High in the Costa Rican mountains, where the emerald embrace of the rainforest meets the crisp kiss of cloud forests, resides an inconspicuous songster – the Scrub Greenlet. Often overlooked amidst the vibrant tapestry of tropical birds, this little wonder holds its own charm.

The scrub greenlet, aptly named for its preferred habitat, is a tiny songbird belonging to the Vireo family. Measuring a mere 4.5 inches in length and tipping the scales at a featherweight 0.4 ounces, it’s a marvel of nature’s miniaturization.

A splash of color in a verdant world: Don’t be fooled by its name. While green dominates the scrub greenlet’s upperparts, with brighter highlights on the wings and rump, a touch of olive graces its head. A subtle yellowish eyering adds a hint of warmth, making its dark bill and pale legs stand out.

Listen for the weary song: Though small in stature, the scrub greenlet boasts a surprisingly loud voice. Its song, a repeated series of “weary-weary-weary” notes interspersed with chirps and squeaks, can be quite distinctive. Keep your ears peeled while exploring the forest edges and second-growth woodlands, their preferred habitat.

A resident of many regions: While you’ll encounter the scrub greenlet throughout Costa Rica, from the lush rainforests of the Caribbean lowlands to the drier Pacific slopes, it thrives particularly well in the mountains. Here, at our mountain retreat nestled amidst the verdant embrace of the Cordillera mountains, you’ll have ample opportunities to spot this little songbird.

A glimpse into their life: Primarily insectivores, scrub greenlets flit amongst the branches, expertly gleaning insects and spiders from the foliage. They are social creatures, often seen in pairs, and their cooperative breeding habits make them fascinating residents of the Costa Rican forests.

A tiny ambassador of the ecosystem: The scrub greenlet, though unassuming, plays a vital role in the rainforest ecosystem. By controlling insect populations, they contribute to a healthy balance in the environment.

Spotting the scrub greenlet: Look for them foraging in the middle and upper levels of trees and shrubs along forest edges, trails, and clearings. Patience and a keen eye are key to spotting this little wonder.

Enhancing your birdwatching experience: While spotting a scrub greenlet can be a delightful surprise, here are some tips to enhance your chances:

• Early mornings are prime time: Birds tend to be most active at dawn and dusk, so plan your explorations accordingly.
• Bring binoculars: Their small size makes binoculars essential for a good look.
• Download a birding app: Apps with bird calls and identification guides can be a helpful tool.
• Join a guided birdwatching tour: Our retreat offers guided tours led by experienced naturalists who can help you spot and identify various bird species, including the scrub greenlet.

So, on your next visit to our mountain retreat, keep an eye out for this little green wonder flitting amongst the trees. With a bit of patience and an appreciation for the small wonders of nature, you might just be rewarded with a glimpse of the scrub greenlet, a tiny ambassador of the Costa Rican rainforest.
