ON THE WING: BLACK-NECKED STILTS, ABACO, BAHAMAS

ON THE WING: BLACK-NECKED STILTS, ABACO, BAHAMAS

Black-necked stilts Himantopus mexicanus may be the most elegant shorebirds you will ever see. They are permanent residents on Abaco and not uncommon where they are found. It could be on a beach; more likely it will be in or around brackish ponds. It won’t be in the pine forest or coppice.

The rather disorganised stilt flying in the header image rather undercuts my claim for elegance, I realise. The image above of the bird at full stretch against a background of waves gives a much better idea of the beauty of this species.

Gilpin Pond is a good place to see stilts, and in summer they nest around the perimeter. A word of warning: they may be aggressive in the breeding season. I got too near a nest once and the female shouted at me then flew straight at my head. I hadn’t even realised there was a nest there until this happened, so her actions rather give the game away.

In common with some smaller shorebird species – for example, plovers and killdeer – the stilts have another defensive method to protect their young, a so-called ‘distraction display’. When their nest is under threat, one of the adults will pretend to have a damaged or broken wing and so be unable to fly. It will flutter feebly along the ground, moving further and further away from the nest, diverting attention from it. It’s an amazing sight to watch the tactic in action. Check out this video to see examples of this behaviour.

BANANAQUITS: AHEAD OF THE CURVE?

February 15, 2020 by Rolling Harbour

BANANAQUITS: AHEAD OF THE CURVE?

Bananaquits (Coereba flaveola) are small, colourful, and delightful birds of the coppice and garden. Besides their obvious attractiveness, the birds have in recent years enjoyed an uniquity: the status of being the sole species in the family Coerebidae.

However this singular status has really been a kind of avian parking place due to past, present (and doubtless future) uncertainty of the right category for these birds. Like so many avian species these days, they are subject to the rigours and vagaries of continual reclassification by the ornithological powers-that-be.

Bananaquits are, broadly speaking, passerines – essentially birds that perch. The nominal ‘passer’ was specifically awarded to sparrows by BRISSON, a contemporary of Linnaeus. Recently, bananaquits have suffered mysterious migrations of their classification ranging from the generalised ‘passerine‘ to the vague incertae sedis (= ‘uncertain group‘) to uncomfortable inclusion with tanagers / emberizids.

The debate over the appropriate classification for this pretty little bird (of which there are many subspecies in the broad Caribbean region) – rumbles on. A new way to confuse the issue is the suggestion that the bananaquit should be split into 3 species. In some areas, I believe this has happened at least informally.

Elsewhere there are doubters, sceptics, and champions of other group inclusions. The most obvious beneficiaries of all this will be dedicated birders, who may end up with two extra species to add to their ‘Lifer’ lists. Personally I’d like to think that the birds themselves will stay ahead of the curve in their own category, maintaining the mystery of their precise status while humans argue about what to call them.

PIPING PLOVERS: ABACO’S RARE WINTER RESIDENTS

January 27, 2020 by Rolling Harbour

PIPING PLOVERS: ABACO’S RARE WINTER RESIDENTS

PIPING PLOVERS Charadrius melodus are specialist shorebirds on Abaco. For a start, they are very rare – the IUCN listing suggests a population of only 8000 mature birds in the world. They are both scarce numerically and limited geographically.

These tiny plovers breed only in a few defined areas of North America – areas that are rapidly reducing mostly for all the usual depressing human-derived causes, for example the exercise of man’s alienable right from time immemorial to drive vehicles all over the nesting sites in the breeding season. The birds are unsurprisingly IUCN listed as ‘near-threatened’.

Piping Plovers breed and nest in the north and produce their chicks. The chicks soon learn to be independent and to fly. From about mid-July, those adults and chicks that have avoided the wheels of the SUVs, the unleashed dogs in the areas set aside for nesting, and the more natural dangers from gulls, start to get the urge to fly south for the winter. The range of their winter grounds is shown in blue on the range map above. It includes the Bahamas in general and Abaco in particular.

Q. WHY ARE THEY CALLED PIPING PLOVERS? A. BECAUSE OF THIS!

Paul Turgeon

I will return soon to the significance of the safe, clean beaches of Abaco and the healthy habitat for the survival of this remarkable little bird. For now, I’ll simply say that loss of habitat, and an increase in the nature and / or extent of environmental threats at either end of the migration, may seriously damage the survival of the species. It follows that habitat degradation at both ends of the migration could see the IUCN listing progress rapidly to vulnerable, endangered, critically endangered and… well, the next category is ‘extinct in the wild’.

If you are interested in shorebirds, in bird migration, in research into bird movements, and in the reason migratory birds are banded, you can find out more at ABACO PIPING PLOVER WATCH. This is the only season-long research project in the Bahamas, and involves Citizen Scientists on Abaco in the south working with partner Proper Scientists in the breeding grounds in the north. Early next month I will write a follow-up post on these topics.

The photographs in this post were taken a few days ago on the long crescent of beach at Winding Bay, Abaco by Lisa Davies. Her contribution is precious because the APPW project mentioned above was for many reasons in danger of stalling as the result of the devastating effects of Hurricane Dorian on almost every aspect of island life. Lisa’s discovery of a small flock of a dozen plovers in the sunshine has given impetus to the project – and has resulted in some superb photos.

WRY ‘CUDA & SARDONIC SMILES, ABACO BAHAMAS

January 19, 2020 by Rolling Harbour

WRY ‘CUDA & SARDONIC SMILES, ABACO BAHAMAS

There’s no doubt about it, barracudas have a particularly unwelcoming look to them. They exude menace. There’s something about the torpedo shape, the primitive head, and the uncomfortably snaggle-toothed grin-with-underbite that suggests a creature not to be underestimated.

And that smiley mouth – rather scornful and derisive, is it not? A powerful creature in its element, where you are the intruder… and it sees it like that too. An adult barracuda may grow to nearly 6 foot long. Your are only temporarily of its world, and (it observes) you are keeping your distance.

The dental arrangements of a ‘cuda are a wonder in themselves. The teeth are razor sharp; an orthodontist’s nightmare because they are all different sizes and grow at different angles. Some are conventionally set in the jaws, but some actually grow from the roof of the mouth. There are ‘normal’ sized teeth interspersed with wicked-looking fangs that randomly grow facing forwards, backwards and sideways.

WHY THE UNTIDY MOUTH FURNITURE?

The name Barracuda is thought to derive from the Spanish word barraco meaning (in one of its senses) “overlapping teeth”. The jaws that contain the teeth are strong, and the underbite adds to the effectiveness of ‘cuda predation. Prey is highly unlikely to escape once caught. When the jaws snap shut, the sharp angled teeth – particularly the back-facing ones (cf fishhook barbs) prevent the victim from pulling away. Then the munching and shredding can begin inside what is essentially a perfectly equipped multi-bladed mincing machine.

The white-cheeked (‘Bahama’) pintail Anas bahamensis (aka ‘Bahama duck’) is everyone’s favourite dabbling duck. Or at least it ought to be. And when there are ducklings swimming with the adults, there is no emoticon yet devised that will convey the extremes of cuteness achieved.

BABY SPERM WHALE, ABACO, BAHAMAS: HOPE FOR A NEW DECADE

BABY SPERM WHALE, ABACO, BAHAMAS

HOPE FOR A NEW DECADE

Looking back at 2019, one of the most enjoyable posts to put together featured an adult sperm whale with a neonate calf. The wonderful photos were obtained last summer during 2 research trips in the deeper water off the south coast of Abaco by the Bahamas Marine Mammal Research Organisation (BMMRO) It seems fitting to greet the new decade with a revised version of my original post. There’s optimism in these images, and more generally in the recovery in some areas of the savagely depleted whale populations of past decades. I’d like to think that a smiling baby whale holds out hope for the 2020s.

Sperm Whale baby (neonate) Abaco Bahamas (Charlotte Dunn / BMMRO)

These are just some of the BMMRO research team’s images and footage of the baby sperm whale investigating the underwater world it has just been born into. Hopefully it will flourish and live for decades. If it does not, the overwhelmingly likely cause will be mankind, either directly or indirectly.

‘DEEP DIVERS IN DIVERS DEEPS’: CUVIER’S BEAKED WHALES

December 13, 2019 by Rolling Harbour

‘DEEP DIVERS IN DIVERS DEEPS’: CUVIER’S BEAKED WHALES

JOURNEY TO THE WORLD’S MIDNIGHT ZONE

Please join me in a dive down from the sparkling surface of the turquoise sea to the twilight zone at 200 meters. You’ll pass plenty of sea-life on the way: manatees grazing on seagrass just below the surface; reef fish, barracudas, reef sharks, mahi-mahi, maybe an orca at 100 meters. Other familiar creatures that are found even lower include a few reef fish, some shark species and green sea turtles. You are now running out of clear light.

As you descend from 200 meters the waters become murky, then inky. The variety of inhabitants and their numbers are gradually decreasing. There are eels, some sharks, squid, stranger deep-water creatures. You may be surprised to see familiar bottlenose dolphins, recorded as diving nearly 300 meters. At 332 meters you will equal the deepest point any human being has ever scuba-dived (Ahmed Gabr 2014). There is little light, but you still have a long way to go to reach your goal.

Descending still deeper, species and numbers continue to thin out. Around the world the limits of larger recognisable species is being reached – more shark species, tuna, chinook salmon, emperor penguins, swordfish, the few corals that can survive the depth. As the light fades to black, giant creatures and strange fish abound. Huge crabs. Sunfish. The (no-longer-extinct) Coelocanth. Massive octopuses.

Deeper down, nearing 1000 meters now, there are still some familiar species. Leatherback turtles; Baird’s beaked whales (nb not in the Atlantic); and at 920 meters, the deepest recorded sperm whale dive. It’s pitch dark: you have reached the level that sunlight never penetrates. You are in the Midnight Zone.

DEEP OCEAN DWELLERS

In black depths below 1000 meters, creatures have adpated to create their own light sources – so-called bioluminescence. This is the realm of the self-lit anglerfish, the blobfish and the goblin shark. It’s the Attenborough world of deep sea exploration. The geology is changing: there are hypervents, volcanic rocks, heavy metals. Below are the deep ocean-floor trenches. Yet there are still recognisable species down here, diving astonishingly deep to 1800 meters to feed – not least the narwhal which makes this trip several times a day to feed.

We need to quicken up the descent now – we have to get down nearly twice as far as this to reach our destination…

We pass large squid and isopods, the deepest diving shark – the Greenland, the 10 meter-long 700 kilo colossal squid – yet amazingly there are marine mammals yet to be encountered: at 2400 meters we drift past a huge elephant seal. There are evil-looking creatures down here with names to match – devilfish, viperfish, black swallowers that can eat a larger fish whole, vampire squid and zombie worms.

At 3000 feet, we finally end our quest. We have reached the depth to which the world’s deepest diving mammal has been recorded: the Cuvier’s beaked whale Ziphius cavirostris

Cuvier’s beaked whales, or “goose-beaked whales,” are not rare. For a start, unlike many beaked whale species, they inhabit most oceans and seas in the world and have the most extensive range. Unsurprisingly therefore, they are one of the most often sighted beaked whale species and one of the best studied.

FIN FACT

You may be wondering about the pressure exerted on a creature at a depth of 3000 meters. The answer is, an astounding 300 atm (atmospheres), enough to crush all but the hardiest and best adapted of species. The question how these whales manage to survive at such a depth is one for the future…

The Cuvier’s is one of the 3 beaked whale species found in Bahamas waters. Like the rarer Blainville’s and Gervais’s beaked whales, the Cuvier’s is the subject of ongoing research by the BAHAMAS MARINE MAMMAL RESEARCH ORGANISATION BMMRO.

The research into marine mammal populations in the Bahamas and far beyond is focussed on the massive increase in single and mass strandings, including recently in a remote area of Scotland (Hebrides) where more than 40 Cuvier’s were washed ashore.

One significant area of research examines the effect on marine mammals of man-made noise. There is plenty of it in the world’s oceans caused by noise pollution in and around shipping channels that traverse marine mammal migration, feeding and breeding grounds; naval surface and submarine exercises; seismic surveys, sonar waves and undersea resource investigations. The evidence of sound / acoustic damage as an additional hazard for marine mammals is starting to look very clear.

ABACO HUMMINGBIRDS: WHAT’S THE NEWS?

November 24, 2019 by Rolling Harbour

ABACO HUMMINGBIRDS: WHAT’S THE NEWS?

SIGHTINGS POST-DORIAN

Since the hurricane struck nearly 3 months ago, order is slowly being imposed on the chaos. Debris is being removed in vast quantities, building repairs are in progress, shops and some businesses are starting to open – and even (only last week) a bank.

Specific bird news from Abaco post-Dorian is sporadic, with people having plenty of other concerns at the moment and for some time yet. The wellbeing of the parrots has been checked during a scientific survey last month. There is infrequent but positive news of the shorebirds, especially of the piping plovers that are counted each winter season. There have been some reports of the warblers (of which there are an astonishing 38 species recorded for the Island and its cays).

As yet, I have seen no recent mentions at all in SocMed about the hummingbirds – the endemic Bahama Woodstar (#1 F; #2 M); and the Cuban Emerald (#3 F; #4 M). Are they around? Is anyone seeing them darting about like jinking bullets or feeding on flowers on the hover? I’m not on-island, so I’d be very pleased to know: are the hummers still humming?

AN OCTOPUS’S GARDEN, BAHAMAS

November 12, 2019 by Rolling Harbour

AN OCTOPUS’S GARDEN, BAHAMAS

Many of us, from time to time, might like to be under the sea, warm below the storm, swimming about the coral that lies beneath the ocean waves. Though possibly not resting their heads on the seabed. This undeniably idyllic experience would be perfected by the presence of an octopus and the notional garden he lives in. Enough to make any person shout and swim about – and quite excessively at that.

The extra ingredient here is that these photographs were taken on the reef off the southern coast of Grand Bahama last week, less than 2 months after the island (along with Abaco) was smashed up by Hurricane Dorian. Thankfully, Grand Bahama Scuba has been able to return to relative normality and run diving trips again. Moreover, fears for the reefs have proved relatively unfounded. These images suggest little damage from the massive storm. The Abaco reefs have not yet been able to be assessed in any detail.

The feature creature here was observed and photographed as it took it a octopodic wander round the reef. The vivid small fishes are out and about. The reef and its static (technically ‘sessile’) life forms – corals, anemones and sponges – look in good order. The octopus takes a pause to assess its surroundings before moving on to another part of the reef.

THE PLURAL(S) OF OCTOPUS REVISITED

A long time ago I wrote a quasi-learned disquisition on the correct plural for the octopus. There were at least 3 possibilities derived from Greek and Latin, all arguable but none so sensible or normal-sounding as ‘octopuses‘. The other 2 are octopi and octopodes. If you want the bother with the details check out THE PLURAL OF OCTOPUS.

There’s an aspect I missed then, through rank ignorance I’d say: I didn’t check the details of the Scientific Classification. Now that I am more ‘Linnaeus-woke’, I have two further plural candidates with impeccable credentials. Octopuses are cephalpods (‘headfeet’) of the Order Octopoda and the Family Octopodidae. These names have existed since naturalist GEORGES CUVIER (he of the beaked whale found in Bahamas waters) classified them thus in 1797.

RH ADVICE stick with ‘octopuses’ and (a) you won’t be wrong (b) you won’t get into an un-winnable argument with a pedant and (3) you won’t sound pretentious

‘LIKE’ THE CLAPPERS: ON THE RAILS IN ABACO

November 9, 2019 by Rolling Harbour

‘LIKE’ THE CLAPPERS: ON THE RAILS IN ABACO

CLAPPER RAILS Rallus crepitans 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. They are creatures of the margins rather than open ground. You may come across one foraging secretively, beak-deep in the mud.

Tom Sheley’s wonderful photos featured here of a preening clapper rail were taken during our backcountry explorations to locate and photograph species for BIRDS OF ABACO. By being both patient and an early riser, Tom managed to capture this fine bird engaging in some quality grooming. The one below is ‘vocalising’ – known in rails as ‘rousing’ – in mid-preen.

Clapper rails are capable of swimming and even of flying if they choose to. However the most likely activities you are likely to observe will be skulking, picking their way through marginal vegetation, or (if you are lucky) doing some beak-deep foraging in the mud. Occasionally they run, a process that looks endearingly comical and which possibly gives rise to their name.

It almost goes without saying nowadays, but the biggest threat to these rather charming inoffensive birds is habitat loss. Which is to say, mankind either directly or indirectly. 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. As they will if the climate we are unarguably changing ruins their unobtrusive lives.

COMPULSORY LINGUISTIC STUDY

When I last wrote about this species its binomial name was Rallus longirostris ie simply ‘long-beaked rail’. Since then the increasingly frenetic annual turmoil of official AOU shuffling species about and messing with their names has resulted in the clapper rail being re-designated Rallus crepitans or ‘rattling / rustling rail’, I assume from the call. There are other rail-name innovations that, reading about them just now, made me crack open a beer instead of wanting to tell you about them.

OPTIONAL LINGUISTIC DIVERSION

“TO RUN LIKE THE CLAPPERS”. This phrase seems to be fairly recent, most likely originating as military (?Air Force) slang early in WW2 or possibly from earlier conflicts. Some suggest it is a rhyming slang 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. This derivation as a link to the bird seems tenuous at best.

YELLOW-HEADED BLACKBIRD: A NEW SPECIES FOR ABACO, BAHAMAS

October 26, 2019 by Rolling Harbour

YELLOW-HEADED BLACKBIRD: A NEW SPECIES FOR ABACO, BAHAMAS

In the aftermath of the awesome (in its original meaning) power of the hurricane, Abaco is slowly rising from the remnants of its peaceful slow-paced beauty. The loss of human life, and the damage to survivors, to animals, to property and to precious possessions is unimaginable. By way of contrast, in the UK a flood that inconveniences a SUV owner in an affluent area may well make the local paper*; and possibly local TV news if the wait for a tow-truck takes an hour or so.

BIRDS are providing some cheer and a welcome diversion for many islanders. On SocMed there are plenty of chats** going on daily about the parrots, emerging winter warblers, occasional shorebirds and so on. Feeders are back in use with seeds and nuts (nb please no peanuts). Photos are being taken, shared and enjoyed.

Over the last few days, red-winged blackbirds have been a visible and indeed audible presence in various settlements. Their characteristic ‘rusty gate-hinge’ call is unmistakeable, whether in the coppice or heard deep in the mangroves 4 miles off-shore from a skiff in the Marls. Let’s progress to a great discovery and a most perfect example of ‘birds of a feather’ literally ‘flocking together’.

YELLOW-HEADED BLACKBIRD

THE FIRST EVER SIGHTING & PHOTO ON ABACO

The photograph above was taken on October 20 in Little Harbour, Abaco by Bernard Albury. A pair of red-winged blackbirds, male and female, were on the feeder in his garden. With them was a rather more colourful blackbirdy-type bird – a juvenile yellow-headed blackbird Xanthocephalus xanthocephalus. Bernard’s photo is the perfect example of how a quick shot with a phone can make all the difference between a vague description of a bird for ID (oriole? bobolink? weird warbler?), and having clear visual clues to work with.

A NEW SPECIES REPORTED, YOU SAY? HOW CAN YOU POSSIBLY TELL?

The news of this exciting sighting quickly reached bird scientist Ancilleno Davis of (among many organisations) Birds Caribbean. ID was established, and the news soon spread via FB shares. This bird was a very long way east of its normal range, and I thought that it might possibly be a first for the entire Bahamas; probably a first for Abaco itself; and almost certainly the first photo of a YHBL. Then it was a question of cross-checking data in books such as Tony White’s comprehensive guide; online in specialist bird websites; and with the Bahamas bird experts such as Woody Bracey and author Bruce Hallett.

Tony White, [random], Bruce Hallett, Woody Bracey

SO WHAT’S THE ANSWER?

Simple. Bernard Albury has, in his own garden in Little Harbour, discovered the first Yellow-headed Blackbird ever recorded for Abaco. Furthermore, his photo is very probably the first-ever image (by which I mean only image) of a YHBL for the entire Bahamas.

BUT HOW CAN YOU TELL THERE HAVEN’T BEEN LOTS OF OTHERS?

The first step is to check an authoritative range map of the species in question. Audubon and Cornell are the go-to authorities for this purpose, though tbh there’s a great deal to be said for using Wiki as a first port of call for a new bird and its details. People rarely bother to mess with the avian articles on Wiki, there’s not a lot of fun it it. For the Yellow-headed Blackbird, the sheer distance to Abaco makes a visit from one highly unlikely. The second step is to check online sightings reports uploaded to eBird by birders ranging from the enthusiastic amateur to the vastly experienced professional. For an unusual bird, the reports are invaluable in establishing relative rarity. The previous online reports for YHBL in the Bahamas were of a couple of sightings of single birds in the Freeport / West End area of Grand Bahama. These were in 2006 by bird expert Woody Bracey; and in 2012.

Finally, cross-check in the most thorough bird guides of the area. In this case, Tony White included GB sightings YHBLs in his meticulous chart but none for Abaco. No other authority – Bruce Hallett for example – has noted a sighting report for Abaco; Woody also believes this to be a first, and he should know, having found the first ever Bahamas one in 2006.

I KNOW WHAT TO LOOK FOR NOW, WHAT DO THEY SOUND LIKE?

First, here’s the familiar call of a red-winged blackbird

Here are two examples of the much harsher call of the YHBL, described variously as “the worst song of any North American bird, a hoarse, harsh scraping”; and “an awful sounding raspy whine”.

SOME NICE PICS OF BAHAMAS WILDLIFE… WHILE TECHIES LABOUR

SOME NICE PICS OF BAHAMAS WILDLIFE…

WHILE TECHIES LABOUR

Western Spindalis, Abaco Bahamas (Keith Salvesen)

I’m never quite sure how far it’s permissible to go beyond ‘really pissed off’ about a tech problem. Anything much stronger seems a bit indulgent both in itself and especially when measured against the far-reaching despair experienced by many in far more important areas of life.

I am just having a huge “Grrrrrrrrr” moment because my complex blog menu, with 3 rows of headings and carefully curated nests of drop-downs under each, has been scrubbed by persons or AI unknown. It’s several years of cumulative and (mostly) pleasurable organisational work up the spout.

As a Brit, may I be permitted to say ‘bother’. Or maybe ‘Dash it all?’ Or declare that I’m a mite cheesed orf? To which a fair response would be “it’s just a trivial inconvenience, get over it…”

For the moment, here are some nice pics to enjoy, all taken on Abaco. I’m happy to say that right now, 7 weeks since Dorian, there are promising signs that in some areas of Abaco, the birds are starting to show themselves – including a few winter warblers. See you the other side of rethinking my Menu…

ABACO PARROTS, SURVIVAL & RESEARCH: POST-DORIAN UPDATE

October 11, 2019 by Rolling Harbour

ABACO PARROTS: SURVIVAL & RESEARCH

A POST-DORIAN UPDATE

The unique and symbolic parrots of Abaco have become quite a focus of attention now that some kind of normality is returning to the devastated island. Utilities and supplies are being sorted out gradually (and with unavoidable setbacks). There are some signs of optimism in the air – and some parrots too.

SO, AFTER THE HURRICANE ARE THERE ANY PARROTS AROUND?

At Bahama Palm Shores, the most ‘parroty’ of all the communities in south Abaco, Tara Lavallee was the first to see – and photograph – a pair on Sep 25th, nearly 4 weeks after Dorian struck. Over the next 10 days, and thanks to Janene Roessler’s work, I compiled a record of reports and sightings and mapped them. There were 12 in all, from Crossing Rocks in the south to Winding Bay in the north (25 – 30 miles as the parrot flies).

Abaco Parrot, Bahamas after Hurricane Dorian (Tara Lavallee)

THE FIRST POST-DORIAN PARROTS

ABACO PARROT SIGHTINGS MAP BETWEEN SEP 25 AND OCT 4

The interactive map works like this (in theory at least). You can expand the map using the cursor, double clicks, or 2 fingers until you have enlarged the target area sufficiently to click on the individual coloured parrots. For each one, the sighting details are given with as much information as was available. The colour key is this:

Maroon – First sighting
Blue – sighting with some details (eg numbers)
Yellow – sighting with little detail
Purple – flocks of 10 +

IS ANYONE LOOKING AFTER OUR PARROTS?

By the turn of the century the parrot population had become unsustainable, having fallen below 1000, and their extinction was imminent. Since then, many organisations (eg BNT) and people have been involved in the reversal of the decline through intensive anti-predation and conservation measures. All this work continues so that the future of the parrots is assured. The rough estimate pre-Dorian was of c4000 birds.

WHAT ABOUT NOW, AFTER THE STORM?

As I mentioned in a previous post, a survey team including Abaco’s former parrot scientist Caroline Stahala Walker (now with Audubon) were planning a trip to Abaco once access became possible. They have just arrived on-island, and will be assessing the effect of Dorian both on the wildlife and on the habitat. This will include the parrots, and other ‘signal’ birds too. I expect these will include the endemics, the speciality birds (eg the woodpeckers), and some shorebirds including (I hope) piping plovers. They will also bring feed and feeders and give advice about care of the birds.

Caroline wrote “I wanted to let everyone know we have a team going to Abaco for surveys and setting up feeders starting tomorrow. The logistics were tough enough to piece together but it certainly would not have happened without all of your help. I will post pictures and update after the trip, not sure what internet situation will be like while there. Thanks everyone! You made this happen.”

CAROLINE’S GO FUND ME PAGE: CLICK THE LOGO

Some years ago Caroline and I put together a tiny booklet about the parrots, mainly for the benefit of guests and visitors at the Delphi Club. We asked for $5 – 10 donations for the birds. There were 2 editions. Later, I turned it into an ‘moving booklet’ with added music (that you can turn off!). Some people may have seen this elsewhere online recently. The middle section on the parrot nests in the National park, the chick-care, and the associated breeding research may be of particular interest. The pics are cute!

Thanks to all who contacted me to say there was an issue with the version of this booklet originally posted – a ‘privacy settings’ problem, as it turned out. I’ve exchanged it for a different format version, which is also a bit clearer…

THE NATURAL HISTORY OF THE BAHAMAS: A FIELD GUIDE

On October 15th Cornell University Press publishes the first-ever comprehensive field guide to the terrestrial natural history of the Bahamas*. This monumental study has been years in the devising, researching, writing and production. The five authors are all eminent natural scientists in their specialist fields, and well-known far beyond the Bahamas. They combine to bring authoritative yet accessible scholarship to the pages. This book will undoubtedly become the go-to standard field guide for the Bahamas for decades. Furthermore, its breadth of scope will reach adjacent territories beyond the archipelago. *With a few exceptions for ‘signal species’, ocean-life is not included

The new guide comprises an encyclopaedic 464 pages with 768 colour photos plus line drawings, maps, charts and tables. The subject-matter begins with a detailed introduction that encompasses Geology, Climate, Habitat, Biogeography, Human History and Conservation. This establishes the wider context for the pages that follow.

The guide is then divided into discrete sections that cover Fungi, Flora / Plants, Invertebrates, Amphibians, Reptiles, Birds, and Mammals (of which there are very few in the Archipelago, and few of those endemic). As a general observation, you simply will not believe how many species and subspecies there in some of the categories.

In expressing my enthusiasm for the new guide, I ought to declare my interest. From a fairly early stage of the project, I helped in two ways: sourcing / supplying images; and helping with proofing / editorial work of the sort common to all such diverse reference works.

Right now, in the aftermath of the disastrous impact of Hurricane Dorian, the northern Bahamas (Abaco & Grand Bahama) are still at the very earliest stages of a return to normality. Some areas are still without reliable water or power. The extent of the devastation suggests that the new ‘normality’ will inevitably be rather different from the past. It is sobering to consider that, since this field guide went to press, the balance of nature on two of the most diverse islands for wildlife in the archipelago has already changed significantly – and in some instances that change may well be for good.

I have a hope – and there are some signs already – that people’s interest in the wildlife around them provides a degree of comfort in hard times. Further south in the Bahamas, the other islands will each have had their own similar extreme weather experiences many times. The wildlife is varied but with similarity throughout the extensive chain of 700 islands that make up the Bahamas, with a vertical length of over 500 miles and covering more than 8000 square miles of land and sea. The familiarity of many of the plants, trees, butterflies, and birds binds the diverse islands together to create a common experience.

IS THIS THE REAL LIFE? OR IS THIS JUST FANS AT SEA?

October 4, 2019 by Rolling Harbour

IS THIS THE REAL LIFE? OR IS THIS JUST FANS AT SEA?

I wrote the original post on this theme, with its somewhat Bohemian and rhapsodic title, a while back. It was put together at a time of sunshine, normality and optimism. The 2019 hurricane season was far in the future, and the prospect of one – let alone two – of the finest islands in the Bahamas being virtually eradicated overnight was unthinkable.

Right now, in the aftermath of the devastation wrought by Hurricane Dorian, and as the communities gradually start on the long road to recovery, the priorities remain personal and community safety, food, fresh water, medical supplies and access to all the other necessities that the major relief operation has so effectively enabled. However, as gradual improvements to daily life are achieved, so a degree of interest in the natural world is returning.

The despoliation of the land is there for all to see, visible even from space. As yet – as far as I know – no one has had the time or opportunity, or even a boat and the right equipment to investigate below the surface of the sea. What of the reefs: the bright darting reef fish; the larger denizens of the deep; the corals, sponges and anemones? The massive Cat 5 storm caused an unprecedented 23′ surge. It’s hard to see how the reefs can have remained unaffected, and there must be the possibility that the THIRD LARGEST BARRIER REEF in the world will have been altered irrevocably.

Since Dorian, the related organisations have been unable to operate. Abaco’s ‘Dive Abaco’ was virtually annihilated along with the rest of Marsh Harbour. Grand Bahama Scuba has just reopened, although it may take a while before dive trips are anywhere back to normal. This post contains beautiful photos from both the Melindas concerned, taken in happier times before the dark cloud swept over the islands just one month ago.

NOTES FROM THE PRE-DORIAN PAST

The waters of Abaco teem with myriads of fish that depend on the coral reefs for shelter and safety, for breeding, for growing up in, and for nourishment. Sea fans (or gorgonians, to use the technical name) are animals too. They may look like plants and stay rooted to the spot, but like anemones these ‘soft corals’ are creatures of the reef and essential indicators of its health.

At the moment it can still be said that the static (‘sessile’) members of the Abaco reef community are relatively unscathed by the impact of (and I don’t want to get into any arguments here) whatever causes mass bleaching and the death of reefs elsewhere in the world.

The purple sea fan Gorgonia ventalina (classified by Linnaeus in 1785) is one of the most common species of sea fan, and a spectacular one at that. The main branches are linked by a lattice of smaller branches. Below the ‘skin’ is a skeleton made of calcite compounded with a form of collagen.

Sea fans are filter-feeders, and have polyps with eight tiny tentacles that catch plankton as it drifts past. They develop so that their orientation is across the prevailing current. This maximises the water passing by and consequently the supply of food as the fans gently wave in the flow.

Gorgonians have a chemical defence mechanism that protects against potential troublemakers. The main effect is to make themselves unpleasant to nibble or uproot.

One species impervious to this deterrent is the fascinating FLAMINGO TONGUE SNAIL (more of which quite soon). Other ‘safe’ species include the fireworm and BUTTERFLYFISHES.

One benefit of sea fans to mankind is that their defensive chemicals have been discovered to provide the basis for drug research and development, specifically in the field of anti-inflammatories. Another benefit, of course, is that they are very beautiful to look at. And in bad times, that can only be good .

Most of the photos featured are by courtesy of Capt. Keith and Melinda Rogers of the well-known local scuba dive and snorkel centre DIVE ABACO, located in central Marsh Harbour. As prime enablers of reef exploration in Abaco waters, it can truly be said that they too have plenty of fans.

FINALLY, A SPECIAL FAN FOR ABACO AND GRAND BAHAMA

BEAUTIFUL BIRDS OF ABACO, BAHAMAS (1): PRAIRIE WARBLER

BEAUTIFUL BIRDS OF ABACO, BAHAMAS (1): PRAIRIE WARBLER

The increasing flow of reports of recent bird sightings on Abaco seems to confirm the theory that in times of crisis and of recovery from disaster, people gain strength from the natural world that surrounds them. The bright flash of a parrots wings; the hoarse squawk of a West Indian Woodpecker; the unmistakable cheery call of the thick-billed vireo; the ‘peep’ of a shore-bird – all these can bring comfort in troubled times.

Right now, social media on Abaco, and radiating far beyond, is alive with more encouraging news after the storm, not least about the gradual re-establishment of normality as utilities and services are restored, movement becomes more possible, and plans for repairing the past and designing the future can begin to be made.

This post features photos of Prairie warblers taken on Abaco by Gerlinde Taurer, contributor to THE BIRDS OF ABACO. It is the start of a short series that will focus on a single species and feature gorgeous photos, all taken on Abaco. These bright little warblers are common winter residents and in normal times their Fall arrival would be well under way – along with some 30 other species of warbler that make Abaco – and the Bahamas generally – their winter home.

The rich diversity of the avian life of Abaco is truly astonishing: from residents to migratory species, from tiny to huge, from frequently encountered to very rare. Every bird (yes, even the reputedly ‘dull’ black-faced grassquits) has its own beauty and character. Even a small brown bird may have a lovely song. In non-storm circumstances, it would not be unusual for an amateur birder to encounter upwards of 40 species during half a day in the field – especially with binoculars. I hope that on a shattered island, appreciation of the lively and varied birdlife is already making a small yet positive contribution to the recovery.

ABACO BAHAMAS POST-DORIAN: HOPE & THE ICONIC PARROTS

September 27, 2019 by Rolling Harbour

ABACO BAHAMAS POST-DORIAN: HOPE & THE ICONIC PARROTS

As the intensive Hurricane Dorian relief operation continues on a devastated Abaco, the extent of the destructive power of the huge storm is all too evident. Gradually restored communications and the availability of social media have circulated far and wide the awful photos and aerial views of the smashed island, and the tragic stories of loss and desolation. Accounts of astonishing courage, determination and generosity are for all to see. And, nearly 4 weeks later, we have early signs of recovery and grounds for hope in a stricken land.

For the last 10 days or so, inquiries about Abaco’s birds and other wildlife have begun and are increasing daily. I take this as a sign that people are at last able to look slightly beyond the immediate horrors of the storm to the brighter horizon of the future. The iconic parrots are the principle concern, and finally – finally – I have some good news to bring. Here it is, in all its glory.

I have been waiting anxiously to pick up the first reports of parrot sightings – or even of their raucous squawks. This iPhone photo was taken yesterday at Bahama Palm Shores by Tara Lavallee. You are looking at the first photograph of the parrots since the end of last month. This pair were apparently wary and jumpy – quite unlike the unselfconscious rowdy birds with which we are so familiar. There was a sighting near Casuarina, too. It looks as though the parrots are returning.

WHERE HAVE THE PARROTS BEEN IN THE MEANTIME?

The parrots live and breed in the Abaco National Park right down in the south of the island. This is a vast area of pine forest that gives way to scrubland as it nears the coast. The assumption is that the approaching storm will have driven the parrots deep into the forest where, happily, they will have been some distance away from the destructive path of the hurricane. Many creatures can sense the approach of bad weather from changes in the air around them. This may trigger an instinct to head for home some time before the threat arrives.

ONCE THEY GET THERE, WHAT DO THEY DO?

They lie low. The parrots have an additional and most unusual way to stay safe. They can avoid the dangers of adverse weather and even forest fires because they live and nest underground in limestone caves deep in the National Park.

HOW RARE IS THAT?

The Abaco parrot (as opposed to its tree-nesting cousins in Inagua and in small numbers in Nassau) is unique in this respect, certainly in the northern hemisphere. There are half-a-dozen mostly inter-related species in the Antipodes that nest underground, but that is all. Even if the caves get flooded, limestone is a permeable rock and water will dissipate. And as for fires, the holes are deep enough for the flames to pass over them. Tree-dwellers are far more vulnerable.

DOES THIS MEAN THE PARROTS ARE ALL SAFE?

It’s much too early to judge, because there is another vital component in their survival: the availability and sufficiency of suitable food. This is the factor that most worries those concerned with the parrots’ welfare – the BNT, the scientists and naturalists who helped to bring the species back from the edge of extinction, and organisations further afield such as Birds Caribbean. So it’s a question now of where they will find to feed; and beyond that, how they respond if they find their usual feeding haunts trashed.

SIGHTING REPORTS

The signs are that the parrots are now emerging and looking for food. With luck their presence will become more noticeable. This is an important moment for collecting stats. They will help research into the effect of Dorian on the population including the wellbeing of the birds, their flocking behaviour, and the locations they now find to their liking. The fact that parrots have been seen at BPS, the parrot hotspot, is encouraging.

If anyone sees or even hears parrots over the next couple of weeks I’d welcome a report either directly or indirectly. The most helpful details are date, time, location and approx numbers (1, pair, a few, lots). Beyond that, behaviour notes are of interest – feeding, chattering, hanging round, being unsettled and so on. A photo is always a bonus, even a phone one.

Do not doubt the resilience of these beautiful birds. Now that the threat of extinction has been removed through skilled conservation, management and predator control, they will win through. If you doubt it, just look at this image below. It shows a nest in the immediate aftermath of hurricane Irene, with its occupant safe and sound as the parents forage for food and parrot scientist Caroline nips in with her camera.

STICKING TOGETHER: BIRDS OF A FEATHER ON ABACO

STICKING TOGETHER: BIRDS OF A FEATHER

In times of trouble, of grief and of despair, humans have an instinct to rally round for the greater good. Right now, I am very conscious that on Abaco – and indeed Grand Bahama – there is little or no time or mental space for overmuch concern about the wildlife. I am safely distanced from the tragedies and dire misfortunes of the countless individuals, families and communities affected by Hurricane Dorian. In this post I simply offer some images of birds – all photographed on Abaco – that are bonded together as adults or adult and chick, as symbolic of the huge combined human efforts on Abaco to comfort, restore, and rebuild a shattered island.
