HOW TO RECORD BIRDS EASILY ON ABACO (OR ANYWHERE ELSE…)

May 23, 2013 by Rolling Harbour

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…)

CUBAN PEWEE: NATURE’S LEAST SCARY TYRANT

May 8, 2013 by Rolling Harbour

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]

BLACK-FACED GRASSQUITS ON ABACO, BAHAMAS

BLACK-FACED GRASSQUITS ON ABACO, BAHAMAS

BFGs. Birds of the coppice, garden, feeder… and beach (see below). I posted some images last year HERE and now I have a few more, taken recently. Although their name is promising at first glance, the Title pun-value of these little birds is low, so I’ve left it… While the males are indeed black-faced, and often -chested too, the females are a drab brown. Until you look closely. Then you’ll see the olive shades, and the pretty yellow streaks on the wings.

ONE GOOD (ROYAL) TERN ON THE ABACO MARLS…

March 24, 2013 by Rolling Harbour

ONE GOOD (ROYAL) TERN ON THE ABACO MARLS…

…deserves another……and a few more besides…

We passed these fine Royal Terns during the boat ride ride out to the bonefishing grounds of the Abaco Marls. The single dead tree lay alone in a vast expanse of open water near the mangrove swamps, providing a perfect perch and vantage point for the birds. Their positioning on the tree suggested a distinct “pecking order”, which turned out to be literally true. The terns were unembarrassed by our presence, but at one stage they all took off and circled lazily round once before settling back on the tree. Those that tried to take a higher perch were aggressively treated by the original occupant. In the end, things settled down much as before. However, one disappointed claimant to promotion was dispossessed of the main trunk entirely. He ended up, uncomfortable and huffy, on a small stump facing the opposite way to the rest of the birds – perhaps from wounded dignity, or to make his feelings known through body language….

HERRING GULLS (Larus smithsonianus) CLOSE ENCOUNTERS OF A PREFERRED KIND

HERRING GULL Larus smithsonianus

The Herring Gull needs no introduction. So I won’t give it one. Instead, here are some close-ups of one that obligingly stayed still long enough, and at close enough range, to enable me to focus. The final two are possibly worth single- or double-clicking on to see the finer details. I prefer cooperative birds like this…

RED-TAILED HAWKS (Buteo jamaicensis) RAPTOR RAPTURE

February 25, 2013 by Rolling Harbour

RED-TAILED HAWKS: RAPTOR RAPTURE

Red-tailed hawks are one of the commonest and largest BUTEO species in North America, the Caribbean and further afield. There are fourteen widely-distributed subspecies. Their omni-habitat flexibility helps to maintain their prolific populations. They are equally at home in forests, grassland, open country, desert and even cities, at most altitudes.

This red-tail is preparing for flight. It had been sitting upright (see above), scanning for prey. Suddenly it hunched forwards, poised for take-off, the light of late afternoon sun catching its leg feathers. Moments later it raised its wings and was gone in an instant – the next photo an unusable blur of feathery speed.

6 RED-TAILED HAWK FACTS TO STARTLE YOUR AUNT WITH

1. The RTH displays SEXUAL DIMORPHISM in size – females average 25% heavier than males

2. Immature birds have yellowish irises. As the bird matures the iris darkens to a reddish-brown hue

3. They are easily trained to hunt: most hawks used for (tightly regulated) falconry in the US are Red-tails

4. They use tall trees, high rocks, utility poles or buildings as perch sites to scan large areas for prey

5. City hawks helpfully prey on rock pigeons and rats. ROSIE lives in Washington Sq NYC & has a web-cam

6. One urban RTH, known as PALE MALE, became famous as the first Red-tail in decades to successfully nest and raise young in Manhattan. He was immortalised by MARIE WINN in her book Red -Tails in Love: A Wildlife Drama in Central Park [RH Note: Good read]

6 RED-TAILED HAWK FACTS TO SURPRISE YOUR UNCLE WITH

1. The fierce, screaming cry of the RTH is often used as a generic raptor sound effect in TV shows & films

2. Eggs are incubated primarily by the female. The male helps out when the female leaves to hunt or stretch her wings. The male brings food to the female while she incubates

3. RTH young are known as eyasses (“EYE-ess-ez”), a falconry term for a raptor still in its downy stage

4. About 6 / 7 weeks after fledging RTH young begin to capture their own prey. They reach breeding maturity around 3 years of age

5. Red-tailed Hawks can live for more than 2o years – the oldest recorded was 29

6. RTH feathers are considered sacred to many American indigenous people. The feathers of the RTH are regulated by the “Eagle Feather Law” which governs possession of feathers and parts of migratory birds AFTERWORD These photos were all taken recently in New York, in Central Park (The Ramble, a birding hotspot) and in Prospect Park, Brooklyn. They are therefore a bit of a cheat in a website based mainly on Abaco. But I have never managed to photograph a RTH on the island, so these pics are illustrative of what I might have photographed had I (a) seen a RTH (b) had my wits about me (c) for long enough to find my camera (d) to photograph it before it flew away (e) and sufficiently well to be able to use the result [Header and due credit to Wiki]

SEABIRDS, SHOREBIRDS & WADERS: 30 WAYS TO DISTINGUISH THEM

January 31, 2013 by Rolling Harbour

Magnificent Frigatebird

SEABIRDS, SHOREBIRDS & WADERS: 30 WAYS TO DISTINGUISH THEM

I have recently been looking at hundreds of photos of birds, many with aquatic or semi-aquatic lives. These can be broadly categorised as seabirds, shorebirds or wading birds. But with some bird breeds, there can be doubt as to which category applies. There is the strict Linnaean ordering of course, but in practice there is a degree of informal category overlap and some variation in the various bird guides. This is especially so between shorebirds and the smaller, less exotic wading birds. Shorebirds may wade, and wading birds may be found on shores. Then I remembered a past blog post by the estimable BEACH CHAIR SCIENTIST that I thought deserved an outing here. I re-blogged the chart from BCS early last year. In the meantime site followers and site hits have surprisingly increased considerably, but I suspect only the dedicated make time to sift through any blog’s archives… Even if you have no problem distinguishing birds in the 3 categories, there are avian characteristics within each list that are interesting observations in themselves.

10 CHARACTERISTICS OF SEABIRDS

Whitetailed Tropicbird WikiPic White-tailed Tropicbird

(Examples include albatross, auk, booby, frigatebird, fulmar, gannet, penguin, petrel, puffin, shearwater, and tropicbirds)

1. Seabirds are pelagic, spending most of their lives far out at sea.
2. Seabirds move toward to coastal areas to breed or raise young for a minimal amount of time.
3. Seabirds are light on their undersides and dark on top (an adaptation known as countershading).
4. Seabirds have more feathers than other types of birds for more insulation and waterproofing.
5. Seabirds have flexible webbed feet to help gain traction as they take off for flight from the sea.
6. Some seabirds have unusually sharp claws used to help grasp fish under the water.
7. Some larger seabirds (e.g. albatross) have long, slim wings allowing them to soar for long distances without getting tired.
8. Some smaller seabirds have short wings for maneuvering at the surface of the water.
9. Seabirds have specialized glands to be able to drink the saltwater and excrete salts.
10. Some seabirds (e.g. gannets) have a head shape that is usually tapered for more efficiency in plunge diving.

10 CHARACTERISTICS OF SHOREBIRDS

Wilson’s Plover

(Examples include avocets, black skimmer, oystercatchers, plover, sandpiper, and stilt)

1. Shorebirds have long legs, pointed beaks, and long pointed wings.
2. Most shorebirds are migratory (Impressively some shorebirds fly non-stop for 3-4 days, equivalent to a human running continuous 4-minute miles for 60 hours).
3. Shorebirds wade close to the shore and poke their bills into the ground in search of food.
4. Shorebirds are small to medium size wading birds.
5. Shorebirds tend to frequent wetlands and marshes and are biological indicators of these environmentally sensitive lands.
6. Shore birds are of the order Charadriiformes.
7. Shorebirds are very well camouflaged for their environment and their appearance may vary from place to place as plumage (feather colors) are gained or lost during breeding.
8. Shorebirds typically range in size from 0.06 to 4.4 pounds.
9. Oystercatchers have a unique triangular bill that is a cross between a knife and a chisel.
10. The black skimmer is the only native bird in North America with its lower mandible larger than the upper mandible, which helps the bird gather fish as it skims the ocean surface.

10 CHARACTERISTICS OF WADING BIRDS

Great Egret

(Examples include crane, egret, flamingo, herons, ibis, rail, spoonbill, and stork)

1. Wading birds are found in freshwater or saltwater on every continent except Antarctica.
2. Wading birds have long, skinny legs and toes which help them keep their balance in wet areas where water currents may be present or muddy ground is unstable. Also, longer legs make it easier for them to search for food (forage) in deeper waters.
3. Wading birds have long bills with pointed or rounded tips (depending on what is more efficient for the types of food the bird consumes).
4. Wading birds have long, flexible necks that can change shape drastically in seconds, an adaptation for proficient hunting.
5. Herons have sophisticated and beautiful plumes during the breeding season, while smaller waders such as rails are much more camouflaged.
6. Wading birds may stand motionless for long periods of time waiting for prey to come within reach.
7. When moving, their steps may be slow and deliberate to not scare prey, and freeze postures are common when these birds feel threatened.
8. Adult wading birds are quiet as an essential tool for hunting. Wading birds may be vocal while nestling or while in flocks together.
9. Many wading birds form communal roosts and breeding rookeries, even mixing flocks of different species of wading birds or waterfowl.
10. Wading birds fully extend their legs to the rear when flying. The neck may be extended or not while in flight, depending on the species.

A JUVENILE BANANAQUIT ON ABACO – HOW CUTE CAN A SMALL BIRD BE?

June 19, 2012 by Rolling Harbour

BANANAQUITS Coereba flaveola

These small birds are a favourite of mine. They flicker around, cheeping cheerfully, yet are often quite hard to see in the coppice even if you think you are looking exactly where the sound is coming from.

Bananaquits are passerines, with an uncertain species designation. Over the years they have been officially reclassified three times. Some include them loosely with tanagers; others put them in their own family group; others argue that there are 3 distinct species. Basically, there is no universal consensus. There is some satisfaction, in a vastly over-classified world, in one small bird resisting man’s pigeon-holing (so to speak). It’s a tiny taxonomic enigma.

Among the islands of the West Indies there are several subspecies of bananaquit, with marked variations of appearance and size too tedious to relate. The best news is that “…the Bahamas Bananaquit with a whitish throat and upper chest may be a separate species…”.

The Bananaquit’s slender, curved bill is designed for taking nectar from flowers. It can pierce flowers from the side to reach the nectar, or use its bill to puncture fruit. It also eats small insects. The birds are tame, and love feeders, especially hummingbird feeders filled with sugar-water – hence their nickname “sugar bird”. They breed all year round. This is the characteristic chirrup of the Bahamas Bananaquit (credit: Xeno-Canto)

This small juvenile was happily feeding by itself near the Delphi Club, Abaco. Its mother then flew onto a nearby branch, and I’m afraid to say that the child indulged in a shameful charade of “Hungry! Feed Me! Now!”

ENDEMIC BAHAMA SWALLOW: FROM ‘THREATENED’ TO ‘ENDANGERED’ RED LISTING

March 13, 2012 by Rolling Harbour

THE BAHAMA SWALLOW: A SMALL ENDEMIC BIRD WITH BIG SURVIVAL PROBLEMS

The IUCN (International Union for Conservation of Nature) RED LIST status of the endemic Bahama Swallow Tachycineta cyaneoviridis has been upgraded from ‘Threatened’ to ‘Endangered’ because its small declining population faces a number of threats that are likely to worsen in the future. In particular, renewed logging activity and widespread property development could result in a further decline in breeding habitat.

The excellent photo above is the ‘Wikimedia poster bird’, but was in fact taken by prolific bird photographer Craig Nash in the main driveway of the Delphi Club, Abaco in 2010. He blogs as Peregrine’s Blog – see RECOMMENDED LINKS in right sidebar

This swallow species breeds only on 4 Bahamas islands: Grand Bahama, Abaco and Andros; and on New Providence, where a few birds are seen each breeding season, suggesting a ‘relict’ population there. The map below suggests that confirmed numbers are so few that New Providence sadly no longer counts as an ‘official’ breeding island.

The Bahama Swallow winters throughout the Bahamas and has been recorded as far as eastern Cuba, but in general the full wintering range is little known. It is a rare vagrant elsewhere during migration, including Florida. The preferred habitat is in the pine forests, where they nest in old woodpecker holes in Caribbean Pines using pine needles, Casuarina twigs, and grass to make the nest which they line with feathers. They typically lay 3 eggs. Incubation is 15 days and the fledging period is around 22 days.

Besides loss of habitat due to human intervention, other factors in population decline are thought to relate to hurricanes and forest fires. The Red List proposals for conservation of the Bahamas Swallow state: “Survey all suitable breeding habitat and assess the status of the species and its habitat; Gather empirical evidence to clarify population trends as a priority; Assess winter distribution and habitat requirements; Study the impacts of fire suppression on the species; Maintain natural nest-sites through a pine snag management programme, and potentially fire management; Assess and monitor the success of the nest box scheme; Protect remaining forest in the Bahamas and minimise the area lost to housing development and logging; Assess the impact of starling and house sparrows on the population and develop appropriate measures to reduce the threat”

The Bahama Swallow has joined other notable bahamian wildlife species in receiving the accolade of a stamp and a coin:

THE GOOD BIRD GUIDE 2010 – DELPHI CLUB, ABACO

April 8, 2011 by Rolling Harbour

This guide was compiled after our visit to Delphi in February 2010. It was originally intended purely for domestic consumption, as a light-hearted personal record and aide memoire. However, others suggested it might be useful for people wanting to make a quick identification of a bird they have seen around the Club or further afield. I was persuaded to put a copy on the desktop of the computer in the Club Library, and there’s now a hard copy around as well. I am currently revising it to include our 2011 visit. And now here it is in blog format. I.T. progress.
