As the twilight descends upon our mountain retreat here in Costa Rica, a chorus unlike any other begins to rise. The symphony of the rainforest quiets, replaced by the chirps and calls of nocturnal creatures. Among these nighttime serenaders is the Chuck-will’s-widow, a captivating bird with an equally captivating song.
While you won’t find the Chuck-will’s-widow flitting through the vibrant foliage during the day, its presence is undeniable come nightfall. This member of the nightjar family is more often heard than seen. But for those patient observers rewarded with a glimpse, the sight is as remarkable as the sound.
A Master of Camouflage
The Chuck-will’s-widow is a master of disguise. Its plumage ranges from warm browns to rich grays, intricately patterned to resemble dead leaves. This cryptic coloration allows it to blend seamlessly into the branches and bark of the trees it inhabits. Spotting one perched motionless during the day is a feat in itself – a testament to its exceptional camouflage abilities.
The Song of Its Namesake
But as dusk deepens, the Chuck-will’s-widow sheds its cloak of invisibility. Its haunting song, the very source of its peculiar name, fills the night air. The clear, whistled call of “chuck-will’s-widow,” repeated at regular intervals, is an unmistakable melody echoing through the mountains. This persistent song serves two purposes: attracting mates and marking territory.
A Glimpse in the Night
If you’re lucky enough to catch sight of a Chuck-will’s-widow in flight, you’ll be struck by its size. It’s a surprisingly large bird for a nightjar, with a broad head and long, powerful wings. Its large eyes, reflecting an orange glow in the moonlight, are another distinctive feature.
While sightings are uncommon, you might occasionally spot a Chuck-will’s-widow perched on a low branch or even on the road at night, its eyes gleaming in your headlights. It will likely take flight with a burst of silent wings, perhaps uttering a few low clucks in protest at the disruption.
A Transient Visitor
The Chuck-will’s-widow is a seasonal visitor to Costa Rica’s mountains. It migrates from the southern United States and Mexico, gracing us with its presence during the breeding season, which typically lasts from April to September. Come fall, it embarks on its journey south, wintering in the West Indies, Central America, and parts of South America.
A Treat for the Ears
While a glimpse of the Chuck-will’s-widow is a rare privilege, its haunting song is a nightly occurrence at our mountain retreat. As you settle into your comfortable cabin, listening to the nocturnal symphony unfold, the clear, whistled call of the Chuck-will’s-widow weaves its magic, creating a truly unforgettable Costa Rican experience.
