by years of complaints from tribes that hundreds of thousands of items that should have been returned under the federal Native American Graves Protection and Repatriation Act of 1990 remain in museum custody.

"If things move slowly, then address that," said Joe Baker, a Manhattan resident and member of the Delaware Tribe of Indians, descendants of the Lenape people European traders encountered more than 400 years ago. The collections are part of our story, part of our family. We need them home. We need them close."

The New York museum’s president, Sean Decatur, promised tribes would hear from officials soon. He said that, over the past few months, staff have been reexamining the displayed objects in order to begin contacting tribal communities.

The museum also plans to open a small exhibit in the fall incorporating Native American voices and explaining the history of the closed halls, why changes are being made and what the future holds, he said.

Museum officials envision a total overhaul of the closed Eastern Woodlands and Great Plains halls – akin to the five-year, $19 million renovation of its Northwest Coast Hall, completed in 2022 in close collaboration with tribes, Decatur added.

"The ultimate aim is to make sure we’re getting the stories right," he said.

Lance Gumbs, vice chairperson of the Shinnecock Indian Nation, a federally recognized tribe in New York’s Hamptons, said he worries about losing representation of local tribes in public institutions, with exhibit closures likely stretching into years.

He noted that the American Museum of Natural History is one of New York’s major tourism draws and a mainstay for generations of area students learning about the region’s tribes.

He suggests museums use replicas made by Native peoples so that sensitive cultural items aren’t physically on display.

"I don’t think tribes want to have our history written out of museums," Gumbs said. There’s got to be a better way than using artifacts that were literally stolen out of gravesites."

Gordon Yellowman, who heads the Department of Language and Culture for the Cheyenne and Arapaho Tribes, said museums should look to create more digital and virtual exhibits.

He said the tribes in Oklahoma will seek from the New York museum a sketchbook by the Cheyenne warrior Little Finger Nail containing his drawings and illustrations from battle.

The book, which is in storage and not on display, was plucked from his body after he and other tribe members were killed by U.S. soldiers in Nebraska in 1879.

"These drawings weren’t just made because they were beautiful," Yellowman said. "They were made to show the actual history of the Cheyenne and Arapaho people."

Institutions elsewhere are taking other approaches.

In Chicago, the Field Museum has established a Center for Repatriation after covering up several cases in its halls dedicated to ancient America and the peoples of the coastal Northwest and Arctic.

The museum has also since returned four items to tribes, with another three pending, through efforts that were underway before the new regulations, according to spokesperson Bridgette Russell.

At the Cleveland Museum in Ohio, a case displaying artifacts from the Tlingit people in Alaska has been reopened after their leadership gave consent, according to Todd Mesek, the museum’s spokesperson. However, two other displays remain covered up, with one containing funerary objects from the ancient Southwest to be redone with a different topic and materials.

And at Harvard, the Peabody Museum’s North American Indian hall reopened in February after about 15% of its roughly 350 items were removed from displays, university spokesperson Nicole Rura said.

Chuck Hoskin, chief of the Cherokee Nation, said he believes many institutions now understand they can no longer treat Indigenous items as "museum curiosities" from "peoples that no longer exist."

The leader of the tribe in Oklahoma said he visited the Peabody this year after the university reached out about returning hair clippings collected in the early 1930s from hundreds of Indigenous children, including Cherokees, forced to assimilate in the notorious Indian boarding schools.

"The fact that we’re in a position to sit down with Harvard and have a really meaningful conversation, that’s progress for the country," he said.

As for Baker, he wants the Ohtas returned to their tribe. He said the ceremonial doll should never have been on display, especially arranged as it was among wooden bowls, spoons and other everyday items.

Museum officials say discussions with tribal representatives began in 2021 and will continue, even though the doll technically does not fall under federal regulations because it's associated with a tribe outside the U.S., the Munsee-Delaware Nation in Ontario.

"It has a spirit. It’s a living being," Baker said. "So if you think about it being hung on a wall all these years in a static case, suffocating for lack of air, it’s just horrific, really."
