BEAUTIFUL BIRDS OF ABACO, BAHAMAS (1): PRAIRIE WARBLER

The increasing flow of reports of recent bird sightings on Abaco seems to confirm the theory that in times of crisis and of recovery from disaster, people gain strength from the natural world that surrounds them. The bright flash of a parrots wings; the hoarse squawk of a West Indian Woodpecker; the unmistakable cheery call of the thick-billed vireo; the ‘peep’ of a shore-bird – all these can bring comfort in troubled times.

Right now, social media on Abaco, and radiating far beyond, is alive with more encouraging news after the storm, not least about the gradual re-establishment of normality as utilities and services are restored, movement becomes more possible, and plans for repairing the past and designing the future can begin to be made.

This post features photos of Prairie warblers taken on Abaco by Gerlinde Taurer, contributor to THE BIRDS OF ABACO. It is the start of a short series that will focus on a single species and feature gorgeous photos, all taken on Abaco. These bright little warblers are common winter residents and in normal times their Fall arrival would be well under way – along with some 30 other species of warbler that make Abaco – and the Bahamas generally – their winter home.

The rich diversity of the avian life of Abaco is truly astonishing: from residents to migratory species, from tiny to huge, from frequently encountered to very rare. Every bird (yes, even the reputedly ‘dull’ black-faced grassquits) has its own beauty and character. Even a small brown bird may have a lovely song. In non-storm circumstances, it would not be unusual for an amateur birder to encounter upwards of 40 species during half a day in the field – especially with binoculars. I hope that on a shattered island, appreciation of the lively and varied birdlife is already making a small yet positive contribution to the recovery.

‘THE BIRDS OF ABACO’: HURRICANE DORIAN RELIEF

ABACO, BAHAMAS has been all but destroyed by Hurricane Dorian. The horrendous scale of the disaster in human terms alone is only now becoming clear as the days pass and new tragedies are revealed. Many established relief funds – international, national and local – are being very generously supported for the benefit of those who have suffered so grievously. I am adding to the number through my specific link to Abaco and its wildlife.

GO FUND ME BIRDS

For obvious reasons, the GFM page (in edited form here) has a rather more formal , explicatory tone than I would usually use.

Sally and I were founder members of the Delphi Club, Abaco and retain strong connections with the island and the community. I run a conservation program for rare migratory plovers that overwinter on Abaco; and I am involved with BMMRO & its marine mammal research.

‘THE BIRDS OF ABACO’, of which I am the author, was published in 2014. The book was designed by Sally and published by Peter Mantle / The Delphi club. By the end of last year the edition had sold out, and all planned educational donations to schools, libraries and relevant organisations had been completed.

However, I have a couple of dozen books left in the UK. Through this fundraiser, I am offering a copy of the book in exchange for a donation of $150 (or the equivalent). The resulting fund (minus the cost of fulfilment from the UK) will be added to the funds achieved by the Delphi Club through their DORIAN RELIEF FUND .

A higher donation is of course encouraged; and please note, it is not compulsory to receive a bird book. Smaller donations are extremely welcome too, and for those of $50+ I will offer the donors a high-res PDF of a bird of their choice from a selection of several significant species found on Abaco; or a PDF of the complete bird species checklist for Abaco. That’s voluntary too.

The original price of this large photographic book was $145. It showcases the wonderful birds of Abaco with contributions from 30 photographers. Almost all are either residents of Abaco, or have strong connections with – and affection for – the island and its cays.

The books can be sent to Bahamas, USA, Canada and Europe. For any other destination, please contact me before you make a donation. Books will not be dispatched before October.

Please note that the Delphi Club does not have a stock of books and is not directly involved with this fundraiser. Please contact me with any inquiries, even though the Club details are shown on the pre-publication flyer below.

WAVE CHASERS: SANDERLING POOL TIME ON ABACO

WAVE CHASERS: SANDERLING POOL TIME ON ABACO

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.

Waves and incoming tide getting a little too close for comfort on the edge of the pool…

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.

‘A SADNESS OF SHEARWATERS’ ON ABACO: UNWELCOME NEWS

June 27, 2019 by Rolling Harbour

‘A SADNESS OF SHEARWATERS’ ON ABACO

If you are walking your favourite beach on Abaco right now, it’s quite possible you may see – or may already have seen – a very poorly seabird. Or one that is dead, I’m afraid. These are Audubon’s Shearwaters, also known as Dusky Petrels. They are the only permanent resident shearwater species on Abaco. Three others (Cory’s, Great and Sooty) are rare transients; and the last – the Manx – is a very rare off-course vagrant.

Each sad bird is part of a tragic and recurrent phenomenon, a so-called die-off event. As in previous years, a few of the birds that succumb may be Great Shearwaters mixed in with the Audubon’s. I first became aware of this problem in June 2015 and wrote two detailed posts about the situation. This bleak time lasted for about a week, and many reports came in from the mainland and the cays from Green Turtle Cay right down to Crossing Rocks, all duly mapped to get the overall picture.

There was thankfully no such problem in 2016, but in 2017 – also in June – there was another die-back event involving a large number of Audubon’s shearwaters (Puffinus lherminieri) appearing in the tideline and on beaches. Many were already dead. Some are still alive, but in a very poor state. The prospects for recovery for birds that were captured and cared for were not good.

Two years on, and the melancholy cycle is repeating itself. A few days ago, Melissa Maura, an expert in the care and recovery of creatures of all kinds, posted an alert and some sound advice:

A heads-up to all Island folk that it appears to be a summer when exhausted Shearwaters (pelagic seabirds) are washing up on our beaches in Eleuthera and Abaco. I have had two calls in 24 hours. Should you find one, understand that it will be in a severe state of exhaustion and stress and that excessive handling will kill it. Please put in a safe pen on a sandy surface, with shallow pan of fresh water and try locate either fresh fish (important) or squid from a bait shop. This may have to be administered by gently opening the beak and inserting one inch long piece of fish every couple of hours until stable. Ideally they need tube feeding, but very few folk can do this. Please contact me on private message if you find any…

WHY DOES THIS SHEARWATER DIE-OFF HAPPEN?

This is a periodic phenomenon that looks to be settling into a 2-year cycle in the Northern Bahamas (Eleuthera is also affected). The cause is probably a combination of factors, very likely stemming from prevailing mid-summer climate conditions and/or the effect of climate change. This can lead to a shortage of food far out in the ocean where the birds spend their days. This in turn leads to weakness and exhaustion as the birds try to find food. The birds may then land (or fall) in the sea, to be washed ashore in a very bad state, or dead. In 2017, well-known bird expert Woody Bracey noted a correlation between poor fishing conditions out at sea, and an unusual absence of the frigatebirds that are a sure sign of a healthy fish population.

ARE PLASTICS A CONTRIBUTORY FACTOR?

As we must all accept by now, most if not all these birds will unavoidably have ingested some of our discarded plastic. However, that in itself would not explain the simultaneous deaths of many birds of one type in a specific area, at exactly the same time of year, and for a few days only.

WHAT ELSE CAN BE DONE?

The dead birds will be quickly removed by the turkey vultures. If you do find one, you might want to bury it. The prognosis for sick birds is not that good. They may have been carried a long way from open sea and they will be exhausted and starved. Those that are strong enough may recover naturally; but most will sadly die, being too weak and emaciated to survive. There is no available facility able to deal with a large number of very poorly or dying birds.

The most practical advice I can give is:

(1) move the bird gently into the shade if in the sun

(2) provide clean water in a shallow dish

(3) offer finely chopped fish BUT no bread (it’s very bad for birds)

(4) if this seems to be working, then carry on until the bird is strong enough to fly (this may be quite a commitment)

(5) do not reproach yourself if a bird you try to help dies. Many will be in such bad shape by the time they are washed up that they are unlikely to survive whatever steps you take

(6) remember that this a part – a sad part – of the life-cycle of these birds, and (as with other species), a degree attrition is an inevitable aspect of natural life

I’d be interested to hear any other accounts of this year’s dieback, especially of any recovery stories. By all means do this as a comment, or email me, DM, or FB.

SANDERLINGS: A POOL PARTY ON ABACO

SANDERLINGS: A POOL PARTY ON ABACO

One of the pleasures of watching birds (as opposed to BIRDWATCHING, a more committed-sounding enterprise with its own Wiki entry, that may require equipment, books & mag subs…) is to spend some time observing them enjoying themselves. Perhaps you have a feeder, and like to watch the birds getting stuck into the seeds, carelessly flicking the husks around and throwing their ‘feeder shapes’ on the perches. Maybe you like to see the hummers, beaks deep into the little red plastic flowers on the rim of the sugar-water feeder, tiny bodies motionless and upright, wings a glistening blur of rapid movement in the sun.

It is 5.30 pm. The sun is sinking in the early evening sky. The tide is on the rise at the north end of the Delphi beach where the reef joins the land. There is a small spit of sand that will be covered quite soon, but meanwhile two dozen sanderlings mixed in with assorted ruddy turnstones are doing their idiot feeding thing, rushing around on their tiny legs, stabbing in the sand, and generally behaving like clockwork toys on speed. Meanwhile a handful have found the fun to be had in the swirling tide as it pours round the head of the reef onto the sand spit. Yes, it’s sandpiper bath-time!

Towards mid-tide on the rise, the water begins to creep round the rocks and encroach onto the sandbar. At high tide, it is well under water and fish are back in residence. Small sharks sometimes hang in the waves just behind their breaking point over the shallow sand. And so the tidal process repeats.

For the sanderlings, the best part of the day is when the tide is rising. At ± mid-tide is the time for the shore birds to bathe in the tidal pools that form – and as the water pours in around the end of the rocks, it froths like an overenthusiastic bubblebath. Right then is an excellent time to sit peacefully on the beach and watch the entertainment…

Substantial immersion is not out of the question…

These moments don’t last long. Soon the increasing force and height of the water spoils the fun, and the flock will suddenly take flight and move south a little way along the beach, away from the rocks. There’s the incoming tideline to play with – and more importantly, food to be uncovered with each incoming and retreating wave…

NORTHERN MOCKINGBIRDS: NEST + CHICKS = BUSY MAMA**

May 7, 2019 by Rolling Harbour

NORTHERN MOCKINGBIRDS: NEST + CHICKS = BUSY MAMA**

Anyone who has watched – and indeed heard – the behaviour of new chicks in a nest will recognise what is going on here. Four tiny Northern mockingbird chicks are passive and apparently dozy in the nest while they wait for one or other parent to fly back to fill their little faces.

As soon as they see or sense the imminent arrival of parent, the clamour begins. Me me me. Feed me first. “Fill-a-mi-beek”. Straining and craning forwards and upwards, with gaping yellow mouths. Pushing and shoving for optimum positioning. It’s all a bit frantic in that confined space.

Quite often, there’ll be a slightly smaller, less active chick at the back of the screeching pack… the best hope may be some leftovers or some food sprayed around in the mayhem. Then the parent bird flies off and the riot subsides. For a few minutes, anyway.

The 2 chicks at the back haven’t quite got the hang of the tactics yet…

The chick at the front – see him? – is out of the game..

As the photographer Melissa Maura wrote of this sequence: “A local avian staple seen in every Bahamian garden – the brilliantly musical Mockingbird. I followed this diligent Mamma for a few days in Abaco continually foraging for her 4 babies. Exhausting!”

* * Title / header: from the word ‘Mama’ onwards, there’s a notable absence of the role of `Papa’ in all this. He will have been the one to choose the territory and build the nest. His work complete, he can relax a bit in the knowledge that the chicks will fledge after only about a fortnight. Any Mama can cope with that, surely? Why interfere when it’s all going so well…

LOGGERHEAD KINGBIRD: LORD OF THE FLIES

May 3, 2019 by Rolling Harbour

LOGGERHEAD KINGBIRD: LORD OF THE FLIES

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

The loggerhead featured here became quite a good companion when I was staying in Sandy Point recently. Like other flycatchers – and indeed the cute little blue-gray gnatcatchers – loggerheads are curious and inquisitive.

Loggerheads seem to have two methods of observing humans and their mysteries. One is by perching on a branch or in a shrub, watching intently. They stay quite still… until suddenly launching into the air to intercept some passing insect with their hooked beaks (so-called ‘hawking’), before returning to their perch. And staring at you again. The other method is to follow you round, either flying slightly ahead as you progress; or fluttering in the coppice alongside you; or playing catch-up from behind.

Loggerhead and gray kingbirds are similar in size, and can be quite easy to confuse. Top seasonal tip: because the grays are summer visitors only, it’s a fairly safe bet that any kingbirds seen between, say, October and April will be the resident loggerheads.
