KIRTLAND’S WARBLERS: DESERVING PHILATLEY…

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.

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.

SANDHILL CRANE: ABACO’S NOVELTY BIRD (2)


Sandhill Crane Antigone canadensis Abaco, Bahamas (Christopher Johnson) SANDHILL CRANE: ABACO’S NOVELTY BIRD (2)

In mid-December, Kaderin Mills of the Bahamas National Trust saw Abaco’s first-ever reported Sandhill Crane (Antigone canadensis) in the Fox Town area of North Abaco. Woody Bracey was quickly onto the news and in the afternoon he took photos of the bird. I posted about this exciting (because a new species is always exciting) event, with details about its significance plus facts, maps etc HERE

Six weeks later, the crane is still in residence. In the meantime a number of birders have been to see the new novelty bird for Abaco in what has become a small but significant birding hotspot right at the top end of the island, in area round the Church, the Primary School, and the Clinic. The crane is now firmly on the eBird map for the Bahamas.

    

Sandhill Crane Antigone canadensis Abaco, Bahamas (Woody Bracey)

This elegant visitor seems to be quite tame and unfazed by its new fame. People watch while it forages for invertebrates in the grass, pausing to check on bystanders before resuming its feeding. It tolerates the presence of humans without showing fear, let alone flying away.

Sandhill Crane Antigone canadensis Abaco, Bahamas (Erika Gates / Martha Cartwright)

The call of the Sandhill Crane sounds like this:

To test its reaction, a recording was played and immediately the crane responded and called out to the (apparent) co-crane. The bird has also (rather sadly?) been seen by locals by the door of the Church, looking at its reflection and even making pecking motions at it. A lonely crane, maybe.

.Sandhill Crane Antigone canadensis Abaco, Bahamas (Woody Bracey)

This bird is likely to remain disappointed by any expectation or hope of company. With any luck in the Spring, the instinctive call to the north (Canada and nearby US) will persuade it to migrate back to sandhill habitat to join a flock in the summer breeding grounds.

Sandhill Crane Antigone canadensis Abaco, Bahamas (Woody Bracey)

It is always a somewhat melancholy occurrence when a fine bird like this – or like last season’s lone BALD EAGLE – takes a wrong turn on their migration or perhaps get blown off course and finds itself on its own, species-wise. This bird seems to be taking it in its (longish) stride, however, and it has become something of a celebrity avian for the local folk. It will be interesting to find out when the migration urge finally encourages its flight away from its unusual overwintering habitat.

Abstract Flamingos

It is an ill-concealed secret that I don’t have an artistic bone in my body – I get acute angst if asked to draw a stickman. As I was looking through photos of large pink flamingo groups, I suddenly realised that I was getting some sort of abstract vision of them. Whoooh! Art-talk. Anyway, I wondered how a legion of flamingos might look in B&W. Add a bit of highlight and… does it work at all? Whether yes or no, this may be the only B&W photo of flamingos since the invention of colour film. Why would you? [Impatient reader: ‘Why did you?]

‘CARRION SCAVENGING’ (2): TURKEY VULTURES ON ABACO


Turkey Vulture, Abaco Bahamas (Nina Henry)

‘CARRION SCAVENGING’: TURKEY VULTURES ON ABACO

Turkey Vultures (Cathartes aura) are causing some comment on FB at the moment, in particular about why they like to stand on utility posts with their wings spread out wide. So, bending my flexible rule against reposts, I am updating a very old TUVU post with lots of new images and facts about this fascinating bird, which manages to be simultaneously majestic, hideous, revolting and socially vital, all packed into a single species…

turkey-vulture

The TUVU is 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)

Of those, 57% are taken in unhelpful light, and look like the one below. On the positive side, this picture show the extreme delicacy of the wing-tip feathering that enables these birds to adjust their direction and speed (this is not the bird above; it was taken by someone else at a different time. But 100% of TUVU in-flight photos are indistinguishable).

Turkey Vulture Abaco Bahamas (Keith Salvesen)

TUVUs have a wide range in the Americas and the Caribbean, and can prosper in almost any type of habitat. This is probably because these large birds are almost exclusively carrion feeders, and carrion is everywhere. They spend their days scavenging, or thinking about scavenging. 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 the scent of decay (and consequent release of the chemical ethyl mercaptan) from some distance. A breeding pair will raise two chicks, which revoltingly are fed by the regurgitation of all the rank… excuse me a moment while I… I feel a little bit… ~~~~~~~~~~~ …alright, OK again now.

Turkey Vulture Abaco Bahamas (Keith Salvesen)

When they are not flying, feeding, breeding or feeding 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 hiss (at 10 / 15 secs).

These vultures are often seen in a spread-winged stance, which is believed to serve multiple 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.

10 SCAVENGED TURKEY VULTURE FACTS FOR YOU TO PICK OVER

  • One local name for TVs 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
  • TVs 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 Turkey Vulture is gregarious and roosts in large community groups
  • The Turkey Vulture 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 MSS (missing septum syndrome). They tend to ‘sniff’ a lot]

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…

Turkey Vulture with carrion (wiki)

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”

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…

YELLOWLEGS (LESSER) ON ABACO: OUT STANDING IN THE WATER

YELLOWLEGS (LESSER) ON ABACO: OUT STANDING IN THE WATER

It’s always helpful when a bird ends up with a descriptive name (after translation from the Latin binomial) that actually matches the creature. Burrowing owl, Roseate Spoonbill, White-crowned pigeon, Red-legged Thrush, Black-and-white Warbler – you know where you are at once. So it is with the Yellowlegs, the only question being whether the one you are looking at is ‘greater’ (Tringa melanoleuca) or ‘lesser’ (Tringa flavipes). Both are found on Abaco, and a single bird on its own – with no size comparison – can be a potential source of confusion.  

Lesser Yellowlegs Tringa flavipes, Abaco Bahamas (Tom Sheley)

This last post for 2018 features the lesser yellowlegs, a winter resident, a rather off-beat choice you may think. The reason is that in clearing out some archive folders, I found some LEYE images in the wrong album. They reminded me what lovely birds they are when photographed well (so, not by me), with the subtle sheen of their plumage contrasting with their Malvolio-yellow legs.

Apart from size, the greater and lesser yellowlegs have some not-necessarily-very-noticeable differences in bill length (in comparison with head-size), plumage and vocalisation. Here is an excellent example of the yellowlegs cousins together, to give you a comparison.

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!

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.

SANDHILL CRANE: ANOTHER NEW BIRD FOR ABACO, BAHAMAS


Sandhill Crane, Abaco Bahamas - a first-ever sighting (Elwood Bracey)

SANDHILL CRANE: ANOTHER NEW BIRD FOR ABACO, BAHAMAS

Still they keep arriving, the new birds that have never before graced the shores of Abaco Recently it was a Canada warbler, at the lower end of the size scale. The elegant sandhill crane (Antigone canadensis) is the 10th new species for Abaco since the publication of The Birds of Abaco in March 2014. If you are wondering why the bird is not called Grus canadensis any longer, it’s because the genus of the bird was reclassified by the ABA in 2016. Out with dreary old Grus and in with exciting Oedipus’s daughter (or was she his half-sister? They… erm… had the same mother… Discuss, using both sides of the exam paper) in Greek mythology…

As the crane’s canadensis suggests and as range map shows, these are birds of North America, breeding mainly in Canada. In winter they head south to the warmth, reaching Florida as winter migrants. As you can see, the northern part of Florida and also Cuba have small year-round breeding populations. Zero zilch zip nada in the Bahamas.

THE ABACO SIGHTINGS, DECEMBER 2018

Sandhill Crane, Abaco Bahamas - a first-ever sighting (Kaderin Mills)

At 9.00 am on December 13, the bird above was photographed by Kaderin Mills (of the Bahamas National Trust) on Little Abaco, at the Fox Town Primary School, Crown Haven. The day before, the 12th, the school Principal Mrs Curry had seen the bird in the school grounds feeding on the grass. A couple of phone ‘sighting shots’ were taken before it flew off. Next day it returned, word spread and Kadie Mills recorded the bird officially and put it on eBird to give the newcomer some due publicity. By the early afternoon, Woody Bracey had been told about the bird, and went to take photos. He saw it in the same place the next day too.

Sandhill Crane, Abaco Bahamas - a first-ever sighting (Elwood Bracey)

OK, FIRST FOR ABACO – AND THE BAHAMAS TOO?

The strict answer is, no. Many years ago, there was a single report of a Sandhill Crane on Andros. It’s not known if the sighting was officially confirmed, but according to expert Bruce Hallett there was a photograph, and the late Tony White, then ‘recorder’ for the Bahamas, saw it. There are no available records, but Tony’s authority on issues around Bahamas birds was (and remains) absolute.

Sandhill Crane, Abaco Bahamas - a first-ever sighting (Elwood Bracey)

12 CAREFULLY SELECTED SANDHILL CRANE FACTS

  • These cranes are social birds, usually living in pairs or in family groups 
  • Their calls are loud and far-reaching, like a huge crows with a sore throat (below) 
  • Mated pairs engage in ‘unison calling’, standing close and duetting amorously
  • Hatchlings are fully-formed and can leave the nest within a day.
  • Juveniles are known as colts (whichever their gender, it seems)
  • They have an impressive wingspan as adults, from about 5′ to 7′ 6″
  • They are able to soar in flight, using thermals to obtain lift and stay aloft for hours
  • Flocks of cranes may be huge – sometimes estimated at over 10,000 individuals
  • Their ancestors are among the oldest fossils of any bird species, at around 2.5 M  years
  • Vagrants have been found as far off piste as Britain (1981, 1991 only), China and Japan
  • Many predators call them dinner; but they can kick and stab with their bills in defence
  • The sandhills of Cuba form the smallest breeding population, around 300
