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.

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

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.

Upside down is really just a different angle to get at fruit

Noshing on berries

One in the beak, next one ready in the claw

Tackling something more substantial

More acrobatics

And eventually out on a limb…

CUBAN EMERALDS ON ABACO: JEWELS BEYOND PRICE

CUBAN EMERALDS ON ABACO: JEWELS BEYOND PRICE

Well I don’t want to overstate it, but there cannot be anyone on the planet who has anything but love for hummingbirds. There’s no existing word for ‘fear of hummingbirds’ – ‘colibriphobia‘ is not a ‘thing’. There’s fear of almost everything else, from grass to clouds to plastic bags**… but, surely, not hummers. Here are a few to enjoy.

The females have a wonderful metallic sheen that makes them shimmer in the sunshine. Males are darker: a gorgeous, handsome green. The Emeralds are one of those bird species where it is hard to decide between the sexes which is the more beautiful…

ANTILLEAN NIGHTHAWKS REVISITED

ANTILLEAN NIGHTHAWKS REVISITED

In 2014 I wrote about finding myself – with others on a birding expedition – in the midst of dozens of nighthawks as they swooped and dived (dove?) while hawking for flies. “The birds were quite unperturbed by our presence, and from time to time would zoom past within inches of our heads, making a swooshing noise as they did so”. You can find the post at FAST FOOD ON THE WING.

Nighthawks catch flying insects on the wing, and mostly forage at dawn and dusk – or (more romantically) at night in a full moon.

Besides aerial feeding displays, nighthawks may also be seen on the ground, where they nest. I say ‘nest’, but actually they hardy bother to make an actual nest, but just lay their eggs on bare ground. And, more riskily, this may well be out in the open rather than concealed. The eggs – usually 2 – hatch after 3 weeks or so, and after another 3 weeks the chicks fledge.

Fortunately their colouring enables them to blend in with the landscape – a good example of bird camouflage in natural surroundings.

The photos above are from Sandy Walker (header), Stephen Connett – to whom special thanks for use permission for his great nighthawk and egg images – and the last one by bird legend and author of the locus classicus The Birds of the Bahamas (without which no trip to the Bahamas is complete), Bruce Hallett.

Antillean Nighthawk Chordeiles gundlachii, is a species of nightjar. These birds have local names such as ‘killa-ka-dick’, ‘pi-di-mi-dix’, ‘pity-pat-pit’, or variations on the theme, presumably onomatopoeic. Pikadik-(dik) will do for me. See what you reckon from these recordings (excuse the thick-billed vireo – I think – in the background):

ODD FACT

I have read in several sources that no one knows where these migratory birds spend winter; or else that winter season data is ‘scarce’. So no sensible range maps exist, for example. If you read this, and have antillean nighthawks (as opposed to common nighthawks) all round you in winter, please tell someone – you may hold the key to an ornithological mystery…

As so often, the Bahamas Philatelic Bureau leads the way with natural history stamps. The 15c Antillean Nighthawk above featured in a 2001 bird set. You can see dozens more very excellent Bahamas bird, butterfly, fish, flower and other wildlife stamps HERE.

IN A CLASS OF ITS OWN: THE LIMPKIN

IN A CLASS OF ITS OWN: THE LIMPKIN

The Limpkin has a special status: it is in a Class of its own. Actually, it is in a Family of its own in terms of strict Linnean classification. It is in the Class ‘bird’ and the Order ‘crane and rail’. But there is no other creature in its Family or Genus. So it’s on its own, bird-wise. None like it anywhere. It is ‘monotypic’.

These snail eaters are said to be named for their somewhat lame walking method on their long legs. Their long downcurved bills are shaped to act rather like tweezers when feeding on snails. I’ve never managed to get very close to one – they seem to be quite secretive. But boy, can you hear them when they decide to go for it. If you ever hear this sound – quite possibly at night – now you’ll know what creature is making it…

TEN LIMPID LIMPKIN FACTS TO ENTHRAL YOUR FRIENDS

The Limpkin has its own ‘monotypic’ family – a one-off species of bird
They eat snails and molluscs (also insects, worms & frogs), using their beaks to snatch them
They may leave piles of discarded shells in their favourite feeding sites
The birds are ungainly and awkward: ‘limpkin’ probably derives from their limping gait
Males and females have the same plumage (males being slightly larger)
The beak acts like tweezers – slightly open and closing at the tip – for tweaking snails etc
Territory is defended aggressively, with ‘ritualized charging and wing-flapping’ at intruders
Sex lives: they are monogamous; or polyandrous (a male and more than one female. Tsk.)
They use ‘courtship feeding’ – males will catch and shell a snail and then feed it to a female
They are also known as the ‘Crying Bird’ for their bizarre shrieking call, as used in films**

** Specifically, as a generic jungle noise in Tarzan films; and apparently for the hippogriff in one of the Harry Potter films.

HOOPOES: THE TARGET FOR THE WEEK (NOT ON ABACO!)

HOOPOES: THE TARGET FOR THE WEEK (NOT ON ABACO!)

From time to time, wildlife that is completely alien to Abaco, the Bahamas, or even the Americas will slip under the radar and find a place hereabouts. I’m hoping to find one such during the next few days. It is Upupa epops: the Eurasian hoopoe. This wonderful creature is a bird of the warmer areas of Europe and Asia (orange on the map below), and widespread (non-breeding) in areas further south including Africa.

Very occasionally they are found in the south of England, but we are travelling to the Balearics and the hoopoe is merely incidental to the expedition. I’ve seen them in France, Italy, and on Mallorca… and we are in with a good chance of finding one this coming week. So I’d better to remember to have more than iPhone with me…

The hoopoe’s most distinctive feature is its extraordinary erectile crest, which creates an impressive fan on top of its head. Then there’s attractive colour scheme. And that long, down-curved, insect-pecking beak. And that unmistakeable call, an onomatopoeic name that really fits the species (cf Whip Poor Will):

There is a very real chance of finding and photographing this gorgeous bird, but I appreciate that it’s probably not of sufficient interest Abaco-wise to justify a second post so I’ll probably just put an image on Insta and FB. If any are good enough…

SCOOP (2): AMAZING BLACK SKIMMERS & CHICKS

SCOOP (2): AMAZING BLACK SKIMMERS & CHICKS

Last year I posted about an avian scoop, when black skimmers (Rynchops niger) were actually photographed on Abaco. These wonderful birds are classified WR 4 for Abaco, which means uncommon winter residents (ie roughly September until April). Now I look into it further on the indispensable eBird, there are actually quite a few reported sightings most years on Abaco – especially on the Cays. Furthermore the sightings cover most months except midsummer. So maybe they aren’t so rare after all. But I couldn’t track down any workable Abaco skimmer photographs until Charmaine Albury managed to take a few last Autumn, which led to the gift post title SCOOP. Because that is just how they feed.

Danny Sauvageau is a dedicated birder in Florida, and a brilliant photographer with it. From time to time I feature his work when his camera skills cover a species found on Abaco but for which Abaco images are scarce (or non-existent). All these photographs were recently taken in Pinellas County, Fl., and I’m really grateful to Danny for permission for occasional use of his exceptional photos.

At the moment, the breeding season is well under way, with the hungry chicks being fed as fast as they can swallow. And this is how that looks, thanks to Danny and his immense talent.

And finally… I’d be really pleased to hear about any Abaco skimmer sightings (and I’ll keep an eye on eBird). Bonus points and a theoretical Kalik for photographs!
