In a earlier article I famous {that a} Wikipedia entry on Charles Otis Whitman of the College of Chicago said that he despatched the final Passenger Pigeon named ‘Martha’ to Cincinnati Zoo in 1902. Martha died on 1 September 1914 and the species turned extinct. The declare that Martha got here from Whitman is just not supported by some modern accounts however might be deduced from one other. That is complicated as a result of each accounts arose from the identical supply.
The 1948 Model
There isn’t any doubt that each Whitman and Cincinnati Zoo bred Passenger Pigeons. Each had been unsuccessful in sustaining a breeding inventory. An account of Martha’s origins and demise, written by William C. Herman, was printed in The Auk. Herman wrote:
The person who, higher than anybody else, is certified to contribute the image of the ultimate act of this nice tragedy is Mr. Sol A. Stephan of the Cincinnati Zoological Gardens in Cincinnati, Ohio (now nonetheless dwelling on the age of 97) and from him the current author obtained a lot of the data right here offered.
Mr. Stephan took cost of the Cincinnati Zoological Gardens in 1878, earlier to which period the Zoo had Wild [Passenger] Pigeons on exhibition and had had some success in elevating them in captivity. At the moment there have been 4 pairs within the aviary which had been bought in a western locality at a value of $2.50 per pair; and others had been added to this quantity. At this early date, Wild [Passenger] Pigeons had been nonetheless to be present in massive numbers, and a few had visited the beech timber on the grounds that later had been taken over by the Cincinnati Zoo. Even presently Mr. Stephan realized that the Wild Pigeon was changing into scarce. Way back to 1857 a invoice to guard it had been proposed by a committee of the Ohio Senate, however no motion was taken. As costs turned greater, Mr. Stephan turned very anxious for the preservation of the species, and he decided to breed the birds in captivity to be able to have them for functions of exhibition. Their habits had been rigorously noticed, with particular consideration to the food plan. He realized that they thrived finest on a combined meals of cracked corn, wheat, crackermeal, cooked liver, and eggs. Whereas current discoveries have been made within the feeding of birds and mammals in captivity, the food plan utilized by Mr. Stephan appeared to be ample.
Herman then went on to explain the breeding quarters and the nesting. Every nest contained one egg and the birds bred solely every year. Stephan was reported right here as having bred 14. The birds turned very tame and lived for 10-15 years. Finally he was left with two birds, one male, one feminine. Herman continued:
When different zoological gardens realized that the Cincinnati Zoo had the one remaining pair, they provided costs which rose from $100 to $1000 for the pair. Right now Mr. Stephan was not anxious to get rid of such a precious asset and properly saved them, for they attracted ornithologists and different scientists from distant elements. The feminine of this final pair had been hatched within the Cincinnati Zoo in 1885, and was named ‘Martha,’ in reminiscence of the spouse of a pal of Mr. Stephan. This feminine pigeon turned the final survivor of the billions that in flights as soon as darkened the sky.
Martha and her mate constructed however one nest, and the lone egg that she laid on this proved to be infertile. Since each birds of this final pair had been so outdated that it was apparently inconceivable for them to rear any younger, eggs from Martha had been positioned beneath incubating Rock Doves (home pigeons), within the hope that the latter would possibly hatch and rear the younger to maturity. This failed as a result of the eggs had been infertile.
The male of the pair died having been in captivity for 26 years. Martha lived on and died aged 29 (‘an unusually outdated age in captivity’). She was discovered useless. Her pores and skin was despatched to the USA Nationwide Museum in Washington, D.C. Mr. William Palmer, the taxidermist, eliminated the pores and skin. Dr. Robert W. Shufeldt made an anatomical dissection and printed an outline of this (Auk, 32: 29-41, pls. 4-6, 1915), giving the reason for loss of life as superior age’.
The 1908 Model
An account of Whitman’s work with Passenger Pigeons was printed in The Auk in 1908 in an article written by Ruthven Deane (1851-1934), a number one beginner ornithologist of his day. Whitman had obtained his birds, as a part of his huge research of the evolution of pigeons, from a David W. Whitaker of Milwaukee. A flock of 15 had been bred from a single pair ‘of younger birds which he acquired from a younger Indian who trapped them in Shawano County in northeastern Wisconsin’ in 1888. From 1896 to 1897 Whitman purchased, in dribs and drabs, the entire flock. Throughout 1897, 9 younger had been hatched however solely 4 lived. in 1998, he gave 7 birds again to Whitaker. Once more eggs had been layed by his birds however solely 2 hatched. Steadily the flock turned depleted as even fewer of the eggs hatched whereas adults had been misplaced or died. By the tip of 1907 all of Whitman’s Passenger Pigeons had been useless. He was left with two male Passenger Pigeon x Ring Dove hybrids which he discovered to be infertile.
Whitaker had 4 reside males in 1908 which died presumably over the subsequent few years.
What is obvious from Deane’s paper is that Whitman despatched a feminine hen to Cincinnati Zoo in 1902. However then issues get complicated. Deane reported:
For years we’ve identified of the Passenger Pigeons within the Gardens of the Cincinnati Zoölogical Co., and I’m a lot indebted to Mr. S.A. Stephan, Normal Supervisor, for the next report of their flock, in a letter written November 9, 1907.
The unique flock, which got here from Michigan in 1875, consisted of twenty-six birds, about half males and half females. A short while later, nevertheless, 5 or 6 of those escaped. They’ve bred on occasion and we’ve raised about twenty-three birds. In no occasion has multiple egg been deposited at a time. At the moment our flock has been decreased to a few, one male from the unique flock, now about twenty-three years outdated, one male, which we raised, is about eighteen years outdated, and one feminine that we obtained from Prof. Whitman’s flock in 1902, which is about twelve years outdated. We now have by no means detected any explicit illness which has precipitated the lower of the flock, however have attributed it usually to outdated age.
Deane concluded:
The remnants of the Milwaukee and Cincinnati flocks now quantity however seven birds (6♂︎, 1 ♀︎) with little or no likelihood of additional copy.
That is the model of the story that appeared win the world’s press after the loss of life of the hen in 1914. Additional media consideration adopted the publication of the paper describing the dissection of the hen on the Smithsonian by Robert Wilson Shufeldt (1850-1934) who was medically certified. In it he wrote:
On February twenty-first, 1914, Mr. S. A. Stephan, Normal Supervisor of The Cincinnati Zoological Firm, of Cincinnati, Ohio, wrote me that ” Our Passenger Pigeon has been promised to the Smithsonian Establishment when it dies. This hen is a feminine and now about 29 years outdated, and the final certainly one of a flock of eight that we acquired in 1878.” I’ve since realized that it was hatched within the Backyard.
Shufeldt, himself a vibrant character with a sure notoriety, famous two issues that appear odd. First he wrote:
From Mr. Stephan, who wrote me on the seventh of September, 1914, I study that “our feminine passenger pigeon died September 1st [1914] at 1 P. M. of outdated age, being about 29 years outdated.” It was virtually instantly packed in ice and shipped to the Nationwide Museum at Washington, D. C., the place it was acquired in superb situation on the fourth of that month.
However exterior appearances had been misleading. He was with William Palmer of the museum who skinned the birds for taxidermy. Then, after a ‘late lunch’, Shufeldt started his dissection however had a shock:
I discovered, on the best facet of the stomach, a slit-like opening, one-half a centimeter in size, which led freely into the belly cavity, and from which blood was oozing. This opening I enlarged to be able to withdraw the viscera for the aim of creating {a photograph} of them, earlier to continuing with the dissection of the organs inside. This has been my observe for an incredible many sears.
A lot to my shock, I discovered a amount of blood (not clotted) within the belly cavity, and the best lobe of the liver and the gut virtually solely damaged up, as if it had been carried out with some instrument. As to the gut, it was lacking altogether, whereas the best lobe of the liver was in scattered fragments The firmer organs had been apparently intact, however didn’t occupy their regular positions.
Later within the paper he continued:
There was no proof no matter of the presence of the gut in any a part of its continuity save a chunk about 8 mm. in size, the place it emerged from the gizzard and the ragged margin surrounding the belly boundary of the vent. All of the portion referred to was not within the belly cavity. Your complete proper lobe of the reasonably massive liver was in a disintegrated situation, exhibiting its inside construction, and exposing the organs normally hid by it to view. The center was in its regular place, whereas the gizzard was rotated to the left facet. I found no blood clots or parasites of any form within the belly cavity
The inference from this description and the very detailed of how the hen was acquired and dealt with on the Smithsonian is obvious: someone had carried out one thing to the specimen in Cincinnati. Had someone poked and pulled contained in the belly cavity with an extended pair of forceps, the one approach I can consider by which the entire gut and chunks of liver may very well be eliminated by way of a half-centimetre slit? However who, and why?
Additionally of curiosity with respect to the alleged age of the birds is:
The ft had been of a deep, flesh-colored pink, clear and wholesome, whereas the claws offered no evidences indicative of surprising age, although not a number of of wear and tear.
Two totally different accounts
The reader of those accounts is subsequently in some doubt as to which model, if both, is appropriate. Each accounts are from the identical supply, Sol Stephan. In 1908 he wrote that the final surviving feminine was one despatched by Whitman in 1902. The wording in Deane’s article might be taken to suggest that this was one of many birds obtained from Whitaker in 1896-7. In contrast, in Shufeldt’s and Herman’s accounts written with info equipped by Stephan after the loss of life of the final hen in 1914, Stephan said that the feminine had been hatched within the Cincinnati Zoo in 1885, was named Martha in reminiscence of the spouse of a pal, and had died aged 29.
There’s a nice distinction within the age of the final Passenger Pigeon at loss of life, 29, if it the one bred at Cincinnati. If we calculate from Stephan’s account from 1907, then, had the hen come from Whitman, it might have been roughly 19 at its loss of life, a lot nearer to the 10-15 years lifespan quoted for different birds saved in captivity.
Completely different accounts pre-date the hen’s loss of life. For instance, in William T. Hornaday’s Our Vanishing Wild Life (1913), the hen is described as ‘twenty years outdated in 1912’.
A key query is in fact, was doable to know the identities and historical past of the person birds at Cincinnati Zoo? Have been they ringed (banded in the united statesA.)? Shufeldt made no point out of 1 being discovered at post-mortem. I’ve checked out two images of Whitman’s birds that may be seen on-line and may see no hint of a hoop.
All publicity is nice publicity: A doable rationalization
Salvator A ‘Sol’ Stephan was, in his youthful days, a showman, working for a travelling menagerie and in addition as a consultant for Carl Hagenbeck, the well-known animal vendor of Hamburg. He arrived on the quickly to be opened Cincinnati Zoo in 1875 with an elephant. Persuaded to remain on to settle within the animal, he retired 62 years later as Superintendent and Normal Supervisor. He died in 1949 aged 100.
Cincinnati Zoo had a troublesome time in its early many years. It entered receivership in 1898 and to be able to stop liquidation the shareholders gave up their investments of almost 1 / 4 of 1,000,000 {dollars}. Then it ran as a enterprise for 2 years. The Cincinnati Traction Firm, hoping apparently to make use of it as a advertising software for its streetcars, operated the zoo till 1917 (in some accounts 1915).
I’m wondering if the chance was taken, with the loss of life of the final Passenger Pigeon, to be sure that the attendant publicity (for which Sol Stephan was identified) confirmed the Zoo in the absolute best mild. What higher than a report longevity and the native breeding and care of a hen named Martha?
On the title there’s even confusion within the literature. Stephan wrote that she was named after the spouse of a pal. Different secondary sources say the title is after Martha Washington, with the male of the ultimate remaining pair as George.
I can not consider some other rationalization, aside from a marked lack of reminiscence, for the distinction in accounts given by Stephan in 1907 and 1914. In different phrases, my tackle the origins of ‘Martha’ is that she was, probably, the hen despatched to Cincinnati by Whitman in 1902. Shufeldt additionally remarked that the data he was given by Stephan didn’t tally with what he was informed later:
This hen is a feminine and now about 29 years outdated, and the final certainly one of a flock of eight that we acquired in 1878. I’ve since realized that it was hatched within the Backyard.
As outlined above, I’ve the sensation from studying between the traces that Shufeldt was suspicious over what he was informed concerning the age of the hen and the circumstances of its loss of life and preservation.
Errol Fuller handled the story of Martha’s loss of life in his 2014 ebook on the Passenger Pigeon:
The reality is that we do not truly know when Martha died, at the very least not with any diploma of exactitude. This lack of definitive info is basically attributable to differing accounts given by the primary keeper on the zoo, Salvator “Sol” Stephans, and his son Joseph. Each saved altering their story. Considered one of their accounts states that Martha died in her cage at exactly one o’clock on the afternoon of Tuesday, September 1, 1914. One other suggests her loss of life would possibly even have occurred some 4 hours later. One model of the story relays the romantic concept that she died surrounded by a bunch of grieving keepers. One other maintains that simply Sol and Joseph had been together with her. Yet one more is much less poetic and signifies she died alone and was discovered mendacity on the ground of her cage by an assistant keeper named William Bruntz. The reality hardly issues, in fact. Useless is useless.
Moreover, any severe try and undergo written zoo data to unravel the thriller is inconceivable; they had been destroyed by fireplace in 1963. What we do know is that the primary day of September was a swelteringly scorching day with excessive humidity ranges; maybe it was all simply an excessive amount of for a frail outdated hen. So what else is there? The reply is, not quite a bit. It appears sure that Martha was born in captivity, however the place? Mr. Stephans’ recollections had been as different on this topic as they had been on others. Maybe this was attributable to captivity, however the place? Mr. Stephans’ recollections had been as different on this topic as they had been on others. Maybe this was attributable to poor word holding; maybe it was forgetfulness or only a lack of understanding regarding previous occasions that on the time of their prevalence would have appeared unimportant.
What would occur now?
The accounts by ornithologists and aviculturists describe the failure of the faltering and early makes an attempt at what would at this time be described as a captive breeding programme for a extremely endangered species. A helpful dialogue may be had on whether or not, with the huge enhance in data of untamed animal husbandry, we may have carried out any higher in 2022. What stands out in studying the accounts is: the failure of eggs to hatch (nonetheless a serious downside), which may very well be associated to infertility, or to poor situations for incubation; the decline in fecundity because the females aged; the diploma of inbreeding. All Whitaker’s and subsequently Whitman’s birds had been descended from a single pair of younger birds which had been hand reared. My wager is that they had been from the identical nest. Due to this fact, inbreeding melancholy may account for a few of Whitman’s findings (a phenomenon he described as ‘weak spot of the germ’) and that rationalization appeared in print in 1913. The group initially saved in Cincinnati was bigger and subsequently extra genetically numerous. Nonetheless that inhabitants additionally declined over time. Vitamin may have been insufficient in captive birds. Wallace Craig recorded the behaviour of Whitman’s birds. He wrote:
A phrase as to the care of Passenger Pigeons, in case we could also be so lucky as to search out some nonetheless dwelling. Professor Whitman saved his in the identical pen with different species, equipped with the pigeonstaples of combined seed, grit, oyster shells, salt, and loads of inexperienced meals comparable to lettuce. After he had had his flock a few years, he found that they’d greedily devour earthworms, and when abundantly equipped with this delicacy the birds improved a lot in well being and vigor that Professor Whitman thought if solely he had identified of this food plan early sufficient he may need saved his inventory from dying away.
—§§§§§—
As unsatisfactory because the totally different accounts of the loss of life of what’s nonetheless presumed to be the final Passenger Pigeon (Ectopistes migratorius) are, they’re immaterial to the extinction of the species that occurred over a comparatively brief interval. I began this collection of two articles with the achievements of Oscar Riddle in discovering, firstly, the hormone prolactin and, secondly, the latter’s impact on the pigeon crop sac. Due to Riddle’s shut hyperlinks to Charles Otis Whitman, I turned fascinated by the historical past of the extinction of the Passenger Pigeon and of those that saved and bred the hen in captivity. I nonetheless have way more to learn.
Martha’s feathers weren’t in superb situation when she died and her pores and skin was not displayed by the Nationwide Museum in Washington for a few years. Nonetheless, it’s now on show, as described right here. Photographed in 2015 by Ph0705. |
