‘RAISE AWARENESS’: SPOTTED EAGLE RAYS

Mention of rays may conjure up thoughts of the familiar southern stingrays that populate the bright shallows and colourful reefs of the Bahamas. But there are other ray species out there gracefully patrolling the coral reefs – and one of these species is the spotted eagle ray (Aetobatus narinari).

These fish (for that is what they are) are not uncommon. In fact they are found in tropical oceans worldwide (though there is a taxonomic distinction between the Atlantic version and the Pacific / Indo-Pacific ones). Note the concentration in the Caribbean sea.

Spotted eagle rays obviously have spots, but they are not notably eagle-like to look at. In fact, their snouts resemble a duck’s bill, and in some place they are less glamorously known as the duckbill ray. The ‘eagle’ part relates to the way in which they use their wings and appear to be soaring as they glide effortlessly through the water (see videos below).

Despite their global presence, these rays are categorised as ‘near-threatened’ on the IUCN Red List. Aside from vulnerability to predators including many types of shark, the rays may be caught as bycatch. In some areas they suffer entanglement in shark nets. And unsurprisingly there is a trade for them for large commercial aquariums. For the Atlantic species, Florida has taken a lead by banning fishing for, landing, buying or trading in spotted eagle rays.

10 ESSENTIAL FACTS ABOUT SPOTTED EAGLE RAYS

  • They have 2 – 6 venomous barbed spines at the base of the tail
  • Adults are among the largest rays, with a 10 ft wingspan
  • They can leap clear of the water, and may do this more than once at a time
  • Occasionally they land in boats, to the consternation of all concerned
  • Their main diet is small fish and crustaceans, & sometimes octopuses
  • Their broad snouts are used to dig food out of the seabed as they forage
  • The rays are basically shy but may be curious of divers & snorkellers
  • They suffer from parasites, both externally and in their gills
  • Ray sex is quite physical, yet actual mating is brief (up to 90 secs…)
  • The female hatches her eggs internally, then her ‘pups’ are born live a year later

 VIDEO SHOWCASE
These 3 short videos demonstrate the grace and beauty of spotted eagle rays as they glide elegantly around the reefs. The first (50s) was taken off Grand Bahama by Fred Riger (Melinda’s husband, for those who follow the underwater forays hereabouts); then one by Stephen Dickey (2:12) ; and finally one from Wildscreen Arkive (2:00).

LEAST (BUT NOT LAST) SANDPIPERS ON ABACO

LEAST (BUT NOT LAST) SANDPIPERS ON ABACO

There are 23 sandpiper species recorded for Abaco. Of those, 4 or 5 are vanishingly rare vagrants recorded once or twice in recent history (i.e. since about 1950).

Discounting those, the ones you are likely to encounter range from the large  (whimbrel, yellowlegs, dowitchers, stilts) to the small. Or, in the case of the least sandpiper, the least big of all. They are bigly little. Least Sandpiper, Delphi Beach, Abaco (Charles Skinner)

The binomial name of the least sandpiper – Calidris minutilla – is an apt clue to their size, the second part being Latin for “very small”. On Abaco, they are fairly common winter visitors, and each season a handful of them make their home on the beach at Delphi, where these photos were taken. Least Sandpiper, Delphi Beach, Abaco (Charles Skinner)

Along with their small sandpiper compadres such as SANDERLING, these busy, bustling birds of the shoreline are the ones known as “peeps” (also as stints). Least Sandpiper, Delphi Beach, Abaco (Charles Skinner)

Least Sandpipers breed in the northern tundra areas of North America. Like many or most shorebirds, newly hatched chicks are able to fend for themselves very quickly. It sounds unlikely I know, but within a couple of weeks or so they have fledged. Least Sandpiper, Delphi Beach, Abaco (Charles Skinner)

The birds forage on mudflats, in the tideline on beaches, and in wrack. They will probe into soft sand, sometimes the full length of their beak. They will even burrow right under weed to get at the concealed goodies. Their diet consists mainly of small crustaceans, insects, and snails.Least Sandpiper, Delphi Beach, Abaco (Keith Salvesen)

A GREAT EGRET MAKES A SPLASH…


A GREAT EGRET MAKES A SPLASH…

I’m quite a  fan of bird action sequences. Top quality ones, I mean, not the rubbishy ones that I have tried to accomplish with either (a) a camera I understand but is not sophisticated enough for such use; or (b) a more serious camera that I never got the hang of, was secretly a bit ‘overawed by’ (= scared of), and which met a watery end when I was photographing sanderlings on the beach while standing in the sea…

Among the photographers who kindly let me use their images from time to time are a couple who are especially adept with sequential shots. One is Danny Sauvageau, a Floridian who combines great bird photography with a tireless capacity for tracking down banded birds at migration time. Here is his Great Egret catching breakfast.

CLAPPER RAILS ON ABACO: A SMALL SHOWCASE

CLAPPER RAILS ON ABACO: A SMALL SHOWCASE

Just over 3 years ago, THE BIRDS OF ABACO was published and launched at the Delphi Club. The book was intended to showcase the wonderful and varied bird life on Abaco – home to endemics, permanent residents, seasonal residents, and a wide variety of migrating transients. The book has been most generously received and supported – though I have to report that already its definitive checklist (dating from 1950) has become outdated with the recording of 6 additional species on Abaco, featured elsewhere in this blog.

Clapper Rail, Abaco, Bahamas (Tom Sheley / Birds of Abaco)

Tom Sheley was one of the main photographic contributors to the book, and I had the good fortune to coincide with one of his trips to Abaco, when he was armed with significant photographic weaponry; and to accompany him on some of his photographic day trips (not including the early morning ones, in my case). This clapper rail is one of my favourites of his photo sequences of a bird being a bird – preening, stretching, calling – in its own habitat.

Clapper Rail, Abaco, Bahamas (Tom Sheley / Birds of Abaco)

My one regret about my involvement  in producing the book (it took 16 months) and more generally in the wildlife of Abaco is that I have entirely failed to progress to sophisticated (expensive) photographic equipment capable of producing images the quality of Tom’s. Yes, I’ve moved on from compacts (ha!) to bridge cameras (Panasonic Lumix + lens extender), and some results ‘make the cut’. But my move up to a Canon SLR was mainly disastrous, and when eventually I inadvertently drowned it (I overbalanced while photographing shorebirds from breaking waves. Total immersion. Total stupidity.) I felt an unexpected sense of relief. A blessing really – I never understood it, nor in my heart of hearts (if I’m honest) really wanted to… But my feeble struggle made me realise and appreciate the enormous skill of those like Tom who take ‘National Geographic’ quality photographs. It’s not just the equipment – it’s knowing exactly how to use it, and often in a split second…

RUDDY TURNSTONES ON ABACO: BEACH NOSHING

RUDDY TURNSTONES ON ABACO: BEACH NOSHING

Some birds are named for the sounds they make (bobwhite, chuck-will’s-widow, pewee, killdeer). Some are named for their appearance (yellow-rumped warbler, painted bunting). And some are named for what they do (shearwater, sapsucker – but definitely NOT killdeer). The ruddy turnstone Arenaria interpres is in the last two of these categories: it looks ruddy and it literally turns stones to get at the goodies underneath.

Ruddy Turnstones, Delphi Beach Abaco Bahamas (Keith Salvesen)

And they don’t just turn stones to look for food. Someone with a lot of patience has defined 6 specific methods by which a turnstone forages for food:

  • Turning stones by flicking them with its beak
  • Digging using its beak to flick away sand or earth (see video below)
  • Routing around in piles of seaweed to expose food under it
  • Surface pecking with short, shallow pecks for food just below the surface
  • Probing by simply sticking its beak deep into soft sand or ground
  • Hammer-probing to crack open a shell and get at the occupant

Ruddy Turnstones, Delphi Beach Abaco Bahamas (Keith Salvesen)

In these photos taken on a rather gloomy day on the Delphi beach, a combination of mainly digging and routing is going on. Note the sandy beak of the RUTU below, right up to the hilt.

This short video shows how effective the RUTU method is. It was fascinating to watch the team work their way through and around the piles of weed on the beach, flicking sand vigorously in their quest for sandflies or whatever. Watch the sand fly! Pity it wasn’t a sunny day – the photos might have looked a bit more cheerful…

ABACO (CUBAN) PARROTS: GETTING FRUITY

ABACO (CUBAN) PARROTS: GETTING FRUITY

To be honest, the header image is not the sort of ‘fruity’ I had in mind, which was intended to have an entirely dietary connotation. I’m not quite sure what these two are up to – not procreation, I think, in that precarious situation. It looks non-aggressive… so maybe just having fun and… er… hanging out together.

Here are some Abaco parrots doing what they love to do in between group squawking sessions: gorge themselves on fruit, and getting at it any which way.
