WHITE-TAILED TROPICBIRDS: EFFORTLESS ELEGANCE

WHITE-TAILED TROPICBIRDS: EFFORTLESS ELEGANCE

I am interrupting my intended sequence of posts (I try to plan ahead a bit…) to bring you some gorgeous white-tailed tropicbirds (Phaethon lepturus catesbyi) seen within the last week near the Low Place on Man-o-War Cay. There were 6 in the group, flying high, flying low, circling, dipping down, flirting  – all of this taking place just offshore.

Sally Chisholm, Abaco birder and photographer, was with Todd Pover of CWFNJ, engaged in the final piping plover count of the season before the birds return to their summer breeding grounds [check out ABACO PIPING PLOVER WATCH if you are interested]. Sally and Todd were distracted from the matter in hand as the group of tropicbirds glided and swooped through the air. It was a free demonstration of beautiful flying skills that can be matched by few other species.

It became obvious that courtship was involved. As Sally vividly describes it, “The birds were observed for more than 15 minutes making wide circles, at times flying out of sight across towards Great Abaco and coming back flying low over the same area on MOW. Two birds would interact with a lot of “keck-keck-keck”, and then one of the pair flew down to land several times in the same crevice of the iron shore. It first appeared that the bird was landing for food but none of the photos showed anything carried. The display looked to be one of courtship and was amazing to watch”.

TROPICAL TOPICS

  • WTTR plunge-dive for fish and squid, sometimes submerging completely
  • Or they swoop and skim their prey from the surface
  • Another technique to take flying fish in the air (I’d love to see that…)
  • WTTR have no fixed breeding season, and may nest year-round
  • Nesting is colonial or in pairs in a particular area, or even in isolation
  • Pre-mating behaviour involves courtship displays (as here)
  • A pair will fly together, one above the other then…
  • …the higher bird bends its tail down to touch tail of lower bird and [veil drawn]
  • They nest in crevices, holes in rock, on ledges, on the ground under vegetation
  • Chicks are fed by both parents using regurgitation
  • The same site may be re-used for several years by the same pair

CUBAN PEWEE: ‘NATURE’S LEAST SCARY TYRANT’

CUBAN PEWEE: ‘NATURE’S LEAST SCARY TYRANT’

The small bird featured here is a CUBAN PEWEE Contopus caribaeus bahamensis (sometimes called the Crescent-eyed Pewee – see image for why this is so). It is without a doubt a tyrant. At barely 6″ long, it is the smallest tyrant you are likely to encounter in the Bahamas or indeed anywhere else. However it does happen to be a member of the family Tyranidae. These are the flycatchers, and on Abaco they include the larger LA SAGRA’S FLYCATCHERthe still larger LOGGERHEAD KINGBIRD and (a summer visitor only) the GRAY KINGBIRD (this last link explains the difference between the two kingbirds).

Cuban Pewee, Contopus caribaeus bahamensis, Casuarina Abaco Bahamas (Keith Salvesen Photography)

The Cuban Pewee is permanently resident on Abaco, and can be found in both pine woods and coppice. When returning to its perch after a fly-catching sortie – ‘hawking’ on the wing – this wee bird gives a characteristic flick of the tail. The bird featured here was in the rough scrub behind the beach of the beautiful bay at Casuarina. It became a favourite of mine simply by being completely unafraid of me, and accepting my extremely slow approach (3 inches at a time) with apparent interest mixed in with an endearing willingness to pose, even when I could almost have reached out and touched it.

Cuban Pewee, Contopus caribaeus bahamensis, Casuarina Abaco Bahamas (Keith Salvesen Photography)

Unlike many creatures, it did not seem concerned by eye-contact. It responded when I made a faint clicking sound by rather sweetly putting its head on one side. However, as I got as close to it as I dared, it began to fidget slightly (possibly feeling camera-shy). So I shuffled slowly back, so as not to disturb it in its own territory, where it was the resident and I was the intruder.

Cuban Pewee, Contopus caribaeus bahamensis, Casuarina Abaco Bahamas (Keith Salvesen Photography)

These close-ups clearly show the tiny hooked tip at the end of the upper beak, which (as in other tyrant species) relates to the business of catching flies. Also like other flycatchers, the Cuban Pewee has very distinctive whiskers around the base of the beak. In fact, these are not whiskers as such – not hairs so much as feathers that have modified into bristles. These act as ‘tactile sensors’ to assist the detection and targeting of aerial insects as the bird darts from a perch to intercept some passing tasty winged morsel. 

Cuban Pewee, Contopus caribaeus bahamensis, Casuarina Abaco Bahamas (Keith Salvesen Photography)

The range of the Cuban Pewee is limited almost entirely to Cuba and the Bahamas, so it is very region specific. And how lucky we are to have these cute little specimens on Abaco. I note that the Audubon site calls them drab, which I think is a little unfair. Merely because a bird is not decked out like a PAINTED BUNTING or startlingly marked like a male RED-WINGED BLACKBIRD does not make it drab. I prefer the word ‘subtle’.  I like GRASSQUITS too, for the same reason: too often maligned as ‘dull’.

Cuban Pewee, Contopus caribaeus bahamensis, Casuarina Abaco Bahamas (Keith Salvesen Photography)

It is sometimes tempting to anthropomorphise such close encounters in terms of imputed human / creature empathy. It is probably best to try to resist that attitude (‘inter-species condescension’, as you might term it). But as I withdrew, leaving this little bird undisturbed on its branch, I did experience a strange feeling of mutual understanding and… [I must interrupt myself here. I’m a lawyer, so that’s quite enough of that sort of emotive nonsense]

KIRTLAND’S WARBLERS: DESERVING PHILATLEY…


Kirtland's Warbler, Abaco, Bahamas (Woody Bracey)

KIRTLAND’S WARBLERS: DESERVING PHILATLEY…

As I have mentioned before, the BAHAMAS POSTAL SERVICE has an exceptionally good record for producing wonderful, colourful stamps showcasing the abundant wealth of natural history in the archipelago. Birds, reef fish, turtles, marine mammals, butterflies, plants and flowers – all these and more have featured on the stamps of the Bahamas for many years. There’s quite a collection of them on a display page of their own HERE.

Quite by chance I recently came across a significant philatelic tribute to one of the rarest Bahamas winter visitors, the Kirtland’s Warbler (Setophaga kirtlandii): a complete commemorative sheet of stamps. Reader I bought it (= ‘won’ it on eBay – $2.75!). Produced in conjunction with the WWF, it is a model of conservationist sensitivity.

The sheet of 16 stamps depicts 4 x 4 KIWA variations: a female at the nest; a singing male; a female feeding young; and a juvenile feeding in the Jack pines of its summer habitat, prior to its long Fall migration to Abaco and the Bahamas.

I am not a stamp collector, but I do appreciate it when countries take the trouble to showcase their flora and fauna among the notable people, sporting heroes, modes of transport and Harry Potter characters. As I say, the Bahamas is very good in this respect.

KIRTLAND’S WARBLERS: ALL YOU NEED TO KNOW

KIWA ON GREEN TURTLE CAY: A FIRST FOR ABACO

In the breeding grounds in very limited areas of Michigan and Ohio, the KIWAs are carefully monitored. Vince Cavalieri is a bird expert in those parts, and his bird below was photographed in the heartland of their preferred summer habitat. Vince wrote the following caption:

In 1987 the Kirtland’s Warbler was a hair’s breadth from extinction. A century of fire suppression and encroachment into their habitat by the brown-headed cowbird had reduced its already small population to a tiny number of birds in just a few Michigan counties. A prescribed fire that got out of control may have saved them, creating enough habitat that it gave conservationists enough time to figure out how to save them (highly prescriptive habitat creation and cowbird control). Today their comeback has been so successful that they have been proposed for removal from the endangered species list. They still remain the stuff of birding legend. A tiny range mostly restricted to north central Michigan, a big beautiful warbler with a loud and cheerful song, easy to see and confiding once found. A bird worthy of long travel to check off your list.

‘CARRION SCAVENGING’: TURKEY VULTURES ON ABACO


‘CARRION SCAVENGING’: TURKEY VULTURES ON ABACO

turkey-vulture

Turkey Vultures Cathartes aura [TUVUs, to use their Alpha Bird Code for brevity] are a familiar sight flying over Abaco, wheeling effortlessly overhead on thermals or gliding with the wind in singles, pairs, or flocks. Statistically, 83% of all photographs of turkey vultures are taken from below and look like this: 

Turkey Vulture, Abaco Bahamas (Bruce Hallett)

A very good cameraman with a very good camera and very good luck might catch this

Turkey Vulture, Abaco Bahamas (Nina Henry)

Of in-flight shots, 57% are taken in unhelpful light or conditions, and look like the image below (mea maxima culpa). On a positive note, this picture shows the extreme delicacy of the wing-tip feathering (starboard wing, anyway) that enables these birds to adjust their direction and speed with minimal effort.Turkey Vulture Abaco Bahamas (Keith Salvesen)

TUVUs have a wide range in the Americas and the Caribbean, and will prosper in almost any type of habitat. This is mainly because these large birds are almost exclusively carrion feeders, and carrion is everywhere. They spend their days scavenging, or thinking about scavenging, or recalling successful locations to re-scavenge. They do not generally kill live creatures.turkey-vulture

The word ‘vulture’ derives from the latin word ‘vulturus‘ meaning ‘ripper’, ‘shredder’, or in more recent times, ‘very loud Metallica song*‘. TUVUs have very good eyesight, and an acute sense of smell that enables them to detect from a considerable distance the scent of decay and consequent release of the chemical ethyl mercaptan. The smell is variously described as ‘persistent penetrating decayed cabbage’ or a ‘pungent malodorous skunk-like odour’. A breeding pair will raise two chicks, which revoltingly are fed by the regurgitation of all the rank and foul… excuse me a moment while I… I feel a little bit… ~~~~~~~~~~~ …alright, fine again now.

Turkey Vulture Abaco Bahamas (Craig Nash)

When they are not flying, feeding, breeding or nourishing their young, TUVUs like best to perch on a vantage point – a utility post is ideal. But unusually for a bird, you won’t ever hear them sing or call. They lack a SYRINX (the avian equivalent of a larynx), and their vocalisation is confined to grunting or hissing sounds. Here’s a single hiss (at 10 / 15 secs).

turkey-vultureThese vultures are often seen in a spread-winged stance, which has several functions that include drying the wings, warming the body, and baking bacteria. Possibly it also reduces the miasma of rotting meat that may surround them after a good meal.

Turkey Vulture Abaco Bahamas (Keith Salvesen)

Equally happy to spread their wings on a debris-strewn shoreline

Turkey Vulture Abaco Bahamas (Keith Salvesen)10 SCAVENGED TURKEY VULTURE FACTS FOR YOU TO PICK OVER

  • One local name for a TUVU is ‘John Crow’
  • An adult  has a wingspan of  up to 6 feet
  • Sexes are identical in appearance, although the female is slightly larger
  • The eye has a single row of eyelashes on the upper lid and two on the lower lid
  • TUVUs live about 20 years. One named Nero had a confirmed age of 37 
  • LEUCISTIC (pale, often mistakenly called “albino”) variants are sometimes seen

Leucistic (white) Turkey Vulture, Florida Keys (amy-at-poweredbybirds)

  • The TUVU is gregarious and roosts in large community groups
  • The TUVU has few natural predators
  • Though elegant in flight, they are ungainly on the ground and in take-off
  • The nostrils are not divided by a septum, but are perforated – from the side one can see through the beak [some humans also suffer from this condition. They tend to ‘sniff’ a lot]

Turkey Vulture Abaco Bahamas (Craig Nash)Turkey Vulture headshot Wiki

REVOLTING CORNER / DEPT OF ‘WAY TOO MUCH INFORMATION’ 

SQUEAMISH? THEN LOOK AWAY NOW

UNATTRACTIVE HABITS The Turkey Vulture “often defecates on its own legs, using the evaporation of the water in the feces and/or urine to cool itself, a process known as UROHIDROSIS. This cools the blood vessels in the unfeathered tarsi and feet, and causes white uric acid to streak the legs”. The droppings produced by Turkey Vultures can harm or kill trees and other vegetation. Maybe don’t park your nice car under one of their perching posts…

 

HORRIBLE DEFENCES The main form of defence is “regurgitating semi-digested meat, a foul-smelling substance which deters most creatures intent on raiding a vulture nest. It will also sting if the predator is close enough to get the vomit in its face or eyes. In some cases, the vulture must rid its crop of a heavy, undigested meal in order to take flight to flee from a potential predator”

Turkey Vulture in flight, Abaco Bahamas (Charlie Skinner)

DIETARY NOTES TUVUs tend to prefer recently dead creatures, avoiding carcasses that have reached the point of putrefaction. They will occasionally resort to vegetable matter – plants and fruit (you could view this as their side-salad). They rarely, if ever, kill prey – vehicles do this for them, and you’ll often see them on roadsides feeding on roadkill. They also hang around water, feeding on dead fish or fish stranded in shallow water. 

ECO-USES If you did not have birds like this, your world would be a great deal smellier and less pleasant place, with higher chance of diseases from polluted water and bacterial spread. TUVUs kept the highways clear and work their way round the town dumps recycling noisome items. 

turkey-vulture

FORAGING TUVUs forage by smell, which is uncommon in birds. They fly low to the ground to pick up the scent of ethyl mercaptan, a gas produced by the beginnings of decay in dead animals. Their olfactory lobe in the brain is particularly large compared to that of other animals.

SEX TIPS Courtship rituals of the Turkey Vulture involve several individuals gathering in a circle, where they perform hopping movements around the perimeter of the circle with wings partially spread. In humans, similar occasions are called ‘Dances’. A pair will fly, with the female closely following the male while they flap & dive… then they land somewhere private and we draw the veil…

PAINTED BUNTINGPainted Bunting, Abaco (Erik Gauger)

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

Painted Bunting, Abaco (Tara Lavallee)

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

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

STAR ANIS ON ABACO


Smooth-billed Anis, Bahamas (Paul Harding)

STAR ANIS ON ABACO

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

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

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


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

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

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

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

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

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

Kirtland's Warble, Sandy Point Abaco Bahamas (Roger Neilson)

AN EXCITING SIGHTING

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

KIWA CHIP CALL Paul Driver / Xeno Canto

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

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

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

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

WHAT ARE THE MAIN THREATS TO THE SPECIES?

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

ROYAL TERNS ON THE LONG DOCK, CHEROKEE


Royal Tern, Long Dock Cherokee Abaco Bahamas (Keith Salvesen)

ROYAL TERNS ON THE LONG DOCK, CHEROKEE

Royal terns Thalasseus maximus seem to have a great liking – quite rightly – for the charms of Cherokee, Abaco. Of the 12 tern species recorded for Abaco, ROTEs are the only permanent residents. Most of the others are summer visitors; a couple are winter visitors; and the rest pass through as migrating ‘transients’, stopping to rest and refuel on their long journeys. So ROTEs are undoubtedly the most commonly found terns on Abaco, and some might say the finest. And Cherokee Long Dock is one place to find them.

Royal Tern, Long Dock Cherokee Abaco Bahamas (Keith Salvesen)

The historic LONG DOCK at Cherokee stretches far out into the sea to accommodate the varying tide levels of the area – click the link for more information and photos. It is a memorable feature for visitors, and much loved by locals. Also by the royal terns. 

Royal Tern, Long Dock Cherokee Abaco Bahamas (Keith Salvesen)

The dock provides an ideal safe platform for ROTEs to congregate and hang out. They have a perfect view of the small fishes that make up their diet as they swim in the clear turquoise waters a few feet below. Watching these birds diving off the dock after a fish is nearly as entertaining as watching brown pelicans dive off the jetty at Sandy Point.

Royal Tern, Long Dock Cherokee Abaco Bahamas (Keith Salvesen)

There are buoys in the bay as well, and individual birds will fly from the dock to perch on a buoy and check out the fishing round it, before returning to the dock – hopefully with a fish in its beak. And the juveniles, with their endearing beginner ‘hair’styles (see #3) can learn the ropes from their elders and betters.

Royal Tern, Long Dock Cherokee Abaco Bahamas (Keith Salvesen)

People often stroll the length of the dock, or pause on it to pass the time of day and watch the optimistic bonefishers casting hopefully at their silver prizes. These fish are often easier to see from the dock than from wading level – people sometimes shout helpful encouragement: “There… going left…look!… 20 feet in front of you… no, THERE…” and so on. The terns take little notice of all this. A group of people, especially with a dog, might persuade the birds to take flight, but they return as soon as they can; or simple move along the dock and settle in a different place.

ABACO PARROT ACROBATICS


Abaco (Cuban) Parrot Acrobatics (Melissa Maura)

ABACO PARROT ACROBATICS

Melissa Maura is well-known to many in the Bahamas, not least because of the wonderful work she does with injured or orphaned creatures. Thanks to the skills and compassion of Melissa and those who work with her, animals and birds of all kinds are saved from death or incapacitating injury. In the saddest cases, they are gently cared for until the inevitable occurs.

Abaco (Cuban) Parrot Acrobatics (Melissa Maura)

Melissa also takes terrific bird photographs, some of which I have featured in the past. Indeed my blog headline photograph is one of her parrots. I used to change the header from time to time, but this one is so cheerful that I decided to keep it in place. It always makes me smile.

Abaco (Cuban) Parrot Acrobatics (Melissa Maura)

Parrots are acrobatic creatures, happy to eat at all angles including completely upside down. Not just eat, though. Also bicker, flirt, play-fight, and see off rivals via inverted aggression. With the Abaco parrots, one of the benefits for the bystander is that the balancing act and consequent fluttering often reveals the spectacular blue of the birds’ wings. 

Abaco (Cuban) Parrot Acrobatics (Melissa Maura)

In a row, it’s not unusual to see a parrot taking up a dominant position on a branch, leaving its opponent hanging on in an uncomfortably precarious position…

Abaco (Cuban) Parrot Acrobatics (Keith Salvesen))

People often ask where on Abaco they are most likely to see the parrots. First, there are no parrots north of Marsh Harbour – they are all in South Abaco. Secondly, although they live and nest in the National Park at the southern end of the island, in practice it covers a very large area, much of it inaccessible and with the only ‘road’ something of a challenge for an ordinary vehicle (described HERE). I’d say that the single most reliable place to see the parrots is at Bahama Palm Shores. Simple turn into the north entrance, drive straight down to the end with the windows down, park up – and listen. If they are there, you’ll hear them for sure!

RUFF & READY: YET ANOTHER BIRD FIRST FOR ABACO

RUFF & READY: YET ANOTHER BIRD FIRST FOR ABACO

The list of new bird species recorded for the Bahamas in general and Abaco in particular continues to grow longer. At the end of August it was a CANADA WARBLER (now also recently seen on Grand Bahama and possibly New Providence). Now, a mere 4 weeks later, it’s a Ruff (Calidris pugnax), a mid-sized Eurasian shorebird that, it seems, has a tendency to ‘vagrate’ across the Atlantic from time to time.

Ruffs: the normal range

Ruff, (N. America) Dick Daniels

You have to take new birds as you find them, of course. First, you may not have a camera with you to record the sighting for posterity. Secondly, the bird may not be perched prettily on a twig or a small rock. In this instance the legendary Woody Bracey found his Ruff in the prosaic and arguably unattractive setting of the Treasure Cay dump. He didn’t have a camera, and when he next went back with a camera to check for the bird the ruff had gone…

Ruff (m, non-breeding) J.M.Garg

Woody’s bird, a female (known as a Reeve), was standing next to a Lesser Yellowlegs. They are much the same height, but there the similarity ends – Ruffs are unmistakably plumper and with a shorter bill. Woody has good reason to recognise these rare and occasional transatlantic visitors, having often seen Ruffs both during his time living in the UK, and also in Africa. I’ve seen the appearance described as “like a gravy-boat”, which is well up there with the least useful descriptions of a bird’s appearance I have come across. Looked at another way, we have a couple of gravy boats that have an occasional outing. Neither looks remotely like a ruff.

IS THE ABACO RUFF A NEW SPECIES FOR THE WHOLE BAHAMAS?

Very nearly… but not quite. Only two previous Ruff sightings are recorded, in 2015 and 2018, and both in the same area on Grand Bahama, towards West End. And the only photo is from birder Duncan Mullis, who in 2015 took the first and maybe only one of a Reeve with a bunch of much smaller sanderlings (see also header image close-up).

WHAT SHOULD WE KNOW ABOUT RUFFS?

In the breeding season in particular, male ruffs are very different from the smaller reeves. They acquire a spectacular colourful plumage that includes a sort of ornamental collar (hence the name). They enhance their courtship rituals with elaborate displays designed to impress the reeves. These occur in chosen areas known as leks, places where strutting, preening and general competitive showing off occur to attract a mate. Such arenas are also created by a few other bird species – grouse, blackcock and peafowl, for example. The ruff’s lekking behaviour has some complex variations – including same-sex ‘copulation’ and polyandry – but sadly this isn’t the place to explore them in detail.

WHAT DOES A LEK LOOK LIKE?

Here are two males with very different breeding plumages, giving it their all at the lek… When Carl Linnaeus described the ruff in his Systema Naturae, he gave it the binomial name Tringa pugnax, the latter word meaning  ‘aggressive’ – the lek can also become a combat zone between competing males.

Ruff Lek (Arjan Haverkamp) wiki

This male has decided to vogue it and ‘strike the pose’ as it preensRuff - male preening (B.S.Thurner-hof, wiki)

Writing in The Spruce, a new multi-interest resource I discovered in researching this article, Melissa Mayntz describes succinctly some of the common behaviour seen at leks. This includes some (or all) of the following (baby-boomers and dad-dancers may recognise some of these moves):

  • Bowing, dipping, or bending
  • Head bobbing or quick turns and nods
  • Strutting, stomping, kicks, or similar footwork
  • Exaggerated wing postures, such as fluttering, drooping, or spreading wings
  • Tails fanned, flared, cocked, or spread
  • Chests puffed out, often to reveal air sacs or distinct plumage
  • Calling, songs, drumming, or booming sounds
  • Dance-like sequences with multiple movements, possibly coordinated between partners after a female shows an interest in a specific mate

To which I’d add aggressive male territorial rivalry within the lek, leading to physical attacks with beak, claws and wings. Meanwhile the females watch from the edge to assess their chosen mates. The illustration below shows this rather charmingly.

Illustration of a lek by Johann Friedrich Naumann (1780–1857)Ruff Lek - Johannes Naumann

There’s a lot to be described about how ruff’s moult, but it’s not especially interesting for anyone but a moult specialist, so instead you can have a reminder of Ogden Nash’s last word on the topic: ‘The song of canaries / Never varies / And when they are moulting / They are pretty revolting…’ And we’ll leave migration as well, since basically that factor is N/A for our particular part of the world.
♦ ♦ ♦ ♦ ♦
JUST OUT OF CURIOSITY, CAN YOU EAT RUFFS / REEVES?
In former times ruffs were considered a delicacy and were eaten in large numbers. Often they would be fattened in pens in preparation for the table. I’ll finish with an old description: 
…if expedition is required, sugar is added, which will make them in a fortnight’s time a lump of fat: they then sell for two shillings or half-a-crown a piece… The method of killing them is by cutting off their head with a pair of ‘scissars’, the quantity of blood that issues is very great, considering the size of the bird. They are dressed like the Woodcock, with their intestines; and, when killed at the critical time, say the Epicures, are reckoned the most delicious of all morsels. Not a 21st century culinary trend I hope…

COOTS FIGHTING & THE CARIBBEAN COOT DEFEATED


Coots Fighting (Phil Lanoue)

COOTS FIGHTING & THE CARIBBEAN COOT DEFEATED

These coot fight images are from Phil Lanoue, whom I have featured before. He is a master of bird sequences, magicking a whole avian story or drama in a few clear, sharp photos. These types of image are well beyond my skills and my camera limitations. Here are 2 males battling over a female which, by the final aggressive image in which dominance is asserted, has disappeared for the picture…

Coots Fighting (Phil Lanoue)Coots Fighting (Phil Lanoue)Coots Fighting (Phil Lanoue)

The other battle in Coot World occurred in 2016 when the endemic Caribbean Coot (formerly Fulica caribaea) was defeated by the combined forces of the American Coot (Fulica americana) and the all-powerful AOU, official arbiter of bird categorisation. They are now joined as a single species, the differences between the two types being considered insufficient to warrant separate species status. The familiar American version looks like this (note the red area on the shield above the beak):

American Coot - Bahamas - Great Abaco - Gerlinde Taurer

The ex-Caribbean Coot, has white frontal shield that extends to the top of the head. When I was compiling ‘Birds of Abaco‘ in 2013, there was already a question mark over the separate species status, with many regarding it as a sub-species of the American Coot. I wrote: There is an intriguing debate, a small book in itself, about the existence as a distinct species of the Caribbean Coot, with its white frontal shield. Many field guides include it separately, some with the rider that it is ‘unrecorded in the Bahamas’. The Bahamas Bird Records Committee does not recognise it, and Hallett, among other experts, views it simply as an American Coot variant. The image below of the two coots together is included to illustrate the visible difference between the birds. The genetic debate is fortunately outside the scope of this book”. That said, I pigheadedly went ahead and included it as a separate species anyway… 

An ex-Caribbean coot, with its white frontal shield.  Since 2016, just another coot'Caribbean' (now American' Coot - white frontal shield - Abaco, Bahamas. Woody Bracey

The research that led to the reclassification was based on the fact that breeding biology suggests that different species favour their own species for breeding. Research by Douglas McNair and Carol Cramer-Burke indicated that there is little or no ‘reproductive isolation’ of the sort to be expected in different species. The coots had no particular preference in their choice of mate. Also, they sound alike.

A HAIRY WOODPECKER ON ABACO, BAHAMAS


Hairy Woodpecker, Abaco Bahamas (Tom Sheley)

It’s Friday. I’ve just nixed for wild brown trout on the River Frome in the rain. I need a beer and I’ve run out of week. You can read more about the attractive little Hairy Woodpecker – Abaco’s small counterpart to the larger and noisier West-Indian Woodpecker – HERE. Have a good weekend!

PRESENTING A LARGE BILL… ANIS ON ABACO


Smooth-billed Ani, TCGC Hole 11 - Becky Marvil

PRESENTING A LARGE BILL… ANIS ON ABACO

The Smooth-billed Ani (Crotophaga ani) is the third member of the cuckoo family found on Abaco, the others being the MANGROVE CUCKOOand 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 and squawking, and fluttering around. You’ll probably hear them from some way off, sounding like this:

Smooth-billed Anis_Abaco - Tony Hepburn

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.
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.

Smooth-billed Ani. Abaco Bahamas Tom Sheley

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”.

Smooth Billed Ani, Abaco - Nina Henry 1a

“One… is the loneliest number…” Oh, hang on a moment…Smooth-billed Ani Abaco - Gerlinde Taurer a

…”two of us…standing solo in the sun…”Smooth-billed Ani, Abaco (Gerlinde Taurer) b

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. Any suggestions welcome. Meanwhile I put forward A Commotion of Anis”

NORTHERN PARULAS: ON THEIR WAY TO ABACO


The Northern Parula is one of 37 warbler species recorded for Abaco. The vast majority of these species are migratory, arriving in the Fall and leaving in the Spring to fly north to the breeding grounds. When I’m back at HQ from my computer-free break, I’ll be writing more about these little birds. Meanwhile, this post is a reminder that the influx will begin very soon. The Northern Parula, with the distinctive green patch on its back, is sure to be among them.

I’m away for a few days on the Emerald Isle, leaving my trusty computer many miles away (on purpose, I mean). I’ve just got my iPhone, but writing posts and inserting images on such a small screen / keyboard is a fool’s errand. So I’ve pre-loaded a couple of beautiful bird images to post this week. Here is a wonderful red-winged blackbird male taken by photographer Tom Sheley while we were getting together some images for The Birds of Abaco deep in Abaco backcountry.

BANANAQUITS: SMART BIRDS ON ABACO

BANANAQUITS: SMART BIRDS ON ABACO

Bananaquits are smart. They look smart, of course, and they act smart too. Their diet consists  mainly of nectar and fruit, so you’ll find them where there are flowering or fruiting trees and shrubs. Their sharp little beak curves slightly, enabling them to get right into where the good things are, as shown in this sequence of not-especially-good-so-I’ll-call-them-illustrative photos. And that beak gives then another method of reaching nectar – they can pierce the base of a flower and use the beak as a sort of probe to get at the nectar that way. And soft fruit? Easy!

‘ON STILTS’: ELEGANCE ON TWO LEGS (OR JUST ONE)


Black-necked Stilts, Abaco Bahamas (Keith Salvesen)‘ON STILTS’: ELEGANCE ON TWO LEGS (OR JUST ONE)

There’s something wrong in the picture above (no, I don’t mean about the photograph itself). Count up how many pink legs you can see. No, not including the reflections. Give up? It’s three. Between two birds. I assumed of course that  ‘Oner’ had a perfectly good serviceable leg tucked up into its undercarriage. I admired the balancing skills involved in resting one leg while nonchalantly standing on the other.

We were watching this pair of black-necked stilts Himantopus mexicanus at the pond at Gilpin Point, which at certain times can be ‘Stilt Central’. These birds are permanent breeders on Abaco and are without a doubt the most beautiful of all the waders (avocets, being extremely uncommon winter visitors, are disqualified from consideration for lack of presence). 

Black-necked Stilts, Abaco Bahamas (Keith Salvesen)
It gradually dawned on me that Oner really did only have one stilt to stand on. After 10 minutes observing them and the other birds around them, there was no question about it – the right leg was completely and utterly missing. This unipedal deficit had no obvious ill-effects on the bird – nor on its ability to throw a good pose (above). Or to preen (below).
Black-necked Stilts, Abaco Bahamas (Keith Salvesen)
I’m in danger of losing sight of Twoer here, a bipedal bird that deserves its own place in the story, not just a wade-on part in Oner’s story.
Twoer as Ringmaster…Black-necked Stilts, Abaco Bahamas (Keith Salvesen)
BNSs are territorial and in particular can become ‘proactive’ (ie aggressive) in protecting the area near a nest. I once mistakenly got close to a nest, not even knowing it was there. I soon learnt – a parent BNS came wading towards me, zigzagging in the water, shouting and carrying on in a way that immediately said ‘my nest is nearby’. And when I meanly stood my ground it suddenly took off and flew straight at my head…

WHERE’S THE CATCH? A REDDISH EGRET FISHING


Reddish Egret Fishing, Crossing Rocks, Abaco (Keith Salvesen)

WHERE’S THE CATCH? A REDDISH EGRET FISHING

The narrowest point on Abaco is just north of Crossing Rocks. The 120-mile long highway that splits the Island down the middle passes over a narrow strip of land. On the west side, there are mangrove swamps, an inlet of sea, and a small jetty used by bonefishers to reach the productive waters further out. On the east side? Well, there’s more mangrove swamp, giving way to thick jungly coppice before reching the top end of Crossing Rocks beach – and not much else. Except for a long thin brackish pond by the road, that is. 

Reddish Egret Fishing, Crossing Rocks, Abaco (Keith Salvesen)

If you are interested in birds – maybe on your way to the pond at Gilpin Point for Bahama Duck and waders, or returning from a Bahama mockingbird hunt in the National Park – it’s worth pulling over at the pond. Or preferably on the other side of the road so you can approach it stealthily. There’s plenty of roadside cover for birder discretion. Chances are, you’ll encounter one or more of the several heron or egret species found on Abaco – and that they’ll be fishing.

Reddish Egret Fishing, Crossing Rocks, Abaco (Keith Salvesen)

You can see how clear the water can be. It’s no wonder that this reddish egret has ‘hunched up’ to get that cruel beak closer to the surface to stab down on a small silver snack. In the short time we watched, he had no success (hence ‘Where’s the Catch?’ – there was none). But I’ve seen reddish egrets including the white morph successfully snacking at the pond; and a tricolored heron. A couple of years ago we had a great scoop in late March – a male reddish egret fishing in his wonderful breeding colours. Compare the ‘routine’ plumage of the bird above with this gorgeous creature.

So here’s something (even) more interesting than the stuff I write – actual photos of actual birds with no words. Great photos (not mine) of Abaco’s 3 cuckoo species to compare and contrast. Until next month… when there’ll be stilts, hutias and a whole lot more.

LOGGERHEAD KINGBIRD: BENIGN ‘TYRANT’ OF ABACO


Loggerhead Kingbird, Abaco Bahamas (Keith Salvesen)

LOGGERHEAD KINGBIRD: BENIGN ‘TYRANT’ OF ABACO

Abaco is home to 4 main so-called tyrant flycatchers (Tyrannidae): the loggerhead kingbird, the gray kingbird, the La Sagra’s flycatcher and the Cuban pewee. All are common permanent residents except the gray kingbird, which is a summer resident only. Several other flycatcher species are found on Abaco, but they are very uncommon winter residents, rare transients, or vagrants.

Loggerhead Kingbird, Abaco Bahamas (Keith Salvesen)

The loggerhead featured here in several poses is a watchful sentinel at Delphi. His preferred perches are in the edge of the coppice round the pool or at the edge of the main drive. From time to time he will leave his perch to catch a passing insect by ‘hawking’, returning to the same place to eat it.

Loggerhead Kingbird, Abaco Bahamas (Keith Salvesen)

Loggerhead and gray kingbirds can be quite easy to confuse. A couple of years ago I wrote about how to distinguish them, and with gray kingbirds in residence now this is probably a good time to set out the distinctions again.

Loggerhead Kingbird, Abaco Bahamas (Keith Salvesen)

LOGGERHEAD Tyrannus caudifasciatus vs GRAY Tyrannus dominicensis 

DIFFERENCES and SIMILARITIES

TOP TIP ANY KINGBIRD SEEN IN WINTER WILL BE A LOGGERHEAD

  • Kingbirds seen between (say) October & March are Loggerheads. Grays are strictly summer visitors
  • Both are medium size birds and roughly the same size as adults (around 23 cms)
  • Loggerheads have dark brown to near-black heads, grays have lighter, slate-coloured heads
  • Loggerheads have a ‘squared’ tip to the tail; grays have a notched tip
  • Loggerheads may have a whitish fringe at the tip of the tail; grays not so
  • Loggerheads have yellowish tinges to their white undersides & forewings; grays less so or not at all
  • Grays have a dark or black ‘mask’ through the eyes, often clear but not always easy to see
  • Loggerheads allegedly have inconspicuous orange head crests; grays are red. I’ve never seen either!
  • [*RH personal opinion alert*] Grays have larger, heavier beaks than loggerheads
  • Grays are territorially aggressive; when they turn up, the loggerheads tend to retreat to the forest
