HUTIAS: ABACO’S EXTINCT RODENTS LIVE ON… ELSEWHERE  

Note: my original article on the Hutia predates Dorian & a few references may be a bit out of date

The Bahama hutia (Geocapromys ingrahami) has the distinction of being the only indigenous land mammal in the Bahamas. Historically found on a number of islands, the species is now confined to very limited locations. Abaco is, sadly, no longer one of them; they are officially shown as extirpated here from about 1600. Hutias had been recorded on Great Abaco by early explorers from Europe, but their survival was already threatened by hunting and land clearance as the human population expanded.

Bahamian Hutia (Cole Fiechter)

Further evidence of their long-term existence on Abaco – prehistoric, even – comes from research carried out by divers in the land-based Blues Holes. SAWMILL SINK has been a particularly rich source of the remnants of early creatures, including well-preserved skeletons, carapaces or other remains of crocodiles, turtles, birds, bats – and hutias. These date from the Pleistocene epoch of the Quartenary period, spanning roughly 2.5m years and ending some 12,000 years ago. You can see some of these treasures in the wonderful Natural History Museum at Friends of the Environment in Marsh Harbour.

The population of the extant Bahama hutia species Geocapromys ingrahami became so depleted that by the 1960s they were considered to be extinct. Then in 1966 a colony was discovered on East Plana Cay. Some have since been relocated (see below) and the overall population is now confined to a handful of locations, for which reason the Bahama hutia is IUCN listed as vulnerable. All the usual man-caused threats to their survival apply, as well as predation by dogs and feral cats. One place to find them is in the Exumas, but because they are mainly nocturnal creatures and there are few of them, a sighting is a rare event, let alone getting a decent photo op.

The terrific header image and the second image were taken by teenager Cole Fiechter while on a sailing trip with his parents and brother in the excellently named ‘Truansea’. On the beach of the Exumas Land and Sea Park at Warderick Wells, they encountered “a guinea pig with a rat’s tail”: a hutia. Cole’s photograph features in the indispensible Guide to the Natural History of the Bahamas, with which I was peripherally involved. See the cover on the sidebar.

MARK CATESBY‘s take on the hutia in the c18, where he describes it as a rabbitHutia by Mark Catesby (c18)

The BAHAMAS NATIONAL TRUST notes that “Bahama hutias occur naturally only on East Plana Cay (located between Acklins and Mayaguana). Historically however, they were found on ten Bahamian islands. In a move to protect the species, a small Bahama hutia population was transplanted to two locations – Little Wax Cay and Warderick Wells (Exumas). These three locations now host the only known populations of this particular species in the whole world”

It looks as though Warderick Wells might be your best bet to see a Bahama hutia if you are visiting the Bahamas. Don’t be too confident of coming across one – but if you do see one, you will have had the pleasure of seeing a very rare creature.

ECHINODERMS, DOLLAR DOVES & PETRIFIED BISCUITS


Sand Dollar, Abaco Bahamas (Keith Salvesen / Rolling Harbour)

ECHINODERMS, DOLLAR DOVES & PETRIFIED BISCUITS

Echinoderms (Gr. ‘Hedgehog Skin’) comprise a large variety of sea creatures characterised (mostly) by radial symmetry. In a nutshell a creature with radial (as opposed to bilateral) symmetry can be divided into equal portions from the centre, like a cake. It has no left or right side and no definable front or back.  It is multidirectional from the centre, where the mouth is located. It obviously has a distinct upper side and an underside, but that has no bearing on this form of symmetry. 

Ten dollar Sand Dollar coin, Bahamas

Within the family of radially symmetrical animals, echinoderms (starfish, sand dollars and sea urchins) are unique in having five-point radial symmetry. These are the creatures you are most likely to come across in Abaco. There are two particular aspects of dollars and biscuits that merit a closer look (made more difficult by me stupidly taking photos of white things on a white background).

Sand Dollar Doves, Abaco Bahamas (Keith Salvesen / Rolling Harbour)

DOLLAR DOVES

I’m sure all Bahamians know or are aware of at least one version of the famous ‘Sand Dollar’ poem, in which the various characteristics of the test (the skeleton of the creature) are given religious significance. One verse of the poem may be puzzling: “Now break the centre open And here you will release The five white doves awaiting To spread good will and peace”.

The Sand Dollar Legend

A few years back, Senior Granddaughter was looking at some Abaco sand dollars I’d given her for her growing collection of shells. She picked one up, shook it and it rattled. She said a friend at school had told her that a rattling sand dollar has ‘doves’ inside it, and asked if we could break it open and see. I’ve learnt that it is useless to argue with her – she has the tenacity of a trial lawyer – so we did. This is what we found.

PETRIFIED BISCUITS

In common parlance ‘petrified’ is an extreme version of ‘terrified’. Literally, it means ‘turned to stone’ (L. petrus, a rock). It is descriptive of a state of fossilisation, where an animal skeleton or dead wood or plant matter turns over aeons into stone. Senior GD (a most inquisitive girl) followed up on the doves research after discovering a box containing random stones and fossils. She found these two items:

FUN FACT

Florida has an unofficial but proposed State Fossil, the ‘Sea Biscuit (Eocene Age)’. I didn’t know it before, but it turns out that more than 40 US States have State Fossils. Whatever next? State Bacteria? State Viruses?

SO HOW OLD MIGHT A PETRIFIED BISCUIT BE?

The fossil biscuits I have looked at, from Florida to Madagascar (see small image above), are said to come from three specific historic epochs – from the oldest, Jurassic (145m – 201m years ago), to Eocene (34m – 56m) and Pleistocene (0.01m – 2.6m). 

HOW DOES THAT HELP ANYBODY? BE MORE PRECISE

By all means. Here is an excellent Geochart that gives an idea of the time span. A Jurassic sea biscuit would be more than 145m years old. This chart also helpfully helps avoid confusion with the Eon Era Period Epoch ordering.

MAPPING ABACO: ON THE MAP IN 1702

MAPPING ABACO: ON THE MAP IN 1702

In the Old World, 1702 was a turbulent year politically, royally, and militarily. Treaties made were broken; new treaties were made. Queen Anne succeeded to the throne after William III died of complications after falling off his horse. Anne went on to have 17 children, any one of whom would have secured the succession, but the extraordinary and sad fact is that none survived beyond childhood. In the New World, English troops were abroad, attacking St Augustine in (then-Spanish) Florida.

Map of the Bahama Islands - Samuel Thornton - c1702

Meanwhile in the world of cartography, the development of mapping continued apace with the Dutch retaining their pre-eminence, and the French and British making important contributions. Which brings me to Samuel Thornton, hydrographer, and his mapping ways. He was the son of the more famous cartographer, John Thornton, considered the principal English chart-maker of the late c17. As his father aged, a degree of uncertainty seems to have crept in over the authorship of Thornton maps. It is clear that after John’s death in 1708, Samuel took over the business and reissued maps under his own name, sometimes with little alteration other than the name in the cartouche. However there was possibly a ‘grey area’ for a few years before, when the same practice applied. 

Map of the Bahama Islands - Samuel Thornton - c1702

Samuel Thornton’s ‘…New Chart of the Bahama Islands and the Windward Pafsage (sic)’ is thought originally to date from c1702, when presumably the enjoyably colourful Cartouche (above) in fact bore his father’s name. The map covers an extensive geographical area besides the Bahamas, with the Florida coastline revealed as remarkably unpopulated. Zeroing in on the northern Bahamas (and as is usual with historic maps), certain features stand out, not least with spelling. Andros was written Androfs (sic). The Bahama Banck (sic) is shown to extend quite a long way north of Abbaco (sic) and Grand Bahama (shown as Bahama I). And as noted in earlier posts relating to Abaco’s history (see links below), ‘Hole in the Rock’ (ie Wall) is the only mainland location marked. This was not because there was any sizeable settlement there, but because for at least a century beforehand, Abaco’s most notable topographic feature was a significant and instantly recognisable navigation marker for shipping at the southern end of the island.

Map of the Bahama Islands - Samuel Thornton - c1702

One problem with Samuel Thornton’s reissues of his father’s maps was that flaws an original map from which a reproduction was derived went uncorrected. For example if you look at the header image of the full map, there’s a dark band right down the centre of the map, which persisted in later versions. More importantly, there was probably little or no correction of errors that new expeditions in the area might have revealed. Be that as it may, the Thornton map plays a significant role in the mapping of the Bahama Islands and beyond, and marks the start of an increasing sophistication as the new century progressed.

SEA BISCUITS: THEY REALLY DO CONTAIN DOVES – AND MORE!


Sea Biscuit Close-up, Abaco (Keith Salvesen)

SEA BISCUITS: THEY REALLY DO CONTAIN DOVES – AND MORE!

Recently I posed the question whether sea biscuits, like sand dollars contain ‘doves’. I had one in my hand, it rattled, I took a photograph through its ‘mouth hole’ and the question was answered. Biscuits do indeed contain doves – see HERE for details and comparisons with dollar doves.

Sea Biscuit 'Doves', Abaco (Keith Salvesen)

However, I spinelessly* failed to break open the biscuit to check out the contents more closely. I theorised that, because of the 5-way symmetry of these creatures, there would be 5 doves (which are in fact segmented mouth parts) in a biscuit exactly as with a dollar, and amiably challenged anyone to disprove it. [* biscuits and dollars are types of sea urchin – see what I did there?]

Melissa Ann Guinness from Hope Town has a far more robust attitude to these things and, taking up the challenge, she heartlessly smashed open a sea biscuit from her collection to investigate further. I said I’d publish a correction if my theory was wrong. This is it – though in one arguable sense the theory holds good. It just didn’t go far enough…

In the above picture you can see (a) 4 quarters of a sea biscuit skeleton (b) 10 demi-doves (rather than 5 whole doves) and (c) a small mummified 5-limbed brittle star that was presumably in the creature’s digestive system when it died.

SEA BISCUITS: DO THEY REALLY CONTAIN DOVES?

A couple of years ago I wrote a post called ECHINODERMS, DOLLAR DOVES & PETRIFIED BISCUITS. It dealt with the… fact? rumour? old wive’s tale?… that within each sand dollar test (i.e. the white skeleton) are hidden 5 ‘doves’. You can hear them rattling inside if you shake the dollar… 

Sand Dollar Doves (Keith Salvesen) 6

Sand Dollar from Abaco containing 5 miniature white doves…

I investigated the theory with senior granddaughter, and we broke a sand dollar in half. And as you can see, the answer was undoubtedly yes – there were 5 tiny white doves, thus fulfilling the prediction of the famous ‘Sand Dollar’ poem that contains the lines  “Now break the centre open And here you will release The five white doves awaiting To spread good will and peace”.

Five white doves (in fact, the separated parts of the creature’s feeding apparatus)Sand Dollar Doves (Keith Salvesen) 1

A single dove, a picture of dovelinessSand Dollar Doves (Keith Salvesen) 3

I never thought to extend the experiment to sea biscuits, another object prized by beachcombers. All that changed last month when I picked up a sea biscuit and found that it, too, rattled.

A rattling good sea biscuit

So I turned it over to take a closer look at the underside. And there, unmistakably, was the source of the rattle – some kind of internal arrangement inside the feeding  hole (let us not pause overlong to consider the purpose of the other hole). But it wasn’t conclusively a dove.

So I shook it around a bit (sorry, doves) and zoomed in. And there was a small white columbine-type contraption remarkably similar to those found in the dollar dove. And no, I did not smash open the sea biscuit (it wasn’t actually mine). And no, I didn’t doubt any longer that sea biscuits also contain doves.

SO WILL THERE BE 5 DOVES, LIKE WITH THE DOLLARS?

I predict there will also be five. Both dollars and biscuits have ‘five-way symmetry’ (look on the topside of a biscuit or dollar to see how); and so the mouth (from which the ‘doves’ derive) will have a single part for each of the five sectors, all linked. 

If anyone would like to smash up one of their precious beach finds and test the theory, please feel free. Prove me wrong… and I’ll publish a correction! [Photo please…]

MARK CATESBY, PIONEER NATURALIST: NEW BOOK


MARK CATESBY, PIONEER NATURALIST: NEW BOOK

Exactly two years ago, I wrote about the publication of a lavish limited edition facsimile of Mark Catesby’s renowned work The Natural History of Carolina, Florida and the Bahama Islands in 4 volumes to mark the 300th anniversary of Catesby’s arrival in the New World. Unsurprisingly, the cost of the set was prodigious (a rather nice car) – but only a fraction of the cost of a vanishingly rare original set (a rather nice house). Reader, I didn’t buy one.

Now the CATESBY MEMORIAL TRUST has produced an excellent and inexpensive illustrated introduction to Catesby’s great work that will transport you back through the centuries to the earliest days of natural historical research by Europeans abroad. It’s worth remembering that Catesby antedated the more famous John James Audubon (1785-1851) by a whole century.

Catesby’s signature

The new book has over 40 illustrations from Catesby’s The Natural History of Carolina, Florida and the Bahama Islands. These are paired with relevant extracts from the work, and there is additional commentary. Click on Catesby’s Tropicbird below for a sample of the book.

MARK CATESBY? JUST REMIND ME…

Mark Catesby (1683 – 1749) was a pioneering English naturalist and artist who published his magnum opus based on a number of expeditions he undertook from 1712 onwards. His was the first ever published account of the flora and fauna of North America, and the 2 volumes (with a supplement) included some 220 colour plates of the creatures and plants of land and sea that he had come across. After his travels, Catesby spent some 20 years producing his masterwork and died soon after, perhaps from the sheer effort of it all.

AND HIS RELEVANCE TO THE BAHAMAS IS…?

On behalf of the Royal Society Catesby undertook expeditions, first to Carolina and then more widely in America and eventually in the Bahamas. On these trips he drew and painted detailed pictures of birds, fish, turtles, flowers and corals, many of which are familiar in the Bahamas to this day – and a few of which are included here.

ECHINODERMS, DOLLAR DOVES & PETRIFIED BISCUITS


Sand Dollar Doves (Keith Salvesen) 6

ECHINODERMS, DOLLAR DOVES & PETRIFIED BISCUITS

Echinoderms (Gr. ‘Hedgehog Skin’) comprise a large variety of sea creatures characterised (mostly) by radial symmetry, often five-way. For Abaconians, the most frequently encountered are starfish, sea urchins, sand dollars and sea biscuits. I am going to look at two particular aspects of dollars and biscuits, conscious that my illustrative photos of white objects were stupidly taken against a white background.

DOLLAR DOVES

I’m sure all Bahamians know or are aware of at least one version of the famous ‘Sand Dollar’ poem, in which the various characteristics of the test (the skeleton of the creature) are given religious significance. One verse of the poem may be puzzling: “Now break the centre open And here you will release The five white doves awaiting To spread good will and peace”.

Recently, Senior Granddaughter (10 this week) was looking at some Abaco sand dollars in her unfeasibly huge collection of shells. She picked one up, shook it and it rattled. She said a friend at school had told her that a rattling sand dollar has ‘doves’ inside it, and asked if we could break it open and see. I’ve learnt that it is useless to argue with her – she has the tenacity of a trial lawyer – so we did. This is what we found.

PETRIFIED BISCUITS

In common parlance ‘petrified’ is an extreme version of ‘terrified’. Literally, it means ‘turned to stone’ (L. Petrus, a rock). It is descriptive of a state of fossilisation, where an animal skeleton or dead wood or plant matter turns over aeons into stone. Undaunted by her Doves discovery, SG (a most inquisitive girl) also discovered a box containing random stones and fossils. She found these two items:

FUN FACT

Florida has an unofficial but proposed State Fossil, the ‘Sea Biscuit (Eocene Age)’. I didn’t know it before, but it turns out that around 40 States have State Fossils. Whatever next? State Bacteria?

SO HOW OLD MIGHT A PETRIFIED BISCUIT BE?

The fossil biscuits I have looked at, from Florida to Madagascar, are said to come from three specific historic epochs – from the oldest, Jurassic (145m – 201m years ago),  to Eocene (34m – 56m) and Pleistocene (0.01m – 2.6m). 

HOW DOES THAT HELP ANYBODY? BE MORE PRECISE

By all means. Here is an excellent Geochart that gives an idea of the time span. A Jurassic sea biscuit would be more than 145m years old. So maybe the next plan should be to take the 2 petrified sea biscuits plus SG to a museum to see if we can get an idea of their age…geotimescale

MARK CATESBY: PIONEERING NATURALIST OF EARLY c18

There’s been (yet) another abrupt side-swerve away from a topic I’d intended to post about, resulting from a newspaper article I read over the weekend. This concerns what was gushingly described as “the ultimate coffee table book”, a facsimile of Mark Catesby’s renowned work, The Natural History of Carolina, Florida and the Bahama Islands.

Catesby (1682 – 1749) was a pioneering English naturalist and artist who published his magnum opus based on a number of expeditions he undertook from 1712 onwards. His was the first ever published account of the flora and fauna of North America, and the 2 volumes (with a supplement) included some 220 colour plates of the creatures and plants of land and sea that he had come across.

Catesby’s growing fame as a botanist led to his undertaking expeditions on behalf of the Royal Society to collect plants and seeds in Carolina. He widened his researches both in America and to the West Indies, collecting plants and fauna as he went and sending them back to England. Among other discoveries, he was one of the very first people to observe and record the occurrence of bird migration as a twice-yearly phenomenon.

Eventually, in 1726 Catesby also returned to base and set about writing up his findings and painting what he had seen. He learnt how to etch printing plates, and gradually the illustrations became more sophisticated, starting without backgrounds then including plants with the animals and birds. The whole project took him some 20 years; quite soon after completing it, he died.

WHERE IS THE ORIGINAL WORK NOW?
 
Catesby’s original drawings were bought by King George III for £120 (a very considerable sum in 1768 – my quick attempts to discover how much suggest ± £200,000) and have remained in the Royal Family ever since. This treasure is kept in the Royal Library of Windsor Castle, the property of HM QE2, though it is occasionally exhibited elsewhere. Later facsimiles of the original were produced, of which some 50 survive today.

The cost per set? A stonking £39,500 ($61,330). Now this may sound a great deal of money for a modern copy of an old book and it undoubtedly is. But here’s the Christie’s Auction catalogue entry for one of the early facsimiles. Mmmmmm.

Delphi afficionados, especially any who have stayed in Room 1, may recognise 3 of the illustrative images I have chosen – the Spindalis, the Bananaquit and the Grassquit. No, I don’t mean the actual species, I mean that Catesby prints of them are tastefully hung on the walls. I can never decide which of the 3 is my favourite…

ABACO’S FORGOTTEN LIGHTHOUSE: THE “OLD LIGHTHOUSE”, LITTLE HARBOUR


ABACO’S FORGOTTEN LIGHTHOUSE: THE “OLD LIGHTHOUSE”, LITTLE HARBOUR

Little Harbour Abaco, Aerial View -Simon Rodehn annotated

Little Harbour Abaco, Aerial View (Simon Rodehn)

There’s relatively little that a casual investigator can discover about the ruined lighthouse at Little Harbour, Abaco. This hurricane-damaged wreck is Abaco’s third and largely unknown light, after the icon on ELBOW REEF and the desolate but romantic HOLE-IN-THE-WALL that stands on the southern tip of Abaco, down 15 miles of dodgy track through the National Park. Two specific sources of information begin our tour of the “Old Lighthouse at Little Harbour.

Extract from ROWLETT LIGHTHOUSES OF THE BAHAMAS

“LITTLE HARBOUR Date unknown (station established 1889). Inactive. Ruins of a 1-story concrete keeper’s quarters, known locally as the “old lighthouse.” A modern steel framework tower carried an active light until it was blown over by Hurricane Sandy in October 2012; Trabas has Darlene Chisholm’s photo of the toppled light. A photo and a very distant view are available, and Bing has a satellite view. In an aerial view of the harbor, the light is on the peninsula at upper right. Located at the entrance to Little Harbour, about 25 km (15 mi) south of Marsh Harbour, Great Abaco Island. Accessible by a short walk to the end of the peninsula sheltering the harbor. Site open, tower closed. Site manager: unknown. ARLHS BAH-021; Admiralty J4576; NGA 11808.”

The “Old Lighthouse” – Little Harbour, Abaco

Abaco Escape  – Sandy Estabrook’s essential GUIDE TO THE ABACOS

Often overlooked is (or should we say was) the “Old Lighthouse” as it is called. It was established in 1889 at the entrance to of Little Harbour channel, the southern entrance to Abaco Sound. Once it was a manned light, with the lighthouse keeper and his wife being the only inhabitants of Little Harbour. Of course the keepers are long gone and so is most of the house. The light tower was converted to solar in modern times but was dealt a devastating blow by Hurricane Floyd in 1999. Access is via a path which starts from the shoreline and winds up the hill through seagrapes and bush. Few people venture up here these days. If there is a big ocean swell running, walk down to the cliff top in front of the lighthouse, where you’ll find a blowhole known as the Dragon. Depending on swell height, it could be roaring, snorting and shooting out clouds of spray. Sandy Estabrook

Note the steel frame tower on the right, a structure replacing the old light destroyed by Hurricane Floyd in 1999; and itself toppled by Hurricane Sandy in 2012

LOCATION

In the header image, the location of the Light, looking very roughly north, is shown as a grey pimple on the eastern peninsula that forms the Little Harbour bay. There is no other building in this area. Below are some additional aerial maps showing the path to the Light and its relative remoteness. It is not covered in the wonderful book on Bahamas lighthouses by Annie Potts entitled “Last Lights” (2011, Fish House Press). I surmise that this small Light was more of a beacon to pinpoint the location of the entrance to Little Harbour, and perhaps to enable triangulation with the large lights at ELBOW REEF and HOLE-IN-THE-WALL.

“GLIMPSES OF LIFE ALONG A CORAL REEF” A c19 NATURALIST VISITS ABACO


GLIMPSES OF LIFE ALONG A CORAL REEF by F. H. HERRICK

This post is aimed at those with a particular interest in the flora and fauna – especially avifauna – of Abaco and its Cays. It is a naturalist’s account from 1886 of an expedition to Abaco, interspersed with a few line drawings. It’s an easy read if you are interested in Abaco, its history, and the state of natural life on the islands 125 years ago. Those who have come to this site for the photos and / or even the occasional jest are warned to expect neither. However, to tempt waverers I’ll highlight below (by way of a quiz) some intriguing aspects of the 9-page article. I have had to edit it to correct the many ‘literals’ in the open-source material; however the c19 spellings are retained. I’ve also added coloured subject-matter codes as follows: PLACE NAMES; BIRDS; PLANTS; FISH; CREATURES

In 1886, Herrick visited Abaco with a party of naturalists. This trip predated by 3 years the publication of Charles Cory’s groundbreaking ‘Birds of the West Indies‘. There would have been scant readily-available published material about the natural history of the Bahamas, let alone of Abaco itself. Herrick and a friend left the main party and went on their own wider explorations of Abaco with two local guides. Herrick recorded their findings, which were subsequently published in ‘Popular Science Monthly‘ in 1888. In Herrick’s wide-ranging account of the adventure you will find the answers to the following 15 questions. If any one of them whets your appetite to read this historic account, press the link below the quiz!

  • What fruit might you have found growing in fields on Abaco in 1886?
  • What was the local name for the perforated rock at Hole-in-the-Wall?
  • What is an “egg-bird”?
  • What was causing “the gradual extermination” of flamingos?
  • What were “shanks” and “strikers”?
  • To what human use were Wilson’s Terns put?
  • How many eggs does a tropic-bird lay?
  • What law prevented the shooting of tropic-birds, and indeed any other bird, by naturalists?
  • What sort of creature is a “sennet”?
  • Which was rated the better for eating – grouper or ‘barracouta’ (sic)?
  • Who or what is or are “grains”?
  • What common creature had a burning touch like a sharp needle?
  • What bird was reckoned to have the call ‘loarhle-ee’ ?
  • What – or indeed who – was described as a “pilepedick”?
  • What creature laid 139 eggs?
