Invasion of the Species

Last summer I piled my family in the car and we took off on the trail of George Washington in Western Pennsylvania. We had colored and mounted a drawing of George Washington on a stick so we could bring him along for photo ops and
historical commentary to amuse and educate our then-8 year old.  That might have been a mistake, because  George-on-a-Stick had a surprising amount to say about beer distributors and the Pennsylvania Liquor Control Board. Imagine lots of disgruntled muttering about the 1791 Whiskey Rebellion coupled with frequent recommendations that we stop to water our "electronic horse" and sample the various beer selections.

Be that as it may, this quest is not as daft as it might first appear.  Later this year the Western Pennsylvania region will commemorate the 250th anniversary of the launch of Washington's military and diplomatic career, which occurred right here in our fair state. By 1753, the French had erected three military establishments to reinforce their claims to the North American colonial frontier at Presque Isle (Erie, PA), Fort LeBoeuf (Waterford, PA), and Fort Machault (Franklin, PA). The English weren't at all happy about this and their goal was to limit French expansion into the Ohio Country, which had already been claimed by the Virginia Colony. Acting on orders from Virginia Lieutenant Governor Robert Dinwiddie, a 21 year old George Washington was sent north with eight men on a diplomatic mission to advise the French to evacuate the region.  George's Incredible Adventure started in Williamsburg Virginia and ended at Fort LeBoeuf, in what is now Erie County Pennsylvania. The route we followed with George-on-a-Stick aligned mainly with modern highways such as Interstate 79 and U.S. Route 19, but there were some suggested rural scenic routes along the signposted Washington's Trail that are thought to more closely parallel the route Washington took in fall 1753.  You can view a map of the Washington Trail at this LINK.

George's mission failed, by the way. And that failure led directly to the escalation of hostilities in this region, what we know today as the French and Indian War or the Seven Year's War.  Following the British victory, and after a concerted military effort by an alliance of Great Lakes region Native tribes unhappy with British postwar policies was defeated, the Western PA region was considered safe for European settlement.


Washington meeting with Guyasuta, a Seneca chief who may have served as a scout for Washington when he came through the area in 1753. Guyasuta did what he had to do to best serve his peoples' interests: helping to defeat the 1735 Braddock Expedition, siding with the French in the Seven Years War, and co-leading Pontiac's Rebellion. This sculpture on Point of View Park on Mount Washington in Pittsburgh shows Guyasuta and Washington peacefully meeting to divvy up the area for settlement.

Once our 8 year old lost interest and took a nap, we silenced George-on-a-Stick's rants about the privatization of liquor sales in Pennsylvania by consigning him to the glove box. As we drove along and admired the scenery, I was struck with the realization that today's western Pennsylvania  landscape and topography would be largely unrecognizable to George.

Not just because of stuff like this, mind you, although certainly modern technology has forever altered our landscape:


The technological encroachments on our environment didn't set me wondering as I wandered, but the natural ones did. What grows and lives in the wild has changed tremendously in 250 years. George would hardly recognize this place. Sure, from a distance the hills and valleys of Pennsylvania impress, then as now.  But there are no longer flocks of passenger pigeons and Bachman's sparrows, waterways filled with long-jaw ciscos, blue walleyes, pink mucket pearly mussels and tiger salamanders. Nor do eastern elk, grey wolves, wolverines, badgers, or mountain lions populate the forests of Western Pennsylvania.  And the chestnut and elm tree forests that George saw back in his day have been decimated by fungal blights.

The flora and fauna that Washington knew as he slogged through the area have given way to myriad invasive plant species such as garlic mustard, crown vetch, yellow flag iris, kudzu, Japanese honeysuckle, multiflora rose and mugwort. Critters like everyone's favorite Halyomorpha halys (aka the lowly Stink Bug), wooly adelgids, Zebra mussels, emerald ash borers, Asian multicolored lady beetles, red foxes, house sparrows, European starlings and honeybees are not creatures George Washington would have recognized as native to the Pennsylvania forest.


Exotic species aren't intrinsically "bad" but they get defined as invasive when they out-compete and in some cases eradicate native species vis-a-vis disrupting the ecosystems that they invade.  Invasive plants were initially transplanted -- either intentionally or accidentally -- from faraway places. Once established, invasive species are difficult to eradicate because they aren't controlled by natural forces. Native wildlife doesn't find them tasty, and they aren't susceptible to controlling diseases. The species gradually became more abundant than native plants in synch with the original ecosystem due to natural predators.

Several days a week, my colly collie and I walk two to three miles of trails at North Park.



It's been a pleasure to watch the woods come alive all around us these last few months.  Compare the photo above with a portion of the same trail just a few short weeks ago:



So I'll grant you, nothing in nature ever stays the same. Still, I've been gobsmacked recently by how the prolific invasive species choke out native plants in the forest understory. I'm not sure what to do about that because I have to admit that I like yellow flag irises, multicolored ladybugs, honeybees, multiflora roses and Japanese honeysuckle. They are so familiar and ubiquitous that I didn't even realize until this week that they are considered invasive. Long may they flourish (within reason), I guess.

While we're at this environmental manipulation stuff, let's bring back mountain lions and wolves. As apex predators they can control Pennsylvani's whitetail deer overpopulation.

But there's a line to be drawn in terms of dealing with invasive species. Stink bugs, for instance. They don't particularly bother me but since they serve no apparent useful function I'll not argue for them to stick around. If we can safely dispose of them, I'm for it.

I'm citing scientific precedent as upholding my right to manipulate the environment. Reactive phosphorus was one of the building blocks for the creation of early life forms but it's not native to Earth; the phosphorus apparently arrived some 3.5 billion years ago vis-a-vis meteorite bombardment. So according to scientists, the existence of life on Earth is partly due to an invasion of otherworldly meteorites.

Since my existence here is due to an invasion from outer space, I figure that makes me an invasive species. And as such I should be able to arbitrarily decide what other invasive species get to stick around.  Right?

Okay, no. I'm kidding. Really, we're not an invasive species. Though like the worst invasive species, we humans have indeed done harm to our environment. But we are native apex predators, albeit the most dangerous species around. I'll grant that labeling other species as “invasive” may be a bit of an arbitrary conceit, since nothing in nature ever stays the same. But that doesn't mean it is appropriate or responsible to take a laissez faire attitude toward environmental change. 

In Antoine de Saint-Exupéry's The Little Prince, the protagonist spent his days in the thankless task of pulling out the baobab trees that threatened to split his world into pieces with their roots.  It's an equally impossible task to purge the woods of invasive species and yet we'd do well to heed the words shared with The Little Prince by a fox:  "You become responsible, forever, for what you have tamed."  We haven't "tamed" our world by introducing invasive species, to be sure, but we are nonetheless collectively responsible for the resulting ecological fall-out.  I believe that we are called upon to be good stewards and so choosing which species to protect and preserve must be a process of careful collective discernment.  Highlighting all the things we can do to function as good stewards is beyond my ability, but I'm tickled by the creative ways people have found to make peace with the changes man hath wrought through careless environmental care. Including the philsophy of "if you can't beat 'em, eat 'em."  Anyone fancy a dinner of Zebra mussels with a side of garlic mustard greens, garnished with some kudzu? Right.

All of this has been much on my mind as I pack up my family and prepare to invade foreign soil as we travel abroad in search of new blog fodder this summer. We're massively excited and looking forward to new growth. Travel expands literal and psychological horizons. We intend to be gentle on the world as we unfold ourselves and explore. We will be forever altered by our travels, and while we can't promise that we won't leave bits of ourselves behind in the process, we promise it will only be the best bits.

And in case you're wondering, George-on-a-Stick is staying at home.  We grown-ups don't want to share our beer.

Pittsburgh's Fountain of Youth (Too bad, Ponce de León).


We all know that the Spanish explorer Juan Ponce de León discovered Florida whilst looking for the Fountain of Youth...which Captain Jack Sparrow came across in the fourth installment of the Pirates of the Caribbean film series. 

Okay, not exactly. 

We mere mortals have long been fascinated by tales of miraculous waters that promote longevity. Alexander the Great was said to have been searching (when he wasn't conquering the known world) for a river whose curative waters reversed the damage of aging. In some Islamic traditions the revered character al-Khidr, a contemporary of Moses, is said to have drunk from the waters of life and become immortal. The medieval tales of Prester John, a Christian king of legendary lands either in Asia or Africa (depending on the legend) included a Fountain of Youth. 

Stories about restorative waters peaked in sixteenth century Europe when they became associated with the wonders of the New World. Juan Ponce de León led the first European expedition to Florida in 1513 but his meticulous exploration notes say nothing of a fountain quest. The connection between this Spanish explorer and the Fountain of Youth was established in a 1535 chronicle called Historia General Y Natural de las Indias by Gonzalo Fernandez Oviedo. The chronicle claims that de León was searching for the waters of Bimini to cure his impotence when he accidentally discovered Florida. Yes, impotence. Now we know what Ponce de León was really looking for. There are several Florida tourist attractions purporting to be de León's fountain, but no word as to whether any of them cure impotence. 

Truth is, if de León really was searching for the Fountain of Youth, he needed a better map. Because it's here in Western Pennsylvania.


 And how do I know this is the Fountain of Youth? Because it says so, silly:



I came across our Fountain of Youth a few months ago when I was driving around North Park looking for the old buffalo paddock site. As I drove down Kummer Road I caught a glimpse through the trees of this springhouse built into the hillside, and with screeching brakes stopped to check it out. I've revisited the grotto many times since.  



It's not surprising that the springhouse blends in so seamlessly with its surroundings. The first County Parks Director, Paul B. Riis, was an advocate of naturalistic construction for municipal recreation facilities that would, as described by the Pittsburgh Press,  "...represent natural bodies of water with overhanging cliffs, whatnots and doodads that put in the 'artistic touch.' "  According to the timeline of the Latodami Nature Center in North Park, Pittsburgh's Fountain of Youth was built in 1938 as "....a springhouse designed as a grotto typical in every detail of a Roman cavern."  It was likely built by Works Progress Administration (WPA) laborers, who constructed so many other park buildings, paths, shelters, and landscaping.

Unfortunately the spring waters of our Fountain of Youth didn't flow free and clear for long. In January 1953, the Pittsburgh Press reported that the pump "...recently developed the squeaks and the dry wheeze, and then broke down completely" and gleefully opined that "....old age had set in."  The handle was replaced due to popular demand and the waters were tested: "Chemists said it was cold, pure and clear but couldn't find anything in it to clear up wrinkles or falling hair." 

Alas, a few years later the pump handle was removed entirely. On May 11 1955 the State Health Department declared the spring waters unfit for human consumption due to "coliform organisms."  A Pittsburgh Press article lamented the news for fans of the spring:  "As a matter of fact, over the weekend we have folks coming all the way from Butler to collect supplies and take them home."  Hopefully those Butler folks boiled their water before using it!  

A subsequent article in the Pittsburgh Press from October 1956 confirmed that the Fountain of Youth would remain closed due to impurities in the water supply.  R. Jay Gangwere's 1986 history of North Park in Carnegie Magazine explained that "When the golf course nearby fixed the leaks in its irrigation system, the Fountain of Youth dried up, but the grotto remains."   It would be ironic indeed if repairs to a broken irrigation system were to blame for killing Pittsburgh's Fountain of Youth. The water supply in North Park had been problematic from the beginning, delaying construction of the golf course and swimming pool until an artesian well was dug in 1930.  A 1932 article in the Pittsburgh Post-Gazette noted more water woes:
The quality of water used there [in the golf course area] has been a matter of great concern for some time. Its high basic carbonate and sodium chloride content is of a toxic quality, producing alkalinity on the greens....This problem, the director said, he hoped to solve either by application of harmless chemicals or by connections to another well two miles down the valley from the golf course.
County Park Commissioner Riis even blamed the death of several North Park buffalo on water that they drank from a near-by creek.

We must assume that the water is still unfit for human consumption fifty years later (because, really, do you want to be the test case that disproves this?). However, there remains a running spring on the Fountain of Youth premises to be explored, if you're hardy enough to climb down through the brush and poison ivy.  A worker in the North Park office told me that the concrete around the grotto had been repaired in 2004-05, and a Girl Scout had remounted the medallion in 2009. The Fountain of Youth reportedly also hosts a nearby geocache. 

I'd tell you exactly where to find the North Park Fountain of Youth, but that would defeat the purpose of a quest, wouldn't it? If you do visit, remember this: the waters aren't purified. 

Oh, and remember, too, that Ponce de León allegedly searched for magical waters to reverse his impotence. We don't know if he ever found his Fountain of Youth, but we do know that he had 21 children. 

Be careful what you wish for, folks, and don't drink the water.

Oh Give Me a Home: the case of the unlikely Pittsburgh buffalo

I recently read Bienville's Dilemma by geographer and researcher Richard Campanella, a wonderful collection of essays about the sublime and complicated city of New Orleans. I am normally a very fast reader but I took my time with this book. I savored each essay and my neurotransmitters frissoned as Campanella established connections that I had been straining toward in my readings about colonial and antebellum NOLA. Truly a wonderful book, and it even provided a delightful tidbit of information that set me off on a tangent: buffalo once roamed the wilds of Louisiana.

Maybe you knew that, but I surely didn't. I am captivated by this new knowledge, and not merely because it evokes tawdry images of bison wandering the Vieux Carré wearing "Who Dat?" caps, carrying go-cups, and baring their breasts for beads. (Although now that I've created that image, I'm having a hard time letting go of it...)

Certainly I knew that buffalo roamed the vast expanse of the Louisiana Purchase, but not that they hung out on the deltaic plains of Louisiana itself. Campanella details their presence in his essay "Forest Primeval Reconsidered."  The first documented sighting of Louisiana bison occurred in 1699 when Canadian explorer Pierre Le Moyne, sieur d'Iberville et d'Ardillières, was charged with finding the mouth of the Mississippi River in order to further French interior trade interests. He described seeing "...three buffaloes lying down on the bank" which quickly disappeared into the bamboo brush near what Campanella posits was present-day Jackson Square. Iberville later saw a herd of some 200 bison upriver.

These animals, like many present-day New Orleanians, came from Somewhere Else. How did they get there? Based on eyewitness explorer accounts, it seems that bison had expanded their migratory range to the Gulf and Atlantic Coasts due to several natural and man-made factors. A long-term drought forced thirsty buffalo from the western plains into the Ohio River Valley, and from there many wandered south. The buffalo were also able to establish themselves further afield due to the massive Native population decimation due to lack of resistance to European-imported diseases; that in turn meant fewer hunters and diminished land cultivation, allowing prime grazing grasses to spread and buffalo to roam.

So it came to pass that there were buffalo in Louisiana. And Iberville, lucky guy, was charged with domesticating those Louisiana buffalo and raising them for their wool.

Yes, really. The French were master traders, and hit upon the notion of cultivating herds of sweet, docile buffalo to free themselves from dependence upon Spanish and English wool imports. But let's face it, herding massive uncooperative wild beasts in the days before electric fences and tranquilizer guns was not an easy task. I'm guessing it's not an easy task even today. Even presuming one could successfully herd bison, the logistics of restraining a buffalo for live shearing are mind-boggling.

Iberville bribed some Native peoples with promises of weaponry, and he got a few head of bison that way. However, French plans for buffalo domestication and wool-gathering were doomed by the temperament and size of the beasts.

From Antoine Simon Le Page Du Pratz, Histoire de la Louisiane (Paris 1758) from "How to Prepare Buffalo, and Other Things the French Taught Indians about Nature" by Christopher Morris in French Colonial Louisiana and the Atlantic World.  Probably a calf but perhaps this illustration is a fantasy depiction of a sheared buffalo?

After not hitting it big with the buffalo wool trade, the ever resourceful colonial-era French established a brisk trade in buffalo hides and meat. Un boeuf savage was still plentiful in Louisiana some thirty years later after Iberville's failed buffalo ranch, as described by Jesuit Father du Poisson's observations of bison roaming in the Baton Rouge area "....in herds over the prairies, or along the rivers...."

But so prevalent was bison hunting and trade that by the time the French sold their regained Louisiana lands to Les Américains in 1803, free range bison had been eradicated from the lower Mississippi.

And we all know how the story of bison on the rest of the North American continent ends. A species that once roamed these lands in the tens of millions was reduced to an estimated 23 known survivors in the wild by 1902.

From Francisco Lopez de Gomara, Historia General de las Indias (1553) in "How to Prepare Buffalo, and Other Things the French Taught Indians about Nature" by Christopher Morris in French Colonial Louisiana and the Atlantic World.

Prior to reading all this, the extent of my knowledge was that white people nearly hunted bison to extinction in the 19th century, and that the birth of a white buffalo calf is considered a prophetic blessing for many Native American and Canadian First Nation tribes.


Arguably stranger than the notion of Louisiana bison are Western Pennsylvania bison. As anyone knows who's ever tried to purchase a level backyard lot in these parts, PA ain't no plains state. Still, we've got bison up in here. In fact, according to the Penn State College of Agricultural Sciences, bison once roamed the mountain slopes and valleys of Pennsylvania at least until 1801, which is when this state's last native free range bison was shot.

I have a vague childhood memory of peering from a distance at a few scraggly buffalo at Allegheny County's South Park in the early 1970s. My breath clouding the closed car windows and my as-yet undiagnosed near-sightedness left me vastly unimpressed by this experience. I couldn't tell if the lumps in the distance were buffalo or dirty rocks, but my father assured me they were buffalo.

He was right. At one time, there were herds in Allegheny County kept on public display at both North and South County Parks.

Thirty-six bison were imported to Pittsburgh in 1927 to bolster visitation to those newly created public parks, with the expectation that Native Americans could be recruited to care for the beasts. The animals were trucked in from a Schnecksville PA preserve founded in 1906 as part of a big game conservation effort, a site known today as the Trexler Nature Preserve and home of the Lehigh Valley Zoo. The starter herd consisted of 4 large bulls, 3 medium-sized bulls, 3 young males, 3 mature cows, 3 medium-sized cows, and 2 yearlings. Allegheny County paid $150 a head, with a half dozen beasts thrown in for free.

A 1927 Pittsburgh Press article described the cross-state buffalo odyssey:
The advertising angle of the caravan as it passes across the state with its burden of buffaloes is not being overlooked and large signs will tell any who stop to inspect the unusual caravan that they are intended for the new county parks in Allegheny county.

Three families from the Blackfeet reservation in Browning, Montana were hired to care for the herd from 3 May 1928 to 25 March 1931.

From a 1986 article in Carnegie Magazine:
In those early experimental days it seemed obvious that parks should have wild animals, and that the ideal caretakers or curators of wildlife would be real Indians. And so the county commissioners brought two tribes of Indians from a Montana reservation to live in the parks. Chief Big Beaver and his tribe went to North Park, and Chief Wild Eagle and his tribe went to South Park to tend the animals delivered there in 1927.
This was no small affair. Thirty-six head of buffalo were trucked in by means of a motor caravan, led by a tank. Reporters followed in private cars. Deer and other native wildlife from Pennsylvania were also provided as part of the Indians' herd. But the gesture ended badly. The Plains Indians found the winters here too severe, and left after one season. In North Park, the Indian "curators" of the herd did not so much protect it as use it the way their ancestors would have--for food and clothing. They were asked to leave. The romance of the American Indian could not survive in a county park.

Allegations of poaching and alcohol abuse against the natives were made. However, according to a 1931 Parks report cited in Oliver's Post-Gazette article, the Blackfeet themselves asked to return to their reservation, giving no specific reason other than a mention that Mrs. Big Beaver "....was ailing and enduring considerable physical suffering."  A Pittsburgh Post-Gazette article from April 1929 makes it clear, however, that there was little compassion involved when it came to dealing with the imported Native caretakers: 
....Big Beaver may be requested to resign this fall to take the frequently recurring Indian problem off the minds of the commissioners.

Commissioner E. V Babcock threw the problem off his shoulders with one terse expression.

"Let's get them the deuce out of here."

"We keep these Indians all winter while they loaf," Commissioner Charles C. McGovern declared. "Now when we want them in the summer they want to leave."
Not surprisingly, an obituary for "Chief Big Beaver" doesn't mention anything about boozing or alleged bison poaching:
Aug 7, 1958
Eddie Big Beaver Services Set for Saturday Morning
Funeral services have been set for Saturday, August 9, at 10Am in Little Flower Catholic Church for Eddie James Big Beaver, Sr., 79, whose body was found in an irrigation ditch between Yakima and Toppenish, WA, early this week. Authorities believe his body had been in the ditch about six days before discovery. Big Beaver was a full-blood Blackfeet Indian who spoke excellent English and was regarded as a competent game-keeper, experienced in the handling of all kinds of animals and an experienced show man, having done this type of work in different sections of the US. In 1931, during his employment with South Park, a director for the Bureau of Parks described him as a “picturesque full-blood Blackfeet.” During his lifetime his activities were many and varied. In 1935 he and four other Blackfeet Indians were employed by Ringling Bros. Circus. He was also a one-time game warden at Pittsburg. In 1936 Big Beaver was requested to participate in the Natioinal (sic) Folk Festival at the Texas Centennial, an educational and cultural organization that brought together different Indian groups from many regions of the US In 1939 he was employed by the Twentieth Century Fox Film Corporation in the motion picture “Susannah of the Mounties.” Survivors include sons, Sam Wolverine, Eddie Big Beaver Jr. & Lynus; Daughters, Joyce Boy and Margaret Boy and 11 grandchildren. [Death was due to a fractured skull from a blow on the head.].
                     Obituary reproduced from http://prairiemary.blogspot.com

Big Beaver was a larger-than-life character, which was exactly what the newly created Allegheny County Department of Parks was looking for. Just as the colonial French had recruited Native peoples for their Louisiana bison farming plan, the County Commissioners wanted to promote their new "People's Country Clubs" and weren't above using the Blackfeet families as de facto sideshow attractions. That neither attempt at Native exploitation worked is poetic justice, I think, especially given the sustained prejudicial attitudes towards Natives.

Following the departure of the Blackfeet tribe, a 1931 Parks report opined:
 ....the money....was well spent...As was hoped, they drew to the parks and entertained thousands of delighted children and adults...It is, of course, to be expected that the red man sooner or later falls into the irresponsible ways of his people.

The County was clearly not sentimental about anything associated with its buffalo management. Blaming fecund bison, by 1933 the Pittsburgh Press was writing articles like the charmingly entitled County Finds Buffaloes Are Now White Elephants: This Unnatural Brand of Too Rapid Evolution Leads Commissioners to Believe the Only Place Poor Bison Are Wanted Is on Wooden Nickels (the article is a wee bit longer than its title). In it, the County Parks Director claimed that due to the complexities of caring and keeping of 39 buffalo when a herd of 20 would be sufficient, consultation with a game conservationist was in order. And so it came to pass that in December 1937, the next County Parks Director announced plans to shoot six of 18 bison to cull the South Park herd, donate the meat to the County Jail, and transfer one lucky live cow to North Park.

In North Park, the bison were confined to an area around Parish Hill bounded by Lakeshore Drive and Pearce Mill Road. This herd ultimately did not flourish and "conflict among the older buffalo" was cited in a 1930 Parks report, which was soon dealt with by castrating the most aggressive bulls. A year later, a Parks report stated that having "unsexed" a few bulls "....the bachelors and, hence, the herd life is much more peaceful."  No word from the "unsexed" bulls about how they felt about this development but it was likely cold comfort when a 1937 County Parks report stated that "Expert authorities....assured the Department that Allegheny County has the finest specimens of buffalo and deer east of the Rockies."

Given regular culling of herds and "unsexing" the bison no doubt appreciated the later development of reliable and non-invasive ungulate birth control.

Visibility problems hampered visitors from spotting the North Park buffalo, and in the 1940s the entire herd was trucked off to South Park. The newspapers of the day regularly reported on their  escapades. Things didn't end well for a bull named Hitler and one has to believe that names are linked to destiny.  From the Pittsburgh Press, January 21 1940:












Pittsburgh Press, 21 January 1940

Today a herd of buffalo remains at South Park (presumably not bearing the names of notorious European rulers). They were apparently on their break when we first visited, but my kids did claim to sighting 427 avian waterfowl, a dead frog, a groundhog, and a flock of turkey vultures that day. Oh, and this sign on the paddock (which was frankly a relief because I'd forgotten to bring any buffalo treats).


A second visit in July 2012 yielded an impressive view of the herd. If we counted correctly, there were 8 adults, 2 juveniles, 2 calves, and a lot of flies.



There have also been bison at the Pittsburgh Zoo as far back as the turn of the last century.  Judging by the frequency of their press coverage over the years, the Zoo bison captured the public imagination in ways that the more anonymous bison herds at the County parks did not (exceptions made for Hitler and Napoleon).  The Zoo buffalo were apparently prone to wandering.

Pittsburgh Daily Post, 17 October 1915


Life for Zoo bison wasn't all fun and games and merry chases. In 1906, two Zoo bison who had been separated from the herd due to mutual aggression apparently agreed to meet behind the parking lot to sort things out later:
In the dead of night, several days ago, the animals tore down the barriers and, with roars of rage, fought in the darkness. When they were finally separated both were bleeding from many wounds and the flesh along their flanks was ripped and town. The dead buffalo will be mounted and preserved at the Carnegie Museum. from The Pittsburgh Press, October 1906
Perhaps in revenge for that bison stuffing and mounting, in 1920 an irate mother bison attacked a 60 year old man who tried to pet her newborn calf: "He was trampled before employees of the Zoo could reach him. Keeper Ernest Tretow and several laborers dragged him from under the hoofs of the angry mother and out of the pen." When another baby was born in 1934 and twin buffalo babies in spring 1936, there were no newspaper reports of goring.

Lesson learned: leave the newborn baby bison alone.

Then there was the threat of the bison Anthrax epidemic of 1947 which killed two or three buffalo and resulted in the temporary closure of the Zoo. According to a Pittsburgh Press article from November 24 1947, officials were quick to reassure the public then quarantine and sanitize the animals: "The buffaloes...will be thoroughly scrubbed and disinfected." Public safety assured by a herd of sparkling clean buffaloes, the Zoo re-opened a month later.

My favorite documented Pittsburgh Zoo bison story concerns the consequences of a labor dispute and sit-down strike by zoo attendants in July 1951. Due to the strike the animals didn't get fed for a day, because apparently it's really hard to get scabs to cross a picket line to toss raw steak to the lions. A Pittsburgh Press report noted that the next day the buffalo scored:  
"Only a few of the animals had been fed by noon today. These were the buffalo and deer whose attendants, although officially on strike, came around to the zoo early this morning to feed their charges." 

The last public mention I can find of the Zoo herd is of a 75 pound bull calf born on 25 April 1991, bringing that herd count to seven. The bison herd had been evicted by 2003 when the Zoo closed its North American animals exhibit for expansion in keeping with its strategic plan. My inquiries of Zoo personnel as to where the bison went came up empty.

One might even say that I was buffaloed in my attempts to determine their fates.

I later learned that the Zoo's bison were humanely dispatched, having contracted a contagious disease that would not allow them to be integrated with other bison herds.

Today there are plenty of bison residing in Pennsylvania on privately owned ranches, but those herds are bred for their meat rather than maintained on exhibit for the public. The Allegheny County Parks and Pittsburgh Zoo bison were unique exhibits that tried to balance enclosure with encounter and education, albeit with mixed results.

Fun bison facts:
  • In the seventeenth century, French explorers in North America referred to the new species they encountered as "les boeufs", meaning oxen or beeves. The English, arriving later, changed the pronunciation to "la buff". The name grew distorted as "buffle", "buffler", "buffillo", and, eventually, "buffalo".
