While Costa Rica boasts a vibrant tapestry of resident birds, some feathered friends grace us only during their migratory journeys. One such visitor is the Louisiana Waterthrush, a spritely songbird gracing our mountain streams with its presence from March to September.
A Master of the Mosses
Imagine a tiny brown and white torpedo darting along the edge of a rushing stream. That’s the Louisiana Waterthrush in action! This palm-sized warbler (scientific name: Parkesia motacilla) is a master of its domain, flitting between rocks and roots with impressive agility. Unlike most warblers that forage in the trees, the Louisiana Waterthrush prefers the company of gurgling streams and mossy banks.
Spotting a Waterthrush
Look for a flash of white as the Waterthrush bobs its tail constantly, a characteristic habit that gives it away. Its upper body is a rich, earthy brown, while its underparts are a clean white with bold black streaks. A bright white eyebrow adds a touch of charm, and its legs are a distinctive pinkish-red.
A Song of Clear Whistles
The Louisiana Waterthrush is not shy about announcing its presence. Listen for its beautiful song, a melody that starts with several clear, piercing whistles followed by a cascade of complex notes. This vibrant song often fills the air in the early mornings and late afternoons, echoing through the lush Costa Rican mountains.
A Creature of Habit
While here, the Louisiana Waterthrush remains true to its name, frequenting fast-flowing streams with an abundance of rocks and pebbles. Our mountain retreat, nestled beside a gushing stream, provides the perfect habitat for these fascinating birds.
A Glimpse into the Waterthrush’s World
Birdwatchers are in for a treat! The Waterthrush is a tireless forager, constantly on the move. It doesn’t hop or fly much, preferring to walk briskly along the stream’s edge, its sharp eyes scanning for prey. Aquatic insects, small crustaceans, and even tadpoles become its delicious meals. Unlike its name suggests, the Waterthrush doesn’t swim, but it wades fearlessly into shallow water, its sharp bill probing the mossy stones for hidden treats.
A Transient Treasure
The Louisiana Waterthrush graces us with its presence for just a few months each year. But during this time, it adds a touch of dynamism to our mountain retreat. So, keep your eyes peeled (and ears open) for this little bundle of energy as you explore the streams and trails around our property. A sighting of the Louisiana Waterthrush is sure to be a highlight of your Costa Rican adventure!
