Although Costa Rica boasts a vibrant tapestry of resident birds, some feathered friends only honor us during their migratory journeys. One of these visitors is the Louisiana Waterthrush, a cheerful songbird that graces our mountain streams with its presence from March to September.

A Master of Moss
Imagine a tiny brown and white torpedo darting along the edge of a 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 feed in trees, the Louisiana Waterthrush prefers the company of bubbling streams and mossy banks.
Sighting a Waterthrush
Look for a flash of white as the Waterthrush constantly bobs its tail, a characteristic habit that gives it away. Its upper body is a deep earthy brown, while the 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 begins with several clear, piercing whistles, followed by a cascade of complex notes. This vibrant song often fills the air in the mornings and evenings, resonating through the lush Costa Rican mountains.
A Creature of Habit
While here, the Louisiana Waterthrush stays true to its name, frequenting fast-flowing streams with plenty of rocks and pebbles. Our mountain retreat, nestled beside a brook, provides the perfect habitat for these fascinating birds.
A Glimpse into the Waterthrush World
Birdwatchers are in luck! 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 delightful meal. Contrary to its name, the Waterthrush doesn’t swim but fearlessly wades into shallow waters, its sharp beak probing the mossy stones for hidden treats.
A Transient Treasure
The Louisiana Waterthrush honors us with its presence only a few months a 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 of our property. A sighting of the Louisiana Waterthrush will undoubtedly be one of the highlights of your Costa Rican adventure.
