The Square-tailed Drongo, Dicrurus ludwigii, presents a striking figure with its glossy black plumage, though the wings appear somewhat duller. This small, yet bold avian measures at a modest 19 cm (7.5 inches) in length. The male of the species boasts a more pronounced sheen than the female. Both sexes have a robust black bill and a captivating red eye, contributing to their distinctive appearance.
Distinguishing the Square-tailed Drongo from its relatives can be quite straightforward. It is smaller in size compared to the Fork-tailed Drongo and lacks the pronounced forked tail that characterizes its cousin. When perched, it adopts a very upright stance, reminiscent of a shrike, and its short legs are notable. Observers should look for these key features for accurate identification.
These birds are typically found in forests or areas with dense bush, where they can be seen perched prominently, surveying their domain.
The Square-tailed Drongo is a common resident breeder in southern Africa, with its range extending from Somalia and Kenya in the north, down through Tanzania, Angola, Zambia, Malawi, Mozambique, and into South Africa.
Despite their small stature, Square-tailed Drongos are known for their aggressive and fearless nature. They will not hesitate to confront larger species if they perceive a threat to their nest or young. Their behavior includes flycatching or foraging for prey on the ground.
The vocalizations of the Square-tailed Drongo are quite harsh, with a characteristic 'cherit-cherit' call that can often be heard within their habitat.
The breeding habits of these birds involve the construction of a cup-shaped nest situated high in a tree fork. They typically lay two to three eggs.
The Fork-tailed Drongo is the most similar species, but can be differentiated by its larger size and deeply forked tail. It also prefers more open habitats compared to the Square-tailed Drongo.
As insectivores, Square-tailed Drongos primarily feed on insects, which they adeptly catch in flight or pick off from the ground.
The IUCN Red List classifies the Square-tailed Drongo as Least Concern, indicating that, at present, there are no immediate threats to its population numbers.
