THE CONCH QUEST OF ABACO…

THE CONCH QUEST OF ABACO…

Conchs are gastropods. They are food. They are decoration (anyway, the shells are). For some, they are a living. And on Abaco they are everywhere – alive in the waters, and as shells scattered on  beaches or piled up outside restaurants. So the quest for conch is an easy one. There are fears of overfishing, however, and an active organisation The Bahamas National Conchservation Campaign exists to protect them. Another similar Bahamas organisation is Community Conch.conchs-at-sandy-point-1 We found a nice half-buried conch shell at Sandy Point. It was full of sand grains and tiny shells – mini gastropods and bivalves - that took some time to wash out of the spiralling internal structure. Here are some studies of the shell. IMG_2438IMG_2442IMG_2444IMG_2445IMG_2448IMG_5279IMG_5278 The damage to the shell above is the place where it has been bashed in to enable removal of the occupant. In order to do so, it is necessary to break the strong vacuum that would prevent extraction if you tried by the conventional route. Effectively the conch anchors itself to its shell and must be cut out. The best way to make the hole is with the spiral tip of another conch. This breaks the suction and enables you to prise out the occupant…

BMMRO COLLABORATES WITH NEW PARTNER, ATLANTIS BLUE PROJECT

The ATLANTIS BLUE PROJECT is managed by the Atlantis Blue Project Foundation, a private non-profit organization dedicated to the preservation and enhancement of global marine ecosystems through scientific research, education, and community outreach. BMMRO is excited to now be a part of this project and in turn has received two grants from the Atlantis Blue Project for 2014

Stranding Response to Support Conservation of Marine Mammals in the Bahamas 

Increasing capacity and available funds to respond rapidly to strandings in The Bahamas will increase our ability to determine cause of death and/or successful rehabilitation of marine mammals. At the first stranding workshop held in the Bahamas in 2008, the Honourable Lawrence Cartwright, Minister of Agriculture and Marine Resources officially opened the workshop stating “I believe the establishment of a Marine Mammal Stranding Network in The Bahamas will serve to promote the conservation of marine mammal species and their habitat by improving the rescue and humane care of stranded marine mammals, advancing stranding science, and increasing public awareness through education.” This funding will provide the resources to train veterinarians on how to work with stranded marine mammals as well as provide the resources to respond to strandings.

Field Research & Outreach to Support Conservation of Bahamas Marine Mammals

Cetaceans are long-lived, highly specialised animals with delayed reproduction and low fecundity, which makes them incapable of rapid adaptation and thus particularly vulnerable to anthropogenic impacts. BMMRO has compiled an unprecedented long-term dataset for the region, which has become increasingly valuable to inform about the baseline ecology of some odontocete species. This research will ensure that this important work continues to fill key gaps in our knowledge about the ecology of marine mammals. Additionally, we will increase awareness and build capacity amongst Bahamians, both of which will contribute to local conservation needs.

JANUARY SIGHTINGS

For Abaco, the excitement is the sperm whale seen just off the Rocky Point area. More generally for the northern Bahamas, in addition to the manatee Georgie (former temporary resident of Abaco) and others, there was a manatee reported on Eleuthera. It looks as though these gently creatures continue to find the area to their liking.

MARINE DEBRIS? NO THANKS! 10 FACTS FROM NOAA


Ten Things You Should Know About Marine Debris

monksealMonkseal being rescued from marine debris

Entangled-harbor-seal NOAA Marine Debris
Our waterways are littered with stuff that doesn’t belong in them. Plastic bags, cigarette butts, fishing nets, sunken vessels, glass bottles, abandoned crab traps…the list is endless. Some of this marine debris comes from human activity at sea, and some of it makes its way into our waterways from land.
While we know that marine debris is bad for the environment, harms wildlife, and threatens human health and navigation, there is much we don’t know. How much marine debris is in our environment? How long does it last? How harmful is it to natural resources or human health and safety? How long does it take to break down in the water? The NOAA Marine Debris Program is finding answers to these questions.

1. It doesn’t stay put

While a lot of debris sinks, much also floats. Once this marine debris enters the ocean, it moves via oceanic currents and atmospheric winds. Factors that affect currents and winds (for example, El Niño and seasonal changes) also affect the movement of marine debris in the ocean. Debris is often carried far from its origin, which makes it difficult to determine exactly where an item came from.

2. It comes in many forms

Marine debris comes in many forms, ranging from small plastic cigarette butts to 4,000-pound derelict fishing nets. Plastic bags, glass, metal, Styrofoam, tires, derelict fishing gear, and abandoned vessels are all examples of debris that often ends up in our waterways.img_0510_ss-1

3. It’s your problem, too

Marine debris is a problem for all of us. It affects everything from the environment to the economy; from fishing and navigation to human health and safety; from the tiniest coral polyps to giant blue whales.

4. NOAA is fighting this problem

The NOAA Marine Debris Program works in the U.S. and around the world to research, reduce, and prevent debris in our oceans and coastal waterways. Much of this work is done in partnership with other agencies, non-governmental organizations, academia, industry, and private businesses.The Marine Debris Research, Prevention, and Reduction Act, signed into law in 2006, formally created the Marine Debris Program. The Act directs NOAA to map, identify, measure impacts of, remove, and prevent marine debris.

img_0327

5. Some debris is being turned into energy

Abandoned and lost fishing gear is a big problem. It entangles and kills marine life and is a hazard to navigation. Based on a model program in Hawaii, the Fishing for Energy program was formed in 2008 to tackle this problem with creative new ideas. The program is a partnership between NOAA, Covanta Energy Corporation, National Fish and Wildlife Foundation, and Schnitzer Steel.This program offers the fishing community a no-cost way to dispose of old or derelict fishing gear. Once removed from the environment, the gear is transported to the nearest Covanta Energy-from-Waste facility. About one ton of derelict nets creates enough electricity to power one home for 25 days!

6. Marine debris can hurt or kill animals

Marine debris may be mistaken by some animals for food or eaten accidently. Often, larger items like nets, fishing line, and abandoned crab pots snare or trap animals. Entanglement can lead to injury, illness, suffocation, starvation, and even death. NOAA is working with many partners to tackle this problem by reducing and preventing marine debris in our oceans and waterways.

7. There’s a lot to learn about this problem

We know that marine debris is a big problem, but there’s much we need to learn. NOAA funds projects across the country and works with scientists and experts around the globe to better understand how marine debris moves, where it comes from, and how it affects the environment. This knowledge will help us find better ways to tackle the problem.

8. You can help us get the word out!

The NOAA Marine Debris Program offers a heap of creative products to get the word out about marine debris. Looking for brochures, posters, fact sheets, or guidebooks? We’ve got those. Like videos? We’ve got those, too. We even have a blog! You’ll find it all online.

9. This is a global problem.

Marine debris is a global problem that requires global solutions. NOAA experts work with scientists and organizations around the world to share lessons learned, discover what programs work best, and map out future strategies to fight this problem.

img_04761

10. Small steps lead to big results

Fighting the marine debris problem begins at home.

  • - Try to cut back on the amount of trash you produce.
  • - Opt for reusable items instead of single-use products.
  • - Recycle as much of your trash as you can.
  • - Join local efforts to pick up trash.
  • - Keep streets, sidewalks, parking lots, and storm drains free of trash—they can empty into our oceans and waterways.

ABACO: AN IMPORTANT BIRDING AREA IN THE BAHAMAS

The Bahamas National Trust BNT is one of several organisations in the Bahamas responsible for conservation across the widely scattered islands of the Bahamas. One of its tasks is to look after the birds and their habitat, and from time to time the Trust publishes articles about their work. The Abaco-related material below is taken from a much longer article by Predensa Moore and Lynn Gape that covers the whole area, and concerns the importance of Abaco as a prime Bird Area. This applies in particular to Little Abaco and the Northern Cays; and to the large area of South Abaco that incorporates the National Park. The bird images used show some Abaco speciality birds mentioned by the BNT in their material.

EARLY BIRDS ON ABACO: CHARLES CORY’S EXPEDITIONS 1891


00179p1

EARLY BIRDS ON ABACO: CHARLES CORY’S EXPEDITIONS 1891

Before the explorations of the american ornithologist Charles Cory towards the end of the c19, there had been few if any serious attempts to record the birds of the Bahama Islands, especially the sparsely populated ones such as Abaco. The english naturalist Mark Catesby had published his  wonderful The Natural History of Carolina, Florida and the Bahama Islands as early as 1754, which of course included some birds, but it was far from avian-specific. During the 1880s, Cory forsook the golf course (his other passion – he even competed in the 1904 Olympics but, as it is intriguingly put, “…did not finish…”) to concentrate on birds. He commenced his research for his List of the Birds of the West Indies, published in 1886. The scope was wide, including Antilles, Jamaica, Cuba, Hispaniola and the Bahamas. The book simply listed birds by family, giving the bird names in Latin, and the locations where they were found. It’s scarcely an enticing read, and the ‘print on demand’ copy I obtained for about $15 is frankly horrid.00199p1

In 1891, Cory and his colleague Mr C.L. Winch paid more specific attention to the Bahamas, visiting several islands, taking specimens and recording their findings. Cory subsequently published these in the ornithological journal of record, The Auk, established in 1884 as a quarterly peer-reviewed scientific journal and the official publication of the American Ornithologists’ Union (AOU).  I’m not clear whether Cory actually accompanied Winch throughout the voyages, or whether they covered the islands separately. In any event, the first visit to Abaco took place in March 1891, when Mr Winch took specimens and recorded the species he encountered.00161p1

To save you the bother of taxing your brain with Latin  taxonomies (in some cases out-of-date), the species recorded are shown below. Every one of these species might be seen during a March visit nowadays.

In June they were back on Abaco; or at least, Mr Winch had returned. This time, the list of species was somewhat different, as one might expect in the summer season. It contains one particular curiosity: the Bahama Oriole. This fine bird was sadly extirpated from Abaco in the 1990s, and may now only be found on Andros. There are reckoned to be only about 300 left, so the species is on the brink of extinction.Bahama Oriole.jpg (Wiki)

NEST PROTECTION: WILSON’S PLOVERS ON ABACO (2)

NEST PROTECTION: WILSON’S PLOVERS ON ABACO (2)

This is the second of three vaguely planned posts about these delightful shore birds. They aren’t rare but they are approachable and fun to watch. During the nesting and hatching season, there may even be some gorgeous chicks on a beach near you (a phrase I never thought I’d find myself using). PART ONE identified the typical male and female adults found on the Delphi beach almost any day. 

Nettie's Point, Abaco - Trucks & Skiffs

This post is about nest protection. Not the ingenious methods of  the birds themselves, that will come next time. This is a story of protection by humans. The photograph above shows Nettie’s Point, one of the launching points for bonefishing skiffs being taken out to the Marls, a vast area of sea, low sand banks and mangroves where the fish are found. You hope. The skiffs gain access to open sea via an artificial channel carved out of rock. The early morning trip along it is one of the most exciting part of a fisherman’s day, as he or she sets out with a clean score sheet, a rod and a box of flies. And a cooler box with some food and maybe a Kalik beer or three.

Nettie's Point, Abaco - the cut to the sea

This June, a pair of plovers decided to locate their nesting ‘scrape’ right in the middle of the cleared area where the trucks normally turn. This was by no means a wise home-planning decision, and they might well have found themselves being promptly relocated. Or (worst case scenario) ending up under a large Toyota. But not a bit of it. Instead, these small birds were looked after by the guides like this: Nettie's Point, Abaco - Plover's nest protection

A makeshift castle was built all round the nest to protect it from any inadvertent truck-related tragedies. Meanwhile the male plover stood guard outside the castle, amiably watching the human activities. Nettie's Point, Abaco - Male Wilson's Plover guards nest

I kept my distance but in fact he was quite unperturbed, perhaps sensing that we were not a threat. He still kept a beady eye on the proceedings, though.Nettie's Point, Abaco - male Wilson's Plover guards a nest

Meanwhile, what of the wooden enclosure itself? At first glance, there didn’t look much to report. However, if you look in the centre of the picture, you’ll see the female peeping out from the nest.Nettie's Point, Abaco - Nest protection 2

I very slowly moved nearer, prepared to stop if the male became agitated, or if the female shifted her position. Both seemed quite relaxed, so I took a couple of shots and walked away to leave the birds in peace. Then I went fishing.Nettie's Point, Abaco - Female Wilson's Plover on NestNettie's Point, Abaco - Mrs Wilson's Plover on the nest

As a postscript, Nettie’s Point is the location of a remarkable geographical phenomenon, possibly the result of the cutting of the channel. Along one part of the cut, for about 30 feet, the water level sinks alarming in the middle, while remaining normal at each side. Then it levels out again. This remarkable mid-stream aquatic depression is quite disconcerting to motor through on a skiff, though eventually one gets used to it. Nettie's Point, Abaco - channel water phenomenon(Note: not every fact in this post is 100% true.

3 MONTHS ON ABACO WITH THE BMMRO: AN INTERN’S STORY

My name is Jack Lucas and I am Marine Biology Student at Plymouth University in the UK. I came to the Bahamas Marine Mammal Research Organisation on Abaco in July 2013 for a 3 month internship, which has been an amazing experience from start to finish. Heres a summary of my summer spent at BMMRO.

Sperm Whale Fluking

I arrived at the start of July and was fortunate enough with my timing to be part of an assembled crew of scientists from all over the world coming together to start work on what was to be this summers main project; collecting faecal samples from Blainville’s beaked whales to assess stress hormones produced. This team included Dr Roz Rolland and Dr Scott Kraus from New England Aquarium, who are collaborating with BMMRO for the work, and the samples will be analysed back at their lab in the US. Also along for the ride was Roxy Corbett; a whale observer and field researcher from the US, and Dr Stephanie King; a acoustician from the Sea Mammal Research Unit in Scotland. The first day after arriving it was straight out on the boat to search for these elusive creatures and the beginning of a crash course in how to collect and store the faecal samples when we found them. For the first week the work was a mix of boat work when the weather permitted and practicing poop collection using custom-made fine-mesh nets and coffee grounds (as close to the real thing as we were willing to try!), as well as clearing out BMMRO’s garage and, under the direction of foreman Scott, the construction from scratch of a lab to prepare samples for storage.

An example of the use of coffee grounds to practise whale poop-scoop technique269RH note: NOT Jack’s arms / snappy diving suit…

Unfortunately, despite days of poop collection practice and endless hours searching for the whales at sea, the original poop team never got a chance to employ these by now highly developed skills or to see the lab being used, as the weather was so windy we barely encountered the animals let alone spent long enough with them to collect any samples. 

Despite the lack of beaked whales, we did encounter loads of marine mammals in the first few weeks, from sperm whales to three different species of dolphin; including the little-seen and even less-studied rough-toothed dolphin.

Rough-toothed Dolphin

After discussion with Charlotte and Di about a possible project for me to complete during my stay, it was to be this species that I would focus on and in between the usual office jobs it was my task to sort through the photos from 20 rough toothed encounters in the Bahamas since 1995 and create a catalogue of individuals. This initial task consisted of careful inspection, comparison and sorting of what turned out to be over 5000 photos, into an organised catalogue of 167 separate and distinctive individuals. Despite the hours of endless staring at fins, it was very rewarding as there were 13 resighted individuals found (we were not necessarily expecting any!) which suggests long-term site fidelity and association of these animals, in addition to year round use of the Grand Bahama Canyon. Even more rewarding; the results of this work have recently been submitted for a poster display at an Odontocete workshop in New Zealand this December and I am also writing up the results in a formal scientific paper, with the hopeful goal of publishing a note in a peer-review journal. 

 Scott, Jack, Stephanie and Di in the new lab at Sandy Point

Around a month in I was lucky enough to be sent by Di and Charlotte to Great Harbour Cay on the nearby Berry Islands to work with the manatees there, in particular Georgie; a recently released juvenile whose status is being carefully monitored after her rehabilitation at Atlantis’ Dolphin Cay following health problems. The work here for a week under the guidance of Kendria; a Bahamian contracted by BMMRO to monitor the manatees on the Berry Islands, consisted of tracking Georgie using a satellite tag attached to a belt around her tail. Once located, we logged her position and made any notes on her health and behaviour aswell as the other manatees that were often found with her (there are currently 6 located on Great Harbour Cay). Two days in her tag was found unattached at a locals dock (it has a weak-link incase of entanglement) and we had to locate her using underwater hydrophones to detect her belt. Once found, I had the rare opportunity of entering the water with her in order to re-attach a new tag to her belt; it was amazing and one of the best encounters I have had with any animal! It is impossible not to love these amiable and gentle creatures, especially when you observe their infamous ‘hugs’ in person! 

Georgie the Manatee

For more about Georgie’s re-release in the Berry Is. after her earlier shenanigans on Abaco, see HERE

After returning from the Berry Islands (and incidentally missing the first two poop collections of the season made by Charlotte!) it was back to hunting for the elusive beaked whales around South Abaco. During my time I had the chance to work with several interns coming to BMMRO including local marine-enthusiasts Tristan and AJ, and Courtney Cox from Florida. Oscar Ward from the UK also joined the team as Charlotte left for Scotland to complete her PhD, and was on hand during the poop-collection and other little excursions. In wasn’t until the last month of my time here that we managed to get close enough to the whales for me to get in the water and be towed alongside in the hope of seeing one defecate. One amazing morning two whales surfaced right off the bow of the boat and what resulted was again, one of the most amazing moments; swimming just a couple of feet away from an animal only a handful of people in the world have seen underwater. After nearly two months with no samples, the two weeks that followed were a flurry of boat days, poop-collection and whale watching; with a total of 7 samples collecting from beaked whales (5 in one day!!) and another 3 from sperm whales. This was the best possible end to my time here and I finally got a chance to use the much-practiced poop collection techniques. The samples included a number of squid beaks, and in one very deep dive collection a mass of parasitic worms and a weird cephalopod-type animal! We also got a chance in the last few weeks to test-run a new addition to the fleet, that included a dive compressor.

Ready to collect some poop…

Finally my time in the Bahamas had to come to an end, and I had to return home. The last 3 months has flown by and has been one of the most enjoyable and most importantly educational periods of my life and I cannot thank Di and Charlotte enough for making it all possible. The day-to-day boat runs, office work, equipment maintenance and station chores has given me a good insight into all aspects of field research. It was my first taste of life as a marine mammal scientist, and it has made me even more determined to pursue a career in this field; a perfect stepping stone from which to move forward. In addition my work with BMMRO (and what must of been a brilliant reference from the girls!) made it possible to secure a highly competitive internship in the Farallon Islands this winter tagging elephant seals amongst other work! I cannot wait to continue working in this field and finish writing up the results of my project here, and hope I have the chance to come to Abaco again to work with these amazing people and animals!Sperm Whale supplier of poop BMMRO

BMMRO would like to thank Jack for all his help during the summer, and all our interns for their assistance! To our sponsors, Friends of the Environment, Disney Animal Programs and Environmental Initiatives and Rotary of Abaco, we thank you for your continued support.

ABACO PARROTS TO CELEBRATE A MODEST LANDMARK

‘Rolling Harbour: The Blog’ had humble beginnings – a dodgy structure built on foundations formed of an unpromising mix of ignorance and incompetence. Gradually it has come together, to the extent that it has just passed the 125,000 visits mark. Abaco is a small and uncrowded island, so the audience demographic [to use biz-speak] isn’t large. However the wildlife, scenery and lifestyle have turned out to have a wider appeal. 1/8 of a million people (or perhaps 1 crazy punter with repetitive strain injury from checking in unhealthily often) deserve a few of Abaco’s unique parrots in return.

GEORGIE THE (FORMER) ABACO MANATEE RETURNS TO THE BERRY IS.


Georgie the Manatee, Hope Town, Abaco (© Stafford Patterson) 1

GEORGIE THE (FORMER) ABACO MANATEE RETURNS TO THE BERRY IS.

Last year I posted about Georgie, the young manatee that made Abaco her home for several months. Georgie was born in Spanish Wells. She and her mother Rita travelled to Nassau Harbour, where in April 2012 they were rescued from the multiple shipping hazards and  released in Great Harbour Cay, Berry Is. Both were equipped with tags to monitor their movements. In June, the newly-weaned Georgie embarked on a big solo adventure by swimming to Abaco. Her tracking device showed that she called in at the Marls, before continuing right round the top of Abaco and down the east side, calling in at various Cays on the way. In all, her journey was some 200 miles long. She eventually settled down in the Cherokee and Casuarina area, and in a modest way became a lettuce-chomping celebrity.  DANA & TRISH FEEDING GEORGIE (2)

Concern was raised about her general appearance and the decision was made… to conduct a field health assessment and relocate her to the Atlantis Marine Mammal Rescue Center. “recap1

“Georgie underwent a series of general health evaluations and was fed approximately 75 pounds of lettuce each day. She gained more than 200 pounds during the course of her care and weighed 569 pounds upon her recent release”. recap4

“We are pleased to announce that Georgie has now been released once more to Great Harbour Cay in the Berry Islands after a successful rehabilitation at Atlantis’ Dolphin Cay. She was successfully released on Wednesday 14th August by the Atlantis Animal Rescue Team from the Atlantis Dolphin Cay Marine Mammal Rescue Center, with the help of the Bahamas Marine Mammal Research Organisation (BMMRO). She has a satellite tag attached to her which will help post-release monitoring, currently being conducted by representatives from BMMRO and Dolphin Cay.”

“The first 3 weeks of Georgie’s release  showed her venturing on longer and longer journeys, with the blue circles showing her first weeks’ movements, the red her second, and finally the yellow circles her locations up to Saturday. She is doing very well and often seen with the other manatees in the area.”

CONCH SHELLS & CONCHUPISCENCE ON ABACO

Most conchs encountered in daily life are lying peacefully on the beach; or are artfully displayed; or are found in conch heaps (often in the vicinity of restaurants) like the ones below at Sandy Point. Conchs at Sandy Point Abaco 2Conchs at Sandy Point Abaco 4

It’s easy to forget that these shells are more than just a garden adornment, or pretty containers for a ubiquitous Caribbean food. Under the sea, and not very far at that, are living creatures going about their daily lives.Conch ©Melinda Riger @G B ScubaConch ©Melinda Riger @ GB Scuba

And that includes reproducing. This sounds as if it might be a cumbersome process, but (like porcupines) they seem to manage. Here is a pair preparing to mate. The male behind is presumably about to… well never mind. I’ve never seen the process, so it’s a case of using imagination. Or just accepting that, whatever it is that they do, it works.

‘FAMILIAR FECES’: CETACEAN POOP-SCOOPING BY SPECIES

UPDATE I name-checked BMMRO intern Oscar Ward’s blog below. Now he’s been out on the ocean on ‘poop patrol’. You can read Oscar’s account of his experiences HERE

Among the many pleasures for cetacean research scientists must be the joy of whale poop collection. Followed by close inspection and analysis. The Bahamas  Marine Mammal Research Organisation BMMRO conducts research expeditions, in conjunction with such organisations as the New England Aquarium NEAQ and Friends of the Environment FOTE, in Abaco waters and further afield in the Bahamas. The attention this year has been on beaked whale feces, though available sperm whale feces are not to be sniffed at. Images and info below are courtesy of the organisations mentioned above, with thanks for use permission

A researcher working with BMMRO demonstrates feces collection using coffee grounds. She collects the coffee granules in her net and places the entire sample into a ziplock bag, ready to hand to the boat for processing 269

The purpose of feces collection is to look at the stress and reproductive hormones of the whales and to gather a baseline for these animals with which to compare other populations that are under threat3

That’s enough on the topic for now. Later in the month there will be some great dolphin pictures to enjoy. Below is the BMMRO sightings chart for July, which I forgot to publish sooner.

Finally, a young UK friend of ours, Oscar Ward, has recently won his place to study marine biology at university next Autumn. He has just arrived on Abaco to start an internship with the BMMRO at Sandy Point. He will then be moving to Friends of the Environment in MH. He has set up an excellent blog to record his experiences, with his first Abaco post going up today, I notice.

BANANAQUIT BABIES ON ABACO: AWWWWWW…SOME BIRDS

I’m not generally into whimsy and such stuff BUT… I can’t get enough of small bananaquits (Coereba flaveola). I’ve featured them before HERE and HERE AGAIN, but then I see another one, take some photos, and awwwwww – look at its little fluffy feathers… and its tiny sharp claws! The two shown below are summer babies. They aren’t really babies, though, are they? Teenagers, more like. Like many Abaco birds – especially the parrots – they are keen on the fruit of the Gumbo Limbo tree Bursera simaruba shown here. They also love flowers, piecing the base with their beaks to get at the nectar. They are quite as happy on a feeder – or indeed sipping sugar water from a hummingbird feeder, living up to their nickname ‘sugar bird’.

This second bird is a bit older, and has developed some smart citrus lemon shoulder flashes. Bananaquits have many regional variations throughout the caribbean and beyond. These birds are, or were, generally lumped in with the tanager species. They have an official classification of ‘uncertain placement’ in the taxonomic scheme for now, while their exact status is debated. Not that anyone watching them worries about that sort of technicality.Bananaquit (juv) Abaco, Bahamas 6Bananaquit (juv) Abaco, Bahamas 5

UNDERWATER REEF GARDENS IN THE BAHAMAS (2): CORALS

This is part 2 of a series that started out HERE with a selection of anemones, basket stars and Christmas tree worms. The images below show a wide variety of corals. In among them are also sponges and anemones. These photos are evidence of a healthy reef environment in the waters of the northern Bahamas. Abaco’s coral reef is the third largest barrier reef in the world (yes, I hear you – the Great Barrier… And the second is???), providing wonderful and accessible diving / snorkelling opportunities. However, monitoring shows that the incidence of coral bleaching and disease is increasing in the Bahamas, as elsewhere in the world.  It’s a sobering thought that your grandchildren may never swim in an environment with any of the living corals shown below…

ABACO’S RAREST VISITOR: MEET ALBERT ROSS… THE ALBATROSS


ABACO’S RAREST VISITOR: MEET ALBERT ROSS… THE ALBATROSS

I can find no record for the sighting of an albatross in the waters around Abaco. Nor for anywhere else in the Bahamas for that matter. It must have come as some surprise to the BMMRO team out at sea on their research vessel off Sandy Point to see a large and unusual seabird bobbing tranquilly on the water. A black-browed albatross Thalassarche melanophrys. Diane Claridge managed to get a great shot of it and I’m really pleased to be able to use it here.

This bird was way out of the normal range for the species. They are birds of the southern oceans, breeding in colonies on such islands as the Falklands, South Georgia and Macquarie Island. As far as I can make out, they have no business to be north of the equator at all.

SIGHTING A BLACK-BROWED ALBATROSS: A REPORT

During a three-hour survey for whales off Sandy Point, Abaco on Sunday, July 21st scientists from the Bahamas Marine Mammal Research Organisation had an exceptional sighting. Dr Diane Claridge, the group’s Executive Director recalls details of the sighting:

“We were drifting waiting for a beaked whale to resurface when our intern Tristan Albury pointed towards a white object floating in the distance and asked what it was. We decided that it was a piece of trash, unfortunately a common sighting, and continued to focus our search for the whale. A half hour later, we still had not re-sighted the whale and believed that it may have gone down on one of its one-hour long feeding dives. So with time to kill and the “trash” still in sight, we had another look with binoculars. We realised immediately that it was a very large bird and slowly motored towards it for a closer look. I began taking photographs of it because we already knew it was unusual and we wanted to be sure to identify the species. As we got closer, Roxy Corbett, a visiting scientist and avid birder exclaimed that it was an albatross! I couldn’t believe it. We were able to approach within 100 feet at which point it swam towards us providing an opportunity for us to document its body condition; it appeared healthy with no obvious signs of distress.

Later when back ashore, we compared our photographs with those available online and learned that it was a juvenile Black-browed albatross, an endangered bird with a 7-foot wing span known from subtropical to polar regions of the southern hemisphere! As far as I know this species has never been recorded previously in the tropical North Atlantic. I have seen albatross during whale surveys in Alaska but never dreamed that I’d ever see one in The Bahamas. Although we are thrilled by the rarity of this sighting, the outcome for a bird so far out of its normal range is not usually good. However, there are two Black-browed albatross that strayed into the North Atlantic previously that have taken up long-term residence in Scotland and the Faroe Islands so who knows where this one may end up. Sunday afternoon was indeed exceptional: in addition to this remarkable sighting, we also saw 4 different species of whales and dolphins, all within 5 miles of Sandy Point.”

These are huge strong birds, with a massive wingspan. I wondered what they might sound like – it’s like this… (Credit: Xeno-Canto & recordist Sofia Wasylyk)

SOUTHERN STINGRAYS: KEEPING AN EYE ON YOU


Stingray Eye ©Melinda Riger @GBS

SOUTHERN STINGRAYS: KEEPING AN EYE ON YOU

The SOUTHERN STINGRAY Dasyatis americana is a ‘whiptail stingray’ found in the Western Atlantic Ocean. Their habitat and personal habits – feeding and mating – are similar to those of the YELLOW STINGRAY. They live on the seabed, where they feed on small crustaceans, molluscs and fish. They expose their prey by flapping their ‘wings’ (= pectoral fins) to disturb the sand

Southern Stingray ©Melinda Riger @ GB Scuba

You want to avoid treading on one of these if possible. Their tails have a serrated barb covered in venomous mucous, used for self-defence. These spines are not fatal to humans, but if you step on one it may be an experience in extreme pain to tell your grandchildren about. Southern Stingray

Luckily they are likely to see you long before you notice them, and to swim away from your approachSouthern Stingray ©Melinda Riga @ GB Scuba

IUCN LISTING: ‘DATA DEFICIENT’

Surprisingly, the ‘at risk’ status of the Southern Stingray is not known. However, as with other marine species that humans like to befriend in the wild for the perceived benefit of both parties, there are parts of the Caribbean where stingray swims involve rather more than merely swimming with and enjoying the rays in their own environment. There is organised hand-feeding with cut-up fish, even general fondling and cuddling, that can make these wild creatures seem ‘tame’. There is growing concern that such close dependent interactions with humans is not a good thing, at least for the stingrays.

From time to time I post individual items on the CONSERVATION page. This comprises an assortment of articles, photos, videos and graphics with an eco-message relevant to Abaco and its waters. They accumulate gradually, and occasionally it is good to post a selection for consideration. What is the most frequently found item of detritus on a beach? Is it ok to eat striped bass? How many uses does a coconut have? How quickly does the invasive lionfish population spread? What is Fish Pharm? How many years does it take for an aluminium can to decompose? These and many other questions are answered below.

NOAA MARINE DEBRIS PROGRAM

Keepin’ the Sea Free of Debris!

ICC volunteers clean 10 million lbs of trash from our coasts
May 16, 2013 by NOAA Marine Debris Program

By: Dianna Parker

One rubber chicken, 117 mattresses, 4,159 candles, and 689,274 utensils. What do all of these things have in common?

They’re all marine debris collected last September at the Ocean Conservancy’s 2012 International Coastal Cleanup®, sponsored in part by the NOAA Marine Debris Program.The numbers are in: more than 550,000 volunteers came together to collect 10 million pounds of marine debris.  In the United States, volunteers found enough bottles that, when stacked end to end, equal the height of 1,000 Empire State Buildings. That’s a lot of trash on our beaches and in our waterways!This litter is threatening our marine environment, economy, and health, and the problem will only get worse unless we change the way we consume and dispose of products. There are solutions, and we can prevent litter from ending up in the ocean.So here’s a challenge: the next time you use a throw-away item: a bag, bottle, or utensil, answer the question, “Where it’s going?” How will you keep your items from becoming litter in our oceans, rivers, and streams? Head to Ocean Conservancy’s data release page for some neat infographics on last year’s trash haul. Here are the top 10 types volunteers found this year

IUCN CUBAN PARROT RED LIST RANGE MAP FOR AT RISK SPECIES
I have annotated this IUCN map of the Cuban Parrot population range. It’s worth noting that the Bahamian subspecies is now found only as a breeding population on Abaco and Inagua, being defunct on all other islands since the mid-c20. Of these populations, only the Abaco parrot breeds underground, a unique feature among the whole species.
I am puzzled by the suggestion of an ‘extant (resident)’ population on the Bimini Is. That would suggest that they breed there. I don’t know the date of the map, but I have checked with the Avibase bird database, and the Cuban parrot is indeed included in the list of Bimini birds. I’ve put a query on the map because I don’t know what the position is in 2012.

FRIENDS OF THE ENVIRONMENT (ABACO)
This conservation organisation has recently completely redesigned its website (click logo above), and presents comprehensive and easily navigated information about a myriad aspects of conservation on Abaco and its fragile ecology. The fragility is mostly directly or indirectly caused by mankind (a broad statement, I know, but it’s an arguable stance), so it’s worth checking out the measures that are being undertaken to preserve the natural resources of the island and its cays. Below is a post about one feature highlighted on the FotE site that I am particularly interested in. Overall all the new website is definitely one for any Abaconian (or, like me, regular visitor) to study. If you want to contribute your support (either generally or to a specific cause) go to the FotE website (click logo) or visit the Rolling Harbour wildlife charity page HERE

THE EFFECT OF RISING SEA LEVELS IN THE CARIBBEAN

This map has been posted by the SCSCB, with the very interesting and definitely worrying text “The map shows projected impacts of a 2 meter sea level rise in the Caribbean. The orange is the impact of 2 meters, while the yellow is the 25 meter line. The last time the ice caps melted the sea rose between 18 and 25 meters. The most conservative estimates indicate a 1-meter rise by the end of the century (concurrent with a 2 degree C rise in temperature). From the position of planning, I am curious about the estimates being used by Caribbean resource managers in their long-range planning. For example, what percentage of Caribbean seabirds nest below 2 meters…”

BAHAMAS NATIONAL TRUST PRESS RELEASE JUNE 2012

ABACO PARROT POPULATION ON THE RISE

The Bahamas National Trust  in conjunction with Dr. Frank Riviera and Caroline Stahala recently conducted an intensive survey of the Bahama Parrot on Abaco Population surveys conducted in 2002 resulted in estimates of the Abaco parrot population of about 2,500 parrots with similar values in the following years. This year Dr. Frank Rivera and Caroline Stahala, who took part in the initial surveys, helped by  BNT wardens and volunteers, conducted a 10 year follow up survey to determine the change in the Abaco parrot population since management began. The results indicate that the Abaco parrot population has increased since the BNT’s management efforts were implemented with a new estimate of just over 4,000 parrots on Abaco. The BNT has been concerned about the Bahama Parrot Population since the 1980’s. Studies indicated that the major threat to the parrots were feral cats who cause serious problems to the parrots during the nesting season by entering the underground nesting cavities and killing the breeding adults and chicks. The BNT implemented an intensive predator control effort in 2009 throughout the parrot nesting area culminating in the hiring of Marcus Davis as Deputy Park whose primary responsibility is to oversee the predator control program. During the breeding seasons the BNT has seen a decrease in the number of breeding parrots killed and nest success increase. The question, though, remained whether this effort would translate into an increase in the Abaco parrot population size. Survey results indicated that predator control has led to an increase in nest success.  In addition, the Abaco parrots have weathered several hurricanes (Frances, Jean and Irene) over the last 10 years and still appear to show  a population increase. Hopefully with continued management efforts a healthy and viable  endemic parrot population on Abaco will continue to thrive. According to David Knowles, BNT Director of Parks “This gives us hope that with continued management efforts we can continue to have a healthy and viable endemic parrot population on Abaco.”

The research, tagging and monitoring programs pay dividends in conservation and species preservation terms… but then along comes a brutal reminder, way out in the pristine ocean, of the far-reaching extent of man’s reckless damage of the planet and the creatures in it.
