Here at our mountain retreat, nestled amidst the emerald embrace of Costa Rica’s highlands, we’re surrounded by a symphony of birdsong. Today, we turn our ears to a subtler melody, that of the aptly named Streaked Xenops (Xenops rutilans).
This little wonder, barely reaching 5 inches in length, is a master of camouflage. Its plumage is a beautiful tapestry of browns, buffs, and rufous, with streaks adorning its head, back, and underparts. A buffy eyebrow and a clean white stripe on its cheek further enhance its cryptic appearance.
While the Streaked Xenops might not be the flashiest bird, its inconspicuousness serves a purpose. It’s a champion climber, flitting about on tree trunks and branches in all directions, much like a treecreeper. Unlike its treecreeper cousin, however, the Xenops lacks a prop-like tail for balance. This acrobatic feat makes it a marvel to observe, but its small size and preference for the upper canopy can make it a challenge to spot.
Listen closely, however, and you might be rewarded. The Streaked Xenops’ song is a series of 5 or 6 metallic “zeet” notes, a chattering call that betrays its presence amongst the leaves.
These insectivores are meticulous hunters, gleaning arthropods like larvae of wood-boring beetles from the bark and crevices of trees. They’re also opportunistic, sometimes snatching flying termites mid-air!
Found throughout the tropical New World, from Costa Rica and Trinidad south to Bolivia and Argentina, the Streaked Xenops prefers the cool, damp embrace of montane forests. In Costa Rica, you might encounter them in the foothills and mountains, between elevations of 2,000 and 7,200 feet. They’re particularly fond of secondary forests and areas with opened-up growth, where they can find ample foraging opportunities.
The Streaked Xenops is currently listed as “Least Concern” by the IUCN. However, their populations might be declining due to habitat loss. By protecting Costa Rica’s precious rainforests, we ensure a haven for these fascinating feathered acrobats and countless other species.
So, on your next nature walk here at our mountain retreat, keep your ears tuned for the subtle “zeet” calls and your eyes peeled for a flash of brown streaked with rufous. With a little patience, you might just be lucky enough to catch a glimpse of the Streaked Xenops, a tiny titan of the Costa Rican highlands.
