GREAT EGRETS: NOBLE (YET MISNAMED) HERONS

GREAT EGRETS: NOBLE (YET MISNAMED) HERONS

The Great Egret is actually a heron rather than an egret. It’s a Great Heron. All egrets are members of the heron family Ardeidae, but the converse is not true. As long ago as 1758, Linnaeus awarded the bird the binomial name Ardea alba i.e. ‘Heron white‘. Why it should have been so hard to stick to that authoritative nomenclature, I can’t imagine. Perhaps in time all heron and egret species became so hopelessly confusing for people that it ceased to matter much what they were called.

Great Egret, Bahamas (Nina Henry)

Maybe it was that type of carelessness that led to people from the mid-c19 onwards eyeing up GREGs as a source of hat feathers and other decorative necessities. As with flamingos and many other beautiful avian species, mankind’s millinery and other fashion needs were satisfied at the expense of gorgeous plumage. Actually, at the cost of the birds’ lives: they were simply shot in huge numbers. 

Great Egret, Bahamas (Nina Henry)

Healthy populations were decimated; for some species they never recovered. For others, the great egret among them, the passage of time and the passing of fashions – backed in many cases with conservation programs – have successfully restored the populations. In 1953 the National Audubon Society, which was formed at least in part to discourage the killing of birds for their feathers, took a decisive step in the cause of the great egret by making the bird the emblem of the organisation.

‘STAR ANIS’ ON ABACO, BAHAMAS


Smooth-billed Ani, TCGC Hole 11 - Becky Marvil

‘PRESENTING… A LARGE BILL’

The Smooth-billed Ani (Crotophaga ani) is one of three members of the cuckoo family found on Abaco, the others being the MANGROVE CUCKOO and the YELLOW-BILLED CUCKOO. Anis range from Florida and the Bahamas in the north down through the Caribbean to South America, where they are widespread.

Smooth Billed Ani, Abaco - Nina Henry 2a

Unlike their shy and retiring cuckoo cousins, anis are extrovert shouty birds that like to hang out in noisy gangs and family groups. They can often be found in low scrub, bickering, squawking, and generally fluttering around in a disorderly way. You’ll probably hear them from some way off, sounding like this:

Anis have advanced social, parenting and chick-rearing skills. They build a communal nest for the group, and all share in egg incubation and chick-feeding duties They may raise up to three broods in a season, which keeps the numbers up. Rather touchingly, the young of earlier broods help to feed more recent chicks.

It follows from this that unlike many other cuckoo species, the ani is not a brood parasite. So the species does not lay its eggs in the nests of other, smaller birds which then unwittingly rear the interloper(s), who in turn push the legitimate hatchlings out of the nest and get all the food and attention.

Smooth-billed Anis Abaco - Gerlinde Taurer d

 
I have tried to discover why an ani’s beak is as it is, without much success. Very often beak shape relates directly to the feeding habits and preferences of a species, but it is hard to see how a diet consisting mainly of insects and small reptiles such as lizards would account for such a prominently protuberant proboscis. Here is a close-up of the item in question.
 

Smooth-billed Ani, Abaco_Roselyn Pierce
 
 
On Abaco (and indeed elsewhere) Anis are sometimes known as ‘Cemetery Birds’, no doubt because of their all-black appearance (though their raucous tendencies would be quite inappropriate for a graveyard). However although at a distance these birds may look completely black, catch one in the sun at the right angle, and you’ll find that the plumage is far more varied, and with some intricate patterning.

Look for Anis in low scrubland and coppice, cultivated areas, perched in unsteady noisy rows on utility lines, or foraging on the ground.

Smooth-billed Ani, Abaco. Gerlinde Taurer c

The appearance and flying abilities of Anis are wonders to behold. As I wrote in The Birds of Abaco, “Their curious heavy beaks, their clumsy flight and their untidy take-off and landing routines suggest a design fault”.

The Philatelic Bureau of the Bahamas Postal Service is commendably committed to featuring the natural history of the Bahamas. Although probably not in the top-ten of anyone’s bird list, the ani nevertheless got its own stamp in a 1991 bird issue.

As far as I know, there is not yet a collective noun for a group of anis. There should be. I put forward A Commotion of Anis”

BLUEHEAD WRASSE: PRIVATE LIFE LAID BARE


bluehead_wrasse_thallasoma_bifasciatum_oregonstate-edu-pinterest

BLUEHEAD WRASSE: PRIVATE LIFE LAID BARE

The bluehead wrasse (or blue-headed wrasse) Thalassoma bifasciatum is a denizen of the coral reefs in the tropical waters of the western Atlantic Ocean. This bright little 4-inch fish is… a wrasse with a blue head. No more and no less. Unless it’s a juvenile. Then it is mainly bright yellow. It’s similar to BLUE TANG (aka ‘the Disney Dory’), which starts life bright yellow and grows up to be blue.

blue-head-wrasse-melinda-riger-g-b-scuba-copy

The species may be found singly, in pairs or small groups, or in schools.  They have an important role to play in the life of the reef. They are CLEANER FISH, vital to the health and wellbeing of the larger species they attend to, and thus of the reef itself. This is ‘cleaning symbiosis’, a relationship of mutual benefit. The big fish get cleaned; the little fish have a useful function and – importantly for them – therefore don’t get eaten. 

thalassoma_bifasciatum_bluehead_wrasse_san_salvador_island_bahamas-james-st-john-wiki

Having said that, blueheads are of course fair game as a snack for species that aren’t in the market for their cleaning services. Rather unfairly, some species that are quite content to let cleaner gobies pick around their gills and mouths are not so considerate of the wrasse (some types of grouper and moray eel, for example).

bluehead_wrasse

TELL US EXACTLY SEVEN BLUEHEAD WRASSE FACTS

  • Juveniles can alter the intensity of their colour, stripes & bars
  • The bluehead wrasse is a ‘protogynous sequential hermaphrodite’
  • All are born female**. Some change sex to male during maturation (see below)
  • Food includes zooplankton, small molluscs and small crustaceans…
  • …and parasites / other juicy bits (fungal growths, anyone?) from bigger fish
  • Main threats to the species are coral reef degradation / destruction and pollution
  • The bright colours invite aquarium use, but the trade in this species is not critical.

** Some sources suggest some are born male and remain male.

THE REMARKABLE SEX LIFE OF THE BLUEHEAD WRASSE

This is an unavoidable topic, I’m afraid. The bluehead’s sex life is the most interesting thing about them, and this is no time to be prudish. It has been the subject of extensive scientific research. As with many human relationships, “it’s complicated” but in a conch shell it boils down to this:

  • To recap, BWs are born female and as they mature, some become male.
  • Males reach an ‘initial phase’ when they can breed in groups with females
  • Some males grow larger & reach full colouration. This is the ‘terminal phase’
  • These large males aggressively chase away smaller ones & seek females to pair with
  • Their state of readiness is signalled by colour changes BUT the females know…
  • …that the smaller males have a sperm count higher than dominant males. 

blue-headed_wrasse_det (wiki)

As the excellent organisation OCEANA puts it: Bluehead Wrasses may reproduce in four different ways throughout their lifetime:  1) as a female in a group spawning event; 2) as a female in a pair spawning event within the territory of a large male; 3) as a small male in a group spawning event; and 4) as a dominant, terminal male in a pair spawning event within its own territory.

A cropped still from a video I took at Fowl Cay marine reserve. I’ve looked at dozens of images online and not found one that was all blue with a yellow end to its tail fin. Perhaps it is just an all-blue alpha male.bluehead-wrasse-fowl-cay-mr-abaco

ABACO’S THREE CUCKOO SPECIES

ABACO’S THREE CUCKOO SPECIES

There are 3 cuckoo species recorded for Abaco, all permanent residents. Two are relatively scarce; the third is the much-loved gregarious and raucous Ani. Recently I was contacted about a cuckoo seen on Man-O-War Cay. The photo revealed more of a glimpse than a sighting… but it clearly was not an all-black Ani. So here are the 3 species to admire in all their glory – and in the case of the first 2, to highlight the differences between them.

CURLY-TAILED LIZARDS ON ABACO, BAHAMAS


Curly-tailed Lizard, Abaco Bahamas (Keith Salvesen)

CURLY-TAILED LIZARDS ON ABACO, BAHAMAS

The northern curly-tailed lizard Leiocephalus carinatus, to give it its full name, resembles a tiny dragon with a twist in the tail. These little critters bask in the sun, or scuttle away into holes and crevices as you approach them. I suspect that even a confirmed herpophobic would find some charm in them. They are, of course, completely harmless to humans. 

Curly-tailed Lizard, Abaco Bahamas (Charles Skinner)

Surprisingly, the Bahamas is home not just to one but five different curly-tail species, and nine sub-species. Broadly-speaking, the variants are found on different and specific islands and have discrete local markings. Mostly they are brownish, but they may also be grey or with a greenish tinge like this one I recently photographed.

Curly-tailed Lizard, Abaco Bahamas (Keith Salvesen) Curly-tailed Lizard, Abaco Bahamas (Keith Salvesen)

Curly-tail males, being territorial, turn somewhat aggressive around breeding time, which is basically most the the year, from February to October. Behaviours indicative of their territorial claims include tail curling / uncurling (of course), head-bobbing, strutting about in an agitated way and inflating the sides of their necks in a threatening kind of way. The tiny-tails, 2″ long when born, are known as ‘hatchlings’.

An impressive poolside ‘double curly’Curly-tailed Lizard, Abaco Bahamas (Keith Salvesen)

THREATS TO CURLY TAILS

According to the Bahamas National Trust BNT, the main dangers to the curly-tails of the Bahamas are:

  • Dogs, cats, rats and introduced predators such as raccoons
  • Collection for the pet trade – curly tails are unprotected by CITES listing (also cute)
  • Collection of the rarer endemics by reptile enthusiasts seeking ‘exotics’
  • Development and habitat destruction (though it is noted that curly tails seem to adjust quite well in developed areas)

A curly tails sloughs its skin as it grows, as with snakes and other reptilesCurly-tailed Lizard, Abaco Bahamas (Charles Skinner)

WHY THE CURLY TAIL?

  • As mentioned above, for use in territorial posturing
  • In courtship displays by males to attract females (luckily a method not available to humans)
  • As a response to predators, confusing an attacker with movement at both ends
  • As a last resort, to detach to aid escape (the tail re-grows)
  • For fun and just because they can grow one and you cannot

BLACK WITCH MOTHS: HARBINGERS OF DEATH OR LOTTERY BANKERS?


Black Witch moths Ascalapha odorata (Charles J Sharp)

BLACK WITCH MOTHS: HARBINGERS OF DEATH OR LOTTERY BANKERS?

Black Witch moths Ascalapha odorata are seriously bad news. Or wonderfully good news, depending where you are and who you talk to. First, let’s look at some of the local names for the creature, from which you will get a pretty clear idea of its somewhat negative folklore status, as well as its area of distribution. I do this not to demonstrate how effortlessly I can ‘borrow’ from Wiki, but rather to show how a simple moth can give rise to widespread superstition and even fear. 

12 SCARY NAMES FOR ONE MOTH

  • Mariposa de la muerte (butterfly of death) – Mexico / Costa Rica
  • Pirpinto de la Yeta (something like ‘jinxing butterfly’) – Argentina
  • Tara Bruja (witch moth) – Venezuela)
  • Miquipapalotl (black death moth) – Mexico
  • Taparaco (something like ‘messenger in black’) – Peru
  • X-mahan-nah (‘invades your house’) – Mayan
  • Duppy Bat (lost soul / ghost /malevolent spirit) – Jamaica, Caribbean
  • Money Moth, Money Bat – Jamaica, Caribbean (including Bahamas)
  • Other names include Papillion-devil, La Sorcière Noire, Mourning moth, Sorrow moth.

WHICH MOTH? 

These very large moths (wingspan up to 7″)  are nocturnal, with females larger than the males. The diagnostic markings are a spot on each forewing shaped like a number nine or a comma. This spot is often green with orange highlights (seen in the header image). The hind wings are decorated with distinctive ‘eyes’. The overall effect is an example of aposematism – coloration or markings that act as signals to warn or repel predators. The link above will take you to an excellent Wiki article on the topic, including the debate on the topic between Alfred Russel Wallace and  Charles Darwin 

The stripy larval caterpillar can grow up to 7 cm in length.

Black Witch moth larva - Ascalapha odorata - wiki

‘BAD LUCK & TROUBLE’

The moth is a migratory species, flying from (roughly speaking) South America as far north as Florida and Texas. The worst luck is believed to come from having one flutter into your house. Once inside, it will either bring bad luck to the house – or if there is already misfortune there, it will make it even worse. There are variations on this belief – e.g. that the more corners of a room the moth visits, the more doomed the household.

Black Witch moths Ascalapha odorata (Julia Gotz)

ANY GOOD NEWS ABOUT THIS CREATURE, OR ALL GLOOM & DOOM?

Fortunately yes, and it’s high time to dispel the gloom hereabouts. In some places (e.g. Hawaii), it is believed that when a loved one has died and an Ascalapha odorata is seen soon after, it is the person’s soul returning to say farewell. 

More promisingly still, in the Bahamas and wider Caribbean a far more positive and practical attitude is shown. If a Money Moth (or Money Bat) lands on you, you will receive some money. Or so it is said. I have never heard of this happening, but at least it is an optimistic approach to the moth. And Texas, thinking big, takes this several steps further to the prediction that you will win the lottery (I have a feeling this is a very modern theory).

WHY ARE YOU SCARING US WITH THIS THING?

Because at one time I had never heard of these moths, let alone seen one. Then one balmy Bahamian evening, at dusk, someone pointed out a large dark smudge on the door-frame. I only had a phone, and I had to use the flash. Here is the moth, with its evil little eyes shining in the bright light. Luckily, it was outside and not inside the building, which I hope diluted the malevolence radiation level. I didn’t realise the significance of the moth and the implications at the time of course, until I’d looked it up in Sibley’s indispensable ‘Compendium of Evil Moths‘**). It’s a poor photo, but it was useful for ID and I feel that taking a quick shot helped to ward off the worst of any unpleasantness. Though I remember that I fished very badly (even by my low standards and expectations) the following day…

        

CULTURAL SIGNIFICANCE IN LITERATURE

Remember Silence of the Lambs? Well in the book, pupae of the Black Witch moth were placed in the mouths of victims by serial killer ‘Buffalo Bill’ as his calling card – though for the film, the moth species was changed to a Death’s-head Hawkmoth, as featured on the poster.

You can read about Hannibal Lecter’s link to moths, and learn how for the film the pupae were made from sweets (Gummi Bears ™) so as to be harmless if swallowed, HERE

SO – BE HONEST – ARE THEY HARMFUL IN ANY WAY AND / OR WILL ONE MAKE ME RICH?

No

BELLA MOTHS: COLOURFUL, POISONOUS & PROMISCUOUS


Day-flying_Bella_Moth_(Utetheisa_ornatrix) on Rattlebox Blossom (Bob Peterson, Florida)

BELLA MOTHS: COLOURFUL, POISONOUS & PROMISCUOUS

The BELLA MOTH Utetheisa ornatrix is also known as the ‘ornate moth’ or ‘rattlebox moth’ (a tall spiky plant of the species Crotalaria). The italianate ‘bella’ signifies beauty and all the many synonyms for it. These moths come in colours ranging from pink to red or orange, and yellow to white. Some have vivid coloration, others are less bright. Their black dot markings are broadly similar. Moths are often thought of as creatures of the night, so daytime would not be an auspicious time for moth-hunting. In fact there are many moth species that are active during the day (‘diurnal’), and the Bella Moth is one of them. 

Bella Moth, Neem Farm, Abaco (Keith Salvesen) 1

DEFENSIVE WARNINGS

The bright coloration is (as in many species) nature’s way of saying ‘leave me alone’ and in particular, ‘I am very unpleasant to eat’. It is called APOSEMATISM.  The unpleasantness derives from toxins of the plants they feed on. This starts at the larval stage. The larvae feed on plants that contain poisonous alkaloids – in particular the yellow rattlebox plant – rendering them extremely unpalatable. both as larvae and adults. Bella adults in need of an alkaloid boost may cannibalise moth eggs, pupae or larvae to counter a deficiency. 

Ornate_moth_(Utetheisa_ornatrix) Charles J Sharp wiki

BELLA MOTH SEX LIVES: ‘IT’S COMPLICATED’

  • Sexual encounters are dictated by females, who compete with other females for males
  • Females seeking to mate always outnumber available males
  • A female bella will release powerful pheromones at dusk to lure males
  • Related females uniquely engage in collective pheromone release
  • This is termed “female pheromonal chorusing”, an irresistible draw for the males
  • Several males will give the female chemical ‘nuptial gifts’ of both poison and sperm
  • The female chooses the best of her various suitors and copulates with 4 or 5 of them
  • The whole process of multiple copulation may take up to 12 hours
  • In some way I don’t understand, she is then able to select her preferred sperm provider
  • The sperm of the other males is rejected and they go away disappointed
  • Humans: do not try any of this, whether at home, in the office, in public, or when driving

GULL-BILLED TERNS ON ABACO, BAHAMAS


Gull-billed Tern, Abaco (Alex Hughes) 01

GULL-BILLED TERNS ON ABACO

The gull-billed tern Gelochelidon nilotica had a name upgrade from Sterna nilotica some years ago, and was awarded the honour of its own genus. 

Gull-billed Tern, Abaco (Alex Hughes) 04

Let’s be clear at the outset: there’s no such thing as a tern-billed gull. Which fortunately lessens the scope for species confusion. 

Gull-billed Tern, Abaco (Alex Hughes) 05

There are 12 species of tern recorded for Abaco. Only one, the royal tern, is a permanent resident. There is one winter resident, the Forster’s tern and there a 6 summer resident terns of varying degrees of commonness. The other 4 are transient or vagrant, and probably definitely not worth making a special trip to Abaco to find. The G-BT is designated SB3, a summer breeding resident that is generally uncommon, though may be more common in particular areas.

The bird gets its name from it short, thick gull-like bill. It’s quite large in tern terms, with a wingspan that may reach 3 foot. They lose their smart black caps in winter.

Gull-billed Tern, Abaco (Alex Hughes) 06

There are 6 species of G-BT worldwide, and it is found in every continent. While many terns plunge-dive for fish, the G-BT mostly feeds on insects in flight, and will also go after birds eggs and chicks. Small mammals and amphibians are also on the menu. The header image shows a G-BT with a small crab. I always imagined that they must eat fish. Surely they do? But I have looked at dozens of images online to find one noshing on a fish, with no success.

‘SEXING THE HUMMER’: A GENDER GUIDE TO ABACO’S HUMMINGBIRDS


 ‘SEXING THE HUMMER’
A GENDER GUIDE TO ABACO’S HUMMINGBIRDS

The drastic effects of Hurricane Dorian on Abaco’s birdlife continue, with recent reports suggesting that all species remain affected, and some severely so. However there are signs of a slow improvement, and this good news includes the two hummingbird species, the endemic Bahama Woodstar and the Cuban Emerald. A couple of recent posts on FB indicate that sightings of both these species have been a very welcome surprise. So, a good time to write about them and to show their beauty.

Cuban Emerald (male) Abaco (Charlie Skinner)

The subject matter of this post is not as indelicate as the title might imply; nor is it a ‘hands-on’ practical guide for intimate examinations of tiny birds. In particular it does not publicise some recently discovered louche activity involving unfeasibly large motor vehicles. It’s all about plumage and recognition. And there are only two species – and two genders for each one – to wrestle with. So here are the adult male and female Bahama Woodstars and Cuban Emeralds in all their glory…

WTF? (WHAT’S THAT FISH?): THE FROGFISH


Frogfish (Adam Rees, Scuba Works)

WTF? (WHAT’S THAT FISH?): THE FROGFISH

I have just been lightly involved in a long online thread showcasing the weirdest / most science fiction-y creatures around the world. Trust me, there are plenty. There were quite a few duplications. My own contribution was the frogfish, which no one else had nominated. They are so special – and so weird – that I am reposting my article about them. Don’t miss the last video!

frogfish-anglerfisch

This ‘WTF?’ series started with a relatively conventional species, the REMORA. It has been getting progressively more bizarre. We moved onto an omnium gatherum of WEIRDO FISHES, then the remarkable LETTUCE SEA SLUG, and most recently the BATFISH. Time to ramp up the stakes: with many thanks to scuba expert Adam Rees for use permission for his terrific photos, I present… the FROGFISH.

Frogfish (Adam Rees, Scuba Works)

The frogfish is a kind of anglerfish found in almost all tropical and subtropical oceans and seas. There are about 50 different species worldwide, covering an astonishing range of strange appearances. They generally live on the sea floor around coral or rock reefs. In size they vary from tiny to about 15 inches long – although ‘long’ is a flexible concept because they are to an extent shape-changers in height and width.Frogfish (Adam Rees Scuba Works)

FROGFISH SUPERPOWERS YOU MAY WISH TO HAVE

  • INVISIBILITY CLOAK . Frogfish are masters of disguise and camouflage. This enables them to catch their prey with minimal effort and also to avoid predators. Their camouflage methods – broadly known as ‘aggressive mimicry’ – include
    • Ability to change colour for days or even weeks to mimic their surroundings
    • Getting covered in algae and other organic matter that matches their habitat or
    • Looking inherently like a plump rock or in some cases, plant

Fear for the life of the spider crabFrogfish (Adam Rees, Scuba Works)

  • IRRESISTIBLE ATTRACTION
    • A sort of frontal dorsal fin called an illicium to which is attached a
    • Lure called an esca which may mimic a worm, shrimp or small fish etc and which is
    • Retractable in many species and
    • Regenerates if it gets mislaid

The ‘dollop of cream’ thing is the esca. Note the characteristic large mouthFrogfish (Adam Rees, Scuba Works)

Spot the escaFrogfish (wiki)

  • BUOYANCY CONTROL & SHAPE-SHIFTING
    • Most frogfish have a ‘gas bladder’ to control their buoyancy.
    • Some species can change shape or even inflate themselves by sucking in quantities of water in a so-called defensive ‘threat display’.

Frogfish (Adam Rees Scuba Works) Frogfish (Adam Rees Scuba Works)

HOW DO FROGFISH REPRODUCE? 

Although not conventionally attractive creatures, frogfish clearly manage to reproduce. Little is known about the techniques in the wild, but one is probably ‘with care’, especially for a male frogfish who may not survive for long if he hangs around after fertilisation has taken place. It has been noted that females tend to select far smaller males to fertilise their huge numbers of eggs, perhaps for that very reason.

Frogfish (Adam Rees, Scuba Works)

FROGFISH FEEDING SKILLS – GOOD OR BAD?

When deploying the lure, potential prey that comes too close to that wide mouth stands no chance. A frogfish will strike in a fraction of a second. Frogfishes have voracious appetites for crustaceans, other fish, and even each other. I can do no better than borrow this vivid description of a feeding frogfish:

“When potential prey is first spotted, the frogfish follows it with its eyes. Then, when it approaches within roughly seven body-lengths, the frogfish begins to move its illicium in such a way that the esca mimics the motions of the animal it resembles. As the prey approaches, the frogfish slowly moves to prepare for its attack; sometimes this involves approaching the prey or “stalking” while sometimes it is simply adjusting its mouth angle. The catch itself is made by the sudden opening of the jaws, which enlarges the volume of the mouth cavity up to twelve-fold, pulling the prey into the mouth along with water. The attack can be as fast as 6 milliseconds. The water flows out through the gills, while the prey is swallowed and the oesophagus closed with a special muscle to keep the victim from escaping. In addition to expanding their mouths, frogfish can also expand their stomachs to swallow animals up to twice their size.

images

HOW DO FROGFISHES GET AROUND? SWIM? WALK? CRAWL?

Frogfishes do not in fact move around a great deal. Using their camo advantages, they prefer to lie on the sea floor and wait for prey to come to them. As mentioned in the quote above, they may slowly approach prey using their pectoral and pelvic fins to “walk” along the sea bottom. They can swim using their tail fin (or in some species by simple ‘jet propulsion’ by forcing water out of their gills) but rarely do so – they don’t feed on the move, and they are adapted to the sea floor environment where they food is readily available. However their “walking” ability is limited to short distances.

frogfish-anglerfisch

DO FROGFISH HAVE OTHER COLOUR SCHEMES?

Indeed they do. In stark contrast to the camo species, some frogfishes are highlighter bright. Here are two of my favourite photos by Adam that show this clearly. I’ve no idea if these are a male and female. I suspect they are different species. I think the brown one is a striated frogfish and the other is… a yellow frogfish. Some people keep these creatures in  aquaria, but apparently it is impossible to sex them, and they have to be kept on their own for everyone’s peace of mind…

To read more about frogfishes and for some fabulous photos I highly recommend the website FROGFISH.CH You can reach the main page(s) but the link seem to be broken so I have not been able to contact Teresa Zubi, whose site it is. She clearly has a sense of humour and uses a neat pair of gifs which I hope she won’t mind my using…

Few birds radiate Yuletide vibes better than Painted Buntings, with their perfect festive colours. Here is a seasonal flock of them to enjoy. A very happy Christmas to those who kindly continue to visit Rolling Harbour, despite the unavoidable absence from the Bahamas of the Harbourmaster.

GREAT EGRETS: NOBLE (YET MISNAMED) HERONS


Great Egret, Bahamas (Nina Henry)

GREAT EGRETS: NOBLE (YET MISNAMED) HERONS

The Great Egret is actually a heron rather than an egret. It’s a Great Heron. All egrets are members of the heron family Ardeidae, but the converse is not true. As long ago as 1758, Linnaeus awarded the bird the binomial name Ardea alba i.e. ‘Heron white‘. Why it should have been so hard to stick to that authoritative nomenclature, I can’t imagine. Perhaps in time all heron and egret species became so hopelessly confusing for people that it ceased to matter much what they were called.

Great Egret, Bahamas (Nina Henry)

Maybe it was that type of carelessness that led to people from the mid-c19 onwards eyeing up GREGs as a source of hat feathers and other decorative necessities. As with flamingos and many other beautiful avian species, mankind’s millinery and other fashion needs were satisfied at the expense of gorgeous plumage. Actually, at the cost of the birds’ lives: they were simply shot in huge numbers. 

Great Egret, Bahamas (Nina Henry)

Healthy populations were decimated; for some species they never recovered. For others, the great egret among them, the passage of time and the passing of fashions – backed in many cases with conservation programs – have successfully restored the populations. In 1953 the National Audubon Society, which was formed at least in part to discourage the killing of birds for their feathers, took a decisive step in the cause of the great egret by making the bird the emblem of the organisation.

The WEST INDIAN WOODPECKER Melanerpes superciliaris is one of Abaco’s specialist birds. Islanders and regular visitors will be familiar with the sight – and indeed the raucous sound – of these beautiful birds. They are commonly found throughout Abaco and the cays. Possibly their rarity across the wider Bahamas is underestimated. The only other island where these birds are found is San Salvador. Formerly resident on Grand Bahama, they are believed to be extirpated there. Abaco is very fortunate to enjoy their noisy company.

The white-cheeked (‘Bahama’) pintail Anas bahamensis (aka ‘Bahama duck’) is everyone’s favourite dabbling duck. Or at least it ought to be. And when there are ducklings swimming with the adults, there is no emoticon yet devised that will convey the extremes of cuteness achieved.

“I GET AROUND”: PIPING PLOVER TUNA’S GUEST POST (3)

“I GET AROUND”: PIPING PLOVER TUNA’S GUEST POST (3)

ABACO PIPING PLOVER WATCH was an amateur ‘citizen science’ conservation program to help investigate the winter season migrations of a tiny shore bird. It started in August 2015 and ended with Hurricane Dorian Sept 1st 2019. TUNA was the first banded bird we found, a summer chick that had completed a 1000+ mile flight when aged about 3 months. During the season, Tuna’s life on Abaco was monitored, in particular by Rhonda Pearce who bonded with the little bird and took lots of photos. Tuna asked, in a whimsical way, if I would make space for a Guest Post. I recently re-posted the first HERE . This is the third instalment.

Hi again, readers of Mr Harbour’s blog. Tuna still here. This is part 3 of my diary.  I’m 4½ months old now, and getting on famously here on Abaco. Especially now the big wind and waves have gone away [Hurricane Joaquin – ed]. Someone called me ‘Abaco’s favourite plover’, which really fluffed up my feathers. I’ve started to explore a bit and meet more birds just like me*. Turns out they are all Travellers from the North too – what are the chances? [in winter, 100% – ed]

*How do I know what I look like? Well it’s easy. When I am chomping meat strings in the sunshine on the edge of the water, there’s a picture of me in the water doing the exactly same thing at the same time only upside down. Like these two friends of mine here.

PiPl 5x WB 23.10.15 min

I do a lot of running about on the beach. Back and forth. Up and down. Into the water and out again. It’s a busy life. And I’ve only got little legs. In case anyone worries that Michelle’s 4 smart rings hurt me or get in the way, I never feel them. They are just a part of who I have always been since she picked me up the day after I cracked out and added the bird-bling.

Piping Plover Tuna. Abaco. Rhonda Pearce 2

I’ve met lots of birds that are different from me, too. Some live here all the time, others are Travellers from the North as well. I’m relying on Mr RH here to show you some of the guys I hang out with these days. We all kind of mix up and if you don’t try to find meat strings where the bigger birds want to find them, it’s very friendly. Actually they are all bigger than me!

I’ve made my first trip to a different beach. I decided to fly round and explore, and I saw lots more sand so I flew there and stayed a couple of days. Like a little holiday. A nice man [monitor Keith Kemp] saw me there and told Mr RH about my coloured bands. That’s how he knew I’d moved and he told my friend Rhonda so she didn’t go looking for me on my home beach and get worried that I wasn’t there. Then I flew back there after a couple of days and Rhonda found me there again yesterday.

I’ve got a new game I’ve been playing when Rhonda comes to see me. She sits down on the beach and puts shells all round her in the sand. So I come over and have a look at them (once I pecked the cloth thing she sits on. Urrch! It wasn’t food). Then she uses that thing that makes a plover noise [the focus sound on her camera – ed] and I put my head on one side to listen. Piping Plover Tuna. Abaco. Rhonda PearcePiping Plover Tuna. Abaco.

There’s another reason I put my head on one side. Sometimes really really big birds fly over the beach. Huge dark ones. I like to keep an eye on them. I think they may be trouble. So I put my head on one side so I know exactly where they are in the sky until I feel safe.

This is me back on my beach after my trip. Green on Blue (L); Black on Grey (R) = TUNAPiping Plover Tuna. Abaco. Rhonda Pearce 1

This is a New Friend on my beach, one of 3. They don’t have smart legs  but they are Travellers from the North like me. In this game I lie low in a hole in the sand and my NF rushes at me kicking sand up like a crazy bird. Fun, huh?Piping Plover Tuna. Abaco. Rhonda Pearce 1

More news from me soon. Cheeps from Tuna.

NOTE If you ever wondered why birds are banded and what on earth use it is, the answer is in this story. Banding & tagging enables detailed research at both ends of the migration which in turn enables protection of the species and conservation of threatened habitats. There are only 8000 PIPL left. Degradation of the breeding grounds or the overwintering grounds – let alone both – may result in extinction. This seems to have been a good summer for the piping plover; let’s hope the winter treats them well so that this summer’s chicks like Tuna will be able to breed safely next year.

This Diary extract shows how an individual banded bird’s movements can be monitored within its chosen area, so that a picture can be formed of its habitat choices, location changes, and range.

“THEY FOUND MY MUM ON ANDROS”: PIPING PLOVER TUNA’S GUEST POST (2)

ABACO PIPING PLOVER WATCH was an amateur ‘citizen science’ conservation program to help investigate the winter season migrations of a tiny shore bird. It started in August 2015 and ended with Hurricane Dorian Sept 1st 2019. TUNA was the first banded bird we found, a summer chick that had completed a 1000+ mile flight when aged about 3 months. During the season, Tuna’s life on Abaco was monitored, in particular by Rhonda Pearce who bonded with the little bird and took lots of photos. Tuna asked, in a whimsical way, if I would make space for a Guest Post. I recently re-posted the first HERE . This is the second instalment.

Hello again, readers of Mr Harbour’s blog. My name is Tuna. This is the second part of my diary. Last time he called it an ‘autobiography’, but that was a bit pompous of him, I think. It’s 4 months now since I cracked out and after my long trip from that place [the Holgate Unit of the Edwin B Forsythe National Wildlife Refuge, New Jersey – ed.], I’m having a good time on Abaco – see my picture above. Michelle, who put my 4 cool rings on when I was one day old, would be proud of me I think.

Since my last post some things have been happening to me. There I was, safely on my nice beach [Watching Bay, Cherokee Sound – map below] when the wind started to get scary and the sea kept coming further up the beach. And a whole lot more splashy [it was Hurricane Joaquin – ed.]. So I just hid at the back of the beach until it got better again. I knew if that nice lady came back to see me it would mean I could come out again. And she did. So I did. I showed her my bands so she’d know it was me. Green on blue; black on gray. That’s me and no other bird.

Mr Harbour wrote and told people about how I was ok after a big storm. He said:

“TUNA THE PIPL: UNRUFFLED BY HURRICANE JOAQUIN” Oct 3. Despite big seas & high winds reaching N Baha on the fringes of the hurricane, Tuna has returned safely to Watching Bay. Photos clearly showing bands. π Rhonda Pearce”

A lot of people [c2000] read about this and Michelle said “yay!!! go tuna!!!”, so maybe people had been a bit worried about me. People passed the story round. What ever a ‘Chorlito Valiente’ is, it sounds good and I’m glad to be one. I’m doing just fine, thank you…

Since then I had THE BEST NEWS. My mum Paula has been found! She’s gone to a different beach that’s not very close to here [Joulter Cays, Andros – 100 miles]. She’s got a different leg thing called a “UR Green Flag PE2” and somebody saw her! I’m so excited (and I hope my dad Ross is safe too). She was in a crowd of 32 other birds just like her, and a lot of other birds friends too.

I hope if I get that feeling again that I need to fly a long way, my mum gets it too. And my dad. Then we might all end up on the same beach where I cracked out! But I’m planning to stay on my own beach for now. More news from me soon. Cheeps from Tuna.

This Diary extract shows that not only can an individual banded bird’s migration movements be monitored, but also (with a bit of luck) a parent or sibling – even though they may chose to overwinter in quite different places. It is of particular significance if they then return to the same area in summer for breeding.

THREE ‘HALLOWEEN-COLOURED’ BIRDS ON ABACO, BAHAMAS


6292695150_32bb41d043

THREE ‘HALLOWEEN-COLOURED’ BIRDS ON ABACO

Black and orange seem to have become – perhaps always have been – the colours most associated with Halloween. At one time in its history this annual fright-fest was simply ‘Holy Evening’, the one that preceded All Saints’ Day. It was once one of the most significant festivals in the religious calendar. Now it is all broomsticks, spiders, cobwebs, huge grinning fruit, and tiny sweets for small children.

As for the colour-scheme, I suppose black is for the witches, their cats, bats and the night; and orange for fire and pumpkins. Ghosts, being invisible, are beyond the scope of this post. In nature, surprisingly few creatures and plants have a predominantly black and orange livery. Some birds. A salamander of two. A few flowers.  The odd fish. And of course the monarch butterfly.

I spent a small amount of time checking which birds found on Abaco are true Halloween species, though obviously none of my go-to bird books had a ‘scare factor 50’ species entry in the index. I had to allow for some white markings, reasoning that white is not a colour but rather an absence of colour… That left 3 qualifying species (and even then some troublemakers might argue that the precise borderline between orange and yellow is debatable…) and one failed candidate, included only because of the spectacular photograph.

AMERICAN REDSTART

The Redstart Setophaga ruticilla is a species of warbler and a common winter resident on Abaco. They are mostly seen in the coppice and in gardens. They’ll be around right now – watch out for them fanning their tails. The males are black with orange markings; the females have yellow markings instead of orange and are therefore ineligible for this post. Sorry.

BALTIMORE ORIOLE

These Orioles Icterus galbula are rather less common winter visitors. A few are reported most years, but you’d probably only come across one by accident. Many are completely black and orange apart from white wing bars. However, there’s no doubt that others are more of a yellowy-orange.

WESTERN SPINDALIS

The handsome, colourful Spindalis zena is one of my favourite birds. Top five. The spindalis is a common permanent resident, and I am determined to make it qualify as a Halloween bird even though (arguably) plenty of its surface area is neither black nor orange. Apologies to purists.

BOBOLINK (disallowed)

A possible Halloween candidate is the bobolink Dolichonyx oryzivorus. which is a transient species found from time to time on Abaco as they migrate from north to south (fall) and back again (spring).  Disqualified because it spends so little time in Abaco; and because even my rather lax approach to categorisation recognises that the ‘orange’ is not very orange; and there’s not a great deal of it.

BLACK-FACED GRASSQUITS ON ABACO, BAHAMAS


Black-faced Grassquit male, Abaco (Alex Hughes)

BLACK-FACED GRASSQUITS ON ABACO, BAHAMAS

A while back, Black-faced Grassquits Tiaris bicolor were honoured by the American Ornithological Union with a classification change from emberizid to tanager. For the reasons that follow, the species regarded this both as scientific promotion and as merited status elevation. I invited an authoritative Spokesquit to explain why.

*******************

Hi, human friends, I’m a black-faced grassquit  and I have a couple of observations to make on behalf of BFGs, if I may. First, we seem to be universally described by you as ‘common’, whereas we are actually quite refined in our behaviour. Secondly, the words most used to portray us are ‘dull’ and ‘drab’. And ‘stubby’. Well, excuse me… I – we – ask you to give us a second look. Maybe check out these images for a start.

black-faced-grassquit-adult-male-eating-berry-abaco-bahamas-tom-sheleyblack-faced-grassquit-foraging-berry-2-abaco-bahamas-tom-sheley

Unsurprisingly we were very excited when the perceptive classifications committee of the American Ornithological Union gave us an upgrade. That’s the way we saw it anyway. For many years we were classified under the heading emberizidae. 

Black-faced Grassquit male, Abaco (Bruce Hallett)Black-faced Grassquit, Abaco (Tom Reed)

We kept company with some buddies like the handsome Greater Antillean Bullfinches, but also with a lot of New World sparrows, with whom we (frankly) never felt entirely comfortable. Annoyingly chirpy, for a start.

Black-faced Grassquit - Treasure Cay, Abaco (Becky Marvil)Black-faced Grassquit male, Abaco (Peter Mantle)

And so we officially became a type of tanager. They even reckon (rather late in the day, in my view) that we are closely related to Darwin’s finches. So, we are “common”, huh? Now we get to be with other birds that are dome-nesters like us. And how about this – we’ll be in the same list as some really cool birds…

Black-faced Grassquit male, Abaco (Gerlinde Taurer)

How’s this for a colourful gang to be joining: scarlet tanager, summer tanager, rose-breasted grosbeak, indigo bunting, painted bunting – these are our new cousins. BFGs “dull” and “drab”? I don’t think so.

6 UNDULL FACTS ABOUT BFGS

  • Make grassy dome-nests (like Bananaquits) and line them with soft grasses
  • Both sexes build the nest together
  • Both share egg-sitting duties and later chick-feeding & maintenance
  • Though quite gregarious by day, for some reason they tend to roost alone
  • They have a short ‘display’ flight with vibrating wings and a strange buzzing call
  • Otherwise, their flight is ‘weak, bouncy & fluttering’ (Whatbird assessment)
