The Costa Rican rainforest is a symphony of sights and sounds. From the raucous calls of the scarlet macaw to the melodic whistles of the collared aracari, there’s always a feathered friend serenading you on your explorations. But nestled amongst the dense foliage, a quieter resident thrives – the enigmatic Slaty Spinetail.

This passerine bird, belonging to the ovenbird family (Furnariidae), is a master of camouflage. Its plumage is a beautiful blend of slaty-gray, with a dash of rufous on the crown and folded wings. This coloration allows it to blend seamlessly into the tangled undergrowth, its presence often betrayed only by its distinctive call.

A Voice in the Thicket

If you’re lucky enough to spot a Slaty Spinetail, it will likely be flitting through the dense vegetation at the forest’s edge, second-growth woodlands, or riparian thickets. Here at our Costa Rican retreat, nestled amidst the mountains, sightings are more common, thanks to the abundant undergrowth that provides them with both shelter and a hunting ground.

While glimpses of this bird may be fleeting, its voice is unmistakable. Listen for a low, stuttered chatter, a series of “chu-chu-chrrrr” sounds that emanate from the depths of the thicket. This persistent call is its way of communicating with other Slaty Spinetails, a secret language carried on the tropical breeze.

A Life Less Ordinary

Unlike its ovenbird relatives known for their elaborate clay nests, the Slaty Spinetail takes a more traditional approach. They construct bulky, spherical stick nests, often 36×43 cm in size, with a long, tubular entrance. These impressive structures can be found high up in a shrub or vine-covered tree, offering a safe haven for their clutch of two or three greenish-white eggs.

A Bird of the Lower Levels

The Slaty Spinetail is primarily a creature of the understory, rarely venturing above the dense vegetation. Here at our mountain retreat, with its lush rainforest teeming with life, you’re most likely to encounter this bird in the lower elevations, typically below 1200 meters.

A Glimpse into the Hidden World

While the Slaty Spinetail may not be the flashiest bird in Costa Rica, its secretive nature and unique habitat make it a fascinating resident of our mountain retreat. If you keep your eyes peeled and listen attentively, you might just catch a glimpse of this elusive bird flitting through the undergrowth, its presence a reminder of the hidden wonders that reside within the Costa Rican rainforest.
