BANANAQUITS ON ABACO (GUEST PHOTOS)

This is the best job in the world (#it’snotajob #it’sapastime #duh!yougetpaidinajob). I get to choose what to write about and what photos to use. And it’s all enjoyable, interesting, and totally new (to me) within the last 10 years. Bananaquits are another favourite small bird of mine. Charmaine Albury takes great Abaco wildlife photos – birds, butterflies, insects, shells and more – on Man-o-War Cay and beyond. It’s time to showcase some of her bananaquit photos. Let’s go!

Juvenile bananaquits have their own totally adorbz qualities, as I have observed BEFORE.

Bananaquits are readily attracted to gardens. They can used their sharp curved beaks to drink from hummingbird feeders. Or why not try Charmaine’s idea for a free-to-make bananaquit bar – look how successful it is!

CUBAN PEWEES AT THE NEEM FARM, ABACO

CUBAN PEWEES AT THE NEEM FARM, ABACO

The Abaco Neem Farm just off the highway about 20 minutes south of The (one and only) Roundabout is about much more than the neem plants and the resultant products sold at the well-known shop in Marsh Harbour. The many varieties of fruit tree, the grasses and the wild flowers, the coppice, the pine forest, the open land and the pond that make up the extensive property provide a wonderful haven for birds, butterflies, moths and bees (there are hives too). It’s a great place for birding, and the owner Nick is rightly proud of the peaceful ambience of the farm. On a bright day, the place is alive with birdsong.

Among my favourite small birds found there are two species that are so tame and inquisitive that it is often possible to move slowly right up to them. The blue-gray gnatcatcher is one. The cuban pewee is another. This pewee was flitting about the edge of the coppice, hawking for insects and quite unconcerned by our presence. Sadly I only had ‘hated camera’ with me, having thrown ‘beloved camera’ into the sea a couple of days before, photographing shorebirds (and thence into the trash bin). So I’m not wholly pleased with the results, either for clarity or for colour. Needless to say, hated camera always has the last laugh…

Identification of the various flycatcher species e.g. CUBAN PEWEE, LA SAGRA’S FLYCATCHER, LOGGERHEAD KINGBIRD and GRAY KINGBIRD can be tricky. The simplest way to distinguish the cuban pewee is to remember that it is a small bird (so, not a kingbird); and that its informal name is ‘crescent-eyed pewee’ due to the very noticeable white crescent behind the eye. And as Liann Key Kaighin reminds me in a comment, these little birds also answer to the name Tom Fool…

PS I don’t go in much for beauty products (far far too late), but the Neem Salve is fantastic for minor injuries: cuts, grazes, bruises, small burns and so on. Well, it works for me.

DOVE LOVE: APPRECIATING PIGEONS ON ABACO

DOVE LOVE: APPRECIATING PIGEONS ON ABACO

Monday was International Pigeon Appreciation Day 2016, apparently. I’m not a huge fan of limitless species being accorded their own special day each year: “Celebrate International Plankton Day – Be Kind to your Favourite Protozoa!” or “Global Millipede Day: Take an Arthropod for a Walk!”.

I’m not sure where pigeons come in all this. In many cities feral pigeons are considered vermin – yet people love to feed them, even the ones with rotted feet and one eye. Especially those ones. Pigeons may be pests in crop fields, yet HEROES in wartime. They may be decorative, yet are, regrettably, good sport and delicious.

I’ve decided to take a broad view with pigeons and doves (there’s no significant difference), and not to be sniffy about Columba and their special day. They are pretty birds and they deserve it. So I’m featuring some Abaco pigeons and doves to enjoy, representing every species found on Abaco – and a bonus dove from New Providence at the end.

The birds shown above represent the 8 species found on Abaco. However, not far away in New Providence, there is a beautiful pigeon that has not yet made its way over to Abaco and has yet to be introduced there. I am ambivalent about the deliberate introduction of alien species, because of the frequently very real risks to native species in terms of territory, habitat, food sources and so forth. But where there is no detectable threat to the local species, perhaps there is no great harm. I’d certainly like to see these lovely birds flying around – if possible, as a protected species…

WHALE-WATCHING: THE APPLIANCE OF SCIENCE

WHALE-WATCHING: THE APPLIANCE OF SCIENCE

The Bahamas Marine Mammal Research Organisation has just celebrated its 25th year of existence. It was formed in 1991. The omnivorous leviathan Amazonus giganticus emerged in 1994 and the invasive species Megacorpus googleii not until 1998. A full 10 years later the first garbled recordings of Sarahpalinus illogicus were made. And all the while, a watchful eye was being kept on the cetaceans of the Bahamas – researching, counting, measuring, identifying, recording, poop-scooping, analysing samples, tagging, comparing, protecting and conserving.

As the years passed, so the science and technology evolved and became more sophisticated. Researching became at the same time easier, yet more complex as the organisation’s remit expanded to accommodate the vast increase in data collection now made possible by refined techniques. Here are two very recent examples – 25th anniversary projects, in fact – with thanks to Charlotte, Diane, their team and their colleagues in linked organisations.

TAGGING BLAINVILLE’S BEAKED WHALES

Last month, a tagging project started, involving suction cups being attached to the backs of BLAINVILLE’S BEAKED WHALES. The purpose of the research is to compare the foraging efficiency of the whales in Abaco waters with those of Andros, the second part of the project. I imagine this will provide valuable insights into the whale movements and behaviours in each location as well as such issues as the comparative availability of the food supply, and other factors that may affect expected foraging patterns.

The tag is tracked for 18 hours, after which it is retrieved and the recordings can then be analysed back at BMMRO HQ in Sandy Point. So far, an adult male, a young male and two adult females have been tagged. Each female had a calf, but these were not tagged.

AERIAL PHOTOGRAMMETRY USING A HEXACOPTER

Drone technology is rapidly expanding as new uses for them are devised. BMMRO in conjunction with NOAA have used a sophisticated HEXACOPTER to take the first  PHOTOGRAMMETRY images of Blainville’s beaked whales. These aerial photographs were taken from approximately 100ft altitude. But note: not just anyone with a $50 drone can do this: the project required flight clearance from the Bahamas Department of Civil Aviation and a permit for research on marine mammals granted by the Bahamas Department of Marine Resources.

Photogrammetry: the science of making measurements from photographs. Applications include satellite tracking of the relative positioning and alterations in all Earth environments (e.g. tectonic motions etc), research on the swimming of fish, of bird or insect flight, and other relative motion processes. The results are used to guide and match the results of computational models of the natural systems. They help to invalidate or confirm new theories, to design novel vehicles or new methods for predicting or/and controlling the consequences of earthquakes, tsunamis etc, or to understand the flow of fluids next to solid structures, and many other processes.

MAKE FRIENDS WITH ANEMONE (2):  SPECTACULAR REEF PLANTS

Going snorkelling? Planning a scuba day on the reef? You’ll see wonderful fish and amazing coral for sure. But sometimes the beauty of the plant-life on the reef can be overlooked. Check out the anemone in the header image, with the camouflaged cleaner shrimps playing around it. You wouldn’t want to miss a sight like that. The many and varied forms and colours of anemone on the reefs of the Bahamas make up a vital component of a spectacular underwater world.

A FROG CALLED TOAD: NEW AMPHIBIAN SPECIES FOR ABACO

A FROG CALLED TOAD: NEW AMPHIBIAN SPECIES FOR ABACO

Welcome to the wonderful world of the tiny Eastern narrow-mouthed toad. This non-native species has just been discovered on Abaco and formally identified. It looks like a toad. It’s called a toad. It’s actually a frog. There’s a song from the ’60s (dread decade) called ‘Walkin’ my cat named dog…’. But no one has come up with ‘Check out my frog named toad’. Yet.

Eastern narrow-mouthed toad (Sean Giery ABSCI)

THE FIRST EVIDENCE ON ABACO

A year ago, Sean Giery reported on the excellent ABACO SCIENTIST website that he had heard the unmistakeable (to him) mating call of Eastern narrow-mouthed toads Gastrophryne carolinensis in the Marsh Harbour area, Abaco. Denizens of south-eastern US, the species had previously only been recorded in the Bahamas on Grand Bahama and New Providence.

Sean estimated that he heard several dozen of these tiny 2.5cm frogs, suggesting a well-established population. A veritable Frog Chorus.** However, he wasn’t able to obtain a specimen, so his identification was by sound alone – vividly described as “like a bleating lamb with a stuffy nose”. You can read the full article from last May HERE.

THE FIRST SPECIMEN IS FOUND 

In a further article one year later HERE, Sean relates how he was called to the home of alert student Donte Richard, who had remembered the original post. This was in a different area of MH, suggesting a spread of population. Others had reported the distinctive bleating calls as well. Identification of the specimen frog was made by researchers at the Frank Kenyon Centre, Friends of the Environment, and confirms a new addition to Abaco’s vertebrate fauna.

WHERE WERE THEY FOUND?

MIGHT THEY BE HARMFUL? 

Sean writes: “With Abaco added to the list of islands we see a distribution pattern that echoes another recent invader (the corn snake). Perhaps they share a similar route of entry? Whether or not the narrow-mouthed toad poses any real threat to Abaco’s native flora and fauna is unknown. However, given their diet of small invertebrates (ants, mites, termites), it seems unlikely that they could pose any substantial risk. That said, who knows?”

WHAT DO THEY LOOK LIKE WITH NO CLOTHES ON?

CAN I BUY ONE AS A PET?

Yes, by all means you can. But they are remarkably expensive for a 2.5cm creature. ‘Urban Jungle Reptile’ sells them for $80 each. You might need a pair. But you’d be better off hanging round Marsh Harbour in May with a small bucket and spade. And they are useless for taking on walks. You’d be far better off with the cat named dog…

MUSCOVY DUCKS: THE MATING GAME…


Muscovy Duck, Abaco, Bahama (Gerlinde Taurer)

MUSCOVY DUCKS: THE MATING GAME…

This is going to be a bit awkward for me. And for you. We are all going to have to be very adult about this. If you are sensitive about discussing… intimacies, then look away now. Because we are going to have to confront the facts with courage and fortitude. Ducks have sex. Oh, you didn’t quite catch that? They have Sex. SEX. SEX. Let’s call it something less.. well, I think mating is the correct word, although given the fact that the female suffers total submersion during the proceedings, ‘ducking’ would not be wholly out of place…

On Abaco, there are a number of muscovy ducks, all tame ones such as Perry Maillis’s at Gilpin Point shown in the Header image. They are not strictly an ‘official’ bird species of Abaco, but instead come into the classification “exotics”, in other words avian ‘also-rans’. This category also includes mallards, macaws and (for now) PEAFOWL – though I would fight to near-death to have these ranked as an established breeding introduced species (cf bobwhites), i.e. ‘proper’ Abaco birds. Many-time descendants of a few original tame birds, the population now is entirely feral and self-sustaining. 

Cairina_moschata_reproduction (Ianare Sevi wiki)

Muscovy ducks Cairina moschata turn out to be very interesting in the area of ‘Spring relationships’ (mallards and other ducks too, for that matter). A quick piece of research about them unearthed one unbeatable nugget of anatidaean anatomy: male muscovy ducks have spiralled penises which can become erect to 20 cm in one third of a second… Females have vaginas that spiral in the opposite direction to try to limit forced copulation by males, with ‘blind pouches’ if the female is unreceptive to advances…

So there you have it. Impressively rapid reactions from the male. And an equally clever response from the female. Something like this:

Male & Female Duck Corkscrewsimgres

NERVOUS DISPOSITION? STOP READING RIGHT NOW!

I once photographed the muscovy duck mating sequence (not on Abaco). Here are some images from the procedure. Until I looked at the images on my computer, I didn’t realise I had ‘caught’ (photo #2) the pink corkscrew in the process of inflation. So to speak. And with apologies for indelicacy.

SPRINGTIME. I THINK IT’S TIME TO FIND MYSELF… A LADY FRIEND

OH MY GOODNESS. THAT “1/3 OF A SECOND THING” IS STARTING TO HAPPEN…

QUICK! AHA! SHE LOOKS NICE. LET’S SEE HOW THINGS DEVELOP.

THAT SINKING FEELING…

THAT SUNKEN FEELING…

HEY! WHERE ON EARTH HAS SHE GOT TO?

OH! HELLO, DEAREST…

HOLD ON  AGAIN…. JUST A…. MOMENT…

YAY! I ENJOYED THAT

BLEURGHHHHHHH… ME TOO… I THINK?      

AH YES, ALL OK NOW. PLEASURE TO MEET YOU
