The TanagerExpedition was a series of five biological surveys of the Northwestern Hawaiian Islands conducted in partnership between the Bureau of Biological Survey and the Bishop Museum, with the assistance of the United States Navy. Four expeditions occurred from April to August 1923, and a fifth in July 1924. Led by Lieutenant Commander Samuel Wilder King on the minesweeper USS Tanager (AM-5), and Alexander Wetmore directing the team of scientists, the expedition studied the plant [1] animal life, and geology of the central Pacific islands. Noted members of the team include archaeologist Kenneth Emory and herpetologist Chapman Grant.
The expedition began with the goal of exterminating domestic rabbits that had been introduced to Laysan island by the guano industry in 1902. Since that time, the rabbits had devoured Laysan's vegetation and led to the extinction of several endemic species. The rabbits were eventually eliminated on Laysan, and the crew witnessed the extinction of the Laysan honeycreeper (ʻapapane). Throughout the expedition, new species were discovered and named, and unique specimens were captured and returned to laboratories for further study. Over 100 archaeological sites were found, including ancient religious sites and prehistoric settlements on Nihoa and Necker Island.
The first expedition departed Honolulu on April 4, 1923, and returned on May 4. [2] The team visited the island of Laysan, Pearl and Hermes Atoll, Midway Atoll, and Kure Atoll. When they spent a month on Laysan studying the endemic Laysan honeycreeper, a violent and sudden storm ravaged the island. After the storm, the crew concluded that the last three specimens of the honeycreeper had been killed.
The second expedition departed Honolulu on May 10. [2] The team visited the island of Laysan, the French Frigate Shoals and the Pearl and Hermes Atoll.
The third expedition departed Honolulu on June 9. [2] The team visited the islands of Necker, Nihoa, and the French Frigate Shoals. An attempt was also made to visit Kaula. Tanager arrived at Nihoa on June 10 and dropped off scientists for a ten-day visit and moved on to Necker the following day to drop off a second team. Both teams used radio to keep in constant communication between the two islands. [3] On Nihoa, botanist Edward Leonard Caum collected the first specimen of Amaranthus brownii and Alexander Wetmore discovered the Nihoa millerbird and named it Acrocephalus familiaris kingi, in honor of Captain Samuel Wilder King. [4] Evidence of an ancient settlement on Nihoa was discovered, along with platforms, terraces, and human remains. [5]
On June 22, the Tanager arrived in the French Frigate Shoals and remained for six days, completing the first comprehensive survey of the atoll. [6] The expedition returned to Honolulu on July 1. [2]
The fourth expedition consisted of two teams, with the first departing Honolulu on July 7. [2] Destinations included Johnston Atoll and Wake Island. The first team left on the Whippoorwill (AM-35), which made the first survey of Johnston Island in the 20th century. Aerial survey and mapping flights over Johnston were conducted with a Douglas DT-2 floatplane carried on her fantail, which was hoisted into the water for take off. Two destroyer convoys accompanied the expedition from Honolulu. The Tanager (AM-5) left Honolulu on July 16 and joined up with the Whippoorwill to complete the survey. From July 27 to August 5, the expedition surveyed Wake Island and named its islets: The southwest islet was named after Charles Wilkes who had led the United States Exploring Expedition in 1841 and determined the location of Wake Island. The northwest islet was named after Titian Peale, the chief naturalist for the 1841 expedition.
The fifth expedition visited Nihoa and Necker Island in 1924. [7] Archaeologist Kenneth P. Emory of the Bishop Museum cleared out 60 sites on Nihoa and collected and cataloged artifacts. [5] The expedition visited Necker from July 14–17.

In 1990, the U.S. congress passed the Native American Graves Protection and Repatriation Act which requires federal agencies and institutions that receive federal funding to return Native American cultural items and human remains to their people. In the 1990s, Hui Mālama (Hui Mālama I Na Kūpuna O Hawaiʻi Nei), a Native Hawaiian group, spent two years petitioning the United States Fish and Wildlife Service for the release of the bones (iwi) from seven Hawaiian skeletons originally taken from Nihoa and Necker Island by the Tanager Expedition in 1924. Although the bones were owned by the USFWS, the Bishop Museum acted as custodian. [8] The bones were finally released to the group, and in November, 1997, Hui Mālama chartered a yacht and travelled to Nihoa and Necker to rebury the remains. [9]
The Bernice Pauahi Bishop Museum, designated the Hawaiʻi State Museum of Natural and Cultural History, is a museum of history and science in the historic Kalihi district of Honolulu on the Hawaiian island of Oʻahu. Founded in 1889, it is the largest museum in Hawaiʻi and has the world's largest collection of Polynesian cultural artifacts and natural history specimens. Besides the comprehensive exhibits of Hawaiian cultural material, the museum's total holding of natural history specimens exceeds 24 million, of which the entomological collection alone represents more than 13.5 million specimens. The Index Herbariorum code assigned to Herbarium Pacificum of this museum is BISH and this abbreviation is used when citing housed herbarium specimens.
Necker Island is a small island in the Northwestern Hawaiian Islands. It is located at 23°34′30″N164°42′01″W in the Pacific Ocean, 430 miles northwest of Honolulu, Hawaii, 155 miles northwest of Nihoa, and 8 miles north of the Tropic of Cancer. It is part of the state of Hawaii in the United States. It contains important prehistoric archaeological sites of the Hawaiian culture and is part of the Hawaiian Islands National Wildlife Refuge within the Papahānaumokuākea Marine National Monument.
Nihoa, also known as Bird Island or Moku Manu, is the tallest of ten islands and atolls in the uninhabited Northwestern Hawaiian Islands (NWHI). The island is located at the southern end of the NWHI chain, 296 km (160 nmi) southeast of Necker Island. Nihoa is the closest NWHI in proximity to the eight main windward Hawaiian Islands at approximately 240 km (130 nmi) northwest of the island of Kauaʻi. The island has two peaks, 272 m (892 ft) Miller's Peak in the west, and 259 m (850 ft) Tanager Peak in the east. Nihoa's area is about 171 acres (0.69 km2) and is surrounded by a 142,000-acre (57,000 ha) coral reef. Its jagged outline gives the island its name, Nīhoa, which is Hawaiian for "toothed, serrated".
The Northwestern Hawaiian Islands also known as the Leeward Hawaiian Islands, are a series of islands and atolls located northwest of Kauai and Niʻihau in the Hawaiian island chain. Politically, these islands are part of Honolulu County in the U.S. state of Hawaii, with the exception of Midway Atoll. Midway Atoll is a territory distinct from the State of Hawaii, and is classified as one of the United States Minor Outlying Islands. The United States Census Bureau designates this area, excluding Midway Atoll, as Census Tract 114.98 of Honolulu County. The total land area of these islands is 3.1075 square miles. With the exception of Nihoa, all these islands lie north of the Tropic of Cancer, making them the only islands in Hawaii situated outside the tropics.
Laysan is one of the Northwestern Hawaiian Islands, located 808 nautical miles northwest of Honolulu. It has one land mass of 1,016 acres (4.11 km2), about 1 by 1+1⁄2 miles in size. It is an atoll of sorts, although the land completely surrounds Laysen Lake some 2.4 m (7.9 ft) above sea level that has a salinity approximately three times greater than the ocean. Laysan's Hawaiian name, Kauō, means 'egg'.
The Laysan finch is a species of Hawaiian honeycreeper, that is endemic to the Northwestern Hawaiian Islands. It is one of four remaining finch-billed Hawaiian honeycreepers and is closely related to the smaller Nihoa finch. The Laysan finch is named for Laysan, the island to which it was endemic on its discovery. It was subsequently introduced to a few other atolls, and its historical range included some of the main islands.
Pritchardia remota, the Nihoa pritchardia, Nihoa fan palm, or Loulu, is a species of palm endemic on the island of Nihoa, Hawaiʻi, and later transplanted to the island of Laysan. It is a smaller tree than most other species of Pritchardia, typically reaching only 4–5 metres (13–16 ft) tall and with a trunk diameter of 15 centimetres (5.9 in). It is the only type of tree on the island and used to be abundant. In 1885 a wildfire ravaged the island, destroying most of the palms. Only about 700 of these trees remain, making the species endangered but numbers are slowly increasing. The palm is being cultivated in botanical gardens.
The Laysan millerbird was a subspecies of the millerbird, similar in appearance to the remaining subspecies, the Nihoa millerbird. Its dorsal side was brown, and its belly was grayish. Its name derives from its favorite food, several species of moths of the genus Agrotis commonly referred to as "millers".
Schiedea verticillata, known as the Devils Slide schiedea or Nihoa carnation, is an endangered species of plant in the family Caryophyllaceae, endemic to the island of Nihoa in the Northwestern Hawaiian Islands, where it was discovered in 1923 by the Tanager Expedition. It has been listed as endangered since 1996.
Amaranthus brownii was an annual herb in the family Amaranthaceae. The plant was found only on the small island of Nihoa in the Northwestern Hawaiian Islands, growing on rocky outcrops at altitudes of 120–215 m (394–705 ft). It was one of nine species of Amaranthus in the Hawaiian Islands, as well as the only endemic Hawaiian species of the genus. It is now considered extinct.
Sesbania tomentosa, commonly known as Oahu riverhemp and ʻōhai, is an endangered species of plant in the pea family, Fabaceae, that is endemic to the main Hawaiian Islands as well as Nihoa and Necker Island. It inhabits low shrublands and, rarely, dry forests, at elevations from sea level to 2,500 ft (760 m). Associated native plant species include akiʻaki, ilima, naupaka kahakai, and pili. Off-road vehicles, wildfires, grazing, and alien species competition have destroyed their habitat on the main islands, but they are still quite common on Nihoa and Necker. At least 2000 specimens grow on Nihoa, while there are far less on Necker.
Maximilian Joseph August Schlemmer, known as the "King of Laysan," was a German immigrant to the United States who settled in Hawaii and spent fifteen years from 1894 to 1915 living with his family on the Hawaiian island of Laysan as superintendent of a guano mining operation. Schlemmer was interested in the birdlife of the island and made several studies which provide information on historic bird populations. However, Schlemmer and his family introduced rabbits to Laysan, leading to the extinction of the Laysan rail and Laysan millerbird and permanently changing the island's ecology in the early 20th century. A biography of Schlemmer was written by his grandson, Tom Unger.
The Laysan honeycreeper, also known as the Laysan ʻapapane or Laysan honeyeater, is an extinct species of finch that was endemic to the island of Laysan in the Northwestern Hawaiian Islands. The bird was first recorded in 1828 and in 1892 received its scientific name from Walter Rothschild, who placed it in the genus Himatione along with the ʻapapane. The specific name, fraithii, refers to George D. Freeth, the self-appointed governor of Laysan, but was misspelled. Rothschild attempted to emend it to freethi in a later publication. This was accepted by most subsequent authors throughout the 20th century, and the bird was also considered a subspecies of the ʻapapane, as H. sanguinea freethii, for most of this time. By the 21st century, after further research, the original name was reinstated and it was considered a full species again. As a Hawaiian honeycreeper, a grouping within the finch subfamily Carduelinae, its ancestors are thought to have come from Asia.
Kenneth Pike Emory was an American anthropologist who played a key role in shaping modern anthropology in Oceania. In the tradition of A. L. Kroeber and other pioneering anthropologists who trained him, Emory's works span all four major fields of anthropology: archaeology, physical anthropology, ethnography, and linguistics. With fellow scientists Gerrit P. Wilder, Honolulu botanist, and Mrs. Wilder, historian; Dr. Armstrong Sperry and Dr. Stanley Ball, he was part of the Bishop Museum scientific research party who explored the South Pacific on the schooner Kaimiloa.
The Mangarevan expedition of 1934 was a scientific expedition to investigate the natural history of the farthest southeastern islands of Polynesia, including Mangareva. It was a comprehensive natural history expedition of a kind more common during the previous century.
Eucyclotoma albomacula is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. It was first described by E. Alison Kay in 1979 and is distinguished by a single spiral keel on each whorl with axial white stripes; the species name (albomacula) is derived from the Latin albo (white) and macula.
The Bayard Dominick expedition was a 1920 scientific expedition to the Pacific islands of Polynesia, with four teams sent to compile archaeological and anthropological surveys of the Marquesas, Tonga, Austral Islands, and Hawaiʻi.
Erling Christophersen was a Norwegian botanist, geographer and diplomat. He participated in and led several notable scientific expeditions in the 20th century, including the fifth Tanager Expedition (1924) to Nihoa and Necker Island and the Norwegian Scientific Expedition to Tristan da Cunha (1937–1938).
The Laysan fan palm is a not formally described, extinct species of palm most likely in the genus Pritchardia. Endemic to the island of Laysan, it had become extinct by 1896.
