Upemba National Parc, DRC – #BirdyTuesday

If you spot a flash of blue-black darting through the open woodlands of Upemba, take a closer look—you may have encountered the elusive Sharpe’s Drongo (Dicrurus sharpei), one of the park’s lesser-known but fascinating avian residents.

Recently recognized as a distinct species, Sharpe’s Drongo was once grouped with the Square-tailed Drongo (Dicrurus ludwigii). However, thanks to genetic and morphological studies, it now enjoys its rightful status, celebrated for subtle but important differences: a square-tipped tail without a deep fork, a dull purplish-blue iridescence, and the absence of the white underwing markings that characterize some of its close relatives.

At just around 19 centimeters long, this small drongo dazzles with its glossy blue-black plumage, red eyes, and confident, upright posture reminiscent of a shrike. Males are typically glossier than females, but both share the same quietly commanding presence as they perch watchfully in the forest.

Sharpe’s Drongo prefers drier habitats than its cousin, the Shining Drongo. In Upemba, it thrives in open forests, thick woodlands, and dense thickets, blending seamlessly into the diverse tapestry of the park’s landscapes.

One of the joys of encountering this bird is hearing its vibrant vocalizations. Its explosive and varied song, filled with whistles, rasps, and squeals, often bursts forth as a duet between a pair. Despite its impressive soundscape, Sharpe’s Drongo is not as bold or conspicuous as the Fork-tailed Drongo, often staying watchful and discreet.

Feeding primarily on insects, Sharpe’s Drongo performs a critical ecological role. By regulating insect populations, it helps maintain the health of vegetation and reduces the likelihood of insect outbreaks. It also forms a vital link in the local food web, serving as prey for larger birds and mammals. Furthermore, its presence offers valuable clues to scientists about the health of its habitat, making it a potential indicator species for environmental changes.

So next time you wander through Upemba’s woodlands, keep your eyes – and ears – open. A glimpse of glossy black and a chorus of energetic calls might just reveal the quiet guardian of these forests: the remarkable Sharpe’s Drongo.
