LIKE THE CLAPPERS: LEARN THE RAILS ON ABACO
Note: You may find ads in this post. This is because WordPress / AI has now decided that you (dear reader) and I (angry author) are presumed to be up for car insurance deals, slimming advice, and incontinence apparatus. I’m probably going to have to buy my way into a new contract, as they presumably intend.
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 – creatures of the margins rather than of open ground. If lucky, 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 backcountry explorations to locate and photograph species for BIRDS OF ABACO. By being an early riser and a patient cameraman, Tom managed to capture this fine bird engaging in some quality grooming. The one below is also ‘vocalising’ – also known in rails as ‘rousing’.
CALL
AGGRESSIVE CALL
Clapper rails are capable of swimming and even of flying if they choose to (which isn’t often). However the most likely activity you will observe is skulking, picking their way quite delicately through marginal vegetation, or (if you are lucky) doing some serious beak-deep foraging in the mud. Their foraging is made easier by the fact that they are omniverous.

Occasionally they run, a process that looks endearingly comical and which possibly gives rise to their name (see below).
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 bulldozers through the mangroves and marshland of sub-tropical coastal areas, chuck down a few acres of concrete and tarmac… and the clappers will very soon be clapped out. As they will if the climate we have unarguably changed irrevocably ruins their unobtrusive lives.
ADVISORY LINGUISTIC STUDY
When I first wrote about this species, its binomial name was Rallus longirostris ie simply ‘long-beaked rail‘. Which it is. Then came an annual official AOU shuffling of species and revision of names. The clapper rail was re-designated Rallus crepitans or ‘rattling / rustling rail‘. Which it does, but it also has other vocalisations (try the sound-files above). So maybe less clear-cut for ID purposes (there were other rail name innovations that, reading about them, made me crack open a beer instead of wanting to tell you about them. I’m old-school.
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’ve bought a new whistle” (whistle and flute = suit). Almost all plausible explanations relate to bells: the speed of the clapper of a vigorously rung handbell. One stand-out meaning relates to the historical era of City prostitution and the high risk of syphilis (‘pox’) or gonnorrhea (‘clap’). You can probably make the link.
