‘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.
