‘LIKE’ THE CLAPPERS: ON THE RAILS IN ABACO

CLAPPER RAILS Rallus crepitans are elusive birds of mangrove swamp and marsh, more frequently heard than seen. They tend to lurk around in foliage and are easy to overlook. They are creatures of the margins rather than open ground. You may come across one foraging secretively, beak-deep in the mud.

Tom Sheley’s wonderful photos featured here of a preening clapper rail were taken during our backcountry explorations to locate and photograph species for BIRDS OF ABACO.  By being  both patient and an early riser, Tom managed to capture this fine bird engaging in some quality grooming. The one below is ‘vocalising’ – known in rails as ‘rousing’ – in mid-preen.

Clapper rails are capable of swimming and even of flying if they choose to. However the most likely activities you are likely to observe will be skulking,  picking their way through marginal  vegetation, or (if you are lucky) doing some beak-deep foraging in the mud. Occasionally they run, a process that looks endearingly comical and which possibly gives rise to their name.

It almost goes without saying nowadays, but the biggest threat to these rather charming inoffensive birds is habitat loss. Which is to say, mankind either directly or indirectly. Drive the bulldozers through the mangroves and marshland of sub-tropical coastal areas, chuck down a few acres of concrete… and the clappers will very soon become clapped out. As they will if the climate we are unarguably changing ruins their unobtrusive lives.

COMPULSORY LINGUISTIC STUDY

When I last wrote about this species its binomial name was Rallus longirostris ie simply ‘long-beaked rail’. Since then the increasingly frenetic annual turmoil of official AOU shuffling species about and messing with their names has resulted in the clapper rail being re-designated Rallus crepitans or ‘rattling / rustling rail’, I assume from the call. There are other rail-name innovations that, reading about them just now, made me crack open a beer instead of wanting to tell you about them.

OPTIONAL LINGUISTIC DIVERSION

“TO RUN LIKE THE CLAPPERS”. This phrase seems to be fairly recent, most likely originating as military (?Air Force) slang early in WW2 or possibly from earlier conflicts. Some suggest it is a rhyming slang bowdlerisation of ‘run like hell’ with ‘clapper(s)’ standing for ‘bell’, along the lines of the Cockney “I bought a brand new whistle” (whistle and flute = suit). Almost all plausible explanations relate to bells, and some argue that it simply reflects the rapid speed of the clapper of a vigorously rung handbell. This derivation as a link to the bird seems tenuous at best.

ABACO BIRDS… THAT RUN LIKE THE CLAPPERS


Clapper Rail on Abaco by Sandy Walker

ABACO BIRDS… THAT RUN LIKE THE CLAPPERS

That is, essentially, because they are indeed Clappers. Rallus longirostris to be precise, or Clapper Rails. There are 4  rail species on Abaco, the Clapper being a permanent resident and not particularly uncommon. The others are the Virginia Rail and the Sora, both winter residents and less common (or in the Sora’s case, perhaps more furtive and less easy to find); and the Black Rail, which is generally agreed to be a ‘hypothetical’ for Abaco. That means they are believed to exist on Abaco but there are no confirmed sightings let alone any photos of one. However, last summer while we were taking a truck into the backcountry of South Abaco to locate hard-to-find birds for “The Birds of Abaco” book, the distinctive call of a Black Rail call was heard independently by two people on two different days in two different locations. I’ve heard another report since then. So they are out there somewhere, but keeping their heads down. The first to find one will have a considerable avian scoop!

Let’s start with some fabulous photographs by Tom Sheley. We used the first one in the book. By being patient, Tom managed to capture this bird having a quality preening session. Here are 4 shots from the sequence, including a rare one of the bird calling.

Clapper Rails are elusive birds of mangrove swamp and marsh, more frequently heard than seen. They tend to lurk around in foliage and are easy to overlook. You may come across one foraging secretively in the mud. Although they can both swim and fly, they prefer to keep both feet on the ground.When running, these rails look endearingly comical.

STOP PRESS Uli Nowlan has sent her photo of a Clapper Rail, taken at the ponds north of Treasure Cay – a reminder that there is good birding to be done in that area of North Abaco – the bird action is not confined to South Abaco below MH…
