RUDDY TURNSTONES: PICTURE PERFECT ON ABACO (1)


RUDDY TURNSTONES: PICTURE PERFECT ON ABACO (1)

Ruddy Turnstone, the Marls, Abaco, Bahamas (Tom Sheley)

I very rarely – almost never –  publish single or pairs of images, not least because I enjoy the bits of research and writing that cover a topic more thoroughly. However, today I was going through the photographic archive from my book BIRDS OF ABACO and came across these RUTUs photographed on the Marls by contributor Tom Sheley.

TBH turnstones are among the easiest shorebirds to photograph. They are pleasingly tame, so you can get quite close to them without ruffling their feathers. They aren’t tiny and they are pretty and quite colourful. And they are fairly abundant and so not hard to locate… but they make it hard to get a really good bright, clear photo. Or is that just me…? Anyway, Tom definitely has the camera skills required.

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…

RUDDY TURNSTONES ON THE BEACH IN ABACO

Ruddy Turnstones Arenaria interpres are well-known shore birds around the world. They used to be classified as plovers, but are now counted with sanderling. Fortunately they are distinctive enough not to be confusable with the many other species of shore bird with which they mix.Ruddy Turnstones at Delphi, Abaco 13

Their foraging methods are classified into 6 broad categories, though I imagine that if peckish, they may opt for all of these in the one feeding session.

  • Routing — rootling through piles of seaweed by flicking, ‘bulldozing’, and pecking it to expose small crustaceans or gastropod molluscs hidden underneath.
  • Turning stones — living up to its name name, flicking stones with its bill to uncover hidden snaily and shrimpy creatures.
  • Digging —  using small flicks of the bill to make holes in sand or mud and then gobbling up the prey revealed.
  • Probing — inserting the bill right into the ground to get at concealed gastropods.
  • Hammering — cracking open shells using the bill as a hammer, then winkling out the occupant. 
  • Surface pecking — short, shallow pecks to get at prey just below the surface of the sand.

Between them,  these turnstones seem to be using methods 1, 3, 4 and 6Ruddy Turnstones at Delphi, Abaco 2
