This small wonder, also known as the Cocos Flycatcher (Nesotriccus ridgwayi), is a true Costa Rican gem. Unlike its flashy tropical forest relatives, the Cocos Flycatcher possesses a more understated elegance. Measuring just 13 centimeters, it is a study in quiet grays and browns. A beige belly adds a touch of warmth, while subtle cinnamon wing bars and a pale eyebrow complete its image of discreet beauty.
But don’t be fooled by its modest appearance. The Cocos Flycatcher is a marvel of adaptation, thriving in the lush isolation of Cocos Island, a volcanic speck jutting from the Pacific Ocean about 500 kilometers southwest of mainland Costa Rica. Here, in the green embrace of humid forests, thickets, and swampy areas, the Cocos Flycatcher flits among the dense foliage, a master of camouflage.
Listen closely and you might be rewarded with its captivating song. Unlike the boisterous calls of other flycatchers, the Cocos Flycatcher offers a more delicate serenade. Imagine a brief descending sizzle, a whisper cutting through the forest’s stillness. Some describe it as a trilling that accelerates, followed by an explosive chatter, a melody both intimate and intriguing.
While sightings of the Cocos Flycatcher are a true privilege, for those lucky enough to visit Cocos Island National Park, the chance to witness this endemic marvel flitting among the trees is an unforgettable experience. It is a testament to Costa Rica’s incredible biodiversity, a small jewel nestled in a larger paradise.
