BAHAMAS REEF FISH (38): SPOTFIN BUTTERFLYFISH


Spotfin Butterflyfish, Bahamas (Melinda Riger / G B Scuba)

BAHAMAS REEF FISH (38): SPOTFIN BUTTERFLYFISH

Butterflyfishes are a large family of mainly colourful small fish somewhat like mini-angelfish. The spotfin butterflyfish (Chaetodon ocellatus) is one of several types of butterflyfish found in the western Atlantic Ocean; and one of half a dozen or so you are likely to see nosing around the coral reefs of the Bahamas.

Spotfin Butterflyfish, Bahamas (Melinda Riger / G B Scuba)

The name ‘spotfin’ derives from the dark spot on the dorsal fin. At the front end, there is a distinctive black vertical stripe that passes right through the eye. Combined with the vivid colouring, predators are in theory confused or warned off.  The spotfin’s superpower (on a modest scale) is that at night, a change of appearance occurs in adults. The dark patch on the dorsal fin increases in size, and dark bands appear on the body. This seems to be in order to provide further protection during the darker hours.

Spotfin Butterflyfish, Bahamas (Melinda Riger / G B Scuba)

The spotfin above has an isopod attached to it, a type of crustacean with a segmented body. Primitive fossils of these creatures have been dated back some 3m years. Want to know want this one is up to? These things “are mostly external parasites of fish or crustaceans and feed on blood, having piercing and sucking mouthparts and clawed limbs adapted for clinging onto their hosts”.

Soldierfish photobombs a spotfin. Or maybe it’s vice versa?Parasitic species are mostly external parasites of fish or crustaceans and feed on blood. The larvae of the Gnathiidae family and adult cymothoidids have piercing and sucking mouthparts and clawed limbs adapted for clinging onto their hosts.

Reading about this particular species of  butterfly fish, I discovered that the spotfin “is very common and very hard to maintain in a tank” –  as if the two facts are somehow connected. So might they be coarse or vulgar, and thus unsuitable companions for better bred and perhaps sensitive aquarium fish? As it turns out, it may be because they are vulnerable to predation, and so can coexist only with peaceable tank friends. 

Spotfins are perfectly happy swimming upside down; and their party trick apparently is to rise to the surface and squirt a jet of water in the air. Sadly, I couldn’t come up with a photo of this…

RUDDY TURNSTONES ON ABACO: BEACH NOSHING


Ruddy Turnstones, Delphi Beach Abaco Bahamas (Keith Salvesen)

RUDDY TURNSTONES ON ABACO: BEACH NOSHING

Some birds are named for the sounds they make (bobwhite, chuck-will’s-widow, pewee, killdeer). Some are named for their appearance (yellow-rumped warbler, painted bunting). And some are named for what they do (shearwater, sapsucker – but definitely NOT killdeer). The ruddy turnstone Arenaria interpres is in the last two of these categories: it looks ruddy and it literally turns stones to get at the goodies underneath.

Ruddy Turnstones, Delphi Beach Abaco Bahamas (Keith Salvesen)

And they don’t just turn stones to look for food. Someone with a lot of patience has defined 6 specific methods by which a turnstone forages for food:

  • Turning stones by flicking them with its beak
  • Digging using its beak to flick away sand or earth (see video below)
  • Routing around in piles of seaweed to expose food under it
  • Surface pecking with short, shallow pecks for food just below the surface
  • Probing by simply sticking its beak deep into soft sand or ground
  • Hammer-probing to crack open a shell and get at the occupant

Ruddy Turnstones, Delphi Beach Abaco Bahamas (Keith Salvesen)

In these photos taken on a rather gloomy day on the Delphi beach, a combination of mainly digging and routing is going on. Note the sandy beak of the RUTU below, right up to the hilt.

Ruddy Turnstones, Delphi Beach Abaco Bahamas (Keith Salvesen)Ruddy Turnstones, Delphi Beach Abaco Bahamas (Keith Salvesen)

This short video shows how effective the RUTU method is. It was fascinating to watch the team work their way through and around the piles of weed on the beach, flicking sand vigorously in their quest for sandflies or whatever. Watch the sand fly! Pity it wasn’t a sunny day – the photos might have looked a bit more cheerful…

SEA GLASS TREASURES & TWO ISLAND CHICKS…


Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)

SEA GLASS TREASURES & TWO ISLAND CHICKS…

It’s time to shine the Rolling Harbour spotlight on sea glass, a neglected (by me) topic recently . Everyone loves it (don’t they?), and there’s always a bit of excitement in finding a pretty piece of cloudy glass gleaming in the sand on the beach. Just look at that colour. Might it be rare? How old could it be? Should I pick it up or leave it for someone else to enjoy? 

Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)

Collecting sea glass is one of the pleasures of a walk on the beach. Or maybe it’s the motivation for the walk. For some, it is an opportunity to turn what the sea throws onto the beach into something decorative. Abaco is home to some excellent jewellery** makers who specialise in using locally found materials to make beautiful things. These sometimes incorporate a mix of sea glass, pebbles, and small shells.

Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)

In Hopetown on Elbow Cay, Hilary Thompson and Erika Feszt Russell do just that. Trading under the name ‘Two Island Chicks’, they use sea glass in many of their creations, some examples of which are displayed here. As you’ll see, they also apply their creativity to showing their jewellery attractively. 

Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)

The collected glass has to be sorted into the various colours. Most are quite common (white, green, brown), some are uncommon (eg cobalt blue), and just a few that are very rare – and possibly valuable (red, orange) – see charts below.

The charts below give a general overview of the comparative rarity of various sea glass colours, their sources, and the chances of making a rare find. Of course, these are mainstream colours; there are many other in-between hues and shades.

EYES ON STALKS: CONCH WATCH ON ABACO

This is not so much about you looking at, and admiring (without salivating too much, I trust) conchs in their natural element. More about them watching you watching them – and focusing on their rather remarkable stalk-based eyes. Take a look at these examples of the ‘watcher in the shallows‘ (to misquote a well-known book title).

Conch and their eyes, Bahamas (Melinda Riger)Conch and their eyes, Bahamas (Melinda Riger)

HALF A DOZEN CONCH EYE FACTS TO PONDER

  • The eyestalks are attached to an extendable ‘snout’
  • The two eyestalks (ommatophores) are retractable within the shell
  • Their purpose is to provide a wider field of vision around the shell
  • The eyes at the tip of each eyestalk have ‘proper’ lenses, pupils and irises 
  • Amazingly, amputated eyes normally regenerate completely
  • The small projection below the eye is a ‘sensory tentacle’ or feeler

DOLPHINS DISPORTING IN THE BAHAMAS


Atlantic Spotted Dolphin, Bahamas (BMMRO)

DOLPHINS DISPORTING IN THE BAHAMAS

‘Disporting’. Not a word I’ve used very often. Or possibly ever. It looks a bit like ‘unsporting’, which is emphatically what dolphins are not. Basically, it just describes what dolphins are doing when you see them on the surface: amusing themselves, frolicking around in the waves, and simply enjoying themselves.Bottlenose Dolphin, Bahamas (BMMRO)

True, they are probably keeping an eye out for food… But when you have a group sociably following alongside the boat your are in, moving in front, dropping behind, diving under, and generally playing around, it’s quite hard to believe that these are completely wild creatures. They seem to be performing just for you, simply because they want to. You don’t even have to throw fish at them to earn this free display.

Atlantic Spotted Dolphin, Bahamas (BMMRO)Atlantic Spotted Dolphin, Bahamas (BMMRO) Atlantic Spotted Dolphin, Bahamas (BMMRO)

As is well-known, the BAHAMAS MARINE MAMMAL RESEARCH ORGANISATION (BMMRO) is the custodian for the welfare of these beautiful creatures for the entire Bahamas. However, being based on Abaco and carrying out the majority of the research from the HQ at Sandy Point means that many of the great images that get taken are from Abaco waters. Indeed some are taken within swimming distance (not mine) of the shore.  Bottlenose Dolphin, Bahamas (BMMRO)Bottlenose Dolphin, Bahamas (BMMRO)Bottlenose Dolphin, Bahamas (BMMRO)Bottlenose Dolphin, Bahamas (BMMRO)

The photographs featured here were taken during the last few weeks. Some are of the familiar bottlenose dolphins. The others – with speckled undersides clearly visible in the header image & below – are of Atlantic spotted dolphins. There’s even one of my own taken from the research vessel. Atlantic Spotted Dolphin, Abaco Bahamas (Keith Salvesen)Atlantic Spotted Dolphin, Bahamas (BMMRO)

For the researchers, the most important part of an individual dolphin is its dorsal fin. Unique patterns of cuts and scars mean that each dolphin sighted can be logged and their profiles built up. Some have been found in the same area for many years. They are not usually given jocular names – ‘Davy Jones’, ‘Finny Phil’ or whatever. The first time we went out on the research vessel we were slightly surprised by the practical, scientific calls during a sighting of a dolphin group: “there’s B4 again” and “over there – D5 is back”. All said fondly however – many of the dolphins are old friends.

This dolphin has a notable notch on the dorsal fin with a nick below, & a scar line – with a prominent white scar on the lower front edge Bottlenose Dolphin, Bahamas - Dorsal Fin Damage (BMMRO)

CUBAN EMERALDS ON ABACO: JEWELS BEYOND PRICE

Well I don’t want to overstate it, but there cannot be anyone on the planet who has anything but love for hummingbirds. There’s no existing word for ‘fear of hummingbirds’ – ‘colibriphobia‘ is not a ‘thing’. There’s fear of almost everything else, from grass to clouds to plastic bags**… but, surely, not hummers. Here are a few to enjoy.

The females have a wonderful metallic sheen that makes them shimmer in the sunshine. Males are darker: a gorgeous, handsome green. The Emeralds are one of those bird species where it is hard to decide between the sexes which is the more beautiful…

ROCK BEAUTY: BAHAMAS REEF FISH (37)


Rock Beauty, Bahamas (Melinda Riger / Grand Bahama Scuba)

 ROCK BEAUTY: BAHAMAS REEF FISH (37)

The Rock Beauty Holacanthus tricolor is a small species of Angelfish. Seen swimming around the reefs they are unmistakeable, not least because of their bright yellow hi-viz jackets, remarkable blue eyeliner and blue-black lippy. They featured near the start of this series HERE, and a recent online search (for something else completely, as is often the way) reminded me to give them another swim round Rolling Harbour.

Rock Beauty, Bahamas (Melinda Riger / Grand Bahama Scuba)

In addition to the hi-viz-and-eyeliner combo, the Beauty above has chosen a fetchingly cheeky pair of matching ISOPODS (crustacean parasites) to adorn its face –  possibly the piscine equivalent of a tat…

Rock Beauty, Bahamas (Melinda Riger / Grand Bahama Scuba)

Rock Beauties look like prime candidates for anyone’s aquarium, but their dietary requirements and tendency for aggression make them unsuitable. They are highly specialised feeders, needing marine sponge in their daily diet. They are also prone to chase their tank-mates and nip them. On balance, they look more fetching nosing about the coral anyway.

WHAT DO JUVENILES LOOK LIKE?

Juvenile rock beauties are cute mini-versions of the adults, only more yellow (including the lips). In some development stages, they have a smart blue circle in the middle of the dark patch on their sides (bottom image).

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.

ANTILLEAN NIGHTHAWKS REVISITED


Antillean Nighthawk, Abaco (Sandy Walker)

ANTILLEAN NIGHTHAWKS REVISITED

In 2014 I wrote about finding myself – with others on a birding expedition – in the midst of dozens of nighthawks as they swooped and dived (dove?) while hawking for flies. “The birds were quite unperturbed by our presence, and from time to time would zoom past within inches of our heads, making a swooshing noise as they did so”. You can find the post at FAST FOOD ON THE WING.

Antillean Nighthawk, Abaco (Stephen Connett)

Nighthawks catch flying insects on the wing, and mostly forage at dawn and dusk – or (more romantically) at night in a full moon. 

Antillean Nighthawk (Stephen Connett)

Besides aerial feeding displays, nighthawks may also be seen on the ground, where they nest. I say ‘nest’, but actually they hardy bother to make an actual nest, but just lay their eggs on bare ground. And, more riskily, this may well be out in the open rather than concealed. The eggs – usually 2 – hatch after 3 weeks or so, and after another 3 weeks the chicks fledge.

  Antillean Nighthawk Egg (Stephen Connett) Antillean Nighthawk Egg (Stephen Connett)

Fortunately their colouring enables them to blend in with the landscape – a good example of bird camouflage in natural surroundings.

The photos above are from Sandy Walker (header), Stephen Connett – to whom special thanks for use permission for his great nighthawk and egg images – and the last one by bird legend and author of the locus classicus The Birds of the Bahamas (without which no trip to the Bahamas is complete), Bruce Hallett.

Antillean Nighthawk Chordeiles gundlachii, is a species of nightjar. These birds have local names such as ‘killa-ka-dick’, ‘pi-di-mi-dix’, ‘pity-pat-pit’, or variations on the theme, presumably onomatopoeic. Pikadik-(dik) will do for me. See what you reckon from these recordings (excuse the thick-billed vireo – I think – in the background):

Andrew Spencer / Xeno-Canto

ODD FACT

I have read in several sources that no one knows where these migratory birds spend winter; or else that winter season data is ‘scarce’. So no sensible range maps exist, for example. If you read this, and have antillean nighthawks (as opposed to common nighthawks) all round you in winter, please tell someone – you may hold the key to an ornithological mystery…

As so often, the Bahamas Philatelic Bureau leads the way with natural history stamps. The 15c Antillean Nighthawk above featured in a 2001 bird set. You can see dozens more very excellent Bahamas bird, butterfly, fish, flower and other wildlife stamps HERE.

IN A CLASS OF ITS OWN: THE LIMPKIN


Limpkin wading (Michael Vaughn)

IN A CLASS OF ITS OWN: THE LIMPKIN

The Limpkin has a special status: it is in a Class of its own. Actually, it is in a Family of its own in terms of strict Linnean classification. It is in the Class ‘bird’ and the Order ‘crane and rail’. But there is no other creature in its Family or Genus. So it’s on its own, bird-wise. None like it anywhere. It is ‘monotypic’. 

Limpkin (Michael Vaughn)

These snail eaters are said to be named for their somewhat lame walking method on their long legs. Their long downcurved bills are shaped to act rather like tweezers when feeding on snails. I’ve never managed to get very close to one – they seem to be quite secretive. But boy, can you hear them when they decide to go for it. If you ever hear this sound – quite possibly at night – now you’ll know what creature is making it…

Jerome Fischer / Xeno-Canto

Limpkin wading (Michael Vaughn)

TEN LIMPID LIMPKIN FACTS TO ENTHRAL YOUR FRIENDS

  • The Limpkin has its own ‘monotypic’ family – a one-off species of bird
  • They eat snails and molluscs (also insects, worms & frogs), using their beaks to snatch them
  • They may leave piles of discarded shells in their favourite feeding sites
  • The birds are ungainly and awkward: ‘limpkin’ probably derives from their limping gait
  • Males and females have the same plumage (males being slightly larger)
  • The beak acts like tweezers – slightly open and closing at the tip – for tweaking snails etc
  • Territory is defended aggressively, with ‘ritualized charging and wing-flapping’ at intruders
  • Sex lives: they are monogamous; or polyandrous (a male and more than one female. Tsk.)
  • They use ‘courtship feeding’ – males will catch and shell a snail and then feed it to a female
  • They are also known as the ‘Crying Bird’ for their bizarre shrieking call, as used in films**

** Specifically, as a generic jungle noise in Tarzan films; and apparently for the hippogriff in one of the Harry Potter films.

BAHAMAS REEF FISH (36): REEF BUTTERFLYFISH


Reef Butterflyfish, Bahamas - Melinda Riger / Grand Bahama Scuba

 BAHAMAS REEF FISH (36): REEF BUTTERFLYFISH

Butterflyfishes come in several varieties in Bahamian waters; and there are more than 120 species worldwide. Not so long ago I wrote about the LONGSNOUT variety, also known as the “Butterbun”. Now it’s time to take a look at the Reef Butterfyfish.

Reef Butterflyfish, Bahamas - Melinda Riger / Grand Bahama Scuba

In some ways butterflyfishes resemble small angelfishes – adult Reefs are just a few inches long. As the name suggests, these are creatures of the reefs, and of shallow waters. As one might expect, these colourful fish are popular for aquariums (or, strictly I suppose, aquaria). 

Reef Butterflyfish, Bahamas - Melinda Riger / Grand Bahama Scuba

Butterflyfishes have interesting spawning patterns. They release large numbers of buoyant eggs into the water. These become mixed in with plankton and suchlike, and float where the tides take them until they hatch. Then, most unusually, they go through a larval stage when they are covered by bony material, which they lose as they mature. This is known as an ‘armoured’ stage, which I can only assume is to provide protection to the tiny fry – perhaps by making them crunchy and unappetising. I’ve been trying to find a usable illustrative drawing, without success so far.

Reef Butterflyfish, Bahamas - Melinda Riger / Grand Bahama Scuba

OPTIONAL MUSICAL DIGRESSION

In some parts of the world the butterflyfish is called a BORBOLETTA, which is Portugese for ‘butterfly’. It is also the title of Santana’s criminally underrated sixth album (1974). For sure it’s no 1st, Abraxas, 3rd or Caravanserai… but if you can tolerate the man’s move to ‘jazz-funk-fusion’ – maybe John McLaughlin had a hand in that – there is much to enjoy. There’s less searing guitar and there’s some strange ‘soundscape’ stuff that’s maybe not to everyone’s taste. But still – it stand up pretty well in comparison with some of the later Carlos creations where a certain tiresomeness began to creep in and some tracks are (IMVHO) not really listenable-to. Anyway, the recently released (2016) Santana IV is a welcome return to the good old days, and the good old team.

Here’s ‘Promise of a Fisherman’ – 8 minutes of  Santana, from which you can judge the direction he’s taken by Album 6…

HOOPOES: THE TARGET FOR THE WEEK (NOT ON ABACO!)

HOOPOES: THE TARGET FOR THE WEEK (NOT ON ABACO!)

From time to time, wildlife that is completely alien to Abaco, the Bahamas, or even the Americas will slip under the radar and find a place hereabouts. I’m hoping to find one such during the next few days. It is Upupa epops: the Eurasian hoopoe. This wonderful creature is a bird of the warmer areas of Europe and Asia (orange on the map below), and widespread (non-breeding) in areas further south including Africa.

Very occasionally they are found in the south of England, but we are travelling to the Balearics and the hoopoe is merely incidental to the expedition. I’ve seen them in France, Italy, and on Mallorca… and we are in with a good chance of finding one this coming week. So I’d better to remember to have more than iPhone with me…

The hoopoe’s most distinctive feature is its extraordinary erectile crest, which creates an impressive fan on top of its head. Then there’s attractive colour scheme. And that long, down-curved, insect-pecking beak. And that unmistakeable call, an onomatopoeic name that really fits the species (cf Whip Poor Will):

There is a very real chance of finding and photographing this gorgeous bird, but I appreciate that it’s probably not of sufficient interest Abaco-wise to justify a second post so I’ll probably just put an image on Insta and FB. If any are good enough…

SCOOP (2): AMAZING BLACK SKIMMERS & CHICKS

SCOOP (2): AMAZING BLACK SKIMMERS & CHICKS

Last year I posted about an avian scoop, when black skimmers (Rynchops niger) were actually photographed on Abaco. These wonderful birds are classified WR 4 for Abaco, which means uncommon winter residents (ie roughly September until April). Now I look into it further on the indispensable eBird, there are actually quite a few reported sightings most years on Abaco – especially on the Cays. Furthermore the sightings cover most months except midsummer. So maybe they aren’t so rare after all. But I couldn’t track down any workable Abaco skimmer photographs until Charmaine Albury managed to take a few last Autumn, which led to the gift post title SCOOP. Because that is just how they feed.

Danny Sauvageau is a dedicated birder in Florida, and a brilliant photographer with it. From time to time I feature his work when his camera skills cover a species found on Abaco but for which Abaco images are scarce (or non-existent). All these photographs were recently taken in Pinellas County, Fl., and I’m really grateful to Danny for permission for occasional use of his exceptional photos.

At the moment, the breeding season is well under way, with the hungry chicks being fed as fast as they can swallow. And this is how that looks, thanks to Danny and his immense talent.

And finally… I’d be really pleased to hear about any Abaco skimmer sightings (and I’ll keep an eye on eBird). Bonus points and a theoretical Kalik for photographs!

RED-LEGGED THRUSHES: MAKING EYE-CONTACT ON ABACO

RED-LEGGED THRUSHES: MAKING EYE-CONTACT ON ABACO

I see it is ‘literally’** years since I last wrote about these lovely, accessible birds, the only permanent resident breeding thrush species on Abaco (out of 8). The post – OL’ RED-EYES IS BACK – featured mainly my own photos, plus one by Mrs RH. With a whole lot of more recent photos, it’s time to revisit these cheery birds. I promised something brighter after two rather sombre shearwater die-off posts – (incidentally, a far wider problem than just in the Bahamas, including NC & Cape May). Here it is.

Many of the birds shown here were photographed in or around the grounds of Delphi. More recently, they have to an extent been displaced by red-winged blackbirds which are of course very fine birds but in large numbers sound (may I say this? Is this just me?) quite irritating after a while. Whereas the thrush of course has a sweet and melodious song, like this (my own recording – turn up the vol):

As I may have mentioned before (impatient reader: ‘yes, yes, you did’), the eyes of the RLT are at least as prominent a feature as their legs. Lots of birds have red legs. Very few have such remarkable bright, fiery eye-rings, even in a youngster.

** This means it really is literally years (4), not in the modern modified sense of ‘not actually literally’, as  in “I am literally dying of hunger”. Unless you are exceptionally unfortunate, while you have the breath to say you are, you are literally not doing so…

FUN FACT

There is quite literally no song since 1950 with the word ‘thrush’ in the title. Hard to fathom why… One or two songs have a thrush buried away in the lyrics somewhere. Blackbirds have done rather better in this respect…

SHEARWATER DIE-OFF ON ABACO: UPDATE

SHEARWATER DIE-OFF ON ABACO: UPDATE

A week ago I posted about the reports of dead and dying Audubon’s shearwaters being washed up on various beaches on the Abaco mainland in and around Cherokee Sound and down to Bahama Palm Shores. I included some advice about how to deal with these poor birds. You can find the post HERE.

The very next day, reports began to emerge of another species, great shearwaters, being found dead or in a distressed state just off-shore or washed up on beaches. Reports were fewer, but covered a wider area, including a bird in a very poor condition at Delphi. Great shearwaters were the ones involved in the die-back event 2 years ago.

Keith Kemp, who made one of the earlier Audubon shearwater reports, found a young great shearwater in trouble in the sea while he was out in a kayak off Cherokee Point. He rescued it and took all sensible precautions to nourish it and make it comfortable but sadly it did not last the night. He has frozen the bird as a specimen in case analysis will help to explain this die-off event.

As I wrote before, these birds of the open ocean may become weakened and exhausted if fishing conditions become adverse. They will drift weakly with the tide, dying at sea or washing up in a very poor state in the tideline or on beaches.  Their prospects of survival if rescued is sadly very slim – I have not yet heard of a success, though I would love to…

Thankfully, during the past week, reports have gradually diminished. I’ve not seen one for a couple of days. With any luck, the current die-off is now over and will not be repeated for several years. However, another one will certainly happen, I’m afraid – maybe in 5 to 10 years time, the usual gap. Twice in two years has made for very bleak, distressing news.

A more cheerful post will be next, I promise. Meanwhile, any further reports or comments would be welcome.

REDSPOTTED HAWKFISH: BAHAMAS REEF FISH (35)


Redspotted Hawkfish, Bahamas (Melinda Riger)

REDSPOTTED HAWKFISH: BAHAMAS REEF FISH (35)

The redspotted hawkfish (Amblycirrhitus pinos) is one of a number of species of hawkfishes found worldwide. This one is found on the sub-tropical and tropical reefs of the Western Atlantic, and is therefore a fish you might see when out snorkelling or (more likely) scuba-ing in the Bahamas. These are small creatures – adults are unlikely to exceed 4 inches in length.

Redspotted Hawkfish, Bahamas (Melinda Riger)

There’s not a whole lot else to report about them. They have no medicinal superpowers, for example, nor wickedly toxic spines. A quick scroll through the highways and byways of the interweb reveals that redspotted hawkfish are considered (rightly, I think) to be attractive, tend to be shy, enjoy perching on coral ledges, and are generally benign, except to smaller fishes to which they may show aggression or – worse – an appetite. 

Redspotted Hawkfish, Bahamas (Melinda Riger)

As you might predict, these pretty little fish are popular in the aquarium trade, where on any view they should be kept safe from predators. But maybe captivity is a little limited in opportunities for travel and exploration. They can be bought for (I just checked) $29.99. Or else left alone on a reef to take their chances.
