High in the lush canopy of Costa Rica’s rainforests, a flash of movement catches your eye. It’s the Ivory-billed Woodcreeper, a stunning bird with a streaked plumage and a long, pale bill. This resident gracing our mountain retreat is a captivating sight, and for birders, a true delight.
A Forest Acrobat
The Ivory-billed Woodcreeper (Xiphorhynchus flavigaster) belongs to the subfamily Dendrocolaptinae, which includes a fascinating group of ovenbirds. Unlike their oven-building cousins, the Woodcreeper is a master climber, expertly navigating the vertical world of towering trees.
Their strong feet, with two toes pointing forward and two back, provide exceptional grip as they scurry up trunks and branches. Their long, slightly decurved bill acts like a probe, perfect for extracting insects and other invertebrates hidden beneath bark and in crevices.
Striking Yet Subtle
At a glance, the Ivory-billed Woodcreeper might appear all streaks and speckles. But a closer look reveals a beautiful pattern. Their upperparts are a tapestry of black and buff streaks, with a prominent white eyebrow adding a touch of contrast. The underparts are intricately streaked with brown and white, creating a subtle camouflage against the dappled sunlight filtering through the leaves.
The namesake “ivory bill” is indeed pale, but not quite ivory-colored. It’s a light gray or horn-colored, adding a touch of elegance to their overall look.
A Patient Predator
Unlike the hyperactive Streak-headed Woodcreeper, their close relative, the Ivory-billed Woodcreeper is a methodical hunter. They move deliberately up tree trunks, carefully examining every nook and cranny. Their sharp eyes scan for hidden prey, and their long bill allows them to probe deep into crevices and bromeliads, those fascinating plant rosettes that grow on tree limbs.
This patient approach ensures a steady supply of insects, spiders, and other invertebrates that form their diet.
A Sight and Sound to Behold
While the Ivory-billed Woodcreeper is not the most vocal bird, their calls are distinctive. A sharp, high-pitched “tsee” or “tsip” is their most common vocalization. You might also hear a rapid, rattling series of notes, particularly when they are agitated or engaged in territorial defense.
Spotting an Ivory-billed Woodcreeper requires patience and a keen eye. But the reward is a truly unforgettable sight – a glimpse into the remarkable world of Costa Rica’s avian wonders.
