Feather and Bone Connections to American History

by Patrick McShea

Within the Hall of North American Wildlife, a Passenger Pigeon taxidermy mount stands above a handful of other objects in a display case designed to spark viewers’ thoughts about human relationships with other creatures. On a text panel outside the case an eight-word statement serves to direct such thoughts:

Directly and indirectly, people and wildlife are connected.

Because Passenger Pigeons have been extinct for more than a century, reflections involving this native species are necessarily historical. An adjacent tray holding dozens of Passenger Pigeon leg bones excavated from an archaeology site in Pennsylvania’s Huntingdon County provides a helpful starting point for reflective time travel.

The concentration of bones, which date from the years 1400-1600, is evidence of a centuries-long utilization of the birds for food by the Indigenous Peoples who lived in what’s now central Pennsylvania. Passenger Pigeons were once so abundant in eastern North America that flocks darkened the skies for hours when the birds migrated to access seasonal feeding areas and nesting sites.

Sustainable use of the birds by humans did not continue into the 19^th Century. By mid-century, Passenger Pigeons became an unregulated commodity in the rapidly expanding American economy, with the country’s growing railroad network and parallel telegraph system providing unprecedented means for sharing word of flock locations, transporting hunters to those sites, and shipping harvested birds to distant markets.

A summary statement from an exhibit about Passenger Pigeon extinction at another institution, the Milwaukee Public Museum, contains a relevant insight:

The primary factor emerged when pigeon meat was commercialized as a cheap food for slaves and the poor in the 19th century, resulting in hunting on a massive scale.

Recognizing an American slavery facet within what is commonly regarded as a natural history extinction story has never been more important. At a time when there is not consensus about how slavery should be presented as a historical topic in classrooms, the preserved remains of a once common bird have a special role to play.

In the 21^st Century, museum taxidermy mounts from the 19^th Century might serve as focal points for wide ranging discussions between the descendants of people who subsisted on Passenger Pigeon meat because they were enslaved, and those who could purchase little else because they were poor.

The exhibit described above is a component of We Are Nature: A New Natural History, an initiative that encourages a broader and deeper consideration of the human impact on our planet through a series of fifteen interpretive panels placed in and among existing exhibits, as well as a new interactive focal area where visitors are invited to record their thoughts, concerns, and hopes.

Finding Answers: From Museum to Mountains and Back Again

by Patty Dineen

The beautiful wildlife dioramas on the second floor of Carnegie Museum of Natural History have been fascinating visitors for decades. Within the Hall of North American Wildlife, most of these realistic displays feature taxidermy mounts of one or more of the continent’s large charismatic mammals, posed in recreated three-dimensional scenes of appropriate habitat that also feature smaller mammals, birds, insects, and, of course, plants.

Typically, the dioramas don’t display a generic environment, such as say, the Arctic, the mountains, or the desert, but rather, they depict specific places in North America. The key to the “where” of each diorama is the painted background. Most of the wildlife dioramas feature gorgeous and detailed renderings of specific locations in North America such as Kodiak Island in Alaska, the Laurel Highlands of Western Pennsylvania, or the beautiful Hayden Valley in Yellowstone National Park.

Finding the Locations That Inspired the Dioramas

Is it still possible to travel to, and view, the locations featured in these wonderful dioramas? Would those places look the same today as when they inspired artistic rendering as wildlife diorama paintings many decades ago? And first things first, how would you even go about finding the exact locations depicted in any of the dioramas? Let me tell you a brief story of a recent travel adventure that included an attempt to find the specific vantage point in Yellowstone National Park where a view of the park’s namesake river valley was long ago recreated as a painting some 1,700 miles east in Pittsburgh. The diorama in question features four American elk: two males fighting as two females watch the action from the side. The scene is a snapshot of the fall elk rut, the mating season when males compete to gather “harems” of females.

Last fall, as some museum staff made plans for a guided visit to the park, an attempt to locate and stand in the elk diorama vantage point earned a spot on our agenda.

In early October 2021, our group of 21, consisting of museum staff and their travelling companions, flew from Pittsburgh to Bozeman, Montana, and then traveled south by bus through Paradise Valley to Mammoth Hot Springs in Yellowstone National Park. From this location we began three full days of guided exploration of different parts of the 3,472 square mile park, hoping that at some point we might be able to find the “Elk Diorama” location. We were armed with the Elk Diorama label copy – “…a ritualistic bout between bull elk on the edge of the Hayden Valley, overlooking the Yellowstone River, in Yellowstone National Park,” maps of the park, and photos of the museum’s Elk Diorama. When we shared our information and diorama photos with our two professional guides, one recognized the view and said she was pretty sure she knew the location.

Over our three days of exploring the park we saw geysers and other geothermal features; learned about the Yellowstone National Park wolf project and watched wolves through spotting scopes; and enjoyed wildlife sightings of trumpeter swans, black and grizzly bears, elk, pronghorn, bison, ravens, and young cutthroat trout. On the third and final day, we traveled to The Grand Canyon of the Yellowstone and Yellowstone Lake, and then headed back north from Fishing Bridge and into the Hayden Valley. And there it was — not marked on my large map but referred to by our guides as “Grizzly Pullout” — a wide spot at the side of the road where a couple of cars or a small shuttle bus could pull over for a view of the Yellowstone River as it begins a graceful bend away from the Grand Loop Road. There was the distinctive (even on this heavily clouded day) profile of distant mountains to the left and middle, and a hillside sloping up and to the right in the middle distance. Group members took photos and enjoyed what seemed a familiar landscape (many thanks to Suzanne and Andy McLaren for the photos they took at Grizzly Pullout). We then headed back to Mammoth Hot Springs for one last night in the park before heading back to Pittsburgh, the museum, and our beautiful wildlife dioramas.

Big Cats, Big Personalities

You may have heard the phrase “big cat” before. No, it doesn’t refer to a particularly large house cat, but rather to a category of cats. “Big cat” is a term typically used to describe any member of the genus Panthera, though it can mean different things to different people.

Some consider every member of the larger subfamily Pantherinae to be big cats—for example, clouded leopards (genus Neofelis). Sometimes, the phrase “big cat” just refers to any member of the cat family (Felidae) that is large, such as the cougar (genus Puma), the cheetah (genus Acinonyx), and the Eurasian lynx (genus Lynx, species lynx).

Tigers, Lions, Jaguars, Leopards, and Snow Leopards are the extant (or currently living) members. You may be wondering how leopards and snow leopards are members of genus Panthera but clouded leopards are not. Clouded leopards are not true leopards—they branched off into their own genus roughly six million years ago; they are in the larger subfamily of Pantherinae, but not Panthera specifically.

One feature sometimes used to distinguish big cats from other cats is the ability to roar, but that ability is only found in the Panthera genus, not the additional species. Roaring itself is an important vocalization, but it isn’t a surefire way to distinguish what a “big cat” is. For example, snow leopards, in the family Panthera, cannot roar.

So, big cat can mean something different to everyone, but let’s learn a little bit more about each of the cats listed above:

Tigers

Tigers are the largest cat species on the planet! There are several subspecies and they are easily recognized by their orange color with black stripes (though Bengal tigers are occasionally white with black stripes).

They are solitary and territorial animals; cubs (big cat offspring are not called kittens) stay with their mother for 2 years. These cats are found throughout Asia—although they are endangered—and their population is dwindling.

Lions

Lions are a social species of large cats found in the grasslands and savannas of Africa. Males are recognizable by their long hair surrounding their necks, called manes. Lionesses do the hunting for the pride (social group of lions), which is comprised of several adult males, related females, and cubs. These animals are listed as vulnerable, which means they are close to becoming endangered.

Jaguars

Jaguars are the only member of the Panthera genus found in the Americas. Individual cats can be found in the Western United States, but they have had a reduced range in Central and South America since the early 20^th century. They are solitary animals and ambush predators, hunting in tropical and subtropical forests and swamps. They are recognizable by their spots, which are black rosettes with spots in the middle. However, melanistic (or all black) jaguar occasionally appear; these cats are informally known as black panthers—although they are not a separate species—and the phrase “black panther” has been used to describe melanistic leopards as well. Jaguars are near-threatened, which means their numbers are decreasing and their populations are being closely monitored.

Leopards

Leopards have a wide range and are found in Sub-Saharan Africa, in parts of Western and Central Asia and on the Indian subcontinent. They are recognizable by their spots; they look like jaguars with their spotted fur, but leopards are shorter with a smaller head, and their rosette-shaped spots do not have dots in the middle. Leopards are opportunistic hunters, hunting mostly on the ground at night; though in the Serengeti, they are known for attacking prey by leaping from trees. Leopards are listed as vulnerable, meaning they are potentially on their way to the endangered species list.

Snow leopards

Snow leopards live in the mountain regions of Central and South Asia, living at elevations from 3,000 to 4,500 feet. Their fur is whitish grey, with black rosettes, distinguishing them from other leopards which are yellow or brown in color. Snow leopards have large nasal passages which helps warm the cold, dry air they breathe. Their tails are covered thickly with fur and provide fat storage; sleeping snow leopards use their warm tails like blankets to protect their faces when they sleep. They are listed as vulnerable, meaning they may appear on the endangered species list in the future.

Clouded leopards

There are two species of clouded leopards—the mainland clouded leopard (Neofelis nebulosa) and the Sunda clouded leopard (Neofelis diardi). The mainland clouded leopard is found in the Himalayan foothills in Southeast Asia and southern China and the Sunda clouded leopard is found in Borneo and Sumatra. They are considered an evolutionary link between two cat families Pantherinae and Felinae. Their fur is dark grey with a black blotched pattern. Clouded leopards are solitary and hunt by stalking or ambushing prey. They are excellent climbers and use trees as rest sites. Both species of clouded leopards are listed as vulnerable, meaning they can potentially end up on the endangered species list.

Cougar

The cougar (also known as a puma, mountain lion, red tiger, or catamount) is the only cat on this list that you may see in the wild around Pittsburgh; however, their populations are severely reduced in the eastern half of North America. These cats are adaptable to a wide variety of habitats, which is why they are found all throughout North and South America. This wide range is the reason people living in different regions have different names for them. They are ambush predators, preferring to hunt deer, though they will eat insects and rodents. While cougars are large, they are not always the apex (or top) predator and will occasionally give food they caught away to jaguars, grizzly bears, or even alligators! Cougars are listed as least concern, meaning their population is holding steady, though their range has shrunk.

Cheetah

Cheetahs are known for their speed; as the fastest land animal, they are capable of running up to 80 miles per hour! Cheetahs can be found in the Serengeti, Saharan mountain ranges, and in hilly areas of Iran. Cheetahs separate into three kinds of social groups—females with cubs, all-male groups, and solitary males. Females are more likely to travel further distances while males will establish and stay in smaller territories. They are active during the day and spend most of their time hunting for things like impala or springbok. Cheetahs are listed as vulnerable, with one of the main threats being a lack of genetic diversity, which makes it difficult for the species to adapt and evolve over generations, reducing the chance for individual animals to survive.

Eurasian lynx

The Eurasian lynx is found from Europe into Central Asia and Siberia, living in temperate or boreal (snow or Taiga) forests. They have short, red-brown coats, and are more colorful than most animals sharing their habitat. In the winter, their fur grows in thicker and greyer. These cats have relatively long legs and large webbed and furred paws that act like snowshoes, allowing them to walk on top of the snow. They have bobbed (or short) tails, much like one of their cousins you might see around Pittsburgh—the bobcat. They hunt small mammals and birds but will occasionally take down young moose or deer. The Eurasian lynx is listed as least concern, with a stable population.

Bright Flying Mammal

Can you name our region’s most colorful mammal? If the question was asked in front of the museum’s Mammals of Pennsylvania display, many people would choose the red fox near the center of the exhibit’s floor-level row.

Five feet above fox, and just inches from the tip of a raccoon’s tail, a far smaller, but equally bright alternate exists in the form of a gliding eastern red bat.

Eastern red bat — Eastern Red Bat, known to science as Lasiurus borealis

In color, red bat fur ranges from golden brown to bright rusty orange, with males typically sporting brighter shades than females. The bright fur coats of this widespread insect-eating species provide surprisingly effective camouflage when the bats are at rest. Red bats are tree bats, a term that indicates the species’ preference for spending daylight hours roosting within the foliage of deciduous and sometimes evergreen trees.

With wings folded, they hang upside-down from the grip of a single foot, looking, to casual observers, like dead leaves or pine cones.

Red Bats have so far escaped the devastating effects of white-nose syndrome, a fungal disease that since 2007 has caused mortality rates as high as 90% at hibernation sites of many other bat species. Remarkably, on fall migration flights to southern portions of their North American range, red bats have been known to cross long stretches of territory with flocks of migrating birds.

Don’t Overlook the Lichens

Lichens are scenery elements in many museum dioramas. Within the Pronghorn Antelope diorama in the Hall of North American Wildlife, for example, these frequently overlooked organisms coat a foreground boulder with irregular patches of gray, red, and gold.

If you approach this artfully recreated western scene with a little background information about lichens, you might find the colorful cluster of immobile organisms in the bottom right corner just as interesting as the four galloping centerpieces.

Lichens are found on every continent and estimates of their global diversity range from 13,000 to more than 17,000 species. Every lichen is a partnership of two different organisms, a fungus whose tissue provides the physical structure to support a second organism capable of photosynthesis. For most lichens the partner with the solar energy power is some form of green algae. The fungus/algae partnership is a living arrangement in which separate identities fade while combined abilities allow for survival in locations where neither organism could live alone.

Crustose or curst-like lichen and pronghorn antelope scat.

Three distinctive growth forms provide a means for categorizing lichen. The colorful trio sharing the pronghorn antelope diorama are termed “crustose” or crust-like lichens. Lichens with a leaf-like appearance and structure are termed “foliose,” and those with shrubby upright or dangling strands are termed “fruticose.”

Because lichens absorb so much of their nourishment from the air and rainfall, they serve as living air quality indicators. By monitoring a region’s changing balance of pollution sensitive species and pollution tolerant species, a researcher can visually chart the build-up or decrease of pollutants such as sulfur dioxide and nitrogen dioxide.

Doubly Dead: Taxidermy Challenges in Museum Dioramas

A visit to the wildlife dioramas at Carnegie Museum of Natural History is an opportunity to repeatedly admire the illusions created by teams of skilled taxidermists. None of the featured creatures are alive, but many of them appear to have just paused. Some, such as the pronghorn antelope, pictured above, even seem to be frozen in motion.

In several three-dimensional scenes, where the animal subjects are predators or scavengers, the taxidermists involved in creating the exhibit faced another challenge – presenting the preserved remains of a dead animal as a dead animal. The task, as the somewhat gory details in the pictures below attest, is undoubtedly more difficult than it sounds.

A dead salmon is front and center in the Alaskan Brown Bear diorama, and the pink flesh the cubs are consuming doesn’t look much different than what’s available at supermarket fish counters.

In the Hall of African Wildlife there’s no blood visible on the Lesser Egyptian Jerboa under fennec’s paw. The curled position of the prey’s feet and back legs indicate the struggle with the big-eared fox is over.

In creating life-like mounts, taxidermists use glass eyes of the proper shape, size, and color. The glass eyes appear to have lost their luster for the seal that serves as a prey detail in a Polar Bear diorama.

In one of the oldest dioramas within the Hall of North American Wildlife, the centerpiece presence of a dead bull elk indicates the role of both California Condors and Turkey Vultures as scavengers.

Taxidermy details that indicate the elk’s browsing days are over include dull eyes and a lolling tongue. The tricks of taxidermists are important when they help to explain the role of predators and scavengers, the bedrock biological principle of life from death.
