THE DELPHI CLUB GUIDE TO THE BIRDS OF ABACO by KEITH SALVESEN – a few copies now available

Delphi Club Guide to the Birds of Abaco (Jacket)

THE DELPHI CLUB GUIDE TO THE BIRDS OF ABACO

BIRDS OF ABACO was launched at the Delphi Club, Abaco, Bahamas in March 2014. I thought all copies had been sold or donated ages ago. In the aftermath of Hurricane Dorian in 2019, a number of Abaconians asked if I could replace their ruined copies. Sadly I could not. Or so I thought. A current blitz to clear our house (40 years-worth of stuff) has unearthed 2 boxes of the book, so I have decided to sell them. Scroll to the end for further details. First, though, check out these birds… The originator of the idea for the book – as with the entire Delphi Club project – was Peter Mantle, the publisher. He took a risk based on my (then) quite feeble Rolling Harbour blog about the birds and other attractions of the island. The 2kg book took 16 months from conception to the arrival of three pallets of printed books on the dockside in Marsh Harbour, having travelled by a tortuous route from specialist printers in Italy.

As part of the project, Abaco schools, libraries and wildlife organisations were given copies for educational purposes. A percentage of profits was given to local wildlife causes. We quickly sold a great many copies, and couldn’t have been more pleased with the response to the book, a unique publication for the Bahamas. The captions (below) about the book and content were written much nearer the time, so I’ll leave them as they are. I hope you enjoy the photos even if you don’t want a copy!

Short-billed Dowitcher, Abaco (Bruce Hallett)

The Guide showcases the rich and varied bird life of Abaco, Bahamas and features both resident and migratory species including rarities and unusual sightings. The main features are as follows:

272 pages with more than 350 photographs
163 species shown in vivid colour – nearly two-thirds of all the bird species ever recorded for Abaco
Every single photograph was taken on Abaco or in Abaco waters
All birds are shown in their natural surroundings – no feeders or seed trails were used
Several birds featured are the first ones ever recorded for Abaco or even for the entire Bahamas

A total of 30 photographers, both experienced and amateur, contributed to the project
The book has had the generous support of many well-known names of Abaco and Bahamas birding
A complete checklist of every bird recorded for Abaco since 1950 up to the date of publication was compiled specially for the book.
A neat code was devised to show at a glance when you may see a particular bird, and the likelihood of doing so. Birds found at Delphi are also marked.

Informative captions intentionally depart from the standard field guide approach…
…as does the listing of the birds in alphabetical rather than scientific order
Say goodbye to ’37 warbler species on consecutive pages’ misery
Say hello to astonishing and unexpected juxtapositions of species

The book was printed in Florence, Italy by specialist printers on Grade-1 quality paper
Printing took pairs of printers working in 6 hour shifts 33 hours over 3 days to complete
The project manager and the author personally oversaw the printing

The book is dedicated to the wildlife organisations of Abaco
A percentage of the proceeds of sale will be donated for the support of local wildlife organisations
A copy of the book has been presented to every school and library on Abaco

The book is published by the Delphi Club. The project was managed by a publishing specialist in art and architecture books. The author is the wildlife blogger more widely known on Abaco and (possibly) beyond as ‘Rolling Harbour’. Oh! So that would in fact be Mrs Harbour and myself. Well well! What were the chances?

THE ORIGINAL FLYER

FLAMINGO TONGUE SNAILS: DECORATIVE CORAL-DWELLERS

April 20, 2021 by Rolling Harbour

FLAMINGO TONGUE SNAILS: DECORATIVE CORAL-DWELLERS

FLAMINGO TONGUE SNAILS Cyphoma gibbous are small marine gastropod molluscs related to cowries. The living animal is brightly coloured and strikingly patterned, but that colour only exists in the ‘live’ parts – the so-called ‘mantle’. The shell itself is usually pale, and characterised by a thick ridge round the middle. These snails live in the tropical waters of the Caribbean and the wider western Atlantic. Whether alive or dead, they are gratifyingly easy to identify.

Flamingo Tongue Snails (Melinda Rogers, Dive Abaco, Bahamas)

THE IMPORTANCE OF CORAL

Flamingo tongue snails feed by browsing on soft corals. Often, they will leave tracks behind them on the coral stems as they forage (see image below). But corals are not only food – they provide the ideal sites for the creature’s breeding cycle.

Adult females attach eggs to coral which they have recently fed upon. About 10 days later, the larvae hatch. They eventually settle onto other gorgonian corals such as Sea Fans. Juveniles tend to live on the underside of coral branches, while adults are far more visible and mobile. Where the snail leaves a feeding scar, the corals can regrow the polyps, and therefore the snail’s feeding preference is generally not harmful to the coral.

The principal purpose of the patterned mantle of tissue over the shell is to act as the creature’s breathing apparatus. The tissue absorbs oxygen and releases carbon dioxide. As it has been (unkindly?) described, the mantle is “basically their lungs, stretched out over their rather boring-looking shell”.

THREATS AND DEFENCE

The species, once common, is becoming rarer. The natural predators include hogfish, pufferfish and spiny lobsters, though the spotted mantle provides some defence by being rather unpalatable. Gorgonian corals contain natural toxins, and instead of secreting these after feeding, the snail stores them. This supplements the defence provided by its APOSEMATIC COLORATION, the vivid colour and /or pattern warning sign to predators found in many animal species.

MANKIND’S CONTRIBUTION

It comes as little surprise to learn that man is now considered to be the greatest menace to these little creatures, and the reason for their significant decline in numbers. The threat comes from snorkelers and divers who mistakenly / ignorantly think that the colour of the mantle is the actual shell of the animal, collect up a whole bunch from the reef, and in due course are left with… dead snails and “boring-looking shells” (see photos below). Don’t be a collector; be a protector…

The photos below are of nude flamingo tongue shells from the Delphi Club Collection. Until I read the ‘boring-looking shell’ comment, I believed everyone thought they were rather lovely… I did, anyway. You decide!

WHITE-CHEEKED PINTAILS and BAHAMA DUCKLINGS

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

BANANAQUIT (Coereba flaveola) Abaco, Bahamas

March 15, 2021 by Rolling Harbour

Bananaquits (Coereba flaveola) are small, colourful, and delightful birds of the coppice and garden. They have also managed to generate one of the most complicated taxonomic conundrums in the whole of bird land. I’ll spare you the varied classification details, which include warbler, bunting, tanager, monotype (unique), and the uncomfortably vague incertae sedis (= ‘uncertain group‘).

*Bananaquit . Abaco . Bahamas . Yellow elder (National Flower)*

Luckily, they are oblivious to all this controversy. Whatever their family background, Bananaquits will always be one of the most appealing small birds you’ll ever encounter. They are certainly high in the rankings of my own generalised designation ‘pretty little bird’ (Avis bellusparvus)

ATLANTIC SPOTTED DOLPHINS . ABACO BAHAMAS

ATLANTIC SPOTTED DOLPHINS – ABACO, BAHAMAS

There’s never ever a wrong time for dolphins to have some fun in the water. It’s what they expect. It’s what we (if we are lucky enough to see them) expect. It’s what they expect that we expect if we are out in a boat – hence the joyful bow-riding, the rapid crossing back and forth. From time to time there’s a single dolphin in a group that takes the opportunity to show off. In the deeper water off the southern tip of Abaco, in sight of the lighthouse, this is a good example of such carefree behaviour.

There’s more excitement to be found in this group. If you look carefully at #3 in the gallery, you’ll see a very small dorsal fin. There’s a calf in the group, being guided and watched over by two adults. Imagine being out there in a boat and encountering this group. That would in itself be something to show off about…

BAHAMA WARBLERS ON ABACO

February 20, 2021 by Rolling Harbour

BAHAMA WARBLERS ON ABACO

The Bahama warbler Setophaga flavescens is a significant species in the Bahamas, not least because of their very confined range. These are speciality birds on Abaco, taking their place alongside just 4 other year-round resident warblers. In contrast, there are 33 recorded migratory or transient warbler species which begin to arrive in early spring and are mostly gone by October.

SPECIAL STATUS

Found only on Abaco and Grand Bahama
One of only 5 bird species endemic to the Bahamas
One of only 2 endemic warbler species on Abaco (with the BAHAMA YELLOWTHROAT)
One of only 5 permanent year-round resident warblers (33 others are migratory), the other 3 being the OLIVE-CAPPED, YELLOW, and PINE warblers.

YELLOW-BELLIED SAPSUCKER

February 11, 2021 by Rolling Harbour

I have just been asked about image rights for a Yellow-bellied sapsucker Sphyrapicus varius featured in BIRDS OF ABACO so I have gone back to the archive. The photograph below was taken by Gerlinde Taurer, a significant contributor to the book. On Abaco the sapsucker is the only migratory woodpecker species, a fairly common winter resident. The two other woodpecker species – West Indian and Hairy – are year-round residents. Like its woodpecker cousins, the sapsucker drills holes in trees. The dual purpose is to release the sap (which it eats); and so to attract insects (which it also eats). A two-course meal, if you like. They’ll also eat insects on an undrilled tree, and even ‘hawk’ for them in flight. They sensibly balance their diet with fruit and berries. This is without doubt the best image of a YBS I have come across.

SEAHORSES: PREHENSILE TALES FROM THE REEF

It’s a while since I showcased these astonishing little creatures. Adam Rees of SCUBA WORKS is a diver who combines great underwater experience with wonderful photographic skills. Here is a showcase for some of Adam’s seahorse photography and the amazing detail he captures. If these images don’t make you want to get your head underwater and explore the reefs, I can’t think what will…

TUNICATES: SESSILE ASEXUAL SEA-SQUIRTS

January 15, 2021 by Rolling Harbour

TUNICATES: SESSILE ASEXUAL SEA-SQUIRTS

Painted Tunicates Clavina picta are one of several species of tunicate ‘sea-squirts’ found in Bahamas and Caribbean waters. These creatures with their translucent bodies are usually found clustered together, sometimes in very large groups. One reason for this is that they are ‘sessile’, unable to move from where they have taken root on the coral.

HOW DO THEY FEED?

Like most if not all sea squirts, tunicates are filter feeders. Their structure is simple, and enables them to draw water into their body cavity. In fact they have 2 openings, an ‘oral siphon’ to suck in water; and an exit called the ‘atrial siphon’. Tiny particles of food (e.g. plankton) are separated internally from the water by means of a tiny organ (‘branchial basket’) like a sieve. The water is then expelled.

Diagram of adult solitary tunicate

WHAT DOES ‘TUNICATE’ MEAN?

The creatures have a flexible protective covering referred to as a ‘tunic’. ‘Coveringcates’ didn’t really work as a name, so the tunic aspect became the name.

IF THEY CAN’T MOVE, HOW DO THEY… (erm…) REPRODUCE?

Tunicates are broadly speaking asexual. Once a colony has become attached to corals or sponges, they are able to ‘bud’, ie to produce clones to join the colony. These are like tiny tadpoles and their first task is to settle and attach themselves to something suitable – for life – using a sticky secretion. Apparently they do this head first, then in effect turn themselves upside down as they develop the internal bits and pieces they need for adult life. The colony grows because (*speculation alert*) the most obvious place for the ‘tadpoles’ to take root is presumably in the immediate area they were formed.

APART FROM BEING STATIONARY & ASEXUAL, ANY OTHER ATTRIBUTES?

Some types of tunicate contain particular chemicals that are related to those used to combat some forms of cancer and a number of viruses. So they have a potential use in medical treatments, in particular in helping to repair tissue damage.

CHRISTMAS TREE WORMS: SEASONAL SPIROBRANCHES

December 21, 2020 by Rolling Harbour

CHRISTMAS TREE WORMS: SEASONAL SPIROBRANCHES

“Deck the Reefs with Worms Like Christmas Trees… Fal-La-La-etc-etc ” is a traditional Carol familiar to all. Well, most. Ok, some, then. Oh right – maybe with different words? Anyway, now is the perfect time to take a look at these remarkable subsurface symbols of seasonal good cheer (nb they are wonderful animals not gorgeous plants).

10 CHRISTMAS TREE WORM FACTS TO PONDER

The 2 colourful spirals are not the worm, but complex structures for feeding & respiration
The spirals act as specialised mouth extensions for ‘filter-feeding’
Prey is trapped by the feathery tentacles & guided by cilia (microscopic hairs) to the mouth
The tentacle things are radioles and act as gills for breathing as well as prey traps
It is not believed that prey slide down the spiral to their doom, like on a helter-skelter

Christmas Tree Worm (Melinda Riger / Grand Bahama Scuba)

The actual worm lives in a sort of segmented tube, with extremely limited mobility skills
It contains digestive, circulatory & nervous systems – and a brain in the middle of it all
The worm also has a tiny drainage tube (I think I have this right) for excretion etc
They embed themselves into heads of coral such as brain coral. And stay there
And yes, the Christmas trees are retractable… (see below for some action)

HOW DO THE WORMS… YOU KNOW… ERM… REPRODUCE?

This is a delicate area. They are very discreet, but as far as I can make out they eject gametes from their what-I-said-above. There are mummy and daddy worms, and their respective gametes (eggs and spermatozoa) drift in the current and into each other to complete the union. The fertilised eggs develop into larvae, which settle onto coral and burrow into it as their parents did, build their protective tubes, and the process begins again.

YOU DON’T REALLY UNDERSTAND THESE CREATURES, DO YOU?

I won’t lie. I found it hard to work out how the CTWs function in practice. There are plenty of resources showing them in their full glory, but that only takes one so far. Then I came across a short video that shows it all brilliantly simply (except for the reproduction part).

The worms, in their coral burrows, hoist their pairs of ‘trees’. You can easily see small particles – zooplankton – drifting in the water, and the radioles swaying to catch potential food. Suddenly it all makes sense (except the repro bit – I haven’t found footage of that). Next: the New Year Worm (there is no Easter worm).

A WHOLE FESTIVAL OF CHRISTMAS TREE WORMS

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

December 18, 2020 by Rolling Harbour

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

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

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

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

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

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

Sandpiper, Semipalmated Plover, Ruddy Turnstone, Wilson’s Plover (all on Abaco)

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

Tuna on his vacation from Watching Bay to Winding Bay. Note meat string in #1

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

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

This is me back on my beach after my trip. Green on Blue (L); Black on Grey (R) = TUNA

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

More news from me soon. Cheeps from Tuna.

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

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

FIVE STARS: BAHAMAS ENDEMIC BIRDS (FOUR FROM ABACO)

FIVE STARS: BAHAMAS ENDEMIC BIRDS (FOUR FROM ABACO)

It’s December 2020, and Caribbean endemic birds are, deservedly, being given more time in the sun. Right now they are being featured by BNT (Bahamas National Trust); BirdsCaribbean; and (in an excellent Zoom presentation today) the august Linnean Society in Burlington House, London. So I am chiming in with slightly updated post on the topic, a reminder both of the beauty of the endemics and of their struggle for survival.

ABACO is fortunate to be home to 4 of the 5 endemic Bahamas species. The fifth, the beautiful BAHAMA ORIOLE Icterus northropi, was found on both Abaco and Andros until the 1990s, when it sadly became extirpated from Abaco. Now found only on Andros, until quite recently there were thought to be fewer than 300 Orioles left – a barely sustainable number. The species is unsurprisingly IUCN listed as critically endangered. However, there are signs that an intensive conservation program is working, with an increase in individuals and some new local populations found. Here’s a picture of one as a reminder of what Abaco is now missing…

Bahama Oriole – Daniel Belasco

Abaco’s four endemic species are the tiny Bahama Woodstar hummingbird, the Bahama Yellowthroat, the Bahama Warbler (since 2011), and the Bahama Swallow. All are of course permanent breeding residents on Abaco and its outer Cays. None is exclusive to Abaco; all are relatively plentiful. The Woodstar is perhaps the hardest to find, not least because it competes territorially with the Cuban Emerald hummingbird. Here are some striking images of these four endemic bird species taken from the archives for (and starring in) ‘The Birds of Abaco’ published in 2014

‘The Delphi Club Guide to the Birds of Abaco’ was published as limited edition, with additional copies donated to every school and relevant education department on Abaco, and to the conservation organisations. This tied in with the excellent policy of teaching children from a very early age the value of the natural world around them, the importance of its ecology, and the need for its conservation. The cover bird for the book was easy to choose – it just had to be a male Woodstar in all his glory with his splendid purple ‘gorget’.

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

December 1, 2020 by Rolling Harbour

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

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

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

Showing Rhonda my bands so she knows me

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

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

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

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

Joulter Cays, Andros, Sep 28. Thousands of shorebirds including over 100 PIPL. Including Paula.

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

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

“I’M WITH THE BAND…” PIPING PLOVER TUNA’S GUEST POST – revisited

November 26, 2020 by Rolling Harbour

“I’M WITH THE BAND…” PIPING PLOVER TUNA’S GUEST POST 1

ABACO PIPING PLOVER WATCH was an amateur ‘citizen science’ conservation program to help investigate the winter season migrations of a tiny shore bird. It started in August 2015 as a winter-season supplement to the serious scientific research carried out annually in the summer breeding grounds and during winter trips by Conserve Wildlife Foundation New Jersey and related organisations. The data collected by APPW during the 2015-16 season turned out to be significant, so much so that the Watch continued for 5 years until Hurricane Dorian struck in September 2019. There were a few sightings after that, but the lasting changes for the island and its people precluded bird-watching.

TUNA was the first banded bird we found, a summer chick that had completed a 1000+ mile flight when aged about 3 months. During the season, Tuna’s life on Abaco was monitored, in particular by Rhonda Pearce who bonded with the little bird and took lots of photos. Tuna asked, in a whimsical way, if I would make space for a Guest Post. This was the first.

Hello, readers of Mr Harbour’s blog. My name is Tuna. This is the first part of my autobiography, and I’m only just 3 months old. I’ve already made a 1000-mile journey to Abaco for reasons I don’t quite understand. Maybe because it’s nice and warm here. This is my story so far.

I was born on June 10th in the Holgate Unit of the Edwin B Forsythe National Wildlife Refuge, New Jersey. If I’d known then what ‘beautiful’ was, this would have been it.

My dad is called Ross. My mum is called Paula. I had a brother but suddenly he stopped being there. We didn’t see him again, I never knew why. Anyway, the day after I was born a very kind lady called Michelle (Stantial, CWF-NJ) picked me up and sort of cuddled me in her fingers. I was weighed and measured. She also put coloured rings on my top bits of leg. I had blue & green on one leg and black & gray on the other. Very smart. A chic chick. It was very quick and it didn’t hurt at all. After that I never really thought about them again, they just were part of me. As I grew bigger they sort of grew with me.

It made for an exciting first full day of my life, June 11. Here are some pictures of Michelle doing this with other chicks from the same region so you can see how gentle she was. The chicks’ names were Meg, Joe and Nod. Mr Northside Jim watched them every day and took photos of them to record how they grew up. You can read about us and the other shorebirds, Ospreys and Peregrine Falcons of LBI NJ HERE

I grew very quickly and my mum and dad showed me how to get food for myself. They looked after me in the nest and kept an eye on me when I went for a wander. Soon I was trying out my wings to see what would happen. Nothing.

This isn’t me but was taken quite near my bit of beach. Can you see the other chick?

It’s fun exploring the big world but it’s dangerous for little birds. I lost several friends along the way. That’s how my brother disappeared I think. As you grow bigger the world seems to get smaller. Which is weird.

I got good at finding my own food, going further away from the nest and trying out the water. My wings seemed to be starting to work a bit. Quite soon I felt nearly ready to have a go at flying.

On July 5 I managed to fly. Yup, I fledged and I flew. That was only 25 days after I cracked out. Mum and Dad had been talking about making a journey, a long one, and wondering when I would be ready for it. This was puzzling. I liked it where we were. But something was telling me I needed to fly somewhere else for some reason. Then one day I just took off and headed south…

After several days of flying and landing in new places to rest and flying again, I reached a place that I knew was exactly right. I don’t know how, but something told me that it would be a good place to stay until I needed to move again. So I landed on a beach called Watching Bay on Abaco. I’d travelled 1000 miles from where I cracked out, and I wasn’t even 3 months old. Cool, huh?

There were some other birds on the beach, including one just like me except she didn’t have any coloured rings. Ha! There were very few humans apart from a few taking a walk. On Aug 28 one lady stopped and pointed something at me. I wonder why? She kept her distance so I wasn’t scared.

There was plenty to eat on the beach, and it was quite sheltered from the wind. It seemed safe. I liked it a lot and decided to stay there

On Sep 16 I saw the same lady again, and she saw me. She was very careful not to get me worried, and she pointed that thing at me again. Then she walked away. I hope she comes back. She seems nice.

ROLLING + TROLLING

TROLLING

The hot news hereabouts is that my troll friend is back. I mention it not because it remotely bothers me but so that he? she? they? they all? will know that I have noticed. That must be the point. If I didn’t notice, all that effort working through my posts of the last 3 months would be wasted. Where’s the joy in that? So it’s kindest to let you know that I know that you know that I know. And well done you – it’s your second outing this year. It’s been twice a year for about 4 years, so it may be that the medication periodically wears off. Time for a top up, you may think. Meanwhile, you are more than welcome to comment on any post you find disagreeable or offensive. Natural History can be so aggravating, can it not?

THREE ‘HALLOWEEN-COLOURED’ BIRDS ON ABACO, BAHAMAS

October 31, 2020 by Rolling Harbour

THREE ‘HALLOWEEN-COLOURED’ BIRDS ON ABACO

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

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

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

AMERICAN REDSTART

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

BALTIMORE ORIOLE

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

WESTERN SPINDALIS

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

BOBOLINK (disallowed)

A possible Halloween candidate is the bobolink Dolichonyx oryzivorus. which is a transient species found from time to time on Abaco as they migrate from north to south (fall) and back again (spring). Disqualified because it spends so little time in Abaco; and because even my rather lax approach to categorisation recognises that the ‘orange’ is not very orange; and there’s not a great deal of it. Special credit mention, however, to Jim Carroll / Cornell Lab / Macaulay Library for this outstanding image)

No birds were hexed, vexed, tricked or even treated in the making of this post

WHALE TALES FROM BMMRO, ABACO BAHAMAS

WHALE TALES FROM BMMRO, ABACO BAHAMAS

These photos of tailing sperm whales Physeter macrocephalus were taken in the last month or so off the coast of South Abaco, close to the HQ of BMMRO (Bahamas Marine Mammal Research Organisation) at Sandy Point.

The powerful tails, or flukes, of the sperm whale are the largest of any whale species relative to body size. As the whales prepare for a deep dive, the flukes are the last thing you’ll see…

Marine mammals can be identified by individual characteristics such as tears to the fluke (whales – see header image), dorsal fin (dolphins) or ‘paddle’ (manatees). Many will be sighted and recorded, and later seen regularly, often for many years. Family dynasties can even be traced down the generations.

The whale above is in the final stages of a dive, just before the fluke slides beneath the surface and vanishes. The dramatic moments that precede this, with the unforgettable sight of water pouring off the spread tail – are over. The hunt for deep-down squid has begun in earnest.

PIPING PLOVERS: BAHAMAS RARE WINTER RESIDENTS

September 17, 2020 by Rolling Harbour

PIPING PLOVERS: BAHAMAS RARE WINTER RESIDENTS

‘ON A BEACH NEAR YOU’

PIPING PLOVERS Charadrius melodus are specialist shorebirds in the Bahamas, and on Abaco in particular. For a start, they are very rare – the IUCN listing suggests a population of only 8000 mature birds in the world. They are both scarce numerically and limited geographically.

September is the month when shorebirds get good publicity. World Shorebirds Day, Plover Appreciation Day, Migratory Birds Celebration Day, Ruddy Turnstone Tuesday and the like. Piping plovers are my particular pigeon, so I’m posting a revised article about them and their close migratory relationship with the Bahamas.

These tiny plovers breed only in a few defined areas of North America – areas that are rapidly reducing mostly for all the usual depressing human-derived causes, for example the exercise of man’s alienable right from time immemorial to drive vehicles all over the nesting sites in the breeding season. The birds are unsurprisingly IUCN listed as ‘near-threatened’.

Piping Plovers breed and nest in the north and produce their chicks. The chicks soon learn to be independent and to fly. From about mid-July, those adults and chicks that have avoided the wheels of the SUVs, the unleashed dogs in the areas set aside for nesting, and the more natural dangers from gulls and their friends, start to get the urge to fly south for the winter. The range of their winter grounds is shown in blue on the range map above.

Q. WHY ARE THEY CALLED PIPING PLOVERS? A. BECAUSE OF THIS!

Paul Turgeon

I will return at some stage to the significance of the safe, clean beaches of Abaco and the healthy habitat for the survival of this remarkable little bird. For now, I’ll simply say that loss of habitat, and an increase in the nature and / or extent of environmental threats at either end of the migration, may seriously damage the survival of the species. It follows that habitat degradation at both ends of the migration could see the IUCN listing progress rapidly to vulnerable, endangered, critically endangered and… well, the next category is ‘extinct in the wild’.

If you are interested in shorebirds, in bird migration, in research into bird movements, and in the reason migratory birds are banded, you can find out more at ABACO PIPING PLOVER WATCH.This is the only season-long PIPL research project in the Bahamas, and involves Citizen Scientists on Abaco in the south working with partner Proper Scientists (in particular Conserve Wildlife Foundation New Jersey) in the breeding grounds in the north (see note below re the end of this 5-year project).

The photographs in this post were taken in January 2020 on the long crescent of beach at Winding Bay, Abaco by Lisa Davies. Her contribution is precious because the APPW project mentioned above was for many reasons in danger of stalling as the result of the devastating effects of Hurricane Dorian on almost every aspect of island life. Lisa’s discovery of a small flock of a dozen plovers in the sunshine has given impetus to the project – and has resulted in some superb photos.

ABACO PIPING PLOVER WATCH: A POSTSCRIPT

This piece was posted in early January 2020, when no one could have predicted the current worldwide crisis. By then, Abaco Piping Plover Watch had basically ended on Sept 1 when Dorian wrought its havoc on Abaco with maximum force early in the season. By the end of the season, the Watch had been in action for 5 years and collected plenty of valuable migration data in conjunction with the breeding grounds. My own connection with Abaco had already lessened. Covid spread. It became clear, sadly, that the time was right to end the project.
