 ABACO’S ENDEMIC BIRDS: MAKING A CASE FOR PROTECTION

I recently wrote a post showcasing the 4 Bahamas endemic bird species found on Abaco: swallow, warbler, woodstar hummingbird, and yellowthroat. You can read it and see some great photos HERE. Sadly, the magnificent oriole, extant on Abaco for centuries, was extirpated in the 1990s. You can still see them but only on Andros; and the population there is barely sustainable – there are only 260 remaining. Still, on Abaco there remain four of the endemic species to conserve and care for.

The Bahamas National Trust BNT has produced 6 brief but informative illustrated ‘cards’ about the Bahamas endemics. They deserve a wide audience, especially in view of the threats to some species for reasons that include habitat loss and increasing development. New Providence lost its subspecies of Bahama Yellowthroat within the last 20 years. Let’s hope that Abaco can hold onto its speciality birds for the future.

FIVE STARS: BAHAMAS ENDEMIC BIRDS (FOUR FROM ABACO)

The Caribbean Endemic Bird Festival is underway. You can find out more on the CARIBBEAN BIRDS FESTIVALS Facebook page. Abaco is fortunate to be home to 4 of the 5 endemic Bahamas species. The fifth, the beautiful BAHAMA ORIOLE Icterus northropi, was found on both Abaco and Andros until the 1990s, when it sadly became extirpated from Abaco. Now found only on Andros, there are thought to be fewer than 300 Orioles left – a barely sustainable number. The species is unsurprisingly IUCN listed as critically endangered. Here’s a picture of one as a reminder of what Abaco is now missing…

Abaco’s four endemic species are the tiny Bahama Woodstar hummingbird, the Bahama Yellowthroat, the Bahama Warbler (since 2011), and the Bahama Swallow. All are of course permanent breeding residents on Abaco and its outer Cays. None is exclusive to Abaco; all are relatively plentiful. The Woodstar is perhaps the hardest to find, not least because it competes territorially with the Cuban Emerald hummingbird. Even Woodstars can be found easily in some areas – Man-o-War Cay is a good place for them, for example. Here are some striking images of these four endemic bird species taken from the archives for “The Birds of Abaco” published last month.

“The Delphi Club Guide to the Birds of Abaco”  was published as limited edition of 500 and has only been for sale for 8 weeks or so exclusively through the Delphi Club. Yesterday, we passed a happy milestone in that short time as the 250th copy was sold. Complimentary copies have also been donated to every school and relevant education department on Abaco to tie in with the excellent policy of teaching children from an early age the value of the natural world around them, the importance of its ecology, and the need for its conservation. The cover bird for the book was easy to choose – it just had to be a male Woodstar in all his glory with his splendid purple ‘gorget’.

BIRDS, PLASTIC & CONSERVATION: A CONTROVERSIAL AD…

BIRDS, PLASTIC & CONSERVATION: A CONTROVERSIAL AD…

Rolling Harbour is a broadly neutral territory. We occasionally do ‘opinionated’ round here. We are not afraid to express views. But we try to avoid controversy and in particular, politics in its broadest sense. There have been occasional lapses into outrage – one example was the huge cruise ship taking a shortcut (allegedly, I had better add) that trashed significant areas of irreplaceable coral reef and smeared poisonous anti-fouling paint along the seabed, affecting reef life for decades and… Stop me right there!

The most sensitive area is conservation. Some issues are straightforward; with others the balance of what is right and wrong is more debatable. One particular aspect that can be problematic is in the presentation of information. We are all familiar with charity appeals that cajole with images of happy children or sweet puppies. We also see the ones with horrific images that are uncomfortable or even downright unpleasant to look at. Both can be powerful and valid  ways to raise awareness and attract support. Some of the more extreme images used may actually have the effect of repelling people. The same is true with conservation projects. There are ones illustrated with images that make you go ‘ahhhh’ and smile; others are undeniably distressing and will make you wince with uneasiness.

See how you react to this 45 second video from Australia. It is made by Greenpeace – itself a controversial organisation in some eyes – and concerns Coke, plastic and birds. I had no idea what to expect, and it gave me a jolt. It has been the subject of legal action, of alleged censorship and interference from powerful lobbies, and a sizzling amount of anger. It won’t take you long to watch it. Compare how you feel during the first ten seconds with how you feel 30 seconds later…

THE CONCH QUEST OF ABACO…

THE CONCH QUEST OF ABACO…

Conchs are gastropods. They are food. They are decoration (anyway, the shells are). For some, they are a living. And on Abaco they are everywhere – alive in the waters, and as shells scattered on  beaches or piled up outside restaurants. So the quest for conch is an easy one. There are fears of overfishing, however, and an active organisation The Bahamas National Conchservation Campaign exists to protect them. Another similar Bahamas organisation is Community Conch.conchs-at-sandy-point-1 We found a nice half-buried conch shell at Sandy Point. It was full of sand grains and tiny shells – mini gastropods and bivalves – that took some time to wash out of the spiralling internal structure. Here are some studies of the shell. IMG_2438IMG_2442IMG_2444IMG_2445IMG_2448IMG_5279IMG_5278 The damage to the shell above is the place where it has been bashed in to enable removal of the occupant. In order to do so, it is necessary to break the strong vacuum that would prevent extraction if you tried by the conventional route. Effectively the conch anchors itself to its shell and must be cut out. The best way to make the hole is with the spiral tip of another conch. This breaks the suction and enables you to prise out the occupant…

MARINE DEBRIS? NO THANKS! 10 FACTS FROM NOAA


Ten Things You Should Know About Marine Debris

Entangled-harbor-seal NOAA Marine Debris
Our waterways are littered with stuff that doesn’t belong in them. Plastic bags, cigarette butts, fishing nets, sunken vessels, glass bottles, abandoned crab traps…the list is endless. Some of this marine debris comes from human activity at sea, and some of it makes its way into our waterways from land.
While we know that marine debris is bad for the environment, harms wildlife, and threatens human health and navigation, there is much we don’t know. How much marine debris is in our environment? How long does it last? How harmful is it to natural resources or human health and safety? How long does it take to break down in the water? The NOAA Marine Debris Program is finding answers to these questions.

1. It doesn’t stay put

While a lot of debris sinks, much also floats. Once this marine debris enters the ocean, it moves via oceanic currents and atmospheric winds. Factors that affect currents and winds (for example, El Niño and seasonal changes) also affect the movement of marine debris in the ocean. Debris is often carried far from its origin, which makes it difficult to determine exactly where an item came from.

2. It comes in many forms

Marine debris comes in many forms, ranging from small plastic cigarette butts to 4,000-pound derelict fishing nets. Plastic bags, glass, metal, Styrofoam, tires, derelict fishing gear, and abandoned vessels are all examples of debris that often ends up in our waterways.img_0510_ss-1

3. It’s your problem, too

Marine debris is a problem for all of us. It affects everything from the environment to the economy; from fishing and navigation to human health and safety; from the tiniest coral polyps to giant blue whales.

4. NOAA is fighting this problem

The NOAA Marine Debris Program works in the U.S. and around the world to research, reduce, and prevent debris in our oceans and coastal waterways. Much of this work is done in partnership with other agencies, non-governmental organizations, academia, industry, and private businesses.The Marine Debris Research, Prevention, and Reduction Act, signed into law in 2006, formally created the Marine Debris Program. The Act directs NOAA to map, identify, measure impacts of, remove, and prevent marine debris.

5. Some debris is being turned into energy

Abandoned and lost fishing gear is a big problem. It entangles and kills marine life and is a hazard to navigation. Based on a model program in Hawaii, the Fishing for Energy program was formed in 2008 to tackle this problem with creative new ideas. The program is a partnership between NOAA, Covanta Energy Corporation, National Fish and Wildlife Foundation, and Schnitzer Steel.This program offers the fishing community a no-cost way to dispose of old or derelict fishing gear. Once removed from the environment, the gear is transported to the nearest Covanta Energy-from-Waste facility. About one ton of derelict nets creates enough electricity to power one home for 25 days!

6. Marine debris can hurt or kill animals

Marine debris may be mistaken by some animals for food or eaten accidently. Often, larger items like nets, fishing line, and abandoned crab pots snare or trap animals. Entanglement can lead to injury, illness, suffocation, starvation, and even death. NOAA is working with many partners to tackle this problem by reducing and preventing marine debris in our oceans and waterways.

7. There’s a lot to learn about this problem

We know that marine debris is a big problem, but there’s much we need to learn. NOAA funds projects across the country and works with scientists and experts around the globe to better understand how marine debris moves, where it comes from, and how it affects the environment. This knowledge will help us find better ways to tackle the problem.

8. You can help us get the word out!

The NOAA Marine Debris Program offers a heap of creative products to get the word out about marine debris. Looking for brochures, posters, fact sheets, or guidebooks? We’ve got those. Like videos? We’ve got those, too. We even have a blog! You’ll find it all online.

9. This is a global problem.

Marine debris is a global problem that requires global solutions. NOAA experts work with scientists and organizations around the world to share lessons learned, discover what programs work best, and map out future strategies to fight this problem.

10. Small steps lead to big results

Fighting the marine debris problem begins at home.

  • – Try to cut back on the amount of trash you produce.
  • – Opt for reusable items instead of single-use products.
  • – Recycle as much of your trash as you can.
  • – Join local efforts to pick up trash.
  • – Keep streets, sidewalks, parking lots, and storm drains free of trash—they can empty into our oceans and waterways.

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.
