Here at our mountain retreat, we revel in the symphony of birdsong that fills the crisp morning air. But Costa Rica’s avian diversity extends far beyond the cloud forests and into the steamy realm of the coastal wetlands. Today, we set our sights – or rather, ears – on a secretive resident of the mangroves and salt flats: the Clapper Rail.
The Clapper Rail (Rallus longirostris) might not be the most vibrantly colored bird, but its elusiveness and fascinating lifestyle make it a worthy addition to our Costa Rican birding catalog. This shy member of the rail family is more often heard than seen. Imagine a chicken-sized, grayish-brown bird with a pale chestnut breast, expertly navigating the dense maze of reeds and tall grasses that line the coast. That’s the Clapper Rail, perfectly camouflaged in its preferred saltwater marsh habitat.
While the Clapper Rail of North America (Rallus crepitans) has a distinct range along the Atlantic and Gulf coasts, its Costa Rican cousin, formerly lumped under the same name, is now recognized as the Mangrove Rail. This taxonomic distinction reflects the subtle differences between these geographically isolated populations.
Despite its covert nature, the Clapper Rail does leave a calling card: its namesake “clapper” call. A loud, sharp “kek-kek-kek,” often delivered in rapid succession, pierces the tranquility of the coastal wetlands. This vocalization serves as a territorial proclamation and a way for individuals to stay connected.
While sightings of the Clapper Rail are uncommon, there are ways to increase your chances. Early mornings and late afternoons, when the light is low and the bird feels more secure venturing out, are prime birding times. Patience and a keen ear are essential, as the Clapper Rail will likely freeze or dash for cover if it senses danger.
If you’re fortunate enough to spot a Clapper Rail, you’ll witness a master of stealth. It effortlessly darts through the marsh vegetation, its long legs and strong feet providing excellent maneuverability. Its slightly downcurved bill, perfect for probing the mud for hidden crustaceans, insects, and small fish, adds another tool to its wetland survival kit.
The Clapper Rail’s preference for saltwater marshes makes it unlikely to be spotted from our mountain retreat. However, birding enthusiasts venturing to Costa Rica’s coastal regions, particularly the Gulf Coast and the Pacific lowlands, should keep an ear out for this intriguing resident of the reeds. The thrill of a Clapper Rail sighting, a testament to its remarkable ability to thrive in a hidden world, will be a memory to cherish.
