Well, it’s a shame that in my homespun way I had to press ‘Publish’ when I meant to press ‘Preview’. I just wanted to check if these stills from a video of a massive storm over the Delphi Club at 3.00 a.m. one June night might be worth putting up. This item was for ‘in due course’ and not for now. I’d just decided that they aren’t really worth it, when I realised what I had done. So I may as well go ahead with it… Apologies to all those who are signed up and have got an email just saying “STORM”. I’ll have a word with the management.
Now that this gallery is out there, I should add this storm raged and rumbled for much of the night, with some spectacular rain, lightning and thunder – standing on a balcony watching it was quite an experience. At times the whole bay was momentarily as bright as day. Even brighter. Anyway, here’s the ‘before, during and after’ of a fork lightning bolt. I can’t make out if it’s true that lightning starts at the bottom, but I think it may be sky and earth near-instantaneously.
An informative ‘basic primer’ about lightning can be found at the National Severe Storms Laboratory (part of NOAA)CLICK===>>NSSL/NOAA
This very short time-lapse video was posted on the always informativeABACO SCIENTIST website administered by Craig Layman of FIU (Florida International University). The site benefits from the wide knowledge of a variety of contributors in many different fields. As it says, “Abaco, just like all of the Bahamian Islands, hosts a wealth of natural wonders. From parrots to whales to blue holes to mangrove wetlands, it is no wonder that scientific research is thriving on the island. The Abaco Scientist is intended as your one-stop source for all things science on Abaco and throughout The Bahamas“.
The coral reefs of Abaco and the Bahamas (as elsewhere) are vital yet vulnerable eco-systems. The adverse effects of global warming (or however you describe it if you shy away from that specific term) are increasingly evident. To that damage can be added a slew of other major threats to coral survival – and to the marine life that thrives on the reefs. There are a number of research projects in progress in the Bahamas into the effectiveness of artificial reefs as a means of conservation of the ecology of reef waters. One of these is by FIU undergraduate student Martha Zapata. In her words, “We have recently been capturing time lapse video of the artificial reefs at night. Many reef fishes, like grunts, will leave the reef around dusk to forage in the nearby seagrass beds during the night. We wanted to be able to observe the fish on the reefs without influencing their behavior, so we used infrared light (which fish cannot see) to illuminate the reef. The image sequences have shown a stark difference in fish abundance from day to night. Also, we have been able to observe some of the more cryptic organisms that have made these reefs their home. Usually masters of disguise, urchins roam about the surface of the reef. Look out for the banded coral shrimp and crab that crawl up the side of the reef to graze on algae and detritus while the fish are away. Even a moray eel makes an appearance near the end!“
Besides specially constructed artificial reefs, other man-made objects provide good foundations for an artificial reefs and marine life – in particular, wrecks. There are many of these in the low waters of the Bahamas, some centuries old, others recent. Fred and Melinda Riger of Grand Bahama Scuba, Freeport, take their diving schools to wrecks because of the profusion of marine life that gathers around – and indeed inside – them.
TULIP SHELLS & SUNRISE TELLINS: MORE SHELL TREASURES FROM ABACO
Here are two contrasting shells from the Delphi Club collection that has been haphazardly accumulated over the last 3 years or so. The first post in this shell series was about SEA URCHINS & SEA BISCUITS
TULIP SHELLS Fasciolaria tulipa
The term ‘Tulip snail’ includes 3 related species of sub-tropical gastropod worldwide, of the genus Fasciolaria. They are medium-sized predatory molluscs that breed throughout the year in warm waters. Their reproductive lives deserve some attention, if they will pardon the intrusion.
Research by the Smithsonian Marine Station Fl. reveals that the male’s penis is to be found on the right side of its body, directly behind its head… When they mate the (larger) female stays in an upright position on the sand while the male ‘flips over’ to align the apertures of both shells, before inserting the penis into the female (RH comment: the research is not specific about precisely where the female keeps her own genitals). Once joined, snail pairs may remain locked together for up to 2 hours, even when being watched by researchers. They have plenty of stamina: mating may occur several times in one season, and individual tulip snails have been observed to mate up to 3 times in a single week. Respect!
SUNRISE TELLINSTellina Radiata
I included these pretty shells, with their striking pink radials, in an earlier postBEACHCOMBING BIVALVESThe ones shown here are larger specimens. The hinges (muscles) are very delicate, and in these shells the two halves of the shells have separated. STs are not uncommon, but these are the largest I have come across (I realised after I had taken the photos that I should have used a coin for comparison…). They grow up to about 7 cms, and these ones were that length, or very nearly so.
I can’t assist with their sex lives I’m afraid, which may well be completely conventional, dull even. However, as I discovered when I previously researched these shells, “in most countries it is illegal to bring back these shells from holidays”. To which I can only repeat my comment: Whoops!

22.00 GMT Latest news: Hurricane Isaac has just been downgraded to a Tropical Storm (I realise that for those caught up in the heart of flooding, damage and widespread outages, this may be of little practical comfort – but it is perhaps some encouragement for those further north in the path of the storm).
18.00 GMT Some pictures are now coming out giving an idea of the ferocity of the storm. I’ve assembled a short gallery from Reuters, AP/Getty and similar news resources, which I will add to as and when…

NOA SATELLITE IMAGE AUGUST 29th
Noon GMT The latest Wunderground tracker map for Hurricane Isaac shows the storm’s current position and its subsequent path, decreasing to tropical storm and then tropical depression as it sweeps northwards through Arkansas. The eastwards tendency, noted previously, is now pronounced with the storm predicted to turn towards Missouri and Kentucky.
09.00 GMT Having had many hundreds of hits for this storm post, including a great many from the southern coastal states of the US, I am posting some further information about Hurricane Isaac today, as the storm rages over New Orleans and more widely across the state.
I have been wondering about the New Orleans flood defences that are constantly referred to in news reports, so firstly here is a clear map of the situation showing the reinforcement since Hurricane Katrina
Here is a satellite video of Hurricane Isaac approaching the US coast, taken over two days. It vividly shows the development in the Gulf of Mexico from a “disorganised” tropical storm into a swirling, concentrated hurricane-force storm, with the eye becoming visible as it approaches the coast.
Finally (for now) this is the astonishing view from a space station, giving an idea of the storm’s extent

TS ISAAC STORM TRACKING: LATEST UPDATE 09.00 GMT
Here is this morning’s (GMT) tracking map, with the storm in the Gulf of Mexico, still drifting westwards. Predicted landfall is now mainly on the Louisiana coast. The most significant change overnight is that the Cat 2 prediction has been downgraded, so that the max expected strength is Cat 1
The satellite picture shows Isaac thickly covering the Gulf of Mexico with dense cloud. The coloured markings to the right show the data recorded by the NOAA Hurricane Hunter flying on the eastern edge of the storm (where the winds are less)
Since this is a Bahamian-based blog (with close Florida connections) Isaac’s current position makes this a suitable moment to return to the main business of Rolling Harbour – the wildlife of Abaco. At exactly this time last year, Hurricane Irene was passing directly over Abaco, with the eye going right over HQ at the Delphi Club. The northward passage of Isaac has of course affected the weather there, but it has been spared the ferocity of 2011. We’ll be thinking of course about all those in the US in Isaac’s path when landfall is made shortly
AUGUST 26
I have concentrated for obvious reasons on the projected path of Isaac with special reference to its proximity to the Bahamas in general, and Abaco in particular. I may have given the impression that the continuing westward movement of the storm’s path has meant that Abaco would enjoy glorious dawns, wonderful sunny days and spectacular sunsets. Not so, of course – the side-effects of the storm continue laterally for large distances. It’s lunchtime on Abaco now, and a message from Brigitte Carey on Tilloo Cay says simply “Yes, its nasty here – lots of wind and rain!”

Laughing gulls. Amusingly raucous and raucously amusing. Unless, maybe, you are living right next to a breeding colony during a collective fit of hysterics. These gulls, Leucophaeus atricilla, will be familiar to anyone on the Atlantic coast of North America; in the Caribbean; and further south to the northern coastal areas of South America. In winter, their migration pattern simply involves relocating to the southern parts of their range. They are easily recognisable in the breeding season by their smart black caps, though this fades in winter. And by their unmistakeable call, of course. Immature birds tend to be darker than adults. They breed in large colonies, each female laying 3 – 4 eggs. And like most (all?) gulls, they’ll eat pretty much anything.
Laughing Gull Conservation Status
We saw – and heard – plenty while bonefishing on the Abaco Marls in June. I took some rather grainy distance shots, as they tended to fly off as the skiff was slowly poled towards them. This gull has found a good vantage point for some quality preening among the mangroves.
The pair below stayed put, and watched our gradual approach with suspicion that turned into noisy protest as we poled past them. I presume they were defending their territory – probably a nest site nearby.
I took a very short video just before they flew off as we drifted by. Apologies for the sound of the breeze – I’ve no idea if it’s possible to reduce the background noise while retaining the bird call. Listening to online bird sound clips (e.g. on the excellent Xeno-Canto) I think not. Or not without expensive editing equipment of a complexity I can’t face…
[vimeo https://vimeo.com/48076405]
And here (thanks, Don Jones @Xeno-Canto) is what laughing gulls sound like when one of them has told the one about the bonefish and the shrimp…
It’s good to look beyond the immediate area of Abaco and the Cays when the occasion calls for it – for example, more good news about the BMMRO’s painstaking research and careful protective monitoring of the very small West Indian Manatee population in the Bahamas. I’ve written before about these gentle, unhurried, curious creatures and their vulnerability – particularly to man’s usage of their natural habitatCLICK ===>>>MANATEES
Kendria Ferguson’s story below shows just one aspect of the BMMRO’s commitment to the conservation of the cetaceans and sirenians in the seas around Abaco and beyond. The Manatees have excited the interest of the whole local community including the schoolchildren. If you have ever been moved by the sight of dolphins in Marsh Harbour or whales further out to sea, you can be sure someone is keeping an eye on their well-being. You might even be moved to help this important conservation work, in which case CLICK ===>>>HERE
KENDRIA’S REPORT
Adult female manatees are considered sexually mature at 6-10 years of age and have a gestation period that lasts up to 13 months. The first two years of a calf’s life is spent with its mother. During this time they are taught where to find food, fresh water, warmth and shelter. Generally, after two years the calf separates from its mother. This separation is known as ‘weaning’.
On the 14th of June 2012 Argos satellite locations received from both Rita and Georgie’s satellite tags indicated that they were no longer traveling together. Georgie had been weaned. Georgie was born on the 25th June 2010, therefore Georgie was now old enough to survive on her own in the wild
Georgie fitted with a paddle belt around the base of her tail. A flexible nylon tether is then attached to this belt with the satellite tag, which floats when it’s near the surface.Photo provided by Jim Reid-USGS Sirenia Project
After tracking Rita and Georgie for the last three months, it was hard to fathom a two year old being old enough to take on the world. But like they say – mothers know best!
Rita and Georgie fitted with satellite tags
Rita and Georgie were released in Great Harbour Cay (GHC) on April 19th of this year. They travelled to Nassau during Hurricane Irene (late August 2011) from Spanish Wells, Eleuthera and ended up in Nassau harbour. Concerned for their safety, The Department of Marine Resources gave Atlantis-Dolphin Cay permission to capture the animals and house them until a decision was made as to their release. After spending over twenty-five weeks in captivity, scientists feared that Georgie would be weaned before she was returned to the wild and given the opportunity to learn how to survive in her natural habitat. The mother-calf pair was transported to The Berry Islands on April 19th, where they were released and fitted with VHF data log satellite tags.
A map showing areas visited by Georgie pre-weaning and post-weaning
There are four resident West Indian Manatees (Trichechus manatus) residing in Great Harbour Cay, Berry Islands. Notably, an adult female, “Gina” (known previously from Florida), has been residing in Great Harbour Cay since 1999. Since then she reportedly has had 3-4 calves and is currently accompanied by her female calf, JJ, which was born in the late winter of 2011.
Within Rita’s and Georgie’s first week of being released they travelled over 50 miles around the east coast of GHC to as far south as Ambergris Cays and back into the harbour where they were released. During the winter months, Floridian West Indian Manatees (Trichechus manatus latirostris) travel vast distances in search of warm waters. So it isn’t uncommon for these agile species to explore the shallow waters in which they inhabit.
Georgie is now re-visiting important habitat areas she visited in the past with her mother. Since their separation in June, Rita and Georgie have been seen together in the harbour by the local community.
Scientists will continue to monitor Georgie’s movement patterns around The Berry Islands throughout the hurricane and winter seasons. This data will assist us in developing a management plan for manatees in The Bahamas.

SEA URCHINS & SEA BISCUITS – BEACHCOMBING TREASURES ON ABACO
It’s time we had some more shells and other beach treasures on these pages. In the absence of star Abaco beachcomber and blog-contributor KASIA I have taken a closer look at the Delphi Club collection. This has been casually accumulated by the Club, its members and guests during the past 3 years whenever a good specimen has been encountered, and is displayed in the Great Room. The first items to catch my eye were the ECHINODERMS, a family that includes sea urchins, sand dollars, sea biscuits and star fish. Their sun-bleached tests are often found, though in my limited experience the larger they are, the rarer. The link above is to the Wiki-blurb, which has the unpromisingly daunting heading “This article may be too technical for most readers to understand…”. Now there’s a challenge!
First up is a very large SEA URCHIN, a thing of great delicacy and fragility that weighs next to nothing. I have never seen a bigger one. Looking at the fine detail, it is hard to believe that such perfection of symmetry and intricacy can exist in a creature so very painful to tread on.
This SEA URCHIN is smaller, with more prominent nodules and a much more random pattern – reminiscent of a cartoon of some distant white planet. It has cast a fine knobbly shadow.
SEA BISCUITS have similar five-way symmetry to their first cousins SAND DOLLARSbut are generally pebble-shaped rather than disc-shaped. I have included 2 close-ups to show the fine details of the pattern – almost like lace-work
This SEA BISCUIT is a different type, with the 5 radials reaching right round it. For some reason it only has 4 and not 5 small holes (as one might expect) at the centre. Unlike SAND DOLLARS they tend to be more oblong than round.
A few weeks back, I wrote a post called ‘LAND CRABS: HOW TO STALK & WRESTLE THEM‘. It features stills of famed Abaco nature guide Ricky Johnson in a face-off with a land crab at Bahama Palm Shores. I noted that the large, heavy claw of these crabs is in fact the less worrying one, being used to intimidate and to grip. It’s the small claw that you need to watch out for…
I have now sorted out an annoying camera card v Mac format incompatibility problem (well, $30 of software has dealt with it. Dear Apple, please make friends with the Panasonic Lumix asap) and to my great surprise I find that I took a video of Ricky and a land crab that perfectly demonstrates the claw point. He did mess with the large claw, but he wisely left the small one well alone…
The footage starts with Ricky’s trademark laugh to get you into the right spirit (it’s impossible to go on one of his Eco-Tours and not have fun while learning). The volume of the commentary drops off a bit halfway through. I haven’t found the gizmo for changing the audio during the video: it’s all or nothing, I’m afraid
[vimeo https://vimeo.com/47535538]
If you want to find out more about Land Crabs on Abaco – including Hermit Crabs – you won’t do much better than to check out the comprehensive account by ‘Bob H’ on Yahoo! Answers ABACO LAND CRAB FACTS
Ricky the guide? Here he is in full-on enthusiastic guide mode, ‘pishing’ for male Bahama Woodstar hummingbirds in low open coppice near Crossing Rocks. He has just had a responding call and is keeping us quiet while he locates the bird
ADDENDUMTragically in the second half of 2012 Ricky developed a horrible disease that spread rapidly and unstoppably. Within 6 months he was dead, not yet 50. His sad passing, and the cruel manner of it, made me wonder if I should take down some of the many posts in which he features. But he would not have wanted that, so I have left them unaltered.
MUSICAL DIGRESSION
Those who braved the video may have wondered about the guitar chord at the beginning and end. A few – of a certain age – may have thought it familiar. One or two may have recognised it as the opening chord of A Hard Day’s Night (Beatles 1964). It is one of the most controversial and interesting chords in modern music, with more theories about its exact construction than you can shake a Rickenbacker 12-string at (as played by George Harrison). There have been more than a dozen claimed ‘correct’ chord identities. According to Harrison, it is in fact simply an ‘F add 9’ chord augmented by Macca’s crucial 5th fret, A string ‘D’ on his Hofner bass. Trouble is, there are half a dozen ways to play ‘F add 9’ at various points on the neck, and most of them don’t sound quite right… But that’s enough about that. Anyone who wants to follow this musical meander further – much further – should click HERE===>>>THAT CHORD
This is the first short video from footage taken in June at Fowl Cay, 2000 acres of protected coral reef waters. This was the start of another great day out snorkelling and island-hopping with dive-diva Kay Politano ofABOVE & BELOW ABACOMarsh Harbour. In due course there will be more videos of fish and coral. There is very slight evidence that lessons have been learned since last year’s erratic novice snorkeler / underwater photographer efforts. Still a way to go of course. The production process has been hampered by a major format problem between my camera chip thingy and the Mac I now use. It told me the data was unrecognisable / corrupted / damaged etc, which was massively disappointing. Then I thought of <<techno-tip>> downloading to an old PC and transferring to the Mac on a memory stick. Problem solved.
This huge swirling mass of (tens of) thousands of small fish confronted me as I round one end of the reef. I’ve never seen anything like it before, except on TV. It was an astounding, dizzy-making spectacle. When I swam into the middle of the shoal, I expected to feel tickled all over – but despite the huge numbers of fish, their speed, and their sudden and apparently random direction changes, I wasn’t conscious of feeling them at all. I assume the commotion resulted from the presence of larger fish feeding on the small ones. Or possibly from my appearance…

Last month there were bottlenose dolphins for Abaco; manatees for the Berry Is. [Hi, Rita & Georgie! – check out their progress on FACEBOOK BMMRO]with a first manatee sighting (I think) off the west coast of Long Island; and quite a few whale reports off the east coast of Andros. I wonder why the whales are all in that area at the moment? Maybe the reports are high for that area because that’s where the whale spotters congregated in July…
STOP PRESSGeorgie the Manatee is now weaned – for detailsCLICK===>>>HERE
STOP PRESS 21 AUGAs a sad coda to these sightings, the BMMRO has posted news of the stranding and death of pygmy sperm whale on Eleuthera
Stranding Event: August 19th, 2012 A blackfish stranded in Eleuthera:
Photos confirmed the species to be a pygmy sperm whale. The animal stranded alive but later died. Many thanks to Tom Glucksman and his wife for their efforts in providing pictures and getting a skin sample, which will allow us to get even more information about this animal
I recently posted photos of an unknown aggressive-looking INSECT that I found in the coppice on Abaco. I could only get a partial shot of it, and I wondered whether to try to reach it and get a more complete shot. Perhaps I could have stroked its dear little back… or tickled its cute feelers…I received various ID suggestions, ranging from the entomologically broad hedge-bet “big black beetle” to a more precise “black praying mantis”. I contacted the BNT to see what they thought. I’m glad I did. It turns out that this creature would be the hardest bastard insect on Planet Bastard. It is a SPIDER WASP of the Pompilidaefamily, almost certainly aTARANTULA HAWK aka PEPSIS WASP. It’s fortunate that I didn’t try to pet it or keep it in a matchbox. Note, for start, the scary eating apparatus… and it’s not nibbling leaves as I had thought, but chopping up a small insect. The leg claws and barbs are for pinning down its prey. You would not believe how unpleasant these little buddies are – and that’s before we even mention the sting…
SPIDER WASPS
These wasps (family name Pompilidae) are known in some countries as “horse-killers”. There are many species around the world, with 6 subspecies, one of which being the Tarantula Hawk or Pepsis Wasp – so-called because it hunts tarantulas and uses them in a most ingenious and cruel way…NBTheBNThave rightly pointed out that these insects are unaggressive to humans. If you leave them alone, they will spare you. I’ve also read “The tarantula hawk is relatively docile and rarely stings without provocation” Now read on to see if it’s worth provoking one
SCARY CRITTERS & LIVING LARDERS
SPIDER WASPS are ‘Solitary’ insects that feed on ground spiders/ tarantulas by stinging them to paralyse them, then eating them. The females also make use of spiders for breeding purposes. They build a nest in a burrow, find a spider, paralyse it with their sting, drag it to the nest and lay a single egg on its abdomen. Then they seal up the burrow.
When the egg hatches the larva chews a hole on the spider’s abdomen and enters a living larder. It gradually eat its host as it grows. The spider’s vital organs are left till last, so that the spider stays alive as long as possible until the larva has reached full-size. After several weeks, the larva spins a cocoon and pupates (often over winter). Finally, the wasp becomes an adult, bursts Alien-like from the spider’s abdomen, and tunnels out of the burrow…
Their hunting improves with experience – the more spiders they eat, the quicker they find, attack & kill them
Males use ‘perch territories’ to scan for receptive females from a tall plant or other vantage point, a behaviour known as HILL-TOPPING
Adult wasps also feed on a variety of plants for nectar & pollen. They may become intoxicated on fermented fruit, which affects their ability to get around (I think we’ve all been there at some time…)
The female Pepsis gets her spider in two main ways: approaching a tarantula causing it to rear up defensively on its legs, thus exposing its abdomen to the sting or
She locates a tarantula’s burrow, using her sense of smell. She tricks the spider into emerging by tweaking the web at the burrow’s entrance or ‘intruding’ (see video below)
The wasp uses her long stinger to stab her prey. The poison rapidly paralyses the spider. She then drags it to her burrow, lays her egg onto the tarantula’s abdomen, seals the burrow and leaves. Job done
The hooked claws and barbs on the wasps’ long legs are weapons for grappling with victims
The stinger of a female tarantula hawk can be up to 7 mm (1/3 inch) long – and the sting is among the most painful insect stings in the world (see below)
Only the females sting (males may pretend to) because the stinger is linked to the ovipositor (egg-laying organ)
You can distinguish females from males by the curled antennae of the female. Mine was therefore female
The Pepsis wasp has (unsurprisingly) very few predators, though roadrunners and bullfrogs may tackle them
Here is a hypnotically fascinating 3-minute video of the life-or-death struggle
SPIDER WASP –v- TARANTULA
THE STING
The sting of these wasps is among the most painful of any insect, though the most intense pain lasts on a few minutes. Entomologist Justin Schmidt bravely submitted himself to the stings of various insects and described this pain as“…immediate, excruciating pain that simply shuts down one’s ability to do anything, except, perhaps, scream. Mental discipline simply does not work in these situations.”
Schmidt produced his SCHMIDT STING PAIN INDEXThe pain scale, based on 78 species, runs from 0 to 4, with 4 given for the most intense pain. Spider Wasps of the species Pepsis – i.e. Tarantula Hawks – have a sting rating of 4.0, described as“blinding, fierce, shockingly electric. A running hair drier has been dropped into your bubble bath”Only the bite of the Bullet Ant (not found on Abaco!) is ranked higher, with a 4.0+ rating, vividly described as “pure, intense, brilliant pain. Like fire-walking over flaming charcoal with a 3-inch rusty nail in your heel”

LIGHT RELIEF
1. In 1989, New Mexico chose the Tarantula hawk wasp as the official state insect. The choice seems to have been left to schoolchildren and I’m guessing here (or gender-stereotyping) but I suspect it was the boys’ choice that won…
2. Tarantula Hawk is a “psychedelicprogressive metal band” from San Diego, Ca. Their short discography includes their debut Tarantula Hawk (CD/LP, 1998); Burrow (Live CD, 2000, self-released); and Untitled. I’ll just check if… OMG!! you can even get these on iTunes… and (OMG!!!) Am@z@n. The cover of their debut provides the perfect ending for this post, vividly depicting the colour and texture of the swirling fiery pain you could experience (and I don’t really mean from listening to the music…)

One of the first images from Mars
CURIOSITY landed on Mars today. This is the best chance yet of answering Ziggy Stardust’s rhetorical question “Is there life on Mars?”, and doffing an astronaut’s helmet to space pioneer Major Tom along the way… Assiduous readers of the blog will both recall that a while ago, the Delphi Club was privileged to be involved in a small part of the ‘Curiosity’ Mars Rover project. It’s a prime example of what one might call “extreme beachcombing…”
“One small part for a space program, one giant chunk of junk for the Delphi beach…” (S Walker)

The episode had a slightly bathetic ending. Initial lack of official interest in the cone, which I personally hoped could then be planted deep in the coppice or pine forest for future generations to discover and wonder about, suddenly changed. In due course a team of astro-science persons (in a large black truck and white protective suits, I’d like to believe) came and took it away. This forestalled my other idea: cutting it up into hundreds – or thousands – of small pieces and selling them on eBay (possible in aid of the Abaco Parrots). A 12 foot cone of gleaming heat-resistant secret Abaconite space material. 5000 tiny pieces @ $100 each… Hmmmmmmmmm
LA SAGRA’S FLYCATCHERMyiarchus sagrae is anon-migratory bird quite frequently seen in the Abaco pine forest and scrubland. It is resident throughout the year on Abaco, as elsewhere within its distribution range (see map below) – also occasionally found as a vagrant in southern Florida. It is a ‘tyrant flycatcher’, a passerine species found throughout the Americas that includes kingbirds, pewees and phoebes.
The conservation status of this flycatcher is ‘Least Concern’
The LSF’s natural habitat is subtropical forest and rough scrubland. It builds its nest in a tree cavity or similar natural hole, and usually lays a clutch of two to four eggs.
Adult La Sagra’s Flycatchers, unlike many avians, are very similar in appearance in both sexes.
As the name suggests, the species is primarily insectivore, fly-catching in the undergrowth and low scrub. However these birds also eat berries and seeds. Their call is a high pitched single or double noted sound described as ‘wink’. Here’s an example from the Bahamas by Paul Driver @ Xeno-Canto
And who or what the heck was La Sagra? The answer is: multi-talented Spanish botanist Ramón Dionisio José de la Sagra y Peris(1798–1871), who was also a writer, economist, sociologist, politician, anarchist, and founder of the world’s first anarchist journal El Porvenir (“The Future”). At one time he lived in Cuba and became director of Havana’s Botanical Garden; his name lives on arguably more significantly in ornithological than in anarchist circles (actually, an ‘anarchist circle’ must surely be a contradiction in terms…)
I note in passing that La Sagra is a provincial area in Spain, an Italian festive celebration, a chocolatier, or a small comet – all of which meanings may have to be negotiated online before you get to the flycatcher…
Ramón Dionisio José de la Sagra y PerisFinally, to continue with the recently introduced avian philatelic theme, here are stamps from the Cayman Islands and Cuba featuring the La Sagra’s Flycatcher. The Cuban stamp commemorates the death of Juan Gundlach, the man who chose La Sagra’s name to bestow on this bird
This is a well-know bird (Loxigilla violacea) that can be seen on Abaco all year round. With their scarlet bibs and eyebrows, the males are a cheerful sight in coppice or garden. The females are paler brown, with orange accessories.
While still officially rated as a species of ‘Least Concern’, a measurable fall in population in recent years has seen them nudging towards ‘Vulnerable’.

Antillean Bullfinches enjoy garden feeders – and their larger size means that they are higher up in the pecking order than the black-faced grassquits and other small birds
They are one of the many popular Bahamian bird species to have featured on postage stamps – in fact they scooped the high-value $10 stamp in 1991 and the $5 stamp in 2001
This post is intended in part as a celebration of passing the 50,000 hits mark today. So much interest in the wildlife of one small island – thanks to all those who have visited during the last year or so
The first image below is of the handsome locally hand-carved pineapple that surmounts the roof of the Delphi Club, Abaco. The fruit lost a few leaves in Hurricane Irene last August, which scored a direct hit on the Club. As posted on theABACO FACTS page (under RANDOM main menu) “the precise Longitude & Latitude coordinates of the Pineapple [on] the Delphi Club roof are respectively –77.1787834167480 &26.20450323936187“. But why is it there? Time for a Short Voyage around the Pineapple…
PINEAPPLE FACTS TO ENLIVEN YOUR CONVERSATION
HISTORICAL & SOCIAL CONTEXT
Brought back to Europe by Christopher Columbus in 1493 on his return from his second voyage
Taken on long voyages as a protection against scurvy and because of its long life
By the c17 royalty & aristocracy grew them in hot-houses (or rather, their gardeners did). King Charles II tried one, an event so important it was recorded by the Court painter Hendrik Danckerts
By c18 considered a great delicacy and a status symbol of wealth, often the centre-piece of a feast.
If you couldn’t afford to buy one, you could rent one and return it afterwards. Someone richer than you would then buy it.
Pineapples were grown in pits of fermenting manure. In England Queen Victoria was not amused and soon put an end to that unpleasant nonsense
In the c19 pineapples were one of the most significant exports from Abaco
The Earl of Dunmore built a huge pineapple folly in Scotland in 1761, which you can stay in (We have. It’s a lot of fun)
CULTURAL SYMBOLISM
Pineapples symbolise welcome and hospitality, placed at the entrance to villages or plantations. The tradition spread to Europe where they were carved as gateposts; staircase finials; and incorporated into wooden furniture (including bedposts at the Delphi Club)
Seafarers put pineapples outside their homes on their return to show that they were back from their travels and ‘at home’ to visitors
An expensive fruit to grow & to transport; remained a luxury until the arrival of steamships
Their costliness made them status symbols / indicators of wealth and rank. Displaying or serving pineapple showed that guests were honoured
In the 1920s the grandest dinners apparently needed both “a pineapple and Lady Curzon” (I have been asked whether this is Interwar Period code for some sort of disreputable activity… I need to check)
The future Queen Elizabeth was sent 500 cases of canned pineapple as a wedding present from Australia. She asked them “Hev you come far?” Prince Phillip’s reaction was – apart from the word ‘pineapple’ – unprintable
In the play Abigail’s Party (Mike Leigh) pineapple chunks on cocktail sticks were used as a plot device to highlight the desperate social ambitions of a hellish hostess trying to impress & outclass her guests
A 1930s ad promised that by baking a pineapple pie a wife would make her man “smack his lips in real he-man enjoyment” (NB This may not work so well in the 2010s)
By Appointment to HM the Queen
ARTS & CRAFTS
Used on Wedgwood pottery designs as early as the 1760s; others soon followed suit
Became widely used decoratively as a motif for gateposts, weather vanes, door lintels, wallpaper, table linen & curtains, and incorporated into furniture
Featured in still life paintings as a crowning example of opulence
Depicted in plant and fruit studies, for example these by Johann Christoph Volckamer, very early c18
Featured in music e.g. Pineapple Rag (Scott Joplin); Pineapple Head (Crowded House); Escape – The Piña Colada Song (Rupert Holmes); Pineapple Express (Huey Lewis); Pineapple (Sparks)
Used as a motif on shutters in Marsh Harbour
The Men’s Singles Trophy at Wimbledon is a silver gilt cup with a gilded pineapple on top of the lid. These days its meaning is “Welcome back, Roger!”
10 MISCELLANEOUS PINEAPPLE CHUNKS
The cocktail Afterglow is 1 part grenadine, 4 parts orange juice & 4 parts pineapple juice on ice
Piña Colada is rum, coconut milk & crushed pineapple. Omit the rum for a Virgin Colada
It is impossible, for chemical reasons, to make jelly with fresh pineapple
“Pineapple heat” was once a standard marking on thermometers
A pineapple grows as two interlocking helixes (8 one way, 13 the other – each being aFibonaccinumber)
A pineapple will never become any riper than it was when harvested
Workers who cut up pineapples eventually have no fingerprints – a gift fact for crime writers
Pineapple stems are being tested for anti-cancer properties
Pine Apple, a small Alabama town full of pineapple symbols, was originally named “Friendship” but there turned out to be another town called that, so they changed it
Features on the Bahamian 5 cents coin…
…and (later addition) a $1 stamp

THE PINEAPPLE – KING OF FRUITS
If you want to find out more about pineapples, their history and social significance, you should be able to pick up a copy of this book on Am@z%n, Abe or ALibris for a few dollars
“What?” I hear you cry, “you’ve managed a whole page about pineapples without mentioning modern advertising”. Shall I do so now? The man from Del Monte, he says YES
Sources: Own ideas + some magpie-thieving-borrowing from a variety of online sources, many of which contain identical info and / or quote from the above book. Hope everyone is comfortable with that…
NB Not every fact above is strictly 100% true, so expect to be challenged if you roll one out. In particular Prince Phillip is of course naturally docile and gentle-mouthed…

AN ABACO INSECT IS BUGGING ME – WHAT IS THIS CREATURE?
There I was, walking slowly along the Delphi drive trying to locate some small chirruping bird in the coppice – close at hand, chatty, but invisible among the leaves. Then I saw this creature. It’s not an insect I have ever seen before, and I haven’t been able to find out what it is. It’s probably something elementary – an ‘Abaco Black Orange-Feeler Beetle’ – that is familiar to everyone. Except me. I’d just like to know. Any help out there? A response via the Comment box below would be appreciated!
This insect has some interesting features. The feelers are segmented, with 9 joints, so that in close-up the apparent smooth curve is not a perfect one but an articulated series of ‘straights’. It has 4 toes for gripping, and leg spines. It appears to be a voracious leaf-eater. And it can scratch its head. Overall, it looks aggressive and somewhat alien. Imagine if these things were the size of a potcake. Coming at you…
Conchs are among the most familiar of all shells. On Abaco they are everywhere: in the sea, on the beach, used ornamentally in gardens, piled up wherever conch is on the menu… (basically, anywhere serving food)
Conchs have other uses besides being a staple food. They provide sought-after pink pearls. Only about 1 conch in 10,000 has a pearl, so bear in mind that if you miss one during your search, you may have another 10,000 to wade through… Conchs can produce music, of a sort (such as when used enthusiastically by the famous ‘conch-blower’ home-team supporter during cricket Test Matches in the West Indies). They are undeniably decorative on a porch or on a shelf.
Conchs have featured in literature and film. In William Golding’s Lord of the Flies the conch represents power and order. A conch is blown to call meetings of the marooned boys. Its power is symbolised by the rule that you have to be holding it to speak at the meeting (an idea that many – all? – Parliaments could benefit from…)
Ian Fleming mentions conchs in several of the Bond books, all such references being totally eclipsed by the memory of the appearance, in the film Dr No, of Honeychile Rider emerging from the sea, conch in hand. Oh, I see. That’s just men is it? Or (good grief) just me? Anyway, may we all agree amicably that Ursula Andress was a most decorative conch carrier?
CONCH CONSERVATION
The supply of conchs is not infinite. Overfish them, take them before maturity or pollute their habitat and this valuable marine resource depletes – and conchs, as with so many marine species, will become threatened. Fortunately there is a Bahamas-wide conservation organisation with a website packed with interest.
COMMUNITY CONCH is “a nonprofit organization that aims to protect queen conchs in the Bahamas, a species of mollusk threatened by aggressive over-fishing. We promote sustainable harvest of queen conch through research, education and community-based conservation”
“Helping to sustain a way of life in the Bahamas”
Much of the research has been carried out in Berry Is, Andros and Exuma Cays. However the team has recently been based at Sandy point, Abaco. To see some of their work on AbacoCLICK LINK===>>ABACO EXPEDITION
In many past posts I have listed ’10 Essential Facts’ about the topic discussed. In that spirit I have borrowed and slightly edited CC’s conch facts; and added a CC video of a conch’s stately ‘full speed ahead’ progress. NB No zoom…
12 CONCH FACTS
The queen conch is a large edible sea snail native to the coasts of the Caribbean, the Florida Keys, the Bahamas, and Bermuda. Conchs are herbivores – they eat algae and other tiny marine plants
Main predators include nurse sharks, loggerhead turtles, other snail species, blue crabs, eagle rays, spiny lobsters, and other crustaceans
Mating aggregations may contain hundreds or even thousands of individual male and female conchs
Female conchs lay hundreds of thousands of tiny eggs in a sandy egg mass. The larvae emerge after 5 days and may drift on ocean currents for a month before settling in suitable habitat on the sea floor
In their first year conchs live under the sand during the day & come out to feed on the surface at night
A queen conch may take 5 years to reach maturity and can reproduce
They live an average of 7 years, but are known to live as long as 20 – 30 years
Conchs produce natural pearls that come in a range of hues, including white, brown, orange & pink
The conch is listed byCITESas a species which may become threatened with extinction if trade is not tightly controlled
It is now illegal to take queen conchs in the state of Florida due to severe overfishing
80% of legal internationally traded conch is consumed in the United States. The smuggling of conch meat into the U.S. is a significant challenge to conch management in The Bahamas
Queen conch are vulnerable to overfishing because they are (1) relatively slow to grow (2) late to mature (3) aggregate to mate (4) easily harvested in shallow waters
A SPEEDY CONCH
(Conch photos taken by RH / Mrs RH at Sandy Point, Abaco)
This small bird was quite far back – and high up – in the coppice on the Delphi guest drive. The photos were distance shots, so not the best quality, but they do capture the little bird in full song. BGGs have complete white eye rings; males have a dark ‘monobrow’ which can just about be seen in the photo above. In a word, ‘cute’. They sound like this (you may need to wait for the clip (credit: Cornell Lab / RH) to load – or hurry it along by clicking ‘Play’ as it loads):
They build a cup nest on a horizontal tree branch. It’s a modern family unit – both parents make the nest, tend the eggs, feed the young, and teach them manners. They may raise two broods in a season.
BGGs eat insects and spiders, feeding in trees and shrubs. They can hover very briefly, but mainly they catch insects on the wing (‘hawking’). The tail is often held upright while defending territory. Or sometimes just because they can.
All the information you could want on this species can be found at the excellent OISEAUX-BIRDS.COM
STOP PRESSchecking back through my photos, I’ve found a (slightly blurry) distance shot of a BGG. I am adding it because it shows the bird with its characteristically cocked tail, often seen when perching (the bird, I mean)
A very pretty BGG has recently been published on the superb Cornell Lab website, credited to Laura Frazier. It’s so cute – and such a clear image – that it deserves inclusion here
Actually, I say ‘Abaco’ but the most activity – and the most varied, species-wise – is off the southern coast of Grand Bahama. Abaco sightings are also confined to the south, with shows from aPIGMY SPERM WHALEand aBLAINVILLE’S BEAKED WHALEand dolphins in the arc between Rocky Point and Hole-in-the-Wall.
