“Bird extinctions after European discovery were extensive and are now well documented; however, native Polynesians caused extinctions of an even greater magnitude. Fossil evidence shows at least 50% of the original avifauna became extinct after Polynesians arrived in Hawai’i around 400 A.D.”
“Initially, 109 endemic species occurred in the Hawaiian Islands, 35 of which (32%) still survived in 2001; 19 additional taxa (17.5%) were extant in the 18th century, whereas 55 (50.5%) are known only from the fossil and subfossil record.” (Perez)
“In pre-human Hawai‘i, the large land area and extensive coastlines, coupled with a relative absence of predators, provided ample habitat for a spectacular assemblage of seabirds; millions of petrels, albatrosses, shear-waters, terns, and other seabirds populated the islands. These birds were the first to be easily decimated or exterminated by island settlers.”
“After the unwary, flightless, ground- and burrow-nesting seabirds were eliminated, Polynesians devised an astounding variety of techniques for catching forest birds; these bird-hunting practices eventually wreacked havoc also among forest bird populations.”
“The severe past depredations of avifauna appear to have had a lasting negative effect on the Hawaiian forest birds and, as a result, the alarming trend of declining bird populations still continues.”
“Overall, the USA has suffered the most recently recorded bird extinctions (25) on Earth, 84% of which have taken place in Hawai’i.” (Perez)
With respect to post-Contact activities, “[Robert] Perkins, Henry Palmer, Scott Wilson, and George Munro – all were stalking and shooting Hawaiian birds in the 1890s, during the peak of what Alan Ziegler has called the “professional naturalist period” (1870-1900) in Hawaiian history.” (Tummons)
“Although scientific knowledge of the birds of the Hawaiian Islands began with the European discovery of the archipelago in 1778 by Captain James Cook, more than a century elapsed before any serious ornithological exploration of the islands took place.”
“In 1887, Scott Barchard Wilson, with the support and encouragement of Alfred Newton, Professor of Zoology at Magdalene College, Cambridge (England), embarked on a collecting expedition to the Hawaiian Islands, where he stayed until the end of 1888.”
“Descriptions of new species began appearing under Wilson’s name in August 1888, when he was still in the islands, and it has long been my belief that Newton wrote the bulk of everything that was attributed to Wilson and to Wilson and Evans.”
“The new discoveries arriving from the Hawaiian Islands excited the imagination of Newton’s pupil Walter Rothschild, who, using the wealth at his disposal, determined to send out his own collector.”
Lionel Walter [Walter] Rothschild, 2nd Baron Rothschild (the eldest son of Nathan Mayer Rothschild, 1st Baron Rothschild), (born February 8, 1868, London, England—died August 27, 1937, Tring, Buckinghamshire), was a British zoologist who founded the Rothschild Natural History Museum in London. (Britannica)
“His interest in natural history began when he was a child, collecting butterflies, and as a child, Walter knew exactly what he wanted to do when he grew up, announcing at the age of seven, ‘Mama, Papa, I am going to make a museum…’. By the time he was ten, Walter had enough natural history objects to start his first museum, in a garden shed.” (Rothschild Archive)
“He began building a real museum when he came of age in 1889 …. Having come under the influence of renowned ornithologist Alfred Newton while at Cambridge, his interest in birds moved to the fore for many years; entomology and ornithology remained the focuses of his scientific work for the rest of his life.”
“Although Rothschild himself traveled and collected in Europe and North Africa for many years, his work and health concerns limited his range, and beginning while at Cambridge he employed others – explorers, professional collectors, and residents – to collect for him in remote and little-known parts of the world.” (Olson)
“Walter employed around 400 collectors during his lifetime and accumulated specimens from more than 48 different countries, many of which were new to Western science. Collectors sent him animal specimens from around the world. Walter mainly stayed in Tring and focused on carefully studying the creatures he received and describing new species.” (Rothschild Archive)
“He also hired taxidermists, a librarian, and, most importantly, professional scientists to work with him to curate and write up the resulting collections: Ernst Hartert, for birds, from 1892 until his retirement at the age of 70 in 1930; and Karl Jordan for entomology, from 1893 until Rothschild’s death in 1937.”
“In 1890, when Rothschild was 23, he sent a sailor named Henry Palmer to the Sandwich Islands (as the Hawaiian Islands had been named by Captain James Cook in the late 1770s) and most particularly to Laysan, one of the Leeward Islands in the Hawaiian archipelago now part of the Hawaiian Islands Bird Reservation.”
Palmer arrived in the Hawaiian Islands December 1890, with his New Zealander assistant George Munro, who stayed with him until March 1, 1892, when he was replaced by another New Zealander, Ed. (“Ted”) B. Wolstenholme. (Olson)
“His instructions were to collect as many different birds as possible, with special attention to inter-island variation. Palmer spent over two years at the task, from December 1890 to August 1893, and sent almost 2000 specimens back to Tring, including representatives of 15 species previously unknown to Western science and several species which have since become extinct.”
“These specimens formed the basis of Rothschild’s monograph The Avifauna of Laysan and the Neighboring Islands. The work includes a survey of the literature on the birds of Hawaii to that date, as well as a condensed version of Palmer’s collecting diary.” (Olson, Curator of Birds, Smithsonian National Museum of Natural History)
“[Rothschild] built the collections continuously over the decades, until they formed the largest zoological collection ever amassed by a private individual.” (Olson)
“At its largest, the collection included 300,000 bird skins, 200,000 birds’ eggs, 2,250,000 butterflies, and 30,000 beetles, as well as thousands of specimens of mammals, reptiles, and fishes. The bird collection in particular was unparalleled, considered in many ways the finest in the world, and invaluable for the study of geographical variation and other aspects of evolution.” (Olson)
“During his lifetime Walter accumulated: 2,000 mounted mammals, about 2000 mounted birds, 2 million butterflies and moths, 300,000 bird skins, 144 giant tortoises, 200,000 birds’ eggs and 30,000 relevant books.” (Rothschild Archive)
“In spite of his family’s great wealth, the eccentric baron was sometimes short of money. He sold most of his beetles to raise funds for his museum, and in 1931 a personal crisis forced him to sell his bird collection to the American Museum of Natural History in New York City.” (Natural History Museum)
“When he died at 69 in 1937, he left his remaining research collections, the public museum, its contents and the surrounding land to the Natural History Museum in London.”
“His collection is the biggest private natural history collection ever assembled by one person, and the largest bequest of specimens ever received by the Museum. … Today, Museum staff working at Tring look after more than a million bird specimens, nests and eggs. Researchers from around the world travel to Tring to use this important collection.” (Natural History Museum)
