Hotel Rivel’s mountainous embrace isn’t just a haven for human guests seeking adventure. Within the verdant expanse of the Costa Rican rainforest, a fascinating cast of avian residents thrives. Today, we turn our binoculars to a particularly elusive character: the Dark-billed Cuckoo (Coccyzus melacoryphus).
A Master of Camouflage
For those hoping for a vibrant burst of color, the Dark-billed Cuckoo might be a tad disappointing. This slender, long-tailed bird embodies the art of camouflage. Its upper parts are a symphony of browns and grays, with the crown and nape boasting a cooler shade. The wings lack the rufous tones found in some cuckoo cousins, opting for a uniform, darker grayish brown. But look closer, and you’ll find subtle beauty in the details.
A Flash of White and a Bold Mask
The underside of the Dark-billed Cuckoo reveals a warm buff color, a welcome contrast to the muted upperparts. But the true stars of the show are the tail feathers. From below, the central pair is a rich brown with black tips, while the others graduate to a dramatic black adorned with contrasting white spots. These markings become a dazzling display when the bird takes flight, momentarily flashing against the emerald curtain of the rainforest.
A Masked Marvel
The Dark-billed Cuckoo’s face is another captivating feature. A bold black “bandit mask” extends across the eyes, adding an air of intrigue. The eyes themselves are a dark, watchful brown, framed by a subtle yellowish eyering. This seemingly simple combination creates a characterful visage, perfect for a bird that prefers the shadows.
A Song in the Depths of the Rainforest
While spotting a Dark-billed Cuckoo can be a challenge, their presence is often announced by their distinctive call. Unlike the clear, “cu-cu” notes of some cuckoos, the Dark-billed Cuckoo delivers a low, almost mournful, “cowl-cowl-cowl” sound. This descending call echoes through the rainforest, a haunting melody that adds to the bird’s mystique.
A Resident of Rainforest Realms
The Dark-billed Cuckoo is a quintessential rainforest dweller. They favor dense woodlands, second growth areas, forest edges, and riparian zones. Plantations and mangroves can also provide suitable habitat. Here, amongst the tangled branches and lush foliage, they find the perfect environment to hunt for their favorite prey: insects. Caterpillars, especially the destructive fall webworms and tent caterpillars, are a particular delicacy.
A Glimpse into the Hidden World
Spotting a Dark-billed Cuckoo requires patience and a keen eye. But for those who take the time to explore the hidden corners of the rainforest, a glimpse of this enigmatic bird can be a truly rewarding experience. It’s a reminder that within the verdant embrace of Hotel Rivel, a fascinating world of creatures awaits discovery. So, keep your binoculars handy, and see if you can unveil the secrets of the Dark-billed Cuckoo!
