The Birch Bark Canoe Step 3

We recently received a request for a few feathers off of a single specimen of Ivory Gull (Pagophila eburnea) collected north of The Pas in 1926, the only specimen we have of this species. The Ivory Gull is a High Arctic breeder that has made an appearance in Manitoba only about a dozen times in the last 100 years. The species is listed as Endangered in Canada and its populations are declining. A research group is examining levels of mercury and stable isotopes of carbon and nitrogen in feathers to investigate the possible role of heavy metal contamination and changes in foraging behaviour in Ivory Gull decline. The Manitoba Museum specimen is one of only about 150 specimens from Canada in all the museums of North America, and its age makes it particularly valuable for reconstructing historic levels of contamination and isotopes. Who could have predicted the value of this Museum specimen for conservation of the species when it was collected those many years ago?

By sharing information on Museum rarities with researchers who can pool data from the few specimens available in collections from around the world, we learn more about the biology of the organism, making the specimen more ‘valuable’ in terms of information and helping conservation efforts. The Museum ends up with another story to tell about its collection and about the animals themselves. Science, the Museum, and, most importantly, the animal will all win from this exchange.

Nature generally can be understood through patterns. Unique observations, like a rare gull found north of The Pas in 1926, are curiosities, but can’t contribute very much to the bigger picture as an isolated event. Even the proverbial apple clunking onto Newton’s head, though important as a unique event, only becomes truly valuable when its act of falling towards Earth can be generalized to explain why other things also fall.

This helps to explain why the Museum has, when possible, more than one example of a species, and continues to grow collections through active collecting. Just as a single letter is more as a part of a word, or a word is more meaningful when put into a sentence, a specimen becomes more in the context of a collection. A particular specimen does have value in and of itself as a record of occurrence in a single place at a single moment (called a voucher), or sometimes even has monetary value. But several specimens from different places collected at different times provide a more complete story of species variability, distribution, biology, and, as in the case of Ivory Gull mercury levels, how these might have changed over time and space. Each individual provides a data point, and an important one, but the real value comes from the collection as a whole. And a new specimen added to the collection today, while not necessarily individually significant right now, might be so 100 years from now, just as the Ivory Gull specimen collected in 1926 is valuable today.

Richard Fortey (a paleontologist at The Natural History Museum, London) suggested that natural history museums are the archives of the Earth, an apt metaphor. Through their collections, museums document individual “events” as specimens, which together tell the story of how our natural world changes over time. The Manitoba Museum plays this critical role as natural history archive for the province. Specimens old and new are together a feather in our collective cap.

Just outside my office on the 4th floor of the Museum is a big, hairy outlaw that can stare anybody down. It’s the mounted head of one of the original ‘outlaw buffalo’ of the Pablo/Allard herd of Plains Bison (Bison bison bison), the most significant of the private herds purchased by the Canadian government that helped to bring these magnificent animals back from the brink of extinction.

Michel Pablo rounded up his bison in Montana, loaded them onto boxcars and sent over 700 to Canada between 1907 and 1914. However, there were a few individuals that were too wild and managed to escape. In early 1911, in what was billed by the The New York Times in January that year as “the last big buffalo hunt in the history of the world,” Pablo hunted down and shot these ‘outlaw’ bison. The metal plaque on the Museum hallway head clearly identifies it as a member of Pablo’s ‘outlaw’ herd.

I mentioned the Museum bison head mount to a volunteer in Geology and Paleontology, Dr. Jim Burns, who has a fascination with Winnipeg history. He brought to my attention a photograph he had researched that showed 11 bison heads lined up on Main Street in 1911, apparently from that famous last hunt by Pablo (see Burns, J.A. 2010. Edward Darbey, taxidermy, and the last buffaloes. Manitoba History, 63:40-41). It seems that a number of these animals had made their way to a well-respected Winnipeg taxidermist, Edward Darbey. Born in St. Thomas, Ontario in 1872, Darbey came to Winnipeg at the age of 15. In 1898 he purchased the taxidermy shop on Main Street that is the backdrop to the bison skulls in the photo. By 1902, Darbey had been appointed as the “Official Taxidermist of the Manitoba Government,” an odd title by today’s standards, but one that made sense at the time when animal mounts were frequently used to decorate public buildings.

The Pablo bison were hunted in early 1911, the bison head and taxidermy shop photo was dated by Dr. Burns to around mid-1911, and there is record of a Winnipeg auction of bison head mounts and capes in late November, 1911. According to the plaque on our Museum mount, it became property of the City of Winnipeg in 1912, a reasonable date to link it with the somewhat gruesome Main Street display.

So our big, hairy ‘outlaw’ bison mount is 100 years old this winter. This could be considered a depressing anniversary of the killing of some of the last ‘wild’ bison in North America. But for me, the old head commemorates the beginning of an incredible conservation story, the salvation of our provincial emblem and, just perhaps, an altered attitude of society towards the world around us.
