The *Dicrurus macrocercus*, commonly known as the black drongo, is a sleek and agile bird found across the Indian subcontinent, Southeast Asia, and parts of China. This species is known for its glossy, black plumage and distinctive forked tail, which it often fans out during flight. Measuring around 28 to 30 cm (11 to 12 inches) in length, the black drongo has a slender body, sharp beak, and striking red or brown eyes, adding to its bold appearance.

The black drongo is highly territorial and fearless, often seen perched on open branches, telephone wires, or fences, from where it swoops down to catch insects mid-flight. Its diet mainly consists of flying insects like bees, wasps, and dragonflies, but it will also feed on small reptiles and occasionally nectar. Despite its relatively small size, the black drongo is known for its aggressive behavior, fearlessly chasing away larger birds, including raptors, from its territory.

This bird thrives in open habitats such as farmland, grasslands, and wooded areas. Its ability to adapt to human-modified landscapes has made it a common sight in rural and urban environments. The black drongo is admired for its bravery, earning it local names like "king crow" in various regions.
