THICK-BILLED VIREO ‘ON VOCALS’: A CHIRPY JUVENILE ON ABACO

I’m not sure that TBVs would rank as anyone’s all-time favourite bird. Probably not in the top 10. Or 20. But we have a particular affection for them. When we first arrive at Delphi, that cheerful call is invariably the first birdsong we hear. And when we leave, it’s often the last. These small birds inhabit the coppice on either side of the drive, and are often found right by the the Lodge.

The strange thing about them is that despite their ubiquity and their uninhibited advertising of their presence, they are surprisingly hard to see, let alone get a clear photograph of. A singing TBV often seems to be at least 2 rows of bush further back than it sounds, concealed by intervening branches, leaves, and twigs.

Maybe growing juveniles are less cautious. This little guy is right out in the open, and singing away happily. He’s still cutely fluffy, but his plumage already starting to turn yellow. He has the diagnostic yellow marking in front of and around the eyes. However at the base of his characteristically plump beak there’s still a hint of baby bird mouth.

Here’s a recording of an adult TBV I took from the Delphi drive (you may need to turn up the volume a bit). And no, I couldn’t actually see the bird, though I knew exactly where it was from the slight movements of foliage. All-in-all, the TBV is a most engaging little bird and well-deserving of affection if not perhaps a high placing in the Avian Popularity Charts…

BAHAMA MOCKINGBIRDS ON ABACO: GOOD IMPRESSIONS


Bahama Mockingbird, Abaco - Tom Sheley

BAHAMA MOCKINGBIRDS ON ABACO: GOOD IMPRESSIONS

The Bahama Mockingbird Mimus gundlachii is similar to its slightly smaller cousin, the widespread Northern Mockingbird Mimus polyglottis. The range of Bahama Mockingbirds is not restricted to the Bahamas themselves, and includes areas of  Cuba, Jamaica and TCI, so despite the name they are not an endemic species to the Bahamas.  They are also occasional vagrants to the United States, especially – for reasons of proximity – southeastern Florida.

Bahama Mockingbird, Abaco - Peter Mantle

The Bahama Mockingbird is browner than the greyish Northern Mockingbird, and has distinctive streaking and spotting to its breast and undercarriage. This may extend to what you might describe as the bird’s ‘trouser legs’, though I’m sure there’s a more technically correct term.

Bahama Mockingbird, Abaco - Charlie Skinner

Both mockingbird species are found on Abaco. The NMs are ubiquitous in towns, settlements, gardens, coppice and pine forest, whereas BMs are shyer and tend to be found in the pine forest and well away from humans and their operations. When we were putting together The Birds of Abaco, I went on a birding trip with Abaco birding legend Woody Bracey and Ohio bird photographer Tom Sheley. We took a truck into the pine forest down a logging track south of Delphi, and they were quick to locate a bird, not least because one was sitting prettily on a branch singing lustily and unmistakably. It was well within range of Tom’s massive lens; more of a struggle for my modest camera (below). Caught the cobwebs, though…

Bahama Mockingbird, Abaco - Keith Salvesen

I was astounded by the beauty and variety of the song. It consisted of very varied notes and phrases, each repeated 3 or 4 times before moving on to the next sounds in the repertoire. Here is a short 18 second example I recorded, using my unpatented iPhone method, for which see HERE.

Bahama Mockingbird, Abaco - Alex Hughes

For those with interest in birdsong, here is a longer 1:13 minute song from the same bird, with largely different sounds from the first recording made minutes earlier. There’s even a decent stab at imitation of a 1960s Trimphone™. Had we not had to move on to Sandy Point for an appointment with some cattle egrets and American kestrels, I could have stayed listening for far longer.

Bahama Mockingbird, Abaco - Tom Sheley

THE ‘SUBSPECIES’ THAT WASN’T…

More recently, on a trip in backcountry to find Kirtland’s warblers – we saw 4 – the slow-moving truck jolted to halt in the middle of nowhere. This was because a Bahama Mockingbird was right by the track. I fired off some quick shots out of the window into a rather difficult light, to find that we appeared to have found a new subspecies, the scarlet-faced mockingbird.

Bahama Mockingbird, Abaco - Keith Salvesen

The reason was clear, however. The bird had been pigging out on some red berries, and had managed to collect plenty of the juice round the base of its beak. Bahama Mockingbird, Abaco - Keith Salvesen

SO WHAT DOES A NORTHERN MOCKINGBIRD LOOK LIKE, THEN?

I photographed the Northern Mockingbird below in a garden at Casuarina. The species is far tamer than its cousin, and seen side-by-side they are clearly very different. The range maps show the stark contrast between the very limited range of the Bahama Mockingbird and the vast distribution of the Northern Mockingbird.

MAGNIFICENT FLYING MACHINES: FRIGATEBIRDS

MAGNIFICENT FLYING MACHINES: FRIGATEBIRDS

It’s almost exactly one year since I last posted about the Magnificent Frigatebird aka Man-o-War Bird (Fregata magnificens). You can read about their courtship displays, gular pouches, nesting habits, names, uses to mankind (if any), and 10 magnificent facts about them HERE. I’ve included some truncated facts below.

Now is a good time to revisit these wonderful sky pirates, for 2 reasons. The first is that photographer Michael Vaughn has produced some outstanding images of the species. The second is that I have just watched a characteristically superb BBC David Attenborough prog showing frigatebirds robbing tropicbirds of fish – despite them being lodged in the tropicbirds’ throats (for safekeeping…). Here’s the link to the sequence.

10 MAGNIFICENT FACTS ABOUT FRIGATEBIRDS

  • The largest of several frigatebird species around the world
  • Found in tropical and subtropical waters
  • Females have white fronts – easily distinguishable from males in flight
  • Adult wingspan is 7+ feet = largest wing-area / bodyweight ratio of any bird
  • Can remain in flight and far out to sea for many days
  • KLEPTOPARASITES – will rob other seabirds of their food
  • Diet: mainly fish & squid from the water’s surface; seabird chicks
  • Nest in colonies, producing a single egg every other season
  • Don’t land on water, as they can’t float; and feeble at walking on land
  • One of the earliest depictions of a frigatebird is by Eleazar Albin in 1737. He was a naturalist contemporary of MARK CATESBY & pre-dated AUDUBON

SANDERLINGS: BATH TIME FUN AT DELPHI, ABACO

SANDERLINGS: BATH TIME FUN AT DELPHI, 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. 

Sanderling Bath Time, Delphi Beach Abaco Bahamas - Keith Salvesen

Well, join me at Sanderling Bath Time on the Delphi Beach. We are the north end, where the exposed rocks of the reef curve round towards the beach. At low tide, there’s a sandbar bridge from beach to rocks. It is a perfect feeding area for shore birds. Sanderlings, ruddy turnstones, least sandpipers, Wilson’s plovers and the prized piping plovers forage happily together here.

Sanderling Bath Time, Delphi Beach Abaco Bahamas - Keith Salvesen

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. But ± mid-tide is the time for the shore birds to bathe in the tidal pools that form – and become frothier as the water pours in. And it’s an excellent time to sit peacefully on the beach and watch the entertainment…

Substantial immersion is not out of the question…Sanderling Bath Time, Delphi Beach Abaco Bahamas - Keith SalvesenSanderling Bath Time, Delphi Beach Abaco Bahamas - Keith SalvesenSanderling Bath Time, Delphi Beach Abaco Bahamas - Keith Salvesen

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…Sanderling Bath Time, Delphi Beach Abaco Bahamas - Keith Salvesen

“THE DELPHI CLUB GUIDE TO THE BIRDS OF ABACO” (2016)


Delphi Club Guide to the Birds of Abaco (Jacket)

“THE DELPHI CLUB GUIDE TO THE BIRDS OF ABACO”

In a box in the corner over there – no, there – are my last 6 copies of ‘The Birds of Abaco’. Peter Mantle probably has a few over here in the UK too. And there are definitely some remaining at Delphi HQ in a cupboard  just a few lurches away from the surprisingly popular ‘honesty bar’. But there aren’t a great many left now, so forgive me for drawing attention to the fact that the Season of Goodwill is upon us. And… ahem… there are only 24 more ‘sleeps’ until Christmas.

“The Delphi Club Guide to THE BIRDS OF ABACO” was published in March 2014. To say “I wrote it” would be a gross distortion of the truth: it was an entirely collaborative project. The originator of the idea – as with the entire Delphi Club project – was Peter Mantle, the publisher. The work of 30 photographers is included. There was huge input from the very experienced project manager and from Bahamas bird experts. So although my name is on the cover, it is as a participant representing the contributions, camera skills and brainpower of many people.

The book launched to generous enthusiasm and support both on Abaco and beyond, which has continued ever since. We have been astonished by the positive responses to this unique publication for the Bahamas. There is a wider purpose to the book than as a photographic showcase for Abaco birds. All Abaco schools, colleges, libraries and local wildlife organisations have been given free copies for educational purposes. And a percentage of the profits is set aside for local wildlife causes.

Below are some facts and stats. Some people may well have seen these set out elsewhere, but a lot of new people have kindly tuned in to Rolling Harbour in the last 12 months or so, so I will repeat some of the details.

The Guide showcases the rich and varied bird life of Abaco, Bahamas and features both resident and migratory species including endemics rarities and unusual sightings.

The main features are as follows:

  • 272 pages with more than 350 photographs
  • 163 species shown in vivid colour – nearly two-thirds of all the bird species ever recorded for Abaco
  • Every single photograph was taken on Abaco or in Abaco waters
  • All birds are shown in their natural surroundings – no feeders or trails of seed were used
  • Several birds featured are the first ones ever recorded for Abaco or even for the entire Bahamas

  • A total of 30 photographers, both experienced and local amateurs, contributed to the project
  • The book had the generous support of many well-known names of Abaco and Bahamas birding
  • A complete checklist of every bird recorded for Abaco since 1950 up to the date of publication was compiled specially for the book (6 new species have been recorded since then…)
  • A code was devised to show at a glance when you may see a particular bird, and the likelihood of doing so. Birds found at Delphi are also marked
  • Specially commissioned cartographer’s Map of Abaco showing places named in the book

  • Say goodbye to ’37 warbler species on consecutive pages’ misery
  • Say hello to astonishing and unexpected juxtapositions of species

  • The book was printed in Florence, Italy by specialist printers on Grade-1 quality paper
  • Printing took pairs of printers working in 6 hour shifts 33 hours over 3 days to complete
  • The project manager and the author personally oversaw the printing

The book is published by the Delphi Club (contact details below). The project was managed by a publishing specialist in art books. The author is the wildlife blogger more widely known on Abaco and (possibly) beyond as ‘Rolling Harbour’. Oh! So that would in fact be Mrs Harbour and myself. Well well! What were the chances?

*BIRDWATCHER ALERT* A BIG DAY FOR BIRDS EVERYWHERE!

It’s here again – GBD, the second Global Big Day. A chance for anyone and everyone to participate in a worldwide celebration of birds at just the level you choose.

Global Big Day Flyer (Cornell Lab)

No need to try to cover 100 square miles in a day and record 300 species. Unless you want to, of course. You could as easily spend an hour or two in a garden. In a clearing in the coppice. Down a track in the pine forest. Sitting on the beach with a cooler full of beer. Whatever suits you.

As the second Saturday in May, today also happens to be the official IMDB – International Migratory Bird Day – for the U.S. and Canada (the Caribbean is in October – reversed migration routes. Geddit?).

IMBD 2016 poster

However, this post is not primarily about that event, but rather an encouragement to people to join in with some easygoing birding today. And if you happened to want to do it tomorrow, that’s OK too! If you want to send me your checklist (iphone photo should be fine), please do. Or send 2 or 3 best photos, and I’ll post my favourites – though preferably rather than post to my FB page, email to rollingharbour.delphiATgmail.com .

Wherever you happen to be, just take a little time to look for some birds. There are plenty of places you can rule out straight away. Indoors for example. So it means being in the fresh air. And it’s probably best to set an hour or so as a minimum target time to spend on the task.

WHAT DO I NEED?

Keep it simple. A pen that works. A spare pen just in case. A note book or even a large sheet of paper. Binoculars maybe. Camera if you are that way inclined. Sustenance. Maybe a friend for a joint effort. Possibly a bird book. If you have a North American one, it will help with most of the species you are likely to encounter.

In an ideal world you would then upload your checklist officially to eBird by May 17 so that your findings can be included in the global statistics. Or you could pass your record to a local birding group to upload for you. Or just have a bit of fun, why not, and see how many different birds you can find (even if you can’t put a name to them). Last year 268 Caribbean species were recorded. Imagine if one of yours was the only one of its kind to be seen?

WHY DO IT?

The stats gleaned from this initiative, and others like it (‘Shorebird Day’; ‘Warbler Day’ etc) are a good indicator of the state of health of the bird population both in general and by location. Perhaps an area previously having worrying low numbers for a particular species will show an encouraging upswing, indicating a successful breeding season and  / or effective habitat protection initiatives. Or maybe one species will show an unexpectedly low figure, indicating a need for research and the instigation of protection measures.

So every return made for every region in the world is significant; and if you can add 20 species to the count, you will be adding to the vast fund of accumulated knowledge that in the long term helps to preserve the birds that surround us.

Let the count begin…
