PUFFER FISH: BAHAMAS REEF FISH (19)

10 PUFFER FISH FACTS TO ASTONISH YOUR FAMILY & FRIENDS

1. Puffers can inflate their bodies in an instant by ingesting huge amounts of water and becoming water-filled balloons.

2. They need a startling form of defence like this (or ‘piscatorial superpower’) because they can’t swim very well.

3. However, a persistent predator will find that they contain a toxin (tetrodotoxin TTX) that is a hundred times stronger than cyanide. One puffer fish has enough toxin to kill quite a few humans. Agatha Christie was unaware of this – had she been, we might have had a classic multiple murder mystery based on the contents of a fish tank… “Poirot and a Fishy Tale of the Caribbean”

4. Selected parts of a puffer fish are a delicacy in some cultures (‘fugu’, in Japan). Trained chefs are used to avoid mass deaths among diners.

5. Sharks are the only species immune to the puffer fish and are not much bothered by a small fish that can blow itself up.

6. Puffers have skin, not scales; most have toxic spines of some sort. Bright coloured ones are probably more toxic than their duller cousins.

7. It’s worth knowing what an uninflated puffer looks like before you try to pet a passing fish and have a toxic encounter.

8. There are more than a hundred puffer species in the world, found where there are warm shallow waters.

9. Noy all puffers are toxic; and some are more toxic than others.

10. I have no idea of the relative toxicity of the 2 puffer species featured here. Sorry about that. Take care!

CHECKERED PUFFER FISH

I photographed some Checkered Puffers at Sandy Point, Abaco last summer. None was puffed up, and I wasn’t about to upset them. The following photos of a small group of puffers were taken from above and not underwater (“no fear”).

I don’t know what species of puffer the one below may be, but I do know I don’t want it in the palm of my hand. I include it from an ‘info for kids’ site to illustrate what the full balloon looks like. I’m wondering if all one needs to deal with them is a pin on the end of a long stick…

ABACO’S 5 ‘PERMANENT RESIDENT’ WARBLERS & A NEW WARBLER ID GUIDE

May 31, 2014 by Rolling Harbour

Olive-capped Warbler, Abaco

ABACO’S 5 ‘PERMANENT RESIDENT’ WARBLERS & A NEW WARBLER ID GUIDE

There are 37 Warbler species (Parulidae) recorded for Abaco. There is considerable scope for confusion between many of them. For a start, by no means all have the helpful word ‘warbler’ in their name. Secondly a great many of the species are to a greater or lesser extent yellow, with sub-variables for gender, age and season. It’s easy to get in muddle. A good place to start ID is with the warblers that are on Abaco all year round. Only 5 species are permanent residents on Abaco and the Cays: Bahama Warbler, Bahama Yellowthroat, Olive-capped Warbler, Pine warbler and Yellow Warbler. I have used images of these to illustrate this post.

Yellow Warbler (f) Abaco

The rest are mostly winter residents, with some being transient visitors passing through on their migration routes. Some are ‘everyday’ birds; some are unusual; and a few are extremely hard to find, the Kirtland’s warbler being the rarest and therefore the most prized sighting of all. I will be returning to the Kirtland’s in more detail in due course.

Pine Warbler, Abaco

At the bottom of this post is a complete list of the Abaco warbler species, with Bahamas bird authority Tony White’s excellent codes indicating (a) when they may be seen; and (b) the likelihood of seeing a particular species (from 1 – 5). First however, news of a great resource for aiding warbler ID, produced by The Warbler Guide. Click on the blue link below to open a pdf with illustrative views of warbler species from several angles, spread of 8 pages. These are the warblers of North America, but you’ll find that almost all the Abaco warblers are featured.

ABACO’S ENDEMIC BIRDS: MAKING A CASE FOR PROTECTION

Bahama Yellowthroat on Abaco – Tom Reed

ABACO’S ENDEMIC BIRDS: MAKING A CASE FOR PROTECTION

I recently wrote a post showcasing the 4 Bahamas endemic bird species found on Abaco: swallow, warbler, woodstar hummingbird, and yellowthroat. You can read it and see some great photos HERE. Sadly, the magnificent oriole, extant on Abaco for centuries, was extirpated in the 1990s. You can still see them but only on Andros; and the population there is barely sustainable – there are only 260 remaining. Still, on Abaco there remain four of the endemic species to conserve and care for.

The Bahamas National Trust BNT has produced 6 brief but informative illustrated ‘cards’ about the Bahamas endemics. They deserve a wide audience, especially in view of the threats to some species for reasons that include habitat loss and increasing development. New Providence lost its subspecies of Bahama Yellowthroat within the last 20 years. Let’s hope that Abaco can hold onto its speciality birds for the future.

“I’M ONLY HERE FOR THE BEER…” ON ABACO

May 27, 2014 by Rolling Harbour

“I’M ONLY HERE FOR THE BEER…” ON ABACO

Strangely, our time on Abaco is usually punctuated at regular intervals by the ingestion of libations of an intoxicating variety. Basically, wine and beer. This has many positive benefits: for example, it has a tendency to make ones own jokes seem a great deal funnier; and it can definitely aid casting confidence for an afternoon of bonefishing… Looking back over some recent photos, I found one I took on the Delphi beach during the ‘Permit Bagging’ week at the north end. I was amused by the sophistication of this shoreline collection of “essentials” belonging to one of the permit casters (RF – you!). The beer was an unsurprising beach-fishing accompaniment – the box of Romeo y Julietas was the main item of interest.

There can be few beers more perfectly named for its surroundings than Sands, although it can be drunk out at sea just as easily…

My own favourite is Kalik – though admittedly after a while my discernment of the subtle differences between the 2 brands may become somewhat dulled

This guy seems to be enjoying his lunch on a perfect day out fishing offshore… Oh! Wait – it’s me…

I enjoyed this imaginative beer-based image posted by Kaitlyn Blair on FB

The title from this post comes from a slogan for Double Diamond beer circa 1970 and the associated excruciating advertising. It caught on, and in almost any social situation at least three people were likely to say “I’m only here for the beer”. Even Garden Parties at Buckingham Palace (where one of the droll wags was, by royal prerogative, Prince Phillip). Here, in all its glory, is the ‘fons et origo’ of the expression…

BANANAQUITS ARE UBIQUITS ON ABACO – AND ÜBERCUTE TOO

BANANAQUITS ARE UBIQUITS ON ABACO – AND ÜBERCUTE TOO

The Bananaquit Coereba flaveola. Permanently resident on Abaco, at the Delphi Club, and in my top ten favourite birds. And everyone else’s, I shouldn’t wonder. With their handsome livery and their cheeky chirping, they can be found almost anywhere. They could equally well be called ubiquits. I had been going to post some recent images of one feasting at a hummingbird feeder, but I found this thirsty palm-forager in my photo folder first, so here he is in all his glory…

Here’s the song of a bananaquit from Xeno-Canto (Paul Driver, Andros) (and there’s a thick-billed vireo in the background)

ABACO WARBLERS: IN SEARCH OF A YELLOW RUMP…

May 19, 2014 by Rolling Harbour

ABACO WARBLERS: IN SEARCH OF A YELLOW RUMP…

I haven’t been very lucky with yellow rumps in the past. This is not normally something one likes to talk about in a public forum… but to be honest I have been longing to get hold of a yellow rump of my own. The warbler Setophaga coronata, that is, a fairly common winter resident on Abaco. I’ve seen them of course. I’ve glimpsed a passing flash of yellow rump. But no YRW has stayed parked in tree with its backside towards me for long enough to permit me to photograph its posterior glory. Ideally I’d have liked a clear, attractive shot like the header image (Dan Pancamo, Wiki). But desperation leads to lowered expectations and plummeting standards. Frankly, this year I’d have been satisfied with any yellow rump. Abandoning my initial plan to apply a yellow highlighter pen to a compliant female grassquit, I bided my time. And suddenly there, at the very top of a tree near the swimming pool at Delphi, was my chance… A pair of YRWs were in evidence.

The tree wasn’t very close to me, and the birds stayed near the very top. My photos were never going to be great. Especially since each bird was meticulous in keeping its rear end out of sight. Then they flew away! However quite soon one was back. This time there were twigs in the way, one of the those little variables that makes camera focussing so enjoyable. But this time I managed to ‘pap’ its derrière… Feeble shots but mine own. As an avian ‘Holy Grail’, a mere yellow rump leaves quite a lot to be desired, I can quite see. It’s on no one’s ‘bucket list’ of birding musts. But now I can move on, release that poor female grassquit and chuck out the highlighter pen.

BAHAMA WOODSTARS NESTING ON MAN-O-WAR CAY, ABACO

May 15, 2014 by Rolling Harbour

BAHAMA WOODSTARS NESTING ON MAN-O-WAR CAY, ABACO

I’ve written before about the somewhat fraught relationship between the 2 hummingbird species of Abaco, the endemic Bahama Woodstar and the resident but non-indigenous Cuban Emerald. They tend not to mix, and the Woodstars tend to fade to areas where there are no Emeralds. Both are found at Delphi, but I suspect the sugar water feeders may play a part in that. Even there, the Emeralds predominate. This is my best recent shot of a female Woodstar on the Delphi drive. I had about 30 seconds to see it, whip out the camera, remove the lens cap and fire off some shots. Then it flicked away into the coppice. All images were useless bar one, which almost worked but won’t stand close scrutiny.

Man-o-War Cay may be quite small, but it seems to be blessed with plenty of Woodstars. They are often quite tame and Charmaine Albury has them nesting round her house annually. I posted about her baby Woodstars from last year HERE. This year they have returned, making their tiny cup nests rather precariously amid the domestic wiring. Here are a few of Charmaine’s nest photos (for which thanks!) for this season.

A female Woodstar on the nest. They lay 2 eggs, which are incubated for around 2 weeks

A fledgling takes flight for the first time, leaving more room for the remaining chick. Note the stumpy little tail

ABACO BIRDS… THAT RUN LIKE THE CLAPPERS

May 13, 2014 by Rolling Harbour

ABACO BIRDS… THAT RUN LIKE THE CLAPPERS

That is, essentially, because they are indeed Clappers. Rallus longirostris to be precise, or Clapper Rails. There are 4 rail species on Abaco, the Clapper being a permanent resident and not particularly uncommon. The others are the Virginia Rail and the Sora, both winter residents and less common (or in the Sora’s case, perhaps more furtive and less easy to find); and the Black Rail, which is generally agreed to be a ‘hypothetical’ for Abaco. That means they are believed to exist on Abaco but there are no confirmed sightings let alone any photos of one. However, last summer while we were taking a truck into the backcountry of South Abaco to locate hard-to-find birds for “The Birds of Abaco” book, the distinctive call of a Black Rail call was heard independently by two people on two different days in two different locations. I’ve heard another report since then. So they are out there somewhere, but keeping their heads down. The first to find one will have a considerable avian scoop!

Let’s start with some fabulous photographs by Tom Sheley. We used the first one in the book. By being patient, Tom managed to capture this bird having a quality preening session. Here are 4 shots from the sequence, including a rare one of the bird calling. To get the full glory of the detail, click on each image twice.

Clapper Rails are elusive birds of mangrove swamp and marsh, more frequently heard than seen. They tend to lurk around in foliage and are easy to overlook. You may come across one foraging secretively in the mud. Although they can both swim and fly, they prefer to keep both feet on the ground.When running, these rails look endearingly comical.

It almost goes without saying nowadays, but the biggest threat to these rather charming inoffensive birds is habitat loss. That is to say, mankind. Drive the bulldozers through the mangroves and marshland of sub-tropical coastal areas, chuck down a few acres of concrete… and the clappers will very soon become clapped out.

“TO RUN LIKE THE CLAPPERS”. This phrase seems to be fairly recent, probably dating from early in WW2. Some suggest it is a rhyming slam bowdlerisation of ‘run like hell’ with ‘clapper(s)’ standing for ‘bell’, along the lines of the Cockney “I bought a brand new whistle” (whistle and flute = suit). Almost all plausible explanations relate to bells, and some argue that it simply reflects the rapid speed of the clapper of a vigorously rung handbell.

STOP PRESS Uli Nowlan has sent her photo of a Clapper Rail, taken at the ponds north of Treasure Cay – a reminder that there is good birding to be done in that area of North Abaco – the bird action is not confined to South Abaco below MH…

Hitoshi Miho is a diver and photographer who takes amazing photographs of the underground caves he explores. These include some of the cave systems on Abaco, where he has recently accompanied renowned Abaco diver Brian Kakuk of the Bahamas Caves Research Foundation. In due course I hope to produce a page dedicated to the Caves and Blue Holes of Abaco including maps but that’s a project in the mind for now. Meantime, with Hitoshi’s kind permission, here are a few preliminary examples of his fabulous work that showcases the wondrous crystal palaces that lie deep beneath Abaco.

JLM Special makeover – back to Abaco?

metiefly

Constructive feedback is a wonderful inspirer. Esteemed fellow blogger and author of a stunning Bird book, RH (of rollingharbour.com) painstakingly limited his catch rate on my behalf during his last sojourn in the Abaco Marls. Persisting long after his wiser companions abandoned the JLM Special in favour of their tried and tested stalwarts, RH very kindly gathered all the empirical evidence he needed to tell me the following:

These flies don’t work in Abaco! Not even by accident! (These are my own words – RH is far more generous and polite :-))

RH went on to provide constructive insights to help me refine my approach:

“Basically, much too dark for the waters of Abaco, too bushy, no streamer tail, no sparkle.”

My first creative reaction is to take care of the colour tones…

Prototype1 - this albino variant is made by combining arctic fox tail with ginger (yes ginger!) elk hair and white embroidery thread. To give it some colour and fine movement, I used blonde hare fur tips. For the telson, a sliver of red wool .

GRAY ANGELFISH: BAHAMAS REEF FISH (18)

Some time ago I posted about GRAY ANGELFISH Pomocanthus arcuatus. They are the more dowdy cousins of the flashy QUEEN ANGELFISH. They are not without their own beauty, though, and I have collected a few more photos of this species taken by Melinda Riger of Grand Bahama Scuba. I’m always pleased to feature her amazing reef photos, with their vivid colours and clear detail, so I hope you enjoy these. The last one – with the stripes – is a juvenile.

GEE! BEES!! HIVE TALKIN’ ON ABACO

GEE! BEES!! HIVE TALKIN’ ON ABACO

This post concerns the bees of Abaco, with little or no apology for the cultural cross-reference to the dread mid-70’s musical era. If you wish to experience the full horror, scroll straight to the bottom of the page and relive those heady days of Barry, Robin & Maurice…

The bees on Abaco south of Marsh Harbour are mostly wild. The header photo shows the West Indian Woodpecker nest box near the skiff park at Delphi that has become the exclusive residence of bees. They have a profusion of flowers in the Delphi Club gardens to choose from, but it is not practical to keep hives for them. So they are left to do their own thing. Here they were last month, being busy.

During the past year I have found 2 places between Delphi and MH that keep hives. One is PEPPER POT FARMS – click the name to reach their FB page. You can get their honey direct or in MH for $6.75 a pot. I enjoyed their evidence of why bees are called ‘workers’…

5 FUN BEE FACTS

Bees must visit approximately 2 million flowers to make 1 lb. of honey.
Bees have to fly over 55,000 miles to make 1 lb. of honey.
On average a worker bee will make 1/12 teaspoon of honey in her lifetime.
Two tablespoons of honey would fuel a honey bee flying once around the world.
Honey bees will visit between 50-100 flowers during one nectar collection trip.

The other place with hives is ABACO NEEM FARMS, the base for the production of the stock at the Abaco Neem shop on the way into MH from the roundabout . The owner Nick has installed 2 hives which we had a look at when we took up his invitation to bird-watch there. It is something of a birding hotspot, benefitting from pine woods, coppice, fruit trees and open land over a large area.

There was plenty of bee action around the hives on a warm sunny day and plenty of plants for them to feed from. We watched them come and go, the returning bees having filled their trouser pockets with pollen.

There are both cultivated and wild flowers all over the place, with bees feasting on plants and fruit trees of many kinds. I liked the bright flower chosen by this bee.

I’ll be posting more about the birds and plants of the Neem Farm in a while. Meanwhile, here are a couple of links to previous relevant links.

FIVE STARS: BAHAMAS ENDEMIC BIRDS (FOUR FROM ABACO)

The Caribbean Endemic Bird Festival is underway. You can find out more on the CARIBBEAN BIRDS FESTIVALS Facebook page. Abaco is fortunate to be home to 4 of the 5 endemic Bahamas species. The fifth, the beautiful BAHAMA ORIOLE Icterus northropi, was found on both Abaco and Andros until the 1990s, when it sadly became extirpated from Abaco. Now found only on Andros, there are thought to be fewer than 300 Orioles left – a barely sustainable number. The species is unsurprisingly IUCN listed as critically endangered. Here’s a picture of one as a reminder of what Abaco is now missing…

Bahama Oriole

Abaco’s four endemic species are the tiny Bahama Woodstar hummingbird, the Bahama Yellowthroat, the Bahama Warbler (since 2011), and the Bahama Swallow. All are of course permanent breeding residents on Abaco and its outer Cays. None is exclusive to Abaco; all are relatively plentiful. The Woodstar is perhaps the hardest to find, not least because it competes territorially with the Cuban Emerald hummingbird. Even Woodstars can be found easily in some areas – Man-o-War Cay is a good place for them, for example. Here are some striking images of these four endemic bird species taken from the archives for “The Birds of Abaco” published last month.

“The Delphi Club Guide to the Birds of Abaco” was published as limited edition of 500 and has only been for sale for 8 weeks or so exclusively through the Delphi Club. Yesterday, we passed a happy milestone in that short time as the 250th copy was sold. Complimentary copies have also been donated to every school and relevant education department on Abaco to tie in with the excellent policy of teaching children from an early age the value of the natural world around them, the importance of its ecology, and the need for its conservation. The cover bird for the book was easy to choose – it just had to be a male Woodstar in all his glory with his splendid purple ‘gorget’.

WHICH ABACO BIRD HAS A YELLOW BELLY & SUCKS SAP?

April 25, 2014 by Rolling Harbour

WHICH ABACO BIRD HAS A YELLOW BELLY & SUCKS SAP?

You’re ahead of me here, aren’t you? The answer of course is… Sphyrapicus varius. Abaco has two permanently resident woodpecker species, the WEST INDIAN WOODPECKER and the HAIRY WOODPECKER. There is a third, migratory woodpecker species that is a fairly common winter resident, the yellow-bellied sapsucker. Like its woodpecker cousins, the sapsucker drills holes in trees (see below). The dual purpose is to release the sap, which it eats, and to attract insects that it also eats. A two-course meal, if you like. They’ll also eat insects on an undrilled tree, and even ‘hawk’ for them in flight. They balance their diet with fruit and berries.

The distinctive patterns of sapsucker holes may completely encircle the trunk of a tree with almost mathematical precision. This is sometimes described as ‘girdling’ and may have a damaging effect on a tree, sometimes even killing it if the bark is severely harmed. This may require preventive measures in orchards for example, though note that in the US Yellow-bellied Sapsuckers are listed and protected under the Migratory Bird Treaty Act so radical action is prohibited.

YELLOW-BELLIED SAPSUCKER SOUNDS

DRUMMING (Xeno-Canto / Richard Hoyer)

CALL (Xeno-Canto / Jonathon Jogsma)

On Abaco, palms are a favourite tree for the sapsuckers. There are several palms along the Delphi beach, and this year I noted that one coconut palm in particular had seen plenty of sapsucker action, with the drill holes girdling the entire trunk from top to bottom.

In their breeding grounds yellow-bellied sapsuckers excavate a large cavity in a softwood tree as a nest. They mate for life, and often return to the same nest year every year, with the pair sharing nesting duties. I have no idea whether the pair migrate south for the winter together, or whether they agree to take a break from each other. I’d like to think it’s the former…

BIRDS, PLASTIC & CONSERVATION: A CONTROVERSIAL AD…

BIRDS, PLASTIC & CONSERVATION: A CONTROVERSIAL AD…

Rolling Harbour is a broadly neutral territory. We occasionally do ‘opinionated’ round here. We are not afraid to express views. But we try to avoid controversy and in particular, politics in its broadest sense. There have been occasional lapses into outrage – one example was the huge cruise ship taking a shortcut (allegedly, I had better add) that trashed significant areas of irreplaceable coral reef and smeared poisonous anti-fouling paint along the seabed, affecting reef life for decades and… Stop me right there!

The most sensitive area is conservation. Some issues are straightforward; with others the balance of what is right and wrong is more debatable. One particular aspect that can be problematic is in the presentation of information. We are all familiar with charity appeals that cajole with images of happy children or sweet puppies. We also see the ones with horrific images that are uncomfortable or even downright unpleasant to look at. Both can be powerful and valid ways to raise awareness and attract support. Some of the more extreme images used may actually have the effect of repelling people. The same is true with conservation projects. There are ones illustrated with images that make you go ‘ahhhh’ and smile; others are undeniably distressing and will make you wince with uneasiness.

See how you react to this 45 second video from Australia. It is made by Greenpeace – itself a controversial organisation in some eyes – and concerns Coke, plastic and birds. I had no idea what to expect, and it gave me a jolt. It has been the subject of legal action, of alleged censorship and interference from powerful lobbies, and a sizzling amount of anger. It won’t take you long to watch it. Compare how you feel during the first ten seconds with how you feel 30 seconds later…

BIRD SPOTTING ON ABACO? EASY! SPOTTED SANDPIPERS…

BIRD SPOTTING ON ABACO? EASY! SPOTTED SANDPIPERS…

The Spotted Sandpiper Actitis macularia is a common winter resident on Abaco. These pretty shorebirds are only spotted part-time – in the breeding season – when they look like this…

Spotted Sandpiper.Abaco Bahamas.Tom Sheley FV

Spotted Sandpiper (breeding plumage)

Spotted Sandpiper Actitis macularia Wiki

Spotted Sandpiper (breeding plumage)

The species sets a fine example for gender equality – role reversal, even. The female Spotted Sandpipers are the first to arrive in the breeding area, with males following on. Once a female has staked out her nesting territory, she is the one to defend it. A male will then arrive on the scene, and (if approved of) they mate. Once the eggs are laid the male takes on the egg incubating duties and the subsequent chick care once they hatch. While he is occupied with domestic concerns, the female may take the chance to play away from home and produce eggs with other males. Just imagine if humans of either sex behaved like that… Oh. Sometimes they do apparently (sources: The Daily Snooper; Celeb Shocker!)

A BONEFISHING CHALLENGE ON ABACO: THE ‘WHICH?’ REPORT

April 16, 2014 by Rolling Harbour

A BONEFISHING CHALLENGE ON ABACO

In January I posted an article called BONEFISHING ON ABACO: A CHALLENGE IS ACCEPTED. This stemmed from contact online with fisherman and fly tyer Mark Minshull, who kindly tied some flies for me to try on the Marls. In the post I showed pictures of my manky flybox and his immaculate flies. We agreed to see how things turned out while I was on Abaco in March, and that I would report back…

Mark 1 Specimen Bonefish Flies

THE ‘WHICH?’ REPORT ON MARK 1 BONEFISHING FLIES

We set out to test the efficacy of prototype ‘Mark 1’ bonefishing flies in the waters of the Abaco Marls. Our testers came from the US (TC & AH), Northern Ireland (AB), and England (RH). All are proficient fly fishermen with experience of several prime bonefishing destinations between them, except for the Englishman RH who was included to add balance to the trials by adding the element of incompetence. His fly box remained an object of ridicule throughout the tests, until he resorted to using a more carefully chosen small fly box containing his most successful flies, some ‘Delphi Club Approved’ flies and the test flies.

QUALITY All our testers agreed that the Mark 1 flies were beautifully designed and tied. As flies, their quality was rated ‘superb’; ‘bloody good’; and ‘very impressive’. As potential winners for the waters of Abaco, however, there was considerable doubt about the suitability of the pattern for colouring, shape and size.

THE TEST AREA We used the huge area of prime bonefishing territory of the mangrove swamps and sand banks on the west side of Abaco known as the Marls. Our testers were familiar with the waters and all had fished them numerous times. The sea depth, depending on tide, is a few feet at most. The consistency of the bottom is of lightweight, pale coloured mud.

It is usually easier to look out for the shadows of the fish on the light bottom than for the fish themselves, which are often difficult to see in the water. Half-close your eyes and look at this image – the fish almost disappears, but the shadow is clearly visible. It is hard to believe the wonderful colouring of the fish until it is out of the water.

THE TESTS The initial reservations of the testers unfortunately proved justified in the field. The testers all found that the fish tended not to follow the flies at all, and mostly behaved as if they had not seen them, even with the most accurate casts. The few ‘follows’ observed produced refusals of the fly at the end. Disappointingly, no fly was taken by a single fish throughout the trials.

OBSERVATIONS Our testers had some useful comments. Above all, the Mark 1 flies were undoubtedly of excellent quality and design. They simply were not suited to the waters – or the bonefish – of Abaco. TC thought they might work in Belize. It was thought that larger versions might attract permit. Overall, the Mark 1s were so radically different from the tried and tested fly patterns used successfully on Abaco that the 3 competent fishermen soon forsook the experiment and caught fish using more familiar flies. The 4th tester, lacking any finesse, might have fluked a take against the odds , but even he drew a blank.

THE PROFESSIONALS The Guides in each case had been fishing the Marls since they could walk and hold a rod. They each examined the flies, shook their heads and kept their thoughts to themselves. We interpret this as indicating a tendency for the local guides to doubt the effectiveness of the Mark 1 flies.

RH’s ‘Selected Specimen’ Fly Box

RESULTS ANALYSIS The flies above show (front row) the 3 versions of the Mark 1 fly; (middle row) the highly effective Delphi Daddy and Delphi Diva patterns, with one random silver concoction of unknown origin; (back row) ; 2 browny / pale patterns plus a shocking pink one that the guides wisely forbade and, below, 3 roughly matching flies that brought great success even for RH this year (including 12 boated and 5 lost in one day), sourced from renowned tackle specialist E. Bay.

CONCLUSION The flies that catch the bones on Abaco tend to be pale and to have ‘streamer’ tails and / or a fair amount of sparkle. A touch of pink seems to be good. Too much pink, not so. Rubbery legs can be very effective (except in the fisherman after lunch). But lovely lifelike dark shrimp imitations are of no interest to the fish of the Marls.

BLACK-AND-WHITE WARBLERS ON ABACO

April 14, 2014 by Rolling Harbour

The Black-and-White Warbler Mniotilta varia is a fairly common winter resident on Abaco. They are the only birds of the genus Mniotilta (“moss-picker” gr.). Unlike most warblers these birds behave rather like nuthatches, creeping along the trunks and branches of trees grubbing insects out of the bark. Pine trees are ideal for this. I remain rather dim about the 37 species of warbler on Abaco. A lot of them are small and yellow. But as soon as I saw one of these for the first time, I was very relieved. I knew exactly what it was – the bird that has been described as ‘a flying humbug’.

SUMMER WINTER

Finally, this is a great short video of this little bird in action. Even if you only watch the first 30 seconds, you will be enchanted…

THE CONCH QUEST OF ABACO…

April 11, 2014 by Rolling Harbour

THE CONCH QUEST OF ABACO…

Conchs are gastropods. They are food. They are decoration (anyway, the shells are). For some, they are a living. And on Abaco they are everywhere – alive in the waters, and as shells scattered on beaches or piled up outside restaurants. So the quest for conch is an easy one. There are fears of overfishing, however, and an active organisation The Bahamas National Conchservation Campaign exists to protect them. Another similar Bahamas organisation is Community Conch. We found a nice half-buried conch shell at Sandy Point. It was full of sand grains and tiny shells – mini gastropods and bivalves – that took some time to wash out of the spiralling internal structure. Here are some studies of the shell. The damage to the shell above is the place where it has been bashed in to enable removal of the occupant. In order to do so, it is necessary to break the strong vacuum that would prevent extraction if you tried by the conventional route. Effectively the conch anchors itself to its shell and must be cut out. The best way to make the hole is with the spiral tip of another conch. This breaks the suction and enables you to prise out the occupant…
