PAINTED BUNTING
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.
CLAPPER RAILS Rallus crepitans are elusive birds of mangrove swamp and marsh, more frequently heard than seen. They tend to lurk around in foliage and are easy to overlook. They are creatures of the margins rather than open ground. You may come across one foraging secretively, beak-deep in the mud.
Tom Sheley’s wonderful photos featured here of a preening clapper rail were taken during our backcountry explorations to locate and photograph species for BIRDS OF ABACO. By being both patient and an early riser, Tom managed to capture this fine bird engaging in some quality grooming. The one below is ‘vocalising’ – known in rails as ‘rousing’ – in mid-preen.
Clapper rails are capable of swimming and even of flying if they choose to. However the most likely activities you are likely to observe will be skulking, picking their way through marginal vegetation, or (if you are lucky) doing some beak-deep foraging in the mud. Occasionally they run, a process that looks endearingly comical and which possibly gives rise to their name.
It almost goes without saying nowadays, but the biggest threat to these rather charming inoffensive birds is habitat loss. Which is to say, mankind either directly or indirectly. Drive the bulldozers through the mangroves and marshland of sub-tropical coastal areas, chuck down a few acres of concrete… and the clappers will very soon become clapped out. As they will if the climate we are unarguably changing ruins their unobtrusive lives.
COMPULSORY LINGUISTIC STUDY
When I last wrote about this species its binomial name was Rallus longirostris ie simply ‘long-beaked rail’. Since then the increasingly frenetic annual turmoil of official AOU shuffling species about and messing with their names has resulted in the clapper rail being re-designated Rallus crepitans or ‘rattling / rustling rail’, I assume from the call. There are other rail-name innovations that, reading about them just now, made me crack open a beer instead of wanting to tell you about them.
OPTIONAL LINGUISTIC DIVERSION
“TO RUN LIKE THE CLAPPERS”. This phrase seems to be fairly recent, most likely originating as military (?Air Force) slang early in WW2 or possibly from earlier conflicts. Some suggest it is a rhyming slang bowdlerisation of ‘run like hell’ with ‘clapper(s)’ standing for ‘bell’, along the lines of the Cockney “I bought a brand new whistle” (whistle and flute = suit). Almost all plausible explanations relate to bells, and some argue that it simply reflects the rapid speed of the clapper of a vigorously rung handbell. This derivation as a link to the bird seems tenuous at best.

PAINTED BUNTING
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!
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.

The two wonderful photos below are by Tom Sheley, a major photographic contributor to THE BIRDS OF ABACO. They were actually taken in Texas, but I include them because of Tom’s strong connection with the birdlife of Abaco; and also because they are fantastic shots…
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.

I see it is ‘literally’** years since I last wrote about these lovely, accessible birds, the only permanent resident breeding thrush species on Abaco (out of 8). The post – OL’ RED-EYES IS BACK – featured mainly my own photos, plus one by Mrs RH. With a whole lot of more recent photos, it’s time to revisit these cheery birds. I promised something brighter after two rather sombre shearwater die-off posts – (incidentally, a far wider problem than just in the Bahamas, including NC & Cape May). Here it is.
A RED-LEGGED, RED-EYED GALLERY
Many of the birds shown here were photographed in or around the grounds of Delphi. More recently, they have to an extent been displaced by red-winged blackbirds which are of course very fine birds but in large numbers sound (may I say this? Is this just me?) quite irritating after a while. Whereas the thrush of course has a sweet and melodious song, like this (my own recording – turn up the vol):
Mr & Mrs Harbour’s Handiwork at Delphi
As I may have mentioned before (impatient reader: ‘yes, yes, you did’), the eyes of the RLT are at least as prominent a feature as their legs. Lots of birds have red legs. Very few have such remarkable bright, fiery eye-rings, even in a youngster.
This photo from birdman Tom Sheley is my favourite – a perfect composition
** This means it really is literally years (4), not in the modern modified sense of ‘not actually literally’, as in “I am literally dying of hunger”. Unless you are exceptionally unfortunate, while you have the breath to say you are, you are literally not doing so…
FUN FACT
There is quite literally no song since 1950 with the word ‘thrush’ in the title. Hard to fathom why… One or two songs have a thrush buried away in the lyrics somewhere. Blackbirds have done rather better in this respect…

YELLOW BIRDS ON ABACO: A ‘TWIXTMAS’ COLOUR SCHEME
Red. Green. A splash of blue. The shimmer of gold and silver. Those Christmas colours are so passé. OVAH! So ‘last year’ (or very nearly). In the hope and expectation that people are not too bilious from Xmas Xcess, or too jaundiced by seasonal overload, I feel it’s time to change the colour scheme. Let’s go for bright yellow. Specifically, a mix of endemic Bahama Yellowthroats and Common Yellowthroats. I love these cheerful little birds, and the challenge of trying to lure them into the open with my rather unconvincing approximations of their ‘wichity’ call. Such sunny little creatures, and always such a joy to watch.

PAINTED BUNTING
It’s hard to imagine a more Christmasy little bird than the Painted Bunting. Bright blue, red, green primary colours make for a spectacular small bird to grace any garden or feeder. There are other bunting species and close relations – e.g. grosbeaks – on Abaco. A common factor is the little fat beak and voracious seed greed…

In normal parlance a ‘wild-goose chase’ is of course a futile search or a useless pursuit**. However, I bring you news of a successful chase after wild geese on Abaco – indeed the bagging of all four of the goose species recorded for Abaco. All are classed as winter residents, with rarity rated from ‘uncommon’ to ‘good grief, that’s a first’. So I present them in the order of relative excitingness…
GREATER WHITE-FRONTED GOOSE
This fine bird caused a bit of a stir. Not only was it a first for Abaco, the species had never before been recorded in the Bahamas. In February 2012, the goose was found at the pond at hole #11 on the Treasure Cay golf course, presumably having been blown off its normal migration route. This range map shows just how far.
Erik Gauger managed to get the close shot above; Uli Nowlan got a few from further away, including a swimming view. I know of no other photographers of the bird (though Woody Bracey published a report about it). If there are any, I’d be pleased to hear about their photos – indeed to add them!
ROSS’S GOOSE
Equally rare on Abaco is the Ross’s Goose. Far to the east of its normal migration route, one found its way to the Goose Magnet of Treasure Cay. The range map shows the very clear routes this species chooses for its migration.
CANADA GOOSE
Another anserine visitor to Abaco – slightly more frequent than the two species above – is the Canada Goose. Again, Treasure Cay golf course exerted its powerful pull to drag this one from its usual route, where it happily took up residence. As you can see from the range map below, these geese have a widespread habitat and spend at least some of the year not that far from northern Bahamas, so it is less surprising that they turn up on Abaco from time to time.
SNOW GOOSE
Although a relatively unusual winter visitor to Abaco, and a good ‘get’ for any birder’s checklist, I was surprised to find that the snow goose is classed as more common than the Canada goose. Its usual habitat is further away; and its summer breeding territory is very far north. Again, when a snow goose drifts eastwards, Treasure Cay is its spiritual home…
Why geese are not found elsewhere on Abaco other than Treasure Cay is a mystery. The TC golf course water is presumably fresh, whereas other locations – Gilpin Pond on South Abaco for example, or the neglected ponds of the defunct ‘Different of Abaco’ – are distinctly brackish. Perhaps that makes all the difference.
Abaco’s Four Geese Species
**WILD-GOOSE CHASE The etymology of the phrase is medieval, referring to a horse race in which pursuers try to follow an erratic ‘wild goose’ leader. Shakespeare used the term in Romeo and Juliet, with Mercutio saying “Nay, if our wits run the wild-goose chase, I am done; for thou hast more of the wild goose in one of thy wits than, I am sure, I have in my whole five.” Which was quite a good, if cumbersome, insult.

Following my last gloomy post about the widely-reported die-off of the poor, exhausted migratory great shearwaters, let’s turn with relief to a cheerful bird known to all and admired in coppice and garden: the Greater Antillean Bullfinch Loxigilla violacea. These pretty birds are easy to find and to identify. They love feeders, and they are responsive to ‘pishing’, that irritating (?) noise that birders make to unseen avians in the coppice to persuade them to reveal themselves. Adult males are black with bright red accessories (hence “police bird”); females are paler with orangey accessories; and juveniles look a bit scruffy and patchy. Here’s a GAB gallery to enjoy.

The KILLDEER Charadrius vociferus is a fairly common winter resident plover on Abaco. They can often be found on the Delphi beach, and the lovely beach at Casuarina is another place to spot them. They can easily be distinguished from other plover species, being the only ones with two black frontal bands – see above and below. The lower picture, you’ll be relieved to hear, is not the fabled ‘legless killdeer’, but is simply having a little rest on a nice warm wall.
The killdeer’s name is a bit of a puzzle, frankly. The Latin term Charadrius vociferus basically means “shouty plover”, but it’s a long way from that to “killdeer”. This is another one of those bird names that are allegedly onomatopoeic – and thankfully it has nothing whatsoever to do with savage behaviour involving Bambi and his ilk (or elk, even). Supposedly the killdeer call is “Kill…Deer”, in the same way as the bobwhite calls an interrogative “Bob…White?”.
Consulting some random authorities reveals divergence of opinion on the issue, with definite bet-hedging between ‘kill-dee’ variations and ‘dee dee dees’. Except for Messrs Flieg & Sanders who opine (rudely) ‘the shrill, loud, monotonous call resembles its name’. Yet while I completely get the ‘Bob…White?’ thing, I’m not so sure with the killdeer. Were I a little killdeer, it’s a name I’d like to have anyway. Respect! But what do these sound like to you?

I’ve mentioned the distinctive double black breast-bands that distinguish the killdeer from its brother plovers. These can be seen at quite a distance, as this shot on the Delphi beach by Mrs RH shows (the tracks are from Smithy’s seaweed-clearing tractor).
The babies are, like all plover chicks, totes irresistibz munchkins
And like other plovers, a killdeer will defend its nest and young with a broken wing display to distract predators, lurching pathetically across the sand, moving ever further away from the nest.
I think we can safely conclude that, while the bird doesn’t quite live up to the cervidae-cidal tendencies suggested by its name, nor even sound particularly as though it is saying “killdeer”, it is a very attractive plover to have around whatever the heck its call may resemble.

** Got it now: The very excellent Mike Bizeau, whose on his wonderful NATUREHASNOBOSS website posts a single daily image. Many are birds, some are landscapes, some are other things that have caught his eye. I get a daily email, and am invariably impressed by the quality of the images…
The Yellow-throated Warbler (Setophaga dominica) is a most helpful warbler, in that what you see is what you get. You needn’t go to embarrassing lengths to determine whether it has a Yellow Rump. It doesn’t make extravagant geographical claims like the Cape May, Kentucky, Tennessee, Nashville or Connecticut warblers. It doesn’t disguise its warblerdom with a confusing name like ‘American Redstart’ or ‘Ovenbird’. Nor with a weird warbler name that is completely obscure like the Prothonotary. It’s a winter resident only, so it won’t try to puzzle you in the summer. The males and females are roughly similar in appearance, unlike so many species. All-in-all, a most agreeable and obliging little bird. Here are a few to enjoy, before I spoil the magic slightly…
YTWs are quite pose-y birds, and tend to strike attitudes. One is the ‘head-in-the-air’, as below and further above. There’s the ‘butt-in-the-air’ too, immediately above (one of my favourite photos)
This shape is both characteristic and characterful. You might call it the ‘sag-in-the-middle’
This year I saw my first YTW in the Delphi Gardens, skulking around in a Gumbo Limbo tree. Having taken a number of rather poor shots – partly due to the intervention of branches, twigs, leaves, berries, shaky hands and so forth – I got some clearer shots at it, the two above and below being the best of an indifferent bunch.
Exactly a year ago, the ultimate, complete and utter Checklist of the birds of Abaco, compiled by Tony White with Woody Bracey, was published. It covers 4 pages of close print in THE BIRDS OF ABACO, and lists the 282 species recorded since 1950, including so-called ‘exotics’ but excluding so-called ‘pets’ (sadly your minah bird would not qualify). New sightings had been static since a BLACK-BROWED ALBATROSS had made an unheralded appearance out at sea. In the last year, 5 new species have been recorded. The links to them are listed below. That Checklist already needs an update!
The newest bird in town is the Pearly-eyed Thrasher (Margarops fuscatus). This is a bird in the family Mimidae, along with mockingbirds and the gray catbird. Until last November, no thrasher species had ever been recorded for Abaco. Then there was a sighting of a BROWN THRASHER. Just a few months later, its Pearly-eyed cousin has turned up right in the heart of Treasure Cay, seen by first by Erik Gauger and confirmed by Woody Bracey (each a contributor to THE BIRDS OF ABACO).
This thrasher species is found widely throughout the Caribbean, though with several varieties that are genetically distinct. In the Bahamas, they breed on some of the southern islands. They are known to overwinter on Eleuthera and Cat Island, but have not previously been recorded as far north as Abaco. This sighting is important in suggesting that the species may be beginning to extend its range, although it could of course simply be a one-off ‘vagrant’, as they are officially yet disrespectfully known.
Since the first sightings by Erik & Woody a couple of days ago, Woody has been out again with a camera seeking to obtain photographic evidence of the bird. Last night he sent me a snapshot taken in difficult circumstances – the bird was being hassled by a Eurasian Collared Dove (who should have known better, being a non-native species itself…). The pearly eye is quite clear, as is the speckled front and white end to the underside of the tail. If a clearer shot comes in, I’ll add it. So, TC-based birders, a Rolling Harbour Kalik challenge is on!
STOP PRESS Woody has sent a couple more photos of the PET taken right in the centre of Treasure Cay. Or perhaps there is a second one… and if so, different sexes… and if so, a nest, eggs, chicks, fledglings and in due course a new breeding species on Abaco…
STOP PRESS April 2015 Erik Gauger has now written up his account of his discovery of this new species for Abaco. You can read it HERE (scroll down to the second article on the page)
The other photos I have used are ‘open source’ for obvious reasons, and credited below as far as the information is available…

FEWER THAN 300 LEFT IN THE WORLD – AND ALL ON ANDROS
Having just posted about the endangered NASSAU GROUPER and its protection by the introduction of a 3-month closed season, it’s time to focus on a rare, beautiful and vulnerable bird, the Bahama Oriole (Icterus northropi). It is IUCN Red Listed as ‘Critically Endangered’. ENDEMIC to the Bahamas, this bird lived only on Abaco and Andros. Not any more. Now you’ll only find them on Andros, the species having been lost to Abaco in very recent memory. The 1990s, in fact. And on Andros, this lovely bird is now struggling against the threat of extinction and is found only in limited areas in very small numbers. The most optimistic population estimate I have found puts the total as fewer than 300 individuals… the consensus puts the likely total in the region of 250. 
THE SPECIES
In 2010, the Greater Antillean Oriole Icterus dominicensis was separated by the AMERICAN ORNOTHOLOGISTS’ UNION into 4 species, one being the Bahama Oriole. As the BNT wryly put it, “New species are always a source of excitement… but in this case the intrigue is overshadowed by a sense of alarm and urgency”. For by then this new species ‘in its own right’ was limited to certain parts of Andros, in small and diminishing numbers. It had already vanished from some areas – especially in North Andros – were it had formerly been abundant. The best estimates suggested 250 individual birds. 
WHEN & WHY DID THEY VANISH FROM ABACO?
This is a classic ‘riddle wrapped in a mystery inside an enigma’. Various sources I have looked at use a formula such as “…became extirpated from Abaco in the 1990s”, or “disappeared for unknown reasons in the 1990s”. I’ve found no clear clue as to the cause – nor even when the last sighting of an oriole on Abaco was made. I haven’t found a photo of one taken on Abaco, although to be fair the option of snapping everything with wings several times using a digital camera with a large chip didn’t exist then. In the next para a number of crucial factors in the more recent decline of the Andros population are given; but as far as I can determine, some at least did not apply in the 1990s, or certainly not to the same extent. Maybe it was a combination of a degree of habitat loss and the gradual decline of a small population that could not breed prolifically enough to sustain the future population **. 
THE MAIN CAUSES OF THE CRITICAL DECLINE ON ANDROS
Lethal Yellowing Disease of the coconut palm, prime nesting habitat for the oriole. In some areas on Andros (e.g. Staniard Creek), the palm has been all but wiped out.
The arrival and spread of the Shiny Cowbird Molothrus bonariensis, a brood parasite that lays its eggs in the nests of other bird species such as the yellow warbler, the black-whiskered vireo… and the oriole. The cowbird reached Andros in the mid-1990s. The first Abaco report that I have found is from 1999 (so presumably, as the oriole was already gone from the island by then, they were not a factor). The cowbird is a summer resident on Abaco, though still relatively uncommon; and its range continues to expand northwards. Some might argue that the cowbird should be discouraged from spreading on Abaco right now for the sake of the indigenous warbler and vireo populations – before it is too late.
Habitat loss / island development (although Birdlife International notes “…the planting of coconut palms in residential areas has allowed the species to spread into human settlements”). Other factors put forward include forestry work, forest fires, diseases, rodents and feral cats – problems that affect many other birds such as the Abaco parrot. 
The photo below is a pleasure to include in this post. It was taken earlier this year on Andros by Christopher Johnson of Nassau. And here’s the thing. He is 13, and an avid birder. I’m sure he likes his X-Box time, but he certainly knows plenty about birds too. He’s quick off the mark with offering IDs – correct ones – for birds online, and when he saw this bird he knew the significance of it and managed to get some good shots too. This is my favourite, the oriole ‘vocalising’. See below for its song. Here is Christopher’s brief but enthusiastic field report: “Awesome trip to Andros this past weekend! Was amazed to see the Bahama Oriole and its nest — feeling great”.

A GLIMMER OF HOPE?
In the same way that urgent conservation measures were put in place to halt and then reverse the critical decline of the Abaco parrot population, similar projects are in place for the Bahama Oriole on Andros. One proposal is to establish a ‘captive breeding’ program leading to reintroduction and reinforcement of the wild population. According to the American Bird Conservancy, this could even include reintroduction on Abaco… So perhaps in a decade or two, this fine bird will once again become firmly established as one of the birds of Abaco. 
As I said in my Nassau Grouper post, a country’s attitude can to a degree be gauged by the pride with which it features its wildlife and natural resources in its stamps (I used North Korea for adverse comparison). In 2009 The Bahamas Postal Service even issued a ‘Rare Birds’ set featuring the Bahama Oriole.. I rest my case.

WHO WAS THE EPONYMOUS MR NORTHROP?
The comprehensive answer is provided by the University of Glasgow Library Research Annexe in relation to a fine illustration from A Naturalist in the Bahamas (1910), reprinted in The Auk journal (below) at a time when Icterus northropi was still a mere subspecies: The yellow and black Bahama Oriole (Icterus Northropi) is a bird species unique to the Bahamas. The bird was named for American ornithologist and zoologist, John Isiah Northrop (1861–91); the illustration comes from an account of the trip Northrop and his botanist wife, Alice, took to the Bahamas in 1889 which was published in his memory: A Naturalist in the Bahamas: John I. Northrop, October 12 1861-June 25, 1891; a memorial volume (New York: Columbia University Press, 1910). It was edited and introduced by Henry Fairfield Osborn, professor of zoology at Columbia University where Northrop worked as a tutor and was killed in a laboratory explosion shortly (9 days) before the birth of his son John Howard Northrop (who became a Nobel prize-winning chemist). 
RELATED MATERIAL
“Rediscovering the Bahama Oriole” Erik Gauger, author of the excellent Notes from the Road and photographic contributor to the Birds of Abaco has a good tale of the pursuit of the apparent sighting of a Bahama Oriole on Abaco 2o years after its (supposed?) extirpation. You can read it HERE The Auk Read more about this journal and the birding history of the Bahamas HERE There is a Care2Action ‘Save the Bahama Oriole Before It Is Too Late’ petition HERE. It seems to have stalled somewhat, so it would be good to generate some more signatories. ** Mathematically inclined? Find out about the application of the stochastic process to the oriole’s situation. In a nutshell, this concerns the combined effect of several random adverse factors on sustainability, given that the oriole’s already very small population, very limited range and particular habitat requirements militate against breeding expansion, and therefore increase the likelihood of extinction. We can only hope this is not an inevitability…

There are 8 vireo species recorded for Abaco. The most common is the ubiquitous Thick-billed Vireo Vireo crassirostris – the only permanent resident vireo – whose cheery chirp is part of the background of bird song heard daily all over the island. The only other species you are likely to encounter without going out of your way is the summer resident BLACK-WHISKERED VIREO Vireo altiloquus, which breeds on Abaco. The other 6 are the White-eyed, Yellow-throated, Blue-headed, Warbling, Philadelphia, and Red-eyed Vireo. Of these, the first 2 are quite rare winter residents; and the other 4 are considered to be transients. 
The BWV’s song is similar to the Thick-billed Vireo, but (luckily) identifiably different. I’m not a great one for phonetic attempts at turning a bird call into a human sentence of the ‘Quick!-come-to-pick-up-a-brick’ and the ‘Skin-me-a-nice-bit-of-bonefish’ type. The Black-whiskered Vireo’s song has been described as sounding like ‘Whip, Tom Kelly’. But not to me. See what you make of it…
Brian Cox / Xeno-Canto
As with other vireo species, the BWV has a stout bill, a feature that helps to distinguish vireos from the many thin-billed warbler species on Abaco. The main signifiers are found on this bird’s head: the dark stripe right through the eye; the long white eyebrows; and the noticeable black lines – the ‘whiskers’ – on the sides of the neck. Other identification pointers are the pale underside with a yellow tinge to the flanks and undertail; and the red eyes (the red-eyed vireo, a very similar bird, lacks the whiskers).
Black-whiskered vireos feed mostly on insects in trees, bushes and undergrowth. They can sometimes be seen hovering while they forage. They also vary their diet with small quantities of berries. Here are two great shots of a mother BWV feeding a very large chick with a berry, followed by some vile insect.

The Bahamas produces frequent issues of wildlife stamps. Mostly birds, but also reef fish and sea creatures, animals, butterflies and flowers. I am gradually collecting an album of Bahamas wildlife stamps on a PHILATELY page. I’ve been having a look at a 16-bird issue from 1991 which reflects the wide diversity of species extremely well. Here is the set, with comparative photos of each bird. All but one were taken on Abaco, the rare Burrowing Owl being the exception. All the other 15 birds may be found on Abaco as permanent residents, either easily or with a bit of a look and some luck. I personally have not seen the Clapper Rail (though I saw a SORA) or the rarer Key West Quail-Dove.

The Mnemonic: that little aide memoire that helps you easily remember a fact. A suitable example hereabouts would be one for remembering the order of taxonomy: Kids Prefer Cheese Over Fried Green Spinach (Kingdom, Phylum, Class, Order, Family, Genus, Species). ‘ROY G BIV’ or ‘VIBGYOR’ were my childhood ones for the colours of the rainbow in order. Now I’d just look at a picture of a Painted Bunting. Who cares about the exact order? The colours are all there!
PAINTED BUNTINGS (Passerina ciris) belong to the Cardinal family (Cardinalidae) native to North America. Some would argue that the male Painted Bunting is one of the most beautiful birds. There are no ID problems with the male – once seen, never forgotten. However, these birds are inclined to skulk a bit, so despite their vivid colouring they aren’t always easy to see amid foliage. The plumage of female and juvenile Painted Buntings are green or greeny-yellow and may be even harder to see in coppice. The one below is an immature female.
These buntings are shy birds, but luckily their keenness for seeds outweighs their natural diffidence, and they enjoy feeders. They also eat small invertebrates such as spiders, snails, grasshoppers, and caterpillars, especially in the breeding season.
Male painted buntings are only too well aware how gorgeous they look (‘You’re so vain – I bet you think this post is about you…’). They may go in for ostentatious displays, including flying like a butterfly or all fluffed up or with quivering wings. Or all three. Sometimes this is to upstage another male; mostly it is to impress the laydeez.

Unsurprisingly the painted bunting was at one time very popular as a caged bird. Now though, it is illegal to catch or keep one. They are IUCN listed as Near Threatened and are protected by the U.S. Migratory Bird Act.
The photos above all come from the photographic archive amassed for “The Birds of Abaco” project. Credits to Tom Sheley, Tara Lavallee, Bruce Hallett, and Erik Gauger. Below is an omnium gatherum consisting of a gallery of rather good painted bunting photos from Wiki; a good video of PABUs singing; and for light relief a largely irrelevant yet quite charming 10 minute cartoon ‘The Rainbow Bird’ based on a South American folktale.
That is, essentially, because they are indeed Clappers. Rallus longirostris to be precise, or Clapper Rails. There are 4 rail species on Abaco, the Clapper being a permanent resident and not particularly uncommon. The others are the Virginia Rail and the Sora, both winter residents and less common (or in the Sora’s case, perhaps more furtive and less easy to find); and the Black Rail, which is generally agreed to be a ‘hypothetical’ for Abaco. That means they are believed to exist on Abaco but there are no confirmed sightings let alone any photos of one. However, last summer while we were taking a truck into the backcountry of South Abaco to locate hard-to-find birds for “The Birds of Abaco” book, the distinctive call of a Black Rail call was heard independently by two people on two different days in two different locations. I’ve heard another report since then. So they are out there somewhere, but keeping their heads down. The first to find one will have a considerable avian scoop!
Let’s start with some fabulous photographs by Tom Sheley. We used the first one in the book. By being patient, Tom managed to capture this bird having a quality preening session. Here are 4 shots from the sequence, including a rare one of the bird calling. To get the full glory of the detail, click on each image twice.
Clapper Rails are elusive birds of mangrove swamp and marsh, more frequently heard than seen. They tend to lurk around in foliage and are easy to overlook. You may come across one foraging secretively in the mud. Although they can both swim and fly, they prefer to keep both feet on the ground.When running, these rails look endearingly comical.
It almost goes without saying nowadays, but the biggest threat to these rather charming inoffensive birds is habitat loss. That is to say, mankind. Drive the bulldozers through the mangroves and marshland of sub-tropical coastal areas, chuck down a few acres of concrete… and the clappers will very soon become clapped out.
“TO RUN LIKE THE CLAPPERS”. This phrase seems to be fairly recent, probably dating from early in WW2. Some suggest it is a rhyming slam bowdlerisation of ‘run like hell’ with ‘clapper(s)’ standing for ‘bell’, along the lines of the Cockney “I bought a brand new whistle” (whistle and flute = suit). Almost all plausible explanations relate to bells, and some argue that it simply reflects the rapid speed of the clapper of a vigorously rung handbell.
STOP PRESS Uli Nowlan has sent her photo of a Clapper Rail, taken at the ponds north of Treasure Cay – a reminder that there is good birding to be done in that area of North Abaco – the bird action is not confined to South Abaco below MH…
