SHARK ATTACKS – ABACO, BAHAMAS & BEYOND

Over the last couple of weeks or so I have been getting a lot of hits for Shark Attack information. There have been 2 or 3 recent incidents including a tragic (and very rare) death in Maine, which may well account for this. The Shark Attack details I have accumulated and posted over the years are buried in an historical sub-sub-page, so to make things easier I have rechecked and updated the latest data resources and their links, and put them in a mainstream post. This is it.

DATABASE UPDATE 2020

INTERNATIONAL SHARK ATTACK FILE

PRIMARY RESOURCE

This resource is the portal to a mass of current, recent, and historical data, presented with authority and clarity. It provides undoubtedly the most comprehensive and accessible global shark-incident data of all.

Last year I included informative screen-shots taken from this site. For now I am confining the information to the most useful direct links. More work for the reader, perhaps, but also a better chance to explore and understand the hows, whens and wherefores of shark-related incidents – and how best to avoid the situation in the first place.

The 2019 worldwide total of 64 confirmed unprovoked cases were lower than the most recent five-year (2014-2018) average of 82 incidents annually. There were five fatal attacks this year, two of which were confirmed to be unprovoked. This number is in line with the annual global average of four fatalities per year

For anyone thinking of entering waters where sharks live – eg scuba divers, spear-fishers, swimmers, boaters – with relatively little experience or knowledge, these links will be incredibly useful. Local knowledge is well worth having as well. A young friend of ours, an intern on Abaco, was warned against spearfishing at a particular location: “Fish there, you’ll get ate”. He did. He very nearly was.

“Humans are not on the menu of sharks. Sharks bite humans out of curiosity or to defend themselves”

The SRI produces a  downloadable Global Shark Attack File that provides:

  • A downloadable incident log by country
  • A downloadable incident log chronologically
  • A world map of encounters categorized by provoked vs. unprovoked, incidents involving boats, air & sea disasters and questionable incidents

A FINAL THOUGHT

 

BLACK-FACED GRASSQUITS ON ABACO, BAHAMAS

BLACK-FACED GRASSQUITS ON ABACO, BAHAMAS

A while back, Black-faced Grassquits Tiaris bicolor were honoured by the American Ornithological Union with a classification change from emberizid to tanager. For the reasons that follow, the species regarded this both as scientific promotion and as merited status elevation. I invited an authoritative Spokesquit to explain why.

*******************

Hi, human friends, I’m a black-faced grassquit  and I have a couple of observations to make on behalf of BFGs, if I may. First, we seem to be universally described by you as ‘common’, whereas we are actually quite refined in our behaviour. Secondly, the words most used to portray us are ‘dull’ and ‘drab’. And ‘stubby’. Well, excuse me… I – we – ask you to give us a second look. Maybe check out these images for a start.

black-faced-grassquit-adult-male-eating-berry-abaco-bahamas-tom-sheleyblack-faced-grassquit-foraging-berry-2-abaco-bahamas-tom-sheley

Unsurprisingly we were very excited when the perceptive classifications committee of the American Ornithological Union gave us an upgrade. That’s the way we saw it anyway. For many years we were classified under the heading emberizidae. 

Black-faced Grassquit male, Abaco (Bruce Hallett)Black-faced Grassquit, Abaco (Tom Reed)

We kept company with some buddies like the handsome Greater Antillean Bullfinches, but also with a lot of New World sparrows, with whom we (frankly) never felt entirely comfortable. Annoyingly chirpy, for a start.

Black-faced Grassquit - Treasure Cay, Abaco (Becky Marvil)Black-faced Grassquit male, Abaco (Peter Mantle)

And so we officially became a type of tanager. They even reckon (rather late in the day, in my view) that we are closely related to Darwin’s finches. So, we are “common”, huh? Now we get to be with other birds that are dome-nesters like us. And how about this – we’ll be in the same list as some really cool birds…

Black-faced Grassquit male, Abaco (Gerlinde Taurer)

How’s this for a colourful gang to be joining: scarlet tanager, summer tanager, rose-breasted grosbeak, indigo bunting, painted bunting – these are our new cousins. BFGs “dull” and “drab”? I don’t think so.

6 UNDULL FACTS ABOUT BFGS

  • Make grassy dome-nests (like Bananaquits) and line them with soft grasses
  • Both sexes build the nest together
  • Both share egg-sitting duties and later chick-feeding & maintenance
  • Though quite gregarious by day, for some reason they tend to roost alone
  • They have a short ‘display’ flight with vibrating wings and a strange buzzing call
  • Otherwise, their flight is ‘weak, bouncy & fluttering’ (Whatbird assessment)

ROLLING HARBOUR? TROLLING HARBOUR!

My troll friend is back! It’s been quite a long time since the last outbreak – congratulations on your growing self-control – but it’s good to know you still have it in you. In a way I consider your dogged trawls through my posts awarding coveted ‘One Star’ (= ‘Very Poor’) reviews, something of a plus. Your indiscriminate and equally low opinion of sequential blocks of posts suggests that you don’t actually read them, so I like to speculate what draws you here. You have the option of never visiting at all, of course, but that may not have occurred to you. Possibly you hate wildlife and / or conservation issues? Or have a phobia about nice photos. Or a lack of empathy for birds. Maybe you hold strong views that you feel are totally valid yet differ from the ones you perceive hereabouts. Possibly you need to see a counsellor?

Black-necked Stilt, Abaco, Bahamas (Alex Hughes)

You doubtless will be pleased to see this post (and keen to award it a single star) expecting me to mind your somewhat negative and persistent attentions. Presumably in some weird way you hope that you have got to me. I’ve been doing this for nearly 10 years and I can assure you not. I could in fact have removed my star ratings at any time, but then I’d miss your badges of honour and you’d miss your fun. If I may make a personal comment, though,  right now the least important thing in the world you could be doing is to troll a wildlife blog. When you have a tranquil moment, would you like to try to find something better to do with your time? Maybe something positive for someone else?

‘A SADNESS OF SHEARWATERS’ ON ABACO: DIE-OFF 2020


Audobon's_Shearwater - Dominic Sherony wiki

‘A SADNESS OF SHEARWATERS’ ON ABACO

If you are walking your favourite beach on Abaco right now, it’s quite possible you may see – or may already have seen – a very poorly seabird. Or one that is dead, I’m afraid. Or you may have read about this online. These poor birds may be (a) Audubon’s Shearwaters (also known as Dusky Petrels), which are the only permanent resident shearwater species on Abaco; (b) Cory’s, Great or Sooty, which are transients; (c) Manx, which is a rare ‘off-course’ vagrant.

JUNE 2020

At the moment there are plenty of posts and threads on social media about the current die-off. People are naturally upset and concerned, and want to know the cause of the phenomenon. I am recasting a post from last year to explain why this happens.

Exhausted shearwater beached on AbacoAudubons Shearwater Abaco Bahamas (Sharon Elliott)

Each sad bird is part of a tragic and recurrent phenomenon, a so-called die-off event. It almost always happens in June. The pattern is much the same each time, though the mix of shearwater species that succumb may vary. I first became aware of this problem in June 2015 and wrote about it then. That bleak time lasted for about a week, and many reports came in from mainland Abaco and the cays, stretching from Green Turtle Cay right down to Crossing Rocks.

audubons-shearwater-abaco-keith-kemp

There was thankfully no such problem in 2016, but in 2017 – also in June – there was another die-back event involving a large number of Audubon’s shearwaters (Puffinus lherminieri) appearing in the tideline and on beaches. Many were already dead. Some were still alive, but in a very poor state. Their prospects for survival would have been very low. A few birds were captured and cared for, but even then the chances of recovery were not good.

Shearwater die-off 2020 Abaco Bahamas (Melissa Maura)

Two years on, in 2019, the melancholy cycle repeated itself. Melissa Maura, well-known as an expert in the care and recovery of creatures of all kinds, posted an alert and some sound advice:

A heads-up to all Island folk that it appears to be a summer when exhausted Shearwaters (pelagic seabirds) are washing up on our beaches in Eleuthera and Abaco. I have had two calls in 24 hours. Should you find one, understand that it will be in a severe state of exhaustion and stress and that excessive handling will kill it. Please put in a safe pen on a sandy surface, with shallow pan of fresh water and try locate either fresh fish (important) or squid from a bait shop. This may have to be administered by gently opening the beak and inserting one inch long piece of fish every couple of hours until stable. Ideally they need tube feeding, but very few folk can do this. Please contact me on private message if you find any…

WHY DOES THIS SHEARWATER DIE-OFF HAPPEN?
This is a periodic phenomenon that looked to be settling into a 2-year cycle in the Northern Bahamas (Eleuthera is also affected). This year’s die-off makes it 2 years running, an obvious great concern. The cause is a combination of factors, very likely stemming from prevailing mid-summer climate conditions and/or the effect of climate change. This can lead to a shortage of food far out in the ocean where the birds spend their days. This in turn leads to weakness and exhaustion as the birds fly increasing distances to try to find food. The birds may then land (or fall) in the sea, to be washed ashore in a very bad state, or more often dead. In 2017, well-known bird expert Woody Bracey noted a correlation between poor Summer fishing conditions out to sea, and an unusual absence of the frigatebirds that are a sure sign of a healthy fish population.

Shearwater die-off Abaco Bahamas (Rhona Pearce))
ARE PLASTICS A CONTRIBUTORY FACTOR?
As we must all accept by now, most if not all these birds will unavoidably have ingested some of our discarded plastic.  However, that in itself would not explain the simultaneous deaths of many birds of one type in a specific area, at exactly the same time of year, and for a few days only. 
Audubon's Shearwater (Neotropical Birds / Cornell / Brian Sullivan)
WHAT ELSE CAN BE DONE?
The dead birds on the shoreline will be quickly removed by the turkey vultures. If you do find one, you might want to bury it. The prognosis for sick birds is not good. They may have been carried a long way from open sea and they will be exhausted and starved. Those that are strong enough may recover naturally; but most will sadly die, being too weak and emaciated to survive. A few lucky birds will be found in a reasonable state, and be able to be nursed back to health.

PRACTICAL ADVICE
(1) move the bird gently into the shade if in the sun
(2) provide clean water in a shallow dish
(3) offer finely chopped fish BUT no bread (it’s very bad for birds)
(4) if this seems to be working, then carry on until the bird is strong enough to fly (this may be quite a commitment)
(5) do not reproach yourself if a bird you try to help dies. Many will be in such bad shape by the time they are washed up that they are unlikely to survive whatever steps you take
(6) remember that this a part – a sad part – of the life-cycle of these birds, and (as with other species), a degree of attrition is an inevitable aspect of natural life

WORLD OCEANS DAY: WHAT YOUR DESCENDANTS MAY MISS

Even the most optimistic lovers of unmolested wildlife, unpolluted oceans, un-degraded habitats, unextinguished species and understanding humans will be beginning to lose heart. Even as reports increase of resurgent wildlife during these Covid months, so it is gradually becoming clear that once humans are unlocked again, the only way will be down.

Here are just a few magnificent marine mammals to admire. All were photographed from the BMMRO research vessel in Abaco or adjacent waters. They are protected, recorded, researched, and watched over in their natural element – some individuals for more than a decade. 

Pantropical spotted dolphinsPan-tropical spotted dolphins, Abaco, Bahamas (Charlotte Dunn / BMMRO)

Today we contemplate our oceans at a time when the human species is having to confront a sudden and indiscriminate destructive force. Maybe the impact will lead to a recalibration of the ways we treat other species and their environment. We have contaminated the world’s oceans, perhaps irreparably, in a single generation. We could start by committing our support to those that tackle the plastic saturation, oil / chemical pollution, acoustic bombardment, ‘ghost gear’, and all the other unwelcome attritional activities we are responsible for. We could continue by supporting those that monitor and protect all the marine creatures struggling in a polluted environment that, in natural law, should be theirs.

Below is a male Blainville’s beaked whale, with its remarkable barnacled tusks that protrude upwards from its lower jaw. This is a specialist research species in the Bahamas. Below that is a short video of these whales that I took from the BMMRO research vessel. Turn up the volume – you will clearly hear them breathing as they slowly pass by (and others in the group, under) the boat. Note that land is clearly visible. These whales can sometimes be found just beyond the shallow turquoise waters, where the sea deepens as the depth drops down to an underwater canyon.

ENDANGERED SPECIES, ABACO (3): NASSAU GROUPER


Nassau Grouper (Melinda Riger / G B Scuba)

ENDANGERED SPECIES, ABACO (3): NASSAU GROUPER

The Nassau grouper Epinephelus striatus is one of a number of grouper species found in Bahamian waters. Of these, only the Nassau grouper is on the IUCN Red List, as Critically Endangered. When I last wrote about them they were in the lesser category ‘Threatened’.

Nassau Grouper (Melinda Riger / G B Scuba

In order to sustain a viable population, it is vital to maintain numbers and preferably to increase them year on year. Once it became clear that year-round commercial overfishing was a prime component of the steep decline in the population, a 3-month closed season during the breeding period was imposed. This has ensured that at the most critical time in the lifecycle of the species, the groupers are left alone to breed in peace and to perpetuate their species.

Nassau Grouper (Melinda Riger / G B Scuba)

The closed season operates from December to February to maximise the chances of breeding success. As with some other fish species, reproduction occurs around the full moon. The fish gather at spawning sites and the process is at its height around sunset.

Nassau Grouper (Melinda Rogers / Dive Abaco)

10 CONVENIENTLY COLLECTED NASSAU GROUPER FACTS

  • An adult can grow to more than a metre long, and weigh 25 kg
  • They tend to be solitary daytime feeders, eating small fish & crustaceans
  • Their large mouths are use to ‘inhale’ or suck in prey
  • The colouring of an individual can vary from red to brown
  • These fish have little black spots around the eyes (I’ve no idea why).
  • Their habitat is in the vicinity of coral reefs, from shallows to 100 m deep
  • Spawning mainly occurs in Dec & Jan during a full moon
  • Large numbers gather in a single location to mate in a mass spawning
  • These groupers are slow breeders, which compounds the overfishing problem
  • They are easy mass targets at spawning time; hence the need for a closed season

ENDANGERED SPECIES ON ABACO, BAHAMAS (2): KIRTLAND’S WARBLER


Kirtland's Warbler Abaco Bahamas (Bruce Hallett)

ENDANGERED SPECIES ON ABACO, BAHAMAS (2): KIRTLAND’S WARBLER

The rare Kirtland’s warbler (Setophaga kirtlandii) is rightly prized both in its very specific breeding grounds and in its winter migration locations. Abaco is fortunate to be one of these, but they are extremely difficult to find, even with local knowledge. The latest IUCN Red List assessment of numbers of adult warblers (2018) gives a figure of 4,500 – 5,000. The species is categorised as ‘near-threatened’. Numbers are gradually increasing, thanks to a major recovery plan and intensive conservation measures in areas where they nest. 

WHERE THEY LIVE

SPRING & SUMMER Mostly, the KIWA population lives and breeds in very specific areas of Michigan and Ontario, where jack pines are found. As numbers have increased, the range has expanded more widely into Wisconsin and Ohio.

A Kirtland’s Warbler in the jack pines of Michigan (Vince Cavalieri)Kirtland's Warbler, Michigan (©Vince Cavalieri)

FALL & WINTER the population migrates to the Bahamas & TCI, where they tend to choose remote scrub and coppice areas to live until the spring when they return north in April. This range map shows the extremely specialist habitat choices of these migratory birds.

Kirtland's Warbler Range Map wiki

THE MAIN THREATS TO THE SPECIES

  • Mankind is the primary threat. The breeding areas are particularly vulnerable from deforestation and clearance of the jack pines that are essential for successful nesting and breeding – and therefore the survival – of the species
  • Encroachment by development is a major concern (as with so many species everywhere)
  • KIWAs are vulnerable to nest parasitism by brown-headed cowbirds in the breeding areas
  • Their winter habitat is mostly in remote or protected areas, but on Abaco a proposed development in the National Park where they live will probably wipe them out, if built   
  • Overall, habitat degradation at one end of the migration – in particular the breeding grounds – poses a serious risk to the species; at both ends, extinction could loom again

Kirtland's Warbler, Ohio (Tom Sheley)

WHAT TO LOOK OUT FOR?

  • Gray head with a blueish tinge, gray-brown back
  • Yellow throat & underside, with some dark streaking
  • Females are paler and more streaked
  • Split eye rings – white crescents above and below eyes
  • Frequent tail pumping and bobbing

Kirtland's Warbler, Abaco Bahamas (Tony Hepburn)

WHAT DO THEY SOUND LIKE?

Some say ‘chip-chip-chip-too-too-weet-weet’. Elsewhere I have found it claimed that they produce ‘a loud tchip, with song an emphatic flip lip lip-lip-lip-tip-tip CHIDIP‘ (Arnott). I’m not a big fan of phonetic spelling for bird sounds. Here’s a sample for you to assess:

Jared P. Kirtland (1793 – 1877) was an Ohio scholar, doctor, judge, politician & amateur naturalist. He was a man of many and varied interests and talents, not-untypical of his time. In the field of natural history, Kirtland’s name lives on in his warbler & also in a couple of snake species.

ENDANGERED SPECIES ON ABACO, BAHAMAS (1)

May 15th is – was – Endangered Species Day worldwide. I missed it, of course I did. Typical. So, belatedly, here’s the first of a short series highlighting the Endangered Species of Abaco, Bahamas. It will include a couple of species formerly found on Abaco but now extirpated and hanging on in tiny numbers in specific habitats in the wider Bahamas archipelago. Regrettably, much of the endangerment has been caused, or substantially contributed to, by a dominant species that tends to prize self-interest over broader considerations.

ABACO PARROT

Abaco (Cuban) Parrot, Bahamas (Nina Henry)

These gorgeous and beloved parrots nest uniquely in limestone ground burrows in the island’s protected National Park in the south of the island, a vast area of pine forest. They are the big success story of Abaco conservation. I was fortunate enough to become tangentially involved with the parrots just as years of patient research and intensive fieldwork were beginning to impact positively on a dwindling and barely sustainable population (fewer than 1000 birds). Adults and particularly the chicks in breeding season were very vulnerable to the attentions of feral cats, non-native racoons and rats. Nests were protected, cameras were deployed, and predators eradicated.  

Abaco (Cuban) Parrot Nest & Chick, Bahamas (Caroline Stahala)

The work of scientists such as Caroline Stahala was (and still is) supported by local organisations such as Bahamas National Trust and Friends of the Environment Abaco. Local communities lent valuable encouragement and enthusiasm to the project. No one can fail to be uplifted by the sight of a flock of these parrots flying overhead, flaunting their bright green, red and blue feathers that flash in the sunlight. Even the sound of a flock squabbling in the trees like noisy children just let out of school is a joy. Here’s a sample, recorded at Bahama Palm Shores: see if you agree…

CUBAN PEWEE: PICTURE PERFECT ABACO (12)

Cuban Pewee, Abaco, Bahamas (Keith Salvesen / Rolling Harbour)

The Cuban pewee Contopus caribaeus bahamensis (sometimes called the crescent-eyed pewee) is the smallest of the four so-called ‘tyrant’ species found on Abaco. These flycatchers are tiny compared with their kingbird cousins. You can clearly see the tiny hooked tip at the end of the upper beak, which helps to trap caught insects.

Like other flycatchers, the Cuban pewee has distinctive whiskers around the base of the beak. These are in fact feathers that have modified into bristles. They act as tactile sensors that help detect and target aerial insects. The pewee will then dart from its perch to intercept some passing tasty winged morsel (known sometimes as ‘hawking’), returning to the branch to swallow the snack.

Of all small unassuming brownish birds – and there are a great many – I consider the pewee to be one of the prettiest. It is also rewarding to photograph, being inquisitive by nature and as likely to pose for the camera as to fly away.

SEA URCHINS: PICTURE PERFECT ABACO (11)

Sea Urchin, Abaco, Bahamas (Melinda Rogers / Dive Abaco)

As every swimmer knows, or eventually finds out the hard way, it’s not only Blue Suede Shoes that should not be stepped on. But however painful the consequences of a misstep, it’s hard not to find some beauty in an urchin living in a thriving reef environment. The wonderful anatomical diagram by Alex Ries shows everything you could conceivably want to know about one of nature’s most proficient foot-stabbers (if only all such diagrams were presented so simply and clearly).

Sea urchin anatomy (Alex Ries)

The internal organs depicted resemble a bad trip in the bowels of a vacuum cleaner; or (narrow your eyes) an experimental painting from one of the less successful schools of early c20 modern art, soon to be swept aside by Cubism. Note that the mouth is located where you might expect to find the opposite end, and vice versa.

I photographed the urchin test (skeleton) below at Delphi. It was large and almost entirely undamaged (very rare in my experience). The bright faintly greenish white is set off by the palest of pinks. Whatever your view of how creatures came to exist, imagine the creation or evolution of calcium carbonate into a small symmetrical structure as beautiful, detailed and complex as this. If you are short of a lockdown recreation, maybe try to draw it.

BAHAMA YELLOWTHROAT

The Bahama Yellowthroat Geothlypis rostrata  is one of 5 bird species endemic to the Bahamas. Three other endemics found on Abaco are the Bahama Woodstar, Bahama Warbler and Bahama Swallow. The fifth is the endangered Bahama Oriole, now only found in very small numbers on Andros. They once lived on Abaco, but are unrecorded there since the 1990s and are considered extirpated. You can find out more about all these endemic birds together in a nest HERE.

Bahama Yellowthroat, Abaco Bahamas (Gerlinde Taurer)

I’m fond of these birds with their striking Zorro masks. It is one of the few species that I am able to imitate with sufficient accuracy to draw one out of the coppice. Their call is usually described as a ‘wichety-wichety‘. I realise that the talent to mimic it has no other use in life. Here’s a short recording I made – the Yellowthroat is the first and last call of the sample, with other species in between.

CORAL SUNSHINE: PICTURE PERFECT ABACO (9)

coral-in-sunlight-melinda-rogers-dive-abaco

Off the east coast of Abaco lies one of the longest barrier reefs in the world. Some authorities suggest it is the third longest, but the exact ranking of the top dozen coral barriers is a matter for considerable debate. None of the lists I have just checked agree, except that the Great Barrier Reef is the outright winner. I suspect that the problem lies in the loosely generalised description of ‘barrier reef’ and in variations of the appropriate criteria for determining length (it may also depend on who is doing the measuring, of course).

Melinda Rogers of Dive Abaco took this bright sunlit ‘Coralscape’ in the Fowl Cays National Park. It’s a place I have tentatively snorkelled around with great pleasure, despite being in the top dozen most useless swimmers in the world (my appalling underwater videos were disqualified from the rankings for being… rank).

I photographed this little bee a couple of days ago (nb not in Bahamas). Watching it foraging and getting covered in pollen was curiously relaxing, even though it kept moving from flower to flower with no regard to my camera focus. Life is so bizarre at the moment that it was good to see a creature happily getting on with its everyday life.

RED HIBISCUS FLOWER: PICTURE PERFECT ON ABACO (8)

Not much in the way of a caption needed here. As the poet said:  “He that loves not the Hibiscus has a Soul assuredly viscous…”

EASTER BUNNY: OUT STANDING IN ITS FIELD


EASTER BUNNY: OUT STANDING IN ITS FIELD

Rabbit, Dorset UK (Keith Salvesen / Rolling Harbour)

Well, strictly more lying down than standing I suppose, not least because it had sensed me. When I was one-and-twenty* rabbits were a-plenty… and I might have shot it with a bun gun. Then I decided that shooting with a camera was the better way forward. 

*Nod to A.E.Housman; also to my erstwhile online natural scientist friend who led an outdoorsy life and blogged as ‘Out Standing in my Field’, a self-referencing ID never bettered.

LUNAR SEA + CRATERS = SUPERMOON


LUNAR SEA + CRATERS = SUPERMOON

Supermoon - annotated mapping (Keith Salvesen / Rolling Harbour Abaco)

This is not the ‘pink’ supermoon you saw the other day, but one from a couple of years back. I only had a bridge camera with me with a cheapo 1.7 teleconverter, but luckily a sturdy windowsill as well to reduce the shakes (that kind, anyway…). I marked a few prominent features on the image. Some of these took me back to a childhood astronomy book (‘Imbrium!’; ‘Nubium!’) where I learned about stars well beyond Orion, Ursa ma. & mi., and Cassiopeia – about the only constellations I can reliably point to these days. 

This week’s supermoon shone very brightly where I am now, but the moon itself was rather hazy. It certainly wasn’t pink but rather more of a pale cold white. As it turns out, the ‘pink’ doesn’t refer to the lunar colouring anyway, but to the full moon in Spring that occurs when the early-blooming wild pink comes into flower. So, it’s a seasonally-based name and a bit like the harvest moon not being harvest coloured…

PAINTED BUNTING: PICTURE PERFECT ON ABACO (7)


PAINTED BUNTING: PICTURE PERFECT ON ABACO (7)

Painted Bunting, Abaco, Bahamas (Tom Sheley)

Photo: Tom Sheley, taken at Bahama Palm Shores, Abaco

This wonderful and mood-brightening photo was taken by Tom while we were compiling an archive for my book BIRDS OF ABACO  It is one of the most memorable images of the very large number of photographs featured. Every one of them was taken on Abaco (photos taken ‘off-island’ were ruthlessly excluded); and each one in natural surroundings (no seed-trails, recorded calls and so on). Sadly the edition sold out well before Hurricane Dorian so we have been unable to replace any of the many lost copies. However, I am contemplating producing a pdf version of the pre-print draft (a Covid displacement activity). If that goes ahead I will devise a way to distribute it simply, and possibly in return for a modest donation towards the work of Abaco wildlife organisations.

 

GREEN HERON: PICTURE PERFECT ON ABACO (6)


GREEN HERON: PICTURE PERFECT ON ABACO (6)

Green Heron, Abaco, Bahamas (Keith Salvesen / Rolling Harbour)

We saw this green heron (Butorides virescens) at Gilpin Pond, South Abaco. It’s an excellent location for waterbirds and waders, although in hot weather when the water level drops an algal bloom colours the water with a reddish tinge. The coppice around the pond is good for small birds; parrots pass through on their daily flights to and from the forest; and the beach the other side of the dunes can be excellent for shorebirds. 

We watched this heron fishing for some time. I took quite a few photos of the bird in action, including its successes in nabbing tiny fish. However there were two problems with getting the perfect action shot. First, the bird’s rapid darts forwards and downwards, the fish grabs, and the returns to perching position with its snack were incredibly quick. Secondly, my slow reactions and innate stupidity with camera settings militated against a sharp ‘in-motion’ image to be proud of. So I’m afraid you get the bird having just swallowed its catch.

SPERM WHALE BONES & RESEARCH: LIFE AFTER DEATH


SPERM WHALE BONES & RESEARCH: LIFE AFTER DEATH

I made this short video last year at BMMRO HQ, Sandy Point, Abaco. A sperm whale had stranded earlier in the year, and after the necropsy some of the bones were taken from the beach for research. In order to clean them, the bones were sunk and anchored to the seabed offshore in quite shallow water. Strandings are always sad, of course, but  it is good to know that even after death the creature makes an important contribution to scientific research. In a sense, it has life after death.
