“THE DIET OF WORMS”: WORM-EATING WARBLERS ON ABACO

“THE DIET OF WORMS”: WORM-EATING WARBLERS ON ABACO

The little worm-eating warbler (Helmitheros vermivorum) is unique. Not because of its worm-eating propensities or its warbler-ishness (or the combination), but because it is the only species currently classified in the genus Helmitheros. The Swainson’s warbler was once in the same genus, but the WEWA saw off the competition.

SO WHAT IS A HELMITHEROS THEN, IF IT’S SO SPECIAL?

The word is Greek, meaning something like ‘grub-hunter’. And the Latin-derived vermivorum reflects the diet of a VERMIVORE – an eater of worms. But this description is, like a worm, somewhat elastic. It includes caterpillars, larvae, grubs, spiders and similar creatures. But whereas there are other warbler vermivores there is only one Helmitheros.

SOME WORM-EATING FACTS TO DIGEST

WEWAs are sexually monomorphic. Males & females are indistinguishable for most of the year
They can only be reliably sexed at the height of the breeding season…
…don’t ask. OK, a magnifying glass may be needed
They are believed to eat actual earthworms quite rarely. Moth larvae are their best treat
They are ground-nesting birds, one of only 5 new-world warblers to do this
Like some shore-birds, adults may feign injury to lure predators away from the nest
They are vulnerable to nest parasitism by brown-headed cowbirds & feral cats
Fires, deforestation, habitat change & diminished food resources are all threats to the species
As are pesticides, which destroy the primary food source and are in any case potentially toxic

DISTRIBUTION & CONSERVATION STATUS

The breeding range of the worm-eating warbler covers much of the eastern half of the US as far south as the Gulf Coast. It winters in the West Indies, Central America and southeastern Mexico. There is no overlap between summer and winter habitat. Because of the vulnerability of this ground-nesting species to a number of threats (see FACTS above), they are now IUCN listed as ‘Special Concern’ in New Jersey.

WHAT DO THEY SOUND LIKE?

In this case the song and call, as transposed into human, really does sound like the bird itself. The song is a rapid squeaky trill; and the calls for once do actually sound like ‘chip’ or ‘tseet’. See what you think (turn up the volume a bit).

THE (ORIGINAL) DIET OF WORMS – A DIGRESSION

Studied European history? Had a laugh over The Diet of Worms in 1521? This was an assembly (or ‘Diet’) of the Holy Roman Empire that took place in the City of Worms in Germany. There had already been several of them. This one resulted in an edict concerning Martin Luther and protestant reformation, with the consequence that… [sorry, I’ll spare you the details. I’ve started yawning already, just as I did at school I expect]

It is always instructive to look at Audubon’s fine depictions from the early c19. Here is his WEWA. Notice that it is here called Sylvia vermivora. So he had the worm-eating part, but the first part of the name – referencing woods – rather strangely relates to a group of old-world warblers. No, I’ve no idea why.

ABACO BALD EAGLE(S): AN EYRIE COINCIDENCE (GEDDIT?)

ABACO BALD EAGLE(S): AN EYRIE COINCIDENCE (GEDDIT?)

I absolutely knew this would happen. In a sense, I rather wanted it to happen. And now it has, and I have got my comeuppance. Bigly. Hugely. No sooner had I pressed ‘send‘ on my post 2 days ago bemoaning the absence of bald eagles in 2018 than corrections began to come in.

Harsh Judgemental Reader: “Do you mean you were wrong?”
- Contrite Writer: “Yes.”
HJR: “Did you check eBird before you fired off your intemperate post?”
- CW (in a small apologetic voice): “No.”
HJR: Well then, what have you got to say for yourself?”
- CW (*hangs head*): I’m very sorry, everyone. I’ll try to do better this time. Here goes:”

THE ABACO BALD EAGLE(S) OF 2018: IN NO WAY AWOL!

SIGHTING ONE

On October 25th legendary Bahamas birder Elwood Bracey and a party of 4 were looking out over the Marls from Sunset Ridge when they saw 4 birds flying high. Two were unmistakably turkey vultures; one was a magnificent frigatebird (ie totally non-eagle-ish); and the fourth was much larger, looking like a juvenile bald eagle. Any remaining doubts were dispelled when it dropped into a steep dive and smashed into the water, catching a fish in its talons, much like an osprey. There’s no room for confusion here: Woody has vast experience on Abaco and beyond – and besides, he had a powerful spotting scope and 4 birding witnesses. The ID is, as they say, solid. And it was posted on eBird. Which I should have checked. But didn’t. As Julia Roberts (qua Vivian Ward) actually did say, “Big Mistake. Huge!“

The problem here – you are ahead of me, aren’t you – is that a juvenile bald eagle does not resemble an adult. Rather than the familiar and symbolic look, they are dark brown with white flecks and mottling that changes as they grow older. A juvenile won’t even begin to look like a bald-headed adult until it is around 4 years old. Here are two comparisons of the confusing ages and stages.

SIGHTING 2

Within the last couple of weeks, a resident of Man-o-War Cay saw a huge brown bird – not an osprey, turkey vulture or red-tailed hawk – hunting chickens in the area. He told his family and identified the bird from looking at a photo of a juvenile bald eagle. I received this report – the first in time – from Charmaine Albury. Her brother was the sharp-eyed spotter. Had that been the only report, in the absence of a photo I might have had at least some doubt. Then Woody’s report arrived, a definite juvenile bald eagle only 3 weeks before, over the Marls. From there, with its spectacular eyesight it could practically have seen the individual chickens on Man-o-War. So it’s a good fit for ID.

WHAT’S THE CONCLUSION?

I’d say that right now on Abaco we have a single juvenile bald eagle. It’s a vagrant, away from its usual hunting ground but unchallenged in the skies where it has ended up. There has been the usual autumn extreme weather (though Abaco has dodged the worst of it) to throw a young bird of course in the last couple of months. So, rather late in the day, we really do have an Abaco Bald Eagle for 2018.

BLACKPOLL WARBLERS ON ABACO: UNCOMMON TRANSIENTS

January 16, 2017 by Rolling Harbour

BLACKPOLL WARBLERS ON ABACO: UNCOMMON TRANSIENTS

The Blackpoll Warbler Setophaga striata is a “TR3” on Abaco. Which is to say, the species is classified as an uncommon transient in its migration, and as such it is rarely seen on Abaco. Apart from anything else the window of opportunity of seeing one in the Fall or in Spring is limited by the length of time they pause on Abaco to catch their breath. Also, they are small birds that do not draw attention to themselves. They hang around in the coppice foliage rather than parading out in the open; and their call is a tiny ‘tsip‘ sound (as with so many other small birds…).

Fortunately, on Abaco’s warbler magnet Man-o-War Cay, alert birder Charmaine Albury was out and about with her camera to record a sighting. I should say that during the writing of THE BIRDS OF ABACO, I never managed to obtain a single image – however poor – of a Blackpoll Warbler actually taken on Abaco (a qualification for inclusion) from any of the many sources I used. So sadly, this pretty warbler does not feature in the book.

The summer breeding area for blackpolls covers northern North America from Alaska through most of Canada, the Great Lakes region and New England. In the fall, they fly South to the Greater Antilles and the northeastern coasts of South America. The summer and winter areas are very distinct, as the distribution map shows:

Despite their diminutive size**, blackpoll warblers generally undertake their long-distance migration – often over open water – non-stop or with a single stopover. Their migration has been the subject of many scientific studies. One of the longest distance non-stop overwater flights ever recorded for a migratory songbird was made by a BLWA. Which all goes to explain why the species is so rarely seen along the migration route: unlike many migrating birds, they make few, if any, stops along the way.

Of the many stats I have read through, I chose one to demonstrate the stamina of these little birds. In one study, an number were fitted with tiny geolocators. These revealed an average migration journey of around 1600 miles, with the non-stop trip being completed in 3 days by at least one bird.

“Transoceanic migration by a 12 g songbird”

The maps above show blackpoll warbler migrations recorded for 5 birds in a study that indicates that, while a direct overwater route is preferred in the fall migration, the return journey in spring is more leisurely, and overland (it looks as though only 3 birds made it home).

The study quoted is by William V. DeLuca, Bradley K. Woodworth, Christopher C. Rimmer, Peter P. Marra, Philip D. Taylor, Kent P. McFarland, Stuart A. Mackenzie, D. Ryan Norris (Published 1 April 2015. DOI: 10.1098/rsbl.2014.1045)

** I came across the statement that “The blackpoll warbler… attains the weight of a ball point pen”. I find this an unhelpful comparison. I know what is meant, but I find it hard to think of a ball of feathers in terms of a writing instrument. Maybe it’s just me? [Astute Reader: I’m afraid so…]

YOU MENTIONED THAT THEY GO ‘TSIP’. WHAT DOES THAT EVEN SOUND LIKE?

RACCOONS ON ABACO: A MIXED BLESSING?

December 16, 2016 by Rolling Harbour

RACCOONS ON ABACO: A MIXED BLESSING?

Abaco, like the rest of the Bahama Islands, is strangely short of native land mammals. The last of the wild ABACO BARBS – descendants of Spanish Colonial horses of high pedigree – died very recently. The proud Barbs are no more. But they, of course, were an introduced species. There are the hard-breeding, hard-hunted hogs. And feral potcakes, unowned or disowned. Many feral cats. Maybe a few rabbit escapees. And bats: several of the dozen (or so) Bahamas species are found on Abaco. At one time there was the shy nocturnal HUTIA that had the distinction of being – or having been – endemic to many of the islands. Not on Abaco, sadly – its own subspecies the Great Abaco Hutia had become extinct by the c17. You’ll have to go to the Exumas to see a hutia.

HEY! THERE ARE RACCOONS, AREN’T THERE?

This endearing-looking creature was photographed on Abaco by Charmaine Albury

Raccoons are a non-native species, probably introduced in the Bahamas many decades – perhaps a couple of centuries – ago. They are thought to have been brought to New Providence originally. More recently they arrived on Abaco – possibly as pets in the first place, which were then released or escaped. And they are spreading: as recently as April 2012 an excellent article in the Bahamas edition of COASTAL ANGLER MAGAZINE introduced “Eleuthera’s Newest Mammal”.

RACOON PROS

Cuddly, furry, cute-looking, quite high on the well-known scientifically-based ‘ADORBS’ scale (Animals Deemed Outrageously, Ridiculously, Breathtakingly Strokeable)
Comfortingly familiar despite being wild animals (NB potentially aggressive)
Don’t have the same drawbacks as skunks
Have valuable fur
Pelts can be used for Davy Crockett hats

RAC-CONS

Considered to be “one of the world’s most omnivorous animals”
Known to wreak havoc with certain crops, eg watermelons
Canny and adept hunters, including at night; good climbers to treetop level
Suspected of predation of land crabs (depriving ‘natural’ predators of the pleasure)
Compete with birds for fruit, berries and nectar
Relish birds’ eggs. Low and ground-nesting birds are particularly at risk throughout season
On Abaco, a major conservation program has been needed to protect the nests of the Abaco parrots in the limestone caverns of the national park from raccoons, feral cats and rodents
Eat small birds, curly tail lizards, anoles and suchlike
Can be aggressive to humans – note the handy claws clearly shown in the photo above

LIVE AND LET LIVE?

“The authors of the study Taxonomic status and conservation relevance of the raccoons of the West Indies (2003) hold that the Bahamian raccoon is an invasive species which itself poses a threat to the insular ecosystem.The Government of the Bahamas has this species listed as up for eradication on the islands of New Providence and Grand Bahama”.

So the official line favours eradication of a potentially harmful non-native species – failing which, presumably containment of numbers. Trapping is one way to achieve this – and there are both humane as well as cruel ways to do so. However, trapping in one place, only to release somewhere else is clearly not an option. But it would provide the opportunity to neuter / spay the animals and slow or prevent the reproductive spread of the creatures. Hunting raccoons is another method. It’s not currently a significant sport, but neither are raccoons protected. Their fur has a value, and some say they could provide a source of somewhat gamey meat.

Or they could be just left as they are, as attractive creatures now well-established, despite the inevitable risks to native species such as the reviving population of Abaco parrots, now at sustainable numbers. On Abaco, reduced to its basics the $64k question might be: which would you prefer in the future? More raccoons or fewer parrots (or indeed, no parrots at all)?

PUMPKIN

I wouldn’t wish to run the risk of influencing the delicately balanced arguments about the raccoons of the Bahamas, but will you just take a look at this? The perfect fit for the acronymic descriptor A.D.O.R.B.S!

Coastal Angler magazine, BNT / Erika Gates, Bahamas Weekly, Charmaine & Becky for the Abaco photos, plus Wiki / open source, Buzzfeed / YouTube & don’t get stuck into the rest of the cutesy viddys… Stop Press: added above the pros & cons – a great recent photo by Cheryl Wile Ferguson (nb not taken on Abaco)

At least as far as stamps are concerned, the raccoon gets equal billing with the hutia (and the bat)

SCOOP! BLACK SKIMMERS FOUND ON ABACO

SCOOP! BLACK SKIMMERS FOUND ON ABACO

I have been waiting soooooo long for photos of black skimmers (Rynchops niger) taken on Abaco. When we were putting together “The Birds of Abaco”, I had just one skimmer image – a bird standing self-consciously on a jetty facing the camera, a shot into difficult light with a low-res unusable picture resulting. I never collected another qualifer (‘Abaco birds only, natural surroundings, no feed trails’). So sadly they don’t feature in the book.

Black Skimmer, Abaco Bahamas (Charmaine Albury)

These rather special seabirds breed in North America. Very sensibly (and like many humans), they migrate south to overwinter in warmer climes, including the Caribbean. But in the northern Bahamas sightings are very rare. Or maybe I should say, reports of them are rare, and photos the more so. They are classified as WR4, very uncommon winter residents.

Black Skimmers, Abaco, Bahamas (Charmaine Albury)

But now the Rolling Harbour duck is broken (so to speak). Two skimmers were spotted yesterday by Man-o-War Cay resident Charmaine Albury, a keen birder and photographer. Her images of this chance sighting as the pair flew gracefully past to land on the beach show enviably quick reactions with the camera! We have a Big Scoop here. Two of them.

WHAT’S SO SPECIAL ABOUT THEM?

EYES These birds have dark brown eyes. So far, so what. But their pupils are unique in birdland: they aren’t round, but vertical – like a cat. As far as I can make out, this is to maximise the fish-catching potential of their other speciality feature…
BILL Take a look at this close-up of a great photo by Don Faulkner. Check out that unmistakeable bill, with the extraordinary elongated lower mandible.

HOW DOES THAT HELP?

When hunting for food, skimmers fly fast and very close to the surface of the sea. The long thin lower mandible cuts through the water … and when it comes into contact with its prey, the bird snaps shut the upper mandible onto it.

OK, SHOW ME!

NOT ENOUGH. I WANT TO ACTUALLY WATCH THEM DO IT…

This short video by EstuaryLiveTV shows skimmers feeding in real time, then in slow motion in an estuary. They are looking for fish, crusteaceans and molluscs. It explains all.

MELLOW YELLOW: HOODED WARBLERS ON ABACO

September 29, 2016 by Rolling Harbour

MELLOW YELLOW: HOODED WARBLERS ON ABACO

The Hooded Warbler (Setophaga citrina) breeds in eastern North America in summer, and winters in Central America and the West Indies. On Abaco they are classed as WR3, ‘uncommon winter residents’. The range map below reveals one strange aspect of their habitat. It looks as though they choose not to live in Florida either in summer or winter. I’m sure they must be found there as transients; and there must presumably be some small breeding or wintering populations in Florida. Or both. But it’s hard to understand why Florida does not seem to suit them.

220px-wilsonia_citrina_map-svg

ABACO WARBLER HOTSPOT

On Abaco, I have only ever had reports of Hooded Warblers from Man-o-War Cay, which seems to be a warbler hotspot every season. There are 37 WARBLER SPECIES recorded for Abaco. FIVE WARBLER SPECIES are year-round residents. Of the migratory 32, at least two dozen seem to favour Man-o-War for their winter break in the sun. MoW resident Charmaine Albury, who took the main photos in this post, has already counted 14 different warbler species before the end of September. She has found up to 5 species in a tree at the same time.

WHAT’S IN A NAME?

There are periodic upheavals in Birdland which, following research, lead to an official reclassification of a particular bird species or genus. In 2011, many warblers that were cheerfully going about their business under the classification Dendroica found themselves merged into the older ‘priority’ genus Setophaga (Greek for ‘moth eating’). The Hooded Warbler, formerly Wilsonia, has found itself similarly merged into Setophaga – a kick in the teeth for the naturalist ALEXANDER WILSON, for whom the bird was named (along with many others – his plover being a well-known example on Abaco).

hooded-warbler-copy

WHY ‘CITRINA”? (FUN FACT!)

The word relates to lemons – citrus fruits – and their colour, and is undoubtedly apt for the hooded warbler. However the semi-precious calcite gem, ‘Citrine’ (same word origin) is not lemon coloured but (disappointingly) brownish.

imgres natural-citrine-calcite

This little warbler has a plain olive / greeny-brown back, and a bright yellow face and underparts. There are white feathers on the outsides of their under-tail (I’m sure there’s a more technical word for this…) – see header image. Only males have the black hoods and bibs; females have an olive-green cap.

Hoodies forage for insects in low vegetation and dense undergrowth, or catch them by HAWKING from a branch or twig. Sadly, they are one of the species that are targeted by brown-headed cowbirds, the cruel exponents of brood parasitism. These birds are rarely found transients on Abaco at present, but they are a robust species and there is evidence that their range is increasing. In some areas there are controlled (euphemism for… er… dispensed with). I’d favour that approach for Abaco, should they show signs of inflicting their evil ways on the resident breeding population of small birds.

Audubon plate-110-hooded-warbler-final

Hooded Warbler in Audubon’s Birds of America

WHAT DO THEY SOUND LIKE?

I am often at sea with the attempts to turn birdsong into to memorable words of phrases. Yes, a Bobwhite sounds a bit like a quizzical ‘Bob… White?‘. But I rarely ‘get’ the “I’d-like-a-Kalik-with-my-Conch” and suchlike. For what it is worth, I learn that for the Hooded Warbler “the song is a series of musical notes which sound like: wheeta wheeta whee-tee-oh, for which a common mnemonic is “The red, the red T-shirt” or “Come to the woods or you won’t see me“. See what I mean? Anyway, we can all agree that “the call of these birds is a loud chip.” As with so many species!

So here’s what to listen out for (recording: FLMNH). Suggestions for a suitable phrase welcome!

1291c 3646

If you come across a bird that looks like a hooded warbler, but is motionless and makes no sound unless you squeeze it, you may have found the subspecies Audubonus stuffii, which is found mainly in the Amazon and E. Bay regions. 51idfxzal

OPTIONAL MUSICAL DIVERSION

I haven’t had time to musically divert for a while. My title refers, of course, to the ‘psychedelic pop’ song by Donovan, released in the US in 1966 and the UK in early 1967. The theory is that the song relates to the supposed (but mythical) hallucinogenic high to be had from smoking dried banana skins. There are an explicit interpretation for the ‘electical banana’ which we need not go into in a family blog. There was a rumour, now discredited, that Paul McCartney supplied the “quite rightly” in the chorus. Anyway, to chime in with the mood of the time, one of the first ‘coffee shops’ in Amsterdam was called Mellow Yellow.

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!

Bananaquit, Abaco (Char Albury)

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

Bananaquit juvenile, Abaco (Char Albury)

As the juveniles grow, their colouring becomes stronger until eventually they are hardly distinguishable from their parents Bananaquit juvenile, Abaco (Char Albury) Bananaquit, Abaco (Char Albury)

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!

BUTTERFLIES ON ABACO (7): LONG-TAILED SKIPPER

The Abaco Neem Farm is run by Nick Miaoulis with a passion and commitment to the environment matched by few. The farm products can be found in the excellent Abaco Neem shop in Marsh Harbour. This is wonderful place for birding. Besides fruit trees of many kinds, there is a perfect mix of coppice and pine-forest to satisfy the most habitat-pedantic species.

Long-tailed Skipper Butterfly, Abaco (Keith Salvesen) 3

Around the fruit trees, wildflowers are encouraged to thrive. These attract bees (Nick also has hives) and of course butterflies – not forgetting moths. Amongst the fluttery creatures, we found a long-tailed skipper (Urbanus proteus), a butterfly found in tropical and subtropical areas. It is a striking creature, with iridescent blues on the body and two long tails extending from the hindwings. The caterpillar is said to be a crop and ornamental plant pest; the butterfly is described as uncommon (maybe for the Bahamas, anyway).

THE BAHAMA WOODSTAR NEST: A CHRISTMAS STORY FOR A NEW YEAR

THE BAHAMA WOODSTAR NEST: A CHRISTMAS STORY FOR THE NEW YEAR

And it came to pass that on the first day of December in the Year of Our Lord 2015, the time came upon a mother hummingbird; and she laid her tiny egg in a small nest in the place that is called Man-o-war, which is to say ‘The Island of Pretty Birds”. And on the next day, she laid a second tiny egg in that nest also. For this was in the time of the first Woodstar nesting of the season.

And the days passed, even as the mother hummingbird sat upon the nest whereat she had laid her eggs. And verily was she patient, for it was known to her that the eggs would not hatch until certain days were past

Bahama Woodstar nest with eggs, Abaco (Charmaine Albury)

Yet still the eggs hatched not, though their colour became paler… Bahama Woodstar nest with eggs, Abaco (Charmaine Albury)

But on the 19th day hatched the first egg; and likewise the second egg upon the 21st day. And two (mostly) naked hatchlings were made visible. Bahama Woodstar nest with hatchlings, Abaco (Charmaine Albury)

On the 25th day, which is to say the day of Christ’s Mass, the hatchlings had grown; and their raiment of feathers was coming upon them to clothe their nakedness Bahama Woodstar nest with hatchlings, Abaco (Charmaine Albury)

And as they grew the chicks (for thus were they named) were snug and safe in their small nest, even as their mother and their father, who did build it together and furnish it with soft materials, had ordained

1170953_10207164189916859_1353675663828625458_n

By the 31st and final day of the old year, which is to say the day before Earth’s renewal in another year, the chicks had greatly grown; and feathers were about their persons. And their appearance was of small birds which would soon fly from that place and live happily in a New Year at Man-o-war Bahama Woodstar nest with chicks, Abaco (Charmaine Albury)-1

Thanks for all fabulous photos to Charmaine Albury, who is lucky enough to be a Woodstar magnet on Man-o-War Cay. With her family, she watches these events unfold every year at her house, and manages to record them without ever disturbing these wonderful little birds

WEST INDIAN WOODPECKERS ON ABACO: GUEST POST

April 3, 2015 by Rolling Harbour

WEST INDIAN WOODPECKERS ON ABACO: GUEST POST

The WEST INDIAN WOODPECKER Melanerpes superciliaris is a specialist bird of Abaco, where it is common. The only other island in the Bahamas where it is found is San Salvador, where it is uncommon. Formerly found on Grand Bahama, it is now believed to be extirpated from that island, with no recent recorded sightings. In the early days at Delphi, we had to put up 2 nest boxes under the eaves to discourage the woodpeckers from destroying the woodwork – very effective, since they are now used every year by a pair that raises a family in one of the boxes and, even before the chicks have fledged, are busy kitting out the second box for a second family…

Charmaine Albury is a resident of Man-o-War Cay, Abaco. A photographic contributor to THE BIRDS OF ABACO, she is an enthusiastic birder and very handy with a camera. MOW has had a great winter season for birds, especially warbler species, and Charmaine has been recording her sightings and posting about them regularly. She has now started a photographic Facebook page SEES THE DAY which I commend to anyone wanting an overview of the rich birdlife of Abaco. This post shows some of her excellent recent photographs of West Indian Woodpeckers on Abaco. The male has the striking red crown; the female has a smaller, paler cap.

February 2, 2015 by Rolling Harbour

In 2012 I wrote a post about the comparative rarity of the American Robin on Abaco, which had surprised me. They overwinter in Florida, and they might conceivably range further more often than they do. It turned out that one or two may be reported one year, none the next. I listed a number of sightings and some comments by Woody Bracey, but I lacked any photos of these birds taken on Abaco. I had to make do with wiki and bad ones taken in the US by me (including stuffed ones in the Natural History Museum, NYC – an act of desperation!). You can see the post HERE

Nina Henry, a photographic contributor to BIRDS OF ABACO, had some good fortune last March 2014 when she found these 3 birds during her trip to Abaco. Maybe March is a good time for them – perhaps a few call in as they start to make their way north for the summer.

Many past sightings have been on the Cays rather than the main island. Here’s a recent photograph taken by Charmaine Albury on Man-o-Way Cay

Meanwhile I have been able to improve slightly on the tiny distant AMRO I posted before, with one taken more recently – still not on Abaco but in NYC. Closer, but definitely no cigar yet…

VIREOS ON ABACO (1): GOING CHEEP – THE BLACK-WHISKERED VIREO

August 26, 2014 by Rolling Harbour

GOING CHEEP ON ABACO: THE BLACK-WHISKERED VIREO

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…

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.

Q: WHAT IS CUTER THAN A BAHAMA WOODSTAR HUMMINGBIRD ON ABACO?

Q: WHAT IS CUTER THAN A BAHAMA WOODSTAR HUMMINGBIRD ON ABACO?

A: A BABY BAHAMA WOODSTAR HUMMINGBIRD ON ABACO

Charmaine Albury from Man-o-War Cay, Abaco, has taken some fabulous photographs of a nesting Bahama Woodstar Hummingbird at her home. With her kind permission, I am delighted to display a selection of them below. The adult is a female, and lacks the striking purple gorget of the male. The baby’s plumage is… spiky! The cup nest is beautifully constructed, made from plant down, bark and cobwebs, balanced in a string of lights. The size of the bulbs give a very clear idea how tiny these sweet little birds are. These are photos to be viewed in wonderment and awwwwwwwwww….

This hummingbird species nests all year round. The female lays 2 elliptical white eggs, which she incubates for 15–18 days. Not only is the baby in these pictures in a very small nest, it is sharing it with an unhatched and presumably sterile egg. Then again, two babies would be even more of a squash… 541844_10201470918508632_1470337409_n

The Bahama Woodstar Calliphlox evelynae is endemic to the Bahamas, found only on there and as an occasional vagrant in south east Florida. On Abaco, it is one of four endemic species found on the island – the others are the Bahama Swallow, the Bahama Warbler and the Bahama Yellowthroat. Together with the unique ground-nesting ABACO PARROT, these are among the most special birds of Abaco.
