HURRICANE UPDATE: GONZALO TRACKS AWAY FROM ABACO, BAHAMAS

STOP PRESS – UPDATE Following yesterday’s post (below), the hurricane’s tendency to track further away from the Bahamas is confirmed by later models, for examples this one from Wunderground. So I think we are officially ‘off-risk’. But Bermuda is definitely not… Anyway, read on a bit and you will find out how hurricanes get their names!

Yesterday I posted on my FB page an NOAA hurricane tracking map update for Hurricane Gonzalo, currently rated Cat. 2 on the SAFFIR-SIMPSON SCALE. It is making its way north through the Caribbean right now, and at one stage the storm cone looked on a possible course for the Bahamas. Abaco has been spared a major cyclone for a couple of years. However memories are very recent of Hurricane Irene (2011) which passed directly over Abaco as a Cat. 3 storm; and Hurricane Sandy (2012) that passed marginally to the east with (at that stage) an intensity of a Cat. 1 before going on to wreak havoc further north. During those ‘extreme weather events’ I posted regularly about them, with tracking maps and photos. At the time of Irene there was remarkable little information around online and I got a huge number of hits – 5000+ in a day, 15,000+ in a week. I also replied to lots of inquiries from the Bahamas, US and Canada, both general (“How are things at Cherokee?”) to very specific (“Do you happen to know if my boat ‘Blowdakidzinheritanz’ moored in Little Harbour is Okay?”).

I  have been surprised at the response the map generated by way of ‘Likes’ and comments expressing relief… So from my current safe distance of precisely 4250.00 miles from Marsh Harbour, I am posting an update with helpful maps and a bit of general hurricane info. The agencies all agree that Gonzalo will hook east as it progresses northwards. The Bahamas outlook is promising, though for example Bermuda looks to be at risk.  There’s more on hurricanes on the page ABACO WEATHER. I always think that Wunderground produce the clearest maps for general purposes, though there’s a great deal more information to be had from the NOAA site, to which there’s a direct link in the Sidebar (I’ve moved it to near the top for the time being).

THE SAFFIR-SIMPSON SCALE

Here is a reminder of how tropical storms and hurricanes are measured for intensity, as decreed by the S-SS, followed by the National Hurricane Center’s explanation of the gradations of relative intensities.

Saffir-Simpson Scale (Wiki) jpgT

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane’s sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. Category 1 and 2 storms are still dangerous, however, and require preventative measures. In the western North Pacific, the term “super typhoon” is used for tropical cyclones with sustained winds exceeding 150 mph.

Category   Sustained Winds Types of Damage Due to Hurricane Winds
1 74-95 mph
64-82 kt
119-153 km/h
Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding and gutters. Large branches of trees will snap and shallowly rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days.
2 96-110 mph
83-95 kt
154-177 km/h
Extremely dangerous winds will cause extensive damage:Well-constructed frame homes could sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted and block numerous roads. Near-total power loss is expected with outages that could last from several days to weeks.
3
(major)
111-129 mph
96-112 kt
178-208 km/h
Devastating damage will occur: Well-built framed homes may incur major damage or removal of roof decking and gable ends. Many trees will be snapped or uprooted, blocking numerous roads. Electricity and water will be unavailable for several days to weeks after the storm passes.
4
(major)
130-156 mph
113-136 kt
209-251 km/h
Catastrophic damage will occur: Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls. Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months.
5
(major)
157 mph or higher
137 kt or higher
252 km/h or higher
Catastrophic damage will occur: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.

BIRDS OF SAN SALVADOR, BAHAMAS: BOOK REVIEW


Birds of San Salvador (cover) JPG

THE BIRDS OF SAN SALVADOR, BAHAMAS

  • Authors: R. Hays Cummins, Mark R. Boardman, Mark L. McPhail
  • Published 1 Jan 2013, 132pp with 400+ images covering 54 species
  • Available spiral bound for $29.95 on Am@zon; and a steal at $3.16 for Kindle (£5.99 in the UK)
  • STOP PRESS Also available on iTunes for iPhone / iPad, where I imagine it looks great. Once downloaded, author Hays says it can be viewed on a Mac, certainly if you have the latest OS X Mavericks. UK price: a very modest £1.99 (= $3.30)

Within a couple of weeks of the decision to use Tom Sheley’s wonderful Bahama Woodstar as the ‘cover bird’ for “THE BIRDS OF ABACO”, another Bahamas bird book was announced. The same colourful and enchanting endemic bird had also commended itself to the authors for their cover. I wrote to Hays Cummins at once to check whether he would mind another Bahamas bird book encroaching on the territory, especially one using the same cover bird into the bargain. He very charmingly said it would be fine and declared his support for our (luckily) rather different project.

It’s been a while since I added to the section BOOKS, but I thought I’d mention this one for two reasons. First, it is described as ‘A Photo Essay of Common Birds’, which in practical terms means that most if not all of the species featured will be common to the northern Bahamas and therefore familiar on Abaco. Secondly, I very much like the format of the book: there are clear photos; and all necessary general information including notes on individual characteristics and similar species is presented in an easily assimilable way. Were the Delphi book not designed to be the 2 kg bird-showcasing non-field guide doorstop it is, the San Salvador book is one I should liked to have produced! Birds of San Salvador (sample page 1) Birds of San Salvador (sample page 2) DESCRIPTION “This enchanting book addresses a need for an important audience, the budding naturalist, which many of our students are. Without fanfare and pomposity, the book presents beautiful and inspiring photos and lively discussion, but does not indulge in the details of the accomplished birder. The authors present information about the natural history of birds on San Salvador, Bahamas, not through the eyes of a professional or advanced birder, but through the eyes and photographic lenses of inquiring educators and naturalists. This book will help capture and catalyze the interests of aspiring birders and will be an asset for introductions to the birds of the Bahamas and neighboring Caribbean. Over 400 images, representing 54 species, are all original and include a variety of behaviors and highlight recognition characteristics. The authors’ aesthetic photography, printed on high quality paper, will help reinforce identification and enjoyment. Birds are organized by habitat (Coastal, Interior, and Lakes & Ponds), not by taxonomic affinities. A taxonomic index is included.” 

I’m pleased to see the decision to depart from the usual taxonomic ordering of species, though I recognise that for a serious field guide that tradition is pretty much sacrosanct. We played around with categories and sub-categories a bit (sea birds, water birds, land birds; big, medium, small; cute, splendid, dull, plug-ugly) before settling on Peter Mantle’s excellent idea of straight alphabetical organisation. For a mainly photographic book this gives an element of surprise to turning the pages, and avoids  e.g. 37 pages of warblers species, mostly yellow, all huddled together.  Birds of San Salvador (sample page 4) Birds of San Salvador (sample page 5) I notice that there is a single Amazon review, a good one, that says “This guide to one of the lesser known islands in the Bahamas is a nice one. While not exhaustive, it covers most of the species likely to be seen on San Salvador. The style is unorthodox for a field guide (elements of humor, gives brief description of species, but no real key field marks), the descriptions, locations on the island, and behaviors make this guide useful for those visiting San Salvador. The photographs are excellent.” Birds of San Salvador (sample page 3)For anyone interested in a useful reference guide to the common birds of Abaco, and in possession of a Kindle, this book is easily worth getting electronically.  ‘To be brutally honest’ (™ Sandy Walker), I’d like in due course to produce a small book very like this for Abaco, but it would obviously be naked plagiarism to do that, so of course I won’t. Still, all the same…

ABACO: COLOURFUL EVEN DURING TROPICAL STORM ARTHUR

ABACO: COLOURFUL EVEN DURING TROPICAL STORM ARTHUR

As Tropical Storm Arthur blows northwards increasing in strength, Abaco has begun to get its sunshine back. TS Arthur, then defined as a Tropical Depression, hung around over the Northern Bahamas for four days or so before finally clearing. In the past I wrote daily posts about Hurricane Irene and Hurricane Sandy at a time when information was surprisingly hard to come by. Now everyone is on Facebook and it’s easy to post (or find) cyclone reports, maps, path projections and so on. I’m always struck by the contrast between the bleak, dark-clouded snaps that people put up on their FB pages and the cheerfully coloured weather maps that mark the passage of the storm. Here are a few for Tropical Depression Arthur when over Abaco and moving north, taken from the most useful mainstream sites. My favourite is the National Hurricane Center NOAA where the graphic information is presented in a number of formats. However MIKE’S WEATHER PAGE is a good first resort for information – ‘Like’ it and you’ll get the reports you need. For a plethora of graphics on every hurricane aspect, move on to his website http://www.spaghettimodels.com

Whenever there’s a bad storm or a hurricane, it’s worth visiting the NASA ISS site for dramatic images from the Space Station. The following link will take you to a dramatic photo of Hurricane Irene in 2011 HERE There’s a search facility on the site. This is a fine image of TS Arthur, illustrating the characteristic swirl pattern of a tropical storm.

Compare the bright graphics above with the reality for those under the massed clouds in strong wind and scything rain… Cheers for these vividly gloomy images to Julias Sawyer, Cindy James Pinder and Albury’s Ferries (who post almost daily images of Abaco weather as the ‘Donnies’ ply the seas between the main island and the outlying Cays with their passengers and cargo…)

I can’t resist adding an ‘Abaco summer weather’ photograph taken by Amanda Diedrick on Green Turtle Cay. There was a passing bout of bad weather was a couple of weeks back, and Amanda managed to take this extraordinary photo of a bolt of forked lightning apparently burning straight through a small cloud. It’s difficult to get a good lightning shot without special cameras, compartic lenses, Fitzallan filters, aperture reticulators and the like. She did it!*

The start of the summer season is a good time to roll out the Saffir-Simpson Scale, from which you will see how the various intensities of storm are graded. It’s colourful as well.

ROLLING HARBOUR, ABACO – THE GEOGRAPHICAL FEATURE

ROLLING HARBOUR, ABACO – THE GEOGRAPHICAL FEATURE

Rolling Harbour, location of the Delphi Club, is a mile-long curving sandy bay on the east side of South Abaco, half an hour’s drive south of Marsh Harbour. It is marked on a handful of old maps and a couple of more recent ones. Other than that, it keeps itself pretty much to itself. Here’s a 30-second, 180º panoramic movie from the beach. Blue skies. Blue water. Turquoise water. White sand. 4250 miles from where I am right now…

MARSH HARBOUR ONLINE MUSEUM: A NEW RESOURCE FOR OLD ABACO

There’s a new arrival on Facebook, and the word is already out. Within 12 hours the page has gained 119 followers*. Already there are some wonderful old photos of family groups and MH residents. Some are named; some may be waiting for someone to recognise them. The header image (thanks for use permission, MHOM) is both instantly recognisable yet puzzling. Is that Snappas over there… no, look, there…? To get straight to the page, click HERE. I guess they’ll want to hear from anyone who has old photos or postcards of MH; or who can help with ID of people and places.

There is a similar resource for GREEN TURTLE CAY, where Amanda has a great blog LITTLE HOUSE BY THE FERRY. In part it records the restoration of her family home. However, it is also packed with old photos (with people invited to name the unknowns) and details of a fascinating genealogy project through DNA samples. MAN-O-WAR CAY has a Facebook Group called Man-o-War Cay and Abaco Family History with similar aims. HOPE TOWN has a very active Facebook page fronted by the iconic LIGHTHOUSE. And so on. Not forgetting the museums such as the WYANNIE MALONE MUSEUM, Hope Town and the MAN-O-WAR CAY HERITAGE MUSEUM.

I am neither Abaconian nor even a second-homer, so I tread lightly in these matters for obvious reasons. However, I have posted a few items about Abaco’s history from time to time so I’ll add a few links below in case anyone is tempted to investigate further. Meanwhile, I notice that in the time I have put this post together, the followers for MHOM have risen to 139…

ABACO: AN IMPORTANT BIRDING AREA IN THE BAHAMAS

The Bahamas National Trust BNT is one of several organisations in the Bahamas responsible for conservation across the widely scattered islands of the Bahamas. One of its tasks is to look after the birds and their habitat, and from time to time the Trust publishes articles about their work. The Abaco-related material below is taken from a much longer article by Predensa Moore and Lynn Gape that covers the whole area, and concerns the importance of Abaco as a prime Bird Area. This applies in particular to Little Abaco and the Northern Cays; and to the large area of South Abaco that incorporates the National Park. The bird images used show some Abaco speciality birds mentioned by the BNT in their material.

PHOTOGENIC ENDEMICS: BAHAMA YELLOWTHROATS ON ABACO

PHOTOGENIC ENDEMICS: BAHAMA YELLOWTHROATS ON ABACO

I’ve been keeping this little bird up my capacious avian-friendly sleeve for a while. In June we took a truck and headed for deep backcountry to the edge of the pine forests and beyond to see what we could find in the way of birdlife. Good choice – the answer was ‘plenty’.Bahama Yellowthroat Abaco 5

Among the birds we encountered were the endemic Bahama swallows, hairy woodpeckers, red-tailed hawks, kingbirds, red-legged thrushes, red-winged blackbirds, western spindalises, tobacco doves, La Sagra’s flycatchers, crescent-eyed pewees with a nest and eggs, a wonderful ‘booming display’ by antillean nighthawks courting during an early evening fly hatch**… and Bahama yellowthroats Geothlypis rostrata.Bahama Yellowthroat Abaco 1

The illustrative photos are of poor quality, but rather than blame my camera (as I am only too ready to do), I plead ‘overexcitement’ in mitigation. Of the 4 endemic species on Abaco, this was the only one I’d never seen. There was a tweeting noise on the edge of an abandoned sugar cane field (above), followed by  some rustling… and out fluttered this bird, crossing the track right by us and landing quite close to inspect us. Bahama Yellowthroat Abaco 2

This striking bird, with its Zorro mask and bright yellow body, is an endearing mix of shy and inquisitive. Only the males have the mask – the females are less colourful, though naturally equally interesting… Bahama Yellowthroat Abaco 8

Yellowthroats are responsive to pishing, and once lured from cover they may happily remain on low-to-medium height branches or on a shrub, watching you watching them.Bahama Yellowthroat Abaco 3

Their song is quite easily imitated, and that may also bring them into the open – a source of immense satisfaction to the amateur (me) if it works. Here’s an example, courtesy of my iPH@NE METHOD for bird recording. It’s the call at the start and the end.

The one we watched had plenty to sing about – it’s just a shame that my images are so poor, because in some you can see its tiny tongue. A bit too blurry, though, even by my own moderate standards for inclusion.Bahama Yellowthroat Abaco 4

At a formative stage of this blog, I did a short post about the endemic Bahama Yellowthroat and its comparisons with the similar and better-known Common Yellowthroat, which is also found in the Bahamas. You can read it HERE. There’s a female shown, a video, and an unacknowledged debt to Wiki or similar source, I can’t help but notice…Bahama Yellowthroat Abaco 6

**ANTILLEAN NIGHTHAWKS AND THE ‘BOOMING DISPLAY’

Common Nighthawk Photo “On summer evenings, keep an eye and an ear out for the male Nighthawk’s dramatic “booming” display flight. Flying at a height slightly above the treetops, he abruptly dives for the ground. As he peels out of his dive (sometimes just a few meters from the ground) he flexes his wings downward, and the air rushing across his wingtips makes a deep booming or whooshing sound, as if a racecar has just passed by. The dives may be directed at females, territorial intruders, and even people.” We found ourselves right in the middle of one of these astounding displays, with maybe 100 birds behaving exactly as described, often whooshing within inches of our heads. I’ll post some more about it in due course. Credits: Philip Simmons; All About Birds (Cornell Lab)
