SHARING SHEARWATER SEASHORE SHOCK ON ABACO…


Great_Shearwater_RWDz9 Dick DanielsSHARING SHEARWATER SEASHORE SHOCK ON ABACO…

I return reluctantly to the “Great Shearwater” phenomenon to give, I hope, closure to the topic for this season and with luck for several years to come. A great many people have engaged with the debate about the large number unfortunate birds found either dead or dying in the water or (especially) on the beaches of Abaco and beyond. You can see the original post, a tabulation and map based on the reports I received or came across, and the views of the experts HERE

This occurrence appears to have declined considerably from its peak last week, presumably because the migration has moved rapidly northwards. Already, reports from the eastern US Atlantic coast (e.g. Cape May) of a great shearwater influx are coming in, so we must hope that the attrition rate in the Northern Bahamas has stopped, or will stop within the next few days. This is evidenced by this FB clip from Tom Reed, a photographic contributor to THE BIRDS OF ABACO

The ABA (American Birding Association) has taken an interest in the problem on Abaco, and reported the incidence of shearwater die-off HERE. For the sake of completeness, I have updated reports I have received or found over the last few days below, together with an updated distribution map. More sad images are included because, pitiful though they are, photographs are of real assistance in the study of migratory die-off. For example, it is likely that juvenile birds are more likely to be affected by exhaustion in the course of their 10,000 mile journey than adults. Photos enable an assessment of the age of the birds to be made.

Exhausted shearwater, Delphi beach. Is this a juvenile, less able to make a huge journey than an adult?Great Shearwater, Delphi, Abaco (Sharon Elliott)The yellow tip to this bird’s beak shows that it is a different species of shearwater, the Cory’s.  Like the Greats, these birds are also rare transients on Abaco, and also make long-distance migrations. A Cory’s was photographed a couple of weeks ago swimming happily off the Delphi beach. This one has obviously run out of stamina. It has the chance to recover, but it is vulnerable in this state; and turkey vultures are quick to move in on fatalities…

 UPDATED REPORTS (SINCE JUNE 24) IN RED
  • Delphi Club Beach – 20 plus + 1
  • Schooner Bay – 5
  • Bahama Palm Shores – ‘many many’ dead birds washed up on the shore
  • Casuarina Beach – 1
  • Cherokee (Watching Bay) – 3 or 4
  • Cherokee (Winding Bay) – 4
  • Little Harbour – 3
  • Marsh Harbour area – about 5
  • Great Guana Cay, southern end   – 1 (possibly a gull)
  • Tilloo Cay – 13 at least on Junk Beach, more than ever seen (see photos below)
  • Elbow Cay – 2 + 1 Atlantic side beach near Abaco Inn
  • Elbow Cay – 2, North End
  • Green Turtle Cay beach – 2
  • Green Turtle Cay, offshore – “a lot in the water”
  • Man-o-War Cay – 1 by the roadside
  • Ocean 20m from HT Lighthouse – 2 in the sea

also Exuma Sound (5 birds), Shroud Cay Exuma (gull?”), Briland Beach,Harbour Island Eleuthera (“some” + 4) , and Church Bay, South Eleuthera – 10 + 2

Ellen Bentz, who reported the Church Bay birds, has frozen 3 of them for research purposes; it will be extremely interesting to see what results from their examination, from the ages of the birds to condition to likely cause of death. She also took photographs to aid species identification and diagnostic efforts.

WHERE DO THESE BIRDS COME FROM & WHERE DO THEY GO?
Sean Giery of the excellent ABACO SCIENTIST has also commented on the recent phenomenon, concluding “…if you haven’t looked up Gough Island, the probable origin of these Greater Shearwaters, do. Use Google Maps to get an impression of how far these amazing birds travel. It’s truly amazing.” By great good fortune, I’ve done the legwork for you… Let’s take a closer look.
Great shearwaters breed almost exclusively the small area of the globe that includes the Gough Islands, Tristan da Cunha and a few lesser-known islands in that area. There is also a small breeding population in the Falklands. Whichever, they are not so very far from Antarctica. Their range, however, is massive and involves long migrations over the Atlantic ocean to the far north – as far as the Arctic – and back each year.

 And, as the shearwater flies, this is the distance from the breeding grounds to Abaco; 2/3 of their total journey. Now, factor in a first-season juvenile shearwater facing the vagaries of food supply, weather conditions and stamina… The fact that some die-off occurs every few years at some stage of the migration becomes less surprising.

I’ll conclude with a photo of a great shearwater flying ‘at the shear’, which I am certain is how best we’d like to think of these wonderful seabirds…

SIGNS OF GOOD BREEDING: PIPING PLOVERS IN SUMMER

SIGNS OF GOOD BREEDING: PIPING PLOVERS IN SUMMER

No apologies for writing again about Piping Plovers. This rare bird – only 8000 left in the world – overwinters in Florida, on the Gulf Coast, and to a notable extent in the Bahamas, very possibly on a beach near you. The peacefulness and cleanliness of Abaco’s pristine beaches provide the ideal habitat for the little PIPL to live safe and healthy lives during the winter, in preparation for their return to their summer breeding grounds. And breeding is what they are doing right now, up north. There are breeding populations on the Atlantic Coast, the Great Plains, and the Great Lakes. So I thought I’d feature a few images of what appears to be a rather successful season so far…

One of the best bird blogs around, one that I have recommended before, is called READINGS FROM THE NORTHSIDE. It is written in an informative yet witty style illustrated with excellent photos, and chronicles the daily avian goings-on on Long Beach Island NJ, an important nesting area for piping plovers. There are links with Todd Pover and Stephanie Egger, two scientists from the Conserve Wildlife Foundation of NJ who will be familiar to many Abaconians for the winter work they do with the plovers on Abaco. The photos below have almost all been taken this month as the PIPL chicks hatch and begin to find their feet in a big world.

Most regrettably, you’ll never see a Piping Plover chick on Abaco. The adult birds have left the Bahamian beaches and flown north before their breeding season begins. These little creatures are both rare and special at both ends of their migration range, so I’ll end with a video from the most excellent CONCH SALAD TV that is dedicated to these tiny wave-chasers. Abaco is one of the main areas for winter research into the piping plover population. Scientists visit the island to find the birds, count them, collect reports of sightings, check and identify tagged birds to determine their origin, and ensure the continuing good health of their habitat, without which the PIPL will be lost. You can find out more about this vital work carried out out by the CONSERVE WILDLIFE FOUNDATION OF NEW JERSEY HERE.

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

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.
