SPACE DEBRIS ON ABACO: YES, IT IS ROCKET SCIENCE

December has seen two remarkable events on Abaco. First, a huge dead sperm whale (estimated 50′ long) washed up at Bahama Palm Shores. Sharks had already had a go at it, and it was beginning to putrefy. An autopsy was unable to determine the cause of death (ship-strike is presumably a contender). It continued to decompose on the shoreline, becoming extremely… well, best kept at a distance. And upwind of it. I’ll post about the sad end of this magnificent creature – the largest marine mammal in the Bahamas – in a couple of weeks, after the festivities at Rolling Harbour Towers have calmed down.

———————————

STOP PRESS 🚀 you haven’t even reached the rocket part of this yet, but just to say that a few hours after posting this article, other reports of bits of Mr Musk’s rocket debris washed up on beaches are coming in  – Tahiti Beach EC, and just now from BMMRO at Sandy Point. I’ll update tomorrow. 🚀

The second big news event for South Abaco was the discovery of a massive piece of (formerly) airborne debris drifting onto the BPS beach. Everyone was hoping the item wasn’t part of a plane fuselage, as it initially appeared to be. From the initial photos it looked to me like something from a rocket launch, maybe part of a booster rocket. It reminded me of the 12 foot part of a booster rocket fairing from the Atlas 5 rocket which launched Curiosity on its Mars mission, that washed up on the Delphi beach in early 2012. The men in black eventually came to reclaim it… More on that HERE

THIS REALLY IS ROCKET SCIENCE THEN?

Quite soon the mystery of the object’s purpose and origin began to get clearer. Luc Lavallee was quick to recognise the red external markings as matching Elon Musk’s logo, as used by his SpaceX venture. Events moved quickly. Contact with Musk’s operation confirmed that this was indeed “one of theirs”, a part from the latest launch a few days before.

SO WHAT ON EARTH* WAS THIS CHUNK OF SPACE DEBRIS?

In the end the item was identified as part of the shroud from a Falcon 9 rocket. There was plenty of opportunity to take a good look at some of the workings. There’s potential here for some quality beach-combing (who would not want an ‘Actuator Latch Right’ rod in their living room?). There are interesting legal considerations in this type of situation… [Worried reader: please, no, I beg you]. Moving on, here’s a selection of rocket bits for contemplation.

More info was gathered, including the discovery of an astounding video from a camera fastened to a Falcon 9 rocket’s payload fairing, showing the nose cone spinning through space after its separation on a satellite launch earlier this year.

WHAT DOES A ROCKET SHROUD DO?

The nose shroud shields satellites during final preflight preparations and the early stages of launch. Once the rocket reaches space — an altitude above 100 kms / 62 miles — it jettisons the payload fairing to fall back into the ocean. The Falcon 9’s fairing is released in two halves, like a clamshell.

* This is the sort of occasion when people write ‘no pun intended’, though in fact they generally intend one, just rather a feeble one. Like mine, in fact.

PAINTED BUNTINGPainted Bunting, Abaco (Erik Gauger)

One of the Winterval traditions at Rolling Harbour HQ – that haven of unreliable natural science powered by lazy insouciance and characterised by a regrettably unserious approach – is to break the rule that (mostly) forbids reposting old material without good reason (which there occasionally is). This means marking the imminence of Christmas with bunting. And indeed buntings, those lovely birds beautifully painted by nature. Nothing says ‘Happy Christmas’ better than a flock of PABU!

Painted Bunting, Abaco (Tara Lavallee)

It’s hard to imagine a more Christmassy little bird than the Painted Bunting. Bright blue, red, green primary colours straight from a child’s paintbox make for a spectacular bird to grace the festive season. These are migratory winter residents, and the first reports of the bright and beautiful males on Abaco started to appear in late October. Some will stay around until March.

This is my opportunity to wish a very Happy Christmas or [insert preferred seasonal appellation] to everyone who visits Rolling Harbour and especially those who, having done so, return for more! There could of course be anything from 600,000+ individuals who called in once, were put-off and never came back… to one sadly crazed person who has been pressing the ‘read’ button 600,000+ times over the last few years. If the former, thanks for trying, sorry to disappoint. If the latter, keep up the good work, buddy.

SANDHILL CRANE: ANOTHER NEW BIRD FOR ABACO, BAHAMAS


Sandhill Crane, Abaco Bahamas - a first-ever sighting (Elwood Bracey)

SANDHILL CRANE: ANOTHER NEW BIRD FOR ABACO, BAHAMAS

Still they keep arriving, the new birds that have never before graced the shores of Abaco Recently it was a Canada warbler, at the lower end of the size scale. The elegant sandhill crane (Antigone canadensis) is the 10th new species for Abaco since the publication of The Birds of Abaco in March 2014. If you are wondering why the bird is not called Grus canadensis any longer, it’s because the genus of the bird was reclassified by the ABA in 2016. Out with dreary old Grus and in with exciting Oedipus’s daughter (or was she his half-sister? They… erm… had the same mother… Discuss, using both sides of the exam paper) in Greek mythology…

As the crane’s canadensis suggests and as range map shows, these are birds of North America, breeding mainly in Canada. In winter they head south to the warmth, reaching Florida as winter migrants. As you can see, the northern part of Florida and also Cuba have small year-round breeding populations. Zero zilch zip nada in the Bahamas.

THE ABACO SIGHTINGS, DECEMBER 2018

Sandhill Crane, Abaco Bahamas - a first-ever sighting (Kaderin Mills)

At 9.00 am on December 13, the bird above was photographed by Kaderin Mills (of the Bahamas National Trust) on Little Abaco, at the Fox Town Primary School, Crown Haven. The day before, the 12th, the school Principal Mrs Curry had seen the bird in the school grounds feeding on the grass. A couple of phone ‘sighting shots’ were taken before it flew off. Next day it returned, word spread and Kadie Mills recorded the bird officially and put it on eBird to give the newcomer some due publicity. By the early afternoon, Woody Bracey had been told about the bird, and went to take photos. He saw it in the same place the next day too.

Sandhill Crane, Abaco Bahamas - a first-ever sighting (Elwood Bracey)

OK, FIRST FOR ABACO – AND THE BAHAMAS TOO?

The strict answer is, no. Many years ago, there was a single report of a Sandhill Crane on Andros. It’s not known if the sighting was officially confirmed, but according to expert Bruce Hallett there was a photograph, and the late Tony White, then ‘recorder’ for the Bahamas, saw it. There are no available records, but Tony’s authority on issues around Bahamas birds was (and remains) absolute.

12 CAREFULLY SELECTED SANDHILL CRANE FACTS

  • These cranes are social birds, usually living in pairs or in family groups 
  • Their calls are loud and far-reaching, like a huge crows with a sore throat (below) 
  • Mated pairs engage in ‘unison calling’, standing close and duetting amorously
  • Hatchlings are fully-formed and can leave the nest within a day.
  • Juveniles are known as colts (whichever their gender, it seems)
  • They have an impressive wingspan as adults, from about 5′ to 7′ 6″
  • They are able to soar in flight, using thermals to obtain lift and stay aloft for hours
  • Flocks of cranes may be huge – sometimes estimated at over 10,000 individuals
  • Their ancestors are among the oldest fossils of any bird species, at around 2.5 M  years
  • Vagrants have been found as far off piste as Britain (1981, 1991 only), China and Japan
  • Many predators call them dinner; but they can kick and stab with their bills in defence
  • The sandhills of Cuba form the smallest breeding population, around 300

STAR ANIS ON ABACO


Smooth-billed Anis, Bahamas (Paul Harding)

STAR ANIS ON ABACO

The Smooth-billed Ani (Crotophaga ani) – aka Cemetery Bird – is the third member of the cuckoo family found on Abaco, the others being the MANGROVE CUCKOO and the YELLOW-BILLED CUCKOO. You can (it’s voluntary) find out more about them in an earlier article HERE. 

I have returned to these engagingly gregarious birds and their raucous ways because Paul Harding has recently captured a sequence of  a small group of anis behaving so endearingly that they are irresistible. Not for them the oddly incompetent fluttering flight, nor the disorganised, unbalanced landing technique. It’s simply a matter of getting settled on a branch, and then making room for one more in the middle (or perhaps resisting it…).

KIRTLAND’S WARBLERS ON ABACO: A FIRST FOR THE CAYS


Kirtland's Warble, Green Turtle Cay, Abaco Bahamas (Sally Chisholm)

KIRTLAND’S WARBLERS ON ABACO: A FIRST FOR THE CAYS

I last wrote in April about the rare Kirtland’s warbler Setophaga kirtlandii that, in very small isolated numbers, overwinters on Abaco. You can get to the article HERE. You’ll find plenty of information, a range map, notes about the eponymous Mr Kirtland, and lots of good photos (none mine except the joke one – I messed up my one chance out of 4 birds encountered in the National Park). So I won’t go over the ground again…

I’m returning to this near-threatened species now because there has been a very exciting development for Abaco for the KIWA. Towards the end of last month, 2 birds were found over a couple of days at a location on Green Turtle Cay. Having now checked all reported sightings for Abaco since time immemorial (or at least from when eBird began), I believe that this may be the first time a Kirtland’s warbler has been reported on any of the cays. Certainly when we were researching The Birds of Abaco, we found no evidence of KIWA reports from the cays. Sightings are anyway few and far between (not even annual), and mostly on a ‘right place right time a hunch and a large slice of luck’ basis.

Kirtland's Warble, Green Turtle Cay, Abaco Bahamas (Sally Chisholm)

The first sighting of the season, on Ocotober 27,  was (surprisingly) at Sandy Point, when Woody Bracey took a party of 3 birding for the day. Most KIWA sightings are in south Abaco, with selected areas of the huge National Forest being much the most likely places. There were in fact 2 birds seen – here’s a photograph of one of them. Sandy Point was an unexpected location, but they were on the mainland and in the south – a great ‘get’ by any standards, but not unique for the area.

AN EXCITING SIGHTING

On November 22 at 08.30, Sally Chisholm was birdwatching on GTC when she suddenly came across an unmistakeable KIWA, seeing it closely and clearly: “gray back with dark striping, gray head with white broken eye ring, pale yellow breast with small dark spots”. It was pumping its tail (‘tail-wagging’ J. Bond) characteristically, and eating the berries from a palm tree (see header image). Sally heard its repeated “chip” call, typical of the KIWA. Furthermore, a second bird was returning the call, though she could not see it.

KIWA CHIP CALL Paul Driver / Xeno Canto

Kirtland's Warble, Green Turtle Cay, Abaco Bahamas (Sally Chisholm)

Two days later, in the early morning on November 24, Sally returned to the same location and saw a single bird, clearly one (or perhaps the other) of the two birds already seen / heard. She got a fine clear shot this time, too. 

Kirtland's Warble, Green Turtle Cay, Abaco Bahamas (Sally Chisholm)

I’m not by any stretch of the imagination a Kirtland’s expert (not even a bird expert, if I’m honest). The photos seem to me to show a young bird (compared with ones I have seen) and I wonder if they are juvenile adults (as it were) on their first migration from the jack pines of Michigan. Comments on this remark invited and welcomed… No matter: the great thing is that, whatever the age of the bird, photo #1 is, as far as I can tell, the first visual confirmation of a KIWA sighting on an Abaco cay. It’s a privilege to be able to give it a wider audience.

WHAT ARE THE MAIN THREATS TO THE SPECIES?

  • Mankind is the primary threat. The breeding areas are particularly vulnerable from deforestation and clearance of the jack pines that are essential for successful nesting and breeding – and therefore the survival of the species
  • Encroachment of development is another threat, as with so many species
  • There is a further threat of nest parasitism by brown-headed cowbirds, to which KIWAs are especially vulnerable
  • In the winter grounds where the habitat is mostly remote or in protected areas, there is rather less of a problem from these factors – for now at least
  • Overall, habitat degradation at one end of the migration – in particular the breeding grounds – poses a serious risk; at both ends, extinction could loom again. Check out the very limited range of the KIWA and you’ll see the point at once

BAHAMAS REEF FISH (50): TOBACCO BASSLET


Tobacco Basslet (Serranus tabacarius) Bahamas (Melinda Riger / GB Scuba)

BAHAMAS REEF FISH (50): TOBACCO BASSLET

Welcome to #50 in the Bahamas Reef Fish series. I chose this fish to honour the landmark before thinking about its features. Grumpy. Also, associated with a narcotic and dangerous drug. And a fish one probably wouldn’t bother to smoke (even if one could get it to light underwater). In the Bahamas you’ll find these little fish around the coral reefs where they play their part as reef denizens, which includes being prey to larger species. If one looks them up online, however, the overwhelming impression from the websites and images available is that they exist largely for the benefit of the aquarium industry.

Tobacco Basslet (Serranus tabacarius) Bahamas (Melinda Riger / GB Scuba)

Tobacco basslets (Serranus tabacarius) – more commonly just called tobacco fish or tobaccofish – are related to the HARLEQUIN BASS(LET), a species that was most unfairly included as #9 in my parallel WTF? series among all the seriously weird sea creatures that feature in that category. A wrong I must right one day.

Tobacco Basslet (Serranus tabacarius) Bahamas (Melinda Riger / GB Scuba)

Tobacco fish are considered to be hardy, unaggressive (except towards the tiny fishes and crustaceans they feed on) but apparently they need quite a large tank to hold them. The ocean might be suitably large for the purpose. Especially as it seems that in an aquarium there needs to be a cover on top: “these fish are expert jumpers…“, as one source puts it…

BESIDES THE BAHAMAS & AQUARIUMS WHERE ELSE DO THEY LIVE?

TOBACCO BASSLET RANGE MAP

APART FROM THE HIGH JUMP THING, ANY OTHER TRICKS?

Yes indeed. The Tobacco Basslet is hermaphroditic, like all other members of its genus.

DON’T LEAVE IT AT THAT… HOW DO THEY, YOU KNOW?

I didn’t want you to ask. All their FB pages say “It’s complicated“, but here’s a rough idea…

  • All individuals start life as simultaneous hermaphrodites (with sex organs of both sexes)
  • The largest fish lose their female functions and become active sperm-producing males
  • Each male leads a group of hermaphrodites and protects them from other males 
  • This gives them exclusive rights to the female parts of members of their ‘harem’
  • Sometimes hermies may use their male bits to join in & release sperm – ‘streaking’
  • There are rarer mating strategies… Oh heck, please look at the abstract of a scientific paper for details. I had to! And all because you, gentle reader, asked that question.

With some relief, here is very short video. It probably doesn’t accurately show how Tobacco fish might behave on a Bahamian reef. In captivity, from the look of it, they get pushed around by bigger fish. But maybe, if their co-residents are carefully selected, the bonus is that they don’t risk getting eaten.

OPTIONAL MUSICAL INTERLUDE

There are no songs ever that mention tobacco fish or tobacco basslets (though lots involve bass). And more oddly, apart from a couple of old blues songs the only truly mainstream song about tobacco by name (as opposed to content) is Tobacco Road, a song as frequently and thoroughly covered as an aquarium tank containing jumpy tobacco fish.

BAHAMAS BIRDS FOR A NEW GENERATION


Red-tailed Hawk, Bahamas (Chris Johnson)

BAHAMAS BIRDS FOR A NEW GENERATION

It is axiomatic that people tend towards birding – if at all – in later life. Not the scientists, of course: they must commit themselves to the study of natural history at an early age, collecting qualifications by degrees (as it were), through Masters, Field Work, their first posts, PhDs and beyond.

American Redstart (m), Bahamas (Chris Johnson)

American Redstart (m)

I didn’t take a very active interest in birds until the first time I investigated Central Park NYC and saw a blue jay. Followed by a cardinal… a red-tailed hawk… chickadees… American robins (or ‘Mercan rubbins‘, as I was informed). These were alien species for a European, and they awoke my interest.

Brown Pelican, Bahamas (Chris Johnson)

On later trips to NYC I have always spent a day in CP, wandering from end to end, spending time in the hotspots like The Ramble, the JO Reservoir, and the pretty Loch trail to the north, and wondering at the huge and expensive birding hardware toted by those around me (while knowing I didn’t want it). And then a visit to Prospect Park Brooklyn too, if I have the time. More recently came Abaco, and a whole new world of wildlife that has captivated me…

Hermit Thrush, Bahamas (Chris Johnson)

This reminiscence by an oldster brings me to Chris Johnson, a young Bahamian man who will be familiar to many readers of this blog. I first encountered him when I was researching the Bahama Oriole and discovered that he, in his early teens, had found one on a trip to Andros and photographed it. It was a pleasure to be able to include the image in my article. 

Hooded Warbler, Bahamas (Chris Johnson)

Since then, Chris’s birding and photographic skills have rapidly developed and his reputation is growing too. This summer he was one of 12 students chosen to attend Cornell University Lab of Ornithology for their Young Birder’s Event in Ithaca NY, a great tribute to his accomplishments and a wonderful opportunity too. It is worth noting that Chris is the first Bahamian to be invited to attend this event.

Loggerhead Kingbird, Bahamas (Chris Johnson)

Chris is also beginning to make his own presentations, as he did recently to the Bird Club of New Providence. It won’t be long before he is leading bird groups – in fact, he is probably doing this already.

Another impressive feature of Chris’s birding is his photography. I have watched the progression online with interest. The crispness of his images, the composition and the right ‘take’ to make the best of each bird is wonderful, and he has a great eye for a neat shot – for example in the header image I have chosen, with its awareness of the effective use of dark and light.

Black-and-white Warbler, Bahamas (Chris Johnson)

Black-and-white Warbler

I should say that I have never met Chris, although we have occasionally been in touch. I am featuring him because I believe he and other young people of his age – Chris is 17 – are the future for birding, for wildlife, for species protection and for habitat conservation. The older generation will move on and the ‘middles’ may begin to take an interest in the birds around them. But Chris’s generation are the ones who can make a difference in the future. As things stand right now, they may have to. It’s a huge responsibility for them, but it’s one our generation is in the process of transferring to them.

I hope you have enjoyed the small gallery of Chris’s photographs displayed here. If you are interested in the birds of the Bahamas, keep an eye on him and others like him. They need all the encouragement we can give them.
