TURTLEY AMAZING: HAWKSBILL TURTLES IN THE BAHAMAS

The Bahamas has breeding populations of 5 of the world’s 7 sea turtle species - Green, Loggerhead, Hawksbill, Leatherback and Kemp’s Ridley turtles (the other two are Olive Ridley – occasionally found in the Bahamas – and Flatback turtles). All are endangered. There’s no getting away from the fact that Man and Man’s activities are now the primary threats. The IUCN ratings below make for sad reading. To see some of the problems, check out THREATS TO SEA TURTLES

Admire the photos here of Hawksbill Turtles Eretmochelys imbricata while you can – the species is IUCN red-listed and I can’t improve on this explanatory display…Hawksbill Turtle Eretmochelys imbricata (IUCN Red List)

I did ask myself whether including this shot might show a lack of sensitivity for the essential dignity of a fine species, infringing its Testudinal rights. But overall, I feel the public interest is best  served by showing it. Anyway, it has plainly discovered something very tasty to get stuck into, so it won’t be unduly bothered.

 The SEA TURTLE CONSERVANCY has produced an outstanding series of posters similar to the LOXAHATCHEE posters about corals, conchs, sea grass, bonefish etc. Here is their Hawksbill one, with illustrations by artist DAWN WITHERINGTON. Click the link to reach her website and see her excellent scientific drawings and a lot more besides. This excellent poster contains pretty much all the details you need to hold your own in any hawksbill-related conversation. You can enlarge it by doing that thing with 2 fingers on your track pad thingy.

I rather like this video from Andros, with the turtle’s gentle tolerance while being approached by a photographer until at last  it decides to move slowly off. The music’s a bit annoying though – it doesn’t really fit the scene IMO.

CORMORANTS: RAPACIOUS PESCATARIAN SEA-RAVENS


Cormorant WWT 12

CORMORANTS: RAPACIOUS PESCATARIAN SEA-RAVENS

Cormorants are strange creatures. Strange to look at. Strange in their relationship with humans – love / hate in fishing terms and good / evil in mythology. Strangely useless for poetry, since – like the words ‘purple’ and ‘orange’ – there is no pure rhyme for the word cormorant. But they are undeniably striking, and a cormorant on the Abaco Marls effortlessly gliding inches above the water is an impressive sight.

Cormorant WWT 1Cormorant WWT 5

The cormorant’s name originates from the Latin name ‘Corvus Marinus’, the Sea Raven. Cormorants belong to the ‘Pelican’ order of birds known as the pelecaniformes that also encompasses tropicbirds, frigatebirds and anhingas. Worldwide, there are around 40 different species of cormorant. In many parts of the world, this seabird has established itself inland. Angling communities are increasingly concerned by the spread of this bird along productive fishing rivers, often far from the sea shore. In the UK as elsewhere they are very bad news for prime fishing rivers.

The birds here were photographed in the UK on Halloween. While the world was preparing to immerse up to its neck in blood, guts, gore and spider webs, I was out armed only with a camera in unseasonably warm sunshine. So these are Great Cormorants Phalacrocorax carbo, the species found in the UK. They a remarkably similar to the Double-crested Cormorants Phalacrocorax auritus found on Abaco but larger and with a pale cheek and upper neck. This was a perfect day for the cormorants to enjoy their preening and wing-drying routines.

Atala Hairstreak Butterfly, Abaco 6

‘ATALA FASCINATING’: THE LIFECYCLE OF THE ATALA  HAIRSTREAK ON ABACO

I have posted about several of the wonderful butterfly species the live on Abaco, but my favourite will always be the small but beautiful Atala Hairstreak Eumaeus atala. Its ‘look-at-me’ bright orange abdomen, black wings and the curious luminescent bright blue spots that even cover its legs and head are unmistakeable. These butterflies favour the coontie plant – especially for egg-laying – but they can be seen almost anywhere as far as I can see, though I have never seen one right by a beach. 

I’ve posted before about the lifecycle of the Atala, but I have never had a chance to show the complete post-egg process from caterpillar to triumphantly emergent butterfly actually recorded on Abaco until now. Thanks to Rhonda Pearce, her patience and her skill with a camera, the following sequence of photos shows in detail the various stages of metamorphosis.

THINGS TO LOOK OUT FOR

  • The little hairs on the caterpillars (larvae)
  • The dark gluey-looking shed skins
  • The delicate silky threads as the chrysalis forms
  • The butterfly emerges upside down, enabling it to uncrumple & spread its wings to dry

PS Sorry, I’ve been very po-faced and not mentioned Halloween. Everyone else is covered in blood, guts and gore, so I reckon the market is saturated. Also I get the wrong end of the ‘Trick or Treat’ stick. I carefully prepare 2 lots of choccy-based sweets. One is delicious. The other contains chilli. If the callers are nice, they get the Treat. If not, they get the Trick. That must be right, surely. I can listen to them hawking and barfing as they run off into the night…. [No children were hurt in the making of this story…]

PLOVER LOVER? PIPING PLOVERS ON ABACO (3)

PLOVER LOVER? PIPING PLOVERS ON ABACO (3)

So much to post about – what to choose? Well, the fall migration is still in full swing, with warblers hurtling across land and sea to Abaco in large numbers for their overwintering. Palm warblers are currently arriving. However I’m going to stick with shorebirds for now, and one of the rarer winter visitors, the Piping Plover. I have some more great photos from Danny Sauvageau in Florida, who tirelessly patrols the plover resting areas to record the banded ones so that their origin can be determined. This research assists with vital habitat conservation programs at each end of the migration. There are only 8000 of these little birds left in the world and without protection there’ll be none before you can say “oh dear, very pretty, they’re gone, what a pity…”

RING BLING & FLAG TAGS

The postions, colours and numbering of the rings and tags on these plovers identify individual birds, the location of their summer breeding grounds and so on. Dispersal and migration patterns of each bird can be recorded and specific facts – age for example – can be monitored.Piping Plover (Danny Sauvageau) 2

PIPL IN FLIGHT – AN AMAZING IMAGE

On the very day I was about to press the ‘publish’ button on this post, look what just flew in from Danny’s beach in Fl.! This is an outstanding photo of a PIPL in flight – you can even see its shadow on the sand. I have a few shots of these birds flying in groups over the sea but apart from a general impression of PIPL-ness, they could really be any small shorebirds travelling fast on the wing. This one is special. Piping Plover in flight (Fl., Danny Sauvageau)

ABACO PIPL NEWS

Piping plovers have already arrived on Abaco. Casuarina beach is a promising place to look. Rhonda Pearce sent me this nice photo taken on the point (see my map). This pretty bird looks as though it has a black tag. However Todd Pover of CONSERVE WILDLIFE NEW JERSEY who also monitors the Abaco end of the migration thinks it may just be a piece of wrack – black tags are not usually used.

If anyone sees a piping plover and has a camera handy, I’d be very pleased to receive any photos, especially showing rings if possible - or indeed ringless legs, which is also informative to the monitors. If it turns out to be a Wilson’s Plover, no matter: they are fine birds in their own right!

Finally a quick reminder about Danny’s Kickstarter project “Saving Endangered Piping Plovers through Photography” and his presentation explaining how his photography in PIPL resting areas during their migrations can help to map and complete the picture of this vulnerable species to enable their protection.

You can reach Danny’s film by clicking the link DANNY’S FILM and you will see some fabulous footage of these little birds scuttling around on the beach, looking enchanting; and the commentary will explain the importance of the the birds and the research into their conservation.

‘WTF?’ IN BAHAMAS WATERS (3) : LETTUCE SEA SLUG

  ‘WTF?’ IN BAHAMAS WATERS (3): LETTUCE SEA SLUG

The ‘WTF’ series so far has covered Bahamas reef fish on the bizarre end of the unusual-to-completely-weird appearance spectrum. And it has stood, of course, for ‘What’s That Fish?’. Today, it doesn’t. The feature creature isn’t a fish at all; it looks like a plant; it is in fact a SACOGLOSSAN - specifically the Lettuce Sea Slug Elysia crispata

The head end is on the left…Lettuce Sea Slug ©Melinda Riger @ G B Scuba copy

The name ‘sacoglossan’ literally means ‘sap-sucker’ (the sapsucker bird has a different latin name, however). And the slug’s frilly edges supposedly resemble certain types of curly lettuce. I’ve no idea where the ‘crispata’ comes from, but I am sure it doesn’t relate to crisp lettuce. These are creatures of shallow, clear waters such as the sub-tropical reefs of the Bahamas.

 ‘SOLAR POWERED SLUGS’

This isn’t a technical forum and too much science hurts my head. This species primarily lives off algae. However I give you the word KLEPTOPLASTY to drop into your conversation. In a sentence, algae is eaten but only partially digested; certain elements are stored to produce photosynthesis by which light is converted to energy and the slug can live without food. But baffle your neighbour at dinner, why not, by summarising the process as “chloroplast symbiosis”. Meanwhile, I’m fetching a beer.

Lettuce Sea Slug ©Melinda Riger @ GB Scuba copy

My research suggests that very little is known about the mating behaviour of these slugs. The pair shown below may be exploring the possibilities, or at least trying to work out which end is which. One is easy to tell, but the other? Time to make our excuses and leave…

HOW FAST, EXACTLY, DOES A LETTUCE SEA SLUG MOVE?

This rather beautiful video from ‘CORAL MORPHOLOGIC’ will reveal all. You’ll soon see that progress is very slow. I recommend watching the first 30 seconds and you’ll get the idea. If you choose to persist, you will see the slug sort of turn a corner to the left.

STANDIN’ ON THE DOCK OF THE BAY: GREAT BLUE HERON ON ABACO

STANDIN’ ON THE DOCK OF THE BAY: GREAT BLUE HERON ON ABACO

The occasion: a trip to Sandy Point for a lunch party at the legendary Nancy’s in honour of  Sandy Walker at the end of his 5 years as manager of the Delphi Club. A pair of brown pelicans on the nearby dock were clumsily flying around, diving, perching, drying their feathers, then repeating the cycle. In a quiet moment I slipped away to watch them – and a Great Blue Heron landed quite close by me. So as well as taking photos of the pelicans, I pointed the camera at the heron from time to time. My favourite view is of it standing proudly on the edge of the dock, with the truly azure sea behind it (header and final image).

THE PERILS OF A CAMERA UPGRADE

[PHOTOGRAPHIC INTERLUDE - SKIP IF EASILY BORED BY SUCH THINGS]

I don’t have a fancy camera. I would never get the settings right before the bird had flown. Or died, even. So I had been using a Panasonic Lumix FZ45 kindly given to me by Mrs RH in a benign moment, possibly Christmas. Then I made a classic error of upgrading to an FZ72 with an alleged massive 60X zoom. Brilliant, I thought. Big mistake. My old camera has a Leica lens. Used with care and a lens extension (zeugma score!), it is / I am occasionally capable of taking pin-sharp photos. The upgrade camera’s lens turned out not to be a Leica. Almost all the shots I took were ‘soft’, the more so using the zoom. A soft photo taken with a less good lens, zoomed 60X, will never be a better photo. Just an even softer one. I wish I’d had Old Faithful with me instead. When we got home, I immediately dug out OF and sold 60X disappointment. OF is now reinstated as my BF.  

The shots of this heron mostly turned out fairly well, largely because it stayed quite close to me. It flew off a couple of times, then returned to the edge of the dock. Here are a few close-up views of the heron selected from the various pics I took, showing some of the details of this fine bird.

ROLLING HARBOUR MUSICAL DIGRESSION

Otis Redding recorded ‘Sittin’ on the Dock of the Bay’, arguably his greatest moment, in 1967 a matter of days before he died in a plane crash. The record became the first ever posthumous US Chart #1 (#3 in UK). I’ve dug out a video compo by the excellent Rhino outfit that disinters or at least recycles gems from our musical heritage. It’s not just the voice of Otis Redding that makes this song so poignant and so good – Steve Cropper’s guitar is outstanding too.

Guitarists out there – you want a ‘Chase Chart’, don’t you?

“OL’ BLUE EYES”: WHITE-WINGED DOVES ON ABACO

“OL’ BLUE EYES”: WHITE-WINGED DOVES ON ABACO

The White-winged Dove Zenaida asiatica  is an easily recognised dove species, being the only one on Abaco with conspicuous white wing markings. The prominent blue eye-rings are another unusual feature of this bird. The blue is skin and not feather colouring. Another identifier is the dark line on the upper neck.

Although the birds are permanent residents on Abaco, they are relatively uncommon. They are not a protected species, and yet unlike some other pigeon and dove species (Mourning Dove, Ring Necked Dove, White-crowned Pigeon, Zenaida Dove) they are not listed among the game birds that have a shooting season. Unlike many species whose range is decreasing for all the usual human-related reasons, this bird appears to be expanding its range – or is possibly being introduced in new areas. Urban development seems not to be not such a deterrent as for other birds, and feeders are also thought to contribute to the spread.

FANCY THAT!

STEVIE NICKS name-checks the White-winged Dove and its call in her 1981 hit “Edge of Seventeen” from her Bella Donna album. If your interest is piqued as the Mac again discuss putting behind them their various differences and prodigious substance sampling to re-form (Glastonbury 2015?), see below. However, rehearing this again (having hidden Bella Donna in a locked drawer 30 years ago) the music has not worn well and her voice – sometimes so exciting – is somewhat fingernails on blackboard.
