svartdrongo Dicrurus macrocercus

An adaptable songbird of open areas such as farmland, forest edge, meadows, wetlands, and fields and a common sight as a familiar dark silhouette perched on wires, fences, or snags. Black plumage flashes blue and green iridescence in favorable light, though much less so than in Hair-crested or Bronzed Drongo. A pugnacious species, frequently chasing away larger birds with repeated dives and harsh chattering calls. A skilled mimic of other species, and a strong songster in general, delivering a wide range of pleasant fluty calls, harsh chattering, nasal notes, and high sharp whistles.
