High in the canopy of the Costa Rican mountain forests, a flash of black and white catches your eye. It’s not a rogue zebra escaped from the zoo, but the aptly named Black-striped Woodcreeper, a regular here at our mountain retreat! This distinctive bird is a true mountaineer, perfectly adapted to navigating the vertical world of the trees.

A Striking Climber

The Black-striped Woodcreeper (Xiphorhynchus lachrymosus) is a medium-sized songbird, reaching lengths of 8.5 to 9.8 inches (21.5 to 25 cm). Unlike many woodcreepers, the Black-striped Woodcreeper lacks a flamboyant head crest. Instead, its striking feature is its plumage. True to its name, it boasts a stunning contrast of brownish-black feathers on its face, crown, back, and wings, boldly accented with thick white streaks. These streaks run both above and below, giving it a zebra-like appearance. The sexes are similar, so you won’t need to worry about identifying the male or female during your birdwatching adventures.

A Master of the Tree Trunks

Look for the Black-striped Woodcreeper on the lower portions of tree trunks, especially large trees with rough bark. Its long, slightly decurved bill and sharp claws are perfectly designed for clinging and climbing. Unlike some woodcreepers that spiral their way up trees, the Black-striped Woodcreeper utilizes short hops and flicks of its tail to propel itself upwards. This methodical exploration allows it to probe every crevice and crevice in search of its favorite food – insects and spiders.

A Vocal Climber

While the Black-striped Woodcreeper is a visual treat, it’s also an auditory one. Listen for its distinctive call, a clear descending series of notes that often starts with a stutter. This vocalization helps it maintain contact with mates and defend its territory. You might also hear a drumming sound, created by the bird rapidly tapping its bill against the trunk.

More Than Just Mountains

While the Black-striped Woodcreeper thrives in the mountain forests, its range extends beyond our retreat. You might also encounter this bird in the rainforests of Costa Rica, particularly in the foothills and along the Caribbean slope, in countries like Colombia, Ecuador, Nicaragua, and Panama.

A Birder’s Delight

Whether you’re a seasoned birdwatcher or just starting to explore the wonders of the avian world, the Black-striped Woodcreeper is a Costa Rican treasure. With its striking appearance, fascinating climbing technique, and vocal repertoire, this bird is sure to leave a lasting impression. So, keep your eyes peeled (and ears open) as you explore the mountain forests of our retreat. You might just spot Stripey making its way up a tree trunk!
