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.

‘TUNA’ – a legendary regular from past years (Rhonda Pearce)Piping Plover on Abaco Bahamas (Rhonda Pearce)

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!

THE DITZY CHICKS & THE BEACH BYRDS: BANDS TO ADMIRE

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

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% are banded. All the birds are banded in their breeding grounds, usually as chicks (apart from a few ‘pink flags’ banded as adults on Long Beach, South Abaco). 

Piping Plover Chick Holgate NJ (Michelle Stantial)

‘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. 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.

‘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 ‘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 the 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 Sping migrartion, 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 me and to monitor Keith Kemp). 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!

BAHAMA MAMA: BIG NEWS ABOUT A TINY BIRD


Piping Plover Bahama Mama, Michigan / Abaco (Carol Cooper)

BAHAMA MAMA: BIG NEWS ABOUT A TINY BIRD

The bird in the header image is the presciently named Bahama Mama in Muskegon State Park, Michigan – so, one of the rare Great lakes piping plovers. She originally hatched and was banded as a chick in 2014 at Tawas MI, some distance away from Muskegon. When later named in 2015 by Muskegon monitor Carol Cooper, no one could possibly have known then where she would chose to overwinter. The Bahamas, as it turned out – the avian equivalent of nominative determinism.

Piping Plover Chick (MDF / Wiki)

This little bird is the perfect example to demonstrate the success of (a) an organised monitoring and recording system in the breeding grounds of these rare birds; (b) the use of easily identified coded banding and (c) the deployment of ‘citizen scientists’ to back up the professionals in the overwintering grounds such a Abaco.

A combination of the three factors leads over time to the compilation of a life story. Invariably there will be gaps, but let’s take a look at what we know about Bahama Mama, in her own dedicated timeline. Note two things: her beach fidelity; and the evidence of mate infidelity…

  • 2014 Born Muskegon State Park, MI
  • 2015 Nested with Little Guy and raised chicks. Winter location unknown
  • 2016 Returned to Muskegon and again successfully nested with a new male, Bear, from Sleeping Bear Dunes Park MI. (Little Guy went off with another female on the same beach…)
  • 2016 Resighted in October on Long Beach Abaco and stayed for several months
  • 2017 Back at Muskegon and raised chicks again with Little Guy
  • 2017 Again resighted  in October on Long Beach Abaco and overwintered
  • 2018 Back at Muskegon, initially back with Little Guy, eventually nested with Enforcer

The official record of the latest union – evidence of fickleness

This summer 4 chicks  were hatched. Sadly, one of them (Ringo, 2 pics below) was lost, presumed predated, leaving 3 to fledge.

These are rare and threatened birds, vulnerable at both ends of their migration for all the usual reasons. The studies undertaken at both ends of the migration have revealed astonishing beach loyalty in these little birds that travel up to 1500 miles (sometimes more) every Spring and every Fall to be somewhere safe to nest and breed; and then to overwinter. In Michigan, Carol Cooper is Bahama Mama’s mama, watching over her, recording the details, checking when she has left the beach, and anxiously watching each Spring for her arrival home.

On Abaco, these duties – pleasures, even – are undertaken by ABACO PIPING PLOVER WATCH and the team of citizen scientists who keep an eye on the beaches, count the birds, note the banded birds and photograph them for ID, and pass the info on to HQ (which happens to be me). The data from all sightings is collated and then the season’s stats are compiled and provided to the scientists involved. Here’s a summary of stats for last season:

POLITE REQUEST

If you live on Abaco or its cays anytime between August and March and might be interested in helping with piping plover research by becoming a monitor, please get in touch with me. It’s very simple and undemanding. A beach stroll from time to time – even as little as once a month – with a notebook, pencil, binoculars, a chocolate bar and (preferably for accurate ID of banded birds) a camera. Not a dog, though. Not on this walk anyway! Every report, even of a single bird, adds to the picture. Last season there was more than one ‘citizen scientist’ sighting of a plover where none had been seen before. 

PIPING PLOVERS ON GRAND BAHAMA (for a change…)


Piping Plover, Grand Bahama (Erika Gates)

PIPING PLOVERS ON GRAND BAHAMA (for a change…)

I used to go on a bit about piping plovers*, because they are so special. Rare. Endangered. Creatures rewarding observation, and deserving research and conservation. Most of all, they favour the Bahamas for their winter migration destination.  The islands – especially Abaco, Grand Bahama and Andros – provide a safe and unspoiled habitat for them in winter. The photographs shown here are piping plovers taken on Grand Bahama in early September by well-known birding guide Erika Gates, who has kindly given me use permission.

Piping Plover, Grand Bahama (Erika Gates)

These days, ABACO PIPING PLOVER WATCH diverts PIPL from these pages to a dedicated Facebook page. Now in its 3rd season, useful data is being collected for the research teams in the breeding grounds in North America by volunteer beach monitors**. Some are regular, some are occasional, some are one-off reporters: all contribute to the overall picture. In particular we are able to identify individual banded birds and track them back to their summer locations.

Piping Plover, Grand Bahama (Erika Gates)

WHAT USE IS THAT?

Almost every banded bird resighted this season is a returner to exactly the same beach as before. Some are here for their third or even fourth year. These tiny birds are therefore surviving a journey of between 1000 and 2000 miles each autumn and again each spring – and locating their favourite beaches with unerring accuracy. A few are resighted en route during their migration; often we get reports of their nesting and breeding news during the summer.  Their little lives can be pieced together.

Piping Plover, Grand Bahama (Erika Gates)

AND THE CONCLUSION TO BE DRAWN?

The summer breeding grounds generally have conservation programs that help to protect the nesting birds from danger and disturbance. Those are the most vulnerable weeks for the adults and their chicks. The arrival of the plovers each autumn on Grand Bahama, Abaco and elsewhere in the Bahamas demonstrates their ‘beach fidelity’. They are confident that the beaches offer a safe and secure winter habitat where they are left alone. And when the time comes in Spring, they will be ready to make the long journey north again for the breeding season.

A-PIPIN’ & A-PLOVIN’ ON ABACO: PIPL POWER

Last year someone kindly reported a lone piping plover sighting on ABACO PIPING PLOVER WATCH. I like to get a few details, so I asked what it was doing (meaning: sleeping / mooching / foraging / flying?). She replied – and I knew exactly what she meant – “Oh, a-pipin’ and a-plovin’ about on the beach”. A very evocative description of how these tiny scuttling birds pass their days!

Green Flag YLO, renamed Coco for short

The A P P Watch is now into its 4th month. The earliest reported arrival for the fall winter / winter season was as early as July 30. The first banded bird was reported on August 4, in a small group of 5. The leg bands (upper right Green Flag coded YLO; upper left Orange Band) at once confirmed the bird as an unnamed returner originating from Fire Island National Seashore NY – to the very same beach where it was sighted last December. That is known as ‘beach fidelity’, and is a most important piece of conservation data, because it is evidence that the beaches of Abaco provide a safe and unspoilt winter habitat for this vulnerable and threatened species. YLO was renamed Coco to reward his contribution to empirical conservation study.

We didn’t have to wait long for the next banded bird, one that had undertaken the longest journey we have yet come across, nearly 2000 miles (direct) from Big Barachois, Newfoundland. Black Flag 58 was soon traced to his origin and details of his adventurous life were uncovered – two summers on the same breeding beach, and a spring sighting on Long Island, NY.

The next find was a precious ‘Bahama Pink’ on Long Beach, known simply as… Pink Flag #50. She was banded on the same beach in 2014; resighted there in December 2015; and had returned for her third visit before the end of August 2016. The perfect example of ‘beach fidelity’.

There was a bit of a lull with banded bird sightings until October, when ‘Taco’ from the Holgate Unit, Edwin B. Forsythe NWR, NJ showed up. We had two other birds from the same location last season.

Soon after, a returner from last season arrived back on his same beach to join Taco. Jonesy was originally ‘Mrs Jones’, as in the song, until he was identified as a male and had to be renamed. He originated from the Ninigret NWR, R.I. He and Taco are still keeping company – they were seen together only yesterday.

Finally, a warm Abaco welcome please to the aptly named Bahama Mama, a rare Great Lakes bird from Muskegon State Park, MI, resighted in early November.  She was found on the same beach in December last year. Bahama Mama - Great Lakes Piping Plover on Abaco, Bahamas (Keith Kemp)15027859_392958301049767_8409742050501259206_n

So far this season, all the banded birds have been positively identified except one – a tantalising possible sighting of last year’s ‘Bird of the Season’ Tuna on ‘his’ beach.  From a distance shot the bands on one leg looked right… but all-in-all the image is simply not clear enough (and heavily pixellated with onscreen adjustments) to be certain. 

If it is indeed Tuna, then five of the banded birds so far are returners, in each case to the same beach as last year. The chart below is a draft (there’ll no doubt be some tidying up as the season progresses)
