Costa Rica’s lush rainforests are home to a vibrant tapestry of birdlife. Among the dazzling array of feathered friends, the Brown-capped Tyrannulet stands out as a tiny gem, easily overlooked yet possessing a captivating charm.

A Master of Camouflage:

This miniature flycatcher, measuring a mere 4.3 inches in length, is a master of blending in with the forest canopy. Its upper body is cloaked in a rich, warm brown, perfectly mimicking the hues of tree bark and leaves. A bright white eyebrow, like a delicate paintbrush stroke, adds a touch of elegance to its face.

A Glimpse of Gold:

Beneath its brown cap, the Brown-capped Tyrannulet boasts a vibrant yellow belly, a flash of sunshine amidst the emerald foliage. This contrasting color helps to identify the bird, especially when perched motionless on a branch.

A Melodious Songster:

While its size might suggest otherwise, the Brown-capped Tyrannulet possesses a surprisingly loud and clear song. Its call is a series of descending, plaintive whistles, often described as “sweet” and “melancholic.” This distinctive melody helps birders locate these elusive creatures within the dense rainforest canopy.

Habitat and Habits:

Primarily found in the lowlands of Costa Rica, the Brown-capped Tyrannulet favors the dappled sunlight filtering through the rainforest canopy. It frequents both pristine and secondary forests, often joining mixed-species flocks as they forage for insects amongst the leaves.
