PAN’S LABYRINTH, DAN’S CAVE: ABACO’S ASTOUNDING UNDERGROUND WORLD (5)

                                  PAN’S LABYRINTH, DAN’S CAVE                                      ABACO’S ASTOUNDING UNDERGROUND WORLD (5)

June brought news of a wonderful exploration of a near-inaccessible part of the Dan’s Cave complex in South Abaco, deep under the acres of pine forest. The expedition involved Brian Kakuk, Steve Bogaerts, Hp Hartmann, and a ‘Razor’ sidemount camera.  As Steve later wrote, “…I had the privilege to film probably the most beautiful caves in the world and to take my camera to places where nobody else has filmed before. Special thanks to Brian Kakuk to make this video happen”.

Brian’s account of his first exploration of Pan’s Labyrinth in 2010 (link below, scroll down the page you reach) is extraordinary. The difficulties faced in negotiating the narrowest of passages while carrying essential equipment makes for tense reading…

A VISIT TO BIMINI’S MARINE ENVIRONMENT (2)

A VISIT TO BIMINI’S MARINE ENVIRONMENT (2)

In this second part of the look at Bimini’s Marine Protected Area Campaign and the photographs that illustrate the vital importance of the mangroves, reefs, sea grass and pristine sea to marine life, it’s time to look at some of the the smaller sea creatures in their underwater habitat. Many of these are vulnerable to changes in their environment; some are already rare.

SILVERSIDES

At first glance you may wonder why these little fish are worth including. The answer lies in the food chain. The clean environment in which these bait fish thrive provides food for larger species and so on up the chain… If silversides ceased to exist, a vital source of marine nutrition would be lost.

HOW TO CATCH FISH EFFECTIVELY, OSPREY-STYLE

HOW TO CATCH FISH EFFECTIVELY, OSPREY-STYLE

I have featured the wonderful photography of Phil Lanoue before. He specialises in taking sequences of the larger birds, many of them as they hunt for fish: herons, egrets, anhingas – and ospreys. Here is a remarkable sequence of an osprey showing its fishing skills, with a surprise ending that I won’t give away.

“CLINGING TO THE WRECKAGE”: BAHAMAS CLINGING CRABS

“CLINGING TO THE WRECKAGE”: BAHAMAS CLINGING CRABS

The Clinging Crab Mithrax spinosissimus answers to a number of names: West Indian spider crab, channel clinging crab, reef or spiny spider crab, or coral crab. It is found throughout the waters of South Florida and the Caribbean. Clinging Crab ©Melinda Riger @ G B Scuba copy

These are crabs of the reef, or indeed of the wrecks that may be found around reefs. Some of the crabs in this post have chosen wrecks as their home – in the header image the crab is living inside the smoke stack of ‘Theo’s Wreck’, Grand Bahama.Clinging Crab ©Melinda Riger @ GB Scuba

The clinging crab is believed to be omniverous, its main diet being algae and carrion. They can grow to 2 kg, and it is the largest species of reef crab found in the Caribbean.Clinging Crab © Melinda Riger @ G B Scuba

The clinging crab / West Indian spider crab is (apparently) not commercially harvested for its meat. However, it is said to be delicious. Any views on this welcome in the comments section! If you want to know more about how to prepare (“a real challenge”) and cook a spider crab, check out this LINK

Life on the reef can be dangerous. This crab has lost some legs: its clinging powers are somewhat curtailed…Clinging Crab (legs missing) ©Melinda Riger @ G B Scuba

A VISIT TO BIMINI’S MARINE ENVIRONMENT (1)

Abaco is fortunate already to have special conservation areas, both on land (e.g. the huge National Park) and at sea (e.g. Fowl Cay Marine Preserve). Other preserves are in active stages of development. Elsewhere in the Bahamas, where the natural life is equally wonderful, battles are being fought to protect pristine habitat from the encroachments of modern life such as unsuitable development (or development in unsuitable locations). For this first look at Bimini, I am most grateful to Bimini’s Marine Protected Area Campaign  for permission to use some of their wonderful photographic archive that illustrates the vital importance of the mangroves, reefs, sea grass and pristine sea to marine life large and small. It’s worth checking out the background and surrounding context of these images to see the sort of habitat the creatures depicted prefer. This post features some of the larger species.

‘CHECK OUT THE WEB’: SEMIPALMATED PLOVERS ON ABACO


Semi-Palmated Plover, Abaco (Alex Hughes)

‘CHECK OUT THE WEB’: SEMIPALMATED PLOVERS ON ABACO

“Semipalmated”. You what? Come again? Ehhhh? My reactions to the word until embarrassingly recently. In fact until the steep learning curve involved in writing a bird book made some all of the terminology clearer. Plovers and sandpipers both have semipalmated versions, and I’ll take the semipalmated plover (Charadrius semipalmatus) first.

Semipalmated Plover, Abaco (Woody Bracey)

WHAT SHOULD I LOOK FOR?

A small shorebird with a grey-brown back and wings, a white underside with a single black neck band, and orange legs. They have a brown cap, a white forehead, a black eye mask and a short black bill with an orange base to it. And feet to be discussed below.Semi-palmated Plover WB P1001211 copySemipalmated Plover, Abaco (Tony Hepburn)

WHERE DO THEY LIVE?

Their summer home and breeding habitat is on the beaches and flats of northern Canada and Alaska. They nest in scrapes on the ground right out in the open. In the Autumn these little birds set off on long journeys south to warmer climes until Spring: the coasts of the southern states, Caribbean and South America. On Abaco, they are fairly common in certain areas including the beach at Delphi. Like other plovers, these  birds are gregarious and will mix in with other shorebirds – which can make them hard to pick out in the crowd.Semipalmated Plover, Abaco (Charles Skinner)

GET ON WITH THE ‘SEMIPALMATED’ BIT, PLEASE

‘Semipalmated’ refers to the partial webbing between their toes. There are different degrees of palmation, as these handy graphics demonstrate:

Semipalmate: in practice, very hard so see in the field e.g. plovers & sandpipers semipalmate

Palmate: full webbing across the ‘front’ 3 toes, e.g. gulls

palmate

Totipalmate: all toes are fully webbed e.g. cormorants

totipalmate

Nonpalmate: please supply own imagination 

Gregarious flight: there are sandpipers in the mix (clue: long bills)Semipalmated Plover, Abaco (Alex Hughes)

WHAT DO THESE BIRDS EAT?

Semipalmated plovers are much like any other small shorebird foraging on beaches and foreshores. They eat insects, crustaceans and worms. Here is a bird in a promising place for its preferred diet.

ANYTHING ELSE TO LOOK OUT FOR?

Like other plover species – Wilson’s and Killdeer for example – a semipalmated will  use the ‘broken wing’ ploy to lure a predator away from a nest and the eggs or chicks in it. As it flops about pathetically on the sand looking vulnerable, it actually moves gradually further away from the nest. If it comes to the crunch it is able to take wing rapidly, leaving a very puzzled predator behind.Semipalmated_Plover,_broken_wing_display (D Gordon E Robertson)

BLACK-BELLIED WHISTLING DUCKS REVISITED…


Black-bellied Whistling Duck

BLACK-BELLIED WHISTLING DUCKS REVISITED…

The first ever Black-bellied Whistling Ducks recorded for Abaco arrived last June. Six birds turned up on South Abaco in the Crossing Rocks area and slowly worked their way north via Delphi, Bahama Palm Shores and Casuarina. They split up into smaller groups. Two were seen near the airport. Eventually, after 3 weeks or so, the sightings and reports ceased. The BBWDs had moved on, presumably to Florida. Black-bellied Whistling Ducks 10

I mention them now because this June, a flock of 13 birds arrived on a golf course in Bermuda. The only previous recorded sighting of the species had been a single bird spotted in 2006. Within a couple of weeks, the birds had disappeared again. It’s strange that in consecutive years, June sightings have occurred on two islands  where they are not a known species. I happen to have taken some photos of BBWDs elsewhere in the meantime, and I thought these pretty ducks deserved further exposure…
