RECORDING BIRDS: A LAYMAN’S GUIDE

YOU WILL NEED: an iPh@ne or similar  smartphone with a voice memo facility; patience; minimal non-natural background noises (traffic, yelling people, barking dogs, heavy machinery); a steady-ish hand; one or more birds nearby

RECORDING

• Use the Voice Memo app on an iPh@ne (I presume most other smart phones have a similar app).
• Once you have it onscreen, turn the phone round 180 deg and the image will swivel round too. Now you can point the microphone at the sound and have the controls the right way up facing you.
• Turn the volume up to max before you record.
• Handle the phone carefully so it doesn’t record you touching it as well. It probably won’t pick up pressing ‘record’, but it may when you press ‘stop’. But you can trim the end of the saved file on the file very simply.
• The recording saves in m4p format, and you can email it to your computer direct from the app (or to anywhere or anyone else).
• Drag / save the file onto your desktop from the email. When you open it, it will (a) play and (b) appear in your iTunes library (or whatever music storage system you use).

CONVERTING RECORDINGS TO MP3

• Having opened the recording, to convert the file to an mp3 (generally the preferred version for uploading elsewhere) in iTunes, go to Songs in your iTunes library and search for Memo. There it is!
• You can rename it at this stage if you wish.
• Then go to File on the top bar, and in the drop-down menu, near the bottom, go to Create new version. It will offer you mp3.
• Click mp3 and a second recording file will appear in your library. That’s your mp3.
• Drag it onto your desktop and do what you want with it.

Apologies if this is all blindingly obvious and written in the elementary computer language ‘eggy-peggy’. It took me a while to get it sorted out, and I hope the details above will help the lo-tek computer user to record birds and use the results painlessly.

FIELD NOTES

• I recommend recording for about 20 – 30 seconds max. The iPh@ne  allows easy trimming at the start and end of the saved file, but there’s no easy way to edit the middle to take out the barking dog.
• Several short recordings of each bird will give a better choice of results than one or 2 long recordings.
• The iPh@ne mic is surprisingly sensitive. It will pick up all nearby sounds – someone whispering at you “is it recording yet?”, for example. So ideally this is best done in the pine forest or coppice, away from the Highway. And maybe the loud whisperer.
• Wind can be a problem. Not just for humans. The mic will pick up gusts of wind, or wind blowing across it if you change the direction you are pointing the phone as you record. So this is best done on a calm day.

Here are two practice recordings I made in March. The first is the female red-winged blackbird above (and header) at Casuarina beach. The distinctive call is rather like a rusty hinge on a swinging gate, often heard far out in the mangrove swamps of the Marls. You’ll hear background noises from collared doves and also the sea lapping on the shore.

The second is thick-billed vireo in the coppice at Delphi. You’ll hear an answering vireo – and also some wind noise. I find these little birds frustratingly hard to see – they always seem to be lurking further back in the bushes than I think. I’ve never managed to take a good photo of one, so I’ll upload an illustrative poor one to be going on with. I am back on Abaco in a week, and a better TBV photo is on my avian hit list.

Finally, you’ll find a longer recording I made of Abaco parrots squabbling noisily at Bahama Palm Shores near the end of a recent post HERE. I made an mp3 using the method described above, and uploaded it to the excellent Xeno-Canto bird sounds website, which is well worth exploring. You can find my recordings of the parrots and the birds in this post, plus sonograms, on my XC page, such as it is, HERE 

But if you just want to hear the parrots, here they are. Like schoolkids, only louder.

Why do I do that annoying ‘iPh@ne’ thing? It’s a statistical fact that I have just made up that 373,597 people a minute world-wide g@@gle the correct word. Imagine the meta-crawlers and spam-splurgers that lock onto that word. I don’t want to cyber-meet them. I also use the form Am@z@n but for different reasons relating to their ingenious tax arrangements (alleged, obviously). Thus  with G@@gle as well (again, merely alleged – as Dusty Springfield memorable sang, “Nothing is proved…)

GREEN PREEN: CUBAN EMERALD HUMMINGBIRD, ABACO 

This tiny bird was in the Abaco coppice, well off the beaten track. Nearly two miles down a notably unbeaten track, in fact, that later was to lead to a puncture-and-@$%^&*-I-forgot-my-cellphone drama. Trauma, even. The hummer knew perfectly well that I had crept up behind it, but it had presumably seen few bipeds. It would not have known of their urge to bulldoze wild habitat and turn it into massive unsold developments, as has happened a short way up the coast… So it just carried on with what a bird has to do to keep itself looking presentable, while I, feeling rather rude and intrusive, took some quick pictures before leaving it in peace. Rather than sell these intimate studies to Hello!, OK!, Chirpy! or Tweet!, I am displaying them free for your enjoyment.

In addition to the Cuban Emerald, the Bahamas has its own endemic hummingbird, the Bahama Woodstar. In the faltering early days of this blog, I posted about them both at BAHAMA WOODSTARS & CUBAN EMERALDS: THE HUMMINGBIRDS OF ABACO At that time, I was not really a ‘birder’ at all, and had only a very basic camera, so my own pictures were… very basic. But you may be interested in some of the info in the post about these two species, so I mention it in passing.

ABACO WHALES & DOLPHINS: BMMRO SIGHTINGS & NEWSLETTER

I haven’t posted Abaco whale, dolphin & manatee news for a while. Time for a catch-up. Georgie the young manatee that left her mother Rita and came to Abaco from the Berry Is. alone, is no longer here. She survived a very long journey, and investigated various coastal areas of Abaco – all the while being tracked. In the end she settled down in the Cherokee area. There were anxious times during Hurricane Sandy when she went missing (having by now shed her tracking device) but she eventually reappeared at Cherokee having found a safe haven from the storm. Sadly, however, her condition deteriorated and in the New Year she was relocated to Atlantis Dolphin Cay Marine Mammal Rescue Center. Some weeks ago a healthy Georgie was moved to a sea-pen to acclimatise her for release back into the wild.

The Bahamas Marines Mammal Research Organisation (BMMRO) is based at Sandy Point, Abaco. A number of research projects are underway, and recently these have involved work on Andros. The team are now back, and encountering Abaco’s own dolphins and whales. The main photos on the page have all been taken in the last week or so. [The header is by Norwegian artist Roll Inge Haaver]

BLOOMING MARVELLOUS: FLOWERS OF ABACO

The flowers and plants below were mostly photographed in the grounds of The Delphi Club, Abaco or nearby. I expect most or many are already securely on the SD chips or hard drives of every visitor to an agreeably floral place like the Bahamas. Who can resist a pretty flower? I have confessed in earlier plant-based posts (links below) to a certain lack of aptitude around flowers. They just… are. Let’s see how this pans out – corrections and (for the last two) IDs welcome.

I’m beginning to struggle now. The next two plants are probably completely obvious, but I am losing my floral grip. Suggestions welcome via the comment box or email (Bridget on Tilloo, that means you…)

STOP PRESS ID within 24 hours, thanks to Nick Kenworthy who says via the comment box that this bright pink one “is loosely referred to as the Orchid tree (or Hong Kong Orchid Tree) as the blooms are very like an orchid but it comes on a tree rather than a plant”. I’ve checked my cheat books, where it is named Bauhinia pupurea, aka Orchid Tree, Butterfly Tree or (from the leaf shape) Bull Hoof Tree. The tree originates from India and Southeast Asia. Nick has undoubtedly nailed it, for which many thanks. One more to go…

ORCHID TREE Bauhinia pupurea

STOP PRESS 2 Nick has solved the second ID as well. His interesting information about this striking waxy plant can be seen in detail in the comments below. The answer, in a word, is ‘Jatropha’, of which there are a great many varieties – and quite a number of informal names, most of which (‘Firecracker’; ‘Star of Bethlehem’) are confusingly assigned to other plant species as well. It doesn’t feature in either of my Caribbean plant /tree reference books, so my amateur eyes didn’t actually let me down this time… This plant (there was were two of three) was in a small park area by the beach at Treasure Cay. I haven’t seen it elsewhere on Abaco.

LEAST, BUT NOT LAST: THE SMALLEST SANDPIPER

The LEAST SANDPIPER (Calidris minutilla) is the smallest shorebird, the definitive “peep”. An adult is only about 6″ long. They are to be found in pairs or groups, busily foraging in the sand and seaweed. Often they will mix in with other shorebirds. These birds nest in scrapes close to the water, with both parents involved in incubating the eggs. The female will usually leave the nest before the young birds fledge - perhaps (bizarrely?) sometimes even before the eggs hatch. Deal with it, male Least Sandpipers. Fortunately the hatchlings can feed themselves very soon, and are able to fly within two weeks of birth.

The “peep” call will no doubt be instantly familiar, although how to differentiate between the various types of sandpiper may be more of a problem… Here’s a short recording via Xeno-Canto (credit: Mike Nelson) 

They may burrow deep into the seaweed near the shoreline to reach an especially good feeding patch

CUBAN PEWEE: NATURE’S LEAST SCARY TYRANT

The CUBAN PEWEE Contopus caribaeus bahamensis, also known as the Crescent-eyed Pewee (see photos for details), is a tyrant. At 6″ long , the smallest tyrant you are likely to encounter in the Bahamas, but undoubtedly a member of the family Tyrranidae. These are the flycatchers, and include the larger LA SAGRA’S FLYCATCHER and the still larger Loggerhead and Gray Kingbirds. The Cuban Pewee is permanently resident on Abaco, and can be found in both pine woods and coppice. When returning to its perch after a flycatching sortie, this bird gives a characteristic flick of the tail.

The little bird below was in the edge of the coppice bordering the long sandy beach at Casuarina. Bruce Hallett, in his essential book  ’Birds of the West Indies…’ notes that Cuban Pewees are ‘usually approachable’, so I decided to test this out. I was about 20 feet from the bird when I first saw it. By sliding one foot forward in the sand and pausing before moving the other foot, I got to within 5 feet of the bird, while it watched my approach with apparent indifference. Unlike some creatures, it did not seem discomfited by eye-contact. It responded when I made a faint clicking sound by rather sweetly putting its head on one side.  Then it began to fidget slightly – possibly feeling camera-shy. So I shuffled slowly back so as not to disturb it in its own territory.

The close-ups at the end clearly show the tiny hooked tip at the end of the upper beak – I imagine this somehow relates to the business of catching flies. Like other flycatchers, the Cuban Pewee has very distinctive whiskers around the base of the beak – again I presume this assists with feeding in some way, perhaps helping to sense the approach of an insect. Any expert views welcome via the comment box.

It’s occasionally tempting to anthropomorphise such close encounters in terms of imputed human / creature empathy. Much best to resist that. But as I withdrew, leaving this little  bird undisturbed on its branch, I did experience a strange feeling of… [I must interrupt myself here. I'm a lawyer, so that's quite enough of that sort of nonsense]

ABACO’S UNIQUE PARROTS IN PICTURES, VIDEO & SOUND

Abaco parrots. The only ground-nesting parrot species in the Bahamas. In the world, in fact. I’ve posted quite often about them – indeed they have their own page HERE – because, frankly, they are special and their story is one of encouraging success for intensive research and conservation programs. In 1492, Christopher Columbus was amazed by the vast number of parrots he saw in the Bahamas (not that the islands were called that then). In his journal he noted: “flocks of parrots darken the sun…”  Not many years ago, parrot numbers on Abaco had dwindled to fewer than 1000 – below the critical point for sustaining a viable population. Extinction of the Abaco parrot loomed, accelerated by increasing habitat change, predation, and (*euphemistically*) ‘human intervention’.  Thanks to the campaign of conservation, habitat preservation, anti-predation measures and vigilance, numbers have been restored to a sustainable level, perhaps as many as 4000. They are now a fairly common sight – and sound – in South Abaco. But not everyone who looks for them finds them, or even hears them. Especially not if they take pot luck in the vast areas of pine forest in the National Park, where they breed…

I’ve covered much of this ground before, but there is a slightly wider audience these days, so a few newcomers may be interested to learn about these lovely birds. The best thing is to have a look. All photos were taken by me during two early evenings in March.

The parrots are extremely agile, and have very strong feet and claws that enable them to move around in the tree-tops – or to hang upside down if they choose to. The next photo is a close-up a foot; below that is short video showing a parrot manoeuvring itself in a tree. You’ll also see how the birds use their beaks as an extra limb, so to speak. The uninspiring title shown is only because I forgot to label it ‘Abaco Parrot’ in the first place, and can’t find how to edit it…

In this image you can clearly see how their ‘opposable’ claws wrap round a branch

If you suspect that this one has had some ‘work’ done, you’d be right. I normally leave my photos largely alone, apart from cropping and maybe basic light balancing where needed. Sometimes an image is nearly there, but needs a bit of extra cosmetic business – but one can usually tell. The left wing? Hmmmmm (users of ‘noise reduction’ will know what I am talking about!).

The flocks of parrots are incredibly noisy. Sometimes they split into two or three groups, close together, and seem to compete in raucousness. Around 5.00 pm seemed to be the noisiest time. I took recordings of the racket, using the voice memo app on an iPh*ne, simply holding the phone with the speaker / mike end towards the parrots. Some come out pretty well – good enough to post on the excellent XENO-CANTO bird sound site. Here is a recording, with the first few seconds transcribed into a sonogram. I made a ring tone from this recording for Caroline Stahala, the scientist who, with her team, looks after the birds. She’s been too polite to say whether she uses it or (more likely) not!

I find the parrots very hard to nail in flight (see above), possibly because of a shutter-speed issue (mine, not the camera’s). I nearly junked the picture below, but I liked the clash of the parrot colours with the purple bougainvillea, so I spared it.

BURNING SENSATIONS: FOREST FIRES ON ABACO 

My last post was about SAWMILL SINK – not the famous Blue Hole itself, but the detritus of past logging activity in that part of the Abaco pine forests revealed by last month’s forest fires. I mentioned that this destructive burning of the shrubby understorey is (allegedly) the work of  hunters making it easier for their dogs to pursue the hog denizens of the forest. The evidence suggests that nature alone could not cause so many separate seats of fire to appear in a matter of days over such a wide area – and in springtime at that.

This year, the fires came uncomfortably close to several small communities and outlying residences – and to the Delphi Club itself. Many people spent nights hosing down undergrowth and building on the edge of settlements, with neighbours all joining in. Electricity poles are vulnerable, with obvious consequences for the supply should they burn through at the bottom, as often happens. One pole a short way south of Delphi on the highway has the burnt remains of 3 utility posts beside the current (ha!) one. At Delphi itself, the vegetation from around all the poles along the mile of drive had to be cleared.

This iPhone photo was taken from the Delphi balcony. The fire is in fact on the far side of the highway, with the pall of smoke – and therefore the fire’s direction – heading south. The question is, when and where will it jump the highway, and what will be the wind direction then…

This picture shows the extraordinary effect of the smoke-laden atmosphere on the sunset. The header picture is another example. The fire is now into the pine woods between the Club and the highway, and the theory that the damp coppice nearer the Club will act as a barrier to prevent its spread is about to be put to the test overnight…

It soon became clear that the fires were not going to be discouraged by the coppice.  Sandy is always eager to find volunteers to go out in a truck to feel the heat, so to speak. He is apt to dismiss concerns that one is sitting on top of a large tank of inflammable liquid by pointing out that diesel is less combustible than petrol. This is invariably comforting to all occupants of the vehicle. So with the fire burning bright, and with tree-tops suddenly bursting into flame like torches, off we go…

In the morning, a smokey mist lies over the trees and the bay to the north

An uncomfortably short distance along the guest drive, it is clear that the coppice has burnt quite easily, though not devastatingly. In fact there are still flames to be seen…

Later, out on the Marls, a plume of smoke is visible, with several more in either direction

Despite the widespread damage caused by the fires, the capacity for regeneration is amazing. New growth is visible very quickly, and within the year the burnt-out areas are mostly back to normal. I’ll end on that optimistic note, and with another dramatic sunset above the haze of smoke over the tree canopy.

SAWMILL SINK, ABACO: INDUSTRIAL ARCHAEOLOGY IN A POST-APOCALYPTIC LANDSCAPE

1. BLUE HOLES

The Blue Holes of Abaco are geological wonders about which much has been written – much of it in the NATIONAL GEOGRAPHIC MAGAZINE. Sawmill Sink is one of the best-known inland ones; and there are other holes in the shallow seas on both sides of the island. They are deep chasms in the limestone rock, many leading to extensive and complex cave systems under the island. Divers exploring Sawmill Sink have found many prehistoric fossils, including those of an extinct giant tortoise, and land crocodiles. Most conveniently, this fascinating blue hole is close to Delphi, hidden deep in the pine forest and accessible only by historic logging tracks.

AERIAL VIEW OF SAWMILL SINK DEEP IN THE PINE FOREST

This article is not about Blues Holes in general, nor Sawmill Sink  specifically. I have such a post planned, but for the moment I’ll put some relevant links at the end of this one. Feel free to scroll straight there if the cumbersome heading has already put you off… but in an effort to hold your interest, here’s an image of the Sink to give you an idea of what it looks like. There are wooden steps down and a platform to enable you to swim in it (there are no crocodiles these days. So they say…).

SAWMILL SINK, ABACO

2. A LOGGING HISTORY

South Abaco – defined loosely as the area south of Marsh Harbour – is dominated by pine forest. There are a few settlements and individual residences, all by the coast. The forested swathes are criss-crossed by an extensive system of logging tracks, many now all but impassable. They are reminders of Abaco’s historic importance as a source of wood deriving from the ubiquitous tall, slim pines. One use to which they were put was as mine pit props in the collieries of Wales.

Last June when we went to Sawmill Sink, we saw a rusty rail sticking up from the undergrowth. We were with Ricky Johnson, the man who could invariably answer any question about Abaco; he explained that there had at one time been a light railway through the forest to carry the felled timber to the highway, where it was transported to the coast for loading onto ships.

Last month we returned to Sawmill Sink. The south part of the island was enduring the annual outbreak of forest fires, most (if not all) believed to be set by hunters wanting to clear to undergrowth to make hog-hunting easier. While the occasional natural fire is actually good for the forest (cf burning moorland), the set fires do great damage over a vast area. On some days there were 6 or more separate seats of fire appearing in one day – highly unlikely to be the work of nature. Thick palls of smoke drifted across the island, and out to sea. Even far out on the Marls, the fires were visible, with the smell of burning carried on the wind. This year, the fires came uncomfortably close to some of the settlements. Night-long community action was needed in some places to protect property. At Delphi, the fires came within 300 feet or so before finally fizzling out in the coppice… Two years ago, they  came nearly as close. For a post-fire wander round the Delphi drive circuit click FOREST FIRES (it was one of the first, tentative posts on this blog – and boy, does it show… it needs a rethink)

DELPHI GUEST DRIVE: A WARM WELCOME

The photos that follow show the track to Sawmill Sink immediately after a fire had swept through the area. Trees were still smouldering and in places the ground was still hot to the touch. Along the way the evidence of the former usage had been laid bare. Some images show the paved path that leads from the logging track to the Sink. I have no idea if these are the first images of so many visible remains of the logging trade, revealed by the burnt-off undergrowth. I haven’t tracked down any others at all so far. I write as a non-resident of the island, so if anyone can add any information, please do so via the COMMENT box. 

Finally, we found this rock close to the Sink. Are those plant fossils? Bearing in mind that sea probably covered this area entirely (the highest point on Abaco is a mere 134 feet ASL), might these be anemones or sponge fossils of some sort? Comments from fossilologists welcome.

STOP PRESS thanks to FOSSIL LADY (aka Kathi) for the following: “Those don’t look like plant fossils to me, they remind me of stromatolites, a sponge like creature that first dominated the earth billions of years ago. Some varieties still survive today. It would be worth it to have a geologist have a look see. ps the sinkhole is awesome!”
