ENDANGERED SPECIES DAY: ONE LITTLE REASON WHY IT MATTERS…


Piping Plover Chick ©Melissa Groo PhotographyI had been going to post a selection of bird photos to mark Endangered Species Day today. I’d begun to plan the details – the birds to use, the captions for each and so on. Then I saw one photograph that is so charming and yet so poignant that I realised that adding further images would be superfluous. This tiny piping plover chick is a potent symbol of the vulnerability of all threatened species.

This shot was taken by award-winning and renowned wildlife photographer Melissa Groo. If you want to see the most wonderful and varied wildlife photography that you could ever imagine, please go to Melissa’s website and prepare to be amazed. You will find it HERE

I have posted several times about the endangered piping plovers, many of which overwinter in the northern Bahamas generally, Abaco particularly, and the Delphi Club beach specifically. There are believed to be fewer than 8000 individual birds on earth, and their little world of the shoreline is threatened at both ends of their migration, as well as at their rest ‘stopovers’ en route in either direction. Conservation programs at each end of the range are proving effective at preserving the plovers’ habitat, and the population does seem to have increased slightly. Each chick protected represents a small triumph for conservation.

AUDUBON’S ‘PRIORITY BIRDS’ ON ABACO: 21 SPECIES TO TREASURE


Black-necked stilt AH IMG_1462 copy - Version 2

AUDUBON’S ‘PRIORITY BIRDS’

PRIORITY BIRDS ON ABACO

Of the total of 49 species listed by Audubon, an astonishing 31 are recorded for Abaco. Such a statistic underlines the importance of the island and its cays as a major birding location with habitat suitable for these ‘Priority Birds’ . Some of them birds may be rare ‘vagrants’, or occasional ‘transient’ visitors but all are considered threatened or vulnerable. I have marked in red the ones that may easily or with reasonable diligence and luck be found on Abaco. These are either Permanent Resident (PR) species; or Migratory species resident in Winter (WR) or Summer (SR); or TRansients that are seen annually or at least are regularly reported. For all practical bird-spotting purposes, the remainder can be set aside, and with no disrespect to them I have reduced their image & entry sizes… That leaves 21 species selected by Audubon for special protection that may be quite readily found on Abaco – and that will be adversely affected by significant habitat change. Birds to treasure, in fact.

BOTTLENOSE DOLPHINS IN ABACO WATERS (2): MOTHER & CALF


Dolphin Mother & Calf, Sandy Point, Abaco, Bahamas 12

Sometimes things happen that completely take my breath away. Here is one of those moments, from our recent trip with Charlotte and Diane in the BMMRO research boat. As we returned from whale-watching to base in Sandy Point and moved from the deep dark ocean to the bright blue shallows, we encountered a group of bottlenose dolphins. You can see my recent post featuring some of the adults HERE. That was exciting enough, as they played around the boat. Then another participant appeared… 

 Notice the dark area behind the adult dolphin… Dolphin Mother & Calf, Sandy Point, Abaco, Bahamas

…which soon separated into a small dark splashing creature with its own fin cutting the waves…Dolphin Mother & Calf, Sandy Point, Abaco, Bahamas

The sharp line between the light and the dark sea is where the sandy shallows abruptly give way to the deep waters of the Grand Bahama Canyon, a massive trench up to 2.5 miles deep with almost vertical cliff walls to the depths in some places

And finally the pair moved away.

Or anyway a very happy Tourist. The choice is yours. Would you like fries with that?Dolphin Mother & Calf, Sandy Point, Abaco, Bahamas

And looking out to sea from the cheerful place that is Castaway Cay, I wonder if a small child was wondering “Ok, love Mickey and his Friends – but I’d also really love to see a wild dolphin swimming free…

ABACO, HERE WE COME – READY OR NOT…

The seats are chosen, the online check-in done, the die is cast… Mr and Mrs Harbour are on their way in the BA cattle truck. Laptops are to be abandoned for the duration, but I intend to post occasional things of interest by iPhone – a Kirtland’s warbler sighting, maybe (I wish!) or a fish that has stupidly managed to impale itself on my hook perhaps. Normal blogging service, if there is such a thing round here, will be resumed in due course…

“THE BIRDS OF ABACO”

The book was launched at the Delphi Club exactly one year ago. We have been really delighted by the huge interest in it and the enthusiasm for it shown by so many people – residents, migratory residents and transients. There are still copies available*. If anyone would like a signed copy while we are at Delphi, I’m sure that can be arranged. I shall bring my special signing pen (it doesn’t smudge!) just in case…

It’s possible – by which I mean highly likely, of course – that perceived ‘downtime’ on Abaco will in fact be quite busy. Fishing. Birding. Beaching. Pooling. Talking. Drinking. Eating. Sleeping. So apologies in advance if I’m not so responsive to comments, Facebook stuff and general soshul meeja matters. No offence meant and I hope none taken – I’ll try to keep up with it or play catch up in due course. Anyway, for those who kindly stick with Rolling Harbour or drop in occasionally, much appreciated…

BAHAMAS MANATEES: GINA’S GOOD NEWS FOR 2015

BAHAMAS MANATEES: GINA’S GOOD NEWS FOR 2015

Last year held hopes of a joyous reunion – and indeed union – in Abaco waters between young manatees Randy and Georgie. He had taken the trip from the Berry Is., around the top of Abaco and down the east coast as far at Little Harbour. She lives in Cherokee. Tantalisingly close. But then Randy retraced his steps as far as Gorda Cay and hopes for the production of Abaco’s first manatee calf (at least, in living / recorded memory) turned to seagrass mulch. The poignant story and some great manatee close-up photos (including a ‘selfie’ of sorts on a Go-Pro) can be found HERE

But manatees do breed elsewhere in the Bahamas, in particular the Berry Is. They also seem to favour the north end of Eleuthera, and have been seen on Andros and NP. True, the absence of significant freshwater sources in the Bahamas – an essential part of their diet –  doesn’t make for an ideal habitat, but manatees do pair off and Bahamas calves are born. In summer 2012, there were four resident West Indian Manatees (Trichechus manatus) living in Great Harbour Cay, Berry Is. The adult female, Gina, had been there for 3 years – she originated from Florida. She had reportedly had 3 or 4 calves and was caring for her latest, a female calf called JJ, born in the late winter of 2011.

Adult female manatees are sexually mature at 6-10 years of age and have a gestation period of up to 13 months. The first two years of a calf’s life is spent with its mother. During this time they are taught where to find food, fresh water, warmth and shelter. Generally, after two years the calf is weaned and separates from its mother (see header image of Gina and JJ during that process)

Now there is more good news for Gina, who has been under regular observation by the BMMRO. At the turn of the year, Gina was re-tagged in Harbour Island, Eleuthera. As reported,  “she looks well, was very calm and is very pregnant… If the tag comes off and is found, please call the number on the tag to let us know – we are now monitoring her movements via the internet”.

I will post any further news about Gina as it arises. Meanwhile, for more information about West Indian manatees, you can visit the MANATEE PAGE. There are several links there to specific manatee stories, especially about Rita and her adventurous daughter GEORGIE, Abaco’s current favourite (indeed, only) resident manatee… Both Links need an update, I notice –  they don’t cover Georgie’s subsequent return to Abaco and her contented settling down again in Cherokee where she seems happy as a… sirenian.

ABACO’S FOUR PROTECTED AREAS: THE PROPOSALS

ABACO’S FOUR PROTECTED AREAS: THE PROPOSALS

The latest version of the 40TH ANNIVERSARY OF THE BAHAMAS PROPOSAL FOR THE EXPANSION OF THE PROTECTED AREA SYSTEM OF THE COMMONWEALTH OF THE BAHAMAS has been published. It is a joint proposal by the Bahamas Government, The Nature Conservancy and the Bahamas National Trust. The breadth of the scheme is very ambitious, affecting all the principal Bahama Islands. To understand the objectives and scope of the project, you can see the whole 34-page project by clicking BAHAMAS PROPOSED PROTECTED AREAS 2014 It is in pdf format, so you should be able to save it if you wish to.

Many people will be familiar with the proposals as they affect Abaco. However since the latest version appears to be a final draft, I thought it might be helpful to show the 4 proposed areas of protection and conservation in their present form. These are, in summary:

  1. THE ABACO MARLS NATIONAL RESERVE A vast area of nearly 200,000 acres (300 square miles) of mangrove flats, sandbanks, creeks and wetland habitat
  2. EAST ABACO CREEKS NATIONAL PARK 13,000 acres (20 square miles) of wetland habitat that provides a vital wildlife nursery, and includes blue holes, creeks and a significant area for recreational activities (though Pete’s Pub at Little Harbour may be just outside the zone…)
  3. CROSS HARBOUR PROTECTED AREA 14,000 acres (21 square miles) in South West Abaco, a crucial breeding area for a number of species,including bonefish
  4. SOUTH ABACO BLUE HOLES CONSERVATION AREA  A huge 34,000 acre (53 square miles) swathe of South Abaco to the west of the E D Highway, incorporating 4 inland blue holes and important cave systems, and 13 offshore blue holes. This is an area of mainly pine forest on land and low waters at sea, with an anticipated value for eco-tourism

Here are the BNT maps showing the extent of each area. Far more information will be found via the link to the report given above.

FLAMINGO TONGUE SNAILS: ALL YOU NEED TO KNOW


Cyphoma_gibbosum Clark Anderson - Aquaimages

FLAMINGO TONGUE SNAILS: ALL YOU NEED TO KNOW

I wrote about FLAMINGO TONGUE SNAILS Cyphoma gibbous more than two years ago. They have not changed noticeably since then but this site has – in scope, available material and audience. So I am revisiting these small marine gastropod molluscs, which are related to cowries. The live animal is brightly coloured and strikingly patterned, but that colour only exists in the ‘live’ parts – the ‘mantle’. The shell itself is usually pale and characterised by  a thick ridge round the middle. These snails live in the tropical waters of the Caribbean and the wider western Atlantic. Whether alive or dead, they are gratifyingly easy to identify.

FEEDING ON A CORAL STEM

This snail is snacking on a coral stem, leaving a feeding track behind it. The structural shell ridge is clearly visible beneath the distinctively marked live tissue of these creatures.

Flamingo Tongue LASZLO ILYES Cyphoma_gibbosum_(living)_2

The flamingo tongue feeds by browsing on soft corals. Adult females attach eggs to coral which they have recently fed upon. About 10 days later, the larvae hatch. They eventually settle onto other gorgonian corals such as Sea Fans. Juveniles tend to live on the underside of coral branches, while adults are far more visible and mobile. Where the snail leaves a feeding scar, the corals can regrow the polyps, and therefore the snail’s feeding preference is generally not harmful to the coral.

Flamingo_Tongue_Snail_on_Soft_Coral_LASZLO ILYES

The principal purpose of the mantle of  tissue over the shell is as the creature’s breathing apparatus.  The tissue absorbs oxygen and releases carbon dioxide. As I have seen it described (unkindly?) “it’s basically their lungs, stretched out over their rather boring-looking shell”. 

Flamingo Tongue, Abaco (Char Albury)

This snail species, once common, is becoming rarer. The natural predators include Hogfish, Pufferfish and Spiny Lobsters, though the spotted mantle provides some defence by being rather unpalatable. Gorgonian corals contain natural toxins and instead of secreting these, the snail stores them. This supplements the defence provided by its APOSEMATIC COLORATION, the vivid colour and /or pattern warning sign to predators found in many species.

It comes as little surprise to learn that man is now considered to be the greatest menace to these little  creatures, and the reason for their significant decline in numbers. The threat comes from snorkelers and divers who mistakenly / ignorantly think that the colour of the mantle is the shell of the animal, collect up a whole bunch from the reef, and in due course are left with… “boring-looking shells” (see photos below). Don’t be a collector; be a protector…

These photos are of flamingo tongue shells from the Delphi Club Collection. Until I read the ‘boring-looking shell’ comment, I believed everyone thought they were rather lovely… I did, anyway. You decide!

Finally, a couple of videos. The first is rather charmingly titled ‘FLAMINGO TONGUES DOING…. SOMETHING’. Any (printable but amusing) suggestions via the Comment box are welcome. The second punchily summarises this post in 30 seconds. Maybe that’s all that was needed!

Doh! Reading through this after posting I can’t remove from my mind the likeness of Homer Simpson on the snail in Melissa’s photo (2). I had to  check it out and… it’s uncanny!
