A WHITER SHADE OF TAIL? LEUCISM IN BIRDS

And not just the tail*. Other parts of a bird. Sometimes most of a bird. More rarely, an entire bird. Whichever, a bird affected by leucism stands out from the crowd – out of the ordinary and therefore startling to the eye. I’d be very surprised if the fine turkey vulture in the header image didn’t make you look twice – maybe even to check if some devious photoshop trickery had been at work. Yet it’s just a normal TUVU in the Florida Keys, living a normal vulturine life.

LEUCISM? EXCUSE ME, AND THAT IS?

First, what it is not. It is not albinism, which results from diminished or lost melanin production that affects pigmentation. One characteristic of the condition is the tendency to pink eyes, which of course is seen in humans as well as animals and birds. Meet the perfect example…

Albino Rabbit (pinterest)

WELL, WHAT IS IT THEN?

Put simply(ish), melanin is only one of many ingredients of pigmentation. Leucism is caused through pigment loss involving many types of pigment, not just melanin. In birds this results in unnaturally light or white colouring of feathers that may be partial or entire. The eyes of a bird with leucism are unaffected. At one extreme, if all pigment cells fail, a white bird will result; at the other extreme, pigment defects cause patches and blotches of pale or white on the bird, often called a ‘pied’ effect. The condition can be inherited.

BAHAMA (WHITE-CHEEKED) PINTAIL: A PIGMENT PUZZLE

I have found more examples of leucism in the ‘Bahama Duck’ than any other local species on Abaco. But there is also scope for confusion. First, here’s a pintail that is undoubtedly leucistic – note that the eyes and beak are unaffected by pigmentation deficiency:

Leucistic Bahama Pintail (Jim Edmonson)

But not all pale variants can be so confidently labelled. In the first picture, bottom right, there is an obviously an ‘odd’ pintail, silvery rather than ruddy brown like the rest of them (and yes, I do see the coot in the pack as well…). The second photo shows the same bird on dry land.

White-cheeked (Bahama) Pintail, Abaco 1 (Keith Salvesen) White-cheeked (Bahama) Pintail, Abaco 2 (Keith Salvesen)

This is known as a ‘silver pintail’. These are said to be a leuchistic variant, and they are stocked by poultry dealers as ornamental ducks at a higher price than the much-loved standard brown version. However this bird clearly retains the essential markings of a normal pintail that you might expect to be absent (at least in patches) in the ‘true’ leucistic bird. I’ve seen it described as a ‘gray morph’. I wonder where the line is drawn between a noticeable colour variant or morph in a bird; and an obviously pigment-abnormal, leucistic bird where the incidence and extent of the condition seems to be random. I’d go with the morph idea.

PIPING PLOVERS CAN BE LEUCISTIC TOO

PIPL are one of my bird species preoccupations, but until I checked them out I hadn’t imagined what a leucistic one would look like, or whether they had ever been recorded. I now have the answer… Leucistic Piping Plover (Audubon Alliance)leucistic plover 2leucistic plover 3

These photos of a leucistic female were featured by Audubon Alliance for Coastal Waterbirds, Audubon Connecticut. They were taken by Jim Panaccione, a Biological Science Technician at Parker River National Wildlife Refuge, Newburyport, Massachusetts. I hope he won’t mind their illustrative use here… Despite the theory that leucistic birds may find it hard to find a mate – and might even be attacked by its own species – this pair successfully nested.

PLOVER APPRECIATION DAY 2021


Wilson’s Plover . Abaco . Bahamas (π Craig Nash)

As so often I have missed by 2 days a crucial ‘International Day of the… Whatever’. This time we are celebrating plovers. This group of little shorebirds is appreciated every September 16, and they are high up in my favourites list. Here are examples of the 6 species that you will find on Abaco. Of these, most significant are the piping plovers that chose Abaco beaches – more than 1000 miles from their home beaches in the north – as their migration destination for overwintering (in fact, they start to arrive from the end of July and have left by mid- March).

PIPING PLOVERS

These rare little birds were the subject of a 5-year citizen science project on Abaco involving tracking banded birds sighted on Abaco beaches and tracing their origins to their home beach where the birds had hatched and and fledged. Much remarkable data was recorded, not least that many of the birds made the same journey from their home beach to Abaco and back in the spring 2, 3 and even 4 years running. Each time and at each end of the migration, they chose the same beach. Often the dates almost matched as well. You can find out more HERE

‘THE DITZY CHICKS’ & ‘THE BEACH BYRDS’: BANDS TO ADMIRE

WORLD SHOREBIRDS DAY  – PIPING PLOVER MIGRATION

Piping plovers are rare, tiny, unutterably cute, weigh about 2oz – and every Fall they fly south 1000 miles or more to warmer climes. Abaco is one such clime. The data collected during the 4 years of the ABACO PIPING PLOVER WATCH project shows annual counts of ±250 individual birds found either in flocks in specific hotspots, or more randomly in small groups, pairs or singles. Certain areas on the Cays are also popular. Of all these, around 10% have been banded in their breeding grounds, almost always as chicks – many with in a day or two of hatching.

‘CHEROKEE’

SQUID’S KIDS

To set the scene (the story is developed below). The 3 tiny chicks with the ring bling in the large photos hatched at a Wildlife Refuge in New Jersey about 10 days ago. Their parents are Squid and Sophie. The scientists who captured, weighed, measured and banded them also named them, for reasons which will become apparent, Keith, Cherokee and Abaco. This post aims to explain the background story, and in particular the great significance of banding as a tool of research into rare species.

At the outset – and because a few people express concern –  I’d better add that no deleterious effects arise from banding. The bands are not constricting, and the birds are unaware of them. Individual banded birds are often seen year after year at either end of their migration or at both; and sometimes during stopovers along the way:  they have all survived being banded, Also, if the scientists and conservationists were to take risks with the chicks in their care by using inappropriate methods, they would in fact be damaging or destroying the very creatures they have dedicated their skills to preserving.


Piping Plover Chick

WHAT’S SO SPECIAL ABOUT THIS SPECIES?

PIPL are not just rare, they are IUCN Red-listed as ‘near-threatened’. Last Autumn the IUCN estimate for adult birds was 8000 (now, in 2021, a greater number). The summer breeding grounds are located in quite specific areas of North America and Canada.

These vulnerable little shorebirds nest in scrapes on the beaches and forage on the shoreline. They face many dangers including predation (eg gulls, cats, foxes), human activities and disturbance (eg the inalienable right to use beaches for off-road fun), and habitat degradation (eg. development, encroachment, and pollution). This last is the greatest problem of the three, and it is of course the responsibility – or fault – of humans. Fortunately, the establishment of extensive coastal / shoreline wildlife refuges has provided managed habitat and careful protection in some areas.

Piping Plover Chick Holgate NJ (Michelle Stantial)

‘ABACO’

WHERE DOES BANDING COME INTO ALL THIS?

For the purposes of the ongoing scientific investigation and conservation research, the wildlife organisations in each area carry out programs to examine, measure, weigh and band birds on their ‘home’ beach. This process builds a database year on year against which the health of the birds and also the habitat can be measured. 

       

Banding enables individuals to be identified and observed in the breeding grounds; and crucially, where the birds overwinter (see below). Birds are given flags or bands or both in unique combinations. These may be put on one or both legs; mostly they will be on the upper leg(s), but sometimes the lower legs are also used; unique alphanumerics or coloured dots provide further means of ID. Some locations have a tradition of naming the chicks during banding. Thus one Abaco bird ‘Green Flag AH3’ became ‘Atari’ . Felicia Fancybottom is the most exotic name so far (she had a random posterior-feather sticking out when banded).

On Abaco, we sometimes give unnamed overwintering banded birds an ID to avoid confusion, for easy reference, or actually just for fun. For example Green Flag 70E became (obviously) ‘Joe’.

HOW THE SYSTEM WORKS IN PRACTICE

MANY HAPPY RETURNS FOR ‘SQUID’

January 2, 2018 a female bird called ‘SQUID’ was resighted on Abaco at Casuarina. Her bands were: upper left, blue on black; upper right, green on red (photo below). Checks of the band combination produced the following information:

  • originated from the Holgate unit of Edwin B. Forsythe NWR in NJ, banded there as a female
  • monitored and researched by Conserve Wildlife Foundation NJ
  • recorded at the same location the previous summer so had already completed Fall and Spring migration, returning to the same beach where she hatched and fledged.
  • named for the bander’s mom’s cat

Piping Plover, Casuarina Abaco Bahamas (Keith Kemp)

‘SQUID’

July 29 2018 SQUID was resighted for the second year at the same location on Casuarina flats, Abaco, the first banded bird of the season. She was also the last to leave, in mid-March – a stay of of around 8 months. During that time, APPW beach monitor Keith Kemp saw Squid on several occasions, all in the immediate area of Cherokee Sound (of which Casuarina is a part).

LATE MAY / EARLY JUNE 2019 Resighted for the third season at EBF, and nested with male (as it has turned out) called Sophia! Sexing tiny newly hatched chicks is not an exact science. Originally there were 4 eggs, but on June 2 only 3 chicks hatched – ‘nature’ had intervened with the 4th. They were named ABACO, CHEROKEE… and KEITH (a kindly nod both to monitor Keith Kemp and perhaps to me as well). The chicks were captured by Michelle Stantial of SUNY, in conjunction with CWFNJ, to be banded, weighed, and measured so they can be monitored and assessed for growth, beach activity, and protection purposes. In a couple of months these chicks will themselves feel the urge to fly south, and will continue the annual PIPL migration cycle.

 WHAT HAS THE RESEARCH REVEALED SO FAR – AND IS IT USEFUL?

SQUID is an excellent example of conservation, research, and science (both pro and citizen) in action. From his story we can conclude the following:

  • Squid has been on the same summer beach in NJ for 3 years running
  • She has also overwintered for 2 years running in the same location on Abaco
  • So she has flown 4 migrations of c1000 miles with extraordinary location accuracy
  • This is a prime example of ‘beach loyalty’, a vital ingredient for species conservation
  • At 2 oz, she is a doughty and determined survivor of all the dangers arising from such long journeys
  • The habitats at both ends of the migration are good and safe, without notable degradation 
  • The nesting success with A, C and K adds 3 more birds to the population, if they all fledge and survive
  • There is every chance that Squid will be seen on Abaco this Fall
  • There is some chance that at least one of the chicks will turn up on Abaco too; or in the Bahamas anyway

Piping Plover Chick, LBI (Northside Jim)

This story is one example of many similar ones that occur every season. One plover, Bahama Mama from Michigan, has spent the last 5 winters on the same Abaco shoreline. Overall, there is optimism that the conservation measures in place will prevent the decline and encourage the increase of the species. There’s a lot of dedication that goes into all this. I think it can be fairly said that the story of Squid and Sophia’s little family is a both reward for that dedication, and a sign of hope for the future.

NOT THE DITZY CHICKS!

PIPING PLOVERS: BAHAMAS RARE WINTER RESIDENTS


Piping Plover Abaco Bahamas (Bruce Hallett / Keith Salvesen)

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.

Piping Plovers, Winding Bay, Abaco, Bahamas (Lisa Davies)

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, Winding Bay, Abaco, Bahamas (Lisa Davies)

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.

Piping Plovers, Winding Bay, Abaco, Bahamas (Lisa Davies)

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’.

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.

STICKING TOGETHER: BIRDS OF A FEATHER

In times of trouble, of grief and of despair, humans have an instinct to rally round for the greater good. Right now, I am very conscious that on Abaco – and indeed Grand Bahama – there is little or no time or mental space for overmuch concern about the wildlife. I am safely distanced from the tragedies and dire misfortunes of the countless individuals, families and communities affected by Hurricane Dorian. In this post I simply offer some images of birds – all photographed on Abaco – that are bonded together as adults or adult and chick, as symbolic of the huge combined human efforts on Abaco to comfort, restore, and rebuild a shattered island.

It’s often a hard decision whether to include a short piece of video footage in a post. By short, I mean less than a minute. On the one hand, there is usually a good reason for inclusion, even if only aesthetic. On the other, it simply takes up more time for busy people who may prefer to flick through an article and enjoy some nice images along the way. Today, you can have the best of both worlds.

Sanderlings are definitively ‘peeps’, a group name that embraces the smallest and squeakiest sandpiper species. They are the wave chasers, the tiny birds that scuttle along the beach, into the retreating tide for a snack from the sand, and back to the beach again as the waves creep in. Their little legs and feet move in a blur, and many people immediately think of wind-up clockwork toys as they watch the birds in action.

One of the joys of being a sanderling is that rock pools fill and empty diurnally. At some time during daylight, there’s the certainty of a quick dip. I was lying on the beach when I took this short video, so that I didn’t spook the birds. I was equipped with a smallish camera (I drowned it the following day. By mistake I mean) but I kept my distance rather than try to get closer and spoil their joyful bathing.

I caught these little birds at a critical moment. You can tell that the tide is coming in fast. The peeps are becoming edgy, and weighing up the joys of immersion in a pool with the less enjoyable prospect of being washed out of the pool by the next wave. Within a minute or so, they had all flocked down the shoreline for a foraging session.

Next to the migratory PIPING PLOVERS that favour Abaco as their winter home, the wave chasers are my favourite shorebirds. My keenness on them killed my camera. I went out into the incoming waves to get shots back at the beach with the sun behind me. Great idea until I lost my balance with, as they say, hilarious consequences. Lesson learnt – never turn your back on waves.

ABACO’S RARE PIPING PLOVERS: CITIZEN SCIENTISTS WANTED FOR YEAR 5

  • BE A BEACH MONITOR IN THE CAUSE OF RESEARCH AND CONSERVATION OF A TINY RARE BIRD THAT CHOOSES ABACO FOR ITS WINTER HOME
  • NO EXPERIENCE NECESSARY; MINIMAL EQUIPMENT (pen, paper, binox & a ‘normal’ camera)
  • ABILITY TO COUNT TINY BIRDS IN (USUALLY) SMALL NUMBERS AN ADVANTAGE
  • SIMPLE AS TAKING A NATURE WALK ON YOUR FAVOURITE BEACH (but sorry, not with a dog)
  • COMMITMENT UP TO YOU – ONCE A WEEK, ONCE A MONTH, JUST THE ONCE
  • EVERY SIGHTING IS LOGGED – BANDED BIRDS ARE TRACKED BACK TO THEIR ORIGINS
  • EVERY BIRD IS A STAT THAT ADDS TO THE OVERALL PICTURE FOR RESEARCHERS
  • THE BIRDS MAY BE FOUND ON THE MAINLAND AND THE CAYS – EVEN THE MARLS
  • WE WORK IN PARTNERSHIP WITH THE SCIENTISTS  IN THE BREEDING GROUNDS
  • ABACO IS THE ONLY BAHAMAS ISLAND WITH AN ANNUAL WINTER-LONG WATCH

At the end of July – my guess is the 28th, on past form – the first piping plover of the winter season will be resighted on Abaco. It will weigh less than 2oz, and will have travelled at least 1000 miles (direct route). In practice it will be much further, because the journey will be broken by coastal stopovers en route.

My bet is that the first bird will touch down in the Cherokee Sound area. There’s a fair chance it will be called ‘Squid’  from New Jersey (for the 3rd year) or ‘Black Flag 2J’ from Prince Edward Island, Canada (for the 2nd year). At once, ABACO PIPING PLOVER WATCH will switch from summer indolence to red alert and piping hot… for the next 7 months. The last winter visitor will leave on ± March 15 2020 to return to its breeding grounds in the North (specific parts of northern US / Canada).

HOW ON EARTH CAN YOU PREDICT THIS?

Since the 2015-16 season, we have been monitoring Abaco’s beaches, shorelines, and flats (there are specific locations that are preferred by the birds) throughout the winter season. Each year adds to the data from previous years and as the annual information is analysed, the knowledge of the behaviours of this little plover significantly increases.

Over 4 years, distinctive patterns have emerged.

  1. Firstly, the plover numbers each season are fairly constant.
  2. Next, we have found that a number of birds return the following winter. Some are repeat returners – the current record is held by Bahama Mama from Lake Michigan, with 5 annual visits to the very same beach.
  3. Then, we have established that many of the banded birds are (a) resighted along the US coastline where they take a stopover during migration and (b) return to exactly the same beach where they were born.
  4. Often, we can find out when they hatched, fledged and left the beach – and even the person who did the banding.
  5. Finally, the number of banded birds – especially Canadian ones – is on the rise. This in part reflects an increase in summer chicks banding – but the fact is, we can show that they are turning up on Abaco, and returners usually turn up either on the same shoreline (or very close to it) as the previous year.

WOULD IT MATTER IF APPW DIDN’T EXIST?

In one sense no, because the birds would still undertake their Fall and Spring migrations, even if no one took any notice. But then, of course, no one would have any idea where the plovers might be for 6 – 8 months of the year. What the Watch can do, in conjunction with our partners in the breeding grounds, is to complete the annual migration circle and provide the specific details that help research and conservation of this rare little bird (world population around 8000). Furthermore, the Watch results provide continuing evidence that Abaco and its Cays provide a safe and suitable overwintering habitat for the birds.

These 3 little chicks are this summer’s hatchlings (in June) of parents Squid (see above) and ‘Sophia’. This is on the very same beach where Squid was born and banded in July 2017. Sometime this Fall, we hope that Squid will return for a 3rd year in Cherokee Sound. And we hope just as much that one or maybe all his chicks will arrive on Abaco too. We’ll certainly know if they do – we already know their band combinations! They each have an Abaco-related name – maybe that will encourage them too.

WHAT SORT OF PEOPLE CAN BE BEACH MONITORS?

Anyone at all. No experience is needed. You’ll be given all the info you need about the birds you’ll be looking for, and it may be possible to go out with a monitor to see what it’s like. Even a blank report is useful to have, to indicate where the plovers are not… And there’s no such thing as a mistake – the system allows for occasional miscounts, for example. Below is a summary of the last season, from which you can see the kind of data that is accumulated. 

You’ll see that there were 17 beach monitors of whom most were local Abaconians or regular second-homers. You probably know some or all of them! A few were visitors from US and UK. The 2 pro monitors were from our partners Conserve Wildlife Foundation NJ, and Audubon Caribbean. Keith Kemp is the wonderful and hard-working lead monitor and very regularly visits the hotspot shorelines. Other people made quite frequent reports, some about once a month, and several made fewer than 5. Each one added to the overall picture.

If you would like to become involved, even on the most casual basis, please do get in touch. Ditto if you’d like to know a bit more about it. If you decide not to go ahead – or once started, to stop – that’s all fine. It’s basically up to you whether you want to turn a beach walk into a bit of research (though as I mentioned above, it’s not a thing that can be done with a dog, for obvious reasons). Take a friend – or even a spouse. A single sighting might reveal a hitherto unknown location or a new banded bird – it happens every year. It’s Citizen Science in action!

TINY PIPING PLOVER CHICKS CAN SWIM! WHO KNEW?


TINY PIPING PLOVER CHICKS CAN SWIM! WHO KNEW?

Birds never cease to astonish and delight. Baby birds contain additional magic ingredients such as adorbium and cuteite. Ten days ago, a whole new level of spectator infatuation was effortlessly induced in the piping plover conservation team at Good Harbor Beach in Gloucester, Massachusetts.

The episode took a grand total of 35 seconds… For that is the time it took for three tiny piping plover chicks to get from one side of a small stretch of water to the other. By swimming! They had been spotted doing this the previous day, so the team were prepared. This was no one-off water-based miracle.

WATCH THIS CLIP AND BE UTTERLY ASTOUNDED AND ENCHANTED…

WHY DID THE PLOVER CHICKS CROSS THE WATER?

Alicia Pensarosa, amazed conservationist and photographer, later posted her video captioned “Mom and Dad plover fly to the other side first and then pipe at them to swim over. I think they do this to get to a better foraging area and to be less disturbed from beach crowds. They have been making their trek over in the morning and then come back in the afternoon (both on busy and quiet beach days)“.

WHY THE BIG SURPRISE ABOUT SWIMMING SHORE BIRDS?

Because as it turns out, very very few people have seen this behaviour before with the tiniest shorebirds. Alicia’s post on FB unsurprisingly has racked up loads of Likes, Loves, WOWs, OMGs and other enthusiastic emoticons. Plus plenty of shares. Plus a whole lot of comments and replies. In the interests of research I have examined these. One person once saw snowy plover chicks take a dip. Only two people had seen PIPL chicks do so. I’m pretty sure Michelle Stantial, pre-eminent PIPL scientist, has seen this phenomenon too. But overwhelmingly the responses can be summarised by the words ‘Who Knew?’ 

And now, assuming you watched the video (and if not, why not? and please scroll back and do so forthwith), you know it too. Here’s my current favourite chick to end with.
